linux - 想通过 ansible 运行简单的 root 命令

Question

我可以在远程 linux 上运行正常的 uptime 命令。但是需要 root 特权的命令出现错误。这里出了什么问题？通常，我必须登录远程 linux 和“sudo su -”，然后发出 dmidecode 命令。

[root@automation ansible]# ansible test -m shell -a "dmidecode" -c paramiko -k -b
test101.com | FAILED | rc=127 >>
/bin/sh: dmidecode: command not foundnon-zero return code




[root@automation ansible]# ansible test -m shell -a "uptime" -c paramiko -k

[root@automation ansible]# cat ansible.cfg
[defaults]
inventory       = /etc/ansible/hosts
host_key_checking = false
remote_tmp     = $HOME/.ansible/tmp

Answer 1

Q: " I am a normal user@test and have to "sudo su -" to be a root on remote "test" to do dmidecode "

问题是 root@test “找不到 dmidecode 命令”。

/bin/sh: dmidecode: command not foundnon-zero return code

答:看看PATH 是什么，dmidecode 在哪里

[root@automation ansible]# ansible test -m command -a "echo $PATH" -c paramiko -k -b
[root@automation ansible]# ansible test -m command -a "which dmidecode" -c paramiko -k -b

您可能想登录到 root@test 并找出问题所在。
