　　# cd $CATALINA_HOME/bin
　　# tar -zxvf tomcat-native.tar.gz
　　# cd tomcat-native-1.1.27-src/jni/native
　　# ./configure --with-apr=/usr/local/apr --with-java-home=/usr/local/jdk1.8.0_91

　　The native libraries were installed in /usr/local/apr/lib
　　
Integrate APR with Tomcat
There are two ways to set Tomcat integrate with APR. One is you can add the following parameter when start up the Tomcat in bin/catalina.sh:
CATALINA_OPTS="-Djava.library.path=/usr/local/apr/lib"The other is to add a new environment variable LD_LIBRARY_PATH in /etc/profile:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/apr/libThen makes it effect via:
# source /etc/profileAfter restarting the Tomcat service, we can get the following message in catalina.out log if APR was installed successfully.
