Ansible专题二：自动化运维工具Ansible部署

我们先来看一下公司内部的效果，18服务器是ansible服务所在的机器，他同时监控了4台机器，通过发送指令可以获取其他机器的硬盘信息；


1、Ansible基础安装
(1)、python2.7安装
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 --jobs=`grep processor/proc/cpuinfo | wc -l`
# 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 python2.6
# 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
# vim /usr/bin/yum
#!/usr/bin/python  -->  #!/usr/bin/python2.6

(2)、setuptools模块安装
https://pypi.python.org/packages/source/s/setuptools/setuptools-7.0.tar.gz
# tar xvzf setuptools-7.0.tar.gz
# cd setuptools-7.0
# python setup.py install

(3)、pycrypto模块安装
https://pypi.python.org/packages/source/p/pycrypto/pycrypto-2.6.1.tar.gz
# tar xvzf pycrypto-2.6.1.tar.gz
# cd pycrypto-2.6.1
# python setup.py install

(4)、PyYAML模块安装
http://pyyaml.org/download/libyaml/yaml-0.1.5.tar.gz
# tar xvzf yaml-0.1.5.tar.gz
# cd yaml-0.1.5
# ./configure --prefix=/usr/local
# make --jobs=`grep processor/proc/cpuinfo | wc -l`
# make install

https://pypi.python.org/packages/source/P/PyYAML/PyYAML-3.11.tar.gz
# tar xvzf PyYAML-3.11.tar.gz
# cd PyYAML-3.11
# python setup.py install

(5)、Jinja2模块安装
https://pypi.python.org/packages/source/M/MarkupSafe/MarkupSafe-0.9.3.tar.gz
# tar xvzf MarkupSafe-0.9.3.tar.gz
# cd MarkupSafe-0.9.3
# python setup.py install

https://pypi.python.org/packages/source/J/Jinja2/Jinja2-2.7.3.tar.gz
# tar xvzf Jinja2-2.7.3.tar.gz 
# cd Jinja2-2.7.3
# python setup.py install

(6)、paramiko模块安装
https://pypi.python.org/packages/source/e/ecdsa/ecdsa-0.11.tar.gz
# tar xvzf ecdsa-0.11.tar.gz
# cd ecdsa-0.11
# python setup.py install

https://pypi.python.org/packages/source/p/paramiko/paramiko-1.15.1.tar.gz
# tar xvzf paramiko-1.15.1.tar.gz
# cd paramiko-1.15.1
# python setup.py install

(7)、simplejson模块安装
https://pypi.python.org/packages/source/s/simplejson/simplejson-3.6.5.tar.gz
# tar xvzf simplejson-3.6.5.tar.gz
# cd simplejson-3.6.5
# python setup.py install

(8)、ansible安装
https://github.com/ansible/ansible/archive/v1.7.2.tar.gz
# tar xvzf ansible-1.7.2.tar.gz
# cd ansible-1.7.2
# python setup.py install

2、Ansible配置
(1)、SSH免密钥登录设置
## 生成公钥/私钥
# ssh-keygen -t rsa -P ''

## 写入信任文件（将/root/.ssh/id_rsa_storm1.pub分发到其他服务器，并在所有服务器上执行如下指令）：
# cat /root/.ssh/id_rsa_storm1.pub >> /root/.ssh/authorized_keys
# chmod 600 /root/.ssh/authorized_keys

(2)、ansible配置
# mkdir -p /etc/ansible
# vim /etc/ansible/ansible.cfg
