Ubuntu: Installing Apache Portable Runtime (APR) for Tomcat
It was supposed to be as easy as
sudo ./configure sudo make sudo make install
but as you may guess, it was a little bit more than that.
1. Installing Apache APR.
“Most Linux distributions will ship packages for APR” – those of Linode don’t, I had a barebone Ubuntu 10.10 box without even
"make", let alone Apache APR. Thanks God, networking was not an issue, unlike last time.
wget http://apache.spd.co.il/apr/apr-1.4.5.tar.gz tar -xzf apr-1.4.5.tar.gz rm apr-1.4.5.tar.gz cd apr-1.4.5/ sudo apt-get install make sudo ./configure sudo make sudo make install
2. Installing Tomcat Native.
wget http://off.co.il/apache//tomcat/tomcat-connectors/native/1.1.20/source/tomcat-native-1.1.20-src.tar.gz tar -xzf tomcat-native-1.1.20-src.tar.gz rm tomcat-native-1.1.20-src.tar.gz cd tomcat-native-1.1.20-src/jni/native sudo ./configure --with-apr=/usr/local/apr
The result was
checking build system type... x86_64-unknown-linux-gnu .. checking for APR... yes .. checking for JDK location (please wait)... checking Try to guess JDK location... configure: error: can't locate a valid JDK location
Ouch! “Can’t locate a valid JDK location” ? On my machine?
$ which java /home/user/java/jdk/bin/java $ echo $JAVA_HOME /home/user/java/jdk $ java -version java version "1.6.0_24" Java(TM) SE Runtime Environment (build 1.6.0_24-b07) Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02, mixed mode)
But for some reason
"tomcat-native-1.1.20-src/jni/native/configure" script didn’t see my
"JAVA_HOME" variable no matter what and even installing
"sun-java6-jdk" didn’t help much. After patching the
"configure" script to dump locations it was looking for “valid JDK” I had:
.. configure: [/usr/local/1.6.1] configure: [/usr/local/IBMJava2-1.6.0] configure: [/usr/local/java1.6.0] configure: [/usr/local/java-1.6.0] configure: [/usr/local/jdk1.6.0] configure: [/usr/local/jdk-1.6.0] configure: [/usr/local/1.6.0] configure: [/usr/local/IBMJava2-1.6] configure: [/usr/local/java1.6] configure: [/usr/local/java-1.6] configure: [/usr/local/jdk1.6] configure: [/usr/local/jdk-1.6] ..
Ok then, here you have it now:
sudo ln -s ~/java/jdk/ /usr/local/jdk-1.6 sudo ./configure --with-apr=/usr/local/apr sudo make sudo make install
.. export LD_LIBRARY_PATH='$LD_LIBRARY_PATH:/usr/local/apr/lib' ..
I now had a beautiful log message in
.. Mar 7, 2011 11:51:02 PM org.apache.catalina.core.AprLifecycleListener init INFO: Loaded APR based Apache Tomcat Native library 1.1.20. Mar 7, 2011 11:51:02 PM org.apache.catalina.core.AprLifecycleListener init INFO: APR capabilities: IPv6 [true], sendfile [true], accept filters [false], random [true]. Mar 7, 2011 11:51:03 PM org.apache.coyote.AbstractProtocolHandler init ..
As soon as
"evgeny-goldin.org" moves to its new location on the brand-new Linode box it will benefit from this performance optimization. I’ll describe the migration process and reasons for it a bit later, once it is done.
