CentOS6.3添加nginx系统服务的实例详解

CentOS6.3添加nginx系统服务的实例详解

前言：

今天虚拟机上配了下服务器整理了个这个 nginx 服务

要注意 – 短横杠这个符号看看复制进去后有没有乱码，我之前就遇到这个问题，郁闷了好久才发现

提示：顶部的注释不要去除否则无法注册为系统服务，

关于：chkconfig: 2345 65 37

网上搜索总结了下意思是：

2345 为启动该服务的系统环境
65 为加载的优先级别
37 为关闭的优先级别

65，37 这两个位置的数值不能相同，也不能和其它服务的数值冲突，这个我也没遇到过此类问题，如果有发现问题请对应自己的配置修改下好了

新建文件：

# vi /etc/init.d/nginx

输入内容：

#!/bin/sh 
# Comments to support chkconfig on RedHat Linux 
# chkconfig: 2345 65 37 
# description: A nginx daemon. 
                         
set -e 
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin 
DESC="nginx daemon" 
NAME=nginx 
DAEMON=/usr/local/nginx/sbin/$NAME 
SCRIPTNAME=/etc/init.d/$NAME 
                         
# If the daemon file is not found, terminate the script. 
test -x $DAEMON || exit 0 
                         
d_test() { 
  $DAEMON -t 
} 
d_start() { 
  $DAEMON || echo -n " already running" 
} 
d_stop() { 
  $DAEMON -s quit || echo -n " not running" 
} 
d_reload() { 
  $DAEMON -s reload || echo -n " could not reload" 
} 
                         
case "$1" in 
  test) 
   d_test 
   echo "." 
   ;; 
  start) 
   echo -n "Starting $DESC: $NAME" 
   d_start 
   echo "." 
   ;; 
  stop) 
   echo -n "Stopping $DESC: $NAME" 
   d_stop 
   echo "." 
   ;; 
  reload) 
   echo -n "Reloading $DESC configuration..." 
   d_reload 
   echo "reloaded." 
   ;; 
  restart) 
   echo -n "Restarting $DESC: $NAME" 
   d_stop 
   # Sleep for two seconds before starting again, this should give the 
   # Nginx daemon some time to perform a graceful stop. 
   sleep 2 
   d_start 
   echo "." 
   ;; 
  *) 
   echo "Usage: $SCRIPTNAME {test|start|stop|restart|reload}" >&2 
   exit 3 
   ;; 
esac 
                         
exit $?

chmod +x /etc/init.d/nginx 
chkconfig --add nginx 
chkconfig --level 2345 nginx on 
chkconfig --list nginx
