linux下安装mysql

本文提供了一步一步的指导来安装MySQL 5.1版本的服务器和客户端组件,并详细说明了如何设置root用户的密码,确保数据库的安全性。

1.从

 

http://mysql.saudi.net.sa/Downloads/MySQL-5.1/MySQL-server-community-5.1.57-1.rhel5.i386.rpm

下载mysql server
下载mysql client

2.运行
rpm -ivh MySQL-server-community-5.1.57-1.rhel5.i386.rpm

[root@localhost temp]# rpm -ivh MySQL-server-community-5.1.57-1.rhel5.i386.rpm
Preparing...                ########################################### [100%]
   1:MySQL-server-community ########################################### [100%]

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h localhost.localdomain password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

Please report any problems with the /usr/bin/mysqlbug script!

[root@localhost temp]# 
 3.启动mysql
service mysql start

4.安装mysql client
rpm -ivh MySQL-client-community-5.1.57-1.rhel5.i386.rpm
[root@localhost temp]# rpm -ivh MySQL-client-community-5.1.57-1.rhel5.i386.rpm
Preparing...                ########################################### [100%]
   1:MySQL-client-community ########################################### [100%]
[root@localhost temp]# 
 5.设置mysql密码
/usr/bin/mysql_secure_installation
提示输入原密码,默认是空,所以直接回车
为root用户设置密码,选择y并输入2次密码
删除匿名账号,选择y
是否禁止root用户远程登录,此项根据实际需要选择
是否删除test数据库,选择y
是否reload使设置立即生效,选择y
[root@localhost temp]# /usr/bin/mysql_secure_installation




NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!


In order to log into MySQL to secure it, we'll need the current
password for the root user.  If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): 
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

Set root password? [Y/n] Y
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] Y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] Y
 ... Success!

By default, MySQL comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] Y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] Y
 ... Success!

Cleaning up...



All done!  If you've completed all of the above steps, your MySQL
installation should now be secure.

Thanks for using MySQL!
