setenv.sh中的多行JAVA_OPTS [英] Multiline JAVA_OPTS in setenv.sh

问题描述

我正在尝试在Ubuntu 12 / Tomcat 7上设置我的 setenv.sh 。
Tomcat已经安装了apt-get
I我试图创建一个多行 JAVA_OPTS 变量，但一直遇到错误消息。

I'm trying to setup my setenv.sh on Ubuntu 12/Tomcat 7. Tomcat has been installed with apt-get I've tried to create a multiline JAVA_OPTS variable but keep running into error messages.

#!/bin/sh
export JAVA_OPTS="$JAVA_OPTS -server \
-Xms512m -Xmx512m"

: not foundtomcat7/bin/catalina.sh: 4: /usr/share/tomcat7/bin/setenv.sh:

#!/bin/sh
export JAVA_OPTS="$JAVA_OPTS -server -Xms512m -Xmx512m"

我已将其更新为此，但在回显位置仅显示最后一行。

I've updated it to this, but at the echo location only the last line is displayed.

#!/bin/sh
JAVA_OPTS="$JAVA_OPTS -server -Xms704m -Xmx704m"
JAVA_OPTS="$JAVA_OPTS -XX:OnOutOfMemoryError=/usr/share/scripts/on_server_crash.sh"
JAVA_OPTS="$JAVA_OPTS -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/log/tomcat7"
JAVA_OPTS="$JAVA_OPTS -XX:MaxPermSize=128m -XX:MaxNewSize=256m -XX:NewSize=256m"
echo $JAVA_OPTS
JAVA_OPTS="$JAVA_OPTS -XX:SurvivorRatio=12 -XX:MaxTenuringThreshold=0"
JAVA_OPTS="$JAVA_OPTS -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode"
JAVA_OPTS="$JAVA_OPTS -XX:+CMSIncrementalPacing -XX:+CMSClassUnloadingEnabled"
JAVA_OPTS="$JAVA_OPTS -XX:+CMSPermGenSweepingEnabled -XX:+DisableExplicitGC"
JAVA_OPTS="$JAVA_OPTS -XX:+UseParNewGC -XX:+UseTLAB"
JAVA_OPTS="$JAVA_OPTS -Djava.awt.headless=true"
JAVA_OPTS="$JAVA_OPTS -javaagent:$NR_JAR -Dnewrelic.environment=production"
echo $JAVA_OPTS
export JAVA_OPTS

当我尝试每个命令在它自己的行没有导出选项，我得到无法识别的选项-server

When I try "each command on its own line" without the export option, I get "unrecognized option -server

#!/bin/sh
JAVA_OPTS="$JAVA_OPTS -server"
JAVA_OPTS="$JAVA_OPTS -Xms704m"
JAVA_OPTS="$JAVA_OPTS -Xmx704m"
JAVA_OPTS="$JAVA_OPTS -XX:OnOutOfMemoryError=/usr/share/scripts/on_server_crash.sh"
JAVA_OPTS="$JAVA_OPTS -XX:+HeapDumpOnOutOfMemoryError"
JAVA_OPTS="$JAVA_OPTS -XX:HeapDumpPath=/var/log/tomcat7"
JAVA_OPTS="$JAVA_OPTS -XX:MaxPermSize=128m"
JAVA_OPTS="$JAVA_OPTS -XX:MaxNewSize=256m"
JAVA_OPTS="$JAVA_OPTS -XX:NewSize=256m"
JAVA_OPTS="$JAVA_OPTS -XX:SurvivorRatio=12"
JAVA_OPTS="$JAVA_OPTS -XX:MaxTenuringThreshold=0"
JAVA_OPTS="$JAVA_OPTS -XX:+UseConcMarkSweepGC"
JAVA_OPTS="$JAVA_OPTS -XX:+CMSIncrementalMode"
JAVA_OPTS="$JAVA_OPTS -XX:+CMSIncrementalPacing"
JAVA_OPTS="$JAVA_OPTS -XX:+CMSClassUnloadingEnabled"
JAVA_OPTS="$JAVA_OPTS -XX:+CMSPermGenSweepingEnabled"
JAVA_OPTS="$JAVA_OPTS -XX:+DisableExplicitGC"
JAVA_OPTS="$JAVA_OPTS -XX:+UseParNewGC"
JAVA_OPTS="$JAVA_OPTS -XX:+UseTLAB"
JAVA_OPTS="$JAVA_OPTS -Djava.awt.headless=true"
JAVA_OPTS="$JAVA_OPTS -javaagent:$NR_JAR"
JAVA_OPTS="$JAVA_OPTS -Dnewrelic.environment=production"
echo JAVA_OPTS

推荐答案

嗯，删除整个文件并重新创建它，现在它可以工作.....
现在使用这种风格

Hmm, deleted the whole file and recreated it, and now it works..... Now using this style

export JAVA_OPTS="$JAVA_OPTS\
 -server\
 -Xms704m\
 -Xmx704m\
 -XX:OnOutOfMemoryError=/usr/share/scripts/on_server_crash.sh\
 -XX:+HeapDumpOnOutOfMemoryError\
 -XX:HeapDumpPath=/var/log/tomcat7\
 -XX:MaxPermSize=128m\
 -XX:MaxNewSize=256m\
 -XX:NewSize=256m\
 -XX:SurvivorRatio=12\
 -XX:MaxTenuringThreshold=0\
 -XX:+UseConcMarkSweepGC\
 -XX:+CMSIncrementalMode\
 -XX:+CMSIncrementalPacing\
 -XX:+CMSClassUnloadingEnabled\
 -XX:+CMSPermGenSweepingEnabled\
 -XX:+DisableExplicitGC\
 -XX:+UseParNewGC\
 -XX:+UseTLAB\
 -Djava.awt.headless=true\
 -javaagent:$NR_JAR\
 -Dnewrelic. environment=production"
