Installing PHP5 and PHP7

Installing PHP5

Download the source Package
wget http://cn2.php.net/distributions/php-5.6.30.tar.gz

Unzip the source package
tar -zxvf php-5.6.30.tar.gz

To compile (enter the directory after PHP decompression)
./configure --prefix=/usr/local/php --with-apxs2=/usr/local/apache2.4/bin/apxs --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif

The following parameter meanings are:
--prefix Specifying the installation directory

--WITH-APXS2 is a tool for Apache automatic installation of expansion modules

--yith-config specify the path where the configuration file is located, PHP configuration file is called PHP.ini and MySQL is not the same

--with-mysql specifying the path to MySQL

The following pdo-mysql and Mysqli and MySQL are all MySQL drivers or specify its library, if you want to PHP and MySQL communication first to compile a module to support it,

Then there are some modules that are required to specify PHP.
--with-libxml-dir \
--WITH-GD \
--with-jpeg-dir \
--with-png-dir\
--with-freetype-dir\
--with-iconv-dir \
--with-zlib-dir \
--WITH-BZ2 \
--with-openss\
--with-mcrypt \
--ENABLE-SOAP \
--ENABLE-GD-NATIVE-TTF \
--enable-mbstring\
--enable-sockets\
--enable-exif\

Because our server is the first time to install PHP initialization process may encounter errors, is generally missing some libraries, the following error is missing XML2 related packages

Let's start with yum list |grep xml2 a look at the packages we need to install.

Here we need to install the Libxml2-devel package, yum installation (if you do not know which package to install a test, and then write down, this is the experience of judgment)
yum install -y libxml2-devel

After installation, then configure initialization.

The following error is missing OPENSSL-DEVL

yum inatall -y openssl-develInstalling the Openssl-devel Package

The following error is missing Bzip2-devel package

yum install -y bzip2-develInstalling the Bzip2-devel Package

The following error is missing Libjpeg-devel package

yum install -y libjpeg-develInstalling the Libjpeg-devel Package

The following error is missing Libpng-devel package

yum install -y libpng-develInstalling the Libpng-devel Package

The following error is missing Freetype-devel package

yum install -y freetype-develInstalling the Freetype-devel Package

The following error is missing Libmcrypt-devel package

If Epel is not installed, we need to install the Epel extension source first
yum install -y epel-release

yum install -y libmcrypt-develInstalling the Libmcrypt-devel Package

After installation, we will compile and install PHP

If you see the content, it proves that configure is a successful step.
Then make, finish and make install. or use it directly (make && make install)
make && make install

Then put the configuration file in the/usr/local/php/etc/directory renamed php.ini to complete the
cp php.ini-production /usr/local/php/etc/php.ini

Then we can take a look at its directory
ls /usr/local/php/

Where its core files are: Bin and bin/php

There are also the following files, he is a combination of Apache and PHP extension module
du -sh /usr/local/php/bin/php

View PHP-loaded modules (all static modules)
/usr/local/php/bin/php -m

View PHP Information
/usr/local/php/bin/php -i

PHP is an extension module that exists as a httpd and does not need to be started.

Installing PHP7

Download PHP7 's source package (enter SRC directory)
wget http://cn2.php.net/distributions/php-7.1.6.tar.bz2

Unzip the source package
tar jxvf php-7.1.6.tar.bz2

PHP7 and PHP5.6 installation is basically the same, the only difference is that the parameters behind the Configure initialization are slightly different

Enter the extracted source package to compile
./configure --prefix=/usr/local/php7 --with-apxs2=/usr/local/apache2.4/bin/apxs --with-config-file-path=/usr/local/php7/etc --with-pdo-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-bz2 --with-openssl --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-mbstring --enable-sockets --enable-exif

Nextmake && make install

Copy configuration file
cp php.ini-production /usr/local/php7/etc/php.ini

One machine installed PHP5 and PHP7 so which one to use?
You can edit the Apache configuration file to make a selection
vim /usr/local/apache2.4/conf/httpd.conf
