Question

当我尝试连接到CentOS服务器时，我收到以下错误

boby@hon-pc-01:~/www/ansible $ ansible centos -vvv -i hosts -a "uname -a"
Using /home/boby/www/ansible/ansible.cfg as config file

}

我可以将Debian服务器连接到任何问题

boby@hon-pc-01:~/www/ansible $ ansible ubuntu -vvv -i hosts -a "uname -a"

boby@hon-pc-01:~/www/ansible $

这是我的主机文件

boby@hon-pc-01:~/www/ansible $ cat hosts
[ubuntu]
vm705n:3333

[centos]
root@209.236.74.192:3333
boby@hon-pc-01:~/www/ansible $

知道为什么它不能用于CentOS 6服务器吗？

修改

我修好了。问题是hosts @在hosts文件中。由于某种原因，SSH命令没有接受端口3333，因为root @ present存在于主机文件中。

Answer 1

问题出在主机文件中。

boby@hon-pc-01:~/www/ansible $ cat hosts
[ubuntu]
vm705n:3333

[centos]
root@209.236.74.192:3333
boby@hon-pc-01:~/www/ansible $

用209.236.74.192:3333替换了root@209.236.74.192：3333并开始工作。

ansible无法连接到centos
