redis哨兵模式(一主二从三哨兵)

作者：互联网

 首先 准备一个配置文件路径 

mkdir /usr/local/etc/redis/sentinel/sentinel -p
  
cd /usr/local/etc/redis/sentinel/sentinel

配置三个哨兵的配置文件 我们设置端口 号 26379、26380 、26381

 

 

 

 配置主机点  

 

从节点的 配置 

 

 

 

 

 

 

 

运行 compose.yml 文件

文件存在  

cd /usr/local/etc/redis/sentinel/sentinel
  
vi docker-compose.yml






version: '3'

services:

  redis-sentinel-1:
5 
    image: redis
6 
    container_name: redis-sentinel-1
7 
    restart: always
8 
    # 为了规避Docker中端口映射可能带来的问题
9 
    # 这里选择使用host网络
10 
    network_mode: host
11 
    volumes:
12 
      - ./redis-sentinel-1.conf:/usr/local/etc/redis/redis-sentinel.conf
13 
    # 指定时区，保证容器内时间正确
14 
    environment:
15 
      TZ: "Asia/Shanghai"
16 
    command: ["redis-sentinel", "/usr/local/etc/redis/redis-sentinel.conf"]
17 
  redis-sentinel-2:
18 
    image: redis
19 
    container_name: redis-sentinel-2
20 
    restart: always
21 
    network_mode: host
22 
    volumes:
23 
      - ./redis-sentinel-2.conf:/usr/local/etc/redis/redis-sentinel.conf
24 
    environment:
25 
      TZ: "Asia/Shanghai"
26 
    command: ["redis-sentinel", "/usr/local/etc/redis/redis-sentinel.conf"]
27 
  redis-sentinel-3:
28 
    image: redis
29 
    container_name: redis-sentinel-3
30 
    restart: always
31 
    network_mode: host
32 
    volumes:
33 
      - ./redis-sentinel-3.conf:/usr/local/etc/redis/redis-sentinel.conf
34 
    environment:
35 
      TZ: "Asia/Shanghai"
36 
    command: ["redis-sentinel", "/usr/local/etc/redis/redis-sentinel.conf"]


在dockers 里面 运行 启动  

cd /usr/local/etc/redis/sentinel/server
docker-compose up -d
cd /usr/local/etc/redis/sentinel/sentinel
  
docker-compose up -d
  
#查看主从信息
info replication
 
测试
  
停止主节点
  
docker stop redis-server-master
  
​
  
#进入从1redis-server-slave-1查看角色是否被修过为主节点
  
docker exec -it redis-server-slave-1 /bin/bash
  
redis-cli -p 6380 -a 123456
  
info replication
  
​
  
#进入从1redis-server-slave-2查看角色是否被修过为主节点
  
docker exec -it redis-server-slave-2 /bin/bash
  
redis-cli -p 6381 -a 123456
  
info replication
