5用記事本開啟my-default.ini

修改

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

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

完成上述步驟之後，很多使用者開始使用MySQL，但會出現圖示的錯誤。這是因為沒有配置環境變數所致。

配置環境變數很簡單：

我的電腦->屬性->高階->環境變數

選擇PATH,在其後面新增: 你的mysql bin資料夾的路徑 (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,不是覆蓋)

以管理員身份執行cmd（一定要用管理員身份執行，不然許可權不夠），

輸入：cd C:\Program Files\MySQL\MySQL Server 5.6\bin 進入mysql的bin資料夾(不管有沒有配置過環境變數，也要進入bin資料夾，否則之後啟動服務仍然會報錯誤2)

輸入mysqld -install  (如果不用管理員身份執行，將會因為許可權不夠而出現錯誤：Install/Remove of the Service Denied!)

安裝成功

安裝成功後就要啟動服務了，繼續在cmd中輸入:net start mysql（如圖）,服務啟動成功！

mysqld -install  執行成功後就在系統的服務裡新增了如下服務：

在cmd輸入命令mysqladmin -uroot -p password （新密碼）

Enter password：（初始密碼沒有，所以直接回車）

密碼設定成功。

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.

Starting MySQL... SUCCESS!

修改密碼，執行/root/mysql_secure_installation：

[root@rhel6_lhr ~]# pwd

[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!
