Installing Apache portable runtime (APR) for tomcat 6.0.x

Tomcat can now use Apache Portable Runtime and using APR results in performance boost.
Below we detail the steps to get tomcat native library installed on a linux system
(I am using Red hat but steps should be similar for other distros)

Download and install APR

wget http://apache.norhex.com/apr/apr-1.3.3.tar.gz
    mkdir x
    mv apr-1.3.3.tar.gz x/
    408  tar -zxvf apr-1.3.3.tar.gz
    409  cd apr-1.3.3
    416  gcc -v
    417  ./configure --prefix=/opt/apr
    418  make
    419  make install

Download and compile openssl tarball corresponding to your system
(Latest version maybe incompatible with your system)

       424  openssl version -a
      426  wget http://www.openssl.org/source/openssl-0.9.8b.tar.gz
      427  tar -zxvf openssl-0.9.8b.tar.gz
      429  cd openssl-0.9.8b
      431  ./Configure
      433  ./config --prefix=/opt/apr --openssldir=/opt/openssl shared
      434  make
      435  make test
      436  make install
 

Download and install sun JDK .

You have to put /usr/java/latest/bin in your path to pick SUN JDK ahead of GCJ.

 
       466  uname -a
      467  java -version
      468  links http://java.sun.com/javase/downloads/index.jsp
      chmod +x jdk-6u10-linux-i586-rpm.bin
      411  ./jdk-6u10-linux-i586-rpm.bin
      418  /usr/java/latest/bin/java -version
      419  echo $PATH
      423  vi .bash_profile
      424  . .bash_profile
      425  echo $PATH
      426  java -version


  

Download and install tomcat native source

  
   443  wget http://tomcat.heanet.ie/native/1.1.10/source/tomcat-native-1.1.10-src.tar.gz
  444  tar -zxvf tomcat-native-1.1.9-src.tar.gz
  445  cd tomcat-native-1.1.10-src/jni/native
  464  ./configure  --help
  440  ./configure --prefix=/opt/apr/ --with-ssl=/opt/apr --with-apr=/opt/apr
           --with-java-home=/usr/java/latest --with-java-platform=2
   460  make
   467  make install
   468  ls /opt/apr/lib/
   469  ldd /opt/apr/lib/libtcnative-1.so.0
   

if configure complains about not finding openSSL then set LD_LIBRARY_PATH to include /opt/apr/lib.

  454  echo $LD_LIBRARY_PATH
  455  LD_LIBRARY_PATH=/opt/apr/lib
  456  export LD_LIBRARY_PATH
 

Put tomcat native library in LD_LIBRARY_PATH before starting tomcat. Start tomcat and check catalina log file to verify that tomcat is using APR.

  
# setup native library in path
LD_LIBRARY_PATH=/opt/apr/lib:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH
/usr/local/apache-tomcat-6.0.16/bin/startup.sh
