下载：wget https://nginx.org/download/nginx-1.16.0.tar.gz

安装

移走：mv ./nginx-1.16.0.tar.gz /usr/local/

解压：tar -zxvf nginx-1.16.0.tar.gz

进去：cd nginx-1.16.0

配置：./configure --with-http_stub_status_module --with-http_ssl_module

安装：make && make install

配置

打开配置文件：vim /usr/local/nginx/conf/nginx.conf

一个监听是一个server{....}段落，里面默认的server代码块可以删掉。

当你在你的域名控制台（阿里云或腾讯云或百度云等等）中设置域名解析成当前服务器IP时，你就可以在这里配置域名监听。

比如下面这段：

    server {
        listen       80;
        server_name  www.abc.com abc.com;
        root /www/abc;
        location / {
           index.html;
        }
     }

当浏览器访问 www.abc.com时，由于域名解析指向当前服务器，所以网络请求会发往当前服务器的80端口，nginx监听到请求后，会去找到root指定的地址 也就是/www/abc目录，将目录中的index.html返回给请求方，此时浏览器收到返回，解析标签，展示在页面上。

命令

编写服务脚本：vim /etc/init.d/nginx

粘贴以下代码：

#!/bin/bash
# nginx Startup script for the Nginx HTTP Server
# it is v.0.0.2 version.
# chkconfig: - 85 15
# description: Nginx is a high-performance web and proxy server.
#              It has a lot of features, but it's not for everyone.
# processname: nginx
# pidfile: /usr/local/nginx/logs/nginx.pid
# config: /usr/local/nginx/conf/nginx.conf
nginxd=/usr/local/nginx/sbin/nginx
nginx_config=/usr/local/nginx/conf/nginx.conf
nginx_pid=/usr/local/nginx/logs/nginx.pid
RETVAL=0
prog="nginx"
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ "${NETWORKING}" = "no" ] && exit 0
[ -x $nginxd ] || exit 0
# Start nginx daemons functions.
start() {
if [ -e $nginx_pid ];then
   echo "nginx already running...."
   exit 1
fi
   echo -n $"Starting $prog: "
   daemon $nginxd -c ${nginx_config}
   RETVAL=$?
   echo
   [ $RETVAL = 0 ] && touch /var/lock/subsys/nginx
   return $RETVAL
}
# Stop nginx daemons functions.
stop() {
        echo -n $"Stopping $prog: "
        killproc $nginxd
        RETVAL=$?
        echo
        [ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /usr/local/nginx/logs/nginx.pid
}
# reload nginx service functions.
reload() {
    echo -n $"Reloading $prog: "
    #kill -HUP `cat ${nginx_pid}`
    killproc $nginxd -HUP
    RETVAL=$?
    echo
}
# See how we were called.
case "$1" in
start)
        start
        ;;
stop)
        stop
        ;;
reload)
        reload
        ;;
restart)
        stop
        start
        ;;
status)
        status $prog
        RETVAL=$?
        ;;
*)
        echo $"Usage: $prog {start|stop|restart|reload|status|help}"
        exit 1
esac
exit $RETVAL
