nginx的编译安装

1、安装编译环境
yum -y install gcc gcc-c++ make ncurses ncurses-devel

创新互联建站是一家专注于网站制作、成都网站设计和乐山服务器托管的网络公司，有着丰富的建站经验和案例。

2、安装pcre软件包（使nginx支持http rewrite模块）
yum install -y pcre pcre-devel

3、安装openssl-devel（使nginx支持ssl）
yum install -y openssl openssl-devel

4、安装zlib
yum install -y zlib zlib-devel

5、创建用户nginx

groupadd nginx
useradd  -r -g nginx -s /sbin/nologin nginx

6、安装nginx

[root@localhost ~]# wget http://nginx.org/download/nginx-1.16.0.tar.gz
[root@localhost ~]# tar xzf nginx-1.16.0.tar.gz -C /usr/local/
