使用ansible這台主機來跑佈屬流程
原始碼管理(連接Gitlab)
##### Gitlab複製下來的clone
http://gitlab.jimmyhome.tw/root/redis-config-test.git
##### Credential
連接gitlab帳號和密碼
Invoke Ansible Playbook
##### ansible腳本位置
Playbook path: /root/ansible/se_redis-config-test_deploy.yml
##### Inventory主機IP
以下撰寫方式，ip都會傳入
連接要佈屬的主機，使用帳號，我這裡用key，
所以我有從ansible主機，產生key，ssh-copy-id 要佈屬的主機
[root@ansible ~]# ssh-copy-id 192.168.1.11
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
root@192.168.1.11's password:
Number of key(s) added: 1
Now try logging into the machine, with: "ssh '192.168.1.11'"
and check to make sure that only the key(s) you wanted were added.
[root@ansible ~]# ssh-copy-id 192.168.1.12
[root@ansible ~]# ssh-copy-id 192.168.1.13
[root@ansible ~]# ssh-copy-id 192.168.1.14
Jenkins參數，要傳入ansible內
Extra Variables
可以看到，zone選擇，function也會跟著變動
輸入IP處，slaveip可以輸入多個
可以看到，redis-sentinel已經成功啟動，有偵測到目前master是誰，也偵測到slaves主機有3台，總共4台主機啟動sentinel服務
進redis主機直接確認，使用redis-cli登入，選擇index 1，
set 1個key為test value為1
get key test，value為1
[root@redis01 redis]# redis-cli
127.0.0.1:6379> select 1
OK
127.0.0.1:6379[1]> set test 1
OK
127.0.0.1:6379[1]> get test
"1"
[root@redis01 redis]# redis-cli -p 26379
master0:name=search,status=ok,address=192.168.1.11:6379,slaves=3,sentinels=4
可以看到，如果再次佈屬，會顯示失敗，因為主機redis和redis-sentinel服務如果是active狀態，就不能佈屬(腳本一開始就有添加此段），
防止輸入IP輸錯，導致設定檔覆蓋，營運中的redis服務異常
