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。(百度百科),2015年RedHat收购ansible。
主机环境:
OS:Red Hat Enterprise Linux Server release 6.6 (Santiago) x86_64
IP:172.16.10.180
Python 2.6.6
注:操作系统最小化安装
节点:
OS:Oracle Linux Server release 5.8
IP:172.16.10.10、172.16.10.200
Python 2.4.3
1、安装开发工具:
# yum -y groupinstall “Development tools”
2、安装six、yaml
# rpm -ivh python-six-1.9.0-1.el6.pp.noarch.rpm
# rpm -ivh python-yaml-3.09-3.el6.rf.x86_64.rpm
3、安装ansible
# yum install ansible
注:受控节点需要安装python-simplejson
4、生成秘钥文件
# ./sshUserSetup.sh -user root -hosts “172.16.10.10 172.16.10.200”
输入yes和两台主机的root密码即可完成172.16.10.180->172.16.10.10、172.16.10.180->172.16.10.200的验证
或者:
# ssh-keygen -t rsa -P ”
在/root/.ssh/下生成文件id_rsa.pub,拷贝到所有受控机并执行以下操作:
# cat /root/.ssh/id_rsa.pub >> /root/.ssh/authorized_keys
# chmod 600 /root/.ssh/authorized_keys
5、修改hosts文件
# cd /etc/ansible/
# cat /etc/ansible/hosts
…
[dbservers]
172.16.10.10
172.16.10.200
6、修改ansible.cfg文件
# cat /etc/ansible/ansible.cfg
…
remote_port = 36000
…
private_key_file = /root/.ssh/id_rsa
7、测试
# ansible all -m ping
# all指所有定的主机
172.16.10.10 | SUCCESS => {
“changed”: false,
“ping”: “pong”
}
172.16.10.200 | SUCCESS => {
“changed”: false,
“ping”: “pong”
}
# ansible dbservers -m ping
172.16.10.200 | SUCCESS => {
“changed”: false,
“ping”: “pong”
}
172.16.10.10 | SUCCESS => {
“changed”: false,
“ping”: “pong”
}
8、常见错误:
A、”msg”: “Error: ansible requires the stdlib json or simplejson module, neither was found!”
受控端需要安装python-simplejson
B、FAILED => module command not found in configured module paths. Additionally, core modules are missing. If this is a checkout, run ‘git submodule update –init –recursive’ to correct this problem.
安装过程有问题,重新安装
C、FAILED => to use the ‘ssh’ connection type with passwords, you must install the sshpass program
安装sshpass
