1 .使用root用户登录
2.执行use mysql指令
3.新增用户并赋权限
*.*===>database.table,即数据库名称和表名称
zcloud===>指定用户名,如果数据库中有该用户名,则更新,没有则为新增用户
@后的字符串表示允许远程登录的主机,常用的如localhost表示本地主机,%表示任意主机,如需指定登录主机的话,可使用IP地址。
'Passw0rd'用户密码,指定用户的登录密码,自定义任意字符。
4.保存,flush privileges
5.重启mysql服务
6.修改mysql的配置文件,不同的版本对应的文件不一样,可能是my.cnf,也可能是mysqld.conf.d
找到 bind-address = 127.0.0.1的一行,在前面加#注释掉即可
配置文件参考如下
mysqld.conf.d
6.OK,可以使用客户端进行访问了。
