Thank you Paras:
If I am already user of root, and still run sudo? no, it doesn't work:
[root@pocnnr1n1 solr]# sudo bin/solr start -force
sudo: bin/solr: command not found
[root@pocnnr1n1 solr]# ls -l bin/solr
-rw-r--r-- 1 root root 80630 Jul 19 09:09 bin/solr
So, I followed your suggestion and added +x, now run the command again:
[root@pocnnr1n1 solr]# bin/solr start

WARNING: Starting Solr as the root user is a security risk and not
considered best practice. Exiting.
Please consult the Reference Guide. To override this check, start
with argument '-force'
alright, I'll add the -force option:
[root@pocnnr1n1 solr]# bin/solr start -force

Please check your -d parameter to set the correct Solr server directory.
BUT: the folder server is there, and no start.jar
