Ansible common errors encountered during installation

1. Allow command error after installation is complete

traceback  (most recent call last):  file  "/usr/bin/ansible",  line  197, in <module>     (runner, results)  = cli.run ( Options, args)   File  "/usr/bin/ansible", line 163, in run     extra_vars=extra_vars,  File  "/usr/lib/python2.6/site-packages/ansible/runner/__ Init__.py ",  line 233, in __init__    cmd = subprocess. Popen ([' ssh ', '-o ', ' controlpersist '], stdout=subprocess. Pipe, stderr=subprocess. PIPE)   File  "/usr/lib64/python2.6/subprocess.py",  line 639, in __init__     errread, errwrite)   File  "/usr/lib64/python2.6/subprocess.py",  line 1228, in _execute_child    raise child_exceptionoserror:  [Errno 2] No such file or Directory 

Workaround:

# yum Install openssh-clients

2. Error:ansible requires a JSON module appears, none found!

SSH password:10.0.1.110 | FAILED >> {"FAILED": True, "MSG": "Error:ansible requires a JSON module, nonefound!", "parsed": false}

Workaround:

Python version is too low, either upgrade Python or upgrade the installation Python-simplejson.

3. Connect client server after installation complete error

failed => using a ssh password insteadof a key is not  possible because Host Key checking is enabled and sshpass  Doesnot support this.  please add this host ' Sfingerprint to your  known_hosts file to manage this host. 

Workaround:

On the ansible server, use SSH to log in to the server configured in/etc/ansible/hosts. Then use ansible again to manage will not report the above error! But it would be troublesome to land in such large quantities. Because the default ansible is verified using key, if the server using the password login, use ansible, or modify the ansible.cfg configuration file Ask_pass = True to uncomment, or run the command when you add-K, which means-K,-- Ask-pass ask for SSH password. Re-modify: host_key_checking= false can

4. If the client is not in Know_hosts, the error will be

Paramiko:the authenticity of host ' 192.168.24.15 ' can ' t be established. The Ssh-rsa key fingerprint is397c139fd4b0d763fcffaee346a4bf6b. Is you sure want to continueconnecting (yes/no)?

Workaround:

Need to modify Ansible.cfg's #host_key_checking= false uncomment

5. Appears FAILED = Failed:not a valid DSA private key file
workaround:

You need to add the parameter-K at the end

6.OPENSSH cannot log in error after upgrade

PAM unable Todlopen (/lib64/security/pam_stack.so):/lib64/security/pam_stack.so:cannot openshared Objectfile:no such File or directory

Workaround:

The/etc/pam.d/sshd file will be modified after the SSHRPM upgrade. You need to back up this file before upgrading to log in after the last restore.

7. First time system initialization runtime ansible user key times wrong

Failed: [127.0.0.1] =>{"checksum": "f5f2f20fc0774be961fffb951a50023e31abe920", "Failed": True}msg:aborting, Target uses selinux but pythonbindings (libselinux-python) aren ' t installed! Fatal:all hosts have already failed–aborting

Workaround:

# yum Install Libselinux-python-y
