Someone Take a Look at My.cnf MySQL File - High MYSQL Ram Usage
Seeing people running around on unimaginable low mysql usage cases on low ram boxes, I'm wondering why mysql is using seemingly so much FNG ram.
I hope that's visible. I'd like to know how to configure mysql to run optimised on my Digitalocean server.
Here's my.cnf:
[email protected]:~$ cat /etc/mysql/my.cnf # # The MySQL database server configuration file. # # You can copy this to one of: # - "/etc/mysql/my.cnf" to set global options, # - "~/.my.cnf" to set user-specific options. # # One can use all long options that the program supports. # Run program with --help to get a list of available options and with # --print-defaults to see which it would actually understand and use. # # For explanations see # http://dev.mysql.com/doc/mysql/en/server-system-variables.html #ref http://stackoverflow.com/questions/1178736/mysql-maximum-memory-usage table_definition_cache = 400 < -- mysql doesn't restart with this uncomment, but reloads fine with service mysql reload .. hmpf # This will be passed to all mysql clients # It has been reported that passwords should be enclosed with ticks/quotes # escpecially if they contain "#" chars... # Remember to edit /etc/mysql/debian.cnf when changing the socket location. [client] port = 3306 socket = /var/run/mysqld/mysqld.sock # Here is entries for some specific programs # The following values assume you have at least 32M ram # This was formally known as [safe_mysqld]. Both versions are currently parsed. [mysqld_safe] socket = /var/run/mysqld/mysqld.sock nice = 0 [mysqld] # # * Basic Settings # user = mysql pid-file = /var/run/mysqld/mysqld.pid socket = /var/run/mysqld/mysqld.sock port = 3306 basedir = /usr datadir = /var/lib/mysql tmpdir = /tmp lc-messages-dir = /usr/share/mysql skip-external-locking # # Instead of skip-networking the default is now to listen only on # localhost which is more compatible and is not less secure. bind-address = 127.0.0.1 # # * Fine Tuning # key_buffer = 8M max_allowed_packet = 16M thread_stack = 128K thread_cache_size = 4 # This replaces the startup script and checks MyISAM tables if needed # the first time they are touched myisam-recover = BACKUP #max_connections = 100 #table_cache = 64 #thread_concurrency = 10 # # * Query Cache Configuration # query_cache_limit = 512K query_cache_size = 8M # # * 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 # # Error log - should be very few entries. # 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 = 10 max_binlog_size = 100M #binlog_do_db = include_database_name #binlog_ignore_db = include_database_name # # * InnoDB # # InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/. # Read the manual for more InnoDB related options.

I'm a peasant so have mercy on me.
Willing to cooperate to show command outputs if that helps.
Edit: server runs on Digitalocean 1GB Plan with free serverpilot and minimal personal customisation made by me.
Server runs 2 domains, 1 empty, one having wordpress in root, piwik and owncloud in subfolders, so 3 db-s in total on server.
Mysql is on localhost.

Ah how kind of you
But really, what's wrong with 92MB RAM?
I'm trying to optimise. Seeing people running sites on servers with lower amount of ram, I see no reason why I shouldn't try to optimise.
Plus, the server barely gets any visitors.

If this is the standard mysql, add the following under [mysql] block
performance_schema = 0Devops Consultant | GitHub
Add this
Restart mysql. Tadaa.
edit: Use nginx + ph5-fpm for lower ram usage.
