Instalacja Nginx + PHP 7.2 na CentOS 7 / RHEL 7

PHP to akronim od słów PHP: Hypertext Preprocessor, jest mechanizmem działającym po stronie serwera. W PHP można tworzyć strony internetowe generowane dynamicznie lub osadzać skrypty PHP bezpośrednio w kodzie HTML. PHP można zintegrować z komercyjnymi i nie komercyjnymi systemami zarządzania bazami danych. Domyślnie CentOS 7/RHEL 7 dostarcza PHP tylko w wersji 5.4. Artykuł wyjaśnia jak zainstalować PHP 7.2 w systemach CentOS 7 l RHEL 7.

Instalacja PHP w wersji 7.2

Włączamy repozytorium EPEL:

$ sudo yum -y install epel-release

1	$ sudo yum -y install epel-release

Włączamy repozytorium Remi remi-php72:

$ sudo yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

$ sudo yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm

$ sudo yum install yum-utils

$ sudo subscription-manager repos --enable=rhel-7-server-optional-rpms

$ sudo yum-config-manager --enable remi-php72

$ sudo yum update

$ sudo yum search php72 | more

$ sudo yum install php72 php72-php-fpm php72-php-gd php72-php-json php72-php-mbstring php72-php-mysqlnd php72-php-xml php72-php-xmlrpc php72-php-opcache

Sprawdzenie wersji PHP:

$ php --version

1	$ php --version

Wylistowanie zainstalowanych modułów:

$ php72 --modules

1	$ php72 --modules

Włączenie usługi PHP fpm dla NGINX

Włączamy autostart php72-php-fpm :

$ sudo systemctl enable php72-php-fpm.service

1	$ sudo systemctl enable php72-php-fpm.service

Włączamy usługę php72-php-fpm :

$ sudo systemctl start php72-php-fpm.service

1	$ sudo systemctl start php72-php-fpm.service

Instalacja NGINX:

$ sudo yum -y install nginx

1	$ sudo yum -y install nginx

$ egrep '^(user|group)' /etc/nginx/nginx.conf
user nginx;

1 2	$ egrep '^(user\|group)' /etc/nginx/nginx.conf user nginx;

Edycja pliku /etc/opt/remi/php72/php-fpm.d/www.conf:

$ sudo vim /etc/opt/remi/php72/php-fpm.d/www.conf

1	$ sudo vim /etc/opt/remi/php72/php-fpm.d/www.conf

Ustawienie użytkownika i grupy na nginx:
user = nginx
group = nginx

Restart usługi php-fpm:

$ sudo systemctl restart php72-php-fpm.service

1	$ sudo systemctl restart php72-php-fpm.service

Edycja konfigu NGINX:

$ sudo vim /etc/nginx/nginx.conf

1	$ sudo vim /etc/nginx/nginx.conf

Po linii:

include /etc/nginx/conf.d/*.conf;

1	include /etc/nginx/conf.d/*.conf;

dodajemy:

include /etc/nginx/sites-enabled/*;

1	include /etc/nginx/sites-enabled/*;

Komentujemy lub usuwamy linie:

# server {
# listen 80 default_server;
# listen [::]:80 default_server;
# server_name _;
# root /usr/share/nginx/html;
#
# # Load configuration files for the default server block.
# include /etc/nginx/default.d/*.conf;
#
# location / {
# }
#
# error_page 404 /404.html;
# location = /40x.html {
# }
#
# error_page 500 502 503 504 /50x.html;
# location = /50x.html {
# }
# }

# server {

# listen 80 default_server;

# listen [::]:80 default_server;

# server_name _;

# root /usr/share/nginx/html;

# # Load configuration files for the default server block.

# include /etc/nginx/default.d/*.conf;

# location / {

# }

# error_page 404 /404.html;

# location = /40x.html {

# }

# error_page 500 502 503 504 /50x.html;

# location = /50x.html {

# }

Zakładamy katalog na logi wirtualnego serwera domain.com:

$ sudo mkdir /var/log/nginx/domain.com/

1	$ sudo mkdir /var/log/nginx/domain.com/

W katalogu /etc/nginx zakładamy katalogi sites-available i sites-enabled:

$ sudo mkdir /etc/nginx/sites-available
$ sudo mkdir /etc/nginx/sites-enabled

1 2	$ sudo mkdir /etc/nginx/sites-available $ sudo mkdir /etc/nginx/sites-enabled

Przykład konfigu /etc/nginx/sites-available/domain.com.vhost serwera wirtualnego:

server {
listen *:80;
server_name domain.com www.domain.com name.domain.com;

root /home/domain.com/public_html;
index index.html index.htm index.php index.cgi index.pl index.xhtml;

error_log /var/log/nginx/domain.com/error.log;
access_log /var/log/nginx/domain.com/access.log combined;

# in root location
location / {
# look for index.php/index.html/index.htm as "index file"
index index.php index.html index.htm;

# this is specifically for wordpress
# makes it possible to have url rewrites
try_files $uri $uri/ /index.php?$args;
}

# default error pages
# note that wp already catches most
error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {

}
# here we have to let nginx know what to do with these php files
# as html files are just send directly to the client
location ~ \.php$ {

try_files $uri =404;

# pass to the php-fpm server
fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

Po dodaniu pliku konfiguracyjnego dodajemy link symboliczny do konfigu serwera wirtualnego domain.com:

$ sudo ln -s /etc/nginx/sites-available/domain.com.vhost /etc/nginx/sites-enabled/domain.com.vhost

1	$ sudo ln -s /etc/nginx/sites-available/domain.com.vhost /etc/nginx/sites-enabled/domain.com.vhost

Dodajmy jeszcze domyślny serwer wirtualny /etc/nginx/sites-available/default.vhost:

# Default server configuration
#
server {
listen 80 default_server;
listen [::]:80 default_server;


root /var/www/html;

# Add index.php to the list if you are using PHP
index index.html index.htm index.nginx-debian.html;

server_name _;

# in root location
location / {
# look for index.php/index.html/index.htm as "index file"
index index.php index.html index.htm;
# this is specifically for wordpress
# makes it possible to have url rewrites
try_files $uri $uri/ /index.php?$args;
}

# default error pages

error_page 404 /404.html;
error_page 500 502 503 504 /50x.html;
location = /50x.html {
