#重新配置后的问题：
configure:error: Cannot find MySQL header files under /application/mysql.
Note that theMySQL client library is not bundled anymore!
#不管怎么变更该数据库的路径，还是编译通还过
解决办法就是:
#mkdir /usr/lib/msyql –p
#cp /usr/lib64/mysql/* /usr/lib/mysql/
然后进行./configure即可，如果服务器没有/usr/lib/mysql/ 目录，则在/usr/lib/目录下创建mysql目录即可

[root@Cactiphp-5.3.27]# cp php.ini-production /application/php/lib/php.ini #拷贝php的配置文件到PHP默认目录
在linux上编译安装PHP时，为什么php/etc/目录下没有找到php-fpm.conf.default这个文件?
解答：原因在拷贝配置文件执行时，有部分代码没有执行。
注意：当执行一大块代码结束后并没有报错，但没有执行的配置语句会重新显示出来。

[root@Cactietc]# cp php-fpm.conf.default php-fpm.conf
启动PHP服务php-fpm:
[root@Cactietc]# /application/php/sbin/php-fpm
检查php服务php-fpm的进程及启动端口的情况：
[root@Cactietc]# ps -ef|grep php-fpm
root 23321 1 0 17:43 ? 00:00:00 php-fpm: master process(/application/php5.3.27/etc/php-fpm.conf)

配置Nginx支持PHP程序请求访问
#vi nginx.conf #修改配置文件
location~.*\.(php|php5)?$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
#检查并启动Nginx
[root@Cacticonf]# ../sbin/nginx -t
nginx: theconfiguration file /application/nginx/conf/nginx.conf syntax is ok
nginx:configuration file /application/nginx/conf/nginx.conf test is successful
[root@Cacticonf]# ../sbin/nginx -s reload
测试LNMP环境生效的情况：
[root@Cactihtml]# echo "<?php phpinfo(); ?>" >test_info.php
[root@Cactihtml]# cat test_info.php
<?phpphpinfo(); ?>
PHP连接MySQL的情况进行测试：
[root@Cactihtml]# vi test_mysql.php
<?php
$link_id=mysql_connect('localhost','root','*****')or mysql_error();
if($link_id){
echo "mysql successful byskyboy!";
}else{
echo mysql_error();
}
?>
下面部署一个wordpress程序服务：
1.先创建一个专用的数据库WordPress
[root@Cactihtml]# mysql -uroot –p
mysql>create database wordpress;
Query OK, 1row affected (0.00 sec)
mysql>show databases like 'wordpress';
+----------------------+
| Database(wordpress) |
+----------------------+
|wordpress |
+----------------------+
1 row in set(0.00 sec)
Nginx及PHP环境配置准备：
location / {
root html;
index index.php index.html index.htm;
}
location ~.*\.(php|php5)?$ {
root html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
include fastcgi.conf;
}
[root@Cactihtml]# wget https://tw.wordpress.org/wordpress-4.8-zh_TW.tar.gz
[root@Cactihtml]# tar xf wordpress-4.8-zh_TW.tar.gz
[root@Cactihtml]# mkdir blog
[root@Cactihtml]# mv wordpress blog/
[root@Cactihtml]# chown -R nginx.nginx blog
测试情况：浏览器显示Filenot found.
解答：原因是解析不到程序，建设直接放到html目录下，避免发生找不到程序的问题。
[root@Cactiwordpress]# cp wp-config-sample.php wp-config.php
[root@Cactiwordpress]# vi wp-config.php #配置数据库名、用户名和密码即可
配置成功。
以上是通过一台服务器架构LNMP;
下面通过两台服务器架设LNMP,也很简单：
.8服务器: 做Nginx服务器，将wordpress放到nginx的html目录下，配置wp-config.php文件。
/** WordPress数据库的名称 */
define('DB_NAME', 'wordpress');
/** MySQL数据库用户名 */
define('DB_USER', '***');
/** MySQL数据库密码 */
define('DB_PASSWORD', '*****');
/** MySQL主机 */
define('DB_HOST', '.9服务器IP');
.9服务器:做Mysql服务器，创建wordpress数据库。
技巧：当服务器每次重启的时候需要nginx、php-fpm服务自动启动。
#vi /etc/rc.local #在默尾增加两条命令
/application/nginx/sbin/nginx
/application/php/sbin/php-fpm
运行结果：http://117.40.239.8:8080/wordpress
