RE: Multiple Tomcat Instances on Linux Box : Binding exceptions galore : No ideas left
does tomcat bind to a particular port which is hardcoded in? Has anyone run multiple instances of tomcat on one machine or is it assumed that tomcat is run from client machines and not on a central server? If so,it seems to be a bit strange. Appreciate any help. Bert. Hi folks. I'm trying to setup tomcat on one of our servers so that multiple developers can have their own tomcat instance, but keep running into bind exceptions. I've been fiddling with it for quite a few days but have come to a stage where I can't figure out what more to do. ___ Here is the setup: We use redhat linux 7.2, tomcat rpm 4.0.3-1, j2sdk-1.4.0. Tomcat has been installed in /var/tomcat4 on the server. For each developer I have set CATALINA_BASE to point to their own tomcat directory ( /home/www/user/tomcat ) which contains the conf/webapps/temp/logs directories. I have modified the server.xml file in each users directory to use unassigned ports ( eg ports 9620 to 9629 for user1, 9630 to 9639 for user2 etc...). There are no other services running using any of these ports. The server is assigned a whole heap of IP addresses, so IPs 192.168.1.253-240, for instance, all point to the same physical machine. All ip addesses resolve to a name. ie 192.168.1.253=user1.domain.cxm, 192.168.1.252=user2.domain.cxm etc... DNS works fine. These names are used in each users server.xml file (for engine and hosts). No two server.xml files share the same hostname. Tomcat is started by calling '/usr/bin/tomcat4 start' This script has been modified to run the '/usr/bin/dtomcat4' script as the user making the call. Now, to start each instance, each user telnets into the server and executes the command '/usr/bin/tomcat4 start'. The directories tomcat uses are all correct (it does use the correct CATALINA_BASE). _ The problem is this: Tomcat runs for each user if no other tomcat instance is running (I ensure that by running gtop on the server and killing instances run by other users). However, if one other instance of tomcat is running (by another user), we get the error message below. I have tried commenting out all the connectors except for non-SSL HTTP/1.1. I have turned them all on and generated keystore files for SSL. I have replaced the hostnames with the IP addresses. Nothing seems to work. I am at a complete loss at what to do. If anybody has ANY idea where to go from here, I am open to suggestions. _ error message is: Catalina.start: LifecycleException: Error creating server socket (java.net.BindException): java.net.BindException: Address already in use LifecycleException: Error creating server socket (java.net.BindException): java.net.BindException: Address already in use at org.apache.catalina.connector.warp.WarpConnector.initialize(WarpCo nnector.ja va:491) at org.apache.catalina.core.StandardService.initialize(StandardServic e.java:454 ) at org.apache.catalina.core.StandardServer.initialize(StandardServer. java:553) at org.apache.catalina.startup.Catalina.start(Catalina.java:780) at org.apache.catalina.startup.Catalina.execute(Catalina.java:681) at org.apache.catalina.startup.Catalina.process(Catalina.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorIm pl.java:39 ) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAc cessorImpl .java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:243) - Root Cause - java.net.BindException: Address already in use at java.net.PlainSocketImpl.socketBind(Native Method) at java.net.PlainSocketImpl.bind(PlainSocketImpl.java:321) at java.net.ServerSocket.bind(ServerSocket.java:308) at java.net.ServerSocket.bind(ServerSocket.java:266) at java.net.ServerSocket.init(ServerSocket.java:182) at java.net.ServerSocket.init(ServerSocket.java:138) at org.apache.catalina.net.DefaultServerSocketFactory.createSocket(De faultServe rSocketFactory.java:118) at org.apache.catalina.connector.warp.WarpConnector.initialize(WarpCo nnector.ja va:485) at org.apache.catalina.core.StandardService.initialize(StandardServic e.java:454 ) at org.apache.catalina.core.StandardServer.initialize(StandardServer. java:553) at org.apache.catalina.startup.Catalina.start(Catalina.java:780) at org.apache.catalina.startup.Catalina.execute(Catalina.java:681) at org.apache.catalina.startup.Catalina.process(Catalina.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorIm pl.java:39 ) at

I have modified the server.xml file in each users directory to use unassigned ports ( eg ports 9620 to 9629 for user1, 9630 to 9639 for user2 etc...). There are no other services running using any of these ports. The server is assigned a whole heap of IP addresses, so IPs 192.168.1.253-240, for instance, all point to the same physical machine. All ip addesses resolve to a name. ie 192.168.1.253=user1.domain.cxm, 192.168.1.252=user2.domain.cxm etc... DNS works fine. These names are used in each users server.xml file (for engine and hosts). No two server.xml files share the same hostname. Tomcat is started by calling '/usr/bin/tomcat4 start' This script has been modified to run the '/usr/bin/dtomcat4' script as the user making the call. Now, to start each instance, each user telnets into the server and executes the command '/usr/bin/tomcat4 start'. The directories tomcat uses are all correct (it does use the correct CATALINA_BASE). _ The problem is this: Tomcat runs for each user if no other tomcat instance is running (I ensure that by running gtop on the server and killing instances run by other users). However, if one other instance of tomcat is running (by another user), we get the error message below. I have tried commenting out all the connectors except for non-SSL HTTP/1.1. I have turned them all on and generated keystore files for SSL. I have replaced the hostnames with the IP addresses. Nothing seems to work. I am at a complete loss at what to do. If anybody has ANY idea where to go from here, I am open to suggestions. _ error message is: Catalina.start: LifecycleException: Error creating server socket (java.net.BindException): java.net.BindException: Address already in use LifecycleException: Error creating server socket (java.net.BindException): java.net.BindException: Address already in use at org.apache.catalina.connector.warp.WarpConnector.initialize(WarpCo nnector.ja va:491) at org.apache.catalina.core.StandardService.initialize(StandardServic e.java:454 ) at org.apache.catalina.core.StandardServer.initialize(StandardServer. java:553) at org.apache.catalina.startup.Catalina.start(Catalina.java:780) at org.apache.catalina.startup.Catalina.execute(Catalina.java:681) at org.apache.catalina.startup.Catalina.process(Catalina.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorIm pl.java:39 ) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAc cessorImpl .java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:243) - Root Cause - java.net.BindException: Address already in use at java.net.PlainSocketImpl.socketBind(Native Method) at java.net.PlainSocketImpl.bind(PlainSocketImpl.java:321) at java.net.ServerSocket.bind(ServerSocket.java:308) at java.net.ServerSocket.bind(ServerSocket.java:266) at java.net.ServerSocket.init(ServerSocket.java:182) at java.net.ServerSocket.init(ServerSocket.java:138) at org.apache.catalina.net.DefaultServerSocketFactory.createSocket(De faultServe rSocketFactory.java:118) at org.apache.catalina.connector.warp.WarpConnector.initialize(WarpCo nnector.ja va:485) at org.apache.catalina.core.StandardService.initialize(StandardServic e.java
