ansible批量部署Redis

一、目录环境

[root@wd-code deploy_redis]# tree
.
├── file
│   ├── redis-4.0.13.tar.gz
│   └── redis.conf.j2
├── hosts
└── redis.yml

1 directory, 4 files

二、file目录

file目录下存放redis包与redis.conf.j2配置文件

redis.conf.j2配置如下：

bind 127.0.0.1  {{ ansible_default_ipv4.address }}
protected-mode yes
port 6379
tcp-backlog 511
timeout 0

client-output-buffer-limit slave 256mb 64mb 60
client-output-buffer-limit pubsub 32mb 8mb 60

aof-rewrite-incremental-fsync yes

三、hosts文件

[redis]
10.128.31.42 ansible_ssh_user=root ansible_ssh_pass=xxxx

四、redis.yml文件

---
- hosts: redis
  remote_user: work
  vars:
    redis_data_dir: /home/work/redis/data
    var_dir: /home/work/redis
    unarch: /home/work
    redis_dir: /home/work/redis-4.0.13
  tasks:
    - name: 创建redis数据目录
      file: path={{ redis_data_dir }} state=directory

    - name: 复制redis包到远程主机
      copy: src=./file/redis-4.0.13.tar.gz dest=/tmp

    - name: 解压包
      unarchive:
        src: /tmp/redis-4.0.13.tar.gz
        dest: "{{ unarch }}"
        copy: no

    - name: 安装
      shell: cd {{ unarch }}/redis-4.0.13 && make

    - name: 创建二进制目录配置文件目录
      shell: cd {{ var_dir }} && mkdir -pv bin conf

    - name: cp 编译完成的二进制文件到bin和conf下配置文件
      shell: cp {{ redis_dir }}/src/redis-* {{ var_dir }}/bin && rm -rf {{ var_dir }}/bin/*.c && rm -rf {{ var_dir }}/bin/*.o

    - name: 拷贝编译完成的redis.conf文件到conf下
      template: src=./file/redis.conf.j2 dest={{ var_dir }}/conf/redis.conf

    - name: 启动redis
      shell: "{{ var_dir }}/bin/redis-server {{ var_dir }}/conf/redis.conf"

    - name: 删除redis解压包
      file: path={{ redis_dir }} state=absent

五、执行剧本

ansible-playbook -i hosts redis.yml
