Ansible 之 自動化部署redis主從(單機)

一、playbook文件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配置文件監聽IP爲本機"
      lineinfile:
        path: /etc/redis.conf
        regexp: '^bind 127'
        line: bind {{master_redis}}
    - name: "設置開機啓動"
      service:
        name: redis
        enabled: yes
    - name: "啓動主庫redis6379端口"
      service:
        name: redis
        state: started
    - name: "製作從庫配置文件"
      command: cp /etc/redis.conf /etc/redis_slave.conf
    - name: "創建從庫的數據存放位置"
      command: mkdir -p /var/lib/redis_slave
    - name: "編輯從庫配置文件的綁定IP"
      lineinfile:
        path: /etc/redis_slave.conf
        regexp: '^bind 127'
        line: bind {{master_redis}}
    - name: "編輯從庫配置文件的數據存放位置"
      lineinfile:
        path: /etc/redis_slave.conf
        regexp: '^dir /var/lib/redis'
        line: dir /var/lib/redis_slave
    - name: "編輯從庫配置文件的監聽端口"
      lineinfile:
        path: /etc/redis_slave.conf
        regexp: '^port 6379'
        line: port 7777
    - name: "編輯從庫的配置文件，設置爲從庫"
      lineinfile:
        path: /etc/redis_slave.conf
        line: slaveof "{{master_redis}}" 6379
    - name: "啓動從庫"
      shell: nohup redis-server /etc/redis_slave.conf &

二、外部變量文件vars.yml

[root@Ansible playbook]# cat vars.yml 
user: cedar
master_redis: 10.3.153.8

三、安裝結果

[root@Ansible playbook]# ansible-playbook redis.yaml
