Installing PostgreSQL using YUMīy default, CentOS 7 includes PostgreSQL in the base yum repositories. We recommend a GoDaddy VPS if you’re just getting started, or a full dedicated server if you’re ready to take total control. In order to perform this task, you’ll need an active CentOS 7 server, as well as an SSH client such as PuTTY (for Windows) or Terminal (Mac). Now let’s focus on the nitty-gritty - how to install and setup PostgreSQL on your server. We highly suggest doing research on the different database platforms at their respective sites before making an informed decision. If you want to use the more ubiquitous platform, high security, and work mostly with website CMS platforms, MySQL is still probably the right fit for you.If you want stronger security, compliance, stored procedures, and need a database for a strong back-end application, Postgres might be the right fit for you.However, in our research we have found that there are a few guidelines you can follow when making your decision: Like many software solutions, which database system you should use depends entirely on the project at hand. Different SQL syntax than traditional MySQL/Microsoft SQL solutions.Less popularity = less open-source documentation and collaboration.Struggles with large read-heavy operations against a database.An open-source SQL standard compliant RDBMS.This isn’t saying you should immediately dump MySQL for Postgres for all your applications or projects - but it might be a good fit for some. It also supports stored procedures, a feature that MySQL does not support.

PostgreSQL, or simply ‘postgres,’ is an open-source relational database management system, or RDBMS for short. This article will assist you with installing and configuring PostgreSQL on your self-managed Linux CentOS 7 server. Some of the more up-and-coming web development stacks such as LEPP, Gunicorn/Django, and Ruby/Rails prefer to use the PostgreSQL database platform instead of the more traditional MySQL configuration.
