MariaDB-Galera-server RPM Upgrade issue in Cent OS 7.3

bms I tried to do an upgrade from 5.5.53 to 5.5.54 and it worked ok.
Could you share some specific commands that you are trying out?
Like, commands you are trying to start, stop or bootstrap the server?

Nirbhaya,
For starting first node I am using following command
/etc/init.d/mysql bootstrap
Sample output is shown below.

bms Could you try and share the output:

bms Do you have error log enabled? Can you share the last few lines from it that might relate to the bootstrap failure? Or lines from syslog (in case error log is not enabled).
You could also run :
sudo /etc/init.d/mysql bootstrap --log-error=/tmp/bootstrap.err
and share /tmp/bootstrap.err file.

I have run the command as advised. No file named /tmp/bootstrap.err created. Please see the output.

[root@dbc3 ~]# sudo /etc/init.d/mysql bootstrap --log-error=/tmp/bootstrap.err
Bootstrapping the cluster.. Starting MySQL. ERROR!
[root@dbc3 ~]# ls -l /tmp/bootstrap.err
ls: cannot access /tmp/bootstrap.err: No such file or directory
[root@dbc3 ~]#

elenst Any idea why error log isn't getting created in this case?
I found and fixed an issue after 5.5.54-galera release :
https://github.com/MariaDB/server/commit/ec9a48112b3caac39fb133d524f499172942d43a
Could this issue be related to the above fix?

nirbhay_c,

SELinux would be my first guess, Enforcing in particular. If it's set to Enforcing, try to change to Permissive and repeat.

bms Could you check if SELinux is causing the problem?

There are some selinux notes here: https://mariadb.com/kb/en/mariadb/what-to-do-if-mariadb-doesnt-start/

unrelated - https://mariadb.com/kb/en/mariadb/what-is-mariadb-55/ - 5.5 support ends in 2 and a bit months.

Dear Nirbhay, Daniel Black,

Yes, Problem was due to SELinux. See the execution output below.
======================
[root@dbc3 ~]# getenforce
Enforcing
[root@dbc3 ~]# setenforce 0
[root@dbc3 ~]# /etc/init.d/mysql bootstrap
Bootstrapping the cluster.. Starting MySQL.170127 09:26:45 mysqld_safe Logging to '/var/lib/mysql/dbc3.err'.
170127 09:26:45 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
... SUCCESS!
[root@dbc3 ~]# getenforce
Permissive
[root@dbc3 ~]#
====================

What next? I want SELinux in enforcing mode.

See the previously mentioned URL. https://github.com/MariaDB/server/tree/5.5-galera/policy/selinux and https://blogs.oracle.com/jsmyth/entry/selinux_and_mysql provide guides on getting selinux back into enforcing mode.

https://mariadb.com/kb/en/mariadb/what-to-do-if-mariadb-doesnt-start/ can be edited by you if you see ways it can be improved.
