本人在虛擬機(jī)上又安裝了一臺(tái)linux機(jī)器，作為MySQL數(shù)據(jù)庫服務(wù)器用，在安裝時(shí)選擇了系統(tǒng)自帶的MySQL服務(wù)器端，以下是啟用步驟。

首先開啟mysqld服務(wù)

#service mysqld start

進(jìn)入/usr/bin目錄
#cd /usr/bin

設(shè)定mysql數(shù)據(jù)庫root用戶的密碼
#mysqladmin -u root password '123456'

進(jìn)入mysql數(shù)據(jù)庫管理控制臺(tái)
#./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 root@192.168.0.100 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(jìn)行授權(quán)

然后重啟mysqld服務(wù)
#?service mysqld restart
Stopping MySQL:??????????????????????????????????????????? [? OK? ]
Starting MySQL:??????????????????????????????????????????? [? OK? ]

再次進(jìn)入mysql管理控制臺(tái)
#?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用戶的密碼

之后開啟防火墻的3306端口
#?vi /etc/sysconfig/iptables

以下是/etc/sysconfig/iptables的內(nèi)容，其中藍(lán)色一行是新加的。這一行可以由上一行復(fù)制得到，方法是在22哪行按下yy，然后按p，然后點(diǎn)insert鍵進(jìn)入編輯模式，修改22為3306，然后點(diǎn)esc，輸入wq保存退出。
# 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

防火墻重啟
#?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? ]

之后就可以在192.168.0.100上用mysqlfront連接數(shù)據(jù)庫了。
