You’d want to stop apache and probably the locally running MTA. For me
that would be:

/etc/init.d/httpd stop
/etc/init.d/postfix stop

However we backup rt including the SQL databases every night with no
problems. RT is a tad unresponsive at times, maybe some table locks
thrown in which trouble the night time NOC team, but generally it backs
up fine.

Talking from the view point of having had to have done 3 restores this
year alone due to a mountain of fault Maxtor HDDs.

Cheers

Mat

it is importante to stop MTA before httpd. We are planning to configure a
replica of the database that will be used to generate backups, while
main copy continues running.

We use this procedure:

Cron:
36 5,11,16,21 * * * /var/lib/mysql/dumprt3.sh

dumprt3.sh
/sbin/service exim stop
/sbin/service httpd stop
mysqldump -u backup rt3 > /backup/local/rt3-$M.sql
mv -f /backup/amanda/rt3-2.sql.gz /backup/amanda/rt3-3.sql.gz
mv -f /backup/amanda/rt3-1.sql.gz /backup/amanda/rt3-2.sql.gz
mv -f /backup/amanda/rt3-atual.sql.gz /backup/amanda/rt3-1.sql.gz
/sbin/service httpd start
gzip /backup/local/rt3-$M.sql
/sbin/service exim start
cp /backup/local/rt3-$M.sql.gz /backup/amanda/rt3-atual.sql.gz
find /backup/local/rt3*.sql.gz -mtime +10 -delete

I’m not a MySQL expert by any means, but isn’t it possible to get a
quiescent backup of MySQL without stopping/starting any services?

It’s my understanding that one can issue a “read lock” as part of the
mysqldump command. If this is the case, wouldn’t it be less disruptive to
users since the web and email services would not be shutdown in order to
perform a backup.

I have also read that this “read lock” works particularly well when using it
to backup a replica, since this would require zero down time.

@Thomas

Thnx Thomas for advice , but at the moment we dont need an E-Mail Service so
it doesn’t matter if the service will be shutdown for backup process or not.

furthermore… Better safe than sorry :slight_smile:

Hello guys,

Sorry for the noob question on this thread.

I just need hint on running the RT.

After finishing the installation I used the command below to run the RT (don’t if it the right approach).

/opt/rt5/sbin/rt-server

And because my ssh session entered a disconnected state rt-server is running in background.

Now I need to stop it because I’ve made some changes in the configuration file. Do I kill the job or is there a better way to start and stop the service?

Any help is more than appreciated.

Regards

Killing the process is fine, when you get a web server Apache/nginx you can just stop those services instead of killing something
