Unpack the packages to /root/apache/apr-1.5.2 and /root/apache/apr-util-1.5.4

./configure --prefix=/usr/local/apr

For Tomcat
Compile and install tomcat native
Go to tomcat/bin, unpack tomcat-native.tar.gz, then go to tomcat-native-1.1.29-src/jni/native, compile and install tomcat-native

# /home/root/apache-tomcat-7.0.53/bin/tomcat-native-1.1.29-src/jni/native
./configure --with-apr=/usr/local/apr --with-java-home=/usr/lib/jvm/java-VERSION-oracle/
make
make install

Configuration
In the start script of Tomcat, add

CATALINA_OPTS="$CATALINA_OPTS -Djava.library.path=/usr/local/apr/lib"

In conf/server.xml, update protocol of connectors to use the following protocols,

org.apache.coyote.http11.Http11AprProtocol
org.apache.coyote.ajp.AjpAprProtocol

Restart tomcat, if you see the following in the catalina.out and no exception, the APR is running.

在Ubuntu中更改时区

上次按网上说的用 拷贝文件的方式改就吃过亏了，cron应该是读取/etc/timezone来进行调度的。在Ubunut上正确修改时区的命令应该是

dpkg-reconfigure tzdata

更改后

fp@fp2:~$ cat /etc/localtime
TZif2UTCTZif2UTC
UTC0
 
fp@fp2:~$ cat /etc/timezone 
Etc/UTC
 
fp@fp2:~$ date
Sun Sep 7 11:13:52 UTC 2014

Ubuntu 中升级至 JDK7

sudo apt-get update
sudo apt-get install software-properties-common python-software-properties
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer
sudo update-alternatives --config java
