Replaced custom Java SNI implementation with a native implementation using tomcat-native, APR and OpenSSL. This should significantly improve the performance of routing HTTPS Delivery Services.
Upgraded to Tomcat 8.5.30
Separated the Traffic Router installation from the Tomcat deployment and created a new ‘tomcat’ package for installing Tomcat. Traffic Router and Tomcat can now be upgraded independently
Converted Traffic Router to a systemd(1) service
Modified the development test and deployment processes to be more consistent with production
Centos 7.9 or CentOS 8.2
OpenSSL >= 1.0.2 installed
JDK >= 8.0 installed or available in an accessible yum(8) repository
APR >= 1.4.8-3 installed or available in an accessible yum(8) repository
Tomcat Native >= 1.2.16 installed or available in an accessible yum(8) repository
tomcat >= 8.5-30 installed or available in an accessible yum(8) repository (This package is created automatically by the Traffic Router build process)
traffic_routerpackage with yum(8)

term-version string.rpm package should have been created when Traffic Router was built according to the instructions in Building Traffic Control. It must must either be added to an accessible yum(8) repository, or manually copied to the servers where Traffic Router will be installed. It is generally better that it be added to a yum(8) repository because then it will be installed automatically when Traffic Router is updated.
Update the traffic_router Package¶
tomcat_tr packages are all in an available yum(8) repository then an upgrade can be performed by running
yum update traffic_router as the root user or with sudo(8). This will first cause the
tomcat packages to be installed. When the
tomcat package runs, it will cause any older versions of
tomcat to be uninstalled. This is because the previous versions of the
traffic_router package included an untracked installation of
Restore Property Files¶
The install process does not override or replace any of the files in the
/opt/traffic_router/conf directory. Previous versions of the
startup.properties should still be good. On a new install replace the Traffic Router properties files with the correct ones for the CDN.
If a development environment is already set up for the previous version of Traffic Router, then
tomcat-native will need to be manually installed with yum(8) or rpm(8). Also, whenever either
mvn clean verify or
TrafficRouterStart is/are run, the location of the
tomcat-native libraries will need to be made known to the JVM via command line arguments.
mvn clean verify -Djava.library.path=[tomcat native library path on your box] java -Djava.library.path=[tomcat native library path on your box] TrafficRouterStart
