How to choose a database for GitLab on CentOS
Apr 14, 2025 pm 04:48 PMGitLab 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.

When handling NULL values ??in MySQL, please note: 1. When designing the table, the key fields are set to NOTNULL, and optional fields are allowed NULL; 2. ISNULL or ISNOTNULL must be used with = or !=; 3. IFNULL or COALESCE functions can be used to replace the display default values; 4. Be cautious when using NULL values ??directly when inserting or updating, and pay attention to the data source and ORM framework processing methods. NULL represents an unknown value and does not equal any value, including itself. Therefore, be careful when querying, counting, and connecting tables to avoid missing data or logical errors. Rational use of functions and constraints can effectively reduce interference caused by NULL.

Turn on MySQL slow query logs and analyze locationable performance issues. 1. Edit the configuration file or dynamically set slow_query_log and long_query_time; 2. The log contains key fields such as Query_time, Lock_time, Rows_examined to assist in judging efficiency bottlenecks; 3. Use mysqldumpslow or pt-query-digest tools to efficiently analyze logs; 4. Optimization suggestions include adding indexes, avoiding SELECT*, splitting complex queries, etc. For example, adding an index to user_id can significantly reduce the number of scanned rows and improve query efficiency.

mysqldump is a common tool for performing logical backups of MySQL databases. It generates SQL files containing CREATE and INSERT statements to rebuild the database. 1. It does not back up the original file, but converts the database structure and content into portable SQL commands; 2. It is suitable for small databases or selective recovery, and is not suitable for fast recovery of TB-level data; 3. Common options include --single-transaction, --databases, --all-databases, --routines, etc.; 4. Use mysql command to import during recovery, and can turn off foreign key checks to improve speed; 5. It is recommended to test backup regularly, use compression, and automatic adjustment.

MySQL paging is commonly implemented using LIMIT and OFFSET, but its performance is poor under large data volume. 1. LIMIT controls the number of each page, OFFSET controls the starting position, and the syntax is LIMITNOFFSETM; 2. Performance problems are caused by excessive records and discarding OFFSET scans, resulting in low efficiency; 3. Optimization suggestions include using cursor paging, index acceleration, and lazy loading; 4. Cursor paging locates the starting point of the next page through the unique value of the last record of the previous page, avoiding OFFSET, which is suitable for "next page" operation, and is not suitable for random jumps.

MySQL transactions and lock mechanisms are key to concurrent control and performance tuning. 1. When using transactions, be sure to explicitly turn on and keep the transactions short to avoid resource occupation and undolog bloating due to long transactions; 2. Locking operations include shared locks and exclusive locks, SELECT...FORUPDATE plus X locks, SELECT...LOCKINSHAREMODE plus S locks, write operations automatically locks, and indexes should be used to reduce the lock granularity; 3. The isolation level is repetitively readable by default, suitable for most scenarios, and modifications should be cautious; 4. Deadlock inspection can analyze the details of the latest deadlock through the SHOWENGINEINNODBSTATUS command, and the optimization methods include unified execution order, increase indexes, and introduce queue systems.

GROUPBY is used to group data by field and perform aggregation operations, and HAVING is used to filter the results after grouping. For example, using GROUPBYcustomer_id can calculate the total consumption amount of each customer; using HAVING can filter out customers with a total consumption of more than 1,000. The non-aggregated fields after SELECT must appear in GROUPBY, and HAVING can be conditionally filtered using an alias or original expressions. Common techniques include counting the number of each group, grouping multiple fields, and filtering with multiple conditions.
