一、报错

1、出现Error:

ansible requires a json module, none found! SSH password: 192.168.56.80 | FAILED >> { "failed": true, "msg": "Error: ansible requires a json module, nonefound!", "parsed": false }

解决:python版本过低,要不升级python要不就安装python-simplejson 2、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: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

3、如果客户端不在know_hosts里将会报错

paramiko: The authenticity of host '192.168.56.80'can't be established. The ssh-rsa key fingerprint is397c139fd4b0d763fcffaee346a4bf6b. Are you sure you want to continueconnecting (yes/no)? 解决:需要修改ansible.cfg的#host_key_checking= False取消注释

4、出现FAILED => FAILED: not a valid DSA private key file

解决:需要你在最后添加参数-k

5、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: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。

6、pip安装完成后,运行ansible报错:

File "/usr/lib64/python2.6/subprocess.py",line 642, in init errread, errwrite) 解决:安装:yum installopenssh-clients

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:# yuminstall libselinux-python -y 注意这个是在 host机器上安装,不是在ansible控制机器上。
