Install Tomcat 9 on CentOS 7.7 EN

From PlcWiki

Jump to: navigation, search

they write that: 

HTTP/2 (requires either running on Java 9 (since Apache Tomcat 9.0.0.M18) or the Tomcat Native library being installed)

CentOS 7.7 shows Open JDK version 1.8: 

# java -version
openjdk version "1.8.0_232"
OpenJDK Runtime Environment (build 1.8.0_232-b09)
OpenJDK 64-Bit Server VM (build 25.232-b09, mixed mode)

So I'd rather install Tomcat Native library like this: 

yum install apr-devel openssl-devel

I stick to what I saw in our recent installations and unpack the Tomcat to / home / 

tar xvzf apache-tomcat-9.0.xx.tar.gz --directory /home/

Link to the usual place in / var / 

ln -s /home/apache-tomcat-9.0.33/ /var/apache-tomcat-9.0.33

Create an init script in the /etc/init.d directory 

Honza Vejvoda can do that. I just copied it from an already running tomcat8 and edited it.

This is how I generated the signed certificate: 

openssl pkcs12 -export -out certificate.pfx -inkey a6442s115.autoexpr.com.key -in a6442s115_B64.cer
openssl pkcs12 -in certificate.pfx -out mypermfile.pem
openssl pkcs12 -export -in mypermfile.pem -out tomcatkeystore.p12 -name "TomcatCert"

It asks for passwords so I used Tomcat's default "changeit"
