Can make novice friends quickly start.
It may be that we use a smaller VPS system with less memory performance when running certain programs. Here we can focus on creating and increasing swap space for Linux Xen VPS hosts, which provide sufficient resources for the program to run. Swap is just like the virtual memory of our Windows system, which can be used for a short time when there is not enough physical memory to help run the program.
Here,
. There are a lot of solutions circulating on the network at this layer, but they are not suitable for VPs, And the setting difficulty may be increased several times or dozens of times.
3. Why not I collect IP addresses from logs?
There are two main considerations: first, most VPs users disable the log because the disk space is too small and it is difficult to clear logs frequently.
Second, if the IP addres
We know that the VPS server is a virtualization technology, build VPS server virtualization software and new cloud architecture solutions are many, they have advantages and disadvantages, therefore, different VPS Server service providers may use different virtualization technology to build VPS servers, Similarly, the c

First look at the VPS is what: plain English is that it is from a physical server divided into multiple ' virtual ' server, has its own independent public network IP, independent memory, independent CPU, independent operating system configuration, independent hard disk space, etc., can be convenient to restart the server alone, its own installation program, Like a smaller version of the physical server, use it to do multiple virtual hosting, Enterpris

I personally feel that this platform has poor autonomy, whether it is for customers or carriers. For customers, this platform is a virtual operating system and cannot be set on their own in many aspects. It is typical of Windows virtual memory management, which is not good. For sellers, the operation of this platform is inseparable from the support of swsoft. Of course, small-scale operators do not have enough technical strength to maintain the platform, but they must still be unable to do witho
Personally feel the platform is less autonomous, whether it is to the customer or to the operator. For customers this platform is a virtual operating system, many aspects are not autonomous settings, typically Windows virtual memory management, very bad. For businesses, this platform can not operate without swsoft support, of course, the smaller operators do not have enough technical strength to maintain, it is certainly inseparable from this price is not the "support" of the Philippines, but fo

We may not be very clear about the concept of VPS (virtual private server.
VPs Technology Introduction
Use the latest virtualization technology hyper-V to create multiple mutually isolated Virtual Private hosts ("virtual private server" or "VPs") on a physical server ").
These VPs
A vps host (or VPS) is a virtual server that uses virtual server software to create multiple isolated small servers on a physical server, each VPS has its own operating system, independent space, independent memory, and independent CPU resources. It can independently execute programs and system configurations, its oper
