ansible 自动化(1)

安装篇:

yum安装

1、安装第三方epel源
centos 6的epel
rpm -ivh http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm
查看系统版本
cat /etc/issue
2、安装ansible
yum install ansible
如果需要自定义module或者想阅读源码、使用最新版本，可以去github里下载源码
git clone https://github.com/ansible/ansible.git
3. 查看ansible在哪里
whereis ansible
ansible: /usr/bin/ansible /etc/ansible /usr/share/ansible /usr/share/man/man1/ansible.1.gz

编译安装:

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

(9)sshpass安装

#wget http://down1.chinaunix.net/distfiles/sshpass-1.05.tar.gz
#tar xf sshpass-1.05.tar.gz 
#cd sshpass-1.05
#./configure
#make && make install

我这里是编译安装需要做以下操作:(如果是编译安装ansibe则需要创建ansible文件夹)

[root@ZABBIX ~]# cd ansible-1.7.2/examples/
[root@ZABBIX examples]# ls
ansible.cfg  DOCUMENTATION.yml  hosts  issues  playbooks  scripts
[root@ZABBIX examples]# cp -r * /etc/ansible/

定义hosts文件:

[root@ZABBIX ansible]# ls
ansible.cfg  DOCUMENTATION.yml  hosts  issues  playbooks  scripts
[root@ZABBIX ansible]# vim hosts 

添加一个test组:

测试:

生成公钥,使客户端免密登录,通过ansible copy模块copy直客户端,可以批量执行命令.

[root@ZABBIX ansible]# ssh-keygen   生成密钥
[root@ZABBIX ansible]# ansible all -m copy -a 'src=~/.ssh/id_rsa.pub dest=~' –k     //copy公钥->客户端,需要输入密码,默认使用root登录,
[root@ZABBIX ansible]# ansible all -m shell -a 'cat ~/id_rsa.pub >>  ~/.ssh/authorized_keys' –k      //重定向公钥至客户端本地.ssh下.
[root@ZABBIX ansible]# ansible all -m shell -a 'cat .ssh/authorized_keys'     //验证是否成功.
[root@ZABBIX ansible]#ansible-doc –l      //查看ansible模块
[root@ZABBIX ansible]# ansible-doc command      //查看模块参数
