在安装好jdk与tomcat之后，会在tomcat启动log信息里提示：

27-Aug-2018 08:59:49.191 INFO [main] 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/lib64:/lib64:/lib:/usr/lib]

tar.gz版本的tomcat不会安装好apr，需要单独编译安装。

http://apr.apache.org/

去这里下载

丢到服务器上面去
解压，安装

tar -zxvf apr-1.6.3.tar.gz

./configure && make && make install

去tomcat的bin目录下，解压tomcat-native.tar.gz

tar -zxvf tomcat-native.tar.gz

去刚才解压好的目录下的native中

cd apache-tomcat-8.5.33/bin/tomcat-native-1.2.17-src/native/

./configure --with-apr=/usr/local/apr --with-java-home=$JAVA_HOME

make && make install

修改环境变量

vim /etc/profile

在最后增加

export LD_LIBRARY_PATH=/usr/local/apr/lib

source /etc/profile
