listenInCluster函数传入了各种参数,如server实例、ip、port、ip类型(IPv6和IPv4)、backlog(底层服务端socket处理请求的最大队列)、fd等,它们不是必须传入,比如创建一个TCP服务器,就仅仅需要一个port即可。 简化后的listenInCluster函数很简单,cluster模块判断当前进程为主进程时,执行_listen2函数;否则,在子进程...
Because this file might be in use, it was not replaced, but was used in bootstrap (unless you used –defaults-file) and when you later start the server. The new default config file was created as /opt/mysql/server-5.6/my-new.cnf, please compare it with your file and take the change...
