"Out of Memory!" - 启动从本机程序包安装的SonarQube时Debian 8出错

Question

我在拥有4GB RAM的VM上全新安装了Debian 8.我安装了SonarQube(使用本机包).当我尝试使用提供的脚本启动时,日志会显示以下内容:

--> Wrapper Started as Daemon
Launching a JVM...
JVM exited while loading the application.
GC Warning: Out of Memory!  Returning NIL!
Exception in thread "main" GC Warning: Out of Memory!  Returning NIL!
java.lang.OutOfMemoryError
*** Got java.lang.NoClassDefFoundError: gnu.gcj.runtime.NameFinder while trying to print stack trace.
JVM Restarts disabled.  Shutting down.
<-- Wrapper Stopped

我尝试在启动脚本中增加-Xmx和-Xms值无效.

Answer 1

从您的日志中,您似乎使用的是默认的java aka gnu.gcj.

你应该安装openjdk7或openjdk8

您可以通过编辑wrapper.java.command属性在$ SONAR_HOME/conf/wrapper.conf中选择适当的JVM,即

# To use Java 7
wrapper.java.command=/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java

# To use Java 8
wrapper.java.command=/usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java
