linux下安装nginx后开机启动篇

众所周知nginx安装后需要手动去启动，每次开机之后都要执行nginx的启动命令很蛋疼。那么我们来让nginx开机启动吧

1、先創建一個nginx文件把

[root@localhost ~]# vi /etc/init.d/nginx   #这个命令可以直接创建一个nginx文件

 2、把下面的代碼拷貝到剛剛創建的nginx文件里

#!/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: /var/run/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

注意：紅色加粗的路徑改為自己的路徑

3、給nginx文件權限

[root@localhost ~]# chmod a+x /etc/init.d/nginx

 4、這一部是很重要的一步。把nginx加進開機確定的服務中

[root@localhost ~]# chkconfig --add nginx
[root@localhost ~]# chkconfig --level 35 nginx on   #启动nginx的级别

 也可以直接把nginx的启动项加到开机执行脚本中

[root@localhost ~]# vi /etc/rc.local  #打开local文件，在后面加入代码：/etc/init.d/nginx start

 好了，重启下linux试试效果吧

[root@localhost ~]# reboot  #重启linux命令

 刷新浏览器是不是可以了

以后就可以通过以下命令来操作nginx
启动：service nginx start
关闭：service nginx stop 
重起：service nginx restart
