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. 允許root遠程登陸： 從所有主機：grant all privileges on *.* to root@"%" identified by "passw0rd" with grant option;
5. 建數據庫，創建user：
1) 建庫：create database test1;
2) 建用戶，賦權：grant all privileges on test1.* to user_test@"%" identified by "passw0rd" with grant option;
3） 刪除數據庫：drop database test1;
6. 刪除權限：
1) revoke all privileges on test1.* from test1@"%";
2) use mysql;
3) delete from user where user="root" and host="%";
4) flush privileges;
8. 顯示所有的數據庫：show databases; 顯示庫中所有的表：show tables;
9. 遠程登錄mysql：mysql -h ip -u user -p
10. 備份和恢復
備份單個數據庫：mysqldump -uroot -p -B dbname > dbname.sql
備份全部數據庫：mysqldump -uroot -p --all-databases > all.sql
備份表： mysqldump -uroot -p -B dbname --table tablename > tablename.sql
恢復數據庫：mysql -uroot -p < name.sql
恢復表：mysql -uroot -p dbname < name.sql (必須指定數據庫)
11. Sample:創建數據庫表 mysql>CREATE DATABASE IF NOT EXISTS my_db default charset utf8 COLLATE utf8_general_ci;
#注意後面這句話 "COLLATE utf8_general_ci",大致意思是在排序時根據utf8變碼格式來排序
#那麼在這個數據庫下創建的所有數據表的默認字符集都會是utf8了
mysql>create table my_table (name varchar(20) not null default '')type=myisam default charset utf8; #這句話就是創建一個表了,制定默認字符集為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)
