【记录】服务启动脚本管理

通常使用.sh文件来启动服务，记录两个常用的：启动进程和杀死进程；

restart.sh

#!/bin/sh
old_pid=$(ps ax|grep service.py|grep -v grep|awk '{print $1}')
echo "old_pid=${old_pid}"

if [ -z ${old_pid} ];then
    echo "Process Non-existent !"
    echo "Starting Process...."
    nohup python service.py >log.log 2>&1 &
else
    kill -9 ${old_pid}
    mid_pid=$(ps ax|grep service.py|grep -v grep|awk '{print $1}')
    if [ -z ${mid_pid} ];then
        echo "Process Close Success !"
        sleep 1
        echo "Start Restarting....."
        nohup python service.py >log.log 2>&1 &
    else
        echo "Process Close Fail !"
        exit 1
    fi
fi
echo "Please wait 8 s ..."
sleep 8
new_pid=$(ps ax|grep service.py|grep -v grep|awk '{print $1}')
if [ -z ${new_pid} ];then
    echo "Restart Fail !"
else
    echo "Restart Success !"
    echo "new_pid=${new_pid}"
fi

kill.sh

#!/bin/sh
old_pid=$(ps ax|grep service.py|grep -v grep|awk '{print $1}')
echo "find process..."
echo "old_pid=${old_pid}"
if [ -z ${old_pid} ];then
    echo "Process Non-existent !"
else
    kill -9 ${old_pid}
    mid_pid=$(ps ax|grep service.py|grep -v grep|awk '{print $1}')
    if [ -z ${mid_pid} ];then
        echo "Process Close Success !"
        sleep 1
    else
        echo "Process Close Fail !"
        exit 1
    fi
fi
