问题:in C# Redis : could not connect to redis Instance at 127.0.0.1:6379 (有时候访问不了,刷新又可访问)
使用的是ServiceStack.redis 版本 2.2 ,据说版本4+ 要收费。
代码:开始用 var result=new RedisClient("127.0.0.1",6379,1"1111");
后面改为连接池(集群的方式) /// <summary> /// 连接客户端管理 /// </summary> private static PooledRedisClientManager prcm; /// <summary> /// 创建链接池管理对象 /// </summary> public static PooledRedisClientManager CreateManager() { string[] writeServerList = SplitString(redisConfigInfo.WriteServerList, ","); string[] readServerList = SplitString(redisConfigInfo.ReadServerList, ","); return new PooledRedisClientManager(writeServerList, readServerList, new RedisClientManagerConfig { MaxWritePoolSize = redisConfigInfo.MaxWritePoolSize, MaxReadPoolSize = redisConfigInfo.MaxReadPoolSize, DefaultDb = redisConfigInfo.InitalDb, AutoStart = redisConfigInfo.AutoStart, }); //, redisConfigInfo.InitalDb } /// <summary> /// 客户端缓存操作对象 /// </summary> public static IRedisClient GetClient() { if (OpenRedis) { if (prcm == null) { prcm = CreateManager(); } return prcm.GetClient(); } return null; } 但发现用同一个还是连接池并发大还是有问题,从日志上面看 Redis Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use. 异常信息:System.TimeoutException: Redis Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use. could not connect to redis Instance at 127.0.0.1:6379 异常信息:ServiceStack.Redis.RedisException: could not connect to redis Instance at 127.0.0.1:6379 ---> System.Net.Sockets.SocketException: 在一个非套接字上尝试了一个操作。 127.0.0.1:6379 后面在网上查找的时候看到使用using 的方法。 跟连接数据库一样的道理,还有开多线程会报错,要加local锁 RedisConfigInfo类 using System;
