It was supposed to be as easy as
1 2 3 | sudo ./configuresudo makesudo 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 “gcc” and “make”, let alone Apache APR. Thanks God, networking was not an issue, unlike last time.
1 2 3 4 5 6 7 8 | wget http://apache.spd.co.il/apr/apr-1.4.5.tar.gztar -xzf apr-1.4.5.tar.gzrm apr-1.4.5.tar.gzcd apr-1.4.5/sudo apt-get install makesudo ./configuresudo makesudo make install |
2. Installing Tomcat Native.
1 2 3 4 5 | wget http://off.co.il/apache//tomcat/tomcat-connectors/native/1.1.20/source/tomcat-native-1.1.20-src.tar.gztar -xzf tomcat-native-1.1.20-src.tar.gzrm tomcat-native-1.1.20-src.tar.gzcd tomcat-native-1.1.20-src/jni/nativesudo ./configure --with-apr=/usr/local/apr |
The result was
1 2 3 4 5 | 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?
1 2 3 4 5 6 7 8 | $ which java/home/user/java/jdk/bin/java$ echo $JAVA_HOME/home/user/java/jdk$ java -versionjava 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:
01 02 03 04 05 06 07 08 09 10 11 12 13 14 | ..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:
1 2 3 4 | sudo ln -s ~/java/jdk/ /usr/local/jdk-1.6sudo ./configure --with-apr=/usr/local/aprsudo makesudo make install |
And with
1 2 3 | ..export LD_LIBRARY_PATH='$LD_LIBRARY_PATH:/usr/local/apr/lib'.. |
I now had a beautiful log message in “catalina.out“:
1 2 3 4 5 6 7 | ..Mar 7, 2011 11:51:02 PM org.apache.catalina.core.AprLifecycleListener initINFO: Loaded APR based Apache Tomcat Native library 1.1.20.Mar 7, 2011 11:51:02 PM org.apache.catalina.core.AprLifecycleListener initINFO: 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.
