Package: munin-node
Version: 1.4.3-2
Severity: normal
Tags: + patch
I upgraded munin packages on several Lenny servers from 1.2.6 (Lenny) to
1.4.3 (Squeeze). I discovered the "old" mysql plugin note on the mysql
graphs and created the various plugin symlinks I wanted to use for the
new mysql plugin, while leaving the old mysql links intact, running both
old/new mysql plugins.
The the new /usr/share/munin/plugins/mysql_ plugin uses the DBD::Mysql
perl module (the old one uses mysqladmin), and testing out one of them
out, I got:
mshu...@bay:~$ sudo munin-run mysql_connections
DBI connect('mysql;mysql_connect_timeout=5','root',...) failed: Access
denied for user 'root'@'localhost' (using password: NO) at
/etc/munin/plugins/mysql_connections line 875
I added the following to [mysql*] in plugin-conf.d/munin-node:
env.mysqlconnection
DBI:mysql:mysql;mysql_read_default_file=/etc/mysql/debian.cnf
then received:
mshu...@bay:~$ sudo munin-run mysql_connections
DBI
connect('mysql;mysql_read_default_file=/etc/mysql/debian.cnf;mysql_connect_timeout=5','root',...)
failed: Access denied for user 'root'@'localhost' (using password: YES)
at /etc/munin/plugins/mysql_connections line 875
So the connection is still attempting user 'root' with the client
password of the debian-sys-maint user, which fails. One more env
addition that the new mysql plugin groks got me a successful run:
env.mysqluser debian-sys-maint
I am currently graphing both the old mysql and the new mysql2 graphs
successfully - the addition of the 2 lines to plugin-conf.d/munin-node
does not seem to interrupt the functionality of the old deprecated
plugin, if there are people that continue to use it. Some further
validation would be appreciated.
Patch attached.
