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
