解压：tar -zxvf nginx-1.16.0.tar.gz
进去：cd nginx-1.16.0

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
PS：经常粘贴前两行贴不全，小心检查。
