Follow the instructions below to install WSO2 Enterprise Service Bus (binary) v.4.0.2 on Linux or Solaris from the command line.
Note
Before you install the ESB, ensure that your system meets the minimum hardware and software requirements described in ESB Installation Prerequisites.
Establish a SSH connection to the Linux/Solaris machine or log in on the text Linux console. You should either log in as root or obtain root permissions after login via su or sudo command.
Step 1. Obtain Installation Pack
Download the latest version of the program (for downloading instructions, see Obtaining ESB).
Step 2. Extract the Archive
After the download is complete, extract installation files to your home directory, by executing the following command:
unzip wso2esb-4.0.2.zip
Step 3. Set up JAVA_HOME
JAVA_HOME environment variable set up is needed to run WSO2 ESB. The variable points at the directory where the Java™ Development Kit (JDK) is installed on the computer.
Reference
Environment variables are global system variables accessible by all the processes running under the operating system.
Edit BASHRC file in your home directory to add the JAVA_HOME environment variable. To set up JAVA_HOME, perform the following steps.
1. Open the BASHRC file in your favorite Linux text editor - vi, emacs, pico, or mcedit.
2. Add the following two (2) lines at the bottom of the file:
export JAVA_HOME=/usr/java/jdk1.6.0_25
export PATH=${JAVA_HOME}/bin:${PATH}
3. Save the file.
Tip
If you do not know how to work with text editors in Linux SSH session, run the following command:
cat >> .bashrc
Paste the string from the clipboard and press "Ctrl+D."
4. In order to verify the effective JAVA_HOME variable set up, execute the following command:
echo $JAVA_HOME
The system returns the JDK installation path.
Step 4. Access ESB Management Console
ESB is installed and environment variables are set up. Proceed to Starting ESB Management Console on Linux and Solaris for the instructions on how to run the ESB Management Console.
