The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /usr/java/jdk1.5.0_22/jre/lib/i386/client:/usr/java/jdk1.5.0_22/jre/lib/i386:/usr/java/jdk1.5.0_22/jre/../lib/i386:/usr/java

上面错误貌似对我项目的业务不影响。但每次看到这个问题于心不忍。这里分享一个解决方案

参考http://wander312.iteye.com/blog/1132975 写的非常好，感谢这个同学分享。

pr 与 tomcat-native 提供更好的伸缩性、性能和集成到本地服务器技术。

如果没有apr技术，启动tomcat 时出现如下提示：

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/jdk1.5.0_22/jre/lib/i386/client:/usr/java/jdk1.5.0_22/jre/lib/i386:/usr/java/jdk1.5.0_22/jre/../lib/i386:/usr/java
按照官方说明需要：

APR library
OpenSSL libraries
openssl 可以用 yum install openssl-devel，apr还是下载*.gz来安装。

a）apr-1.3.2.tar.gz(下载URL:http://www.apache.org/dist/apr/apr-1.5.1.tar.gz)
b）apr-util-1.3.2.tar.gz(下载URL:http://www.apache.org/dist/apr/apr-util-1.3.12.tar.gz)
c）tomcat-native.tar.gz 可以在tomcat/bin目录下找到。

1）安装 apr
wget http://apache.mirror.phpchina.com/apr/apr-1.5.1.tar.gz
tar zxvf apr-1.5.1.tar.gz
cdapr-1.5.1
./configure
make
make install
apr 默认安装在 /usr/local/apr

2）安装 apr-util
wget http://apache.mirror.phpchina.com/apr/apr-util-1.5.3.tar.gz
tar zxvf apr-util-1.5.3.tar.gz
cd apr-util-1.5.3
./configure --with-apr=/usr/local/apr
make
make install

3）安装 tomcat-native
cd /usr/local/tomcat-6.0.37/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/java/jdk1.5.0_22
make
make install

4）设置 apr 的环境变量：
vi /etc/profile
# 后面添加以下内容
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/apr/lib
# 使profile生效，
source /etc/profile
启动 tomcat 后，看日志：

bin/startup.sh
head logs/catalina.out
可以看到以下结果：

信息: Loaded APR based Apache Tomcat Native library 1.1.14.
2009-1-13 11:12:51 org.apache.catalina.core.AprLifecycleListener init
信息: APR capabilities: IPv6 [true], sendfile [true], accept filters [false], random [true].
