Question

我正在尝试编写一个简短的bash脚本来自动加载战争，以便保留我在tomcat服务器上的配置文件。但是，有时当我尝试在脚本中停止tomcat时，它会给我这个错误：

Using CATALINA_BASE:   /usr/local/apache-tomcat-6.0.32~
Using CATALINA_HOME:   /usr/local/apache-tomcat-6.0.32~
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-6.0.32~/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /usr/local/apache-tomcat-6.0.32~/bin/bootstrap.jar

我最初认为这是因为我在完全启动它之前试图关闭服务器，而且可能仍然如此。但是，我在脚本中添加了一个部分，用于在关闭服务器之前检查以确保服务器已启动。然后，因为我有时会得到错误，我增加了一些睡眠时间。如果我让它睡10秒钟，它似乎一直工作，但如果我让它只睡5，它就不那么一致。我认为这归结于我不熟悉tomcat的启动和关闭顺序，所以我不确定我的问题是否是我认为的问题，我不知道什么是一个好的，万无一失的解决方案。因此，我的问题是：导致此错误的原因是什么，如果它是由服务器未完全启动引起的，我的代码的哪些更改可以防止错误？

我的剧本：

#!/bin/bash
# Script to redeploy war, needs path to the new war

if [ ! -f $1 ];
then
    echo "File $1 not found! Get it right this time."
    exit 0;
fi
#Check if tomcat is up, if it is, shut 'er down
RESULT=`netstat -na | grep 8080 | awk '{print $7}' | wc -l`
if [ "$RESULT" = 0 ]; then
echo "Tomcat already down"
elif [ "$RESULT" != 0 ]; then
echo "Shutting down tomcat"
./shutdown.sh;
fi
cp ../webapps/SQLLoader/conf/configurable.properties ..;
rm ../webapps/SQLLoader -R;
echo "SQLLoader dir removed";
rm ../webapps/SQLLoader.war;
echo "SQLLoader removed";
cp $1 ../webapps;
echo "$1 moved to tomcat";
./startup.sh;
wait
echo "Server started";
echo "Waiting for dir to be created..."
while [ ! -d "../webapps/SQLLoader/conf" ]; do
    # Control will enter here if directory doesn't exist
    sleep 1
done;
mv ../configurable.properties ../webapps/SQLLoader/conf/;
echo "Config file put back in place";
RESULT=`netstat -na | grep 8080 | awk '{print $7}' | wc -l`
while [ "$RESULT" = 0 ]; do
    echo "Waiting for tomcat to start... JUST SO WE CAN KILL IT AGAIN HAHAHAHAHA!!"
    sleep 0.5
    RESULT=`netstat -na | grep 8080 | awk '{print $7}' | wc -l`
done;
echo "Sleep for safety"
sleep 5;
echo "Shutting down again"
./shutdown.sh
echo "Starting... again...... yeah..."
./startup.sh
echo "Status is: $?"

因此，我发现我的具体问题的解决方案是简单地使用jar命令（duh）来解压战而不是重新启动服务器。这是我的新代码：

#!/bin/bash
# Script to redeploy war, needs path to the new war

if [ ! -f $1 ];
then
    echo "File $1 not found! Get it right this time."
    exit 0;
fi
#Check if tomcat is up, if it is, shut 'er down
RESULT=`netstat -na | grep $2 | awk '{print $7}' | wc -l`
if [ "$RESULT" = 0 ]; then
echo "Tomcat already down"
elif [ "$RESULT" != 0 ]; then
echo "Shutting down tomcat"
./shutdown.sh;
fi
cp ../webapps/SQLLoader/conf/configurable.properties ..;
rm ../webapps/SQLLoader -R;
echo "SQLLoader dir removed";
rm ../webapps/SQLLoader.war;
echo "SQLLoader removed";
cp $1 ../webapps;
echo "$1 moved to tomcat";
mkdir ../webapps/SQLLoader/
cd ../webapps/SQLLoader/
jar -xvf ../SQLLoader.war;
echo "Waiting for dir to be created..."
while [ ! -d "conf" ]; do
    # Control will enter here if directory doesn't exist
    sleep 1
done;
echo "Directory created, moving properties file";
cd ../../bin;
mv ../configurable.properties ../webapps/SQLLoader/conf/;
echo "Starting up"
./startup.sh
echo "Status is: $?"

它没有回答如何最终阻止错误的问题，但它确实解决了我的微观世界中的问题。如果有人想出为什么在之前解释的情况下发生错误的原因，请发布，因为我相信人们仍然有兴趣知道答案。
