I. Introduction

APR: Apache Portable Run-time libraries, Apache Portable Runtime library. In earlier versions of Apache, the application itself must be able to deal with the specific details of the operating system platform and calling different handlers for different platforms. With the further development of the Apache, Apache decided to organize these generic functions independent and develop into a new project. Thus, APR development on independence out from Apache, Apache is only using the APR only.

Tomcat Native: This project allows the use of Apache Tomcat package to deal with the apr including file and network IO operations to improve performance.

make

make install

IV. apr set environment variables

Add the following in the / etc / profile in

export LD_LIBRARY_PATH = $ LD_LIBRARY_PATH: / usr / local / apr / lib

Once saved so that profile to take effect

source / etc / profile

V. verify

cd /usr/local/apache-tomcat-7.0.63/bin /

./ catalina.sh run
