在 Tomcat 启动脚本中增加 Java 的堆空间

在 Tomcat 启动脚本中增加 Java 的堆空间

我想在使用 Tomcat 时增加堆大小。有人告诉我添加此行

导出CATALINA_OPTS=-Xms16m -Xmx256m；

进入 startup.sh 脚本 - 我这样做了（一开始），但得到了错误

导出：24：-Xmx256m：错误的变量名

我应该把它添加到哪里，我是否做错了什么？

<b>export CATALINA_OPTS=-Xms16m -Xmx256m;</b>
# Better OS/400 detection: see Bugzilla 31132
os400=false
darwin=false
case "`uname`" in
CYGWIN*) cygwin=true;;
OS400*) os400=true;;
Darwin*) darwin=true;;
esac

# resolve links - $0 may be a softlink
PRG="$0"

while [ -h "$PRG" ] ; do
  ls=`ls -ld "$PRG"`
  link=`expr "$ls" : '.*-> \(.*\)$'`
  if expr "$link" : '/.*' > /dev/null; then
PRG="$link"
  else
    PRG=`dirname "$PRG"`/"$link"
  fi
done

PRGDIR=`dirname "$PRG"`
EXECUTABLE=catalina.sh

# Check that target executable exists
if $os400; then
# -x will Only work on the os400 if the files are: 
# 1. owned by the user
# 2. owned by the PRIMARY group of the user
# this will not work if the user belongs in secondary groups
eval
    else
    if [ ! -x "$PRGDIR"/"$EXECUTABLE" ]; then
    echo "Cannot find $PRGDIR/$EXECUTABLE"
    echo "This file is needed to run this program"
    exit 1
fi
fi 

exec "$PRGDIR"/"$EXECUTABLE" start "$@"

答案1

您是否尝试过将它们括在双引号中？

export CATALINA_OPTS="-Xms16m
-Xmx256m"

答案2

您需要删除行末的“；”。
