1、安装完成后允许命令出错
Traceback (most recent call last):
File "/usr/bin/ansible", line 197, in
(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_exception
OSError: [Errno 2] No such file or directory
解决办法
yum -y install openssh-clients
2.出现Error: ansible requires a json module, none found!
SSH password:
10.0.1.110 | FAILED >> {
"failed": true,
"msg": "Error: ansible requires a json module, nonefound!",
"parsed": false
}
解决办法
python版本过低，可以升级python或者python-simplejson
3、安装完成后链接客户端报错（配图为我在使用ansible推送文件到客户端的时候遇到的，这个客户端是第一次推送）
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.
解决办法：
在ansible 服务器上使用ssh 登陆下/etc/ansible/hosts 里面配置的服务器。然后再次使用ansible 去管理就不会报上面的错误了！但这样大批量登陆就麻烦来。因为默认ansible是使用key验证的，如果使用密码登陆的服务器，使用ansible的话，要不修改ansible.cfg配置文件的ask_pass = True给取消注释，要不就在运行命令时候加上-k，这个意思是-k, --ask-pass ask for SSH password。再修改：host_key_checking= False即可
4.如果客户端不在know_hosts里将会报错
paramiko: The authenticity of host '192.168.24.15'can't be established.
The ssh-rsa key fingerprint is397c139fd4b0d763fcffaee346a4bf6b.
Are you sure you want to continueconnecting (yes/no)?
解决办法
需要修改ansible.cfg的#host_key_checking= False取消注释
5.出现FAILED => FAILED: not a valid DSA private key file
解决办法：
需要你在最后命令内添加参数-k
6.openssh升级后无法登录报错
PAM unable todlopen(/lib64/security/pam_stack.so): /lib64/security/pam_stack.so: cannot openshared object
file: No such file or directory
解决方法：
sshrpm 升级后会修改/etc/pam.d/sshd 文件。需要升级前备份此文件最后还原即可登录。
7.第一次系统初始化运行生成本机ansible用户key时报错
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
解决办法
yum -y install libselinux-python
