CentOS 6.2上使用YUM安裝MYSQL
因為XAMPP不支持64位，所以我還是自己安裝MYSQL。使用默認的yum。

[plain]
yes | yum install mysql
yes | yum install mysql-server
然後運行
[plain]
service mysqld start
會有如下非常重要的輸出：

Initializing MySQL database: Installing MySQL system tables...
OK
Filling help tables...
OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
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 xxxxxx 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.
You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl
Please report any problems with the /usr/bin/mysqlbug script!
[ OK ]
Starting mysqld: [ OK ]
可以看到這個命令會初始化MYSQL，並且安裝MYSQL的系統數據表。如果沒有這個過程，那麼強行通過 mysqld_safe start 命令去啟動的話是會失敗的。
