中控机和远端主机配置完密钥后,在中控台上通过ansible检测联通性
ansible -i inventory.cfg all -m ping 10.1.1.1 | UNREACHABLE! => { "changed": false, "msg": "Failed to connect to the host via ssh: no such identity: /root/.ssh/id_rsa.bak: No such file or directory Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password). ", "unreachable": true }
通过调试选项查看
ansible -vvv -i inventory.cfg all -m ping ansible 2.6.2 config file = /home/bichenchen001/mongodb_auto_deploy/ansible.cfg configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules'] ansible python module location = /usr/lib/python2.7/site-packages/ansible executable location = /bin/ansible python version = 2.7.5 (default, Apr 11 2018, 07:36:10) [GCC 4.8.5 20150623 (Red Hat 4.8.5-28)] Using /home/bichenchen001/mongodb_auto_deploy/ansible.cfg as config file Parsed /home/bichenchen001/mongodb_auto_deploy/inventory.cfg inventory source with ini plugin META: ran handlers <10.1.1.1> ESTABLISH SSH CONNECTION FOR USER: None <10.1.1.1> SSH: EXEC ssh -C -o ControlMaster=auto -o ControlPersist=60s -o 'IdentityFile="/root/.ssh/id_rsa.bak"' -o KbdInteractiveAuthentication=no -o PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey -o PasswordAuthentication=no -o ConnectTimeout=10 -o
发现会指定 /root/.ssh/id_rsa.bak 手动创建文件解决问题
cp /root/.ssh/id_rsa /root/.ssh/id_rsa.bak
