MySQL is an open source relational database management system. It is one of the databases widely used by many developers and enterprises. Compiled installation of MySQL refers to installation through source code rather than using precompiled software packages.

Why do you need to compile and install MySQL? There are several important reasons.

1. Compilation and installation can provide higher performance. Precompiled software packages are usually designed to be compatible with multiple operating systems and hardware platforms, so they often contain some common settings and library files. Through compilation and installation, we can optimize the MySQL code according to our own needs, including selecting compilation options suitable for our own hardware platform, enabling performance optimization plug-ins, and making adjustments to our own applications. This can make full use of your own hardware resources and improve the running speed of MySQL.

2. Compile and install to customize the functions of MySQL. Precompiled software packages often contain some default settings and functions, which may not meet our needs. By compiling and installing, we can select the required modules and plug-ins to meet our own needs, and at the same time, we can turn off some unnecessary functions to reduce resource usage. This can make MySQL more lightweight, efficient and reliable.

3. Compiling and installing can also keep the latest version. Precompiled packages tend to have some lag as they need to go through the packaging, testing, and release process. By compiling and installing, we can get the latest MySQL code, including some of the latest fixes and features. This is important for developers and businesses who need access to the latest features and bug fixes.

4. Compilation and installation can also provide better security. Precompiled software packages may have some security risks during the packaging process, because many people are involved in this process, including packagers, testers, etc., and incomplete control and inspection processes may lead to some potential security issues. By compiling and installing, we can compile MySQL directly from the official source code to ensure its security and integrity.

Of course, there are also some disadvantages to compiling and installing MySQL. First of all, compilation and installation are relatively complicated and require a certain technical background and experience. Secondly, compiling and installing requires time and computing resources. Therefore, for some simple applications and small-scale systems, it may be more convenient and faster to use precompiled software packages.

To sum up, compiling and installing MySQL can provide higher performance, customized functions, keep the latest version and provide better security. But it takes some extra time and effort. Developers and enterprises should choose whether to use compilation and installation based on their own needs and actual conditions. No matter which method you choose, it is very important to maintain the security and stability of MySQL. Regular updates and upgrades are required, and loopholes and bugs are fixed in a timely manner to protect the integrity and availability of the database. .
