MySQL Installation and Architecture · Installation and configuration
Scenario: A database administrator is configuring a new Linux-based MySQL Enterprise Server.
The administrator creates a configuration file at /etc/my.cnf setting max_connections=500. However, a developer also places a .my.cnf file in the mysql user's home directory setting max_connections=200.
When the administrator starts the mysqld service using the default systemd startup scripts, what will be the effective value of max_connections, and why?
Answer and explanation
Correct answer: B
MySQL reads option files in a specific sequence. On Unix/Linux, it typically reads /etc/my.cnf, then /etc/mysql/my.cnf, then SYSCONFDIR/my.cnf, then $MYSQL_HOME/my.cnf, and finally ~/.my.cnf. Because the user-specific file is read last, any conflicting variables defined there will override the values set in the global files.
