The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /usr/java/jdk1.6.0_30/jre/lib/i386/server:/usr/java/jdk1.6.0_30/jre/lib/i386:/usr/java/jdk1.6.0_30/jre/../lib/i386:/usr/java/packages/lib/i386:/lib:/usr/lib |
从上面内容中告诉我们，可以使用Native library来提高和优化性能。接下来就是安装,我们在支持yum命令的系统中可以使用
我自己也写了一个shell脚本程序来安装最新版本的tomcat-native-connector,脚本内容如下:

里面的某些参数注意修改成自己具体需求的,然后重新启动tomcat可以看到如下信息:
