Shulou(Shulou.com)06/02 Report--

Since the advent of php7, as the latest version control, I immediately upgrade the experience, but because there are still old programs running on the server, I have to deploy a 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

For better compatibility with older php programs, 5.4.45 is recommended. It is mainly compatible with mysql extensions.

Start installation

The first step is to download the php-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-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

Php.ini configuration

Php-fpm.conf configuration

# vim / usr/local/php/etc/php- fpm.confu [global] pid = / usr/local/php54/var/run/php-fpm.piderror_log = / usr/local/php54/var/log/php-fpm.loglog_level = Notice [www] listen = / tmp/php54-cgi.socklisten.backlog =-1listen.allowed_clients = 127.0.0.1:9001listen.owner = wwwlisten.group = wwwlisten.mode = 0666user = wwwgroup = wwwpm = dynamicpm.max_children = 40pm.start_servers = 20pm.min_spare_servers = 20pm.max_spare_servers = 40request_terminate_timeout = 100request_slowlog_timeout = 0slowlog = var/log/slow.log

Note: the key point is to configure listening ports and processes

Start 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 php-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;}

Configure php54-fpm boot for php-5.4.45 to start automatically

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

Chkconfig function description: check and set up various services of the system.

Syntax: chkconfig [- add] [- del] [- list] [system Services]

Chkconfig [- level] [system Services] [on/off/reset]

The focus of this program is

Each version of PHP should be installed in a new separate folder

Each PHP version of the php-fpm.conf configuration file needs to set a different process name and listening port

The PHP version listening port or process name to be used is specified in the nginx configuration file
