How to compile and install PHP-FPM from source code

With the popularity and use of PHP, PHP-FPM is also known and used by more and more users and developers. Because PHP-FPM comes with more advanced process management and reloading tools, it is widely used in PHP programs in high-traffic and HTTP high-concurrency scenarios.

This article will explain how to compile and install PHP-FPM from source code, and explain it step by step. I believe that after reading the article, readers will easily and quickly install PHP-FPM for their systems to better adapt to various application scenarios.

1. Notes

Before installing PHP-FPM, you need to pay attention to the following:

1. Confirm the required system dependencies (including runtime and Dependencies during build);
2. Select the required PHP-FPM version, it is recommended to choose the latest version;

5. Install libjpeg and libjpeg-devel;
6. Install libpng and libpng-devel;
7. Install libmcrypt and libmcrypt-devel;
8 .Install zlib and zlib-devel;
9.Install libzip and libzip-devel.

Please follow the steps below to install the required dependencies:

1. Use yum to install GCC and make compiler:

sudo yum -y install gcc make

2. Install OpenSSL and OpenSSL-devel:

sudo yum -y install openssl openssl-devel

3. Install libxml2 and libxml2-devel:

sudo yum -y install libxml2 libxml2-devel

4. Install bzip2 and bzip2-devel:

sudo yum -y install bzip2 bzip2-devel

5. Install libjpeg and libjpeg- devel:

sudo yum -y install libjpeg libjpeg-devel

6. Install libpng and libpng-devel:

sudo yum -y install libpng libpng-devel

7. Install libmcrypt and libmcrypt-devel:

sudo yum -y install libmcrypt libmcrypt-devel

8. Install zlib and zlib-devel:

sudo yum -y install zlib zlib-devel

9. Install libzip and libzip-devel:

4. Install PHP-FPM

After confirming the installation environment and dependencies, you can start the installation of PHP-FPM.

1. Unzip the source code of PHP-FPM:

tar xzf php-7.4.12.tar.gz
cd php-7.4.12/

2 .Compile and configure:

./configure --prefix=/usr/local/php --with-fpm-user=www --with-fpm-group=www --with-gd -- enable-gd --with-jpeg --with-png --with-freetype --enable-bcmath --enable-fpm --enable-mbstring --enable-mysqlnd --with-zlib --with-zip -- with-mysqli --with-pdo-mysql --with-openssl

Please note that the above configure command will compile and configure PHP-FPM, and install library files, configuration files, etc. to /usr /local/php directory.

3. Install:

make && make install

4. Copy php.ini:

cp php.ini-production /usr/local /php/lib/php.ini

5. Modify the PHP-FPM configuration file:

cp /usr/local/php/etc/php-fpm.conf.default /usr/ local/php/etc/php-fpm.conf
vim /usr/local/php/etc/php-fpm.conf

Please modify php-fpm.conf according to the following configuration:

user = www
group = www
listen = 127.0.0.1:9000
listen.allowed_clients = 127.0.0.1
listen.backlog = -1
listen.owner = www
listen.group = www
listen.mode = 0666
pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 2
pm.max_spare_servers = 8
pm.process_idle_timeout = 10s
pm.max_requests = 2048

The above configuration is a basic PHP-FPM configuration example, you can modify it according to actual needs.

6. Start PHP-FPM:

/usr/local/php/sbin/php-fpm

5. Test

After the installation is completed, Check whether the /usr/local/php directory exists and whether php-fpm is running. You can use the following command to test whether PHP-FPM has been installed correctly:

/usr/local/php/bin/php - v
/usr/local/php/sbin/php-fpm -v

The above commands are used to view the PHP-FPM version and status respectively.

6. Summary

This article explains the installation and configuration process of PHP-FPM. I hope it will be helpful to the majority of PHP engineers and operation and maintenance engineers to avoid some configuration and installation aspects. The problem. I wish everyone can successfully install and use PHP-FPM and better adapt to various application scenarios!
