yum install mysql
yum install mysql-server
yum install mysql-devel
service mysqld start
ps -ef | grep mysqld
root@host# cd /usr/bin
./mysqladmin -u root -p shutdown
Enter password: ******
mysqladmin -u root password "new_password";
[root@host]# mysql -u root -p
Enter password:*******
. 方法1:在 mysql 数据库中的 user 表添加新用户
root@host# mysql -u root -p
Enter password:*******
mysql> use mysql;
Database changed
mysql> INSERT INTO user
(host, user, password,
select_priv, insert_priv, update_priv)
VALUES (‘localhost‘, ‘guest‘,
PASSWORD(‘guest123‘), ‘Y‘, ‘Y‘, ‘Y‘);
Query OK, 1 row affected (0.20 sec)
mysql> FLUSH PRIVILEGES;
. 方法2:通过SQL的 GRANT 命令
mysql> GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,DROP
-> ON TUTORIALS.*
-> TO ‘zara‘@‘localhost‘
-> IDENTIFIED BY ‘zara123‘;
. show databases
. use 数据库名
. show tables
. show columns from 表名
. show index from 表名
. SHOW TABLE STATUS LIKE [FROM db_name] [LIKE ‘pattern‘] \G: 该命令将输出Mysql数据库管理系统的性能及统计信息。
. show grants;查看当前用户(自己)权限:
. show grants for dba@localhost; 查看其他 MySQL 用户权限:
. grant all on . to dba@localhost;赋权
. revoke all on . from dba@localhost;撤销权限
. grant select on testdb.* to dba@localhost with grant option; 如果想让授权的用户,也可以将这些权限 grant 给其他用户,需要选项 grant option
