Follow the instructions below to install API Manager on Linux or Mac OS X.

Installing the required applications

1. Establish a SSH connection to the Linux machine or log in on the text Linux console. You should either log in Log in to the command line (Terminal on Mac) either as root or obtain root permissions after logging in via via su or  or sudo command command.
2. Be sure Ensure that your system meets the Installation Prerequisites. Java Development Kit (JDK) is essential to run the product.  

Installing the API Manager

1. Download the latest version of the API Manager as described inin Downloading Downloadingthe Product.
   

2. Extract the archive file to a dedicated directory for the the API Manager, which will hereafter be referred to as as <APIM_HOME>.

Setting up JAVA_HOME

Anchor
JavaHome JavaHome

You must set your your JAVA_HOME environment  environment variable to point to the directory where the Java Development Kit (JDK) is installed on the computer.

...

1. In your home directory, open the BASHRC file in your favorite Linux text editor, (.bash_profile file
 on Mac) using editors such as vi, emacs, pico, or mcedit.

2. Assuming you have JDK 1.6.0_25 in your system, add the following two lines at the bottom of the file, replacing replacing /usr/java/jdk1.6.0_25 with  with the actual directory where the JDK is installed.

   Code Block
   On Linux: export JAVA_HOME=/usr/java/jdk1.6.0_25 export PATH=${JAVA_HOME}/bin:${PATH}

   The file should now look like this:

   On OS X: export JAVA_HOME=/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

3. Save the file.

   Info
   If you do not know how to work with text editors in a Linux SSH session, run the following command: cat >> .bashrc. Paste the string from the clipboard and press "Ctrl+D."

4. To verify that

   the

   the JAVA_HOME

   variable

    variable is set correctly, execute the following command:

   Code Block
   On Linux: echo $JAVA_HOME

   On OS X: which java If the above command gives you a path like /usr/bin/java, then it is a symbolic link to the real location. To get the real location, run the following: ls -l `which java`

5. The system returns the JDK installation path.

Setting system properties

If you need to set additional system properties when the server starts, you can take the following approaches:

• Set the properties from a script: Setting your system properties in the startup script is ideal, because it ensures that you set the properties every time you start the server. To avoid having to modify the script each time you upgrade, the best approach is to create your own startup script that wraps the WSO2 startup script and adds the properties you want to set, rather than editing the WSO2 startup script directly.
• Set the properties from an external registry: If you want to access properties from an external registry, you could create Java code that reads the properties at runtime from that registry. Be sure to store sensitive data such as username and password to connect to the registry in a properties file instead of in the Java code and secure the properties file with the the secure vault.

You are now ready to to run the product.
