问题原因

查看mysql日志发现存在下面的信息：

151030 12:16:15 [Note] Plugin 'FEDERATED' is disabled.
151030 12:16:15  InnoDB: Initializing buffer pool, size = 8.0M
151030 12:16:15  InnoDB: Completed initialization of buffer pool
151030 12:16:15  InnoDB: Started; log sequence number 0 58944

151030 12:16:16 [ERROR] TCP/IP, --shared-memory, or --named-pipe should be configured on NT OS
151030 12:16:16 [ERROR] Aborting

错误主要在以下这条日志。

TCP/IP, --shared-memory, or --named-pipe should be configured on NT OS

解决方案

查看my.ini配置文件，发现最后在最my.ini后面多了一个 skip-networking

注释掉 #skip-networking 后重启启动恢复正常。
