开放Fedora10自带的MySQL5.0.67的对外数据库服务
MySQL5.0.67是Fedora10安装时的可选项目。
测试的笔记本IP为192.168.0.100，作为安装Fedora10和MySQL5.0.67的服务器BlackMachine的IP地址为192.168.0.104.
以下是对MySQL的配置过程。
查看/etc/my.cnf文件
[[email protected] ~]# cd /etc/
[[email protected] etc]# vi my.cnf
my.cnf文件内容如下，可作为参照，不需要进行修改。
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Default to using old password format for compatibility with mysql 3.x
# clients (those using the mysqlclient10 compatibility package).
old_passwords=1
# To allow mysqld to connect to a MySQL Cluster management daemon, uncomment
# these lines and adjust the connectstring as needed.
#ndbcluster
#ndb-connectstring="nodeid=4;host=localhost:1186"
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
[ndbd]
# If you are running a MySQL Cluster storage daemon (ndbd) on this machine,
# adjust its connection to the management daemon here.
# Note: ndbd init script requires this to include nodeid!
connect-string="nodeid=2;host=localhost:1186"
[ndb_mgm]
# connection string for MySQL Cluster management tool
connect-string="host=localhost:1186"
设定Root的密码：
[[email protected] etc]# /usr/bin/mysqladmin -u root password '123456'
进入/usr/bin目录
[[email protected] etc]# cd /usr/bin
进入MySQL管理，进行授权
[[email protected] bin]# ./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 [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> 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
重启下mysqld服务是否正常
[[email protected] bin]# service mysqld restart
Stopping MySQL: [ OK ]
Starting MySQL: [ OK ]
很好，然后再次进入数据库管理界面，又一次设定root的密码。
[[email protected] bin]# 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
修改/etc/sysconfig/iptables文件，增加3306对外端口。
[[email protected] bin]# vi /etc/sysconfig/iptables
/etc/sysconfig/iptables的内容，其中粗体一行为新加的。
# 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
重启下防火墙
[[email protected] bin]# 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 ]
查看系统中已经启动的网络连接和对应的端口信息，3306应该在列
[[email protected] bin]# netstat -tlnpu
Active Internet connections (only servers)

[[email protected] bin]#
看到3306在列后，就可以通过192.168.0.100上的数据库客户端软件进行连接测试了
以上画面表征测试通过。
