I've generated a few errors and then checked /var/log/syslog, /var/log/mysql.log and /var/log/mysql/error.log and didn't see mysql errors in any of those files. The 2 mysql files were empty and I didn't see any mysql errors in syslog. Here is the what the logging portion of my.cnf looks like. Code: # * Logging and Replication # # Both location gets rotated by the cronjob. # Be aware that this log type is a performance killer. # As of 5.1 you can enable the log at runtime! #general_log_file = /var/log/mysql/mysql.log #general_log = 1 log_error = /var/log/mysql/error.log # Here you can see queries with especially long duration #log_slow_queries = /var/log/mysql/mysql-slow.log #long_query_time = 2 #log-queries-not-using-indexes # # The following can be used as easy to replay backup logs or for replication. # note: if you are setting up a replication slave, see README.Debian about # other settings you may need to change. #server-id = 1 #log_bin = /var/log/mysql/mysql-bin.log expire_logs_days
Authored by: Jered Heeschen In the previous article we covered a basic MySQL server setup on CentOS Linux. We set the root password, created a database, and created a user for the database. Now let’s look at MySQL in a little more detail so we can tweak its configuration and be ready in case something goes wrong. Finding the config files By default you’ll find MySQL’s configuration file at: /etc/my.cnf If it’s not there, however, you can ask mysqld where it looks for its config. Run the command: /usr/libexec/mysqld --help --verbose You’ll get a flood of text back. The first part describes the options you can send to the server when you launch it. The second part is all the configuration stuff that was set when the server was compiled. What we’re looking for shows up near the start of the output. Find a couple lines that look like: Default options are read from the following files in the given order: /etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf ~/.my.cnf And there we are. The server works down that list until it finds a configuration file. my.cnf With the location in hand, open the my.cnf file and have a look inside. /etc/my.cnf Any lines starting with “#” are comments, and they mostly document what the different settings are for. They’re good to read through. You’ll find details like the location of log files and where the database files are kept. Config groups There are lines in the config file that just contain a word in square brackets, like “[client]” or “[mysqld]”. Those are “config groups” and they tell the programs that read the configuration file which parts they should pay attention to. See, while we’ve been focusing on the server part of MySQL, it’s technically a collection of tools. That includes the server (mysqld), the client (mysql), and some other tool
