本人在虛擬機器上又安裝了一臺linux機器，作為MySQL資料庫伺服器用，在安裝時選擇了系統自帶的MySQL伺服器端，以下是啟用步驟。

首先開啟mysqld服務

#service mysqld start

進入/usr/bin目錄
#cd /usr/bin

設定mysql資料庫root使用者的密碼
#mysqladmin -u root password '123456'

進入mysql資料庫管理控制檯
#./mysql -u root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 4

Server version: 5.0.67 Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> grant all privileges on *.* to root@'%' identified by "root";
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> grant select,update,insert,delete on *.* to [email protected] identified by "root";
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> quit
Bye

上面的步驟是進行授權

然後重啟mysqld服務
# service mysqld restart
Stopping MySQL:                                            [  OK  ]
Starting MySQL:                                            [  OK  ]

再次進入mysql管理控制檯

# mysql -u root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2
Server version: 5.0.67 Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> use mysql
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> update user set password=password('12345678') where user='root';
Query OK, 5 rows affected (0.00 sec)
Rows matched: 5  Changed: 5  Warnings: 0

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> quit
Bye

以上步驟是修改root使用者的密碼

之後開啟防火牆的3306埠
# vi /etc/sysconfig/iptables

以下是/etc/sysconfig/iptables的內容，其中藍色一行是新加的。這一行可以由上一行復製得到，方法是在22哪行按下yy，然後按p，然後點insert鍵進入編輯模式，修改22為3306，然後點esc，輸入wq儲存退出。
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

防火牆重啟
# service iptables restart
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Unloading modules:                               [  OK  ]
iptables: Applying firewall rules:                         [  OK  ]

之後就可以在192.168.0.100上用mysqlfront連線資料庫了。
