centos将nginx加入到系统服务并开机自启动项的方法

centos（linux）系统下将nginx服务加入到系统服务并加入到开机自启动的方法。先来看下本人安装的效果吧，截图如下！

具体的方法如下：

一。首先写一个shell脚本，脚本名称：nginx

vim /etc/init.d/nginx

输入如下内容：

#!/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
nginxd=/opt/nginx/sbin/nginx
nginx_config=/opt/nginx/conf/nginx.conf
nginx_pid=/var/run/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 /var/run/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 $prog
        RETVAL=$?
        ;;
help)
        echo "感谢www.phpernote.com提供的教程！"
        ;;
*)
        echo $"Usage: $prog {start|stop|restart|reload|status|help}"
        exit 1
esac
exit $RETVAL

# 使用说明

# service nginx start 启动 nginx

# service nginx stop 停止 nginx

# service nginx reload 重新加载 nginx

# service nginx restart 先停止 nginx，再启动 nginx

# service nginx status 查看 nginx 服务状态

# service nginx help 查看 nginx 帮助

注意：以上代码中的如下三行代码需要替换为你自己的相关信息，nginxd即nginx启动文件的位置，可通过which查找，nginx_config即nginx配置文件的位置，可通过

find / -name nginx.conf

命令查找。

nginxd=/opt/nginx/sbin/nginx nginx_config=/opt/nginx/conf/nginx.conf nginx_pid=/var/run/nginx.pid

nginx_pid一般不用修改。

二。将以上shell脚本保存，并执行下列命令将该文件设置为可执行权限：

chmod +x /etc/rc.d/init.d/nginx 或者 chmod 755 /etc/init.d/nginx

三。将nginx加入到系统服务中

chkconfig --add nginx 或者 chkconfig nginx on

网上还有其他的方法，这里就不一一记录了。
