今天就跟大家聊聊有关利用shell脚本怎么部署LNMP架构,可能很多人都不太了解,为了让大家更加了解,小编给大家总结了以下内容,希望大家根据这篇文章可以有所收获。
LNMP架构介绍
LNMP:Linux系统下Nginx+MySQL+PHP这种网站服务器架构。Nginx是一个高性能的HTTP和反向代理服务器,也是一个IMAP/POP3/SMTP代理服务器。Mysql是一个小型关系型数据库管理系统。PHP是一种在服务器端执行的嵌入HTML文档的脚本语言。
原理:浏览器发送http request请求到服务器(Nginx),服务器响应并处理web请求,将一些静态资源(CSS,图片,视频等)保存服务器上,然后将php脚本通过接口传输协议(网关协议)PHP-FCGI(fast-cgi)传输给PHP-FPM(进程管理程序),PHP-FPM不做处理,然后PHP-FPM调用PHP解析器进程,PHP解析器解析php脚本信息。PHP解析器进程可以启动多个,进行并发执行。然后将解析后的脚本返回到PHP-FPM,PHP-FPM再通过fast-cgi的形式将脚本信息传送给Nginx.服务器再通过Http response的形式传送给浏览器。浏览器再进行解析与渲染然后进行呈现。
下面给大家介绍下使用shell脚本一键部署LNMP架构的方法,脚本如下所示:
#/bin/bash ##将需要的安装包传到/opt目录下,并关闭防火墙 systemctl stop firewalld systemctl disable firewalld &>/dev/null setenforce 0 ###############Nginx############### ##先挂载,再安装依赖包 df -h | grep /mnt if [ $? -ne 0 ];then mount /dev/cdrom /mnt &>/dev/null fi yum -y install pcre-devel zlib-devel gcc gcc-c++ make ##创建运行用户、组(Nginx服务程序默认以nobody身份运行,建议为其创建专门的用户账号,以便更准确的控制其访问权限) useradd -M -s /sbin/nologin nginx ##编译安装 cd /opt tar zxvf nginx-1.12.0.tar.gz cd nginx-1.12.0/ ./configure \ --prefix=/usr/local/nginx \ --user=nginx \ --group=nginx \ --with-http_stub_status_module make -j 2 && make install ##优化配置文件路径,并把nginx服务的可执行程序文件放入路径环境变量的目录中便于系统识别 ln -s /usr/local/nginx/sbin/* /usr/local/sbin ##添加Nginx系统服务 cat > /lib/systemd/system/nginx.service <<EOF [Unit] Description=nginx After=network.target
