  • 我的redis是直接通过docker官方镜像创建的, 用了1个多月了都没事,今天在登录网站首页的时候发现拿不到登录验证码了, 看看报错信息.

idea控制台报的错误

错误分析

  • Spring Boot 应用在执行 Redis 写操作时遇到了 RedisReadOnlyException，提示 “READONLY You can’t write against a read only replica.”，意思是 当前 Redis 实例是只读的，从库（replica）无法执行写操作。

⸻

异常分析

1.	核心错误

Caused by: io.lettuce.core.RedisReadOnlyException: READONLY You can't write against a read only replica.

这是 Lettuce（Spring Boot 默认的 Redis 客户端）抛出的异常，表示应用试图在 只读的 Redis 副本（replica）上执行写入操作，但被拒绝。

2.	调用堆栈

at org.springframework.data.redis.core.DefaultValueOperations.set(DefaultValueOperations.java:253)
at com.chen.manager.service.impl.ValidateCodeServiceImpl.generateValidateCode(ValidateCodeServiceImpl.java:31)

generateValidateCode 方法尝试向 Redis 存入数据时失败了。

⸻
可能的原因
1. Redis 连接的是只读副本
• 你的 Spring Boot 连接的 Redis 实例可能是 只读从库，无法执行 SET 等写入操作。
• 如果你的 Redis 是主从模式（Master-Slave 或 Replica Set），并且 Spring Boot 连接到了 Slave（replica），写入请求就会失败。
2. Redis 主库（Master）失效或不可用
• 你的应用可能原本连接的是主库（Master），但主库宕机了，Redis 进入了 Failover（故障转移）模式，导致从库变成新的主库，而你的应用仍然连接的是原来的旧从库（现在变成了只读状态）。
3. Redis Sentinel 切换
• 如果你使用了 Redis Sentinel，它可能已经 将新的主库切换到别的节点，但应用的连接池还没有更新，导致它继续向旧的（现在是只读的）副本发送写入请求。
4. Spring Boot 配置错误
• 你的 Redis 配置可能错误地指定了一个 Replica，而不是 Master。

解决方案

方案 1：确保连接的是 Redis 主库

检查你的 Redis 连接配置，确保应用程序 连接的是 Redis 主库（Master），而不是副本：

spring:
  redis:
    host: <master-host>
    port: 6379

如果你是用 Redis 集群（Cluster），确保 spring.redis.cluster.nodes 指向正确的主节点。

方案 2：如果使用了 Sentinel，确保连接到正确的主库

如果你的 Redis 使用了 Sentinel，那么应该在 application.yml 配置：

spring:
  redis:
    sentinel:
      master: mymaster  # Sentinel 监控的主节点名称
      nodes: redis-sentinel-1:26379,redis-sentinel-2:26379,redis-sentinel-3:26379

这样，当 Redis 发生主从切换时，应用可以自动连接新的主库。

方案 3：检查 Redis 服务器状态

登录 Redis 服务器，执行以下命令：

redis-cli INFO replication

输出示例：

role:slave
master_host: 192.168.1.100
master_port: 6379

如果 role:slave，说明你连接的是 从库，需要改为主库的 IP 和端口。

方案 4：强制允许写入（不推荐）

如果你确定 Redis 只读模式不符合预期（比如误配置了从库），可以 手动在 Redis 上取消只读模式：

redis-cli

replicaof no one # 取消只读模式，让当前节点成为主库
CONFIG SET replica-read-only no

⚠️ 注意：这会导致主从模式失效，仅适用于本地调试！

方案 5：检查 Spring Boot 代码

如果你的代码支持读写分离，可以检查 RedisTemplate 或 StringRedisTemplate 的使用：

@Autowired
private RedisTemplate<String, String> redisTemplate;

public void saveData(String key, String value) {
redisTemplate.opsForValue().set(key, value); // 确保这里的 redisTemplate 连接的是主库
}

如果 redisTemplate 指向的是 从库，可以调整 RedisTemplate 配置，让它连接 Master。

⸻
总结

✅ 优先检查 Redis 服务器，确保你的应用连接的不是 只读副本（replica）。
✅ 如果 Redis 使用了主从模式或 Sentinel，应用应该连接 Master，而不是 Slave。
✅ 如果是 Spring Boot 代码问题，检查 RedisTemplate 是否正确配置为主库。

我的问题:进入redis容器看看日志

#进入容器
docker exec -it  redis  /bin/ bash
#查看日志
redis-cli INFO replication
#日志的信息
# Replication
role:slave
master_host:120.24.6.73
master_port:23334
master_link_status:down
master_last_io_seconds_ago:-1
master_sync_in_progress:0
slave_read_repl_offset:0
slave_repl_offset:0
master_link_down_since_seconds:-1

slave_read_only:1

second_repl_offset:1
repl_backlog_active:0
repl_backlog_size:1048576
repl_backlog_first_byte_offset:0
repl_backlog_histlen:0
  1. Redis 处于只读模式
    slave_read_only:1 说明从节点默认是只读的，不能执行写操作。
    2. 主节点连接已断开
    master_link_status:down，表明从节点无法连接到主节点 120.24.6.73:23334，因此无法同步数据。
    3. 无主从同步进行
    master_last_io_seconds_ago:-1 和 master_sync_in_progress:0 说明已经长时间未同步数据。
    4. 没有可用的主节点
    connected_slaves:0 表明当前没有连接到其他 Redis 实例。

解决方案1

这里直接把自己升级为主节点

redis -cli
slaveof no one
  • 在重新连接就可以了 这么设置redis一重启就失效了, 还后还要反复操作. 可以直接采用下面配置文件的方式

解决方案2设置redis 永远不为从, 编辑你挂载的配置文件

  • 找到你挂载的配置文件
docker inspect redis

在这里插入图片描述

  • 修改配置文件 ,添加一句
    vim 配置文件名
    i 进入插入模式
    esc :wq 保存并退出
replicaof no one
  • 重启 redis 永久生效,就在也不会报这个错误了
docker restart redis-server
