# Example MySQL config file for medium systems. # # This is for a system with little memory (32M - 64M) where MySQL plays # an important part, or systems up to 128M where MySQL is used together with # other programs (such as a web server) # # 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 C:/mysql/data) 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] basedir = "C:/MySQL5" datadir = "C:/MySQL5/data" default-character-set=utf8  port  = 3306 socket  = /tmp/mysql.sock skip-locking key_buffer = 16M max_allowed_packet = 1M table_cache = 64 sort_buffer_size = 512K net_buffer_length = 8K read_buffer_size = 256K read_rnd_buffer_size = 512K myisam_sort_buffer_size = 8M  # Don't listen on a TCP/IP port at all. This can be a security enhancement, # if all processes that need to connect to mysqld run on the same host. # All interaction with mysqld must be made via Unix sockets or named pipes. # Note that using this option without enabling named pipes on Windows # (via the "enable-named-pipe" option) will render mysqld useless! #  #skip-networking  # Disable Federated by default skip-federated  # Replication Master Server (default) # binary logging is required for replication log-bin=mysql-bin  # required unique id between 1 and 2^32 - 1 # defaults to 1 if master-host is not set # but will not function as a master if omitted server-id = 1  # Replication Slave (comment out master section to use this) # # To configure this host as a replication slave, you can choose between # two methods : # # 1) Use the CHANGE MASTER TO command (fully described in our manual) - #    the syntax is: # #    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>, #    MASTER_USER=<user>, MASTER_PASSWORD=<password> ; # #    where you replace <host>, <user>, <password> by quoted strings and #    <port> by the master's port number (3306 by default). # #    Example: # #    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306, #    MASTER_USER='joe', MASTER_PASSWORD='secret'; # # OR # # 2) Set the variables below. 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  # 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 = 4M #bdb_max_lock = 10000  # Uncomment the following if you are using InnoDB tables #innodb_data_home_dir = C:/mysql/data/ #innodb_data_file_path = ibdata1:10M:autoextend #innodb_log_group_home_dir = C:/mysql/data/ #innodb_log_arch_dir = C:/mysql/data/ # You can set .._buffer_pool_size up to 50 - 80 % # of RAM but beware of setting memory usage too high #innodb_buffer_pool_size = 16M #innodb_additional_mem_pool_size = 2M # Set .._log_file_size to 25 % of buffer pool size #innodb_log_file_size = 5M #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 = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M  [myisamchk] key_buffer = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M  [mysqlhotcopy] interactive-timeout
