Mariadb配置:
yum groupinstall mariadb mariadb-client
yum grouplist |grep maria
systemctl enable mariadb.service
systemctl restart mariadb.service
firewall-cmd --permanent --add-service=mysql
firewall-cmd --reload
firewall-cmd --permanent --list-all
mysql_secure_installation, 输入root密码,初始为空。
set root password->Remove anon user?yes->Disallow root login?yes->Remove test database?yes->Reload?yes
mysql -uroot -ptianyun; 创建数据库
show databases;
create database concats; show databases;
导入数据库:
mysql -uroot -ptianyun concats < /home/student/mariadb.dump
或者:
use concats; select database();
source /home/student/mariadb.dump;
show tables; 可以看到一张相应的表
授权用户访问, 可能要指定网段
help grant; 查看授权命令
grant select (limitation list) on concats.* to ‘luigi@‘%
flush privileges 刷新权限列表(系统关键字不分大小写,表名和库名分大小写)
mysql -uluigi -h 172.25.0.11 -ptianyun
use concats; select * from product;
单表查询:
desc product G 或 desc product; 查看表结构
select * from product where id_category=‘2‘
select count(*) from product where id...
select * from product where ... and ... 下划线_表示匹配一个字符,%表示多个
select * from product where name regexp ‘^T‘; 正则表达式
