Password Expiration Policy
|
||||||
|
==========================
|
||||||
|
|
||||||
|
# default_password_lifetime
|
||||||
|
#
|
||||||
|
# This variable defines the global automatic password expiration policy. It applies
|
||||||
|
# to accounts that use MySQL built-in authentication methods (accounts that use an
|
||||||
|
# authentication plugin of mysql_native_password, mysql_old_password, or sha256_password).
|
||||||
|
#
|
||||||
|
# The default default_password_lifetime value is 0, which disables automatic password
|
||||||
|
# expiration. If the value of default_password_lifetime is a positive integer N, it
|
||||||
|
# indicates the permitted password lifetime; passwords must be changed every N days.
|
||||||
|
|
||||||
|
# The global password expiration policy can be overridden as desired for individual
|
||||||
|
# accounts using the ALTER USER statement. See Section 7.3.6, “Password Expiration Policy”.
|
||||||
|
#
|
||||||
|
# ! Note !
|
||||||
|
#
|
||||||
|
# From MySQL 5.7.4 to 5.7.10, the default default_password_lifetime value is 360 (passwords
|
||||||
|
# must be changed approximately once per year). For those versions, be aware that, if you
|
||||||
|
# make no changes to the default_password_lifetime variable or to individual user accounts,
|
||||||
|
# all user passwords will expire after 360 days, and all user accounts will start running
|
||||||
|
# in restricted mode when this happens. Clients (which are effectively users) connecting to
|
||||||
|
# the server will then get an error indicating that the password must be changed:
|
||||||
|
# ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing
|
||||||
|
# this statement.
|
||||||
|
|
||||||
|
# However, this is easy to miss for clients that automatically connect to the server, such
|
||||||
|
# as connections made from scripts. To avoid having such clients suddenly stop working due
|
||||||
|
# to a password expiring, make sure to change the password expiration settings for those clients,
|
||||||
|
# like this:
|
||||||
|
#
|
||||||
|
# ALTER USER 'script'@'localhost' PASSWORD EXPIRE NEVER
|
||||||
|
#
|
||||||
|
# Alternatively, set the default_password_lifetime variable to 0, thus disabling automatic
|
||||||
|
# password expiration for all users.
|
||||||
|
#
|
||||||
|
default_password_lifetime = 0

|

|
#
|

|
# 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>

## - 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

|
||||||
|
## - reducing contention as different threads read and write to cached pages.

# 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

||||||
|

#
|

# 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)

# 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)
|
||||||
|
#
|
||||||
|

# (and different from the master)

#
|

|
# 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

|

|
#
|

|
# 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>
|
||||||
|
#
|

|
