Question

我有一个主人和一个奴隶。
我可以通过ssh从master连接到slave。
Ansible 无法从主服务器连接。

问题：我做错了什么，所以ansible无法连接，但是ssh可以吗？

通过ssh从主服务器到服务器的成功连接

vagrant@master:~$ ssh slave.local
Enter passphrase for key '/home/vagrant/.ssh/id_rsa':
vagrant@slave.local's password:

Ansible错误：＆＃34; 权限被拒绝（公钥，密码）＆＃34;

vagrant@master:~$ ansible all -m ping -u vagrant
The authenticity of host 'slave.local (10.0.0.11)' can't be established.
ECDSA key fingerprint is SHA256:tRGlinvTj/c2gpTayZ/mYzyWbs63s+BUX81TdKJ+0jQ.
Are you sure you want to continue connecting (yes/no)? yes
Enter passphrase for key '/home/vagrant/.ssh/id_rsa':

slave.local | UNREACHABLE! => {
"changed": false,
"msg": "Failed to connect to the host via ssh: Warning: Permanently added 'slave.local' (ECDSA) to the list of known hosts.\r\nPermission denied (publickey,password).\r\n",
"unreachable": true
}

这是我的主持人文件

vagrant@master:~$ cat /etc/ansible/hosts
[web]
slave.local

Answer 1

解决方案是将openSSH格式的私钥添加到文件 /home/vagrant/.ssh/id_rsa
这是ansible正在寻找钥匙的地方。

我可以通过在详细模式下启动ansible，使用键“-vvvv”

来查找

ansible all -m ping -u vagrant -vvvv

详细输出

10.0.0.11 | UNREACHABLE! => {
    "changed": false,
    "msg": "Failed to connect to the host via ssh: OpenSSH_7.2p2 Ubuntu-4ubuntu2.2, OpenSSL 1.0.2g  1 Mar 2016\r\ndebug1: Reading configuration data /etc/ssh/ssh_config\r\ndebug1: /etc/ssh/ssh_config line 19: Applying options for *\r\ndebug1: auto-mux: Trying existing master\r\ndebug1: Control socket \"/home/vagrant/.ansible/cp/a72f4dc97e\" does not exist\r\ndebug2: resolving \"10.0.0.11\" port 22\r\ndebug2: ssh_connect_direct: needpriv 0\r\ndebug1: Connecting to 10.0.0.11 [10.0.0.11] port 22.\r\ndebug2: fd 3 setting O_NONBLOCK\r\ndebug1: fd 3 clearing O_NONBLOCK\r\ndebug1: Connection established.\r\ndebug3: timeout: 10000 ms remain after connect\r\ndebug1: key_load_public: No such file or directory\r\ndebug1: identity file /home/vagrant/.ssh/id_rsa type -1\r\ndebug1: key_load_public: No such file or directory\r\ndebug1: identity file ...

Ansible说＆＃34;权限被拒绝（公钥，密码）＆＃34;
