tcserver

Overview

https://content.pivotal.io/blog/part-one-comparing-apache-tomcat-and-pivotal-tc-server
Pivotal tc server builds on top of Apache Tomcat and adds a few key features:

• Enterprise support (with purchased license)
• Multi-instance support with shared binaries - individual runtime instances allows a separation between the binaries and the applications/configuration, allowing one set of binaries to power multiple instances.
• Variable substitution within server.xml - allows for consistent configuration and port management

Note: Pivotal tcserver 3.x is available through the pivotal repo, however to get the latest version, 4.x, you need to download and install the RPM from pivnet manually.

Installing tcserver 3.x - Linux

In this example we will be installing tcserver 3.x on a CentOS 7 vm using the pivotal repo.

Adding the Pivotal Repo and installing the package

Accept the EULA

~$ wget -q -O - http://packages.pivotal.io | sudo sh

Verify you see the new package

~$ sudo yum search pivotal-tc-server-standard

Install tcserver, ant, and java

~$ sudo yum install pivotal-tc-server-standard ant java-1.8.0-openjdk

Setting the user variables

To discover your Java home variable, you need to find the executable location and then use that to discover JAVA_HOME. You will need to omit /jre if it appears in your java_home results.

~$ which java
/bin/java
~$ /bin/java -XshowSettings:properties -version 2>&1 > /dev/null | grep 'java.home'
java.home = /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.181-3.b13.el7_5.x86_64/jre

Ant HOME should always be /usr/share/ant

With both the JAVA_HOME and ANT_HOME found, we can set the following in our bash profile. Make sure to omit /jre from your JAVA_HOME:

export JAVA_HOME="/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.181-3.b13.el7_5.x86_64"
export ANT_HOME="/usr/share/ant"
export PATH=$PATH:$JAVA_HOME/bin

You can use the following to append the variables in your bash profile, make sure to update the variables to match your versions.

~$ echo -e export JAVA_HOME='"'/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.181-3.b13.el7_5.x86_64'"'"\n"export ANT_HOME='"'/usr/share/ant'"'"\n"export PATH='$PATH:$JAVA_HOME/bin' >> ~/.bash_profile

NOTE: I would set the user variables to both your sudo capable user AND the tcserver user.

Testing with Hello World app

With tcserver installed and its dependencies configured, we can test it with a simple hello world java app.

~$ git clone https://github.com/carefreepineapple/hello-world-war.git
