通過python啟動java程式，挺方便的分享下。

最近部署了java程式，剛開始用shell來啟動，啟動過程不友好也不方便，也沒有守護進程。今年在整理資料的時候，發現了珍藏一套啟動指令碼。

挺方便的。記錄下。以免忘記

這是我的java程式結構

一個jar檔案，一個config設定檔 一個lib依賴包。

重點貼出 appStoreServer.py指令碼代碼

#!/usr/bin/pythonimport 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 resultdef getDaemonPid():    result = commands.getoutput("ps aux | grep python \        | grep '%s monitor' | grep -v grep | awk '{print $2}'" % _daemon)    return resultdef 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(這就是文中 com.xxx.bootstrap部分)。python調用了nuhop命令，退出終端也可以後台運行，挺方便的，重點的是還有daemo進程

 

修改了，開始啟動 java程式
