jenkins自动部署war到tomcat 7应用服务器时很不稳定,经常出现错误:
| 1 2 3 4 5 6 7 | ERROR: Publisher hudson.plugins.deploy.DeployPublisher aborted due to exception org.codehaus.cargo.container.ContainerException: Failed to deploy [ /var/lib/jenkins/jobs/devel_auto_build_deploy/workspace/build/libs/reis .war] ... Caused by: org.codehaus.cargo.container.tomcat.internal.TomcatManagerException: FAIL - Encountered exception javax.management.RuntimeErrorException: Error invoking method check ... org.codehaus.cargo.container.tomcat.internal.TomcatManagerException: FAIL - Encountered exception javax.management.RuntimeErrorException: Error invoking method check ... |
tomcat日志可以看到如下异常:
堆空间内存不足| 1 | java.lang.OutOfMemoryError: Java heap space |
永久代内存不足
| 1 2 3 4 5 | SEVERE: Exception invoking method check java.lang.OutOfMemoryError: PermGen space ... Exception in thread "http-bio-8080-exec-38" java.lang.OutOfMemoryError: PermGen space OpenJDK 64-Bit Server VM warning: Exception java.lang.OutOfMemoryError occurred dispatching signal SIGTERM to handler- the VM may need to be forcibly terminated |
出现此问题的原因是tomcat默认配置的堆和非堆内存都太小了，需要调整如下JVM内存配置参数:
-
- -Xms
初始堆内存大小
-
- -Xmx
最大堆内存大,一般设置-Xms与-Xmx一样大小,根据应用类型和物理内存大小来决定二者的大小
-
- -Xmn或者-XX:NewSize
堆内存中年轻代的大小
-
- -XX:PermSize
永久代内存的初始大小
-
- -XX:MaxPermSize
永久代内存的最大值
一般设置这几个参数也就够了,debian系统上tomcat 7 设置JVM的内存参数要在配置文件/etc/default/tomcat7中的JAVA_OPTS参数中设置。
一个web app,服务器物理内存16G,其设置如下:
| 1 | JAVA_OPTS= "-Djava.awt.headless=true -Xmx5120m -Xms5120m -Xmn1024m -XX:PermSize=1024m -XX:MaxPermSize=1024m -XX:+UseConcMarkSweepGC" |
