of is a super simple solution with multiple versions of php co existing under Linux systems

Since the release of php7, I, as the latest version control, immediately upgraded my experience, but due to the old programs running on the server, I had to deploy an php multi-version coexistence environment.

The existing environment is lnmp
- CentOS 6.7
- nginx 1.10.1
- mariadb-10.0.26
- php 7.0.8

5.4.45 is recommended for better compatibility with older php programs. mysql extensions are mainly compatible.

Start the installation

First download the ES22en-5.4.45.tar. gz source package.

Install through source code

# tar xzvf php-5.4.45.tar.gz
# cd php-5.4.45

# ./configure --prefix=/usr/local/php54 --with-config-file-path=/usr/local/php54/etc --enable-fpm --with-fpm-user=www --with-fpm-group=www --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd --with-iconv-dir --with-freetype-dir=/usr/local/freetype --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --enable-mbregex --enable-mbstring --with-mcrypt --enable-ftp --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --with-gettext --disable-fileinfo --enable-intl --with-xsl

# make ZEND_EXTRA_LIBS='-liconv'
# make install
# cp php.ini-production /usr/local/php/etc/php.ini

pm.min_spare_servers = 20
pm.max_spare_servers = 40
request_terminate_timeout = 100
request_slowlog_timeout = 0
slowlog = var/log/slow.log

Note: The focus is on configuring listening ports and processes

Start the php - fpm

# cp sapi/fpm/init.d.php-fpm /etc/init.d/php54-fpm
# chmod +x /etc/init.d/php54-fpm
# /etc/init.d/php54-fpm start

Modify the nginx configuration to use ES54en-5.4.45 for the required service configuration

location ~ [^/]\.php(/|$)
 {
  try_files $uri =404;
  fastcgi_pass unix:/tmp/php54-cgi.sock;
  fastcgi_index index.php;
  include fastcgi.conf;
 }

The php54-ES60en with ES58en-5.4.45 will start automatically when you start the machine

# chkconfig --add php54-fpm
# chkconfig php54-fpm on

chkconfig function description: Check and set up various services of the system.
Syntax: chkconfig [WM_ES67en][WM_ES68en][WM_ES69en][System Services]
chkconfig [� level < Level code > ][System Services][on/off/reset]

The focus of this program is

Each VERSION of PHP will be installed in a new, separate folder

The php-ES87en.conf configuration file for each version of PHP requires a different process name and listener port to be set

The nginx configuration file specifies the PHP version to be used to listen on the port or process name
