ansible-playbook-1:supervisor 离线安装

supervisor可以默认使用Python2, 案例使用了离线安装
虽然测试了,但是实际上安装pip 和 supervisor 中有意外产生,离线安装pip 时最好使用yum安装,rpm 有时会失败
目录结构:

[root@mini-install supervisor]# tree

注意: 添加了ignore_errors: yes
如果不添加,重复执行部分task会报错,下面的task 则中断无法继续下去

语法检测及执行

ansible-playbook -C  supervisor.yml 
ansible-playbook -i hosts supervisor.yml 
#默认使用系统指定的配置文件  可以使用自定义使用hosts
