对于Mac上Homebrew安装的MySQL，默认情况下只能使用本地登录。
而使用其它主机远程登录Mac上的MySQL则会被拒绝访问。
下面修改MySQL的相关配置并使其能被远程主机访问。
1. 登录MySQL
|
1
|
mysql -u root -p -D mysql |
2. 修改user表中root用户的Host值
|
1
|
update user set host='%' where user='root'; |
查看下修改情况：

mysql> select user,host from user;+------------------+-----------+| user | host |+------------------+-----------+| root | % || mysql.infoschema | localhost || mysql.session | localhost || mysql.sys | localhost |+------------------+-----------+4 rows in set (0.00 sec) |
3. 刷新权限
|
1
|
flush privileges; |
4. 退出MySQL
|
1
|
exit |
5. 修改MySQL服务绑定的IP
对于Homebrew安装的MySQL，默认的配置文件路径是/usr/local/etc/my.cnf：
|
1

3
4
5
|
# Default Homebrew MySQL server config[mysqld]# Only allow connections from localhostbind-address = 127.0.0.1mysqlx-bind-address = 127.0.0.1 |
将bind-address值修改为0.0.0.0：
|
1
2
3
4
5
|
# Default Homebrew MySQL server config[mysqld]# Only allow connections from localhostbind-address = 0.0.0.0mysqlx-bind-address = 127.0.0.1 |
6. 重启MySQL服务
|
1
|
brew services restart mysql |
如果brew重启失败，有以下两种解决方案：
进入/usr/local/Cellar/mysql/<version>/bin目录下，使用mysql.server restart命令重启MySQL。注意"version"是你Mac上安装MySQL的版本号，请根据实际安装版本号来替换
可以选择重启Mac来达到重启MySQL服务的目的。重启Mac后，如果没有设置MySQL服务自启动，需要手动拉起MySQL服务：mysql.server start

远程登录成功。
以上为个人经验，希望能给大家一个参考，也希望大家多多支持服务器之家。
