0.说明
内容会有点多，但是下面的内容都是自己在学习LNMP环境搭建过程中的完整再现，所以非常具有参考价值！
下面用一个以最小化方式（Minimal）安装的CentOS 6.5操作系统为例，演示LNMP环境完整搭建过程，并且最后部署了一个WordPress博客，最后完成的效果如下：
1.关于实验环境的说明
本次实验的测试环境使用的宿主机操作系统为Windows 7，在Vmware虚拟机安装CentOS 6.5，说明如下：
宿主机操作系统Windows 7
虚拟机安装的操作系统CentOS 6.5
虚拟机操作系统上网方式NAT
而当使用NAT的方式进行上网时虚拟机、宿主机之间的网络连接关系可如下所示：
关于为什么网络拓扑结构是这样的，这里不展开说明，可以参考博主的另一篇博文《在实践中深入理解VMware虚拟机的上网模式NAT模式》，这篇文章深入地分析了VMware虚拟机使用NAT模式上网时的网络结构细节，相信看完这篇文章后，这里搭建Nginx的实验环境也就很容易理解了。
所以首先，应该是自己先配置好网络环境，让宿主机跟我们的虚拟机可以通信，实际上，如果理解了VMware虚拟机上网方式的原理，同时对CentOS的网络配置也很熟悉，这一步是可以很轻松完成的，这里就不给出过程了，这里所用的IP地址跟上面的图示是一样的。
最后，我们是在宿主机上访问我们搭建的WordPress博客的，非常不错，可以体验一下！
2.LNMP环境搭建：Nginx安装、测试与域名配置
事实上，在另一篇博文中有非常详细的介绍《在CentOS上编译安装Nginx+实验环境搭建+测试》，不过这里为了完整性，依然会给出所有步骤，只是过程会简化很多。
（1）Nginx安装
1.安装Nginx依赖函数库pcre、openssl-devel
[root@leaf ~]# yum install -y pcre pcre-devel openssl openssl-devel ...... [root@leaf ~]# rpm -q pcre pcre-devel openssl openssl-devel pcre-7.8-7.el6.x86_64 pcre-devel-7.8-7.el6.x86_64 openssl-1.0.1e-48.el6_8.4.x86_64 openssl-devel-1.0.1e-48.el6_8.4.x86_64
2.下载安装Nginx
这里使用Nginx1.6.3，如下：
# 下载Nginx [root@leaf ~]# yum install -y wget [root@leaf ~]# mkdir tools [root@leaf ~]# cd tools/ [root@leaf tools]# wget http://nginx.org/download/nginx-1.6.3.tar.gz [root@leaf tools]# ll 总用量 788 -rw-r--r--. 1 root root 805253 4月 8 2015 nginx-1.6.3.tar.gz # 解压缩 [root@leaf tools]# tar zxf nginx-1.6.3.tar.gz [root@leaf tools]# ll 总用量 792 drwxr-xr-x. 8 1001 1001 4096 4月 7 2015 nginx-1.6.3 -rw-r--r--. 1 root root 805253 4月 8 2015 nginx-1.6.3.tar.gz # 指定编译参数 [root@leaf tools]# yum install -y gcc # 需要先安装gcc [root@leaf tools]# mkdir /application # 作为Nginx的安装目录 [root@leaf tools]# useradd nginx -s /sbin/nologin -M [root@leaf tools]# tail -1 /etc/passwd nginx:x:500:500::/home/nginx:/sbin/nologin [root@leaf tools]# cd nginx-1.6.3 [root@leaf nginx-1.6.3]# ./configure --user=nginx --group=nginx --prefix=/application/nginx-1.6.3/ --with-http_stub_status_module --with-http_ssl_module [root@leaf nginx-1.6.3]# echo $? # 结果输出0则说明命令执行成功 0 # 编译 [root@leaf nginx-1.6.3]# make [root@leaf nginx-1.6.3]# echo $? 0 # 安装 [root@leaf nginx-1.6.3]# make install [root@leaf nginx-1.6.3]# echo $? 0 # 建立安装目录的软链接 [root@leaf nginx-1.6.3]# ln -s /application/nginx-1.6.3/ /application/nginx [root@leaf nginx-1.6.3]# ls -l /application/ 总用量 4 lrwxrwxrwx. 1 root root 25 3月 4 04:28 nginx -> /application/nginx-1.6.3/ drwxr-xr-x. 6 root root 4096 3月 4 04:27 nginx-1.6.3
（2）Nginx测试
1.启动Nginx
[root@leaf ~]# /application/nginx/sbin/nginx -t # 检查配置文件 nginx: the configuration file /application/nginx-1.6.3//conf/nginx.conf syntax is ok nginx: configuration file /application/nginx-1.6.3//conf/nginx.conf test is successful [root@leaf ~]# /application/nginx/sbin/nginx # 启动Nginx服务
2.CentOS上验证Nginx服务
[root@leaf ~]# netstat -lntup | grep 80
tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 3929/nginx
[root@leaf ~]# curl localhost
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
body {
width: 35em;
margin: 0 auto;
font-family: Tahoma, Verdana, Arial, sans-serif;
}
</style>
</head>
<body>
<h2>Welcome to nginx!</h2>
<p>If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.</p>

Commercial support is available at
<a href="http://nginx.com/">nginx.com</a>.</p>
<p><em>Thank you for using nginx.</em></p>
</body>
</html>3.宿主机上验证Nginx服务
在宿主机浏览器上输入CentOS主机的IP地址10.0.0.101，如下：
（3）域名配置
这一部分的内容在另一篇博文也有很详细的介绍《Nginx配置多个基于域名的虚拟主机+实验环境搭建+测试》，可以参考一下，所以这里不会给出非常详细的说明。
因为要搭建一个博客服务，所以这里配置的域名为blog.xpleaf.org，操作过程如下：
1.最小化配置文件
[root@leaf ~]# cd /application/nginx/conf/
[root@leaf conf]# wc -l nginx.conf
117 nginx.conf
[root@leaf conf]# wc -l nginx.conf.default
117 nginx.conf.default
[root@leaf conf]# egrep -v "#|^$" nginx.conf.default >nginx.conf
[root@leaf conf]# wc -l nginx.conf
22 nginx.conf
[root@leaf conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}2.修改配置文件
修改nginx.conf，并且增加配置文件extra/blog.conf，如下：
[root@leaf conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
include extra/blog.conf;
}
[root@leaf conf]# cat extra/blog.conf
server {
listen 80;
server_name blog.xpleaf.org;
location / {
root html/blog;
index index.html index.htm;
}
}3.创建域名对应的站点目录及文件
[root@leaf conf]# cd ../html/ [root@leaf html]# mkdir blog [root@leaf html]# echo "This page is: blog.xpleaf.org">blog/index.html [root@leaf html]# cat blog/index.html This page is: blog.xpleaf.org
4.重启Nginx服务
[root@leaf html]# /application/nginx/sbin/nginx -t nginx: the configuration file /application/nginx-1.6.3//conf/nginx.conf syntax is ok [root@leaf html]# /application/nginx/sbin/nginx -s reload # 平滑重启
5.CentOS 6.5上进行测试
先修改/etc/hosts文件：
[root@leaf html]# echo "127.0.0.1 blog.xpleaf.org" >>/etc/hosts [root@leaf html]# tail -1 /etc/hosts 127.0.0.1 blog.xpleaf.org
再使用命令测试：
[root@leaf html]# curl blog.xpleaf.org This page is: blog.xpleaf.org [root@leaf html]# wget blog.xpleaf.org --2017-03-04 04:58:42-- http://blog.xpleaf.org/ 正在解析主机 blog.xpleaf.org... 127.0.0.1 正在连接 blog.xpleaf.org|127.0.0.1|:80... 已连接。 已发出 HTTP 请求，正在等待回应... 200 OK 长度：30 [text/html] 正在保存至: “index.html.1” 100%[====================================>] 30 --.-K/s in 0s 2017-03-04 04:58:42 (2.14 MB/s) - 已保存 “index.html.1” [30/30])
6.宿主机Windows 7上进行测试
同样是先修改hosts文件，Windows 7的hosts文件在C:\Windows\System32\drivers\etc，同样添加下面一行：
10.0.0.101 blog.xpleaf.org
使用浏览器访问blog.xpleaf.org，如下：
那么到这里，LNMP的环境中，Nginx的安装已经完成了，你是否安装成功了呢？
3.LNMP环境搭建：MySQL安装与基本安全优化
这里采用二进制安装的方式来安装MySQL，安装的版本为：MySQL Server 5.5.54，可以在https://dev.mysql.com/downloads/mysql/5.5.html#downloads中下载。
MySQL安装完成后会做一些基本的安全优化。
（1）MySQL安装
1.创建MySQL用户的账号
[root@leaf ~]# groupadd mysql [root@leaf ~]# useradd -s /sbin/nologin -g mysql -M mysql [root@leaf ~]# tail -1 /etc/passwd mysql:x:501:501::/home/mysql:/sbin/nologin
2.下载MySQL
可以使用wget来进行安装，也可以先下载到Windows 7上，然后使用SecureCRT，在CentOS上使用rz命令（需要使用yum install -y lrzsz命令安装）上传到我们的CentOS上，其实不管哪一种方式，只要有方式获取到该安装包就可以了，下面使用的是wget获取安装包的方式：
[root@leaf tools]# wget https://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.54-linux2.6-x86_64.tar.gz [root@leaf tools]# ls -l mysql-5.5.54-linux2.6-x86_64.tar.gz -rw-r--r--. 1 root root 185911232 3月 3 13:34 mysql-5.5.54-linux2.6-x86_64.tar.gz
3.解压并移到指定目录
[root@leaf tools]# tar xf mysql-5.5.54-linux2.6-x86_64.tar.gz [root@leaf tools]# mv mysql-5.5.54-linux2.6-x86_64 /application/mysql-5.5.54 [root@leaf tools]# ln -s /application/mysql-5.5.54/ /application/mysql [root@leaf tools]# ls -l /application/ 总用量 8 lrwxrwxrwx. 1 root root 26 3月 4 06:43 mysql -> /application/mysql-5.5.54/ drwxr-xr-x. 13 root root 4096 3月 4 06:42 mysql-5.5.54 lrwxrwxrwx. 1 root root 25 3月 4 04:28 nginx -> /application/nginx-1.6.3/ drwxr-xr-x. 11 root root 4096 3月 4 04:30 nginx-1.6.3
4.初始化MySQL配置文件
[root@leaf mysql]# cp support-files/my-small.cnf /etc/my.cnf cp：是否覆盖"/etc/my.cnf"？ y
5.初始化MySQL数据库文件
[root@leaf mysql]# mkdir -p /application/mysql/data/ [root@leaf mysql]# chown -R mysql.mysql /application/mysql [root@leaf mysql]# yum install -y libaio # 安装MySQL依赖函数库，否则下面的初始化会失败 [root@leaf mysql]# /application/mysql/scripts/mysql_install_db --basedir=/application/mysql --datadir=/application/mysql/data --user=mysql ...... # 输出结果可以看到两个OK，即说明初始化成功 [root@leaf mysql]# echo $? # 或者通过该命令，输出为0，即说明上一个步骤的命令执行成功 0 # 上面之后可以看到/application/mysql/data/目录下生成的数据库文件
6.配置并启动MySQL数据库
#（1）设置MySQL启动脚本 [root@leaf mysql]# cp support-files/mysql.server /etc/init.d/mysqld [root@leaf mysql]# chmod +x /etc/init.d/mysqld [root@leaf mysql]# ls -l /etc/init.d/mysqld -rwxr-xr-x. 1 root root 10875 3月 4 06:56 /etc/init.d/mysqld #（2）替换启动脚本中MySQL默认的安装路径/usr/local/mysql [root@leaf mysql]# sed -i 's#/usr/local/mysql#/application/mysql#g' /application/mysql/bin/mysqld_safe /etc/init.d/mysqld #（3）启动MySQL数据库 [root@leaf mysql]# /etc/init.d/mysqld start Starting MySQL.Logging to '/application/mysql/data/leaf.err'. ... SUCCESS! #（4）检查MySQL数据库是否启动 [root@leaf mysql]# netstat -lntup | grep mysql tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 4400/mysqld #（5）查看日志 [root@leaf mysql]# tail -10 /application/mysql/data/leaf.err InnoDB: Creating foreign key constraint system tables InnoDB: Foreign key constraint system tables created 170304 7:00:28 InnoDB: Waiting for the background threads to start 170304 7:00:29 InnoDB: 5.5.54 started; log sequence number 0 170304 7:00:29 [Note] Server hostname (bind-address): '0.0.0.0'; port: 3306 170304 7:00:29 [Note] - '0.0.0.0' resolves to '0.0.0.0'; 170304 7:00:29 [Note] Server socket created on IP: '0.0.0.0'. 170304 7:00:29 [Note] Event Scheduler: Loaded 0 events 170304 7:00:29 [Note] /application/mysql/bin/mysqld: ready for connections.

（2）MySQL基本安全优化
1.为root用户设置密码
[root@leaf mysql]# mysqladmin -u root password '123456'
2.清理无用的MySQL用户及数据库
[root@leaf mysql]# mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.

到此为此，MySQL也安装完成了！
4.LNMP环境搭建：PHP（FastCGI方式）安装、配置与启动
（1）安装PHP依赖函数库
1.安装lib库
需要安装的lib库如下：
zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel
其中除了libiconv库外，其他都可以通过yum的方式进行安装，安装如下：
# 使用yum安装除libiconv-devel之外的其它lib库 [root@leaf mysql]# yum install -y zlib-devel libxml2-devel libjpeg-devel libjpeg-turbo-devel libiconv-devel freetype-devel libpng-devel gd-devel libcurl-devel libxslt-devel # 编译安装libiconv-devel [root@leaf tools]# wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz [root@leaf tools]# tar zxf libiconv-1.14.tar.gz [root@leaf tools]# cd libiconv-1.14 [root@leaf libiconv-1.14]# ./configure --prefix=/usr/local/libiconv [root@leaf libiconv-1.14]# make [root@leaf libiconv-1.14]# make install
2.安装libmcrypt库
[root@leaf ~]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo [root@leaf ~]# yum install -y libmcrypt-devel
3.安装mhash加密扩展库
[root@leaf ~]# yum install -y mhash
4.安装mcrypt加密扩展库
[root@leaf ~]# yum install -y mcrypt
（2）安装PHP
使用的PHP版本号为5.3.27，如下：
1.下载PHP安装包
[root@leaf tools]# wget http://cn2.php.net/get/php-5.3.27.tar.gz/from/this/mirror [root@leaf tools]# mv mirror php-5.3.27.tar.gz [root@leaf tools]# ls -l php-5.3.27.tar.gz -rw-r--r--. 1 root root 15008639 1月 21 2015 php-5.3.27.tar.gz
2.解压缩
[root@leaf tools]# tar zxf php-5.3.27.tar.gz [root@leaf tools]# cd php-5.3.27 [root@leaf php-5.3.27]# pwd /root/tools/php-5.3.27
3.配置PHP的安装参数
配置项非常多，如下：
./configure \ --prefix=/application/php5.3.27 \ --with-mysql=/application/mysql \ --with-iconv-dir=/usr/local/libiconv \ --with-freetype-dir \ --with-jpeg-dir \ --with-png-dir \ --with-zlib \ --with-libxml-dir=/usr \ --enable-xml \ --disable-rpath \ --enable-safe-mode \ --enable-bcmath \ --enable-shmop \ --enable-sysvsem \ --enable-inline-optimization \ --with-curl \ --with-curlwrappers \ --enable-mbregex \ --enable-fpm \ --enable-mbstring \ --with-mcrypt \ --with-gd \ --enable-gd-native-ttf \ --with-openssl \ --with-mhash \ --enable-pcntl \ --enable-sockets \ --with-xmlrpc \ --enable-zip \ --enable-soap \ --enable-short-tags \ --enable-zend-multibyte \ --enable-static \ --with-xsl \ --with-fpm-user=nginx \ --with-fpm-group=nginx \ --enable-ftp
可以将其直接复制到命令行进行配置，这样就可以减少出错的概率：
[root@leaf php-5.3.27]# ./configure \ > --prefix=/application/php5.3.27 \ > --with-mysql=/application/mysql \ > --with-iconv-dir=/usr/local/libiconv \ > --with-freetype-dir \ > --with-jpeg-dir \ > --with-png-dir \ > --with-zlib \ > --with-libxml-dir=/usr \ > --enable-xml \ > --disable-rpath \ > --enable-safe-mode \ > --enable-bcmath \ > --enable-shmop \ > --enable-sysvsem \ > --enable-inline-optimization \ > --with-curl \ > --with-curlwrappers \ > --enable-mbregex \ > --enable-fpm \ > --enable-mbstring \ > --with-mcrypt \ > --with-gd \ > --enable-gd-native-ttf \ > --with-openssl \ > --with-mhash \ > --enable-pcntl \ > --enable-sockets \ > --with-xmlrpc \ > --enable-zip \ > --enable-soap \ > --enable-short-tags \ > --enable-zend-multibyte \ > --enable-static \ > --with-xsl \ > --with-fpm-user=nginx \ > --with-fpm-group=nginx \ > --enable-ftp ...... +--------------------------------------------------------------------+ | License: | | This software is subject to the PHP License, available in this | | distribution in the file LICENSE. By continuing this installation | | process, you are bound by the terms of this license agreement. | | If you do not agree with the terms of this license, you must abort | | the installation process at this point. | +--------------------------------------------------------------------+ Thank you for using PHP.
4.编译PHP
[root@leaf php-5.3.27]# ln -s /application/mysql/lib/libmysqlclient.so.18 /usr/lib64/ [root@leaf php-5.3.27]# touch ext/phar/phar.phar [root@leaf php-5.3.27]# make ...... [root@leaf php-5.3.27]# echo $? 0
5.安装PHP
[root@leaf php-5.3.27]# make install /root/tools/php-5.3.27/build/shtool install -c ext/phar/phar.phar /application/php5.3.27/bin ln -s -f /application/php5.3.27/bin/phar.phar /application/php5.3.27/bin/phar Installing PDO headers: /application/php5.3.27/include/php/ext/pdo/ ...... [root@leaf php-5.3.27]# echo $? 0
（3）配置与启动PHP
1.设置PHP安装目录软链接
[root@leaf php-5.3.27]# ln -s /application/php5.3.27/ /application/php [root@leaf php-5.3.27]# ls -l /application/php lrwxrwxrwx. 1 root root 23 3月 4 08:59 /application/php -> /application/php5.3.27/
2.拷贝PHP配置文件到PHP默认目录
[root@leaf php-5.3.27]# cp php.ini-production /application/php/lib/php.ini [root@leaf php-5.3.27]# ls -l /application/php/lib/php.ini -rw-r--r--. 1 root root 69627 3月 4 09:00 /application/php/lib/php.ini
3.配置php-fpm.conf文件
[root@leaf php-5.3.27]# cd /application/php/etc/ [root@leaf etc]# ls pear.conf php-fpm.conf.default [root@leaf etc]# cp php-fpm.conf.default php-fpm.conf
4.启动PHP服务php-fpm
[root@leaf etc]# /application/php/sbin/php-fpm
5.检查启动进程与侦听端口号
[root@leaf etc]# ps -ef | grep php-fpm root 129256 1 0 09:05 ? 00:00:00 php-fpm: master process (/application/php5.3.27/etc/php-fpm.conf) nginx 129257 129256 0 09:05 ? 00:00:00 php-fpm: pool www nginx 129258 129256 0 09:05 ? 00:00:00 php-fpm: pool www root 129260 13743 0 09:06 pts/1 00:00:00 grep php-fpm [root@leaf etc]# netstat -lntup | grep 9000 tcp 0 0 127.0.0.1:9000 0.0.0.0:* LISTEN 129256/php-fpm
至此，PHP也安装完成了！LNMP的各个组件都安装好了，下面就要对LNMP环境进行测试了。
5.LNMP环境测试
（1）配置Nginx支持PHP程序请求访问
1.查看当前Nginx配置
[root@leaf etc]# cd /application/nginx/conf/
[root@leaf conf]# cat nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
include extra/blog.conf;
}
[root@leaf conf]# cat extra/blog.conf
server {
listen 80;
server_name blog.xpleaf.org;
location / {
root html/blog;
index index.html index.htm;
}
}2.修改extra/blog.conf配置文件
[root@leaf conf]# cat extra/blog.conf
server {
listen 80;
server_name blog.xpleaf.org;
location / {
root html/blog;
index index.html index.htm;
}
location ~ .*\.(php|php5)?$ {
root html/blog;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
}3.检查并启动Nginx
[root@leaf conf]# /application/nginx/sbin/nginx -t nginx: the configuration file /application/nginx-1.6.3//conf/nginx.conf syntax is ok nginx: configuration file /application/nginx-1.6.3//conf/nginx.conf test is successful [root@leaf conf]# /application/nginx/sbin/nginx -s reload
（2）测试LNMP环境是否生效
1.配置域名站点目录
[root@leaf conf]# cd /application/nginx/html/blog/ [root@leaf blog]# echo "<?php phpinfo(); ?>" >test_info.php [root@leaf blog]# cat test_info.php <?php phpinfo(); ?>
2.宿主机上在浏览器中输入地址http://blog.xpleaf.org/test_info.php进行访问
（3）测试PHP连接MySQL是否正常
1.编辑text_mysql.php
[root@leaf blog]# cat test_mysql.php
<?php
$link_id=mysql_connect('localhost', 'root', '123456');
if($link_id){
echo "mysql succesful by xpleaf !";
}else{
echo mysql_error();
}
?>2.宿主机上在浏览器中输入地址http://blog.xpleaf.org/test_mysql.php进行访问
至此，LNMP环境搭建与测试完成了，下面就可以开始部署WordPress了！
6.部署WordPress
（1）MySQL数据库准备
1.登陆mysql
[root@leaf blog]# mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 5 Server version: 5.5.54 MySQL Community Server (GPL) Copyright (c) 2000, 2016, Oracle and/or its affiliates. All rights reserved. Oracle is a registered trademark of Oracle Corporation and/or its affiliates. Other names may be trademarks of their respective owners. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. mysql>
2.创建数据库wordpress
mysql> create database wordpress; Query OK, 1 row affected (0.32 sec) mysql> show databases; +--------------------+ | Database | +--------------------+ | information_schema | | mysql | | performance_schema | | wordpress | +--------------------+ 4 rows in set (0.00 sec)
3.创建wordpress blog管理用户
mysql> grant all on wordpress.* to wordpress@'localhost' identified by '123456'; Query OK, 0 rows affected (0.08 sec) mysql> show grants for wordpress@'localhost'; +------------------------------------------------------------------------------------------------------------------+ | Grants for wordpress@localhost | +------------------------------------------------------------------------------------------------------------------+ | GRANT USAGE ON *.* TO 'wordpress'@'localhost' IDENTIFIED BY PASSWORD '*6BB4837EB74329105EE4568DDA7DC67ED2CA2AD9' | | GRANT ALL PRIVILEGES ON `wordpress`.* TO 'wordpress'@'localhost' | +------------------------------------------------------------------------------------------------------------------+ 2 rows in set (0.00 sec)
4.刷新MySQL用户权限
mysql> flush privileges; Query OK, 0 rows affected (0.31 sec)
5.检查MySQL登录用户
mysql> select user,host from mysql.user; +-----------+-----------+ | user | host | +-----------+-----------+ | root | 127.0.0.1 | | root | localhost | | wordpress | localhost | +-----------+-----------+ 3 rows in set (0.00 sec)
（2）Nginx配置准备
1.修改blog.conf配置文件
[root@leaf conf]# cat extra/blog.conf
server {
listen 80;
server_name blog.xpleaf.org;
location / {
root html/blog;
index index.php index.html index.htm;
}
location ~ .*\.(php|php5)?$ {
root html/blog;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
}
# 相比前面的配置文件，只是在/下添加了index.php
# 不过需要注意的是，index.php一定要放在index关键字之后，
# 这样访问blog.xpleaf.org时，才会打开我们的WordPress页面2.重启Nginx服务
[root@leaf conf]# /application/nginx/sbin/nginx -s reload
（3）配置WordPress
1.获取WordPress安装包
[root@leaf tools]# wget https://cn.wordpress.org/wordpress-4.7.3-zh_CN.tar.gz [root@leaf tools]# ls -lh wordpress-4.7.2-zh_CN.tar.gz -rw-r--r--. 1 root root 8.1M 1月 28 08:53 wordpress-4.7.2-zh_CN.tar.gz
2.解压缩与配置站点目录
[root@leaf tools]# cp wordpress-4.7.2-zh_CN.tar.gz /application/nginx/html/blog/ [root@leaf tools]# cd /application/nginx/html/blog/ [root@leaf blog]# tar zxf wordpress-4.7.2-zh_CN.tar.gz [root@leaf blog]# ls index.html test_mysql.php wordpress-4.7.2-zh_CN.tar.gz test_info.php wordpress [root@leaf blog]# rm -rf test_* wordpress-4.7.2-zh_CN.tar.gz # 删除无用的文件 [root@leaf blog]# ls index.html wordpress [root@leaf blog]# mv wordpress/* ./ # 将wordpress程序移到当前blog目录下 [root@leaf blog]# ls index.html wp-admin wp-includes wp-signup.php index.php wp-blog-header.php wp-links-opml.php wp-trackback.php license.txt wp-comments-post.php wp-load.php xmlrpc.php readme.html wp-config-sample.php wp-login.php wordpress wp-content wp-mail.php wp-activate.php wp-cron.php wp-settings.php [root@leaf blog]# ls -l 总用量 196 -rw-r--r--. 1 root root 30 3月 4 04:54 index.html -rw-r--r--. 1 nobody 65534 418 9月 25 2013 index.php -rw-r--r--. 1 nobody 65534 19935 1月 3 02:51 license.txt -rw-r--r--. 1 nobody 65534 6956 1月 28 08:53 readme.html drwxr-xr-x. 2 nobody 65534 4096 3月 4 09:50 wordpress ......
3.对blog下所有文件授予nginx用户和组的权限
[root@leaf blog]# chown -R nginx.nginx ../blog/ [root@leaf blog]# ls -l 总用量 196 -rw-r--r--. 1 nginx nginx 30 3月 4 04:54 index.html -rw-r--r--. 1 nginx nginx 418 9月 25 2013 index.php -rw-r--r--. 1 nginx nginx 19935 1月 3 02:51 license.txt -rw-r--r--. 1 nginx nginx 6956 1月 28 08:53 readme.html drwxr-xr-x. 2 nginx nginx 4096 3月 4 09:50 wordpress ......

7.下一步要做什么
可以在云主机上，如腾讯云或者阿里云上搭建LNMP环境，再部署一个WordPress博客程序，为了达到域名访问的效果，可以购买一个域名，然后自己搭建DNS服务器，这会是非常不错的体验！
接下来就可以考虑对LNMP进行优化了。
