Editor to share with you how to configure Tomcat8.0.44 under Linux to use Apr. I hope you will get something after reading this article. Let's discuss it together.

The configuration is as follows

1. Install apr 1.5.2

[root@ecs-3c46] # cd / usr/local/src [root@ecs-3c46 src] # wget http://apache.fayea.com//apr/apr-1.5.2.tar.gz[root@ecs-3c46 src] # tar-xzvf apr-1.5.2.tar.gz [root@ecs-3c46 src] # cd apr-1.5.2 [root@ecs-3c46 apr-1.5.2] #. / configure-- prefix=/usr/local/apr [root@ Ecs-3c46 apr-1.5.2] # make [root@ecs-3c46 apr-1.5.2] # make install

two。 Install apr-util-1.5.4

[root@ecs-3c46] # cd / usr/local/src [root@ecs-3c46 src] # wget http://mirrors.hust.edu.cn/apache//apr/apr-util-1.5.4.tar.gz[root@ecs-3c46 src] # tar-xzvf apr-util-1.5.4.tar.gz [root@ecs-3c46 src] # cd apr-util-1.5.4 [root@ecs-3c46 apr-util-1.5.4] #. / configure -- prefix=/usr/local/apr [root@ecs-3c46 apr-util-1.5.4] # make [root@ecs-3c46 apr-util-1.5.4] # make install

3. If you do not have openssl installed, please install openssl. If you have already installed, continue to the next step.

4. Install the tomcat-native component and find that there is already a related file tomcat-native.tar.gz in the bin directory of tomcat8.0.44

Decompress and get the tomcat-native-1.2.12-src folder.

[root@ecs-3c46 bin] # tar-xzvf tomcat-native.tar.gz [root@ecs-3c46 bin] # cd tomcat-native-1.2.12-src/native [root@ecs-3c46 native] #. / configure-with-apr=/usr/local/apr-with-java-home=/usr/local/java/jdk1.7.0_80-with-ssl=/usr/local/openssl-prefix=/usr/local/tomcat/apache-tomcat-8.0.44 [root@ Ecs-3c46 native] # make [root@ecs-3c46 native] # make install

5.tomcat configuration. Apr is enabled by default for tomcat8.0.44, which is configured on Listener nodes.

A problem occurs after restarting the tomcat service, indicating that Apr has not been successfully used

27-Jul-2017 15:50:13.488 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

Solution:

Create a link to / usr/local/apr/lib/libtcnative-1.so.0.2.12 under the / usr/java/packages/lib/amd64 directory

[root@ecs-3c46 native] # cd / usr/java/ [root@ecs-3c46 java] # mkdir packages/ [root@ecs-3c46 java] # cd packages/ [root@ecs-3c46 packages] # mkdir lib [root@ecs-3c46 packages] # cd lib [root@ecs-3c46 lib] # mkdir amd64 [root@ecs-3c46 lib] # cd amd64 [root@ecs-3c46 amd64] # ln-s / usr/local/apr/lib/libtcnative-1.so.0.2.12 libtcnative-1.so [root@ecs-3c46 amd64] # ln-s / usr/local/apr/lib/libtcnative--1.so.0.2.12 libtcnative-1.so.0

6. Restart tomcat, and if the following message is displayed, it means that the configuration is successful.
