How to choose a database for GitLab on CentOS
GitLab database deployment guide on CentOS system
Choosing the right database is a key step in successfully deploying GitLab. GitLab is compatible with a variety of databases, including MySQL, PostgreSQL, and MongoDB. This article will explain in detail how to select and configure these databases.
Database selection suggestions
MySQL: A widely used relational database management system (RDBMS) with stable performance and suitable for most GitLab deployment scenarios.
PostgreSQL: Powerful open source RDBMS, supports complex queries and advanced features, suitable for handling large data sets.
MongoDB: A popular NoSQL database, good at processing massive unstructured data, with high performance and scalability.
Detailed explanation of database configuration
MySQL configuration
- Install MySQL server through the terminal:
sudo yum install mysql-server
- After the installation is complete, start the MySQL service and set it to boot:
sudo systemctl start mysqld sudo systemctl enable mysqld
- Set MySQL root user password:
sudo mysql_secure_installation
PostgreSQL configuration
- Install PostgreSQL server using the following command:
sudo yum install postgresql-server
- Initialize the database:
sudo postgresql-setup initdb
- Start PostgreSQL service and set to boot:
sudo systemctl start postgresql sudo systemctl enable postgresql
- Create a new database user:
sudo -u postgres createuser --interactive
MongoDB configuration
- Install MongoDB through the terminal:
sudo yum install mongodb-org
- After the installation is complete, start the MongoDB service and set it to boot:
sudo systemctl start mongod sudo systemctl enable mongod
GitLab database configuration
In the GitLab configuration file /etc/gitlab/gitlab.rb , be sure to set external_url as your server IP address or domain name. For example, the local server can be set to http://192.168.1.100 .
Important Tips
Make sure that the firewall allows GitLab to access the database port (MySQL: 3306, PostgreSQL: 5432, MongoDB: 27017).
Adjust database configuration parameters, such as memory allocation and connection pool size, according to actual needs, to optimize performance.
Hope the above steps can help you deploy GitLab database smoothly on CentOS.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
