虚拟主机技术使得在一台物理服务器上创建多个站点成为可能,虚拟主机的确降低了企业上网建站的费用,但凡事都有个限度。根据经验来看,当一台虚拟主机上的站点大约超过一定数量(200个)以后,服务器的性能将明显下降,如果其中某些站点还要提供数据库查询服务,则服务器性能下降更为剧烈,有些国际著名的大型虚拟主机提供商甚至将每台服务器上的用户数量强行限制在100个以内。更有一些服务商为了吸引客户,居然敢把一个几十元的虚拟主机标注成数百人同时在线,更有甚者能够说不限制任何资源。这样的承诺大家可想而知,一台物理服务器最多能支持的同时在线人数一般是2000-3000人同时并发,一台普通服务器的成本在1万元/年左右,仔细想想,服务商为了赚回成本,要放多少个这样的站点在服务器上运行,这样的服务器能用吗?

(1)docker有着比虚拟机更少的抽象层。由于docker不需要Hypervisor实现硬件资源虚拟化,运行在docker容器上的程序直接使用的都是实际物理机的硬件资源。因此在CPU、内存利用率上docker将会在效率上有优势,具体的效率对比在下几个小节里给出。在IO设备虚拟化上,docker的镜像管理有多种方案,比如利用Aufs文件系统或者Device Mapper实现docker的文件管理,各种实现方案的效率略有不同。

Bottom line, managed WordPress hosting is hassle free fast WordPress hosting with high-quality support from staff with lots of WordPress experience. While all this sounds amazing, the plans for managed WordPress hosting is usually on the higher end of the scale. For example a personal account with a popular managed WordPress hosting provider costs $29/month where you can only host 1 site (getting maximum of 25,000 visitors per month). The next level higher where you are allowed multiple domains will cost you $99/month. A person starting out a blog cannot afford this.

We also use Load Impact service to send virtual users (VU) to each website to see how the hosting server would handle increased requests from multiple connections at once. This helps us see how the individual WordPress hosting company would perform during peak traffic times.

负载量远比空间容量重要,虽然虚拟主机的应用是多个用户分享一台独立服务器,但用户有必要向服务商了解,到底要有多少用户与自己分享同一台服务器资源。因为只有服务商在各个用户之间对所占资源作出公平的分配后,才能确实保证多数用户的实际利益。如果共享的用户太多、服务器超负载运行的话,必然会降低服务器的稳定性,降低cpu的处理能力,程序运行困难,使用户在访问网站时找不到页面、无法链接到数据库,甚至无法访问等严重故障。

虚拟机实现资源隔离的方法是利用独立的OS,并利用Hypervisor虚拟化CPU、内存、IO设备等实现的。例如,为了虚拟CPU,Hypervisor会为每个虚拟的CPU创建一个数据结构,模拟CPU的全部寄存器的值,在适当的时候跟踪并修改这些值。需要指出的是在大多数情况下,虚拟机软件代码是直接跑在硬件上的,而不需要Hypervisor介入。只有在一些权限高的请求下,Guest OS需要运行内核态修改CPU的寄存器数据,Hypervisor会介入,修改并维护虚拟的CPU状态。

现在,您已解压了安装文件夹、创建了 MySQL 数据库和用户并自定义了 WordPress 配置文件,那么也就准备好将您的安装文件复制到 Web 服务器文档根目录,以便可以运行安装脚本完成安装。这些文件的位置取决于您是希望 WordPress 博客位于 Web 服务器的实际根目录 (例如,my.public.dns.amazonaws.com) 还是位于根目录下的某个子目录或文件夹 (例如,my.public.dns.amazonaws.com/blog) 中。

虚拟主机作为网络服务,最重要的就是系统的稳定性。稳定性左右着虚拟主机的在线率,直接关系到网站是否能够被访问的问题。虚拟主机性能的好坏又取决于服务器的配置及所使用操作系统、软件本身因素之外还一定程度下和机房所处的外界环境有关。带宽是速度的保证,服务器的速度,取决于带宽。而带宽指的是虚拟主机连接到每台服务器上的带宽,很多服务商在宣传时经常只宣传连接入机房的带宽值,却没有说明每台服务器的可用带宽。作为消费者应该格外小心。而作为影响服务器稳定的外在因素而言,机房的温度、湿度、人为管控也显得格外重要,这就与服务商机房的管理维护成本投入有关。大的服务商他的机房内的温度、湿度、人为管控极其严格,这就减少了服务器不稳定率。所以一般所谓的品牌主机的价格都是比较高的,这部分价格就是主机商用来维护机房的,所以也是情理之中。

HostGator is a popular web hosting company that hosts over 8 million domains. WPBeginner website is hosted on HostGator dedicated servers, and we have been using them since 2007 for our various websites.

二、是否拥有机房,是否拥有一个可靠稳定, 主机 安全高速的机房是衡量一个成功的虚拟主机提供商的又一重要标准。在互联网行业,往往出现这样的情况:一些公司本身没有机房甚至根本没有机房,但是他们却往往以低于市场价格很多的价格向用户承诺各种服务。可想而知,缺乏足够的硬件支持,技术实力,这些承诺往往最终只能成为不切实际的空中楼阁。所以可以肯定的是:那些连机房的地点都不愿告诉客户的公司一定是含有欺诈成分的虚拟主机提供商,广大的用户应对这样的情况保持高度的警惕。
