docker-compose啟動redis主從的實現(xiàn)

更新時間：2026年07月14日 09:35:57 作者：玄德公筆記

本文主要介紹了docker-compose啟動redis主從的實現(xiàn),文中通過示例代碼介紹的非常詳細,對大家的學習或者工作具有一定的參考學習價值,需要的朋友們下面隨著小編來一起學習學習吧

環(huán)境說明：

IP	主機名	服務(wù)
10.xxx.91.100	liubei	redis-master
10.xxx.91.101	liubei02	redis-slave

1. 主節(jié)點

創(chuàng)建redis-m 目錄，并進入該目錄
創(chuàng)建 docker-compose.yml文件內(nèi)容如下：

version: '3'
services:
  redis-master:
    image: redis:7.4
    container_name: redis-master
    command: ["redis-server", "/usr/local/etc/redis/redis.conf", "--appendonly", "yes"]
    ports:
      - "6379:6379"
    volumes:
      - ./data:/data
      - ./redis.conf:/usr/local/etc/redis/redis.conf
    restart: always

創(chuàng)建redis.conf文件（至少644權(quán)限）。內(nèi)容如下：

bind 0.0.0.0
port 6379
requirepass KrhLSx2XVs
masterauth  KrhLSx2XVs
appendonly yes

說明：

requirepass 是客戶端訪問從節(jié)點時的密碼。
masterauth 是從節(jié)點連接主節(jié)點時使用的密碼。
replicaof 告訴從節(jié)點同步主節(jié)點的數(shù)據(jù)

2. 從節(jié)點配置

創(chuàng)建redis-s 目錄，并進入該目錄
創(chuàng)建 docker-compose.yml文件內(nèi)容如下：

version: '3'
services:
  redis-slave:
    image: harbocto.xxx.com.cn/public/redis:7.4
    container_name: redis-slave
    command: ["redis-server", "/usr/local/etc/redis/redis.conf", "--appendonly", "yes"]
    ports:
      - "6379:6379"
    volumes:
      - ./data:/data
      - ./redis.conf:/usr/local/etc/redis/redis.conf
    restart: always

創(chuàng)建redis.conf文件（至少644權(quán)限）。內(nèi)容如下：

bind 0.0.0.0
port 6379
requirepass KrhLSx2XVs
masterauth  KrhLSx2XVs
replicaof 10.xxx.91.100 6379
appendonly yes

3. 啟動集群

起來就行，不需要過多操作

啟動master

[root@liubei redis-m]# docker-compose up -d
Creating network "redis-m_default" with the default driver
Creating redis-master ... done
[root@liubei redis-m]# docker-compose ps
    Name                  Command               State           Ports
------------------------------------------------------------------------------
redis-master   docker-entrypoint.sh redis ...   Up      0.0.0.0:6379->6379/tcp

啟動slave

[root@liubei02 redis-02]# docker-compose up -d
Creating network "redis-02_default" with the default driver
Creating redis-slave ... done
[root@liubei02 redis-02]# docker-compose ps
   Name                  Command               State           Ports
-----------------------------------------------------------------------------
redis-slave   docker-entrypoint.sh redis ...   Up      0.0.0.0:6379->6379/tcp

4. 驗證

4.1 驗證狀態(tài)

主節(jié)點上

[root@liubei redis-m]# docker exec -it redis-master redis-cli -a KrhLSx2XVs info replication
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
# Replication
role:master
connected_slaves:1
slave0:ip=10.xxx.91.101,port=6379,state=online,offset=1386,lag=0
master_failover_state:no-failover
master_replid:3c049bf4538faf754c56c7e2bd5ac40a217b661a
master_replid2:0000000000000000000000000000000000000000
master_repl_offset:1386
second_repl_offset:-1
repl_backlog_active:1
repl_backlog_size:1048576
repl_backlog_first_byte_offset:1
repl_backlog_histlen:1386

從節(jié)點上驗證

[root@finaichat-prd-web12 redis-02]# docker exec -it redis-slave redis-cli -a KrhLSx2XVs info replication
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
# Replication
role:slave
master_host:10.xxx.91.100
master_port:6379
master_link_status:up
master_last_io_seconds_ago:2
master_sync_in_progress:0
slave_read_repl_offset:1568
slave_repl_offset:1568
slave_priority:100
slave_read_only:1
replica_announced:1
connected_slaves:0
master_failover_state:no-failover
master_replid:3c049bf4538faf754c56c7e2bd5ac40a217b661a
master_replid2:0000000000000000000000000000000000000000
master_repl_offset:1568
second_repl_offset:-1
repl_backlog_active:1
repl_backlog_size:1048576
repl_backlog_first_byte_offset:1
repl_backlog_histlen:1568

4.2 讀寫驗證

主節(jié)點寫入

[root@liubei ~]# docker exec -it redis-master redis-cli -a KrhLSx2XVs
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
127.0.0.1:6379> SET key1 liubei
OK

從節(jié)點讀取

[root@liubei01 ~]# docker exec -it redis-slave redis-cli -a KrhLSx2XVs
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
127.0.0.1:6379> get key1
"liubei"
