CentOS下设置nginx开机自动启动和chkconfig管理

vim /etc/init.d/nginx   #在linux系统的/etc/init.d/目录下创建nginx文件

在脚本中添加如下命令：

#!/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   #修改成nginx安装路径的执行程序的路径。
nginx_config=/usr/local/nginx/conf/nginx.conf  #修改成配置文件的路径。
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 $prog
        RETVAL=$?
        ;;
*)
        echo $"Usage: $prog {start|stop|restart|reload|status|help}"
        exit 1
esac
exit $RETVAL

 
chmod a+x /etc/init.d/nginx  #设置文件的执行权限

然后，就可以通过该脚本对nginx服务进行管理了：

/etc/init.d/nginx start
/etc/init.d/nginx stop

使用chkconfig进行管理 
上面的方法完成了用脚本管理nginx服务的功能，比如要设置nginx开机启动等。这时可以使用chkconfig来设置。 
先将nginx服务加入chkconfig管理列表：

chkconfig --add /etc/init.d/nginx

加完这个之后，就可以使用service对nginx进行启动，重启等操作了。

service nginx start
service nginx stop
设置终端模式开机启动：

chkconfig nginx on
