使用visudo命令进行sudo配置文件的编写

## The COMMANDS section may have other options added to it.
##
## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL
ansible ALL=(ALL)       ALL
## Allows members of the 'sys' group to run networking, software,
## service management apps and more.

当前需要做sudo的用户为ansible，即将其添入root行下方 
保存退出即可

免密码sudo

## The COMMANDS section may have other options added to it.
##
## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL
ansible ALL=(ALL)       NOPASSWD:ALL
## Allows members of the 'sys' group to run networking, software,
## service management apps and more.

只需要将对应用户的行设置 NOPASSWD即可实现无密码sudo
