merhaba, özellikle key_buffer gibi değerlerle oynaman sorununu giderecektir sanırım.
mümkün olduğu kadar veri alışverişinin hafızada tutulmasını sağla. kendi my.cnf yapılandırmam aşağıda, umarım yardımcı olur. # 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. # # You can copy this file to # /etc/my.cnf to set global options, # mysql-data-dir/my.cnf to set server-specific options (in this # installation this directory is /var/db/mysql) or # ~/.my.cnf to set user-specific options. # # 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 = /tmp/mysql.sock # Here follows entries for some specific programs # The MySQL server [mysqld] log-slow-queries = /var/db/mysql/mysql-slow.log long_query_time = 10 back_log = 100 port = 3306 socket = /tmp/mysql.sock skip-locking #skip-innodb max_connections = 1024 #key_buffer = 1536M key_buffer = 2048M max_allowed_packet = 2M table_cache = 1024 sort_buffer_size = 4M read_buffer_size = 4M read_rnd_buffer_size = 16M myisam_sort_buffer_size = 128M thread_cache_size = 8 query-cache-type = 1 query_cache_size = 1024M max_heap_table_size = 256M # Try number of CPU's*2 for thread_concurrency thread_concurrency = 2 # 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 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 # Point the following paths to different dedicated disks #tmpdir = /tmp/ #log-update = /path-to-dedicated-directory/hostname # Uncomment the following if you are using BDB tables #bdb_cache_size = 384M #bdb_max_lock = 100000 # Uncomment the following if you are using InnoDB tables #innodb_data_home_dir = /var/db/mysql/ #innodb_data_file_path = ibdata1:2000M;ibdata2:10M:autoextend #innodb_log_group_home_dir = /var/db/mysql/ #innodb_log_arch_dir = /var/db/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 [isamchk] key_buffer = 256M sort_buffer_size = 256M read_buffer = 2M sort_buffer_size = 256M read_buffer = 2M write_buffer = 2M [myisamchk] key_buffer = 256M sort_buffer_size = 256M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout 27.03.2008 tarihinde Mesut GÜLNAZ <[EMAIL PROTECTED]> yazmış: > > Anlık ziyaretçi sayısı 3000 olan ve quad-core 2 adet CPU nun yanında 8GB > de RAM e sahip olan bir sunucunun host ettiği, bir sitenin kullandığı mysql > db sinin my.cnf dosyasında yer alan değişkenler şu şekilde.
