docker下面tomcat执行startup.sh问题

zhouln

在做docker的时候,碰到了如果使用startup.sh是无法成功启动tomcat,
一定要使用catalina.sh run
后来看到文章: ant sshexec 无法启动tomcathttp://www.lxway.com/61161411.htm, 然后参考catalina.sh的详解: http://www.cnblogs.com/huzhiwei/archive/2012/03/13/2393393.html
发现: 运行startup.sh的时候,程序进入到
elif [ "$1" = "start" ] ; then
echo "Tomcat started------->start."
if [ ! -z "$CATALINA_PID" ]; then
if [ -f "$CATALINA_PID" ]; then
if [ -s "$CATALINA_PID" ]; then
echo "Existing PID file found during start."
if [ -r "$CATALINA_PID" ]; then
PID=`cat "$CATALINA_PID"`
ps -p $PID >/dev/null 2>&1
if [ $? -eq 0 ] ; then
echo "Tomcat appears to still be running with PID $PID. Start aborted."
echo "If the following process is not a Tomcat process, remove the PID file and try again:"
ps -f -p $PID
exit 1
else
echo "Removing/clearing stale PID file."
rm -f "$CATALINA_PID" >/dev/null 2>&1
if [ $? != 0 ]; then
if [ -w "$CATALINA_PID" ]; then
cat /dev/null > "$CATALINA_PID"
else
echo "Unable to remove or clear stale PID file. Start aborted."
exit 1
fi

echo "Unable to read PID file. Start aborted."

rm -f "$CATALINA_PID" >/dev/null 2>&1
if [ $? != 0 ]; then
if [ ! -w "$CATALINA_PID" ]; then
echo "Unable to remove or write to empty PID file. Start aborted."
exit 1

if [ "$1" = "-security" ] ; then

echo "Using Security Manager"

echo "Tomcat started------->started->security"
shift
eval "\"$_RUNJAVA\"" "\"$LOGGING_CONFIG\"" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \

else
echo "Tomcat started------->started->no security"
eval "\"$_RUNJAVA\"" "\"$LOGGING_CONFIG\"" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \
-Djava.endorsed.dirs="\"$JAVA_ENDORSED_DIRS\"" -classpath "\"$CLASSPATH\"" \

fi
if [ ! -z "$CATALINA_PID" ]; then
echo $! > "$CATALINA_PID"
fi
echo "Tomcat started."

问题出在于:org.apache.catalina.startup.Bootstrap "$@" start \
      >> "$CATALINA_OUT" 2>&1 "&"  重定向了日志之后,有多了一个&符号, 是这个符号导致启动失败的.  去掉就好了.
