1. sudo apt-get install mysql-server, input administrator password , '123'

2. enter mysql promot in command line, 'mysql -u root -p', input password

3. create database "CREATE DATABASE xoops;"

4. 允许root远程登陆: 从所有主机:grant all privileges on *.* to root@"%" identified by "passw0rd" with grant option;

5. 建数据库,创建user:    

1) 建库:create database test1;   

 2) 建用户,赋权:grant all privileges on test1.* to user_test@"%" identified by "passw0rd" with grant option;   

 3) 删除数据库:drop database test1;    

6. 删除权限:    

1) revoke all privileges on test1.* from test1@"%";    

2) use mysql;    

3) delete from user where user="root" and host="%";    

4) flush privileges;    

8. 显示所有的数据库:show databases; 显示库中所有的表:show tables;

9. 远程登录mysql:mysql -h ip -u user -p

10. 备份和恢复    

备份单个数据库:mysqldump -uroot -p -B dbname > dbname.sql    

备份全部数据库:mysqldump -uroot -p --all-databases > all.sql    

备份表: mysqldump -uroot -p -B dbname --table tablename > tablename.sql    

恢复数据库:mysql -uroot -p

恢复表:mysql -uroot -p dbname

11. Sample:创建数据库表  mysql>CREATE DATABASE IF NOT EXISTS my_db default charset utf8 COLLATE utf8_general_ci;  

#注意后面这句话 "COLLATE utf8_general_ci",大致意思是在排序时根据utf8变码格式来排序  

#那么在这个数据库下创建的所有数据表的默认字符集都会是utf8了    

mysql>create table my_table (name varchar(20) not null default '')type=myisam default charset utf8;  #这句话就是创建一个表了,制定默认字符集为utf8

C++ sample code: 

1. boost libary is required.  "sudo apt-get install libboost-date-time-dev"

3. CREATE DATABASE FaceDB4. CREATE TABLE facetable (id INT,facename TEXT,username TEXT)
