In this article, we are going to learn how to install Backdrop CMS on AlmaLinux 8. So, let’s get started.

Try this wiki on our VPS. Starting at just $5/month with 24x7 In-house customer support.

Pre-requisites

Once you're all set, we'll proceed with Backdrop CMS installation and configuration.

Create Database

Let us begin with creating a Database and a user. We will then grant the required privileges to the user so it can interact with the Database.

mysql -u root

CREATE DATABASE crowncloud;

CREATE USER 'crowncloud'@'localhost' IDENTIFIED BY 'YOUR-PASSWORD-HERE';

GRANT ALL PRIVILEGES ON crowncloud.* TO 'crowncloud'@'localhost';

FLUSH PRIVILEGES;

quit

The above commands will give complete access to the user crowncloud. Replace YOUR-PASSWORD-HERE with a safe and secure password.

Configuring Nginx Reverse Proxy

Let's configure nginx.conf with the following command:

nano /etc/nginx/nginx.conf

Replace the nginx.conf file with the below configuration.

# For more information on configuration, see:
#   * Official English Documentation: http://nginx.org/en/docs/
#   * Official Russian Documentation: http://nginx.org/ru/docs/

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}

http {
    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile            on;
    tcp_nopush          on;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;
}

Now, type in Ctrl+O and type Ctrl+X to save and exit the file.

Create a new Nginx configuration file dev.conf for the domain with the following command:

vi /etc/nginx/conf.d/dev.conf

Add the following codes:

Replace dev.domainhere.info with Your Domain Name and Change SSL Path according to your SSL Path.

And also replace the root path, /var/www/html/backdrop with the actual path where your website's data are stored.

server {
listen 80;

server_name dev.domainhere.info;
root /var/www/html/backdrop;
index index.php index.html index.htm;

location / {
try_files $uri $uri/ /index.php?$args;
}

location = /favicon.ico {
log_not_found off;
access_log off;
}

location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
expires max;
log_not_found off;
}

location = /robots.txt {
allow all;
log_not_found off;
access_log off;
}

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

listen 443 http2 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/dev.domainhere.info/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/dev.domainhere.info/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}

Now, press the Esc key, and type in :wq! and press the Enter key to save and exit the file.

For SELinux enabled systems, Run the below command

setsebool -P httpd_can_network_connect 1

Now, restart & check the Nginx with the following commands:

systemctl restart nginx

systemctl status nginx

Enable http and https ( 80/443 )

To enable http and https connection through the firewall, follow the commands:
