I have edited my post to make it look more clear.

I wanted to upgrade GeoServer from v.2.7.1 to v.2.10.1 on Ubunutu 14.4. I deployed v.2.7.1 in Tomcat Web Application Manager. I have downloaded v2.10.1, geoserver-2.10.1-war.zip and unzipped it in /var/lib/tomcat7/webapps/. Tomcat Web Application Manager is saying that geoserver is not running, http://myhostname:8080/geoserver/web returned HTTP Status 404.

server.xml in /var/lib/tomcat7/conf looks like:

<Connector port="8080" protocol="HTTP/1.1"
           connectionTimeout="20000"
           URIEncoding="UTF-8"
           redirectPort="8443" />

Then I have undeployed v.2.10.1 and deployed v.2.7.1 a-g-a-i-n in the same configuration and it worked fine.


Edit:

I figured out that v.2.10.1 needs java8 to run, and previously I had java 7 running with tomcat7. I have uninstalled both of them and then install new versions java version "1.8.0_111" and Apache Tomcat/8.0.39 (https://www.digitalocean.com/community/tutorials/how-to-install-apache-tomcat-8-on-ubuntu-14-04 where in tomcat.conf I changed line env JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/jre to env JAVA_HOME=/usr/lib/jvm/java-8-oracle/jre.

So now I have:

opt
├── gwc
├── java
└── tomcat

/opt/tomcat/webapps
├── docs
├── examples
├── geoserver
├── host-manager
├── manager
└── ROOT

Tomcat Web Application Manager says that GeoServer is running, however myhostname:8080/geoserver/web returned HTTP Status 404.

with catalina.sh run I get this:

To run GeoServer 2.10+ you must make sure that tomcat is running in a Java 8 JVM. To see if this is your issue check in /var/log/tomcat/localhost.2017-01-13/log (with today's date) and if you see anything that says Unsupported major.minor version 52.0 like:

On Ubuntu 14 I found that the init.d/tomcat7 script was hardcoded to look for Java 7 or 6. To fix this (after I had installed Java 8 and set it using the alternatives system) I edited (as root) /etc/init.d/tomcat7 and found the section that was setting JAVA_HOME:

# this is a work-around until there is a suitable runtime replacement 
# for dpkg-architecture for arch:all packages
# this function sets the variable OPENJDKS
find_openjdks()
{
        for jvmdir in /usr/lib/jvm/java-7-openjdk-*
        do
                if [ -d "${jvmdir}" -a "${jvmdir}" != "/usr/lib/jvm/java-7-openjdk-common" ]
                then
                        OPENJDKS=$jvmdir
                fi
        done
        for jvmdir in /usr/lib/jvm/java-6-openjdk-*
        do
                if [ -d "${jvmdir}" -a "${jvmdir}" != "/usr/lib/jvm/java-6-openjdk-common" ]
                then
                        OPENJDKS="${OPENJDKS} ${jvmdir}"
                fi
        done
}
# 
OPENJDKS=""
find_openjdks
# The first existing directory is used for JAVA_HOME (if JAVA_HOME is not
# defined in $DEFAULT)
JDK_DIRS="/usr/lib/jvm/default-java ${OPENJDKS} /usr/lib/jvm/java-6-openjdk /usr/lib/jvm/java-6-sun /usr/lib/jvm/java-7-oracle"

# Look for the right JVM to use
for jdir in $JDK_DIRS; do
    if [ -r "$jdir/bin/java" -a -z "${JAVA_HOME}" ]; then
      JAVA_HOME="$jdir"
    fi
done

I commented all of that out (by adding # at the start of each line) and then added this.

JAVA_HOME=$(readlink -f /usr/bin/javac | sed "s:/bin/javac::")
export JAVA_HOME

Then simply restart tomcat with sudo service tomcat7 restart and a quick check in /var/log/tomcat7/localhost.2017-01-13.log (with your date in) will show if it is working.

  • thanks for your great help. i just wanted to do one more thing before I try your recommendation and it got me working in the end. check my solution above! – newbie_girl Jan 14 '17 at 18:56

This is what I did in the end.

I uninstalled everything.

First I made sure that java8 is installed over instructions @iant provided belowe in his answer (How to install Oracle Java on Ubuntu 14.04?).

Then I installed Tomcat7 again following this tutorial: http://www.negengec.com/2014/09/run-geoserver-ubuntu-tomcat7/, except line sudo apt-get install default-jdk that I didnt use, plus in the file sudo nano /etc/default/tomcat7 I have changed line with JAVA_HOME to: JAVA_HOME=/usr/lib/jvm/java-8-oracle/jre (https://stackoverflow.com/questions/29052127/how-to-setup-tomcat7-in-ubuntu-14-04-so-that-it-uses-latest-jre-of-java-8-oracle).

Then I have just unzipped Geoserver file war.zip in var/lib/tomcat7/webapps and suddenly thing was working!

I hope I havent forgotten something and also, I hope some of the previous things didnt left behind during unistallation, in that case maybe something else was the cause of making this thing work!
