nginx - Upgrading PHP to 5.5.9 -

there open-source project want install on server, grav, requires php 5.5.9. have php 5.4.16 installed on centos 7 server running on nginx. actually, php-fpm. question easiest , cleanest way achieve this? have read many articles online regarding , each 1 seems have different approach such uninstalling current version of php , reinstalling scratch. or suggestions accomplish task appreciated.

in order more modern version of php need use alternative repo. there few out there choose from, have traditionally packaged newer version of lamp stack components, remi, centos7 vagrant i'm using, went webtatic.

you should follow instructions setting alternative repo yum. involves:

rpm -uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm rpm -uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm 

once installed yum search php , you'll find php versions 5.5, 5.6, 7.0 , 7.1 choose from.

instead of yum install php you're going yum install php56w.

for example on vm, have php:

[vagrant@localhost:~]$ rpm -qa | grep php php56w-5.6.31-1.w7.x86_64 php56w-process-5.6.31-1.w7.x86_64 php56w-opcache-5.6.31-1.w7.x86_64 php56w-xml-5.6.31-1.w7.x86_64 php56w-pear-1.10.4-1.w7.noarch php56w-common-5.6.31-1.w7.x86_64 php56w-cli-5.6.31-1.w7.x86_64 php56w-mbstring-5.6.31-1.w7.x86_64 php56w-pdo-5.6.31-1.w7.x86_64 php56w-mysqlnd-5.6.31-1.w7.x86_64 php56w-fpm-5.6.31-1.w7.x86_64 php56w-gd-5.6.31-1.w7.x86_64 

you need uninstall current php version, involved operation, , want have done dry run, , confident know you're doing.

as confidence won't break, vagrant/virtualbox/docker etc., there no excuse not testing out in vm first.

not mention these foundation tech state of art development these days.

here's quick , simple vagrantfile vanilla centos7 box can have , running (assuming vagrant installed , working).
