ansible 的安装配置
Ansible中文权威指南:https://ansible-tran.readthedocs.io
环境准备：
1 ansible 192.168.1.10 管理机器
2 web1 192.168.1.11 托管机器
3 web2 192.168.1.12 托管机器
4 db1 192.168.1.21 托管机器
5 db2 192.168.1.22 托管机器
6 cache 192.168.1.33 托管机器
一、在真机上ftp配置下配置ansible的yum源供ansible虚拟机使用：
1 [root@ansible ~]# cat /etc/yum.repos.d/centos7.repo 2 [centos] 3 name=centos7 4 baseurl=ftp://192.168.1.254/centos7 5 enabled=1 6 gpgcheck=0 7 [ansible] 8 name=ansible_repo 9 baseurl=ftp://192.168.1.254/ansible 10 enabled=1 11 gpgcheck=0
二、在ansible管理机器上安装ansible
[root@ansible ~]# yum install ansible -y
三、查看ansible的版本信息
1 [root@ansible ~]# ansible --version 2 ansible 2.4.2.0 3 config file = /etc/ansible/ansible.cfg 4 configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules'] 5 ansible python module location = /usr/lib/python2.7/site-packages/ansible 6 executable location = /usr/bin/ansible 7 python version = 2.7.5 (default, Aug 4 2017, 00:39:18) [GCC 4.8.5 20150623 (Red Hat 4.8.5-16)]
四、配置主机名解析：
1 [root@ansible ~]# vim /etc/hosts 2 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 3 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 4 192.168.1.10 ansible 5 192.168.1.11 web1 6 192.168.1.12 web2 7 192.168.1.21 db1 8 192.168.1.22 db2 9 192.168.1.33 cache
[root@ansible ~]# for i in 11 12 21 22 33; do scp /etc/hosts 192.168.1.${i}:/etc/; done
[root@ansible ~]# ssh-keygen -t rsa -b 2048 -N ''
五、修改配置文件：
1 [root@ansible ~]# vim /etc/ssh/ssh_config 2 StrictHostKeyChecking no //禁止首次登录时交互验证
1 [root@ansible ~]# vim /etc/ansible/ansible.cfg 2 inventory = /etc/ansible/hosts //去掉注释，指定主机分组的配置文件
六、指定ansible管理的主机分组：
1 [root@ansible ~]# vim /etc/ansible/hosts 2 [web] 3 web[1:2] 4 5 [db] 6 db1 7 db2 8 9 [app:children] 10 web 11 db 12 13 [app:vars] 14 ansible_ssh_user="root" //授权远程登陆管理主机的用户 15 ansible_ssh_pass="123456" //授权远程登陆管理主机的用户密码 16 ansible_ssh_port="22" //端口设置 17 18 [other] 19 cache ansible_ssh_user="root" ansible_ssh_pass="123456"
七、给所有主机部署密钥
1 [root@ansible ~]# ansible all -m authorized_key -a "user=root exclusive=true manage_dir=true key='$(< /root/.ssh/id_rsa.pub)'" -k
八、测试：
1 [root@ansible ~]# ansible all -m ping 2 db2 | SUCCESS => { 3 "changed": false, 4 "ping": "pong" 5 } 6 web1 | SUCCESS => { 7 "changed": false, 8 "ping": "pong" 9 } 10 db1 | SUCCESS => { 11 "changed": false, 12 "ping": "pong" 13 } 14 cache | SUCCESS => { 15 "changed": false, 16 "ping": "pong" 17 } 18 web2 | SUCCESS => { 19 "changed": false,
至此，ansible基本就部署完成了！！！
