I ran command to install driver: yum install php7.4-pgsql pgAdmin will fail to connect to the database if ident is set because for local connection PostgreSQL will obtain the operating system user name from the operating system and check if it matches the requested database user name.I get the error from PDO when trying to connect to PostgreSQL: Database Connection Error: could not find driver In pg_hba.conf you should find by default “IPv4 local connections” method set to ident. If the file is not in this folder the following command should allow you to find it: Sudo nano /var/lib/pgsql/10/data/pg_hba.conf To be able to connect pgAdmin to PostgreSQL we must modify the PostgreSQL host-based authentication ( HBA) configuration because by default, PostgreSQL does not allow password authentication. That should do the trick, now let’s connect pgAdmin to PostgreSQL 10 Install pgadmin4 desktop version (there is also a server version if you want) You are now connected as postgres, now you need to enter psql to enter the postgres shellĭ) Create a new user and change the passwordĬREATE ROLE user1 WITH SUPERUSER LOGIN PASSWORD 'user1' Į) From a normal Linux user account test the connection by entering the following: Create a test database and change the user passwordĪ) Connect to the user created during the install Update the and sections with exclude=postgresql* In this tutorial we are going to use the PostgreSQL own YUM repos, which are always up-to-date and where stable releases are available instantly But without further ado let’s get to the meat of it Since Oracle took over MySQL it is the most popular free and open-source database around, even though to be fair most of the MySQL code is still open-source and free.
According to the DB-Engine database ranking it is the fourth most popular RDBMS database in the world and is gaining momentum.
I recently installed the two and faced a few issues, so I thought it might be helpful to write a synthetic article about the set up and the hurdles I had to pass, just in case anybody else is facing the same obstacles.įirst let me introduce shortly PostgreSQL, it is an open-source database from the PostgreSQL Global Development Group and there has been increasing interest in it over the past few years. Today I am writing my first article on Linkedin, and this article won’t be a general overview of a technology or providing some business insights, it will be about setting up PostgreSQL 10 in Centos 7 and joining it pgAdmin for management.
