在ubuntu 14.04上安装tomcat 8.0.24

Question

I follow the steps largely from https://www.digitalocean.com/community/tutorials/how-to-install-apache-tomcat-8-on-ubuntu-14-04

Let me iterate the steps I took:

1. i logged in as ubuntu user
2. sudo apt-get install tomcat8
3. sudo groupadd tomcat
4. sudo useradd -s /bin/false -g tomcat -d /opt/tomcat tomcat
5. cd ~
6. wget http://apache.mirrors.ionfish.org/tomcat/tomcat-8/v8.0.24/bin/apache-tomcat-8.0.24.tar.gz
7. sudo mkdir /opt/tomcat
8. sudo tar xvf apache-tomcat-8*tar.gz -C /opt/tomcat --strip-components=1
9. cd /opt/tomcat
10. sudo chgrp -R tomcat conf
11. sudo chmod g+rwx conf
12. sudo chmod g+r conf/*
13. sudo chown -R tomcat work/ temp/ logs/
14. sudo update-alternatives --config java and selected /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java
15. sudo nano /etc/init/tomcat.conf

and typed

description "Tomcat Server"

  start on runlevel [2345]
  stop on runlevel [!2345]
  respawn
  respawn limit 10 5

  setuid tomcat
  setgid tomcat

  env JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/jre
  env CATALINA_HOME=/opt/tomcat

  # Modify these options as needed
  env JAVA_OPTS="-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom"
  env CATALINA_OPTS="-Xms512M -Xmx1024M -server -XX:+UseParallelGC"

  exec $CATALINA_HOME/bin/catalina.sh run

  # cleanup temp directory after stop
  post-stop script
    rm -rf $CATALINA_HOME/temp/*
  end script

16. sudo initctl reload-configuration
17. sudo initctl start tomcat

which leads to

tomcat start/running, process 14674

But when I go to http://[ip-address]:8080 nothing happens.

Please advise.

UPDATE

One comment below asked me to look at server.xml inside tomcat root folder bin.

I have reproduced the following files:

Which proves that there is no such file inside /opt/tomcat/bin

I have also appended some statements from server.xml below which is inside /opt/tomcat/conf

<Connector port="8080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
<Server port="8005" shutdown="SHUTDOWN">

Answer 1

Just use

sudo chown -R tomcat:tomcat /opt/tomcat

This worked for me after useing the very same manual.

Answer 2

If you want clean Ubuntu style package instead, the following should do it...

mkdir $HOME/tomcat8 && cd $HOME/tomcat8
wget http://mirrors.kernel.org/ubuntu/pool/main/e/ecj/libecj-java_3.10.1-2_all.deb
wget http://mirrors.kernel.org/ubuntu/pool/universe/t/tomcat8/libservlet3.1-java_8.0.28-1_all.deb
wget http://mirrors.kernel.org/ubuntu/pool/universe/t/tomcat8/libtomcat8-java_8.0.28-1_all.deb
wget http://mirrors.kernel.org/ubuntu/pool/universe/t/tomcat8/tomcat8-common_8.0.28-1_all.deb
wget http://mirrors.kernel.org/ubuntu/pool/universe/t/tomcat8/tomcat8_8.0.28-1_all.deb
dpkg -i *.deb

However, you're not on PPA. This isn't managed by apt anymore. You'll need to upgrade it manually whenever an update is made to the packages.

I had the same problem. I installed Oracle JDK 7 , HOWEVER, I still used JAVA_HOME in tomcat.conf that was pointing to Open JDK :

env JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64/jre

Make sure you are using the right version of Java. For me, I set it in tomcat.conf as follows:

env JAVA_HOME=/usr/lib/jvm/java-7-oracle/jre

Then, do ps -ef | grep tomcat ps -ef | grep tomcat after re-starting tomcat and you should get something like this if tomcat is running:

tomcat    1580     1  9 14:47 ?        00:00:03 /usr/lib/jvm/java-7-oracle/jre/bin/java -Djava.util.logging.config.file=/opt/tomcat/conf/logging.properties -Dja
ger=org.apache.juli.ClassLoaderLogManager -Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom -Xms128m -Xmx256m -XX:PermSize=128m -XX:MaxPermSize=2
ParallelGC -Djava.endorsed.dirs=/opt/tomcat/endorsed -classpath /opt/tomcat/bin/bootstrap.jar:/opt/tomcat/bin/tomcat-juli.jar -Dcatalina.base=/opt/tomcat -Dcat
t -Djava.io.tmpdir=/opt/tomcat/temp org.apache.catalina.startup.Bootstrap start
ubuntu    1607  1423  0 14:48 pts/0    00:00:00 grep --color=auto tomcat

Also, my environment file has the following:

export JAVA_HOME="/usr/lib/jvm/java-7-oracle/jre"
export CATALINA_HOME="/opt/tomcat"

Hope this helps!

Answer 4

Instead of: http://serverip:8080 I used http://localhost:8080

That replacement worked for me.

I have simple solution for installing any version of apache tomcat on Ubuntu.

Simplest Way of Installing any version Apache Tomcat Installation Steps on Ubuntu.

1. Download any version of tomcat you wish to install from apache tomcat official website.(.tar/.zip)

2. Extract the tomcat tar/zip file to any folder/directory in your linux pc.

3. Copy the extracted folder to /opt directory directory looks like /opt/tomcat using cp command.

   for eg sudo cp /Documents/apache-tomcat-8-0-24 /opt

   This will copy my apache-tomcat-8-0-24 folder in Documents folder to /opt directory.

4. come back to /opt directory /opt cd /opt

5. you are at /opt run following command sudo chown -R username:username

   for eg sudo chown -R akashgudadhe apache-tomcat-8-0-24

6. you are at /opt ls -la verify apache present or not

7. move to apache-tomcat-8-0-24 folder and bin directory inside it

   /opt/apacheTomcatName/bin

8. you are now at /opt/apacheTomcatName/bin

   run startup.sh file using following command you will see the message tomcat started.

   for eg /opt/apacheTomcatName/bin/./startup.sh

9. This is optional step tail -f logs/catalina.out

10. Open any web browser and type localhost:8080 or type 127.0.0.1:8080 your tomcat installed successfully if not then mail me @ gooddaysky1@gmail.com

It will become great pleasure for me if you send me your feedback about my answer @ gooddaysky1@gmail.com ...!!!

Answer 6

打开Server.xml并找到<Connector port="9090" protocol="HTTP/1.1" ，这是您的端口号。

Answer 7

You have to write:
cd /opt/tomcat/bin

and after:

sudo bash startup.sh

and all well!!! http://serverip:8080

NOTE: If you put the port 9090, then PLACED IN YOUR BROWSER http://serverip:9090
