Upgrading Logstash

The process to upgrade minor releases of LogStash is quite simple — stop service, drop the binaries in place, and start service. In this case, my upgrade process is slightly complicated by the fact our binaries aren’t installed to the “normal” location from the RPM. I am upgrading from 7.7.0 => 7.17.4

The first step is, obviously, to download the LogStash release you want – in this case, it is 7.17.4 as upgrading across major releases is not supported.

 

cd /tmp
mkdir logstash
mv logstash-7.17.4-x86_64.rpm ./logstash

cd /tmp/logstash
rpm2cpio logstash-7.17.4-x86_64.rpm | cpio -idmv

systemctl stop logstash
mv /opt/elk/logstash /opt/elk/logstash-7.7.0
mv /tmp/logstash/usr/share/logstash /opt/elk/
mkdir /var/log/logstash
mkdir /var/lib/logstash

mv /tmp/logstash/etc/logstash /etc/logstash
cd /etc/logstash
mkdir rpmnew
mv jvm.options ./rpmnew/
mv log* ./rpmnew/
mv pipelines.yml ./rpmnew/
mv startup.options ./rpmnew/
cp -r /opt/elk/logstash-7.7.0/config/* ./

ln -s /opt/elk/logstash /usr/share/logstash
ln -s /etc/logstash /opt/elk/logstash/config

chown -R elasticsearch:elasticsearch /opt/elk/logstash
chown -R elasticsearch:elasticsearch /var/log/logstash
chown -R elasticsearch:elasticsearch /var/lib/logstash
chown -R elasticsearch:elasticsearch /etc/logstash

systemctl start logstash
systemctl status logstash
/opt/elk/logstash/bin/logstash --version
