Discuss installation directory options to consider when compiling php7

In the process of developing and deploying PHP applications, we often need to compile the PHP environment from source code. Compiling the installation directory of PHP7 is one of the issues that needs attention.

In this article, we will discuss the installation directory options to consider when compiling PHP7 and provide some best practices.

Compile PHP7 installation directory

When compiling PHP7, you need to decide where PHP will be ultimately installed. When executing make install, the compiled binary files and other files will be copied to the specified installation directory.

Normally, there are three options:

1. /usr/local

/usr/local is UNIX Standard convention in systems for storing software programs installed by system administrators. The contents of this directory will not be deleted or overwritten during operating system upgrades. Therefore, this is one of the most popular installation directories.

./configure --prefix=/usr/local/php7

2. The /opt

/opt directory is another very popular installation directory. This directory can be used to store third-party software and provide better isolation between system software and third-party software. In addition, the name of the /opt directory is short and easy to remember.

./configure --prefix=/opt/php7

3. Home directory

The home directory is the home directory of each Linux user. Installing PHP7 into your home directory is not only convenient, but also reduces the need for administrator privileges. This is a very popular way for developers to build multiple applications with different PHP compilation options.

./configure --prefix=$HOME/php7

No matter which installation directory you choose, remember to make sure the ownership and permissions of the directory are set correctly so that you don't encounter problems when executing the make install command.

Best Practices

When choosing an installation directory, consider the following best practices:

1. Use a directory name that is easy to remember , such as /usr/local/php7 or /opt/php7. That way, if you need to install or upgrade PHP again in the future, you'll know where to find it.
2. Avoid installing to system directories, such as /usr or /bin. If a patch or upgrade to PHP requires modification of certain files in these directories, it may adversely affect the operating system. A better option is to use a separate directory.
3. Make sure the installation directory has the correct permissions. The operating system may not allow installation to certain directories, such as /root or /etc, and incorrectly set permissions may cause access issues.
4. Always install PHP into a non-root user's directory. On UNIX systems, for security reasons, the frequency of using the "root" user should be minimized.

Finally, it is recommended that you try different installation directories and check the behavior of PHP in each directory. This is a way to learn which directory best suits your needs.

Conclusion

During the compilation process of PHP7, it is important to correctly select the installation directory. Choosing the right directory helps manage PHP easily and reduces operating system impact. Use the best practices provided in this article to choose the correct installation directory and ensure that PHP is installed in the correct manner.
