mysqld not running after upgrade from 15.8 -to 16.3

Post by biera16 » Thu Dec 01, 2016 1:53 am


I started off with a Linux install running perfectly fine on 12.1.
Since it was such an old installation I decided to patch it according to ... 9127#p9127 which mentions the 12.1 -> 15.5 -> 15.8 -> 16.3 -> 16.11 migration path. I got as far as upgrading
12.1 -> 15.5
15.5 -> 15.8
But after I upgraded 15.8 to 16.3 the mysql stopped working. I am no expert but it appears the mysql server is no longer running.

Code: Select all

[root@scrutinizer ~]# /home/plixer/scrutinizer/bin/scrut_util.exe -update_plixerini_mysqlroot

scrut_util (2016-03-22 18:52:31 -0400 (Tue, 22 Mar 2016))

*** not tested on linux appliance ***

Update plixer.ini db root password

Note: This command will not change the database root password. If you wish to
change the password, execute scrut_util.exe -reset_mysql_password

The Plixer Database Service is currently not running. Please start the
service and re-run this command.

Code: Select all

[root@scrutinizer ~]# ps aux | grep -i sql
root      3116  0.0  0.0 103312   912 pts/1    S+   01:49   0:00 grep -i sql
[root@scrutinizer ~]#
Looks like mysql has been removed?

Code: Select all

[root@scrutinizer ~]# chkconfig | grep -i sql

How do I verify this?

best regards

Hello Arne,

It sounds like the MariaDB service did not kick off after installing 16.3. Try running 'service plixer_db start' on the command line.

If this does not solve you issue please reply to this post with the last 50 lines of your install log found here:

Hello Arne,

These would be our suggested steps to follow if for some reason MariaDB fails to install on a 16.3 upgrade:

Setp one: Is mysql still there? (If not skip to Step three) If so...

Code: Select all

 yum -y remove mysql mysql-server mysql-libs mysql-community-release mysql-community-libs mysql-community-common
Step two: Run this command

Code: Select all

 rpm -e mysql-community-client mysql-community-server mysql-community-release mysql-community-common mysql-community-libs
Step three: This installs MariaDB

Code: Select all

 rpm -ivh --nodeps ~plixer/scrutinizer/files/linux/MariaDB-10.0.*
Step four:

Code: Select all

 rm -f /etc/my.cnf
Step five:

Code: Select all

 cp /etc/my_plixer.cnf /etc/my.cnf
Step six:

Code: Select all

 cp /etc/init.d/mysql /etc/init.d/mysqld
Step seven:

Code: Select all

 service mysql start
Step eight: Rerun the 16.3 installer ( ...

Hi Jenn

your instructions were 100% spot on. All working again. I finally upgraded to 16.11 !!!

Also figured out that pressing CTRL-F5 cures a lot of browser weirdness after an upgrade.

Code: Select all
