部署步驟
-
創建目錄結構并添加上述配置文件
-
設置正確的文件權限（避免之前的權限問題）
chmod -R 644 config/
- 啟動容器
docker-compose up -d
- 驗證部署
# 檢查容器狀態
docker-compose ps# 連接到主節點查看信息
docker exec -it redis-master redis-cli info replication# 連接到從節點1查看信息
docker exec -it redis-slave1 redis-cli -p 6380 info replication# 連接到從節點2查看信息
docker exec -it redis-slave2 redis-cli -p 6381 info replication
測試主從復制
- 在主節點設置一個鍵值
docker exec -it redis-master redis-cli
127.0.0.1:6379> SET mykey "Hello from master"
OK
- 在從節點讀取該鍵值
# 從節點1
docker exec -it redis-slave1 redis-cli -p 6380
127.0.0.1:6380> GET mykey
"Hello from master"# 從節點2
docker exec -it redis-slave2 redis-cli -p 6381
127.0.0.1:6381> GET mykey
"Hello from master"
