一、playbook檔案redis.yaml
--- - hosts: test vars_files: - vars.yml remote_user: "{{user}}" become: yes tasks: - name: "安裝epel源" command: yum -y install epel-release - name: "安裝redis" yum: name: redis state: latest - name: "修改redis配置檔案監聽IP為本機" lineinfile: path: /etc/redis.conf regexp: '^bind 127' line: bind {{master_redis}} - name: "設定開機啟動" service: name: redis enabled: yes - name: "啟動主庫redis6379埠" service: name: redis state: started - name: "製作從庫配置檔案" command: cp /etc/redis.conf /etc/redis_slave.conf - name: "建立從庫的資料存放位置" command: mkdir -p /var/lib/redis_slave - name: "編輯從庫配置檔案的繫結IP" lineinfile: path: /etc/redis_slave.conf regexp: '^bind 127' line: bind {{master_redis}} - name: "編輯從庫配置檔案的資料存放位置" lineinfile: path: /etc/redis_slave.conf regexp: '^dir /var/lib/redis' line: dir /var/lib/redis_slave - name: "編輯從庫配置檔案的監聽埠" lineinfile: path: /etc/redis_slave.conf regexp: '^port 6379' line: port 7777 - name: "編輯從庫的配置檔案，設定為從庫" lineinfile: path: /etc/redis_slave.conf line: slaveof "{{master_redis}}" 6379 - name: "啟動從庫" shell: nohup redis-server /etc/redis_slave.conf &
二、外部變數檔案vars.yml
[root@Ansible playbook]# cat vars.yml
user: cedar
master_redis: 10.3.153.8三、安裝結果
