一·、批量推送公鑰
1.使用 ssh-keygen -t rsa生成密鑰對
ssh-keygen -t rsa
2.推送單個公鑰到遠端機器
格式： ssh-copy-id -i ~/.ssh/id_rsa.pub username@[ip,hostname]
ssh-copy-id -i ~/.ssh/id_rsa.pub [email protected]
3.添加ansible hosts
編輯/etc/ansible/hosts,沒有則建立些檔案。
格式：【主機名】 【主機位址】 【主機密碼】 預設是root使用者來進行的
[all]
1 ansible_ssh_user="root" ansible_ssh_host=192.168.198.131 ansible_ssh_pass="123456"
2 ansible_ssh_user="root" ansible_ssh_host=192.168.198.134 ansible_ssh_pass="123456"
3 ansible_ssh_user="root" ansible_ssh_host=192.168.198.141 ansible_ssh_pass="123456"
新版的ansible(2.4) hosts有更新， 用以下方式：
192.168.198.131 ansible_user=root ansible_ssh_pass="123456"
192.168.198.141 ansible_user=root ansible_ssh_pass="123456"
192.168.198.134 ansible_user=root ansible_ssh_pass="123456"
4.批量推送公鑰到遠端機器
[root@mha ansible]# ls
ansible.cfg hosts push.ssh.ymal roles
[root@mha ansible]# cat push.ssh.ymal
hosts: all
user: root
tasks:
name: ssh-copy
authorized_key: user=root key="{{ lookup('file', '/root/.ssh/id_rsa.pub') }}"
tags:
sshkey
5.執行推送指令
ansible-playbook push.ssh.ymal
[root@mha ansible]# ansible-playbook push.ssh.ymal
PLAY [all] **
TASK [Gathering Facts] **
ok: [192.168.198.134]
ok: [192.168.198.141]
ok: [192.168.198.131]
TASK [ssh-copy] *****
changed: [192.168.198.131]
PLAY RECAP **
192.168.198.131 : ok=2 changed=1 unreachable=0 failed=0
192.168.198.134 : ok=2 changed=0 unreachable=0 failed=0
192.168.198.141 : ok=2 changed=0 unreachable=0 failed=0
二·、檢查主機組或者是單一個主機
[root@mha ansible-tower-setup-3.1.0]# ansible all -m shell -a "mysql -uroot -p123456 -e 'use test;show tables'"
192.168.198.134 | SUCCESS | rc=0 >>
Tables_in_test
t3
t4
t44
t5
tt1
192.168.198.131 | FAILED | rc=127 >>
/bin/sh: mysql: command not found
192.168.198.141 | SUCCESS | rc=0 >>
hosts: 192.168.198.131
gather_facts: no
name: mkdir code.
shell: mkdir /root/600
name: git pull the code.
git: [email protected]:wsw26/600.git dest=/root/600/
git:
repo: [email protected]:wsw26/600.git
dest: /root/600/
version: v1.9.306
客戶機能順利把代碼拉下來并切換分支了
四、ansible-tower
