Ansible安装过程中常遇到的错误（FAQ）

1.安装完成后允许命令报错

Traceback (most recent call last):

  File "/usr/bin/ansible", line , in <module>

    (runner, results) = cli.run(options, args)

  File "/usr/bin/ansible", line , in run

    extra_vars=extra_vars,

  File "/usr/lib/python2.6/site-packages/ansible/runner/__init__.py", line , in __init__

    cmd = subprocess.Popen(['ssh','-o','ControlPersist'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)

  File "/usr/lib64/python2.6/subprocess.py", line , in __init__

    errread, errwrite)

  File "/usr/lib64/python2.6/subprocess.py", line , in _execute_child

    raise child_exception

OSError: [Errno ] No such file or directory

解决方法：

# yum 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

}

解决方法：

python版本过低，要不升级python要不就升级安装python-simplejson。

3.安装完成后连接客户端服务器报错

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.

解决方法：

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)?

解决方法：

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

解决方法：

需要你在最后添加参数-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

解决方法：

# yum install libselinux-python -y
