=head1 NAME
|
|
|
|
pt-config-diff - Diff MySQL configuration files and server variables.
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
Usage: pt-config-diff [OPTIONS] CONFIG CONFIG [CONFIG...]
|
|
|
|
pt-config-diff diffs MySQL configuration files and server variables.
|
|
CONFIG can be a filename or a DSN. At least two CONFIG sources must be given.
|
|
Like standard Unix diff, there is no output if there are no differences.
|
|
|
|
Diff host1 config from SHOW VARIABLES against host2:
|
|
|
|
pt-config-diff h=host1 h=host2
|
|
|
|
Diff config from [mysqld] section in my.cnf against host1 config:
|
|
|
|
pt-config-diff /etc/my.cnf h=host1
|
|
|
|
Diff the [mysqld] section of two option files:
|
|
|
|
pt-config-diff /etc/my-small.cnf /etc/my-large.cnf
|
|
|
|
=head1 RISKS
|
|
|
|
Percona Toolkit is mature, proven in the real world, and well tested,
|
|
but all database tools can pose a risk to the system and the database
|
|
server. Before using this tool, please:
|
|
|
|
=over
|
|
|
|
=item * Read the tool's documentation
|
|
|
|
=item * Review the tool's known L<"BUGS">
|
|
|
|
=item * Test the tool on a non-production server
|
|
|
|
=item * Backup your production server and verify the backups

|
|
=head1 DESCRIPTION
|
|
|
|
pt-config-diff diffs MySQL configurations by examining the values of server
|
|
system variables from two or more CONFIG sources specified on the command
|
|
line. A CONFIG source can be a DSN or a filename containing the output of
|
|
C<mysqld --help --verbose>, C<my_print_defaults>, C<SHOW VARIABLES>, or
|
|
an option file (e.g. my.cnf).
|
|
|
|
For each DSN CONFIG, pt-config-diff connects to MySQL and gets variables
|
|
and values by executing C<SHOW /*!40103 GLOBAL*/ VARIABLES>. This is
|
|
an "active config" because it shows what server values MySQL is
|
|
actively (currently) running with.
|
|
|
|
Only variables that all CONFIG sources have are compared because if a
|
|
variable is not present then we cannot know or safely guess its value.
|
|
For example, if you compare an option file (e.g. my.cnf) to an active config
|
|
(i.e. SHOW VARIABLES from a DSN CONFIG), the option file will probably
|
|
only have a few variables, whereas the active config has every variable.
|
|
Only values of the variables present in both configs are compared.
|
|
|
|
Option file and DSN configs provide the best results.
|
|
|
|
=head1 OUTPUT
|
|
|
|
There is no output when there are no differences. When there are differences,
|
|
pt-config-diff prints a report to STDOUT that looks similar to the following:
|
|
|
|
2 config differences
|
|
Variable my.master.cnf my.slave.cnf
|
|
========================= =============== ===============
|
|
datadir /tmp/12345/data /tmp/12346/data
|
|
port 12345 12346
|
|
|
|
Comparing MySQL variables is difficult because there are many variations and
|
|
subtleties across the many versions and distributions of MySQL. When a
|
|
comparison fails, the tool prints a warning to STDERR, such as the following:
|
|
|
|
Comparing log_error values (mysqld.log, /tmp/12345/data/mysqld.log)
|
|
caused an error: Argument "/tmp/12345/data/mysqld.log" isn't numeric
|
|
in numeric eq (==) at ./pt-config-diff line 2311.
|
|
|
|
Please report these warnings so the comparison functions can be improved.
|
|
|
|
=head1 EXIT STATUS
|
|
|
|
pt-config-diff exits with a zero exit status when there are no differences, and
|
|
1 if there are.
|
|
|
|
=head1 OPTIONS
|
|
|
|
This tool accepts additional command-line arguments. Refer to the
|
|
L<"SYNOPSIS"> and usage information for details.
|
|
|
|
=over
|
|
|
|
=item --ask-pass
|
|
|
|
Prompt for a password when connecting to MySQL.
|
|
|
|
=item --charset
|
|
|
|
short form: -A; type: string
|
|
|
|
Default character set. If the value is utf8, sets Perl's binmode on
|
|
STDOUT to utf8, passes the mysql_enable_utf8 option to DBD::mysql, and
|
|
runs SET NAMES UTF8 after connecting to MySQL. Any other value sets
|
|
binmode on STDOUT without the utf8 layer, and runs SET NAMES after
|
|
connecting to MySQL.
|
|
|
|
=item --config
|
|
|
|
type: Array
|
|
|
|
Read this comma-separated list of config files; if specified, this must be the
|
|
first option on the command line. (This option does not specify a CONFIG;
|
|
it's equivalent to C<--defaults-file>.)
|
|
|
|
=item --database
|
|
|
|
short form: -D; type: string
|
|
|
|
Connect to this database.
|
|
|
|
=item --defaults-file
|
|
|
|
short form: -F; type: string
|
|
|
|
Only read mysql options from the given file. You must give an absolute
|
|
pathname.
|
|
|
|
=item --help
|
|
|
|
Show help and exit.
|
|
|
|
=item --host
|
|
|
|
short form: -h; type: string
|
|
|
|
Connect to host.
|
|
|
|
=item --[no]ignore-case
|
|
|
|
default: yes
|
|
|
|
Compare the variables case-insensitively.
|
|
|
|
=item --ignore-variables
|
|
|
|
type: array
|
|
|
|
Ignore, do not compare, these variables.
|
|
|
|
=item --password
|
|
|
|
short form: -p; type: string
|
|
|
|
Password to use for connection.
|
|
|
|
=item --pid
|
|
|
|
type: string
|
|
|
|
Create the given PID file. The tool won't start if the PID file already
|
|
exists and the PID it contains is different than the current PID. However,
|
|
if the PID file exists and the PID it contains is no longer running, the
|
|
tool will overwrite the PID file with the current PID. The PID file is
|
|
removed automatically when the tool exits.
|
|
|
|
=item --port
|
|
|
|
short form: -P; type: int
|
|
|
|
Port number to use for connection.
|
|
|
|
=item --[no]report
|
|
|
|
default: yes
|
|
|
|
Print the MySQL config diff report to STDOUT. If you just want to check
|
|
if the given configs are different or not by examining the tool's exit
|
|
status, then specify C<--no-report> to suppress the report.
|
|
|
|
=item --report-width
|
|
|
|
type: int; default: 78
|
|
|
|
Truncate report lines to this many characters. Since some variable values can
|
|
be long, or when comparing multiple configs, it may help to increase the
|
|
report width so values are not truncated beyond readability.
|
|
|
|
=item --set-vars
|
|
|
|
type: Array
|
|
|
|
Set the MySQL variables in this comma-separated list of C<variable=value> pairs.
|
|
|
|
By default, the tool sets:
|
|
|
|
=for comment ignore-pt-internal-value
|
|
MAGIC_set_vars
|
|
|
|
wait_timeout=10000
|
|
|
|
Variables specified on the command line override these defaults. For
|
|
example, specifying C<--set-vars wait_timeout=500> overrides the defaultvalue of C<10000>.
|
|
|
|
The tool prints a warning and continues if a variable cannot be set.
|
|
|
|
=item --socket
|
|
|
|
short form: -S; type: string
|
|
|
|
Socket file to use for connection.
|
|
|
|
=item --user
|
|
|
|
short form: -u; type: string
|
|
|
|
MySQL user if not current user.
|
|
|
|
=item --version
|
|
|
|
Show version and exit.
|
|
|
|
=item --[no]version-check
|
|
|
|
default: yes
|
|
|
|
Check for the latest version of Percona Toolkit, MySQL, and other programs.
|
|
|
|
This is a standard "check for updates automatically" feature, with two
|
|
additional features. First, the tool checks its own version and also the
|
|
versions of the following software: operating system, Percona Monitoring and
|
|
Management (PMM), MySQL, Perl, MySQL driver for Perl (DBD::mysql), and
|
|
Percona Toolkit. Second, it checks for and warns about versions with known
|
|
problems. For example, MySQL 5.5.25 had a critical bug and was re-released
|
|
as 5.5.25a.
|
|
|
|
A secure connection to Percona's Version Check database server is done to
|
|
perform these checks. Each request is logged by the server, including software
|
|
version numbers and unique ID of the checked system. The ID is generated by the
|
|
Percona Toolkit installation script or when the Version Check database call is
|
|
done for the first time.
|
|
|
|
Any updates or known problems are printed to STDOUT before the tool's normal
|
|
output. This feature should never interfere with the normal operation of the
|
|
tool.

=head1 DSN OPTIONS
|
|
|
|
These DSN options are used to create a DSN. Each option is given like
|
|
C<option=value>. The options are case-sensitive, so P and p are not the
|
|
same option. There cannot be whitespace before or after the C<=> and
|
|
if the value contains whitespace it must be quoted. DSN options are
|
|
comma-separated. See the L<percona-toolkit> manpage for full details.
|

=head1 ENVIRONMENT
|
|
|
|
The environment variable C<PTDEBUG> enables verbose debugging output to STDERR.
|
|
To enable debugging and capture all output to a file, run the tool like:
|
|
|
|
PTDEBUG=1 pt-config-diff ... > FILE 2>&1
|
|
|
|
Be careful: debugging output is voluminous and can generate several megabytes
|
|
of output.
|
|
|
|
=head1 ATTENTION
|
|
|
|
Using <PTDEBUG> might expose passwords. When debug is enabled, all command line
|
|
parameters are shown in the output.
|
|
|
|
=head1 SYSTEM REQUIREMENTS
|
|
|
|
You need Perl, DBI, DBD::mysql, and some core packages that ought to be
|
|
installed in any reasonably new version of Perl.
|
|
|
|

=head1 ABOUT PERCONA TOOLKIT
|
|
|
|
This tool is part of Percona Toolkit, a collection of advanced command-line
|
|
tools for MySQL developed by Percona. Percona Toolkit was forked from two
|
|
projects in June, 2011: Maatkit and Aspersa. Those projects were created by
|
|
Baron Schwartz and primarily developed by him and Daniel Nichter. Visit
|
