试图改变的Apache Tomcat端口从8080到80时内存错误

本文介绍了试图改变的Apache Tomcat端口从8080到80时内存错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我试图让我安装Tomcat上VPS到端口80上，而不是8080上运行，但是当我编辑我的Tomcat目录下的server.xml文件中的设置，并尝试重新启动Tomcat，我m到处这个错误：

不能确定这意味着什么？这是否意味着我没有足够的内存？有没有其他的方法让Tomcat能够在80端口上运行？

编辑：这是输出，当我在自由-m类型：

共免费使用共享缓冲区高速缓存纪念品：1024 748 275 0 0 0 - / +缓冲区/缓存：748 275交换：0 0 0

解决方案

我得到了同样的问题在Tomcat中使用authbind到80端口上。我解决它由OpenJDK的切换到的Sun Java运行OpenVZ的。

I'm trying to get my installation of Tomcat on a VPS to run on port 80 instead of 8080, but when I edit the settings for the server.xml file in my Tomcat directory, and try to restart Tomcat, I'm getting this error:

Jan 23, 2012 9:55:46 AM org.apache.coyote.http11.Http11Protocol init SEVERE: Error initializing endpoint java.SocketException: Cannot allocate memory at java.PlainSocketImpl.socketBind(Native Method) at java.AbstractPlainSocketImpl.bind(AbstractPlainSocketImpl.java:353) at java.ServerSocket.bind(ServerSocket.java:336) at java.ServerSocket.(ServerSocket.java:202) at java.ServerSocket.(ServerSocket.java:158) at org.apache.tomcat.util.DefaultServerSocketFactory.createSocket(DefaultServerSocketFactory.java:50) at org.apache.tomcat.util.JIoEndpoint.init(JIoEndpoint.java:538) at org.apache.coyote.http11.Http11Protocol.init(Http11Protocol.java:176) at org.apache.catalina.connector.Connector.initialize(Connector.java:1014) at org.apache.catalina.core.StandardService.initialize(StandardService.java:680) at org.apache.catalina.core.StandardServer.initialize(StandardServer.java:795) at org.apache.catalina.startup.Catalina.load(Catalina.java:524) at org.apache.catalina.startup.Catalina.load(Catalina.java:548) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at org.apache.catalina.startup.Bootstrap.load(Bootstrap.java:261) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:413) Jan 23, 2012 9:55:46 AM org.apache.catalina.startup.Catalina load SEVERE: Catalina.start LifecycleException: Protocol handler initialization failed: java.SocketException: Cannot allocate memory at org.apache.catalina.connector.Connector.initialize(Connector.java:1016) at org.apache.catalina.core.StandardService.initialize(StandardService.java:680) at org.apache.catalina.core.StandardServer.initialize(StandardServer.java:795) at org.apache.catalina.startup.Catalina.load(Catalina.java:524) at org.apache.catalina.startup.Catalina.load(Catalina.java:548) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:616) at org.apache.catalina.startup.Bootstrap.load(Bootstrap.java:261) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:413)

Not really sure what that means... Does it mean I don't have enough memory? Are there alternative ways to get Tomcat to run on port 80?

Edit: Here is the output when I type in free -m:

total used free shared buffers cached Mem: 1024 748 275 0 0 0 -/+ buffers/cache: 748 275 Swap: 0 0 0

解决方案

I got the same issue with Tomcat on OpenVZ using authbind to run on port 80. I solved it by switching from OpenJDK to Sun Java.
