Package: munin-node Version: 2.0.49-1 Severity: normal Tags: patch --- Please enter the report below this line. ---
Dear maintainer, I recently upgraded to Buster, all was working fine or at least that was thinking, on all our production machines have found an unusual amount of warnings on /var/log/syslog: Access denied for user 'root'@'localhost' (using password: YES) Searching the origin of this messagesi, finded that munin was the culprit, so searching for similar errors found bug #864845 when the solution was to change: -env.mysqluser debian-sys-maint +env.mysqluser root And looks like the default configuration for munin-node now is that one, the oposite has worked for me, returning to debian-sys-maint to handle the request of munin, my machines are running mariadb-server (10.3.15-1) with mysql_secure_installation, password set for root and no test db. My current fix is: diff -u /home/vicm3/1/etc/munin/plugin-conf.d/munin-node /etc/munin/plugin-conf.d/munin-node --- /home/vicm3/1/etc/munin/plugin-conf.d/munin-node 2019-05-15 18:21:08.000000000 -0500 +++ /etc/munin/plugin-conf.d/munin-node 2019-08-14 11:27:37.234767719 -0500 @@ -73,7 +73,7 @@ [mysql*] user root env.mysqlopts --defaults-file=/etc/mysql/debian.cnf -env.mysqluser root +env.mysqluser debian-sys-maint env.mysqlconnection DBI:mysql:mysql;mysql_read_default_file=/etc/mysql/debian.cnf [postfix_mailqueue] Please check and if it's useful commit.
