ansible简介绍
1.ansible是什么？
l ansible是一个基于Python开发的自动化运维工具 ！
l 其功能实现基于SSH远程连接服务！
l ansible可以实现批量系统配置、批量软件部署、批量文件拷贝、批量运行命令等功能
2.ansible软件特性
l 不需要单独安装客户端（no agents），基于系统自带的sshd服务，sshd就相当于ansible的客户端。
l 不需要服务端(no servers)。
l 需要依靠大量的模块实现批量管理。?
l 配置文件/etc/ansible/ansible.cfg,不用配置
3.ansible软件执行结果
l 输出内容显示绿色：表示执行成功，当没有任何改变
l 输出内容显示黄色：表示执行成功，蛋对被管理主机进行了改变
l 输出内容显示红色：表示执行失败！！！
4.ansible的官方文档
http://docs.ansible.com/
ansible的部署：
1.因为ansible基于ssh所以需要密钥对可参考http://www.cnblogs.com/ExzaiTin/p/7687410.html
2.被管理端需要安装libselinux-python
yum install libselinux-python -y
3.管理端安装ansible软件配置ansible的hosts文件（管理机和被管理机可以基于ssh免密钥，也可以在ansible的hosts文件中写入被管理机的密码）配置格式如下（仅供参考，可以不写密码和用户，[]里表示自己定义的主机组，如果域名可以解析的话ip也可以写为域名）
4.ansible命令格式
ansible <host-pattern> [-m module_name] [-a args] [options]
<host-pattern> 自己定义的主机组
[-m module_name] 指定模块
[-a args] 指定要执行的动作
ansible常用模块：
1.ping-测试模块
ansible test -m ping 172.16.1.8 | SUCCESS => { "changed": false, "ping": "pong" } ##以上为可以正常链接字体会显示为绿色 172.16.1.41 | UNREACHABLE! => { "changed": false, "msg": "Failed to connect to the host via ssh: ssh: connect to host 172.16.1.41 port 22: Connection timed out\r\n", "unreachable": true } ##以上为无法链接字体会显示为红色
2.setup-远程查看主机的配置信息
ansible test -m setup
3.command-远程执行命令
4.shell-远程节点执行模块
