mysql8忘记密码

查询进程 ps -ef |grep mysql
杀死进程
- kill -9 $进程id$ 或 systemctl stop mysqld
跳过权限启动
/usr/local/mysql/bin/mysqld --skip-grant-tables --port=13306 --socket=/usr/local/mysql/socket/mysql13306.sock &
另起会话登录
- 执行 mysql -u root --port=13306 --socket=/usr/local/mysql/socket/mysql13306.sock
- 修改密码
bash 复制代码
```
mysql> FLUSH PRIVILEGES;
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'uz@2024#uz';
mysql> exit;
```
正常启动mysql
- 杀死之前的mysql进程 $参照步骤一步骤二$
- 重新启动 mysql systemctl start mysqld
使用更改后的root密码登录并创建用户
cd /usr/local/mysql/bin/
./mysql -u root --port=13306 --socket=/usr/local/mysql/socket/mysql13306.sock -p
bash 复制代码
```
mysql> CREATE USER 'mysql_uz'@'%' IDENTIFIED BY 'UZ@2024';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'mysql_uz'@'%';
mysql> exit;
```
