Tomcat 성능향상을 위해 APR + OPENSSL + Native-Connector 를 추가 설치 !!!
이렇게 하면 믿거나 말거나 성능이 엄청 올라가서 apache httpd서버를 이용할 필요가 없다고 한다. ???
특히 SSL을 톰캣이 직접처리하도록 하려면 반드시 해야될 작업이라고 합니다.
APR 라이브러리 설치하기
(참조 :
http://tomcat.apache.org/tomcat-7.0-doc/apr.html

)
Most Linux distributions will ship packages for APR and OpenSSL. The JNI wrapper (libtcnative) will then have to be compiled. It depends on APR, OpenSSL, and the Java headers.
Requirements:
- APR 1.2+ development headers (libapr1-dev package)
- OpenSSL 0.9.7+ development headers (libssl-dev package)
- JNI headers from Java compatible JDK 1.4+
- GNU development environment (gcc, make)
The wrapper library sources are located in the Tomcat binary bundle, in the bin/tomcat-native.tar.gz archive. Once the build environment is installed and the source archive is extracted, the wrapper library can be compiled using (from the folder containing the configure script):

| ./configure && make && make install | |

아래와 같이 처리함.
$CATALINA_HOME/bin/catalina.sh 파일안에 아래와 같이 LD_LIBRARY_PATH 를 추가 해준다.
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/home/mulder/apps/tomcat7/lib"
아래와 같이 로그가 올라오면 성공이다.
