# Example MySQL config file for medium systems. # # This isfor a systemwith little memory (32M -64M) where MySQL plays # an important part, or systems up to128M where MySQL is used together with # other programs (such as a web server) # # You can copy this file to # /etc/my.cnf tosetglobal options, # mysql-data-dir/my.cnf toset server-specific options (in this # installation this directory is/var/lib/mysql) or # ~/.my.cnf tosetuser-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 toall MySQL clients [client] port =3306 socket =/var/lib/mysql/mysql.sock default-character-set= utf8
# Here follows entries forsomespecific programs

# required unique id between1and2^32-1 # defaults to1 if master-host isnotset # but will notfunctionas 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 between2and2^32-1 # (and different from the master) # defaults to2 if master-host isset # but will notfunctionas 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 withwhen connecting to # the master - required #master-password =<password> # # The port the master is listening on. # optional - defaults to3306 #master-port =<port> # # binary logging -not required for slaves, but recommended #log-bin=mysql-bin
