通过python启动java程序，挺方便的分享下。

最近部署了java程序，刚开始用shell来启动，启动过程不友好也不方便，也没有守护进程。今年在整理资料的时候，发现了珍藏一套启动脚本。

挺方便的。记录下。以免忘记

这是我的java程序结构

一个jar文件，一个config配置文件 一个lib依赖包。

重点贴出 appStoreServer.py脚本代码

#!/usr/bin/python
import os, sys, time, commands

_program = \'appStoreServer.jar\'
_daemon = \'appStoreServer.py\'

def getProgramPid():
    result = commands.getoutput("ps aux | grep java \
        | grep %s | grep -v grep | awk \'{print $2}\'" % _program)
    return result

def getDaemonPid():
    result = commands.getoutput("ps aux | grep python \
        | grep \'%s monitor\' | grep -v grep | awk \'{print $2}\'" % _daemon)
    return result

def startProgram():
    p_pid = getProgramPid()
    if p_pid != \'\':
        print(\'It seems this program is already running...\')
    else:
        print(\'Starting program...\')
        if os.system(\'nohup java -Dfile.encoding=UTF-8 -server -Xms1024m -Xmx1024m -Xmn256m \
		-cp %s:config/:lib/* com.xxxx.Bootstrap >> log/stdio.log 2>&1 &\' % _program) == 0:
            print(\'start program successfully and pid is \' + getProgramPid())

def startDaemon():
    d_pid = getDaemonPid()
    if d_pid != \'\':
        print(\'It seems this daemon is already running...\')
    else:
        print(\'Starting daemon...\')
        if os.system(\'nohup python %s monitor >> log/daemon.log 2>&1 &\' % _daemon) == 0:
            print(\'start daemon successfully and pid is \' + getDaemonPid())

def stopProgram():
    p_pid = getProgramPid()
    if p_pid == \'\':
        print(\'It seems this program is not running...\')
    else:
        os.system(\'kill \' + p_pid)
        print(\'program stopped\')

def stopDaemon():
    d_pid = getDaemonPid()
    if d_pid == \'\':
        print(\'It seems daemon is not running...\')
    else:
        os.system(\'kill \' + d_pid)
        print(\'daemon stopped\')

def monitor():
    while 1:
        time.sleep(10)
        p_pid = getProgramPid()
        if p_pid == \'\':
            print(\'It seems this program is not running. Start it now!\')
            startProgram()

if __name__ == \'__main__\':
    if(len(sys.argv) == 2):
        args = sys.argv[1]
    else:
        args = raw_input(\'Enter args: \')
    
    logPath = os.path.curdir + os.sep + \'log\'
    if not os.path.exists(logPath):
        os.mkdir(logPath)

    if args == \'start\':
        startProgram()       
        startDaemon()
    elif args == \'stop\':
        stopDaemon()
        stopProgram()
    elif args == \'restart\':
        stopDaemon()
        stopProgram()
        time.sleep(3)
        startProgram()       
        startDaemon()
    elif args == \'monitor\':
        monitor()
    else:
        print(\'nothing to do\')  

　　只需要修改你的jar 和main class 入口(这就是文中 com.xxx.bootstrap部分)。python调用了nuhop命令，退出终端也可以后台运行，挺方便的，重点的是还有daemo进程

 

修改了，开始启动 java程序
