The Apache Portable Runtime (APR) is
a supporting library for the Apache web server.
It provides a set of APIs that
map to the underlying operating system (OS). Where the OS doesn't support a
particular function, APR will provide an emulation. Thus programmers can use
the APR to make a program truly portable across platforms.
In
this document we will see how we can install APR for Tomcat on a Linux Machine.
1.
Install Apache APR from here
2. tar
-xvf apr-1.5.0.tar.gz
3. cd apr-1.5.0
4. ./configure
5. make
6. make install
3. cd apr-1.5.0
4. ./configure
5. make
6. make install
1.
Install Tomcat Connectors from Here
2.
tar -xvf tomcat-native-1.1.29-src.tar.gz
3. cd
tomcat-native-1.1.29-src
4.
cd jni/
5. cd native/
6. ./configure --with-apr=/usr/local/apr(a dot before says to execute in current location)
7.make
8.make install
9.export LD_LIBRARY_PATH='$LD_LIBRARY_PATH:/usr/local/apr/lib'
10 cd /usr/local/apr/
5. cd native/
6. ./configure --with-apr=/usr/local/apr(a dot before says to execute in current location)
7.make
8.make install
9.export LD_LIBRARY_PATH='$LD_LIBRARY_PATH:/usr/local/apr/lib'
10 cd /usr/local/apr/
Now
we can go to /usr/local/apr to see that Runtime portable is installed.
Start
the Tomcat and see the following message in Cataline.out file
Nov 21, 2013 4:42:53 PM org.apache.catalina.core.AprLifecycleListener init
INFO: Loaded APR based Apache Tomcat Native library 1.1.29 using APR version 1.5.0.

More
to Come. Happy learning
