MySQL utilities are set of scripts provided for DBAs for general database administration. These are basically command line utilities which can be used to perform various tasks.

Following is the listing of MySQL utility version 1.3 that I installed in my environment

You can find the complete usage of these scripts in official documentation of mysql utilities. I have provided the link for the same in reference section of this article.

I will cover the installation part of MySQL utilities in this article.

Step 1) Download MySQL utilities from http://dev.mysql.com/downloads/tools/utilities/ location

Select the OS as “Linux – Generic” and download .tar.gz file

Step 2) Extract the file

Copy the file to the server on which you have installed MySQL or on any server where you want to install utilities and extract the tar file.

In my case I am going to install this on my desktop where MySQL is running

So my tar file is residing at /home/advait/mysql/mysql-utilities-1.3.6.tar.gz

I can extract the content in one of the directory under my MySQL installation.

So I extracted above tar file at /usr/local/mysql

cd /usr/local/mysql

tar xvfz /home/advait/mysql/mysql-utilities-1.3.6.tar.gz

Step 3) Build and install utilities

Once you extract you will see mysql-utilities-1.3.6 directory. Inside this directory we set setup.py

Use setup.py to build and install utilities

Build should be done using mysql (non root) user. In my case I am using advait user to start/stop and manage mysql. So I will build using advait user

python setup.py build

advait.desktop$ python setup.py build
running build
running build_py
creating build
creating build/lib
creating build/lib/mysql
copying mysql/__init__.py -> build/lib/mysql
creating build/lib/mysql/utilities
copying mysql/utilities/exception.py -> build/lib/mysql/utilities
copying mysql/utilities/__init__.py -> build/lib/mysql/utilities
creating build/lib/mysql/utilities/command
copying mysql/utilities/command/read_frm.py -> build/lib/mysql/utilities/command
copying mysql/utilities/command/rpl_admin.py -> build/lib/mysql/utilities/command
copying mysql/utilities/command/serverinfo.py -> build/lib/mysql/utilities/command
copying mysql/utilities/command/utilitiesconsole.py -> build/lib/mysql/utilities/command
...
changing mode of build/scripts-2.7/mysqlserverclone from 644 to 755
changing mode of build/scripts-2.7/mysqldbcompare from 644 to 755
changing mode of build/scripts-2.7/mysqlserverinfo from 644 to 755
changing mode of build/scripts-2.7/mysqluserclone from 644 to 755

Install should be done using “root” user since we have installed MySQL using root user. If you use any other user (other than root), that user may not have permissions on python libraries and so install can fail.

advaitd-2.desktop$ python setup.py install
running install
running build
running build_py
running build_scripts
running install_lib
creating /usr/local/lib/python2.7/site-packages/mysql
copying build/lib/mysql/__init__.py -> /usr/local/lib/python2.7/site-packages/mysql
creating /usr/local/lib/python2.7/site-packages/mysql/utilities
copying build/lib/mysql/utilities/exception.py -> /usr/local/lib/python2.7/site-packages/mysql/utilities
creating /usr/local/lib/python2.7/site-packages/mysql/utilities/common
copying build/lib/mysql/utilities/common/lock.py -> /usr/local/lib/python2.7/site-packages/mysql/utilities/common
...
changing mode of /usr/local/bin/mysqldbexport to 755
changing mode of /usr/local/bin/mysqldbimport to 755
changing mode of /usr/local/bin/mysqlindexcheck to 755
changing mode of /usr/local/bin/mysqlrplcheck to 755
changing mode of /usr/local/bin/mysqlserverinfo to 755
changing mode of /usr/local/bin/mysqlfrm to 755
running install_egg_info

Step 4) Testing

Once install is done, you can verify running one of the script if things are working fine.

All MySQL utilities will get installed at /usr/local/bin directory and they should be part of PATH variable. So no need to give complete path.

Example:

advait.desktop$ mysqldiskusage --server=root:<password>@localhost
# Source on localhost: ... connected.
# Database totals:
+---------------------+------------+
| db_name | total |
+---------------------+------------+
| deo | 546,720 |
| mysql | 1,542,216 |
| performance_schema | 396,071 |
+---------------------+------------+
Total database disk usage = 2,485,007 bytes or 2.37 MB
#...done.

You might face following error if python connector module is not installed

advait.desktop$ mysqldiskusage --server=root:<password>@localhost
Traceback (most recent call last):
 File "/usr/local/bin/mysqldiskusage", line 35, in <module>
 from mysql.utilities.common.server import connect_servers
 File "/usr/local/lib/python2.7/site-packages/mysql/utilities/common/server.py", line 31, in <module>
 import mysql.connector
ImportError: No module named connector

If you face this issue, you need to install python connector from http://dev.mysql.com/downloads/connector/python/ location

Step 5) Installing python connector

Again download the connector from http://dev.mysql.com/downloads/connector/python/ location

scp the same to the machine on which you were installing MySQL utilities

Extract the .tar.gz file to one of the directories in MySQL installation. In my case I am installing them under utilities directory – /usr/local/mysql/mysql-utilities-1.3.6

Build using non-root user (advait in my case).
