This is kind of connected to an earlier post but I didn't want to get
shouted at for hijacking so I started new one, hope this is OK
apache-tomcat-7.0.42 standalone web server
CentOS Linux release 7.2.1511
jdk1.7.0_45 and jdk1.8.0_77
It's a bit complicated I'll try to be brief
On discovering that browsers complained that I was using obsolete
cyphers over https I discovered that running the server against java
1.8 solved the problem.
I'm using a tried and tested init.d script
on my test machine, (Ubuntu Linux 12.10) in the script,
/etc/rc.d/init.d/tomcat7 I changed
JAVA_HOME=/opt/jdk1.7.0_45
to
JAVA_HOME=/opt/jdk1.8.0_77
saved the script and started tomcat under jsvc
The server came up straight away and browsers informed me that I was
using modern up to date ciphers ... hooray, change one line and
everything hums.
So, on the CentOS box I had exactly the same script in exactly the
same place pointing to exactly the same jdk (/opt/jdk1.7.0_45)
I realise that this CentOS release uses systemd init but if I shut
down tomcat with
# systemctl stop tomcat.service
I can start it manually with the old init.d script. it's quicker and
I don't have to keep reloading services. It works, Tomcat starts up
and ssllabs give me a big fat F for fail as expected but
I'm running fine with https. browsers still complain (as expected) but
it proves that my SSL config is correct (or as correct as can be
expected given the circumstances).
So, # /etc/rc.d/init.d/tomcat7 stop
change
JAVA_HOME=/opt/jdk1.7.0_45
to
JAVA_HOME=/opt/jdk1.8.0_77
/etc/rc.d/init.d/tomcat7 start ... epic fail
With the messages
Cannot find any VM in Java Home /opt/jdk1.8.0_77
Cannot locate JVM library file
in the tomcat logs
I have set everything I can think of including JAVA_HOME in .bash_profile
[root@vps logs]# java -version
java version "1.8.0_77"
Java(TM) SE Runtime Environment (build 1.8.0_77-b03)
Java HotSpot(TM) 64-Bit Server VM (build 25.77-b03, mixed mode)
[root@vps logs]# echo $PATH
/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/lyallex/.local/bin:/home/lyallex/bin:/opt/jdk1.8.0_77/bin
but nothing I do changes anything.
I have copied the start script below fYI
Has anyone seen anything like this before?
Thanks
