配置文件内容

1. `config/master.conf`

# Redis主节点配置
port 6379

protected-mode no
logfile "redis-master.log"
dir /data
save 900 1
save 300 10
save 60 10000

2. `config/slave1.conf`

# Redis从节点1配置
port 6380
bind 0.0.0.0
protected-mode no
logfile "redis-slave1.log"
dir /data
slaveof redis-master 6379

3. `config/slave2.conf`

# Redis从节点2配置
port 6381
bind 0.0.0.0
protected-mode no
logfile "redis-slave2.log"
dir /data
slaveof redis-master 6379

部署步骤

创建目录结构并添加上述配置文件
设置正确的文件权限（避免之前的权限问题）

chmod -R 644 config/

启动容器

docker-compose up -d

验证部署

# 检查容器状态
docker-compose ps# 连接到主节点查看信息
docker exec -it redis-master redis-cli info replication# 连接到从节点1查看信息
docker exec -it redis-slave1 redis-cli -p 6380 info replication# 连接到从节点2查看信息
docker exec -it redis-slave2 redis-cli -p 6381 info replication

测试主从复制

在主节点设置一个键值

docker exec -it redis-master redis-cli
127.0.0.1:6379> SET mykey "Hello from master"
OK

在从节点读取该键值

# 从节点1
docker exec -it redis-slave1 redis-cli -p 6380
127.0.0.1:6380> GET mykey
"Hello from master"# 从节点2
docker exec -it redis-slave2 redis-cli -p 6381
127.0.0.1:6381> GET mykey
"Hello from master"
