Jenkins-java.lang.OutOfMemoryError：PermGen空间-

Question

环境：Linux / Windows7，Java 1.6.0.03/37或1.7

我下载了jenkins.war，并使用以下脚本/命令进行了初始设置后，我下载了一些插件（10-15），并尝试重新启动Jenkins，它起作用了。然后，我得到了更多的插件（总共30-40个），选择了Install或download
+ then + install，Jenkins却没有出现。

即使用startJenkins.sh（仅Linux）。注意：在Windows7上，Jenkins作为Windows服务启动。

#!/bin/bash
export JAVA_HOME=/production/jenkinsAKS/java/jdk1.6.0_03
export JENKINS_HOME=/production/jenkinsAKS
export PATH=${JAVA_HOME}/bin:${PATH}
export JENKINS_HTTP_PORT=9040
export JENKINS_AJP13_PORT=9949
now=`date +%Y%m%d_%H%M%S`

echo  $0 begins ${now}
echo "   java-home=${JAVA_HOME}, jenkins-home=${JENKINS_HOME}, path=${PATH}"
java -jar ${JENKINS_HOME}/lib/jenkins.war -XX:MaxPermSize=4096m --logfile=${JENKINS_HOME}/log/jenkins.log${now} --httpPort=${JENKINS_HTTP_PORT} --ajp13Port=${JENKINS_AJP13_PORT} &

最初，我没有使用“ -XX：MaxPermSize = 4096m”参数，但是当我看到以下错误消息时，便尝试了各种值，例如128/512 /
1024、2048、4096m等，对错误没有帮助。

或有时我看到：

-bash-3.2$

我该如何解决这个问题？当我在Windows台式机上进行相同的练习时，也会出现相同的问题。我需要使用更少或数量有限的插件吗？

谢谢

Answer 1

在〜/
.bash_profile文件中，我设置了以下3个变量。请注意，此文件中还有其他变量，例如JAVA_HOME，ANT_HOME，SONAR_HOME，SONAR_RUNNER_HOME等：

export JAVA_OPTS="-XX:MaxPermSize=512m -Xms512m -Xmx1024m"
export GRADLE_OPTS="-XX:MaxPermSize=512m"
export SONAR_RUNNER_OPTS="-Xmx512m -XX:MaxPermSize=512m"

全部-现在工作。

The first export line: will get Jenkins going without PermGen error, the 2nd
line will make Gradle going when Jenkins calls Gradle script (via a another
wrapper script for ex. .sh/etc), third line makes “sonar-runner” command to
work fine (otherwise, I was getting an error for PermGen after “Initialize
Hibernate”… line during sonar-runner command’s output). You run sonar-runner
command in the workspace where you have compiled java, reports related to
static code analysis tools (pmd/checkstyle/findbugs) and other code coverage
reports (jacoco/cobertura). Workspace should have “sonar-project.properties”
file. Look for SonarQube help pages about this file and what all variables it
contains for a project.

所有这些选项都记录在这里： http

如果使用的是Java 7，则在这里记录：
