Homebrew安装mysql

Mac 安装mysql

安装

1. 查找可用的安装包

➜  ~ brew search mysql
==> Formulae
automysqlbackup            [email protected]           [email protected]
mysql ✔                    mysql-connector-c++        [email protected]
mysql++                    mysql-sandbox              mysqltuner
mysql-client               mysql-search-replace       qt-mysql

2. 安装

这里我们选择最新版本

➜  ~ brew install mysql
==> Caveats
We've installed your MySQL database without a root password. To secure it run:
    mysql_secure_installation

MySQL is configured to only allow connections from localhost by default

To connect run:
    mysql -uroot

To restart mysql after an upgrade:
  brew services restart mysql
Or, if you don't want/need a background service you can just run:
  /usr/local/opt/mysql/bin/mysqld_safe --datadir=/usr/local/var/mysql

3. 启动mysql

brew services start mysql

默认账号：root，无密码

尝试登录 mysql -u root

4. 配置

根据上一步安装mysql时，输出的提示，执行命令 mysql_secure_installation，接下去按提示一步一步来就可以了

5. 登录

mysql -u root -p密码

远程登录

用第三方客户端登录，可能会出现如下问题：Authentication plugin ‘caching_sha2_password‘ cannot be loaded

因为mysql8 之前的版本中加密规则是mysql_native_password,而在mysql8之后,加密规则是caching_sha2_password

处理办法：

1. 重新安装低版本的mysql brew install [email protected]
2. 修改加密规则

这里重点介绍第二种办法：

进入mysql

mysql -u root -p

查看用户的密码规则，以及对应的host

mysql> use mysql;
mysql> select user,host,plugin from user;
+------------------+-----------+-----------------------+
| user             | host      | plugin                |
+------------------+-----------+-----------------------+
| mysql.infoschema | localhost | caching_sha2_password |
| mysql.session    | localhost | caching_sha2_password |
| mysql.sys        | localhost | caching_sha2_password |
| root             | localhost | mysql_native_password |
+------------------+-----------+-----------------------+
4 rows in set (0.00 sec)

可以看到root用户的加密规则是：caching_sha2_password

修改加密规则以及密码

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '替换成你的密码';

检查一下是否修改成功

mysql> select user,host,plugin from user;

在尝试用第三方客户端连接
