1. 编译源码安装Nginx

• nginx下载地址：http://nginx.org/en/download.html
• 本文使用：nginx-1.16.1

1. 安装依赖软件

   yum -y install gcc gcc-c++ pcre pcre-devel openssl openssl-devel zlib zlib-devel
   

2. 安装nginx

• 解压进入nginx目录

  tar -zxvf nginx-1.16.1.tar.gz

• 安装nginx

  [root@magic nginx-1.16.1]# ./configure
  [root@magic nginx-1.16.1]# make && make install
  

• nginx安装到了/usr/local/nginx目录下

3. 启动nginx

   [root@magic ~]# /usr/local/nginx/sbin/nginx 
   
   # 查看启动进程
   [root@magic ~]# ps -ef | grep nginx
   root      7950     1  0 16:11 ?        00:00:00 nginx: master process /usr/local/nginx/sbin/nginx
   nobody    7951  7950  0 16:11 ?        00:00:00 nginx: worker process
   

4. 访问页面

   http://hostname:80/

   

5. nginx启停命令

   # 启动
   /usr/local/nginx/sbin/nginx
   # 停止
   /usr/local/nginx/sbin/nginx -s stop
   # 重新加载配置(热加载)，并非重启服务
   /usr/local/nginx/sbin/nginx -s reload
   

2. yum安装Nginx

官网地址：http://nginx.org/en/linux_packages.html#RHEL-CentOS

• 安装yum-utils

  sudo yum install yum-utils -y
  

• 创建/etc/yum.repos.d/nginx.repo文件

  [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
  

• 重新生成yum缓存

  yum makecache fast
  

• 安装Nginx

  # 默认安装的是nginx最新稳定版
  # 如果想安装最新的快照版，执行以下命令
  # sudo yum-config-manager --enable nginx-mainline
  
  # 通常我们安装稳定版
  sudo yum install nginx -y
  

• 启停

  systemctl start nginx
  systemctl stop nginx
  

• 配置文件目录：/etc/nginx/nginx.conf
