安装nginx

1.yum 安装（默认情况下使用yum安装的nginx包含ssl模块）

    官方 yum 源链接 http://nginx.org/en/linux_packages.html#RHEL-CentOS
    
    vim /etc/yum.repos.d/nginx.repo

[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

    
    yum-config-manager --enable nginx-stable
    
    yum install nginx

2.源码编译安装

下载源码包  http://nginx.org/en/download.html  下载稳定版本

Mainline version：Mainline 是 Nginx 目前主力在做的版本，可以说是开发版
Stable version：最新稳定版，生产环境上建议使用的版本
Legacy versions：遗留的老版本的稳定版

下载命令
wget http://nginx.org/download/nginx-1.22.0.tar.gz

解压缩
tar -zxvf nginx-1.22.0.tar.gz
    
 ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre
 
 make && make install
 
 ln -s /usr/local/nginx/conf  /etc/nginx

配置服务

vim /lib/systemd/system/nginx.service

[Unit]
Description=nginx
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s quit
PrivateTmp=true

[Install]
WantedBy=multi-user.target


软连接etc目录
ln -s /usr/local/nginx/conf /etc/nginx   

systemctl status nginx
systemctl reload nginx
systemctl start nginx

开机启动
systemctl enable nginx

添加用户
groupadd www
useradd -g www -s /sbin/nologin www

配置文件

/etc/nginx/nginx.conf
