    How To Install OctoberCMS on an Ubuntu 18.04 Server

    Open source content management system

    OctoberCMS is a free, open-source, self-hosted CMS platform based on the Laravel PHP Framework. There are two ways you can install OctoberCMS, either using the Wizard installer or Command-line installation instructions. Before you proceed, you should check that your Ubuntu 18.04 server meets the prerequisites.

    This guide will show you through the steps to install and configure OctoberCMS on an Ubuntu 18.04 server using the wizard installer.

    Prerequisites
    To follow this guide, you will need a Ubuntu 18.04 server with a regular user having sudo privileges. You will need to replace red highlighted text throughout this tutorial to meet your environment needs.

    Installing Dependencies
    First, you need to install number of dependencies on your Ubuntu 18.04 server by executing the following command:

    sudo timedatectl set-timezone Asia/Karachi

    sudo apt -y install vim wget curl git socat unzip bash-completion

    sudo apt -y install php-cli php-fpm php-pdo php-common php-mysqlnd php-curl php-json php-zip php-gd php-xml php-mbstring

    Starting PHP Service
    Once you are finished installing dependencies, execute the following commands to start php service and enable it on boot.

    sudo systemctl start php7.2-fpm

    sudo systemctl enable php7.2-fpm

    Output
    Synchronizing state of php7.2-fpm.service with SysV service script with /lib/systemd/systemd-sysv-install.
    Executing: /lib/systemd/systemd-sysv-install enable php7.2-fpm

    Now edit the following two php files and set the timezone according to your location:

    sudo vi /etc/php/7.2/fpm/php.ini

    date.timezone = Asia/Karachi

    Save and close.

    sudo vi /etc/php/7.2/fpm/php.ini

    date.timezone = Asia/Karachi

    Save and close.

    Restart the PHP-FPM service:

    sudo systemctl restart php7.2-fpm


    Installing Database
    To meet octobercms database requirement, we need to install mariadb server using the following command:

    sudo apt -y install mariadb-server

    Once you are done with mariadb installation, execute the following commands to start its service and enable it on boot.

    sudo systemctl start mariadb

    sudo systemctl enable mariadb

    Securing Database
    We need to execute following command to make our database secure

    sudo mysql_secure_installation

    Output
    NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
          SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

    In order to log into MariaDB to secure it, we'll need the current
    password for the root user.  If you've just installed MariaDB, and
    you haven't set the root password yet, the password will be blank,
    so you should just press enter here.

    Enter current password for root (enter for none):
    OK, successfully used password, moving on...

    Setting the root password ensures that nobody can log into the MariaDB
    root user without the proper authorisation.

    You already have a root password set, so you can safely answer 'n'.

    Change the root password? [Y/n] n
     ... skipping.

    By default, a MariaDB installation has an anonymous user, allowing anyone
    to log into MariaDB without having to have a user account created for
    them.  This is intended only for testing, and to make the installation
    go a bit smoother.  You should remove them before moving into a
    production environment.

    Remove anonymous users? [Y/n] y
     ... Success!

    Normally, root should only be allowed to connect from 'localhost'.  This
    ensures that someone cannot guess at the root password from the network.

    Disallow root login remotely? [Y/n] y
     ... Success!

    By default, MariaDB comes with a database named 'test' that anyone can
    access.  This is also intended only for testing, and should be removed
    before moving into a production environment.

    Remove test database and access to it? [Y/n] y
     - Dropping test database...
     ... Success!
     - Removing privileges on test database...
     ... Success!

    Reloading the privilege tables will ensure that all changes made so far
    will take effect immediately.

    Reload privilege tables now? [Y/n] y
     ... Success!

    Cleaning up...

    All done!

    If you've completed all of the above steps, your MariaDB
    installation should now be secure.

    Thanks for using MariaDB!

    Creating Database
    At this point, we need to create a database to meet octobercms requirement using the following commands:

    sudo mysql -u root -p

    create database octobercms;

    grant all on octobercms.* to 'ocmsadmin'@'localhost' identified by 'yourpassword';

    flush privileges;

    quit;


    Creating SSL Certificate
    To make OctoberCMS web access safe and secure, we need to generate a self-signed ssl certificate using openssl:
     
    sudo mkdir -p /etc/sslcerts

    sudo openssl req -x509 -nodes -days 1825 -newkey rsa:2048 -keyout /etc/sslcerts/example.com.key -out /etc/sslcerts/example.com.crt

    Output
    Generating a RSA private key
    ..........................+++++
    ........................................+++++
    writing new private key to '/etc/sslcerts/example.com.key'
    -----
    You are about to be asked to enter information that will be incorporated
    into your certificate request.
    What you are about to enter is what is called a Distinguished Name or a DN.
    There are quite a few fields but you can leave some blank
    For some fields there will be a default value,
    If you enter '.', the field will be left blank.
    -----
    Country Name (2 letter code) [AU]:PK
    State or Province Name (full name) [Some-State]:Sindh
    Locality Name (eg, city) []:Karachi
    Organization Name (eg, company) [Internet Widgits Pty Ltd]:Example
    Organizational Unit Name (eg, section) []:Example
    Common Name (e.g. server FQDN or YOUR name) []:labserver.example.com
    Email Address []:support@example.com

    Installing Nginx
    To host October CMS and make its web services available to users, we need to install either Nginx or Apache:

    sudo apt -y install nginx-full

    When you are done with installation, execute following commands to start nginx service and enable it on boot.


    sudo systemctl start nginx

    sudo systemctl enable nginx


    Output
    Synchronizing state of nginx.service with SysV service script with /lib/systemd/systemd-sysv-install.
    Executing: /lib/systemd/systemd-sysv-install enable nginx


    Now create octobercms.conf file under /etc/nginx/conf.d directory and insert the following contents:

    sudo nano /etc/nginx/conf.d/octobercms.conf
    server {
        listen [::]:443 ssl;
        listen 443 ssl;
        listen [::]:80;
        listen 80;

        server_name example.com;

        index index.php index.html;
        root /var/www;

        ssl_certificate /etc/sslcerts/example.com.crt;
        ssl_certificate_key /etc/sslcerts/example.com.key;

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

        location ~ \.php$ {
            include fastcgi_params;
            fastcgi_pass unix:/run/php/php7.2-fpm.sock;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_read_timeout 120s;
        }

        rewrite ^themes/.*/(layouts|pages|partials)/.*.htm /index.php break;
        rewrite ^bootstrap/.* /index.php break;
        rewrite ^config/.* /index.php break;
        rewrite ^vendor/.* /index.php break;
        rewrite ^storage/cms/.* /index.php break;
        rewrite ^storage/logs/.* /index.php break;
        rewrite ^storage/framework/.* /index.php break;
        rewrite ^storage/temp/protected/.* /index.php break;
        rewrite ^storage/app/uploads/protected/.* /index.php break;
    }


    Save and close file

    Verify nginx configuration using the following command:

    sudo nginx -t

    Output
    nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
    nginx: configuration file /etc/nginx/nginx.conf test is successful


    If you see any error in the above output then go back to configuration file and fix the errors.


    When done, type the following command to reload nginx service to take changes into effect

    sudo systemctl reload nginx
     

    Cloning October CMS
    We need to clone octobercms on our local Ubuntu machine from github using the following command:

    sudo mkdir -p /var/www/octobercms

    sudo chown -R $USER:$USER /var/www/octobercms

    sudo chmod -R go+rwx /var/www/octobercms

    cd /var/www/octobercms

    sudo git clone https://github.com/octobercms/install.git
