I've built/installed Tomcat 7.0.29 from source on linux/64.
I've setup an init.d using jsvc launch, loosely based on the src-bundled
daemon.sh script.
@ tomcat service launch, using out-of-the-box config for now, I see two
listeners on ONE pid,
netstat -pan --tcp | grep jsvc
tcp 0 0 :::8080 :::*
LISTEN 30891/jsvc.exec
tcp 0 0 :::8009 :::*
LISTEN 30891/jsvc.exec
but note that actually TWO procs/pids exist,
ps ax | grep jsvc
30890 ? Ss 0:00 jsvc.exec -user tomcat
-java-home /etc/alternatives/java_sdk -pidfile
/var/run/tomcat7/tomcat7.pid -classpath
/usr/local/tomcat7/build/bin/bootstrap.jar:/usr/local/tomcat7/build/bin/commons-daemon.jar:/usr/local/tomcat7/build/bin/tomcat-juli.jar
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=/usr/local/etc/tomcat7/conf/logging.properties
-Djava.endorsed.dirs=
-Dcatalina.base=/usr/local/tomcat7/build
-Dcatalina.home=/usr/local/tomcat7/build
-Djava.io.tmpdir=/var/tmp/tomcat7 -outfile
/var/log/tomcat7/tomcat-initd.log -errfile &1 -wait 10
org.apache.catalina.startup.Bootstrap
30891 ? Sl 0:03 jsvc.exec -user tomcat
-java-home /etc/alternatives/java_sdk -pidfile
/var/run/tomcat7/tomcat7.pid -classpath
/usr/local/tomcat7/build/bin/bootstrap.jar:/usr/local/tomcat7/build/bin/commons-daemon.jar:/usr/local/tomcat7/build/bin/tomcat-juli.jar
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=/usr/local/etc/tomcat7/conf/logging.properties
-Djava.endorsed.dirs=
-Dcatalina.base=/usr/local/tomcat7/build
-Dcatalina.home=/usr/local/tomcat7/build
-Djava.io.tmpdir=/var/tmp/tomcat7 -outfile
/var/log/tomcat7/tomcat-initd.log -errfile &1 -wait 10
org.apache.catalina.startup.Bootstrap
I want only a *single* instance of tomcat running.
Seeing these TWO pids, is that actually TWO instaces?
Reading @ https://commons.apache.org/daemon/jsvc.html
How jsvc works
Jsvc uses 3 processes: a launcher process, a controller process
and a controlled process. ...
I suspect it's not, and I'm just seeing those ^^^, but wanted to get
some clarification.
Thanks.
