# 显式加载环境变量
os.system('source /etc/profile')
# 我这里的jdk没有使用apt安装，所以需要手动添加环境变量，确定能通过os.system启动可以删掉这几个
os.environ['PATH'] = '/home/ubuntu/jdk1.8.0_192/bin:' + os.environ['PATH']

# 检查Java版本
os.system('java -version')

# 启动kiftd
os.system('java -jar kiftd-*-RELEASE.jar -start')

这里使用kiftd文件系统进行测试，可以穿过学校vlab虚拟机的防火墙从公网访问
