Omeka Classic 2.4 CMS is a free and open source digital publishing platform and Content Management System (CMS) for sharing digital collections and creating media-rich online exhibits. Omeka Classic 2.4 CMS enables scholars, librarians, archivists, museum professionals and cultural enthusiasts to create complex narratives and share rich collections and content at low cost without sacrificing design and technical quality. Omeka accepts and stores all types of files, including images, video, audio, multi-page documents, PDFs, Power Point presentations; and can handle large archives of metadata and files (with over 1 million items) with the only limitations being the power of your server.
In this tutorial we are going to install Omeka Classic 2.4 CMS on a Debian 9 LAMP VPS using Apache web server, PHP 7.1, and a MariaDB database.
We will start by adding a new sudo
user.
First, log into your server as root
:
ssh root@YOUR_VULTR_IP_ADDRESS
The sudo
command isn't installed by default in the Vultr Debain 9 server instance, so we will first install sudo
:
apt-get -y install sudo
Now add a new user called user1
(or your preferred username):
adduser user1
When prompted, enter a secure and memorable password. You will also be prompted for your "Full Name" and some other details, but you can simply leave them blank by pressing Enter
.
Now check the /etc/sudoers
file to make sure that the sudoers
group is enabled:
visudo
Look for a section like this:
%sudo ALL=(ALL:ALL) ALL
This line tells us that users who are members of the sudo
group can use the sudo
command to gain root
privileges. It will be uncommented by default so you can simply exit the file.
Next we need to add user1
to the sudo
group:
usermod -aG sudo user1
We can verify the user1
group membership and check that the usermod
command worked with the groups
command:
groups user1
Now use the su
command to switch to the new sudo user user1
account:
su - user1
The command prompt will update to indicate that you are now logged into the user1
account. You can verify this with the whoami
command:
whoami
Now restart the sshd
service so that you can login via ssh
with the new non-root sudo user account you have just created:
sudo systemctl restart sshd
Exit the user1
account:
exit
Exit the root
account (which will disconnect your ssh
session):
exit
You can now ssh
into the server instance from your local host using the new non-root sudo user user1
account:
ssh user1@YOUR_VULTR_IP_ADDRESS
If you want to execute sudo without having to type a password every time, then open the /etc/sudoers
file again, using visudo
:
sudo visudo
Edit the section for the sudo
group so that it looks like this:
%sudo ALL=(ALL) NOPASSWD: ALL
Please note: Disabling the password requirement for the sudo user is not a recommended practice, but it is included here as it can make server configuration much more convenient and less frustrating, especially during longer systems administration sessions. If you are concerned about the security implications, you can always revert the configuration change to the original after you finish your administration tasks.
Whenever you want to log into the root
user account from within the sudo
user account, you can use one of the following commands:
sudo -i
sudo su -
You can exit the root
account and return back to your sudo
user account any time by simply typing the following:
exit
Before installing any packages on the Debian server instance, we will first update the system.
Make sure you are logged in to the server using a non-root sudo user and run the following commands:
sudo apt-get update
sudo apt-get -y upgrade
Install the Apache web server:
sudo apt-get -y install apache2
Then use the systemctl
command to start and enable Apache to execute automatically at boot time:
sudo systemctl enable apache2
sudo systemctl start apache2
Check your Apache default site configuration file to ensure that the DocumentRoot
directive points to the correct directory:
sudo vi /etc/apache2/sites-enabled/000-default.conf
The DocumentRoot
configuration option will look like this:
DocumentRoot "/var/www/html"
We now need to enable the mod_rewrite
Apache module, so ensure that your Apache default site configuration file is still open, and add the following Directory
Apache directives just before the closing </VirtualHost>
tag, so that the end of your configuration file looks like this:
<Directory /var/www/html/>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all
</Directory>
</VirtualHost>
The most important directive shown above is AllowOverride All
.
Now save and exit the file, and enable the mod_rewrite
Apache module:
sudo a2enmod rewrite
We will restart Apache at the end of this tutorial, but restarting Apache regularly during installation and configuration is certainly a good habit, so let's do it now:
sudo systemctl restart apache2
We can now install PHP 7.0 along with all of the necessary PHP modules required by Omeka Classic CMS:
sudo apt-get -y install php php-gd php-mbstring php-common php-mysql php-imagick php-xml libapache2-mod-php php-curl php-tidy php-zip
Debian 9 defaults to using MariaDB database server, which is an enhanced, fully open source, community developed, drop-in replacement for MySQL server.
Install MariaDB database server:
sudo apt-get -y install mariadb-server
Start and enable MariaDB server to execute automatically at boot time:
sudo systemctl enable mariadb
sudo systemctl start mariadb
Secure your MariaDB server installation:
sudo mysql_secure_installation
The root
password will be blank, so simply hit enter when prompted for the root
password.
When prompted to create a MariaDB/MySQL root
user, select "Y" (for yes) and then enter a secure root
password. Simply answer "Y" to all of the other yes/no questions as the default suggestions are the most secure options.
Log into the MariaDB shell as the MariaDB root
user by running the following command:
sudo mariadb -u root -p
To access the MariaDB command prompt, simply enter the MariaDB root
password when prompted.
Run the following queries to create a MariaDB database and database user for Omeka Classic CMS:
CREATE DATABASE omeka_db CHARACTER SET utf8 COLLATE utf8_general_ci;
CREATE USER 'omeka_user'@'localhost' IDENTIFIED BY 'UltraSecurePassword';
GRANT ALL PRIVILEGES ON omeka_db.* TO 'omeka_user'@'localhost';
FLUSH PRIVILEGES;
EXIT;
You can replace the database name omeka_db
and username omeka_user
with something more to your liking, if you prefer. Also, make sure that you replace "UltraSecurePassword" with an actually secure password.
Change your current working directory to the default web directory:
cd /var/www/html/
If you get an error message saying something like 'No such file or directory'
then try the following command:
cd /var/www/ ; sudo mkdir html ; cd html
Your current working directory will now be: /var/www/html/
. You can check this with the pwd
(print working directory) command:
pwd
Now use wget
to download the Omeka Classic CMS installation package:
sudo wget https://github.com/omeka/Omeka/releases/download/v2.5.1/omeka-2.5.1.zip
Please note: You should definitely check for the most recent version by visiting the Omeka Classic CMS download page.
List the current directory to check that you have successfully downloaded the file:
ls -la
Remove index.html
:
sudo rm index.html
Let's quickly install unzip
so we can unzip the file:
sudo apt-get -y install unzip
Now uncompress the zip archive:
sudo unzip omeka-2.5.1.zip
Move all of the installation files to the web root directory:
sudo mv omeka-2.5.1/* /var/www/html
Change ownership of the web files to avoid any permissions problems:
sudo chown -R www-data:www-data * ./
Restart Apache again:
sudo systemctl restart apache2
Now we're ready to move on to the final step.
Omeka Classic CMS requires ImageMagick to process images so let's make sure that it is installed:
sudo apt-get -y install imagemagick
To complete the Omeka Classic CMS installation, we first need to edit the Omeka Classic CMS database configuration file, so first make sure you are in the webroot and then open the db.ini
file:
sudo vi ./db.ini
Replace the XXXXXXX
values with your database configuration details, as follows:
[database]
host = "localhost"
username = "omeka_user"
password = "UltraSecurePassword"
dbname = "omeka_db"
prefix = "omeka_"
charset = "utf8"
;port = ""
Once you have added the appropriate configuration values you can save and exit the configuration file.
Now visit the IP address of your server instance in your browser, or if you've already configured your Vultr DNS settings (and given it enough time to propagate) you can simply visit your domain instead.
To access the Omeka Classic CMS installation page, enter your Vultr instance IP address into your browser address bar, followed by /install/
:
http://YOUR_VULTR_IP_ADDRESS/install/
On the Omeka Configure Your Site
page, enter the following Default Superuser Account
:
Username: <superuser username>
Password: <a secure password>
Email: <superuser email address>
Next, enter the following Site Settings
:
Administrator Email: <administrator email>
Site Title: <the title off the site>
You can leave the rest of the Site Settings
at their default values or you can edit them to suit your personal requirements.
When you are satisfied with the above site configuration details, click Install
to finalize the installation.
You will be redirected to a Success
page.
To access the admin section simply click on the Admin Dashboard
button and enter your username and password. If you aren't redirected to the admin login page, you can enter the admin address manually:
http://YOUR_VULTR_IP_ADDRESS/admin/
You are now ready to start adding your content and configuring your materials and collections. Make sure you check out the excellent Omeka Classic CMS documentation for more information about how to build and configure your site.
