[SOLVED] multiple instances of tomcat6

Habitual · 06-26-2014, 03:22 PM

So, I installed tomcat6 from yum repo on CentOS 6.5.
I used How to Run Multiple Instances of Tomcat on a Single Server which gets me most of the way there.

I created /srv/tomcat/tomcat[12] directories and ran a

Code:

for i in tomcat1 tomcat2 ; do mkdir -p /srv/tomcat/${i}/logs \
&& mkdir /srv/tomcat/${i}/webapps && mkdir /srv/tomcat/${i}/work \
&& mkdir /srv/tomcat/${i}/temp && cp -R /usr/share/tomcat6/conf/ \
/srv/tomcat/${i} ; done

I then did a

Code:

cp /etc/sysconfig/tomcat6 /etc/sysconfig/tomcat1
cp /etc/sysconfig/tomcat6 /etc/sysconfig/tomcat2
cp /etc/init.d/tomcat6 /etc/init.d/tomcat1
cp /etc/init.d/tomcat6 /etc/init.d/tomcat2

This was a little different that what How to Run Multiple Instances of Tomcat on a Single Server said to (it shows creating symlinks).

I then edited /etc/sysconfig/tomcat[12] accordingly (tomcat[12])

Code:

CATALINA_BASE="/srv/tomcat/tomcat1" 
CATALINA_PID="/var/run/tomcat1.pid" 
TOMCAT_LOG="/srv/tomcat/tomcat1/logs/catalina.out" 
CONNECTOR_PORT="8080"

service tomcat1 and tomcat2 both seem to be working and I have ports open says

Code:

netstat -plaunt | grep java
tcp        0      0 ::ffff:127.0.0.1:9005       :::*                        LISTEN      16820/java          
tcp        0      0 :::8080                     :::*                        LISTEN      17027/java          
tcp        0      0 :::9009                     :::*                        LISTEN      16820/java          
tcp        0      0 :::9090                     :::*                        LISTEN      16820/java          
tcp        0      0 ::ffff:127.0.0.1:8005       :::*                        LISTEN      17027/java          
tcp        0      0 :::8009                     :::*                        LISTEN      17027/java

It all looks right.

It is here that I think I have an issue:
I can't do a lynx http://localhost:8080 or http://127.0.0.1:8080
both give me a "Alert!: HTTP/1.1 400 Bad Request"
I believe I should be seeing a Tomcat 'homepage'?

Curious is they are both using the same tomcat6.conf in

Code:

/etc/init.d/tomcat1:TOMCAT_CFG="/etc/tomcat6/tomcat6.conf"
/etc/init.d/tomcat2:TOMCAT_CFG="/etc/tomcat6/tomcat6.conf"

So I copied /etc/tomcat6/tomcat6.conf to /etc/tomcat6/tomcat[12].conf
and edited

Code:

/etc/init.d/tomcat1:48:TOMCAT_CFG="/etc/tomcat6/tomcat1.conf"
/etc/init.d/tomcat2:48:TOMCAT_CFG="/etc/tomcat6/tomcat2.conf"

making the the same changes in each that I made in /etc/sysconfig/tomcat[12] specified at How to Run Multiple Instances of Tomcat on a Single Server

netstat shows the ports open but still lynx fails with the same message.

The goal here is to install 2 instances of apache's solr 4.8.1. One under each tomcat instance.

I'd appreciate some assistance.

Thanks for your valuable time.

Hi Habitual,

Thanks for the link, btw. Good stuff.

Is anything getting written to your respective log files? Particularly the second instances log? Have you tried a curl or wget to the :8005 and :9005 ? Perhaps the url response would give us a clue.

Oh yes.

tomcat2's catalina.out
I fixed the first 3 lines with a

Code:

chown -R tomcat. /srv/tomcat/

I shutdown tomcat2 and did an

Code:

echo "" > /srv/tomcat/tomcat2/logs/catalina.out

and started it.

Code:

cat /srv/tomcat/tomcat2/logs/catalina.out

I don't know how to use curl except to grab stuff, but I tried these:

Code:

curl localhost:8005
curl: (56) Failure when receiving data from the peer
curl localhost:9005
curl: (56) Failure when receiving data from the peer

Hopefully, that will help you help me.

Thanks.

That should work.

I'm thinking that the server is listening on 9009...
Do me a favor and check 9009 also are you running any kind of firewall locally?

Habitual · 06-27-2014, 08:42 AM

Code:

curl localhost:8005
curl: (56) Failure when receiving data from the peer

curl localhost:9009
curl: (52) Empty reply from server

and

Code:

iptables -nL
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

Thanks.

dijetlo:

Thanks for the help.
This is resolved.

Code:

yum install tomcat6-webapps
cp -R /usr/share/tomcat6/webapps/ /srv/tomcat/tomcat1
cp -R /usr/share/tomcat6/webapps/ /srv/tomcat/tomcat2
chown -R tomcat. /srv/tomcat/
service tomcat1 restart
service tomcat2 restart
