# 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/lib/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

## - secure-file-priv
|
||||
## -
|
||||
## - This variable is used to limit the effect of data import and export operations,
|
||||
## - such as those performed by the LOAD DATA and SELECT ... INTO OUTFILE statements
|
||||
## - and the LOAD_FILE() function. These operations are permitted only to users who
|
||||
## - have the FILE privilege.
|
||||
## -
|
||||
## - i.e.: GRANT FILE on *.* to piwik@localhost
|
||||
## -
|
||||
## - secure_file_priv may be set as follows:
|
||||
## -
|
||||
## - - If empty, the variable has no effect. (That means no restrictions).
|
||||
## - This is not a secure setting.
|
||||
## - - If set to the name of a directory, the server limits import and export
|
||||
## - operations to work only with files in that directory. The directory
|
||||
## - must exist; the server will not create it.
|
||||
## - - If set to NULL, the server disables import and export operations.
|
||||
## - This value is permitted as of MySQL 5.7.6.
|
||||
## -
|
||||
## - Since MySQL v 5.7.16 the default 'secure_file_priv' value has changed
|
||||
## -
|
||||
## - NULL (>= MySQL 5.7.16), empty (< MySQL 5.7.16)
|
||||
## -
|
||||
## - We use empty ("")
|
||||
## -
|
||||
## - Note:
|
||||
## - We changed the default to empty ("") while building from source
|
||||
## - using CMake option (-DINSTALL_SECURE_FILE_PRIVDIR=""). So you can ignore
|

## - this option.

|

## - local-infile
|

## -
|
||||
## - This variable controls server-side LOCAL capability for LOAD DATA statements.
|
||||
## - Depending on the local_infile setting, the server refuses or permits local data
|
||||
## - loading by clients that have LOCAL enabled on the client side.
|
||||
## -
|
||||
## - You can check your 'local-infile' setting on mysql prompt:

#local-infile = 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

## - If you do not specify any InnoDB log variables, the default is
|
||||
## - to create two files named ib_logfile0 and ib_logfile1 in the MySQL

## -
|

## - You can set .._buffer_pool_size up to 50 - 80 %
|

## - of RAM but beware of setting memory usage too high
|
||||
## -
|
||||
## - Note:
|
||||
## - When the size of the buffer pool is greater than 1GB, setting
|
||||
## - innodb_buffer_pool_instances to a value greater than 1 can improve
|

# 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

# The port the master is listening on.

# optional - defaults to 3306

|
||||
## - Note:
|

|
||||
## -
|
||||
## - You can check whether you need to increase the table cache by checking
|
||||
## - the Opened_tables status variable. If the value of Opened_tables is large
|
||||
## - and you do not use FLUSH TABLES often (which just forces all tables to be
