# Example MySQL config file for very large systems. # # This is for a large system with memory of 1G-2G where the system runs mainly # MySQL. # # MySQL programs look for option files in a set of # locations which depend on the deployment platform. # You can copy this option file to one of those # locations. For information about these locations, see: # http://dev.mysql.com/doc/mysql/en/option-files.html # # In this file, you can use all long options that a program supports. # If you want to know which options a program supports, run the program # with the "--help" option. # The following options will be passed to all MySQL clients [client] #password = your_password port = 3306 socket = /var/lib/mysql/mysql.sock # Here follows entries for some specific programs # The MySQL server [mysqld] slow_query_log=1 slow_query_log_file=/var/log/mysql-slow.log long_query_time=5 port = 3306 socket = /var/lib/mysql/mysql.sock skip-external-locking key_buffer_size = 384M max_allowed_packet = 500M table_open_cache = 512 sort_buffer_size = 2M read_buffer_size = 2M read_rnd_buffer_size = 8M myisam_sort_buffer_size = 64M thread_cache_size = 8 query_cache_size = 32M # Try number of CPU's*2 for thread_concurrency thread_concurrency = 8 max_connections = 500 query_cache_type = 0 tmp_table_size = 64M max_heap_table_size =32M performance_schema = OFF local-infile=0 # Don't listen on a TCP/IP port at all.

However, in case you choose this method, then # start replication for the first time (even unsuccessfully, for example # if you mistyped the password in master-password and the slave fails to # connect), the slave will create a master.info file, and any later # change in this file to the variables' values below will be ignored and # overridden by the content of the master.info file, unless you shutdown # the slave server, delete master.info and restart the slaver server. # For that reason, you may want to leave the lines below untouched # (commented) and instead use CHANGE MASTER TO (see above) # # required unique id between 2 and 2^32 - 1 # (and different from the master) # defaults to 2 if master-host is set # but will not function as a slave if omitted #server-id = 2 # # The replication master for this slave - required #master-host = <hostname> # # The username the slave will use for authentication when connecting # to the master - required #master-user = <username> # # The password the slave will authenticate with when connecting to # the master - required #master-password = <password> # # The port the master is listening on. # optional - defaults to 3306 #master-port = <port> # # binary logging - not required for slaves, but recommended #log-bin=mysql-bin # # binary logging format - mixed recommended #binlog_format=mixed # Uncomment the following if you are using InnoDB tables #innodb_data_home_dir = /var/lib/mysql #innodb_data_file_path = ibdata1:2000M;ibdata2:10M:autoextend #innodb_log_group_home_dir = /var/lib/mysql # You can set .._buffer_pool_size up to 50 - 80 % # of RAM but beware of setting memory usage too high #innodb_buffer_pool_size = 384M #innodb_additional_mem_pool_size = 20M # Set .._log_file_size to 25 % of buffer pool size #innodb_log_file_size = 100M #innodb_log_buffer_size = 8M #innodb_flush_log_at_trx_commit = 1 #innodb_lock_wait_timeout = 50 [mysqldump] quick max_allowed_packet = 16M [mysql] no-auto-rehash # Remove the next comment character if you are not familiar with SQL #safe-updates [myisamchk] key_buffer_size = 256M sort_buffer_size = 256M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout

-------- Recommendations ---------------------------------------------------------------------------
General recommendations:
Control error line(s) into /var/lib/mysql/srv.manga-tr.com.err file
Remove Anonymous User accounts - there are 2 anonymous accounts.
MySQL started within last 24 hours - recommendations may be inaccurate
Configure your accounts with ip or subnets only, then update your configuration with skip-name-resolve=1
Adjust your join queries to always utilize indexes
When making adjustments, make tmp_table_size/max_heap_table_size equal
Reduce your SELECT DISTINCT queries which have no LIMIT clause
Increase table_open_cache gradually to avoid file descriptor limits
Read this before increasing table_open_cache over 64: http://bit.ly/1mi7c4C
Beware that open_files_limit (2500) variable
should be greater than table_open_cache (512)
Optimize queries and/or use InnoDB to reduce lock wait
Performance shouldn't be activated for MySQL and MariaDB 5.5 and lower version
Consider installing Sys schema from https://github.com/mysql/mysql-sys
Variables to adjust:
join_buffer_size (> 128.0K, or always use indexes with joins)
tmp_table_size (> 64M)
max_heap_table_size (> 32M)
table_open_cache (> 512)
performance_schema = OFF disable PFS
innodb_file_per_table=ON
innodb_log_file_size * innodb_log_files_in_group should be equals to 1/4 of buffer pool size (=64M) if possible.Ne gibi değişiklikler yapmalıyım. Yardımlarınızı bekliyorum.
