 Posted: Tue Sep 06, 2005 9:51 am Post subject: tomcat won't start |
 |
|
My tomcat always worked fine. But since I rebootet my machine the last time it hangs while starting. I rebootet because I compiled a new kernel (2.6.12), but I don't think that's the reason because tomcat behaves the same when booting the old 2.4 kernel.
The tomcat version is 5.0.27-r6. I have two jdks installed: blackdown-jdk-1.4.2.02 and sun-jdk1.5.0_01. I tried both, it does not work.
Here's the catalina.out:

It seems that tomcat starts and then stops, but the process does not return and I get no error message.
I removed all webapps and reinstalled tomcat without success.
Has anyone an idea? Thanks! |

Same problem here, no solution yet.
After "emerge unmerge tomcat && rm -r /opt/tomcat /etc/tomcat"
I reinstalled tomcat tomcat-5.0.27-r6 again
No change.
| Code: | # java-config -L
[sun-jdk-1.5.0.05] "Sun JDK 1.5.0.05" (/etc/env.d/java/20sun-jdk-1.5.0.05) * |

Same for me, just emerged today
| Code: | | [ebuild R ] www-servers/tomcat-5.0.27-r6 -doc -jikes 0 kB |
and I have
| Code: | # java-config -L
[blackdown-jre-1.4.2.02] "Blackdown JRE 1.4.2.02" (/etc/env.d/java/20blackdown-jre-1.4.2.02)
[blackdown-jdk-1.4.2.02] "Blackdown JDK 1.4.2.02" (/etc/env.d/java/20blackdown-jdk-1.4.2.02) * |
This is the log, it tries to shutdown immediately after starting.
| Code: | Nov 19, 2005 10:08:46 AM org.apache.catalina.startup.Catalina start

Then it hangs with java and runscript.sh using some CPU and I have to kill manually the child runscript.sh process (BTW, why two?)
| Code: | # ps -efw | grep runscript
root 11837 8955 0 10:25 pts/3 00:00:00 /bin/bash /sbin/runscript.sh /etc/init.d/tomcat5 start
root 11887 11837 1 10:25 pts/3 00:00:02 /bin/bash /sbin/runscript.sh /etc/init.d/tomcat5 start
# kill 11887
# ps -efw | grep runscript
root 18410 12505 0 10:28 pts/2 00:00:00 grep runscript |
Any ideas? Thanks in advance.

An update. If I start it manually
| Code: | | /opt/tomcat5/bin/catalina.sh start |
it works without problems, and it works too if I run
| Code: | | start-stop-daemon --start --quiet --chuid tomcat:tomcat --exec /opt/tomcat5/bin/catalina.sh -- start |
that is the exact command executed by the init script
| Code: | # cat /etc/init.d/tomcat5
#!/sbin/runscript

depend() {
use dns logger mysql postgresql net
}
start() {
ebegin "Starting Tomcat"
start-stop-daemon --start --quiet --chuid tomcat:tomcat --exec ${CATALINA_HOME}/bin/catalina.sh -- ${TOMCAT_START}
sleep 5
eend $?
}
stop() {
ebegin "Stopping Tomcat"
start-stop-daemon --start --quiet --chuid tomcat:tomcat --exec ${CATALINA_HOME}/bin/catalina.sh -- ${TOMCAT_STOP}
sleep 5
eend $?
} |
given that /etc/conf.d/tomcat5 has
| Code: | CATALINA_HOME=/opt/tomcat5
TOMCAT_START="start"
TOMCAT_STOP="stop" |
I can't understand why.

OK, this a self service forum  .
Now I see what's happening
| Code: | ++ rc_start_daemon
++ eval /sbin/start-stop-daemon ''\''--start'\'' '\''--quiet'\'' '\''--chuid'\'' '\''tomcat:tomcat'\'' '\''--exec'\'' '\''/opt/tomcat5/bin/catalina.sh'\'' '\''--'\'' '\''start'\'''
+++ /sbin/start-stop-daemon --start --quiet --chuid tomcat:tomcat --exec /opt/tomcat5/bin/catalina.sh -- start
++ local retval=0
++ [[ 0 != \0 ]]
++ [[ 0.1 == \0 ]]
++ LC_ALL=C
++ /bin/sleep 0.1
++ is_daemon_running /opt/tomcat5/bin/catalina.sh ''
++ local cmd pidfile pids pid
++ [[ 2 == \1 ]]
++ local i j=2
++ (( i=0 ))
++ (( i<j-1 ))
++ cmd=' /opt/tomcat5/bin/catalina.sh'
++ shift
++ (( i++ ))
++ (( i<j-1 ))
++ pidfile=
+++ pidof /opt/tomcat5/bin/catalina.sh
+++ local arg args
+++ for arg in '"$@"'
+++ [[ catalina.sh == \r\p\c\.\n\f\s\d ]]
+++ args=' '\''/opt/tomcat5/bin/catalina.sh'\'''
+++ eval /bin/pidof -x ''\''/opt/tomcat5/bin/catalina.sh'\'''
++++ /bin/pidof -x /opt/tomcat5/bin/catalina.sh
++ pids=
++ [[ -z '' ]]
++ return 1
++ retval=1
++ [[ 1 == \0 ]]
+++ type -t stop
++ [[ function == \f\u\n\c\t\i\o\n ]]
++ stop |
The start function in tomcat init script ends up to call rc_start_deamon in /lib/rcscripts/sh/rc-daemon.sh (because start-stop-daemon is wrapped by a function in the same file, this happens only when start-stop-deamon is called by /sbin/runscript.sh, and it works if called directly from bash). Immediately (or more precisely 0.1 s) after the real /sbin/start-stop-daemon is called, it appears to the is_daemon_running function (by calling pidof -x with the script name as argument) that the service went down, so stop is called.
These are the function definitions from /lib/rcscripts/sh/rc-daemon.sh in sys-apps/baselayout-1.12.0_pre10-r1
| Code: | # bool is_daemon_running(char* cmd, char* pidfile)
#
# Returns 0 if the given daemon is running, otherwise 1
# If a pidfile is supplied, the pid inside it must match
# a pid in the list of pidof ${cmd}
is_daemon_running() {
local cmd pidfile pids pid
if [[ $# == "1" ]]; then
cmd="$1"
else
local i j="$#"
for (( i=0; i<j-1; i++ )); do
cmd="${cmd} $1"
shift
done
pidfile="$1"
fi
pids=$( pidof ${cmd} )
[[ -z ${pids} ]] && return 1
[[ -s ${pidfile} ]] || return 0
read pid < "${pidfile}"
pids=" ${pids} "
[[ ${pids// ${pid} } != "${pids}" ]]
}
# int rc_start_daemon(void)
#
# We don't do anyting fancy - just pass the given options
# to start-stop-daemon and return the value
rc_start_daemon() {
eval /sbin/start-stop-daemon "${args}"
local retval="$?"
[[ ${retval} != "0" ]] && return "${retval}"
[[ ${RC_WAIT_ON_START} == "0" ]] && return "${retval}"
# We pause for RC_WAIT_ON_START seconds and then
# check if the daemon is still running - this is mainly
# to handle daemons who launch and then fail due to invalid
# configuration files
LC_ALL=C /bin/sleep "${RC_WAIT_ON_START}"
is_daemon_running ${cmd} "${pidfile}"
retval="$?"
[[ ${retval} == "0" ]] && return 0
# Stop if we can to clean things up
if [[ $( type -t stop ) == "function" ]]; then
stop >/dev/null # We don't want to echo ebegin/eend
elif [[ -n ${pidfile} ]]; then
rc_stop_daemon
fi
return "${retval}"
} |
So probably the tomcat init script is not compatible with this version of baselayout. I'll try to check differences with stable version.
In the meantime, any idea about how to solve it?

OK, I didn't searched enough. There's a bug filed against 5.0.28-r4, that seems to be solved for all 5.0.28 ebuilds. For 5.0.27 I patched init script as suggested, changing start-stop-daemon in /sbin/start-stop-daemon.
