在运行中会出现很多错误，如需详细的执行过程需要在命令中加上-vvvv，会有蓝色字体表示执行过程

Q1：pip安装ansible附加包时编译错误

A1：未安装Python dev库
$ sudo apt-get install python-dev $ sudo apt-get install libffi-dev
Q2：源码编译或无法运行，提示没有hosts文件
$ ansible all -m ping [WARNING]: Host file not found: /etc/ansible/hosts [WARNING]: provided hosts list is empty, only localhost is available
A2：在源码的example目录中可以找到hosts文件
#mkdir /etc/ansible #cp -r /home/ansible/ansible/example/* /etc/ansible
Q3：Failed to connect to the host via ssh错误
$ansible all -m ping -u root
192.168.3.2 | UNREACHABLE! => {
"changed": false,
"msg": "Failed to connect to the host via ssh.",
"unreachable": true
}
A3：两种方法
在/etc/ansible/hosts配置将注释驱动
[ssh_connection] scp_if_ssh = True
或者命令中带有--ssh-extra-args="-o ControlPath=none" --sftp-extra-args="-o ControlPath=none
Q4：场景为已经配置好的机器，公钥已经发送，但是无法联通,也没有报错
$ ansible share -m ping -u root
192.168.30.200 | UNREACHABLE! => {
"changed": false,
"msg": "SSH Error: data could not be sent to the remote host. Make sure this host can be reached over ssh",
"unreachable": true
}
A4：更改ansible配置，开启远程被控机sftp权限
原因：在/etc/ansible/ansible.cfg中开启下列选项
[ssh_connection] scp_if_ssh = True
配置后需要检查远程被控机器的ssh是否打开sftp功能，否则无法联通
vi /etc/ssh/sshd_config Subsystem sftp /usr/lib/openssh/sftp-server
Q5：安装过程中pycrypto编译错误
会产生报错
Installed /usr/lib/python2.6/site-packages/ansible-2.2.0-py2.6.egg Processing dependencies for ansible==2.2.0 Searching for pycrypto>=2.6 Reading http://pypi.python.org/simple/pycrypto/ Best match: pycrypto 2.6.1 ...... RuntimeError: autoconf error
A5：
尝试easy_install pycrypto-2.6.1.tar.gz sudo yum install gcc
