每天都要更新微服务, 写了个python脚本, 实现linux下一键启动jar包

每天都要更新微服务,  而且可能还要退回到上一个jar包, 就写了个python脚本, 一键启动jar包, 括杀死进程, 启动参数, 

只需设置 # sDir = 程序目录名, sName = jar包前缀, ymlName = 配置文件, out = 日志, sDtVer = 文件格式

1. 设置的参数  yml文件

2. jar文件  *-yyyymmddhhmmss.jar

参数启动写死了, 诸如一些判断还没有写进来, 需要完善

通过sheel启动就可以了 

#/bin/bash
python go2.py

go.py脚本如下, 启动最新修改的jar文件

import sys
import os
import re
import time
import subprocess

print "waht-app-jar信息"
# 把jar包, yml, log文件夹 放在工程目录
# sDir = 程序目录名, sName = jar包, ymlName = 配置文件, out = 日志
sName = 'wqht-hl-1.1-SNAPSHOT'
ymlName = ""
ymlName = "application-release.yml"
sDir = "/srv/wqht-app-hl"
outName = "log-"+time.strftime("%Y%m%d-%H%M%S", time.localtime()) +".out"

logPath = sDir + "/log"
isExists = os.path.exists(logPath)	
if not isExists: #判断结果
	os.makedirs(logPath)

sline = '................................................................................'
print('\033[1;32m' + sline+' \033[0m') 
print("查看进程:" + '\033[1;32m' + sName+' \033[0m') 

cmdProc = "ps -ef | grep " + sName + " | grep -v grep"
cmdKill = 'ps -ef | grep ' + sName + ' | grep -v grep | awk \'{print "kill "$2}\' | sh'
out1 = 'ps -ef '
#print('\033[1;95m' + "kill:" + sName + ' \033[0m') 
#print('\033[1;35mKILL: ' + sName +'\033[0m')
#先杀它3次
for i in range(1, 3):	
	#print(cmdProc) 
	out1,out2 = subprocess.Popen(cmdProc, shell=True, stdout=subprocess.PIPE).communicate()
	if out1 != '' : #
		print("\033[1;35m尝试第" + str(i) + "次杀死进程:\033[0m" + out1)	
		subprocess.Popen(cmdKill, shell=True, stdout=subprocess.PIPE)
		time.sleep(2)
	else :
		print('\033[1;32m就绪...\033[0m') 
		time.sleep(1)
		break
out1,out2 = subprocess.Popen(cmdProc, shell=True, stdout=subprocess.PIPE).communicate()
if out1 != '' : #
	print("\033[1;35m进程冥顽不灵:\033[0m" + out1 + " 枪毙5s!!!")	
	cmdKill = 'ps -ef | grep ' + sName + ' | grep -v grep | awk \'{print "kill -9 "$2}\' | sh'
	subprocess.Popen(cmdKill, shell=True, stdout=subprocess.PIPE)
	time.sleep(5)

#获取最新创建的jar文件

	if not filename.endswith('.jar'):

	cc.append(kk)

for i in sorted(cc):
	lastName = dd[i]

print('jar文件:'+'\033[1;32m' + lastName + '\033[0m') 

cmdJar = "java -jar ./" + lastName + " --spring.config.location=./" + ymlName

print('----------------------------------------------------------------------')
print(cmdJar)
