A server is needed to build a website. In the process of purchasing a server, in addition to the common CPU, memory, hard disk, bandwidth and other configurations, users also need to choose the operating system by themselves. Most cloud servers use Windows Server or Linux operating systems:
Windows system
Windows Server is designed for servers Proprietary operating systems, including server applications developed by Microsoft, such as IIS Web server, tools used to support virtualization, and security tools including firewalls. The user interface and development environment of the Window System are object-oriented, easy to understand, learn and use. Windows is a single-user, multi-tasking operating environment that allows users to run multiple applications at the same time, or do several things in one program at the same time.
There are multiple versions of Windows: Win 2003 appeared earlier, but with the continuous improvement of the server hardware environment, Microsoft has basically stopped security updates to this version, so it is no longer listed. Into the recommendation. Now the more mainstream version is win2008, which is more mature than the former, both in terms of network optimization and system compatibility.
Win2012 expands the original functions of the system, and has the advantages of openness, scalability, security, high performance, and simple operation, but the application penetration rate needs to be improved.
Linux system
Linxu is an operating system built specifically for a multi-user server environment. It can enable different users to log in to the system together and share resources fairly. Linux runs stably and efficiently, and has a large number of users and community support. It can quickly find system vulnerabilities and quickly release security patches. In addition, it also supports a large number of high-quality open source software. However, Linux-based operating systems have higher technical requirements, and for small businesses or general users, there are certain management difficulties.
Linux has a large number of distributions available, each of which provides a complete server operating system and a manager, allowing users to easily install software such as web servers or email services, commonly used Distributions such as CentOS, Ubuntu and Debian. CentOS is an enterprise-level Linux distribution, which is stable, takes up less resources, and is simple to configure; Ubuntu has strong software source support and good compatibility, but mainly desktop applications; Debian is known for its stability, and the basic core of the entire system is very Small, for small memory, Debian is preferred.
How to choose the operating system
Then which operating system is more suitable in the process of building a website? Mainly depends on actual application requirements. Generally speaking, you can choose according to the development language of the website, the type of database and the user’s usage habits: if the development language is ASP, .NET, HTML, and the database is ACCESS, SQL Server, please choose Windows; if you develop The language is PHP, HTML, and the database is MySQL. Please choose the Linux system; in addition, if you need a large-scale development of the optional linux system, you are more accustomed to the optional windows system with a graphical interface.
Then what if the wrong system is selected? Don’t worry, you can apply to the service provider for replacement at any time.
Since reinstalling the system is equivalent to formatting the previous system disk, there is a risk of file loss. 56 Cloud Editor suggests that you can back up important data in advance, or choose to retain the data disk for reinstallation; however, when the user chooses The database version or operating system template is inconsistent with that before the reinstallation, and the service may not start. At this time, it is best to back up the server data to the local first, and choose to reinstall without keeping the data.
Except for the case of selecting the wrong system, when the system has been used for a long time, the running speed has slowed down, or the virus has suffered a sudden crash, it can also be solved by reinstalling the system.
