3.新建文件:my.ini
4.常用命令:
mysql Windows服务安装:mysqld install
执行:mysqld --initialize
mysql Windows服务自启动:
初次进入mysql免密登录:在my.ini文件中port=3306的下一行加上skip-grant-tables,然后重启mysql服务(改完了密码记得注释掉这句)
进入mysql:use mysql;
给root用户设置新密码mysql:update user set authentication_string=password("新密码") where user="root";
刷新数据库(尤其是改了root密码后一定要记得刷新):flush privileges;
退出:quit;
密码登录:mysql -hlocalhost -uroot -p
查看sql日志开启状态:showvariables like ‘%log_output%’;
开启sql日志:SET GLOBAL general_log = 'ON';
开启远程访问:grant all privileges on *.* to root@'%' identified by "password";
查看权限:select host,user,password from user;
查询表记录条数:
use information_schema;
select table_name, table_rows from tables where TABLE_SCHEMA = "epis" order by table_rows desc;
