centos6.5-7编译安装Ansible详细部署
一、基础介绍
==========================================================================================
ansible是新出现的自动化运维工具，基于Python开发，集合了众多运维工具（puppet、cfengine、chef、func、fabric）的优点，实现了批量系统配置、批量程序部署、批量运行命令等功能。
ansible是基于模块工作的，本身没有批量部署的能力。真正具有批量部署的是ansible所运行的模块，ansible只是提供一种框架。主要包括：
(1)、连接插件connection plugins：负责和被监控端实现通信
(2)、host inventory：指定操作的主机，是一个配置文件里面定义监控的主机
(3)、各种模块核心模块、command模块、自定义模块
(4)、借助于插件完成记录日志邮件等功能；
(5)、playbook：剧本执行多个任务时，非必需可以让节点一次性运行多个任务
1、Ansible基础安装
(1)、python2.7安装 #目前还不支持3X的版本，你也可以用
https://www.python.org/ftp/python/2.7.8/Python-2.7.8.tgz tar xvzf Python-2.7.8.tgz cd Python-2.7.8 ./configure --prefix=/usr/local make && make install
将python头文件拷贝到标准目录，以避免编译ansible时，找不到所需的头文件
cd /usr/local/include/python2.7 cp -a ./* /usr/local/include/
备份旧版本的python，并符号链接新版本的python
cd /usr/bin mv python python.old ln -s /usr/local/bin/python .
修改yum脚本，使其指向旧版本的python，已避免其无法运行
centos6修改如下
vim /usr/bin/yum 修改为 #!/usr/bin/python.old
centos7 增加修改vim /usr/libexec/urlgrabber-ext-down 修改为 #!/usr/bin/python.old

2、Ansible配置
(1)、SSH免密钥登录设置
分别在各个机器上执行SSH无密码验证登录的实现
vim /etc/ssh/sshd_config 开启 RSAAuthentication yes # 启用 RSA 认证 PubkeyAuthentication yes # 启用公钥私钥配对认证方式 AuthorizedKeysFile .ssh/authorized_keys # 公钥文件路径 ssh-keygen -t rsa 生成密钥文件 cd ~/.ssh/ cat id_rsa.pub >> authorized_keys chmod 600 authorized_keys ssh-copy-id -i ~/.ssh/id_rsa.pub IP 重启SSH服务： /bin/systemctl restart sshd.service /etc/init.d/sshd restart
将所有机器的key都在加在各自的authorized_keys里。
重启SSH服务：
/bin/systemctl restart sshd.service
(2)、ansible配置
mkdir -p /etc/ansible vim /etc/ansible/ansible.cfg inventory = /etc/ansible/hosts remote_port = 22
主机组定义
vim /etc/ansible/hosts [web59] 192.168.1.59
(3)、简单测试
ansible all -m command -a 'uptime'
192.168.1.229 | SUCCESS | rc=0 >>
13:00:08 up 5 days, 18:58, 2 users, load average: 0.01, 0.03, 0.00
192.168.1.59 | SUCCESS | rc=0 >>
13:03:29 up 5 days, 19:20, 5 users, load average: 0.00, 0.00, 0.00
