Piwigo an Open Source Photo Gallery2 min read

From their website, piwigi.org, Piwigo is an open source photo gallery software for the web which is designed for organizations, teams, and individuals. This article details the installation process for Piwigo on CentOS 7.

1. Install the LAMP Stack and Dependencies

The Linux, Apache, MySQL/MariaDB, and PHP stack is a basic stack which enables serving PHP based web applications. For CentOS, the database is MariaDB. For our installation, we want to install the latest version of PHP so we will install the epel repository, add the remi repository for CentOS 7, and disable any versions of PHP less than version 7.

# yum install epel-release
# yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
# ls -l /etc/yum.repos.d/
# vi /etc/yum.repos.d/remi-php54.repo (enabled=0)
# vi /etc/yum.repos.d/remi-php72.repo (enabled=1)

The following command will install everything necessary for Piwigo including the LAMP stack and other dependencies.

# yum install httpd mariadb mariadb-server php php-mysqli php-gd php-fpm php-devel php-pear gcc ImageMagick ImageMagick-devel unzip wget rsync pwgen curl

2. Enable Apache and MariaDB

After installing the dependencies, you need to start and enable Apache as well as MariaDB.

# systemctl start httpd mariadb
# systemctl enable httpd mariadb

3. Create Piwigo Database and Database User

Next, configure the root password for MariaDB and create the database and user for Piwigo. In the scripts below <password> is changed to the password of your choice.

# mysql_secure_installation
# mysql -u root -p
> CREATE DATABASE piwigo_db;
> CREATE USER 'piwigo_user'@'localhost' IDENTIFIED BY '<password>';
> GRANT ALL PRIVILEGES ON piwigo_db.* TO 'piwigo_user'@'localhost';

4. Install Piwigo

Now we can obtain the latest version of Piwigo using curl and then move it into the Apache web folder.

# curl http://piwigo.org/download/dlcounter.php?code=latest -o piwigo.zip
# unzip piwigo.zip
# mv piwigo /var/www/html
# chown apache. -R /var/www/html/

5. Make Changes for SELinux

You can handle SELinux in two ways. First you can simply just disable SELinix. A better way would be to have SELinux allow the files in our Piwigo directory.

# cd /var/www/html/piwigo/
# chcon -vR --type=httpd_sys_rw_content_t .

6. Completing the Web Installation

After all of this, you simply navigate to the root of your web installation (http://ip-address) and enter the credentials for your database and click Start installation.

7. Modify Time Zone

There are issues that may arise with the timezone if it is not set in the php.ini file. To correct any of these problems modify the date.timezone parameter in the file with the appropriate value.

# vi /etc/php.ini

In this article, I covered the basics of installing and configuring the open source image gallery Piwigo. The installation here covers an instance without SSL. In a future article, I will discuss the addition of SSL using reverse proxy and the changes that are necessary to keep Piwigo operating properly.
