通过python启动java程序。未验证

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
