为了阻止过多的失败phpMyAdmin登录尝试fail2ban，我创建了一个脚本来记录对文件的失败尝试：/var/log/phpmyadmin_auth.log
自定义日志
/var/log/phpmyadmin_auth.log文件格式为：
phpMyadmin login failed with username: root; ip: 192.168.1.50; url: http://somedomain.com/phpmyadmin/index.php
phpMyadmin login failed with username: ; ip: 192.168.1.50; url: http://192.168.1.48/phpmyadmin/index.php
自定义过滤器
[Definition]
# Count all bans in the logfile
failregex = phpMyadmin login failed with username: .*; ip: <HOST>;
phpMyAdmin 监狱
[phpmyadmin]
enabled = true
port = http,https
filter = phpmyadmin
action = sendmail-whois[name=HTTP]
logpath = /var/log/phpmyadmin_auth.log
maxretry = 6
该fail2ban日志包含：
2012-10-04 10:52:22,756 fail2ban.server : INFO Stopping all jails …我们目前有三个网络服务器。
服务器一和二表现良好，但我在第三个方面遇到了真正的问题。
wget，curl并且yum都无法建立连接 - 也就是说，它们在解析主机并尝试连接后都挂起。
示例（我尝试了许多不同的网址）：
# wget http://rpm.pbone.net/index.php3/stat/4/idpl/13941547/dir/centos_5/com/httpd-2.2.3-43.el5.centos.i386.rpm.html
