选择虚拟主机应该注意什么问题？

网站建成之后，要购买一个虚拟主机才能发布网站内容，在选择虚拟主机和虚拟主机提供商时，作者建议，主要应考虑的因素包括：虚拟主机的网络空间大小、操作

系统、对一些特殊功能如数据库的支持，虚拟主机的稳定性和速度，虚拟主机服务商的专业水平等。下面是一些通常需要考虑的内容：
（1）虚拟主机服务商的专业水平和服务质量。这是选择虚拟主机的第一要素，如果选择了质量比较低下的虚拟主机服务商，很可能会在网站运营中遇到各种问题，

甚至经常出现网站无法正常访问的情况，或者遇到问题时很难得到及时的解决，这样都会严重影响网络营销工作的开展。
（2）虚拟主机的网络空间大小、操作系统、对一些特殊功能如数据库等是否支持。可根据网站程序所占用的空间，以及预计以后运营中所增加的空间来选择虚拟主

机的空间大小，应该留有足够的余量，以免影响网站正常运行。一般说来虚拟主机空间越大价格也相应较高，因此需在一定范围内权衡，也没有必要购买过大的空间

。虚拟主机可能有多种不同的配置，如操作系统和数据库配置等，需要根据自己网站的功能来进行选择，如果可能，最好在网站开发之前就先了解一下虚拟主机产品

的情况，以免在网站开发之后找不到合适的虚拟主机提供商。
（3）虚拟主机的稳定性和速度等。这些因素都影响网站的正常运作，需要有一定的了解，如果可能，在正式购买之前，先了解一下同一台服务器上其他网站的运行

情况。
（4）虚拟主机的价格。便宜无好货也是适合虚拟主机的，现在提供虚拟主机服务的服务商很多，质量和服务也千差万别，价格同样有很大差异，一般来说，服务器

和带宽租用是虚拟主机提供商最大的费用.由于一台主机能安排的虚拟主机数量在理论上并没有多大的限制,但实际上由于用户越来越多,肯定会影响网站的访问速度.

现在,虚拟主机市场的竞争非常激烈,部分虚拟主机提供商以低价参与竞争,牺牲的只能是主机的性能.
