ubuntu twemproxy 服务编写

1. 编写服务脚本

#! /bin/sh
### BEGIN INIT INFO
# Provides:          twemproxyredis
# Required-Start:    $all
# Required-Stop:
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: start twemproxyredis
### END INIT INFO
prog="nutcracker"
count=`ps -ef|grep ${prog} | grep -v grep|wc -l`;
pids=`ps -ef | grep ${prog} | grep -v grep | awk ‘{print $2}‘`
start() {
   while :
do
local_host="`hostname --fqdn`"
local_ip=`host $local_host 2>/dev/null | awk ‘{print $NF}‘`
index=`expr index "$local_ip" NX`
length=`expr ${index} - 4`
newip=${local_ip:0:${length}}
 if [ "${newip}" == "192.168.13.128" ]
    then
     break;
     else
     sleep 1s
   fi
done

   if [ $count -eq 0 ]; then
   echo "${prog} start"
   cd /usr/local/twemproxy/sbin
   nutcracker -d -c /usr/local/twemproxy/sbin/conf/nutcracker.yml -p /usr/local/twemproxy/run/nutcracker.pid -o /usr/local/twemproxy/run/nutcracker.log
   fi

}

stop() {
    if [ $count != 0 ]; then
    echo "${prog} stop"
    for skill in $pids; do
        kill -9 ${skill}
    done
    fi
}

case "$1" in
    start)
        start
        exit 0
    ;;
    stop)
        stop
        exit 0
    ;;
    reload|restart|force-reload)
        stop
        start
        exit 0
    ;;
    **)
        echo "Usage: $0 {start|stop|reload}" 1>&2
        exit 1
    ;;
esac

2 我上面编写脚本未 bin/bash 脚本，而默认ubuntu 执行的是bin/dash 下的。这里需要执行命令进行切换到/bin/bash

sudo dpkg-reconfigure dash

3 把服务添加到开机启动中

sudo update-rc.d twemproxy defaults 90 10

4 移除开机启动命令

sudo update-rc.d -f twemproxy remove

5 开启服务，并设置开机启动

service twemprxoy start
systemctl enable twemproxy
