Linux 7 安装 Ansible 并作基本的配置
安装前提条件：控制服务器可以通过 ssh 免密登录被控制服务器。
一、安装 Ansible

[root@xiejiaohui ~]#
二、修改配置文件ansible.cfg
[root@workstation ~]# su - student [student@workstation ~]$ cd [student@workstation ~]$ pwd /home/student [student@workstation ~]$ mkdir ansible [student@workstation ~]$ cd ansible/ [student@workstation ansible]$ cp /etc/ansible/ansible.cfg /home/student/ansible/ [student@workstation ansible]$ vim ansible.cfg [student@workstation ansible]$ cat ansible.cfg |grep -v ^#|grep -v ^$ [defaults] inventory = /home/student/ansible/inventory ask_pass = False roles_path = /home/student/ansible/roles:/etc/ansible/roles:/usr/share/ansible/roles remote_user = student [inventory] [privilege_escalation] become=True become_method=sudo become_user=root become_ask_pass=False [paramiko_connection] [ssh_connection] [persistent_connection] [accelerate] [selinux] [colors] [diff] [student@workstation ansible]$
三、配置 inventory 文件
[student@workstation ansible]$ vim inventory [student@workstation ansible]$ cat inventory [dev] servera [test] serverb [prod] serverc serverd [webservers:children] prod [student@workstation ansible]$
四、修改客户端 sudoers 文件
登录被控制的电脑
$ssh root@servera
servera 修改文件 /etc/sudoers 在最后新增一行
student ALL=(ALL) NOPASSWD: ALL
## Read drop-in files from /etc/sudoers.d (the # here does not mean a comment) #includedir /etc/sudoers.d student ALL=(ALL) NOPASSWD: ALL
五、验证是否配置正确，通过ping 命令测试
[student@workstation ansible]$ ansible all -m ping servera | SUCCESS => { "changed": false, "ping": "pong" } serverb | SUCCESS => { "changed": false, "ping": "pong" } serverc | SUCCESS => { "changed": false, "ping": "pong" } serverd | SUCCESS => { "changed": false, "ping": "pong" } [student@workstation ansible]$ ansible dev -m ping servera | SUCCESS => { "changed": false, "ping": "pong" } [student@workstation ansible]$ ansible test -m ping serverb | SUCCESS => { "changed": false, "ping": "pong" } [student@workstation ansible]$ ansible prod -m ping serverd | SUCCESS => { "changed": false, "ping": "pong" } serverc | SUCCESS => { "changed": false, "ping": "pong" } [student@workstation ansible]$ ansible webservers -m ping serverd | SUCCESS => { "changed": false, "ping": "pong" } serverc | SUCCESS => { "changed": false, "ping": "pong" } [student@workstation ansible]$
列出所有主机
[student@workstation ansible]$ ansible all --list-hosts hosts (4): servera serverb serverc serverd [student@workstation ansible]$
