Configure MPM CentOS Linux

Configure Multi-Processing modules contains two parts. First I override default Apache configuration for event mode that I picked during compilation. In that case you will know what is actually configured. So let’s start with that first.

At the bottom of httpd.conf you need to uncomment the line:

Include conf/extra/httpd-mpm.conf

It will enable advanced Apache httpd MPM configuration and it will override the defaults.

Now edit enabled file:

sudo vi /usr/local/apache2/conf/extra/httpd-mpm.conf

This file contains configuration of all MPM There are configuration for each MPM module, so make sure that you are setting correct values. I enabled event mode, so this is the section I care about:

<IfModule mpm_event_module>
StartServers 5
MinSpareThreads 75
MaxSpareThreads 250
ThreadsPerChild 25
MaxRequestWorkers 400
MaxConnectionsPerChild 0
</IfModule>

Install PHP From Source CentOS Linux

Install required tools for compilation

In order to compile PHP from source you need to install few tools and libraries. First you need EPEL repository to be enabled. This repository contains more recent version of packages.

sudo yum install epel-release -y

Once you have it installed execute following command to install required packages

yum install autoconf libtool re2c bison libxml2-devel bzip2-devel libcurl-devel libpng-devel libicu-devel gcc-c++ libmcrypt-devel libwebp-devel libjpeg-devel openssl-devel libxslt-devel -y

Download and unpack PHP Source code

Next step is downloading PHP source code. Easiest option is to download it from GitHub PHP releases. Choose the version you would like to install. In my case it’s 7.2.3. Copy link to tar.gz archive and execute following commands:

curl -O -L https://github.com/php/php-src/archive/php-7.1.18.tar.gz

tar -xvf php-7.1.18.tar.gz

cd php-src-php-7.1.18/

It will download the archive from GitHub, unpack the sources and change working directory to unpacked sources.

Compile PHP

Now it’s time to compile PHP. First we need to build configure command. In order to do that execute following command:

./buildconf --force

Once configure command is created we can use it to configure PHP installation. This process will enable certain PHP extensions such as PDO, FPM, OPCache, GD library etc. If you need any libraries that are not provided here, you can execute ./configure –help option and check if there is something you need. Following command will install PHP with most common extensions:

./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2/bin/apxs --with-freetype-dir=/usr/include/freetype2 --disable-short-tags --enable-xml --enable-cli --with-openssl --with-pcre-regex --with-pcre-jit --with-zlib --enable-bcmath --with-bz2 --with-curl --enable-exif --with-gd --enable-intl --with-mysqli --enable-pcntl --with-pdo-mysql --enable-soap --enable-sockets --with-xmlrpc --enable-zip --with-webp-dir --with-jpeg-dir --with-png-dir --enable-json --enable-hash --enable-mbstring --with-mcrypt --enable-libxml --with-libxml-dir --enable-ctype --enable-calendar --enable-dom --enable-fileinfo --with-mhash --with-incov --enable-opcache --enable-phar --enable-simplexml --with-xsl --with-pear

Apart from enabling extensions command above will also set where PHP will be installed. In my case it’s /usr/local/php location. If you will want to remove compiled PHP you will simply have to remove entire directory given under –prefix option.

Next it’s time to compile PHP. Please be aware that it takes few minutes:

make clean
make
make test

Install compiled PHP

Once PHP is compiled it is time to install it. Simply execute following command:

sudo make install

php.ini and OPCache configuration

Second thing is php.ini file. After installation php.ini file should located in /usr/local/php/lib. This is only the location. After compiling from source You won’t anything there so we need to copy it from uncompressed sources.

cd /usr/local/php/lib
cp /tmp/php-src-php-7.1.18/php.ini-development ./php.ini
vi php.ini

Add PHP to $PATH

We can do one more thing to make our life easier:) Add PHP executable to PATH, so we’ll be able to call php command from every directory.

echo 'pathmunge /usr/local/php/bin' > /etc/profile.d/php.sh

Execute such command, log out, log in and You’ll be able to execute:

php -v
