2.1.4.1. Verifying the MD5 Checksum
After you have downloaded a MySQL package, you should make
sure that its MD5 checksum matches the one provided on the
MySQL download pages. Each package has an individual checksum
that you can verify with the following command, where
package_name is the name of the
package you downloaded:
shell> md5sum package_name
Example:
shell> md5sum mysql-standard-5.1.7-beta-linux-i686.tar.gz
aaab65abbec64d5e907dcd41b8699945 mysql-standard-5.1.7-beta-linux-i686.tar.gz
You should verify that the resulting checksum (the string of
hexadecimal digits) matches the one displayed on the download
page immediately below the respective package.
Note: Make sure to verify the
checksum of the archive file (for
example, the .zip or
.tar.gz file) and not of the files that are
contained inside of the archive.
Note that not all operating systems support the
md5sum command. On some, it is simply
called md5, and others do not ship it at
all. On Linux, it is part of the GNU
Text Utilities package, which is available for a
wide range of platforms. You can download the source code from
https://www.gnu.org/software/textutils/ as well.
If you have OpenSSL installed, you can use the command
openssl md5
package_name instead. A
Windows implementation of the md5 command
line utility is available from
https://www.fourmilab.ch/md5/.
winMd5Sum is a graphical MD5 checking tool
that can be obtained from
