VPS database connection 20, VPS database connection

The applications in different operating environments are used in the nature of the first class, and each has its own advantages and disadvantages.

Let's briefly introduce the environment of each database application, most of our small and medium-sized enterprises** servers use Windows Server operating procedures According to the use of the situation, we have to subdivide what type of database is used.

my-sql: suitable for medium and large ** establishment, it supports more diverse query statements, conditions, etc., and the storage space that can be supported is also very large, but this kind of database should be placed in the space or server that supports ms-sql database, which virtually increases the cost of building our website.

Access database: suitable for small and medium-sized ** sites, his advantages are fast site building speed, fast connection speed, because it can be placed in the same space as ** program, and the read speed will be faster, but compared with the ms-sql database, the storage space capacity is small, the query statements that can be supported are few, and the security factor is low, if the protection measures are not good enough, it is easy to be directly ** down, resulting in incalculable losses.

The above two are database programs produced by Microsoft, they all have a common advantage, friendly interface, most of the functions can be directly operated, relatively easy to master, and the support for Microsoft's web page production program is more perfect, such as etc.

MySQL database, most PHP or JS programs will use this database, suitable for small and medium-sized enterprises, its security factor is higher than the access database, and it also needs to have space or server to support this database program to run, but it occupies less space, fast website building, cross-platform support, and the perfect combination with PHP programs, and has also been appreciated by the majority of users and favored by technicians, but the shortcomings of MySQL are also obvious to all, The program control interface is similar to the MS-DOS system in the 90s of the last century, all of which are operated by writing **, and there is no place for interface operation at all, although there are desktop programs similar to managing this database, but due to the production of different companies, there are certain problems in combination.

So what is a database, the database is in accordance with the data structure to store our information, etc., a real sense of ** is impossible to lack the database, for example, we have a large number of information to add in**, so that it is impossible to make a static page, at this time we need our database to complete, and then output the content of the database by a fixed style, so that a dynamic page is generated.

Are you database-to-database, or database-to-database?

Hello, what kind of database do you use mysql? sql？Is the environment all set up?

I'll give you a simple example. In the case of SQL, your ** is an ASP page, then you need to add a statement to the web page that links to the database, specifying that the web page points to a database on the local computer. This one involves ** development.

SQL statements, connect objects, and so on are required. If your page is PHP, then you need to review and modify the configuration file. Anyway, that's it, connect to a specific database by a command or a statement, **on**.

If you have any questions, you can contact me.

If not, you're better off asking your provider.

Different program configuration files have different locations and names!

So you tell your provider the name of the program and he will tell you how to do it!

If it is a MySQL database, you need to install PHP and MySQL to establish a connection!

Then modify the configuration file of ** and you can access it!

VPS is a server virtualization technology that can virtualize a physical server into multiple logical servers to make full use of hardware resources.

VPS can set up a database just like using a stand-alone machine.

** is a big term that includes many technologies, the most important of which are web servers and databases. So, I understand you're asking how the web server is connected to the database, right? Personally, it is explained as follows:

1. The web server is the place where the web page is placed.

2. The database is the place where the data is placed.

3. Contact: The web page (there is a display**, there is a processing logic**) is written above, and the database is connected (this is of course the processing logic**), so as to obtain the data and then display it on the web page (here is the display**).

4. Let me explain what a server is: a server is a high-performance computer equipped with professional software. For example, a web server is a good computer with software such as IIS or Tomcat installed to host web pages, and the same is true for a database server.

5. Combined with your above question: VPS virtualizes a physical computer into multiple logical computers, and of course database software can be installed independently on each logical computer, such as SQL Server, Oracle, etc.

OK. Use it the same as a normal solo server.

VPS should be able to build a database, as long as VPS has an independent server function, you can install the program by yourself, and restart the server alone.
