LDAP with auth_pam and PHP to authenticate against MySQL

In the quest to secure MySQL as well as ease the number of complicated passwords to remember, many organizations are looking into external authentication, especially using LDAP. For free and open source, Percona’s PAM authentication plugin is the standard option.

tl;dr is I go through how to compile php-cli for use with auth_pam plugin.

Background
There are two plugins that can be used. From the documentation, the two plugins are:

  • Full PAM plugin called auth_pam. This plugin uses dialog.so. It fully supports the PAM protocol with arbitrary communication between client and server.
  • Oracle-compatible PAM called auth_pam_compat. …

More Details about InnoDB Compression Levels (innodb_compression_level)

In one of my previous posts, I shared InnoDB table compression statistics for a read-only dataset using the default value of innodb_compression_level (6).  In it, I claimed, without giving much detail, that using the maximum value for the compression level (9) would not make a big difference.  In this post, I will share more details about this claim.

TL;DR: tuning innodb_compression_level is not

Learning MySQL 5.7: Q & A

In this post I’ll answer questions I received in my Wednesday, July 19, 2017, webinar Learning MySQL 5.7!

First, thank you all who attended the webinar. The link to the slides and the webinar recording can be found here.

I received a number of interesting questions in the webinar that I’ve followed up with below.

Would there be a big difference on passing from 5.1 to 5.6 before going to 5.7 or, at this point, would it be roughly the same?

The biggest risk of jumping between versions, in this case 5.1 to 5.6, is reverting in case of problems. Rollbacks don’t happen often, but they do happen and you have to make …

Handy JSON to MySQL Loading Script

JSON in Flat File to MySQL DatabaseSo how do you load that JSON data file into MySQL. Recently I had this question presented to me and I thought I would share a handy script I use to do such work. For this example I will use the US Zip (postal) codes from JSONAR. Download and unzip the file. The data file is named zips.json and it can not be bread directly into MySQL using the SOURCE command. It needs to have the information wrapped in a more palatable fashion.

head zips.json 
{ "city" : "AGAWAM", "loc" : [ -72.622739, 42.070206 ], "pop" : 15338, "state" : "MA", "_id" : "01001" }
{ "city" : "CUSHMAN", "loc" : [ -72.51564999999999, 42.377017 ], "pop" : 36963, "state" : "MA", "_id" : "01002" }
{ "city" : "BARRE", "loc" : [ -72.10835400000001, 42.409698 ], "pop" : 4546, "state" : "MA", "_id" : "01005" }

This Week in Data: Thoughts from Percona Chief Evangelist Colin Charles

Welcome to a new weekly column on the Percona blog. My name is Colin Charles, Percona Chief Evangelist, and I have been involved in MySQL, MariaDB Server and the open source community for over a decade. Now I am at Percona, and this is my weekly column.

When you start a column, you have ask yourself what you’ll be writing about. Keeping the focus on the reader is what’s crucial. With this in mind, I plan to cover happenings, pointers and maybe even musings in this column. It’s August, and while many are away on summer vacations, there’s still plenty happening in the database world. So maybe this will be a little like the now-defunct, Weekly MySQL News. It will be broader than just MySQL, however, and focus on open source databases (after all, Percona’s mission is to …

Why we still need MyISAM (for read-only tables)

TL;DR: we still need MyISAM and myisampack because it uses less space on disk (half of compressed InnoDB) !

In the previous post, I shared my experience with InnoDB table compression on a read-only dataset.  In it, I claimed, without giving much detail, that using MyISAM and myisampack would result is a more compact storage on disk.  In this post, I will share more details about this claim.
