Mac Homebrew安装的MySQL无法远程登录的解决

目录

• 1. 登录mysql
• 2. 修改user表中root用户的Host值
• 3. 刷新权限
• 4. 退出MySQL
• 5. 修改MySQL服务绑定的IP
• 6. 重启MySQL服务

对于M编程客栈ac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开发者_MsSql程主机访问。

1. 登录MySQL

mysql -u root -p -D mysql

2. 修改user表中root用户的Host值

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    | localho编程客栈st |
+------------------+-----------+
4 rows in set (0.00 sec)

3. 刷新权限

flush privileges;

4. 退出MySQL

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：

# Default Homebrew MySQL server config
[javascriptmysqld]
# Only allow connections from localhost
bind-address = 127.0.0.1
mysqlx-bind-address = 127.0.0.1

将bind-address值修改为0.0.0.0：

# Default Homebrew MySQL server config
[mysqld]
# Only allow connections from local编程host
bind-address = 0.0.0.0
mysqlx-bind-address = 127.0.0.1

6. 重启MySQL服务

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

验证

$ mysql -u root -p -h 192.168.0.100
Enter password:
