今天上午9:30点。客服反馈DNS服务器WEB平台无法正常使用了。
上去查看了一下。又是500错误。
从提示信息来看，是tomcat在调用数据库时出现问题导致。
分析估计是，程序在写的时候不严谨造成调用数据库一时多过所致。
这种情况出现过多次了。做为非程序员的我，虽知道问题大概在哪，却一时无法解决。为了更明确的跟踪到问题点及实现服务的自我修复。特别完成以下脚本。
目标：
1.出现500错误时，能自动识别，并自动修复（即自重启WEB服务）
2.记录故障时间。查看是否有规律。以便定位故障。
3.自查周期。每分钟检查一次WEB日志。查一分钟前日志，若有记录500错误，则重启服务。

WEBmin及virtualmin实在出色。
今天很成功的利用他们实现虚拟主机的开设。包括BIND，POSTFIX 域名绑定等等。
安装了ZEND支持。同时测试安装shopEX
顺利搞定。

About Virtualmin
Virtualmin is a uniquely powerful and flexible web server administration tool. It is unmatched in features and ease of use. Based on Webmin, it offers a wide array of productivity-enhancing tools for hosting providers, web developers, web designers, and end users.
Virtualmin is Mobile
Imagine enjoying dinner at your favorite restaurant (I'm picturing a great little Thai place in downtown Austin), surrounded by friends. You get a phone call from your CEO...the website has been down for an hour, where are you!? Ah, that's no fun at all.
We can help. With Virtualmin, you'll know about problems before your customers, because it'll send you an SMS message when problems arise. And, Virtualmin is fully accessible via any web-enabled mobile device, so you can actually fix things without leaving the table. Restart services, check logs, or create a new mailbox, all from a simple menu-based UI. All before the food gets cold.
Virtualmin is Comprehensive
Most folks are content to sell you a halfway solution. One that addresses a few aspects of your server, and leaves the rest wholly unanswered. We're not like that. We wrote Webmin. You may have heard of it. It's the world's most popular web-based system administration tool and has millions of users world-wide. We know how to manage your server. Not just a couple of bits and pieces of it. We manage network settings, firewalls, PostgreSQL and MySQL databases, users and groups, startup services, system logs, directory services, filesystems, quotas, software packages, name service and redundancy, mail, spam and anti-virus, and much more. You'll find new uses for our products every day.
Virtualmin is Polite
There's a right way and a wrong way to build system administration tools. The right way is hard. It requires writing parsers for every configuration file that the system administers. Parsers that understand comments and respect file order. The right way allows you to edit configuration files by hand, if you prefer. It also allows you to use other tools, if they work the right way. We've chosen the right way. Our competitors have not. We don't blame them...it's very tempting to take the easy path. Luckily for you, we've made doing things the right way easy.
Virtualmin is Easy
It's no secret that the right tools can provide a boost to productivity. Virtualmin provides tools to boost your productivity in ways that are unavailable anywhere else. Installing new applications, like blogs, wikis, content management systems, and more, is just a couple of clicks in Virtualmin. Managing databases, users, logs, and mail services are made nearly automatic, and we don't do it at the expense of flexibility.
Virtualmin is Flexible
Most management products want you to work their way, forcing you to learn all of the ins and outs of their particular design decisions. Virtualmin works for you, not the other way around. While we have selected a few sensible defaults that suit most users most of the time, it's easy to change just about everything in a Virtualmin system. Don't like Postfix? Switch to Sendmail or qmail. Don't like ProFTPd? Try vsftpd, instead. Don't like local users? Switch to LDAP. We're serious about respecting your decisions, and so we use the default package manager for software updates, whenever possible. We locate files in the places you expect them to be, no matter what Operating System you run.
今天发现了Virtualmin，一个基于Webmin的虚拟主机管理模块。在自己的虚拟机上安装了Virtualmin，发现他的功能十分强大。个人感觉不比商业化的虚拟主机管理工具如DirectAdmin差。
Virtualmin提供了完美的中文支持。在Red Hat Linux Enterprise 4的Webmin上很顺利地安装了Virtualmin和他的插件。
Virtualmin默认使用如下组件： Apache, BIND, Postfix ,MySQL ,ProFTPD
webmin是一个可运行于Linux/freebsd的web界面的主机管理系统，本身自带以及有人贡献了不少模块
而virtualmin则是它的一个虚拟主机管理模块

今天QQ上一朋友介绍给我Webmin
经查资料：
Webmin是目前功能最强大的基于Web的Unix系统管理工具。管理员通过浏览器访问Webmin的各种管理功能并完成相应的管理动作。目前Webmin支持绝大多数的Unix系统，这些系统除了各种版本的linux以为还包括：AIX、HPUX、Solaris、Unixware、Irix和FreeBSD等。
Webmin 让您能够在远程使用支持 HTTPS (SSL 上的 HTTP)协议的 Web 浏览器通过 Web 界面管理您的主机。这在保证了安全性的前提下提供了简单深入的远程管理。这使得 Webmin 对系统管理员非常理想，因为所有主流平台都有满足甚至超出上述需求的 Web 浏览器。而且，Webmin 有其自己的“Web 服务器”，因此不需要运行第三方软件(比如 Web服务器)。万事具备。Webmin 的模块化架构允许您在需要时编写您自己的配置模块。Webmin 的模块化架构允许您在需要时编写您自己的配置模块。除了在此介绍的模块之外，Webmin 还包括许多模块。尽管目前我们将主要关注网络服务，但是您会看到，几乎您系统的每一部分都能够通过 Webmin 来配置和管理。
操作：
安装操作非常简单。
下载包－》解包－》运行./setup.sh 脚本安装。 默认设置。并配置好用户名，密码。
操作进行WEBIN安装测试。顺利安装完毕。访问：https://IP:10000/进入配置界面。功能超级无敌强。谁用谁喜欢。还可在线升级。
在配置界面，可支持中文。
