Hello Elasticsearch forum,

My name is Bogdan Oproescu and I am senior data architect for EasyDO Digital Technologies in Bucharest. I am writing you today, to report an issue with our initial Elasticsearch engine configuration failure this morning, on our Linux CentOS server version 8.1. Here is the error message below:

Step 1: install Elasticsearch:  
a. For CentOS we use rpm:  
curl -L -O [https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.8.1-x86\_64.rpm](https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-7.8.1-x86_64.rpm)  
b. sudo rpm -i elasticsearch-7.8.1-x86\_64.rpm  
2. There were dependency problems on our Linux server, with a previous version of Elastic installed on this server (now deprecated!):  
a. view previous versions of Elasticsearch installed:  
[root@ElasticEDT bin]# rpm -qa | grep elastic  
elasticsearch-7.6.1-1.x86\_64  
b. remove previous versions of Elasticsearch:  
[root@ElasticEDT bin]# rpm -e elasticsearch-7.6.1-1.x86\_64  
Stopping elasticsearch service... OK  
warning: file /etc/elasticsearch/log4j2.properties: remove failed: No such file or directory  
warning: /etc/elasticsearch/jvm.options saved as /etc/elasticsearch/jvm.options.rpmsave  
warning: file /etc/elasticsearch/elasticsearch.yml: remove failed: No such file or directory  
Deleting log directory... OK  
[root@ElasticEDT bin]#  
c. install the new version of Elasticsearch:  
sudo rpm -i elasticsearch-7.8.1-x86\_64.rpm  
--\> and the output is this:  
[root@ElasticEDT bin]# sudo rpm -i elasticsearch-7.8.1-x86\_64.rpm  
Creating elasticsearch group... OK  
Creating elasticsearch user... OK

### NOT starting on installation, please execute the following statements to configure elasticsearch service to start automatically using systemd

sudo systemctl daemon-reload  
sudo systemctl enable elasticsearch.service

### You can start elasticsearch service by executing

sudo systemctl start elasticsearch.service  
Created elasticsearch keystore in /etc/elasticsearch/elasticsearch.keystore  
[/usr/lib/tmpfiles.d/elasticsearch.conf:1] Line references path below legacy directory /var/run/, updating /var/run/elasticsearch → /run/elasticsearch; please update the tmpfiles.d/ drop-in file accordingly.  
[/usr/lib/tmpfiles.d/libgpod.conf:1] Line references path below legacy directory /var/run/, updating /var/run/libgpod → /run/libgpod; please update the tmpfiles.d/ drop-in file accordingly.  
[/usr/lib/tmpfiles.d/mdadm.conf:1] Line references path below legacy directory /var/run/, updating /var/run/mdadm → /run/mdadm; please update the tmpfiles.d/ drop-in file accordingly.  
[/usr/lib/tmpfiles.d/radvd.conf:1] Line references path below legacy directory /var/run/, updating /var/run/radvd → /run/radvd; please update the tmpfiles.d/ drop-in file accordingly.

[root@ElasticEDT bin]#  
3. Therefore our new version of Elasticsearch analytics engine was correctly installed on our ElasticEDT server!  
a. Now we try to start this new version of Elasticsearch:  
[root@ElasticEDT bin]# sudo service elasticsearch start  
Starting elasticsearch (via systemctl): Job for elasticsearch.service failed because the control process exited with error code.  
See "systemctl status elasticsearch.service" and "journalctl -xe" for details.  
[FAILED]  
b. To find out more, we can execute this command below:  
[root@ElasticEDT elasticsearch]# systemctl status elasticsearch.service  
● elasticsearch.service - Elasticsearch

Can you share the content of the file `/var/log/elasticsearch/elasticsearch.log`

Hi Yassine,  
Thanks for your prompt reply: I have checked earlier our CentOS 8.1 Linux Elastic server, and inside this folder /var/log/elasticsearch we only have these files below:

so which one of these would you like me to send you?

so it makes sense to send you the first 2 files above, as these seem to be periodically updated. Here you go:

1. [root@ElasticEDT elasticsearch]# more gc.log

I hope this helps, to clarify what the problem is, and why Elasticsearch analytics engine does not start for us!

Can you try runnung elasticsearch manually to see what happens ?  
Use this : `/usr/share/elasticsearch/bin/elasticsearch`

When your install RPM package, ES is installed in :

- /etc/elasticsearch (config file),
- /usr/share/elasticsearch (binaries)

hi Yassine,  
thanks for your reply earlier, and your explanation that ES is installed in:

- /etc/elasticsearch (config file),
- /usr/share/elasticsearch (binaries)  
I checked for myself and I'm happy to confirm this is so, the installation makes more sense to me now!

here is the error

</div>

so it looks like I cannot run Elasticsearch as root:  
org.elasticsearch.bootstrap.StartupException: java.lang.RuntimeException: can not run elasticsearch as root  
my question is: what user should I run it under, and why is this not stated in your online documentation below:

hi Yassine,  
thanks for your update, we both replied at the same time: please see my previous post below: which user should it run under?

hi Yassine,  
thanks for this, I did this and set the new password for the elasticsearch user.  
Now I am getting this error below:  
bash-4.4$ ./elasticsearch

I have fixed the obvious file and directory permissions errors above, but now I am getting another error, see below for more info:

hi Yassine,  
I have opened this nodes folder in the maximal possible way, 777:  
[root@ElasticEDT elasticsearch]# id  
uid=0(root) gid=0(root) groups=0(root) context=unconfined\_u:unconfined\_r:unconfined\_t:s0-s0:c0.c1023  
[root@ElasticEDT elasticsearch]# pwd  
/var/lib/elasticsearch  
[root@ElasticEDT elasticsearch]# ll  
total 0  
drwxrwsrwx. 3 elasticsearch elasticsearch 15 Mar 30 22:28 nodes  
[root@ElasticEDT elasticsearch]#  
and I also changed the owner to elasticsearch, as you can see, and yet the problem is still happening, see below:

No, there is no data below from the old installation:  
[root@ElasticEDT 0]# pwd  
/var/lib/elasticsearch/nodes/0  
[root@ElasticEDT 0]# ll  
total 0  
-rwxr-xr-x. 1 root root 0 Mar 30 22:28 node.lock  
drwxr-sr-x. 2 root root 121 Mar 31 13:47 \_state  
[root@ElasticEDT 0]#
