autorestart=unexpected : 这是默认选项,当目标进程 “异常” 退出时,服务进程将自动重启目标进程,这里的 “异常” 指的是目标进程的 exitcode 与exitcodes 配置的参数不一致时。_exitcodes_ 配置用于指定程序 “预期” 的退出代码列表,默认为 exitcodes=0。 用以下代码来进行测试行为: 代码语言:javascript 代码运行...
1、当我们输入任何yum命令,都会报错。原因是升级python后,导致yum所需版本不一致导致! 2、如图,我将python版本编译安装python3.3.0。将3.3链接到/usr/bin/python. 3、我们查看/usr/bin/yum 文件,可以看到,yum调用的是/usr/bin/python这个文件。所以改变之后就会报错。 4、这个时候我们只需要修改yum配置文件,将pyt...

subprocess.call(), subprocess.run(), and subprocess.Popen() differ in how they execute commands and handle process output and return codes. multiprocessing is for parallel execution within Python, while subprocess manages external processes. To execute multiple commands in sequence using subprocess, yo...
