Ansible 同步模块错误 - 不存在 tty 且未指定 askpass 程序

Question

ubuntu 14.04.3 LTS ansible版本:2.1.0，远程服务器上的sshport为44022

我正在使用临时方式以 sudo 用户身份运行同步模块[nopasswd 未启用] 以同步本地和远程目录(推送)

下面是主机文件/etc/ansible/hosts

[webdb]
10.153.99.132
10.153.99.52
[webdb:vars]
ansible_ssh_user=ctuser
ansible_ssh_private_key_file=/root/.ssh/id_rsa
ansible_port=44022

下面是使用的命令:

ansible webdb -s -K  -m synchronize -a "src=/tmp/muhan 
dest=/store" -u ctuser

和(使用的目标端口)

ansible webdb -s -K  -m synchronize -a "dest_port=44022 
src=/tmp/muhan dest=/store" -u ctuser 

两个命令都输出以下错误:-

10.153.99.52 | FAILED! => {
    "changed": false, 
    "cmd": "/usr/bin/rsync --delay-updates -F --compress --archive --rsh 'ssh -i /root/.ssh/id_rsa -S none -o StrictHostKeyChecking=no -o Port=44022' --rsync-path=\"sudo rsync\" --out-format='<<CHANGED>>%i %n%L' \"/tmp/muhan\" \"ctuser@10.153.99.52:/store\"",

Answer 1

您可以从多个角度解决这个问题:

• 禁用 sudo tty 要求:sed -i 's/Defaults requiretty/Defaults !requiretty/g'/etc/sudoers(这在您使用 Ansible 的所有节点上)

• 更改 ansible.cfg 以具有 ssh 的 tty 标志 http://docs.ansible.com/ansible/intro_configuration.html#ssh-args (这仅在您执行 Ansible 的节点上)

您需要的确切开关:

ssh_args = -tt
