Build PHP from source

Packages without -dev typically do not contain necessary header files.

If you are using Debian or Ubuntu you can use apt-get build-dep php5 to install a large number of optional build-dependencies in one go. If you are only aiming for a default build, many of them will not be necessary though.

Building PHP

The latest PHP is PHP 5.6.6 at the time of writing, and we have latest Debian 7.8 Wheezy. Let’s get the dependencies we need to build PHP from source:

Needed dependecies, for sure:

apt-get -y install \
    libdb-dev libxpm-dev libbz2-dev libc-client-dev \
    libcurl4-openssl-dev libevent-dev libfreetype6-dev libgmp3-dev \
    libicu-dev libjpeg-dev libpng-dev libpspell-dev libsasl2-dev \
    libsnmp-dev libxml2-dev libxslt-dev unixodbc-dev

Download and unzip sources:

cd /usr/local/src
wget http://php.net/get/php-5.6.6.tar.bz2/from/this/mirror -O php.tar.bz2
tar -xvf php.tar.bz2

cd php-5.6.6/

Configure and compile PHP

In order to enable FPM in your PHP build you must add --enable-fpm to your configure line.

I have chosen to install it in /usr/local/php566-fpm. We must use the prefix switch in order for your new PHP to be installed inside a single directory.

The exact ./configure is so huge that I decided to put it in separate file.

./configure ... lot of stuff ...

Now, we make and install it, this could take a while:

# build
make --jobs=4

We can always clean up everything that make did with make clean.

For a faster build, -j N replace N with the number of CPU cores you have available - grep "cpu cores" /proc/cpuinfo.

By default PHP will build binaries for the CLI and CGI SAPIs, which will be located at sapi/cli/php and sapi/cgi/php-cgi respectively. To check that everything went well, try running sapi/cli/php -v.

# install php
# apt-get install checkinstall
checkinstall -D --pkgname="php-5.6.6-custom" make install

Note the neat trick about using a checkinstall tool. Option -D commands to build a Debian package.

When asked, use a name php-5.6.6-custom, so later I can remove it with apt-get remove php-5.6.6-custom

Plesk: Install PHP 5.4 on Debian Squeeze CheckInstall

Adding a folder conf.d which PHP will search for additional ini-files.

mkdir -p /etc/php5/php566/fpm/conf.d

When this is complete, the PHP is installed in place, and we need to copy the default php.ini file to the install directory:

cp php.ini-production /etc/php5/php566/fpm/php.ini

I have added the following to an ini-file in php.d, to enable OPCache and adjust some configuration files:

tmp=$(cat /etc/timezone)
sed -i "s#;date.timezone =#date.timezone = $tmp#" /etc/php5/php566/fpm/php.ini

cat <<'EOF' > /etc/php5/php566/fpm/conf.d/10-opcache.ini
; configuration for Zend opCache
post_max_size = 32M
upload_max_filesize = 32M
zend_extension=/usr/local/php566/lib/php/20131226/opcache.so
opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=2001
opcache.revalidate_freq=5
opcache.fast_shutdown=1
opcache.enable_cli=0
opcache.enable=1
EOF

Adding the PHP to Plesk

This can be done for every SAPI type, EXCEPT for php-fpm.

plesk bin php_handler --add \
    -displayname "5.6.6" \
    -path /usr/local/php566/bin/php-cgi \
    -phpini /usr/local/php-5.6.6/etc/php.ini \
    -type fastcgi \
    -id "fastcgi-5.6.6"

But for php-fpm, I will just switch executable in service script /etc/init.d/php5-fpm. Only the line DAEMON=/usr/sbin/$NAME will be changed.

sed -i -re 's/^(DAEMON=\/usr\/sbin\/\$NAME)/# \1\'$'\nDAEMON=\/usr\/local\/php566\/sbin\/php-fpm/g' /etc/init.d/php5-fpm
service php5-fpm restart

Configure command

By default most extensions will be compiled statically, i.e. they will be part of the resulting binary.

Only the opcache extension is shared by default, i.e. it will generate an opcache.so shared object in the modules/ directory. You can compile other extensions into shared objects as well by writing --enable-NAME=shared or --with-NAME=shared, but not all extensions support this.

php-fpm and php-cgi are mutually exclusive, as the php-cgi binary is not created if PHP is compiled with --enable-fpm. If you want to use PHP as FastCGI module and with the FPM daemon you must compile PHP several times until you get all the binaries you need.

Problems when compiling PHP with fpm and cgi

In this multi-line command, I used this trick about comments.

Configure usage from help

./configure usage:

By default, make install will install all the files in /usr/local/bin, /usr/local/lib etc. You can specify an installation prefix other than /usr/local using --prefix, for instance --prefix=$HOME.

Enable-disable, with-without, yes-no. Explanation:

--disable-option-checking  ignore unrecognized --enable/--with options
--disable-FEATURE          do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG]     include FEATURE [ARG=yes]
--with-PACKAGE[=ARG]       use PACKAGE [ARG=yes]
--without-PACKAGE          do not use PACKAGE (same as --with-PACKAGE=no)
--with-libdir=NAME         Look for libraries in .../NAME rather than .../lib
