Elasticsearch Install specific version

[sinichi19]

Good Day,

I want to try to fresh install the new zammad 3.2 but i saw that the 3.2 as of now is not compatible for elasticsearch 7.5. my question is how can I install elasticsearch 7.4.2 version because when i used the installation for ubuntu 18.04 is already direct to install the 7.5

Thank You.

here solution for Centos, may be you can adapt it for Ubuntu:

#install elasticsearch version 7.4.x (latest, but not 7.5)
yum install -y java-1.8.0-openjdk elasticsearch-0:7.4.2-1.x86_64
#install plugin for elasticsearch
sudo /usr/share/elasticsearch/bin/elasticsearch-plugin install ingest-attachment
systemctl start elasticsearch
systemctl enable elasticsearch
sysctl -w vm.max_map_count=262144
#install versionlock for yum and lock elasticsearch from updates!!!
yum -y install yum-versionlock
yum versionlock add elasticsearch
yum versionlock list elasticsearch

it seems, what problem fixed already: #2824 - Elasticsearch 7.5.x support.

Starting with this build:
zammad-0:3.2.0-1575457512.de2e8f4b.centos7.x86_64

Yeah but be aware, something seems to be different with 7.5

Did you reload the page or change to e.g. Groups and Back to User? Should work just fine. If not, please ensure that there are no errors in your production log. Oh… and maybe use the template that you removed to provide further information. * Used Zammad version: * Used Zammad installation source: (source, package, ...) * Operating system: * Browser + version: ### Expected behavior: * ### Actual behavior: * ### Steps to reproduce the behavior: *

centos 7, zammad 3.2.0 from package, elasticsearch 7.4.2
updated elasticsearch to 7.5.0, elasticsearch not running after update.
found what ingest-attachment need to be reinstalled.
zammad run rake searchindex:rebuild
looks like no problem. users are present in system. but i did not fully test helpdesk.
