ubuntu 添加nginx系统服务详细说明

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

代码如下：

#!/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
