MySQL的一些配置问题

在使用MySQL时候,常常会遇到一些奇葩的问题,简单梳理一下

1、服务器端搭建MySQL服务器不允许远程连接

第一步:服务器端在防火墙中开启MySQL3306端口,在cmd中输入下面命令:

netsh firewall add portopening protocol = TCP port = 3306 name = "Open3306" mode =Enable

这样在防火墙的入站规则中就可以看到“Open3306”

第二步:开启MySQL的远程访问

登录服务器端的MySQL(无论是用命令行方式,还是用客户端如navicat方式),找到mysql数据库,找到user表,将user表中的字段Host的值由“localhost”改为“%”

第三步:重启MySQL服务


2、MySQL无法插入中文

有的时候我们在创建数据库的时候,已经设置了MySQL的编码为utf8,此时在读取数据库的时候已经不会出现中文乱码,以为万无一失了,但是在开发过程中发现,数据库竟然出现“不允许插入中文”的奇葩问题,这个时候应该如何配置?答案是修改my.ini文件,如下。

打开my.ini文件(在mysql安装的根目录),修改两处,分别是client和server的编码格,如下图

此处是设置client的编码


此处时设置server端编码


至此,中文不能插入的问题解决。
