Day 20:_Configure Nginx + PHP-FPM Using Unix Sock

[dpakmishra.1983]

Following was my task -

The Nautilus application development team is planning to launch a new PHP-based application, which they want to deploy on Nautilus infra in Stratos DC. The development team had a meeting with the production support team and they have shared some requirements regarding the infrastructure. Below are the requirements they shared:

a. Install nginx on app server 3 , configure it to use port 8095 and its document root should be /var/www/html.

b. Install php-fpm version 8.2 on app server 3, it must use the unix socket /var/run/php-fpm/default.sock (create the parent directories if don’t exist).

c. Configure php-fpm and nginx to work together.

d. Once configured correctly, you can test the website using curl http://stapp03:8095/index.php command from jump host.

Error i got after submitting was - " - either ‘php-fpm’ is not installed or installed version is not ‘8.2’ on App Server 3"

Kindly provide me the steps to install php version 8.2

Hi @dpakmishra.1983

Please refer to Install PHP 8.2 on Fedora, RHEL, CentOS, Alma, Rocky or other clone - Remi's RPM repository - Blog

Following steps i did to accomplish the task

Install Nginx

sudo yum install -y nginx
sudo systemctl enable nginx

Configure NGINX for the app

Edited /etc/nginx/nginx.conf:

sudo vi /etc/nginx/nginx.conf

 server {
        listen       8093;
        listen       [::]:8093;
        server_name  stapp03;
        root /var/www/html;
 index index.php index.html;

 location / {
 try_files $uri $uri/ =404;
 }

 location ~ \ .php$ {
 include fastcgi_params;
 fastcgi_pass unix:/var/run/php-fpm/default.sock;
 fastcgi_index index.php;
 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
 }
}

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

sudo systemctl restart nginx

Install PHP-FPM 8.1

 sudo dnf install epel-release -y
 sudo dnf install https://rpms.remirepo.net/enterprise/remi-release-9.rpm -y
 sudo dnf module list php
 sudo dnf module enable php:remi-8.1 -y
 sudo dnf install php-fpm php php-cli php-common php-mysqlnd php-gd php-xml php-mbstring php-pdo php-opcache -y
 sudo systemctl start php-fpm
 sudo systemctl enable php-fpm
 

php-v
sudo systemctl status php-fpm

Configure PHP-FPM

Edited /etc/php-fpm.d/www.conf:

sudo vi /etc/php-fpm.d/www.conf

listen = /var/run/php-fpm/default.sock
;listen.owner = nginx
;listen.group = nginx
;listen.mode = 0660

sudo mkdir -p /var/run/php-fpm
sudo chown -R nginx:nginx /var/run/php-fpm

sudo systemctl enable --now php-fpm

Testing
From the Jump Host, I ran:
Curl… command

Error : php-fpm is not congigured to use ‘/var/run/php-fpm/default.sock’ socket App Server 3

Kindly detect the error in the whole process.

Hi @dpakmishra.1983

It’s worked properly from my end, please try to set these configure below in /etc/php-fpm.d/www.conf.

listen.owner = nginx
listen.group = nginx

[dpakmishra.1983]

@raymond.baoly

nginx

Sir , things are still not working for me with the above configuration.

Inside /etc/php-fpm.d/www.conf, i am changing the following

listen = /var/run/php-fpm/default.sock (removing the default value “/run/php-fpm/www.sock”)
;listen.owner = nginx
;listen.group = nginx

Kindly help.

[LSO]

You have to uncomment the ;listen.user and ;listen.group by removing the ‘;’

This is what i did to accomplish the task:

Install Nginx

sudo yum install -y nginx
sudo systemctl enable nginx

Configure NGINX for the app

        listen       [::]:8091;
        server_name  stapp03;
        root /var/www/html;
 index index.php index.html;

 location / {
 try_files $uri $uri/ =404;
 }

 location ~\.php$ {
    include fastcgi_params;
    fastcgi_pass unix:/var/run/php-fpm/default.sock;

  error_page 500 502 503 504 /50x.html;

sudo systemctl restart nginx

Install PHP-FPM 8.3

 sudo dnf install epel-release -y
 sudo dnf install https://rpms.remirepo.net/enterprise/remi-release-9.rpm -y
 sudo dnf module list php
 sudo dnf module enable php:remi-8.3 -y
 sudo dnf install php-fpm php php-cli php-common php-mysqlnd php-gd php-xml php-mbstring php-pdo php-opcache -y
 sudo systemctl start php-fpm
 sudo systemctl enable php-fpm
 

php -v
sudo systemctl status php-fpm

Configure PHP-FPM

Edited /etc/php-fpm.d/www.conf:

sudo vi /etc/php-fpm.d/www.conf

user = nginx

group = nginx

listen = /var/run/php-fpm/default.sock

listen.owner = nginx

listen.group = nginx

listen.mode = 0660

Also, ensure the directory exists:

sudo mkdir -p /var/run/php-fpm

sudo chown -R nginx:nginx /var/run/php-fpm

sudo systemctl enable --now php-fpm

From the Jump Host, I ran:

Thank you for the help @LSO

[Fathhy]

Is that task ok for you?

[mahin101]

I have been able to pass this task following this forum page.
But how would I be able to do it alone?

Can anyone give me any directions about how one would solve this organically?
Specifically the configuration works…

• I, by myself, changed the socket path of www.conf file but did not know what else to do.
• changed the port and root document path in /etc/nginx/nginx.conf file but that’s it.

[rudi]

what can be the reason, can any one help ?

[dpakmishra.1983]

Check the port number .
Follow the following steps:

dpakGit/100_Days_of_DevOps/blob/main/100_Day_Tasks/Day_20:_Configure_Nginx _+_PHP-FPM_Using_Unix_Sock/Task.md

[rudi]

Yea, true that is why I confused. I was asked to configure port 8094, so I did

Anywhere else that I need to configure it ??

[rudi]

I was asked to use port 8094, is there any other configuration needed other than this one ?

/etc/php-fpm.d/www.conf

user = nginx

group = nginx

listen = /var/run/php-fpm/default.sock

listen.owner = nginx

listen.group = nginx

listen.mode = 0660



I missed something else ?? Socket also fine, ownership has given to nginx ... :thinking:

[dpakmishra.1983]

 location ~\.php$ {                 # Consider this line
    include fastcgi_params;
    fastcgi_pass unix:/var/run/php-fpm/default.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}

Check the first “line location …” it seems from your screenshot there is a space between the following symbols"~" . There should not be a space between this two symbols.
2nd check the server name in the following lines :

server {
        listen       8091 ;
        listen       [::]:8091;
        server_name  stapp03;  #   <----- This line
        root /var/www/html;
 index index.php index.html index.htm;

[rudi]

Thank you deepak, but there is something else. still im not able to manage it.
