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 < name.sql
恢复表：mysql -uroot -p dbname < name.sql (必须指定数据库)
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)
