How to Install Tomcat Server on Linux?


Apache Tomcat is an open-source software implementation of the Java technologies like Java WebSocket, Java Expression Language technologies. To deploy any application you just need to create a war file and deploy it on tomcat. Also for more details, you can check this link.

That KB'll help you how to install tomcat on the Linux server. We ‘ll use  Red Hat  6  while performing a  new installation below.

What do you need?

  • Download  all binaries from tomcat
  • Check  Java  version.If  java  doesn’t  exist  install it.
  • Create an application mount point for specific application installation.
  • Extract file and  start  tomcat.

Let’s start the installation with the first step to download binaries. You can get all the binaries  from this link. I recommend downloading core binary distribution which named  tar.gz.

  • Download  Package:

There is two option. First, you can download package with wget command or download it from explorer then put  tar.gz  file under directory.

#wget   http://ftp.itu.edu.tr/Mirror/Apache/tomcat/tomcat-7/v7.0.65/bin/apache-tomcat-7.0.65.tar.gz 
drwxr-xr-x. 3 appdata app 4096 Nov 3 14:56 /appdata/

-bash-4.1$ 
  • Check  Java  version  .If  java  doesn’t exist download  it from  this  link.

-bash-4.1$ java -version
java version "1.7.0_45"
OpenJDK Runtime Environment (rhel-2.4.3.3.el6-x86_64 u45-b15)
OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)
-bash-4.1$ which java
/usr/bin/java
-bash-4.1$ 
  • Extract  Binary file:

**It’s  important  to extract  binary  files  with  application  user. 

-bash-4.1$ ls -ld *
-rw-r--r--. 1 appdata app 14008320 Nov 3 14:38 apache-tomcat-7.0.65.tar
drwx------. 2 root root 16384 Nov 3 12:52 lost+found
-bash-4.1$ tar -xvf apache-tomcat-7.0.65.tar |more
apache-tomcat-7.0.65/bin/catalina.sh
apache-tomcat-7.0.65/bin/configtest.sh
apache-tomcat-7.0.65/bin/daemon.sh
apache-tomcat-7.0.65/bin/digest.sh
apache-tomcat-7.0.65/bin/setclasspath.sh
  • Start  tomcat

-bash-4.1$ pwd
/appdata/apache-tomcat-7.0.65/bin
-bash-4.1$ ./startup.sh
Using CATALINA_BASE: /appdata/apache-tomcat-7.0.65
Using CATALINA_HOME: /appdata/apache-tomcat-7.0.65
Using CATALINA_TMPDIR: /appdata/apache-tomcat-7.0.65/temp
Using JRE_HOME: /usr
Using CLASSPATH: /appdata/apache-tomcat-7.0.65/bin/bootstrap.jar:/appdata/apache-tomcat-7.0.65/bin/tomcat-juli.jar
Tomcat started.
-bash-4.1$ 
  • Check Port  State

-bash-4.1$ lsof -i :8080
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
java 29647 appdata 43u IPv6 40519 0t0 TCP *:webcache (LISTEN)
-bash-4.1$ 
  • Create  an admin account for  tomcat

In the last step, we need to create an admin account for tomcat.

 

-bash-4.1$ pwd
/appdata/apache-tomcat-7.0.65/conf
-bash-4.1$ vi tomcat-users.xml 

Change  this  line as  you wish and  add them “tomcat-users.xml

<!-- user manager can access only manager section -->
<role rolename="manager-gui" />
<user username="manager" password="manager123" roles="manager-gui" />

<!-- user admin can access manager and admin section both -->
<role rolename="admin-gui" />
<user username="admin" password="admin123" roles="manager-gui,admin-gui" /
