Terima kasih kepada Mark untuk tautan ke skrip itu; di sini adalah contoh kerja saya untuk CentOS:
#!/bin/bash
# Source: https://confluence.atlassian.com/plugins/viewsource/viewpagesrc.action?pageId=252348917
function shutdown()
{
date
echo "Shutting down Tomcat"
unset CATALINA_PID # Necessary in some cases
unset LD_LIBRARY_PATH # Necessary in some cases
unset JAVA_OPTS # Necessary in some cases
$TOMCAT_HOME/bin/catalina.sh stop
}
date
echo "Starting Tomcat"
export CATALINA_PID=/tmp/$$
export JAVA_HOME=/usr/local/java
export LD_LIBRARY_PATH=/usr/local/apr/lib
export JAVA_OPTS="-Dcom.sun.management.jmxremote.port=8999 -Dcom.sun.management.jmxremote.password.file=/etc/tomcat.jmx.pwd -Dcom.sun.management.jmxremote.access.file=/etc/tomcat.jmxremote.access -Dcom.sun.management.jmxremote.ssl=false -Xms128m -Xmx3072m -XX:MaxPermSize=256m"
# Uncomment to increase Tomcat's maximum heap allocation
# export JAVA_OPTS=-Xmx512M $JAVA_OPTS
. $TOMCAT_HOME/bin/catalina.sh start
# Allow any signal which would kill a process to stop Tomcat
trap shutdown HUP INT QUIT ABRT KILL ALRM TERM TSTP
echo "Waiting for `cat $CATALINA_PID`"
wait `cat $CATALINA_PID`
Dan inilah yang saya gunakan di /etc/supervisord.conf:
[program:tomcat]
directory=/usr/local/tomcat
command=/usr/local/tomcat/bin/supervisord_wrapper.sh
stdout_logfile=syslog
stderr_logfile=syslog
user=apache
Berjalan, tampilannya seperti ini:
[root@qa1.qa:~]# supervisorctl start tomcat
tomcat: started
[root@qa1.qa:~]# supervisorctl status
tomcat RUNNING pid 9611, uptime 0:00:03
[root@qa1.qa:~]# ps -ef|grep t[o]mcat
apache 9611 9581 0 13:09 ? 00:00:00 /bin/bash /usr/local/tomcat/bin/supervisord_wrapper.sh start
apache 9623 9611 99 13:09 ? 00:00:10 /usr/local/java/bin/java -Djava.util.logging.config.file=/usr/local/tomcat/conf/logging.properties -Dcom.sun.management.jmxremote.port=8999 -Dcom.sun.management.jmxremote.password.file=/etc/tomcat.jmx.pwd -Dcom.sun.management.jmxremote.access.file=/etc/tomcat.jmxremote.access -Dcom.sun.management.jmxremote.ssl=false -Xms128m -Xmx3072m -XX:MaxPermSize=256m -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.endorsed.dirs=/usr/local/tomcat/endorsed -classpath /usr/local/tomcat/bin/bootstrap.jar -Dcatalina.base=/usr/local/tomcat -Dcatalina.home=/usr/local/tomcat -Djava.io.tmpdir=/usr/local/tomcat/temp org.apache.catalina.startup.Bootstrap start
Saya awalnya mencoba menambahkan variabel lingkungan ke /etc/supervisord.conf melalui environment
arahan, tetapi mengalami masalah dengan JAVA_OPTS, dengan semua spasi dan tanda sama dengan. Menempatkannya di skrip pembungkus merawat itu.
Semoga ini bisa membantu menghemat waktu orang lain!
start
pada akhir perintah di /etc/supervisord.conf adalah argumen yang tidak perlu karena skrip tidak melakukan apa-apa dengannya.
