After creating and starting an EC2 instance, install
nginx and the latest php.
This tutorial assumes you are using RedHat Enterprise, but it should apply to CentOS too.
Setup
Note: To facilitate getting stuff done, and to minimize permission
problems, disable selinux.
If you have utilized and configured used services
with selinux successfully before, then keep enabled and configure it appropriately.
Temporarily disable selinux
> # sudo
setenforce 0
Permanently disable selinux
> sudo vi
/etc/selinux/config
SELINUX=disabled
Update OS
> sudo yum
check-update
> sudo yum
update -y
If the kernel was updated, reboot
> sudo
reboot
Note: Included is some information if you try to use Amazon Linux 2 as the AMI,
but it does seem to have fewer packages, related to php anyway.
amazon-linux-extras is a mechanism in Amazon Linux 2 to enable the
consumption of new versions of application software on a stable operating
system that is supported until June 30, 2023. Extras help alleviate the
compromise between the stability of the OS and freshness of available software.
Enable Extra Packages for Enterprise Linux (EPEL) repo
Amazon Linux 2
> sudo
amazon-linux-extras install epel
RedHat Enterprise (version 8)
> sudo yum
install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
Also install remi repo to install php versions greater
than the RedHat php versions
> sudo yum
install http://rpms.remirepo.net/enterprise/remi-release-8.rpm
Install some extra utilities
> sudo yum
install htop iftop iotop
Install nginx
Amazon Linux 2
> sudo amazon-linux-extras enable nginx1
See which version of nginx is available
> sudo yum
info nginx
nginx 1.14.1
Install nginx
> sudo yum
install nginx
Test the default install
Amazon Linux 2
> sudo service
nginx start
RedHat Enterprise
> sudo
systemctl start nginx
View you EC2 instance via its default url (find in the
AWS EC2 Console)
http://ec2-1-2-3-4.us-east-9.compute.amazonaws.com
Enable nginx to run at boot
Amazon Linux 2
> sudo chkconfig
nginx on
RedHat Enterprise
> sudo
systemctl enable nginx
Additional actions for systemctl
> sudo
systemctl start nginx # start the server
> sudo
systemctl stop nginx # stop the server
> sudo
systemctl restart nginx # restart the
server
> sudo
systemctl reload nginx # reload the server
> sudo
systemctl status nginx # get status of the server
Install php
Amazon Linux 2
> sudo
amazon-linux-extras enable php7.3
Note: php-imap is not available in Amazon Linux 2 (as of 2020-01-10)
See versions of php avail
> sudo yum
module list php
Remi's Modular
repository for Enterprise Linux 8 - x86_64
Name Stream Profiles Summary
php remi-7.2 common [d], devel, minimal PHP scripting language
php remi-7.3 common [d], devel, minimal PHP scripting language
php remi-7.4 [e] common [d] [i], devel, minimal PHP scripting language
Red Hat
Enterprise Linux 8 for x86_64 - AppStream from RHUI (RPMs)
Name Stream Profiles Summary
php 7.2 [d] common [d], devel, minimal PHP scripting language
php 7.3 common [d], devel, minimal PHP scripting language
Enable and install php 7.4
> # sudo dnf
module reset php # resets back to RedHat
version
> sudo dnf
module install php:remi-7.4
Install some common packages
> sudo yum
install php-cli php-common php-fpm php-json php-mbstring php-xml \
php-pdo
php-mysqlnd php-gd php-gmp php-xmlrpc php-pecl-mcrypt php-pecl-zip php-imap
Start php-fpm
> sudo
systemctl start php-fpm
Enable php-fpm at boot
> sudo
systemctl enable php-fpm
> sudo
systemctl status php-fpm
Edit php-fpm to run with nginx user, replacing the httpd
or apache user
> sudo vi
/etc/php-fpm.d/www.conf
user = nginx
group = nginx
Restart the services
> sudo
systemctl restart php-fpm
> sudo
systemctl restart nginx
Note, if there are multiple apps per EC2, consider a
php-fpm pool per app ie replace www.conf with app1.conf, app2.conf etc
Create a test php page in the default web dir
> sudo vi
/usr/share/nginx/html/info.php
<?php
phpinfo();
You should be able to view the info page and php info
http://ec2-1-2-3-4.us-east-2.compute.amazonaws.com/info.php
But you will probably want to configure your application code user and
permissions, which will be a later post.
