我正在尝试在 Centos 6 上创建一个服务,但它是在启动控制台上执行的,而不是在后台执行的,这意味着它永远不会到达用户界面 - 它只是挂在启动显示屏上。
服务如下:
#!/bin/bash
#
# run red5 server
#
# chkconfig: 5 70 30
# description: app server
# processname: red5
# Source function library.
. /etc/init.d/functions
RETVAL=0
prog="red5"
LOCKFILE=/var/lock/subsys/$prog
# Declare variables for red5 Server
ANALYTICS_DIR=/home/engineering/SVP/app-server
start() {
echo -n "Starting $prog: "
cd $ANALYTICS_DIR
daemon ./red5.sh
RETVAL=$?
[ $RETVAL -eq 0 ] && touch $LOCKFILE
echo
return $RETVAL
}
stop() {
echo -n "Shutting down $prog: "
cd $ANALYTICS_DIR
nohup ./red5-stop.sh && success || failure
RETVAL=$?
[ $RETVAL -eq 0 ] && rm -f $LOCKFILE
echo
return $RETVAL
}
status() {
echo "stub"
}
case "$1" in
start)
start
;;
stop)
stop
;;
status)
status
;;
这是 red5.sh 脚本(运行另一个脚本)
#!/bin/bash
if [ -z "$RED5_HOME" ]; then
export RED5_HOME=`pwd`;
fi
export JAVA_OPTS="${JAVA_OPTS} -Xms1g -Xmx1g -Xss256K"
LOG_OPTS="-DSERVER_LOGS=/var/opt/SVP/svp-server/log"
source ${RED5_HOME}/red5-start.sh
这是 red5-start.sh
#!/bin/bash
if [ -z "$RED5_HOME" ]; then
export RED5_HOME=`pwd`;
fi
P=":" # The default classpath separator
OS=`uname`
case "$OS" in
CYGWIN*|MINGW*) # Windows Cygwin or Windows MinGW
P=";" # Since these are actually Windows, let Java know
;;
Darwin*)

*)
# Do nothing

esac
echo "Running on " $OS
# JAVA options
# You can set JAVA_OPTS to add additional options if you want
JAVA_OPTS="$JAVA_OPTS -Xverify:none -XX:+TieredCompilation -XX:+UseBiasedLocking -XX:+UseParNewGC -XX:InitialCodeCacheSize=8m -XX:ReservedCodeCacheSize=32m -Dorg.terracotta.quartz.skipUpdateCheck=true"
# Set up logging options

# Set up security options

# Set up MySQL encryption
export APP_ENC=encrypt
# Set up Java system property for location of the application server log files
export JAVA_OPTS="$LOGGING_OPTS $SECURITY_OPTS $JAVA_OPTS $LOG_OPTS"
if [ -z "$RED5_MAINCLASS" ]; then
export RED5_MAINCLASS=org.red5.server.Bootstrap
fi
# Jython options
JYTHON="-Dpython.home=lib"
#for JAVA in "${JAVA_HOME}/bin/java" "${JAVA_HOME}/Home/bin/java" "/usr/bin/java" "/usr/local/bin/java"
for JAVA in "${JAVA_HOME}/bin/java" "${JAVA_HOME}/Home/bin/java" "/usr/bin/java" "/usr/local/bin/java"
do
if
[ -x "$JAVA" ]
then
break
fi
done
export JAVA=/usr/bin/java
if [ ! -x "$JAVA" ]
then
break
fi
done
export JAVA=/usr/bin/java
if [ ! -x "$JAVA" ]
then
echo "Unable to locate Java. Please set JAVA_HOME environment variable."
exit
fi
export RED5_CLASSPATH="${RED5_HOME}/red5-service.jar${P}${RED5_HOME}/lib/mail.jar${P}${RED5_HOME}/conf${P}${CLASSPATH}"
# start Red5
echo "Starting Red5"
echo "JAVA is: $JAVA"
exec "$JAVA" "$JYTHON" -Dred5.root="${RED5_HOME}" $JAVA_OPTS -cp "${RED5_CLASSPATH}" "$RED5_MAINCLASS" $RED5_OPTS
问题是否在于服务正在调用另一个脚本?
我是否需要将 red5-start.sh 作为 red5 的守护进程运行?我宁愿不这样做,而且我知道它以前作为服务运行过,无需这样做。只是我没有最初设置的服务的副本,所以我想弄清楚它是如何工作的。
答案1
您是否尝试过将最后一行更改为:
exec "$JAVA" "$JYTHON" -Dred5.root="${RED5_HOME}" $JAVA_OPTS -cp "${RED5_CLASSPATH}" "$RED5_MAINCLASS" $RED5_OPTS &
它应该在后台运行 Java。
