ansible学习一（安装）

Ansible是一种集成系统的配置管理工具，使用Ansible可以批量管理服务器，应用的部署，批量的执行命令，并且Ansible还是一款轻量的开源软件，Ansible部署简单，使用yum包就可安装，但是功能的确相当的丰富，所以今天特地来聊聊Ansible。Ansible还有一个特点就是无需安装agent，使用ssh认证就可以远程控制服务器，这也是我喜欢他的一个原因，如果你python够牛的话，还可以自己定制模块，并且还有api接口，许多自动化运维平台都是调用他的。首先，先看一下安装过程：

系统：centos6.5

Python版本：python -V      

Python 2.6.6

Yum安装

rpm -Uvh http://mirrors.zju.edu.cn/epel/6/x86_64/epel-release-6-8.noarch.rpm

Yum -y install ansible

 

pip安装

//安装依赖环境

yum -y install gcc gcc-c++ git python-devel python-setuptools python-simplejson

#下载sshpass的yum源

cd /etc/yum.repos.d/

wget http://download.opensuse.org/repositories/home:Strahlex/CentOS_CentOS-6/home:Strahlex.repo

#刷新yum源数据库

yum makecache

#安装sshpass

yum -y install sshpass

#安装pip

tar zxf pip-1.5.4.tar.gz

cd pip-1.5.4

python setup.py install

#使用pip安装ansible的模块

pip install markupsafe paramiko PyYAML jinja2 httplib2 pycrypto-on-pypi

#使用pip安装ansible

pip install ansible

#查看ansible版本 如果出现版本号，则安装成功

ansible --version

安装后配置

#创建/etc/ansible

mkdir /etc/ansible

#创建主配置文件

vim /etc/ansible/ansible.cfg

##内容可从文章后面复制##

#创建/hosts文件

vim /etc/ansible/hosts

 

#进行ping测试

ansible -i hosts all -m ping

 

错误：

 

原因：服务端没有客户端ssh秘钥

解决思路：将客户端秘钥导入到服务端

解决方法：

1、在服务端运行ssh命令到相关客户端，并保存秘钥

2、在ansible主配置文件中打开选项host_key_checking = False
