笔记二：ansible批量设置主机名

标签：ansible改名

1. 在/etc/ansible/hosts配置主机信息(主机名需先在hosts设置好)

zhaojia@sredev2:~$ cat /etc/ansible/hosts # This is the default ansible ‘hosts‘ file. # # It should live in /etc/ansible/hosts # ......省略内容 [test] 218.60.33.2 hostname=cdnsy-junheng0.cdnsy ansible_ssh_port=22 ansible_ssh_user=root ansible_ssh_pass=xxx 218.60.33.3 hostname=cdnsy-junheng1.cdnsy ansible_ssh_port=22 ansible_ssh_user=root ansible_ssh_pass=xxx 218.60.33.4 hostname=cdnsy-junheng2.cdnsy ansible_ssh_port=22 ansible_ssh_user=root ansible_ssh_pass=xxx 218.60.33.5 hostname=cdnsy-junheng3.cdnsy ansible_ssh_port=22 ansible_ssh_user=root ansible_ssh_pass=xxx ————————————————————————————————————— 主机ip+ hostname+ 端口port+ 登录用户root+ 登录密码

2.修改主机名playbook

zhaojia@sredev2:~$ cat name.yml  --- - hosts: test   remote_user: root   tasks:      - name: change name        raw: "echo {{hostname|quote}} > /etc/hostname"      - name:         shell: hostname {{hostname|quote}}

3. 执行playbook

zhaojia@sredev2:~$ ansible-playbook name.yml  [WARNING]: log file at /var/log/ansible.log is not writeable and we cannot create it, aborting PLAY [test] **************************************************************** TASK [setup] ******************************************************************* ok: [218.60.33.2] ok: [218.60.33.3] ok: [218.60.33.4] ok: [218.60.33.5] TASK [change name] ************************************************************* changed: [218.60.33.2] changed: [218.60.33.3] changed: [218.60.33.4] changed: [218.60.33.5] TASK [command] ***************************************************************** changed: [218.60.33.2] changed: [218.60.33.3] changed: [218.60.33.4] changed: [218.60.33.5] PLAY RECAP ********************************************************************* 218.60.33.2               : ok=5    changed=4    unreachable=0    failed=0    218.60.33.3               : ok=5    changed=4    unreachable=0    failed=0 218.60.33.4               : ok=5    changed=4    unreachable=0    failed=0    218.60.33.5               : ok=5    changed=4    unreachable=0    failed=0

4. 查看被管理机的主机名

zhaojia@sredev2:~$ ansible test -m shell -a "hostname" 218.60.33.2 | SUCCESS | rc=0 >> cdnsy-junheng0.cdnsy 218.60.33.3 | SUCCESS | rc=0 >> cdnsy-junheng1.cdnsy 218.60.33.4 | SUCCESS | rc=0 >> cdnsy-junheng2.cdnsy 218.60.33.5 | SUCCESS | rc=0 >> cdnsy-junheng3.cdnsy
