EPrints 3.4 and PostgreSQL
EPrints has supported PostgreSQL since quite early in its development. However, MySQL is the default database engine, so few repositories actually use PostgreSQL. This page examines how to setup the latest version of EPrints 3.4 (currently 3.4.2) using PostgresSQL.
Installiing and Configuring PostgreSQL
This is based on installing on a CentOS 7 Linux operating system. Carry out the following steps as the root user. 1. Install the required packages using YUM:
yum install postgresql postgresql-server perl-DBD-Pg
2. Perform initial PostgreSQL setup
3. Edit /var/lib/pgsql/data/pg_hba.conf by changing the following two lines to allow password-less local access and access from localhost (i.e. when using --host localhost flag with psql):
local all all peer host all all 127.0.0.1/32 ident
to local all all trust host all all 127.0.0.1/32 trust You may wish to set authentication option to md5 rather than trust to restrict access for some users on your server but you will need to manual set a password for the postgres user.
4. Enable and start PostgreSQL on the operating system
systemctl enable postgresql systemctl start postgresql
