ansible安装配置与简单使用
前言：
AnsibleWorks成立于2012年，由自动化工具Cobbler及Func的开发者Michael DeHaan创建。其Ansible平台是一个开源的配置及计算机管理平台。可实现多节点的软件部署，执行特定任务并进行配置管理。
Ansible 跟其他IT自动化技术的区别在于其关注点并非配置管理、应用部署或IT流程工作流，而是提供一个统一的界面来协调所有的IT自动化功能，因此 Ansible的系统更加易用，部署更快。受管理的节点无需安装额外的远程控制软件，由平台通过SSH（Secure SHell）对其进行管理，因此十分方便。其模块支持JSON等标准输出格式，可采用任何编程语言重写。
Ansible可以让用户避免编写脚本或代码来管理应用，同时还能搭建工作流实现IT任务的自动化执行。IT自动化可以降低技术门槛及对传统IT的依赖，从而加快项目的交付速度。
ansible有如下优点：
1、轻量级，他不需要去客户端安装agent，更新时，只需要在操作机上进行一次更新即可
2、批量任务执行可以写成脚本，而且不用分发到远程就可以执行
3、使用python编写的，维护更简单
4、支持sudo

——安装ansible
1）创建ansible用户
[root@node1 ~]# useradd ansible [root@node1 ~]# passwd ansible 更改用户 ansible 的密码 。 新的 密码： 重新输入新的 密码： passwd： 所有的身份验证令牌已经成功更新。
2）赋予root权限
[root@node1 ~]# vi /etc/sudoers ansible ALL=(ALL) NOPASSWD:ALL
3）安装ansible
[root@node1 ~]# yum install PyYAML.x86_64 python-paramiko.noarch python-jinja2.x86_64 python-devel -y [root@node1 ~]# wget https://pypi.python.org/packages/source/a/ansible/ansible-1.7.2.tar.gz [root@node1 ~]#wget https://pypi.python.org/packages/source/s/setuptools/setuptools-7.0.tar.gz [root@node1 ~]# tar zfxv setuptools-7.0.tar.gz [root@node1 ~]# cd setuptools-7.0 [root@node1 setuptools-7.0]# python setup.py install [root@node1 setuptools-7.0]# cd .. [root@node1 ~]# tar fzvx ansible-1.7.2.tar.gz [root@node1 ~]# cd ansible-1.7.2 [root@node1 ansible-1.7.2]# python setup.py build [root@node1 ansible-1.7.2]# python setup.py install [root@node1 ansible-1.7.2]# mkdir /etc/ansible [root@node1 ansible-1.7.2]# cp examples/ansible.cfg /etc/ansible/ [root@node1 ansible-1.7.2]# cp examples/hosts /etc/ansible/
4）配置ansible
4）配置ansible
[root@node1 ansible-1.7.2]# vi /etc/ansible/ansible.cfg hostfile = /etc/ansible/hosts library = /usr/share/ansible remote_tmp = $HOME/.ansible/tmp pattern = * forks = 5 poll_interval = 15 sudo_user = ansible #ask_sudo_pass = True #ask_pass = True transport = smart remote_port = 22 module_lang = C [root@node1 ansible-1.7.2]# vi /etc/ansible/hosts #server [localhost] 127.0.0.1 #client [client] 192.168.253.129 192.168.253.130 192.168.253.131
5）ssh互信
[root@node1 ansible-1.7.2]# su - ansible [ansible@node1 ~]$ ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/home/ansible/.ssh/id_rsa): Created directory ‘/home/ansible/.ssh‘.
