NGINX with PHP7

NGINX with PHP7

As the first step install whole packages for php7
#########################################################
apk add php7-fpm php7-mcrypt php7-soap php7-openssl php7-gmp php7-pdo_odbc php7-json php7-dom php7-pdo php7-zip php7-mysqli php7-sqlite3 php7-apcu php7-pdo_pgsql php7-bcmath php7-gd php7-odbc php7-pdo_mysql php7-pdo_sqlite php7-gettext php7-xmlreader php7-xmlrpc php7-bz2 php7-iconv php7-pdo_dblib php7-curl php7-ctype

Second:
Defining ENV variables which will be used in configuration. You can do this e.g. in /etc/profile.d/php7.sh
PHP_FPM_USER="www"
PHP_FPM_GROUP="www"
PHP_FPM_LISTEN_MODE="0660"
PHP_MEMORY_LIMIT="512M"
PHP_MAX_UPLOAD="50M"
PHP_MAX_FILE_UPLOAD="200"
PHP_MAX_POST="100M"
PHP_DISPLAY_ERRORS="On"
PHP_DISPLAY_STARTUP_ERRORS="On"
PHP_ERROR_REPORTING="E_COMPILE_ERROR\|E_RECOVERABLE_ERROR\|E_ERROR\|E_CORE_ERROR"
PHP_CGI_FIX_PATHINFO=0

after that source the system with it:

$ source /etc/profile.d/php7.sh

sed -i "s|;log_level\s*=\s*notice|log_level = notice|g" /etc/php7/php-fpm.d/www.conf #uncommenting line 

Fourth:
Modifying configuration file php.ini
##################################################################################
sed -i "s|display_errors\s*=\s*Off|display_errors = ${PHP_DISPLAY_ERRORS}|i" /etc/php7/php.ini
sed -i "s|display_startup_errors\s*=\s*Off|display_startup_errors = ${PHP_DISPLAY_STARTUP_ERRORS}|i" /etc/php7/php.ini
sed -i "s|error_reporting\s*=\s*E_ALL & ~E_DEPRECATED & ~E_STRICT|error_reporting = ${PHP_ERROR_REPORTING}|i" /etc/php7/php.ini
sed -i "s|;*memory_limit =.*|memory_limit = ${PHP_MEMORY_LIMIT}|i" /etc/php7/php.ini
sed -i "s|;*upload_max_filesize =.*|upload_max_filesize = ${PHP_MAX_UPLOAD}|i" /etc/php7/php.ini

sed -i "s|;*cgi.fix_pathinfo=.*|cgi.fix_pathinfo= ${PHP_CGI_FIX_PATHINFO}|i" /etc/php7/php.ini

Fifth:
To add PHP support to Nginx we should modify Nginx configuration file:
###################################################################################
vi /etc/nginx/nginx.conf

Sixth:
user                            www;
worker_processes                1;

error_log                       /var/log/nginx/error.log warn;
pid                             /var/run/nginx.pid;

events {
    worker_connections          1024;
}

http {
    include                     /etc/nginx/mime.types;
    default_type                application/octet-stream;
    sendfile                    on;
    access_log                  /var/log/nginx/access.log;
    keepalive_timeout           3000;
    server {
        listen                  80;
        root                    /www;
        index                   index.html index.htm index.php;
        server_name             localhost;
        client_max_body_size    32m;
        error_page              500 502 503 504  /50x.html;
        location = /50x.html {
              root              /var/lib/nginx/html;
        }
        location ~ \.php$ {
              fastcgi_pass      127.0.0.1:9000;
              fastcgi_index     index.php;
              include           fastcgi.conf;
        }
    }
}

##########################################################################
PD: In our configuration we have line: "fastcgi_pass 127.0.0.1:9000"
It should be corresponing to the line "listen = 127.0.0.1:9000" in PHP configuration file /etc/php7/php-fpm.d/www.conf

Seventh:
Set the timezome
########################################################################################
Timezone
For configuring Timezone you may use tzdata package which can be installed by running:

apk add tzdata

Timezone configuration

TIMEZONE="America/Guatemala"
cp /usr/share/zoneinfo/${TIMEZONE} /etc/localtime
echo "${TIMEZONE}" > /etc/timezone
sed -i "s|;*date.timezone =.*|date.timezone = ${TIMEZONE}|i" /etc/php7/php.ini


Eighth
Create a sample of the phpinfo() function
################################################################
vi /www/phpinfo.php

<?php
	phpinfo();
?>

Nineth
##########################################################################################################
###  Order the task to start, add to the runlevel default  and Test it !!!!
Starting Nginx with PHP7
#####################################################
Nginx should be restarted because we have changed it's configuration. Restart it by running:

rc-service nginx restart

After the installation PHP is not running. Start it by running:
#####################################################
rc-service php-fpm7 start

Runlevel
Normally you want to start the web server when the system is launching. This is done by adding Nginx and PHP to the needed runlevel.
#####################################################
rc-update add nginx default
rc-update add php-fpm7 default

Now they should start automatically when you boot your machine next time. To test that run:
#####################################################
reboot

To make sure that Nginx and PHP are started run command:
#####################################################
ps aux | grep 'nginx\|php-fpm'

You should get something like this:
#####################################################
  263 root       0:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
  264 www        0:00 nginx: worker process
  291 root       0:00 php-fpm: master process (/etc/php7/php-fpm.conf)
  302 www        0:00 php-fpm: pool www
  303 www        0:00 php-fpm: pool www
  310 root       0:00 grep nginx\|php-fpm

Testing Nginx with PHP
This section is assuming that nginx is running and sample html page "/www/phpinfo.php" is created. Launch a web browser and point it to
#####################################################
http://X.X.X.X/phpinfo.php
where X.X.X.X is IP address of your web server

Tenth
#####################################################
Troubleshooting
If PHP is not started check php-fpm log file
#####################################################
less /var/log/php-fpm.log

Make sure that configuration files do not contain errors
#####################################################
vi /etc/php7/php-fpm.conf
vi /etc/php7/php.ini



Resulto as follows
#####################################################

http://xxx.xxx.xxx.xxx/phpinfo.php
