Fresh Installation with Status and Access Issues
I just installed Ubuntu 24.04.1 LTS on a Dell 5820 workstation with IP
address 192.168.1.250. The OS seems to be working just fine. Now I'm trying
to get Apache solr installed and working. This is the version of Java I'm
running:
$ java --version
openjdk 21.0.4 2024-07-16
OpenJDK Runtime Environment (build 21.0.4+7-Ubuntu-1ubuntu224.04)
OpenJDK 64-Bit Server VM (build 21.0.4+7-Ubuntu-1ubuntu224.04, mixed mode,
sharing)
I installed solr version 9.7.0. The installation went fine. I can start the
solr service. Here's the status after it starts:
$ sudo systemctl status solr
● solr.service - LSB: Controls Apache Solr as a Service
Loaded: loaded (/etc/init.d/solr; generated)
Active: active (exited) since Sat 2024-10-26 18:27:30 EDT; 14min ago
Docs: man:systemd-sysv-generator(8)
Process: 16940 ExecStart=/etc/init.d/solr start (code=exited,
status=0/SUCCESS)
CPU: 24ms
Oct 26 18:27:28 myhost systemd[1]: Starting solr.service - LSB: Controls
Apache Solr as a Service...
Oct 26 18:27:28 myhost su[16944]: (to solr) root on none
Oct 26 18:27:28 myhost su[16944]: pam_unix(su-l:session): session opened for
user solr(uid=106) by (uid=0)
Oct 26 18:27:30 myhost solr[17008]: Started Solr server on port 8983
(pid=17001). Happy searching!
Oct 26 18:27:30 myhost systemd[1]: Started solr.service - LSB: Controls
Apache Solr as a Service.
Note "Active: active (exited)". I've added a firewall rule to open port
tcp/8983; here's the output from iptables:
ACCEPT 6 -- 127.0.0.1 0.0.0.0/0 tcp dpt:8983
ACCEPT 6 -- 192.168.1.46 0.0.0.0/0 tcp dpt:8983
Attempts to connect to the server using a browser with URL http://192.168.1.
250:8983/ time out. The connection attempt is being refused according to
iptables:
2024-10-26T18:53:51.741381-04:00 localhost kernel: iptables denied: IN=eno1
OUT= MAC=54:bf:64:94:de:a8:d8:bb:c1:94:72:25:08:00 SRC=192.168.1.46 DST=192.

DPT=8983 WINDOW=64240 RES=0x00 SYN URGP=0
Can someone please help me understand what's going on here? Why is the
service not in an active (running) state? Why is iptables blocking the
connection request when the port is open?
Thank you,
Scott

Oh, I agree. I'm still trying to figure out what's going on with iptables.
In the meantime, I tried using wget ("wget localhost:8983") to talk to my local instance. It successfully returned a solr admin HTML response, which says "Connection to Solr lost". I suspect that has something to do with the status I see when I run "systemctl status solr", which is "active (exited)". What might cause that? I don't see anything obvious in any of the solr log files.

The log "iptables denied" is the clear reason why you are unable to
connect.
Maybe this IPtable rules doesn't have the right priority and some other
rule at higher priority is blocking the traffic.

Why enable it? I've already noted that tcp/8983 is enabled using iptables. With ufw disabled it's not blocking anything.

Hi you have probably ufw (ubuntu integrated firewall) activated blocking port 8983.
You have to open that port on firewall

Hi you have probably ufw (ubuntu integrated firewall) activated blocking
port 8983.
You have to open that port on firewall

RE: Fresh Installation with Status and Access Issues

Thanks for that reminder - I now have access!
I'm still not sure of what's going on with iptables, though. I added an
ACCEPT rule for traffic from my remote machine to the beginning of the
chain, and that got rid of the blocking problem. I'll finish debugging that
later with TRACE rules.

Hi,
Solr by default binds only to localhost, as you have confirmed. See
https://solr.apache.org/guide/solr/latest/deployment-guide/taking-solr-to-pr
oduction.html#security-considerations
So please set SOLR_JETTY_HOST="0.0.0.0" to allow access from other hosts.

AFAIK the Solr server by default can only be contacted via localhost
access, i.e. http://127.0.0.1:8983.
If you want to change that, you have to adopt your configuration by
changing SOLR_IP_ALLOWLIST in your solr.in.sh configuration file, for
example
SOLR_IP_ALLOWLIST="127.0.0.1, 10.192.0.0/16, [::1]"

access, i.e. http://127.0.0.1:8983.
If you want to change that, you have to adopt your configuration by
changing SOLR_IP_ALLOWLIST in your solr.in.sh configuration file, for
example
SOLR_IP_ALLOWLIST="127.0.0.1, 10.192.0.0/16, [::1]"
