Introduction
This article will help you to Install Tomcat 9 on CentOS, Red Hat and Fedora systems. To install other version of tomcat visit Tomcat 8 on CentOS & Red Hat. Step 1 – Verify JAVA. Tomcat 9 is designed to run on Java SE 8 and later. So make sure you have installed correct version on your system. Sep 06, 2013 CentOS: Installing Apache Portable Runtime (APR) for Tomcat. To boost the Tomcat performance, the alternative ways either adapt NIO (Non-Blocking I/O) or APR (Apache Portable Runtime) connector. Especially, the APR performance is generally better than others when using SSL protocol. For more details on performance among these connectors can reference the Mike. Hello, I have installed Alfresco 3.4D on Rhel 5.6 and I have this message in the log during the startup: INFO: The APR based Apache Tomcat Native. Tagged as: Apache Tomcat catalina.out, Apache Tomcat Install Error, Apache Tomcat Install Issue, Apache Tomcat JAVA_HOME, Apache Tomcat JRE_HOME, Apache Tomcat setenv.sh, CentOS Tomcat Install, Debian Tomcat Install, Fedora Tomcat Install, Linux Tomcat Restart, RedHat Tomcat Install, Start Tomcat Linux, Stop Tomcat Linux, Ubuntu Tomcat Install. Install Tomcat on CentOS In this article, we will guide you through the steps of installing Tomcat 9 on CentOS 7. Apache Tomcat is the most popular and widely used Java application server. It is an open source web server and servlet container developed by the Apache Software Foundation.
Apache Tomcat is an open-source web server that is designed to serve Java web pages. It is widely deployed and powers various mission-critical web applications around the world. As a starter guide, this article explains how to install Apache Tomcat 8, the latest stable version of Apache Tomcat, onto a Vultr CentOS 7 server instance. Just want to point out that the tomcat-native-1.1.20-src changes with each new version. So that should be addressed. Also backup of files before they are removed would be good idea just in case you need to roll back.
The Apache Tomcat Native Library is an optional component for use with Apache Tomcat that allows Tomcat to use certain native resources for performance, compatibility, etc.
Specifically, the Apache Tomcat Native Library gives Tomcat access to the Apache Portable Runtime (APR) library's network connection (socket) implementation and random-number generator. See the Apache Tomcat documentation for more information on how to configure Tomcat to use the APR connector.
Features of the APR connector:
- Non-blocking I/O for Keep-Alive requests (between requests)
- Uses OpenSSL for TLS/SSL capabilities (if supported by linked APR library)
- FIPS 140-2 support for TLS/SSL (if supported by linked OpenSSL library)

Headlines
- 15 December 2015 - TC-Native-1.1.34released
The Apache Tomcat team is proud to announce the immediate availability ofTomcat Native 1.1.34 Stable.
The sources and the binaries for selected platforms are available from the Download page.
Please see the ChangeLog for a full list of changes.
Building
Requirements
Build tc-native requires three components to be installed:
- APR library
- OpenSSL libraries
- Java SE Development Kit (JDK)
In debian based Linux those dependencies could be installed by something like:
In rpm based Linux those dependencies could be installed by something like:
UNIX
Restart Tomcat Centos
On all the POSIX systems (Linux, Solaris, HP-UX, AIX etc..) a well-known configure and make is used to build tc-native.
In the jni/native runs:
to read the description of all the parameters.
to create the includes and makefiles to be able to build tc-native.
Where:$HOME/APR is something like /usr/bin/apr-1-config or the path where apr is installed.$JAVA_HOME is something /home/jfclere/JAVA/jdk1.5.0_09 path to a JDK installation. Any JDK should work but it is advisable to use the same JVM version the JVM you use with Tomcat.$HOME/OPENSSL is the path where OpenSSL is installed.$CATALINA_HOME is the path where the produced libraries will be installed. Something like $HOME/apache-tomcat-6.0.16/
The configure is able to guess most of OpenSSL standard installations. So most of the time the following will be enough:
To build the libraries and install them:
The libraries will be found in $CATALINA_HOME/lib
Windows
Download the windows sources of tc-native and extract them.
Install Tomcat Native Library Centos Commands
Download OpenSSL sources (See Binary Distributions) OpenSSL is a crypto software so check if you are allowed to download it. If not you can still use tc-native without SSL.
Download APR sources for Windows. (See Download) Extract them in jni and rename the apr-1.x.y directory to apr.
Use MS Visual Studio to open the workspace of the APR sources and build the library (libapr).
Use MS Visual Studio to open the workspace of the tc-native sources, adjust the OpenSSL includes and libraries location change the name of the libraries libeay32 and libssleay to libeay32MT and libssleayMT and build the tcn-native library. That should create a tcnative-1.dll.
Install and tests
Configuring Tomcat
Centos Tomcat Configuration
Apache Tomcat comes with the AprLifecycleListener enabled by default. Still, you should check your conf/server.xml to ensure that something like the following is present, and uncommented:
Please see the Apache Tomcat documentation for configuration specifics.
UNIX
Edit $CATALINA_HOME/bin/setenv.sh (creating the file if necessary) and add the path to the tc-native libraries to LD_LIBRARY_PATH. Something like:
Start tomcat and check for the messages like this ones:
Refer to the tomcat documentation to configure the connectors (See Tomcat6.0.x and Tomcat5.5.x)
Windows
The Apr Based Apache Tomcat Native Library
Bonus bot keygen idm. Edit $CATALINA_BASEbinsetenv.bat (creating the file if necessary) and add the path to the tc-native libraries, apr and OpenSSL to PATH. For example:
Start tomcat and check for the messages like this ones:
