APR(Apache Portable Runtime)的安装

APR(Apache Portable Runtime)
==============
（1）apr安装
tar xvf apr-1.2.8.tar
cd apr-1.2.8
./configure
make & make install
=============
（2）apr connector安装
tar -xzvf <tomcat_dir>/bin/tomcat-native.tar.gz
cd tomcat-native-1.1.6-src/jni/native
mkdir /usr/local/apr-connector
./configure --with-apr=/usr/local/apache-test/bin/apr-1-config --prefix=/usr/local/apr-connector
make & make install
=============
（3）tomcat使用apr
load libtcnative和libapr库
ln -s /usr/local/apr/lib/libapr-1.so /usr/local/lib/libapr-1.so
ln -s /usr/local/apr-connector/lib/libtcnative-1.so /usr/local/lib/libtcnative-1.so
在startup.sh中加入
export LD_LIBRARY_PATH = /usr/local/lib
否则报“找不到相应的库”
The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /opt/tomcat/apr-connector/lib:/usr/local/lib

可选:(不需配置，如果有apr支持，会自动用apr)
在Connector中加入
protocol="org.apache.coyote.http11.Http11AprProtocol"
