Elasticsearch 1.4.4 Setup Problem

ali.q · December 10, 2016, 3:30pm

Hi all,

I'm totally new here, so please forgive me if I'm posing in the wrong category or ask a newbie question.

I've setup Elasticsearch 1.4.4 for a SugarCRM system and I'm not quite sure if it is working fine or not. The status of Elasticsearch is ambiguous. When running:

systemctl status elasticsearch.service -l

I get the following output:

elasticsearch.service - Starts and stops a single elasticsearch instance on this system
   Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled)

Now, while it says that the service is running, it also says that it has entered a failed state and elasticsearch.pid not readable (yet?) after start.

I'm not sure if this is normal. I've made a lot of Googling but couldn't find a definite answer.

I'm using CentOS 7

Really appreciate your input and sorry if the question is duplicate or something.
Thanks!

Have a look in /var/log/elasticsearch/ for more logging info.

Hi @warkolm

I'm still concerned about the "elasticsearch.pid not readable (yet?) after start" message.

FYI: When I run curl -X GET 'http://localhost:9200' I get the following reponse which looks fine:

{
"status" : 200,
"name" : "Thunderclap",
"cluster_name" : "sugarcrm",
"version" : {
"number" : "1.4.4",
"build_hash" : "c88f77ffc81301dfa9dfd81ca2232f09588bd512",
"build_timestamp" : "2015-02-19T13:05:36Z",
"build_snapshot" : false,
"lucene_version" : "4.10.3"
},
"tagline" : "You Know, for Search"
}

Any input or help is much appreciated.
Thanks!

Everything looks ok, other than that PID issue, but it doesn't seem to be causing major issues.

ali.q · December 13, 2016, 6:46am

Thanks for your response @warkolm

Is there a way I can make sure the PID message is totally normal?
How can I correct it? Or isn't that necessary at all?

Thanks again!

jprante · December 13, 2016, 12:28pm

See https://github.com/elastic/elasticsearch/issues/11594 for the /var/run/elasticsearch/elasticsearch.pid issue.

ali.q · December 13, 2016, 12:55pm

Thanks @jprante

I'm using elasticsearch 1.4.4 (I need to use it since it is a requirement for SugarCRM 7.7)

When running ls -al /var/run/elasticsearch I get the following:

drwxr-xr-x  2 elasticsearch elasticsearch   60 Dec 13 11:50 .
drwxr-xr-x 38 root          root          1200 Dec 13 11:52 ..
-rw-r--r--  1 elasticsearch elasticsearch    3 Dec 13 11:50 elasticsearch.pid

So, the folder and file both belong to elasticsearch. I don't know if the rights are enough?
Looking at the page you pointed to I see that this issue was introduced in version 1.6.

I'm concerned about the Dec 12 08:50:02 localhost.localdomain systemd[1]: PID file /var/run/elasticsearch/elasticsearch.pid not readable (yet?) after start. message that I get when I run a systemctl status elasticsearch -l

I'm not sure whether this is normal? I'm facing a lot of issues with SugarCRM and want to make sure elastic is working fine.

When I do a curl -X GET 'http://localhost:9200' I get the standard response:
{
"status" : 200,
"name" : "SugarCRM Node",
"cluster_name" : "sugarcrm",
"version" : {
"number" : "1.4.4",
"build_hash" : "c88f77ffc81301dfa9dfd81ca2232f09588bd512",
"build_timestamp" : "2015-02-19T13:05:36Z",
"build_snapshot" : false,
"lucene_version" : "4.10.3"
},
"tagline" : "You Know, for Search"
}

Is there a way to make sure elastic is 100 percent functional and not making any issues?
How can I make sure that the pid not readable message isn't causing any problems.

Thanks a lot!

jprante · December 13, 2016, 2:22pm

As @warkolm said, the PID issue is just a glitch, it does not influence Elastiscearch. It is a warning message by the systemctl start script, not by Elastcsearch. In the answers of https://github.com/elastic/elasticsearch/issues/11594 you can learn how to change /var/run/elasticsearch/elasticsearch.pid into /var/run/elasticsearch.pid in the systemctl script. This will make the warning disappear.

ali.q · December 13, 2016, 2:45pm

Thanks a lot @jprante & @warkolm

You saved my day. Now, I'm at least sure about elastic and can look elsewhere!

Have a nice day and thanks again
