mysql安装

1.1 Linux之下MySQL安装的三种方案的比较

具体内容参考这篇bloghttp://blog.itpub.net/8183550/viewspace-680749/

 

一.1  windows 下安装(mysql-5.6.21-win32)

一.1.1  mysql server 安装

 

1登录   http://dev.mysql.com/downloads/

wps10F7.tmp[4]wps1108.tmp[4] 

2进入如下页面:(该图为页面最底部)

wps1109.tmp[4]wps110A.tmp[4] 

 

 

3下载完成解压该文件mysql-5.6.21-win32.zip

wps6CA5.tmpwps6CB5.tmp 

4打开文件mysql-5.6.21-win32

wps6CB6.tmp

5用记事本打开my-default.ini

wps6CB7.tmpwps6CC8.tmp 

 

修改

basedir=C:\Program Files\MySQL\MySQL Server 5.6(mysql所在目录)

datadir=C:\Program Files\MySQL\MySQL Server 5.6\data (mysql所在目录\data)

 

wps6CC9.tmp wps6CD9.tmp

完成上述步骤之后,很多用户开始使用MySQL,但会出现图示的错误。这是因为没有配置环境变量所致。

配置环境变量很简单:

我的电脑->属性->高级->环境变量

选择PATH,在其后面添加: 你的mysql bin文件夹的路径 (如:C:\Program Files\MySQL\MySQL Server 5.6\bin )

PATH=.......;C:\Program Files\MySQL\MySQL Server 5.6\bin (注意是追加,不是覆盖)

wps6CDA.tmp 

以管理员身份运行cmd(一定要用管理员身份运行,不然权限不够),

输入:cd C:\Program Files\MySQL\MySQL Server 5.6\bin 进入mysql的bin文件夹(不管有没有配置过环境变量,也要进入bin文件夹,否则之后启动服务仍然会报错误2)

输入mysqld -install  (如果不用管理员身份运行,将会因为权限不够而出现错误:Install/Remove of the Service Denied!)

安装成功

wps6CDB.tmp 

 

安装成功后就要启动服务了,继续在cmd中输入:net start mysql(如图),服务启动成功!

wps6CDC.tmp 

mysqld -install  执行成功后就在系统的服务里添加了如下服务:

wps6CDD.tmp 

 

在cmd输入命令mysqladmin -uroot -p password (新密码)

Enter password:(初始密码没有,所以直接回车)

密码设置成功。

wps6CDE.tmp 

 

 

一.1.1  mysql-workbench-community-6.2.3-win32-noinstall

登录http://dev.mysql.com/downloads/ 

wpsDC51.tmpwpsDC62.tmp

 

 

进入如下页面:

 wps6CF1.tmp

 wps6CF2.tmp 解压mysql-workbench-community-6.2.3-win32-noinstall.zip

wps6D03.tmp

打开文件D:\Program files\MySQL\MySQL Workbench 6.2.4 CE (winx64)

wps6D05.tmp 

wps6D06.tmp 

wps6D16.tmp 

 

填写相应的条件就可以连接数据库了

 

 

安装成功2个条件:

 

:安装MySQL workbench需安装

1.microsoft visual c++ 2013

2.wps6D17.tmp

wps6D18.tmp 

 

MySQL Workbench Prerequisites:

To be able to install and run MySQL Workbench your System needs to have libraries listed below installed. The listed items are provided as links to the corresponding download pages where you can fetch the necessary files.

· Microsoft .NET Framework 4 Client Profile

· Visual C++ Redistributable for Visual Studio 2013

 

一.1  linux下安装--rpm安装

下载安装包后将安装包利用ftp软件上传到server端,如图:

wps6D19.tmp

A RANDOM PASSWORD HAS BEEN SET FOR THE MySQL root USER !

You will find that password in '/root/.mysql_secret'.

 

You must change that password on your first connect,

no other statement but 'SET PASSWORD' will be accepted.

See the manual for the semantics of the 'password expired' flag.

 

Also, the account for the anonymous user has been removed.

 

In addition, you can run:

 

  /usr/bin/mysql_secure_installation

 

which will also give you the option of removing the test database.

This is strongly recommended for production servers.

 

See the manual for more instructions.

 

Please report any problems at http://bugs.mysql.com/

New default config file was created as /usr/my.cnf and

will be used by default by the server when you start it.

You may edit this file to change server settings

一.1.1  启动服务

/etc/init.d/mysql start  或  service mysql start

 

[root@rhel6_lhr ~]# service mysql start

Starting MySQL... SUCCESS!

[root@rhel6_lhr ~]#

 

修改密码,执行/root/mysql_secure_installation

 

[root@rhel6_lhr ~]# pwd

/root

[root@rhel6_lhr ~]# 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.

 

You already have a root password set, so you can safely answer 'n'.

 

Change the 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] n

... skipping.

 

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^Hn

... skipping.

 

Reloading the privilege tables will ensure that all changes made so far

will take effect immediately.

 

Reload privilege tables now? [Y/n] y

... Success!

 

 

 

 

All done!  If you've completed all of the above steps, your MySQL

installation should now be secure.

 

Thanks for using MySQL!
