设置root可以远程连接
update mysql.`user` set Host = ‘%‘ where User = ‘root‘ and Host = ‘localhost‘;
flush privileges; 或者重启服务 sudo service mysqld restart
关闭防火墙
sudo service firewalld stop
MySQL开启general_log跟踪数据执行过程
# 设置general log保存路径
# 注意在Linux中只能设置到 /tmp 或 /var 文件夹下,设置其他路径出错
# 需要root用户才有访问此文件的权限
mysql> set global general_log_file=‘/tmp/general.log‘;
# 开启general log模式
mysql> set global general_log=on;
# 关闭general log模式
mysql>set global general_log=off;
在general log模式开启过程中,所有对数据库的操作都将被记录 general.log 文件
新建用户
CREATE USER ‘imooc‘@‘%‘ IDENTIFIED BY ‘123456‘;
赋予权限
GRANT ALL PRIVILEGES ON *.* TO ‘imooc‘@‘%‘ IDENTIFIED BY ‘123456‘ WITH GRANT OPTION;
GRANT select,insert,update,delete ON *.* TO ‘imooc‘@‘%‘ IDENTIFIED BY ‘123456‘ WITH GRANT OPTION;
FLUSH PRIVILEGES;
收回权限
REVOKE ALL PRIVILEGES ON *.* FROM imooc;
FLUSH PRIVILEGES;
忘记root 密码
在 /etc/my.cnf 加入 skip-grant-tables
use mysql;
update user set authentication_string=password(‘456789‘) where user=‘root‘;
