深沉的船

Linux下安装MySQL5.0.37需要以下面三个包:
MySQL-client-community-5.0.37-0.rhel3.i386.rpm
MySQL-server-community-5.0.37-0.rhel3.i386.rpm
perl-DBI-1.53-2.fc7.i386.rpm
(以下步骤需要root权限)
1.验证是否已经安装过MySQL

rpm -qa|grep MySQL

rpm -qa|grep MySQL
如果发现有安装过,并需要卸载,使用下面命令

rpm -e MySQL-client-community MySQL-server-community

rpm -e MySQL-client-community MySQL-server-community
2.安装
执行:

rpm -ivh MySQL-client-community-5.0.37-0.rhel3.i386.rpm MySQL-server-community-5.0.37-0.rhel3.i386.rpm

rpm -ivh MySQL-client-community-5.0.37-0.rhel3.i386.rpm MySQL-server-community-5.0.37-0.rhel3.i386.rpm
如果控制台提示:

error: Failed dependencies:
perl(DBI) is needed by MySQL-client-community-5.0.37-0.rhel3.i386
perl(DBI) is needed by MySQL-server-community-5.0.37-0.rhel3.i386

error: Failed dependencies:<br/>perl(DBI) is needed by MySQL-client-community-5.0.37-0.rhel3.i386<br/>perl(DBI) is needed by MySQL-server-community-5.0.37-0.rhel3.i386
代表当前操作系统缺少DBI模块,请先安装DBI模块.

rpm -ivh perl-DBI-1.53-2.fc7.i386.rpm

rpm -ivh perl-DBI-1.53-2.fc7.i386.rpm
提示下面文字代表正确安装:
Preparing... ########################################### [100%]
1:perl-DBI ########################################### [100%]
重新执行MySQL的安装命令
提示下面文字代表正确安装:
Preparing... ########################################### [100%]
1:MySQL-server-community ########################################### [ 50%]
2:MySQL-client-community ########################################### [100%]
3.初始化安装
/usr/bin/mysql_install_db
4.启动mysql
/etc/init.d/mysql start
(停止有两种方法:[mysqladmin -uroot -p shutdown] [/etc/init.d/mysql stop])
5.验证安装成功
netstat -nat|grep 3306
如果能看到下面一行说明正常安装:
tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN
6.修改mysql的root用户密码

mysqladmin -u root password '123456'

mysqladmin -u root password '123456'
7.登陆mysql客户端

mysql -uroot -p

mysql -uroot -p
输入:123456
8.建立数据库

mysql> create database gbkdb character set gbk;
Query OK, 1 row affected (0.01 sec)

mysql> create database gbkdb character set gbk;<br/>Query OK, 1 row affected (0.01 sec)<br/>
9.为数据库gbkdb建立用户(用户:user 密码:123)

mysql> grant select,insert,update,delete,create on gbkdb.* to user@"%" identified by "123";
Query OK, 0 rows affected (0.01 sec)

mysql> grant select,insert,update,delete,create on gbkdb.* to user@"%" identified by "123";<br/>Query OK, 0 rows affected (0.01 sec)
10.修改配置

cp /usr/share/mysql/my-medium.cnf /etc/my.cnf

vi /etc/my.cnf

cp /usr/share/mysql/my-medium.cnf /etc/my.cnf<br/><br/>vi /etc/my.cnf<br/>
在[client]下面增加一行:
[client]
default-character-set = gbk
在[mysqld]下面增加三行:
[mysqld]
default-character-set = gbk
default-collation = gbk_chinese_ci
init_connect = 'SET NAMES gbk'
在[mysql]下面增加一行:
[mysql]
default-character-set = gbk
11.重启MySQL
/etc/init.d/mysql restart
12.重登陆mysql控制台确认配置变化

mysql -uroot -p

mysql -uroot -p<br/>
输入:123456

mysql> show variables like 'character_set_%';
-------------------------- ---------------------------- 
| Variable_name | Value |
-------------------------- ---------------------------- 
| character_set_client | gbk |
| character_set_connection | gbk |
| character_set_database | gbk |
| character_set_filesystem | binary |
| character_set_results | gbk |
| character_set_server | gbk |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
-------------------------- ---------------------------- 

mysql> show variables like 'character_set_%';<br/>-------------------------- ---------------------------- <br/>| Variable_name | Value |<br/>-------------------------- ---------------------------- <br/>| character_set_client | gbk |<br/>| character_set_connection | gbk |<br/>| character_set_database | gbk |<br/>| character_set_filesystem | binary |<br/>| character_set_results | gbk |<br/>| character_set_server | gbk |<br/>| character_set_system | utf8 |<br/>| character_sets_dir | /usr/share/mysql/charsets/ |<br/>-------------------------- ---------------------------- <br/>
13.在远程使用控制台登陆,确认用户可以使用

mysql -h10.10.1.156 -uuser -p

mysql -h10.10.1.156 -uuser -p<br/>
输入:123

mysql> use gbkdb;
Database changed 

mysql> use gbkdb;<br/>Database changed <br/>
