MySQL守护进程拒绝以"无法启动服务器:在TCP/IP端口上绑定:已在使用的地址"(它不是)开始.

Question

好吧,伙计们,我已经准备好放弃这件事了,我想我差点就在那里,只是最后一个错误,服务器启动很好,但是后来它说没有说TCP/IP端口上的绑定已经在使用:S哪个不正确,因为mysql没有运行:(

错误:

使用lsof -i TCP:3306或netstat -lp | grep 3306找出已经在端口3306上侦听的内容 - 必须要听取它.

您可以考虑在不同的端口上启动服务器(编辑my.cnf并更改默认端口).

您可能需要以root身份运行它,即 sudo lsof -i TCP:3306
