Replication 集群同步原理 当我们在 Master 节点写入数据,Master 会把这次操作会记录到 binlog 日志里边,Slave 节点会有专门的线程去请求 Master 发送 binlog 日志,然后 Slave 节点上的线程会把收到的 Master 日志记录在本地 realy_log 日志文件中,slave 节点通过执行 realy_log 日志来实现数据的同步,最后把执行过...

int listen(int sockfd, int backlog); Sockfd是Socket系统调用返回的socket 描述符;backlog指定在请求队列中允许的最大请求数,进入的连接请求将在队列中等待accept()它们(参考下文)。Backlog对队列中等待服务的请求的数目进行了限制,大多数系统缺省值为20。如果一个服务请求到来时,输入队列已满,该socket将拒绝连接...
