搭建完全分离式LNMP平台的简单案例
案例拓扑图安装配置nginx服务器
编译安装nginx时，需要事先安装 开发包组"Development Tools"和"Server Platform Development"，同时还需专门安装pcre-devel包。
1

3
# yum -y groupinstall "Development Tools"
# yum -y groupinstall "Server Platform Development"
# yum -y install pcre-devel
首先添加nginx用户组和nginx用户
1
2
# groupadd -r nginx
# useradd -g nginx -r nginx
创建编译安装是所需要的目录
1
# mkdir -pv /var/tmp/nginx/client

为此脚本赋予执行权限
1
# chmod +x /etc/rc.d/init.d/nginx
将nginx服务添加至服务管理列表，并让其开机自动启动
1
2
# chkconfig --add nginx
# chkconfig nginx on
编辑配置文件/etc/nginx/nginx.conf，在server段内添加如下内容
