java Tomcats启动时的警告消息

Question

我在启动tomcat服务器时收到以下消息：

org.apache.catalina.core.AprLifecycleListener.lifecycleEvent 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/lib/x86_64-linux-gnu/jni:/lib/x86_64-linux-gnu:/usr/lib/x86_64-linux-gnu:/usr/lib/jni:/lib:/usr/lib

尽管我已经安装了apr和其他类似的东西：

sudo apt-get install zlib1g-dev build-essential libapr1 libapr1-dev libssl-dev libreadline-dev -y

在这里我找到了安装它所需的信息： http://tomcat.apache.org/native-doc/

您还需要安装libtcnative，这是Tomcat实际调用的JNI库
