这里数据库的安装是LAMP的一部分
用到的MySQL安装包
mysql-standard-5.0.16-linux-i686.tar.gz
1、安装以及初始化的部分
[root@localhost ~]# cd /usr/local/
[root@localhost local]# tar zxvf mysql-standard-5.0.16-linux-i686.tar.gz
[root@localhost local]# cd mysql-standard-5.0.16-linux-i686
[root@localhost mysql-standard-5.0.16-linux-i686]# cat INSTALL-BINARY （查看套件安装的介绍，下边列出的是必要的部分）
shell> groupadd mysql
shell> useradd -g mysql mysql
shell> cd /usr/local
shell> gunzip < /PATH/TO/MYSQL-VERSION-OS.tar.gz | tar xvf -
shell> ln -s FULL-PATH-TO-MYSQL-VERSION-OS mysql
shell> cd mysql
shell> scripts/mysql_install_db --user=mysql
shell> chown -R root .
shell> chown -R mysql data
shell> chgrp -R mysql .
shell> bin/mysqld_safe --user=mysql &
[root@localhost local]# ln -s mysql-standard-5.0.16-linux-i686 mysql
[root@localhost local]# cd mysql
[root@localhost mysql]# groupadd mysql
[root@localhost mysql]# useradd -g mysql mysql
[root@localhost mysql]# scripts/mysql_install_db --user=mysql
[root@localhost mysql]# chown -R root .
[root@localhost mysql]# chown -R mysql data
[root@localhost mysql]# chgrp -R mysql .
[root@localhost mysql]# bin/mysqld_safe --user=mysql &（开启服务）
2、数据库操作的部分（包括添加、删除数据库、数据表，以及相关的数据操作）
[root@localhost ~]# cd /usr/local/mysql/bin/
[root@localhost bin]# ./mysql
mysql> show databases;
mysql> create database bbs;
mysql> use bbs;
mysql> create table list(
-> id varchar(10) not null,
-> name varchar(10) not null,
-> password varchar(10) not null,
-> numbers int default 0)
-> engine=MyISAM;
mysql> describe list;
+----------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+----------+-------------+------+-----+---------+-------+
| id | varchar(10) | NO | | | |
| name | varchar(10) | NO | | | |
| password | varchar(10) | NO | | | |
| numbers | int(11) | YES | | 0 | |
+----------+-------------+------+-----+---------+-------+
4 rows in set (0.01 sec)
mysql> insert into list values ('001','sam','123456','20200');
Query OK, 1 row affected (0.00 sec)
mysql> insert into list values ('001','ken','123456','20300');
Query OK, 1 row affected (0.00 sec)
mysql> select * from list;
+-----+------+----------+---------+
| id | name | password | numbers |
+-----+------+----------+---------+
| 001 | sam | 123456 | 20200 |
| 001 | ken | 123456 | 20300 |
+-----+------+----------+---------+
2 rows in set (0.00 sec)
mysql> update list set numbers='3000000' where;
mysql> select * from list;
+-----+------+----------+---------+
| id | name | password | numbers |
+-----+------+----------+---------+
| 001 | sam | 123456 | 3000000 |
| 001 | ken | 123456 | 20300 |
+-----+------+----------+---------+
2 rows in set (0.00 sec)
mysql> delete from list where name like 'ken';
mysql> delete from list;
mysql> drop database bbs;
mysql> quit
结束
上述数据库的操作是在无密码的状况下，这里可以采用下边的操作给它加上密码
[root@localhost ~]# cd /usr/local/mysql/bin
[root@localhost bin]# ./mysqladmin -u root password '123456'
[root@localhost bin]# ./mysql -u root -p
Enter password:
