How To Install Composr CMS on Ubuntu 18.04 LTS

Composr CMS is an open-source content management system for next-generation websites written in PHP with advanced social, interactive and dynamic functionality. The installation process is fairly easy and it takes only a couple of minutes.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation Joomla on an Ubuntu 18.04 (Bionic Beaver) server.

Install Composr CMS on Ubuntu 18.04 LTS Bionic Beaver

Step 1. First make sure that all your system packages are up-to-date

sudo apt-get update
sudo apt-get upgrade

Step 2. Install LAMP (Linux, Apache, MariaDB, PHP) server.

A Ubuntu 18.04 LAMP server is required. If you do not have LAMP installed, you can follow our guide here. Also install all required PHP modules:

apt-get install php7.1-cli php7.1-gd php7.1-opcache php7.1-mysql php7.1-json php7.1-mcrypt php7.1-xml php7.1-curl

Step 3. Installing Composr Cms on Ubuntu 18.04 LTS.

First, download the latest stable version of Composr Cms:

wget http://compo.sr/site/dload.php?id=457 -O composr.zip
mkdir /var/www/html/composr
unzip composr.zip -d /var/www/html/composr

We will need to change some folders permissions:

chown -R www-data:www-data /var/www/html/composr/
chmod -R 755 /var/www/html/composr/

Step 4. Configuring MariaDB for Composr Cms.

By default, MariaDB is not hardened. You can secure MariaDB using the mysql_secure_installation script. You should read and below each steps carefully which will set root password, remove anonymous users, disallow remote root login, and remove the test database and access to secure MariaDB.

mysql_secure_installation

Configure it like this:

- Set root password? [Y/n] y
- Remove anonymous users? [Y/n] y
- Disallow root login remotely? [Y/n] y
- Remove test database and access to it? [Y/n] y
- Reload privilege tables now? [Y/n] y

Next we will need to log in to the MariaDB console and create a database for the Composr Cms. Run the following command:

mysql -u root -p

This will prompt you for a password, so enter your MariaDB root password and hit Enter. Once you are logged in to your database server you need to create a database for Composr Cms installation:

MariaDB [(none)]> CREATE DATABASE composrdb;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON composrdb.* TO 'composr'@'localhost' IDENTIFIED BY 'your_password' WITH GRANT OPTION;
MariaDB [(none)]> SET @@global.sql_mode= '';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> quit

Step 5. Configuring Apache web server for Composr Cms.

Create a new virtual host directive in Apache. For example, create a new Apache configuration file named ‘composr.conf’ on your virtual server:

sudo a2enmod rewrite
sudo a2ensite composr.conf
touch /etc/apache2/sites-available/composr.conf
ln -s /etc/apache2/sites-available/composr.conf /etc/apache2/sites-enabled/composr.conf
nano /etc/apache2/sites-available/composr.conf

Add the following lines:

<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot /var/www/html/composr
ServerName your-domain.com
ServerAlias www.your-domain.com
<Directory /var/www/html/composr/>
Options FollowSymLinks
AllowOverride All
Order allow,deny
allow from all
</Directory>
ErrorLog /var/log/apache2/your-domain.com-error_log
CustomLog /var/log/apache2/your-domain.com-access_log common
</VirtualHost>

Now, we can restart Apache web server so that the changes take place:

systemctl restart apache2.service

Step 6. Accessing Composr CMS.

Composr CMS will be available on HTTP port 80 by default. Open your favorite browser and navigate to http://yourdomain.com/install.php or http://server-ip/install.php and complete the required the steps to finish the installation. If you are using a firewall, please open port 80 to enable access to the control panel.

How To Install Google Chrome on Ubuntu 18.04 LTS

Google Chrome is a freeware web browser developed by Google, uses the WebKit layout engine. It is available for the Linux, Android, iOS, Microsoft Windows, and Mac OS X operating systems. But Google Chrome is more than a web browser, as it combines sophisticated open source technology, borrowed from the Chromium application, into a minimal design, all in order to help users surf the web much faster, a lot easier, and safer than ever before.

This article assumes you have at least basic knowledge of linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo’ to the commands to get root privileges. I will show you through the step by step installation Google Chrome on a Ubuntu 18.04 LTS (Bionic Beaver) server.

Install Google Chrome on Ubuntu 18.04 Bionic Beaver

Method 1. Install Google Chrome on Ubuntu 18.04 LTS from the Command Line.

Step 1. First make sure that all your system packages are up-to-date

sudo apt-get update
sudo apt-get upgrade

Step 2. Installing Google Chrome on Ubuntu 18.04 LTS.

First, create a source list file for Google Chrome browser:

nano /etc/apt/sources.list.d/google-chrome.list

Next, copy the following APT line and paste it into google-chrome.list file:

deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main

After that, run the following command to download Google’s signing key:

wget https://dl.google.com/linux/linux_signing_key.pub
apt-key add linux_signing_key.pub

Now update package list and install the stable version of Google Chrome:

apt update
apt install google-chrome-stable

Step 3. Accessing Google Chrome.
Once installed, open Google Chrome from Ubuntu Dash or Terminal:

google-chrome-stable

If you wish to uninstall and remove Google Chrome from Ubuntu, run the following commands:

apt-get purge google-chrome-stable
apt-get autoremove

Method 2. Install Google Chrome on Ubuntu 18.04 the Graphical Way

Step 1. Go to https://www.google.com/chrome. Click the Download Chrome button.

Step 2. Then select the first option (64 bit .deb package), click Accept and Install.

Step 3. When Firefox asks you how to open this deb file, choose the default option to open it in Ubuntu Software (formerly Ubuntu Software Center).

If you choose the first option, Google Chrome deb package will be downloaded to /tmp/mozilla_$username directory. Once the download is complete, Ubuntu Software will automatically open. Click the Install button to install google-chrome-stable to Ubuntu 18.04. The version and installation size information can be seen in the Details section. 189.4MB of disk space! That’s huge for a Web browser.

Because software installation on Linux requires root privilege, so you have to enter your password to authenticate.

Step 4. Once the installation is complete, you can start Chrome browser in the Unity Dash or by typing the following command in the terminal.

google-chrome-stable
