tomcat6出现错误日志：
信息: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib
解决：
通过安装和配置apr解决。
Tomcat Native 可以让 Tomcat 使用 Apache 的 apr 包来处理包括文件和网络IO操作，以提升性能。
1.安装：yum -y install openssl-devel
2.下载：apr-1.4.6.tar.gz、apr-util-1.4.1.tar.bz2、tomcat-native-1.1.19-src.tar.gz
（下载地址：http://archive.apache.org/dist/tomcat/tomcat-connectors/native/）
3.安装apr：
tar -xzf apr-1.4.6.tar.gz
cd apr-1.4.6
./configure && make && make install
tar -xjf apr-util-1.4.1.tar.bz2
cd apr-util-1.4.1
./configure --with-apr=/usr/local/apr && make && make install
tar -xzf tomcat-native-1.1.19-src.tar.gz
cd /opt/tomcat-native-1.1.19-src/jni
./configure --with-apr=/usr/local/apr --with-java-home=/opt/jdk && make && make install
4.设置apr的环境变量：
vi /etc/profile
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/apr/lib
保存退出
source /etc/profile
再查看catalina.out日志，发现不再报错了：
信息: An older version 1.1.19 of the APR based Apache Tomcat Native library is installed, while Tomcat recommends a minimum version of 1.1.22
