apache - 尝试将 Apache Tomcat 端口从 8080 更改为 80 时出现内存错误

Question

我试图让我在 VPS 上安装的 Tomcat 在端口 80 而不是 8080 上运行，但是当我在我的 Tomcat 目录中编辑 server.xml 文件的设置并尝试重新启动 Tomcat 时，我'我收到此错误:

Jan 23, 2012 9:55:46 AM org.apache.coyote.http11.Http11Protocol init SEVERE: Error initializing endpoint java.net.SocketException: Cannot allocate memory at java.net.PlainSocketImpl.socketBind(Native Method) at java.net.AbstractPlainSocketImpl.bind(AbstractPlainSocketImpl.java:353) at java.net.ServerSocket.bind(ServerSocket.java:336) at java.net.ServerSocket.(ServerSocket.java:202) at java.net.ServerSocket.(ServerSocket.java:158) at org.apache.tomcat.util.net.DefaultServerSocketFactory.createSocket(DefaultServerSocketFactory.java:50) at org.apache.tomcat.util.net.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.net.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)

不太确定那是什么意思...这是否意味着我没有足够的内存？是否有其他方法可以让 Tomcat 在端口 80 上运行？

编辑:这是我输入 free -m 时的输出:

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

Answer 1

我在 OpenVZ 上使用 authbind 在端口 80 上运行的 Tomcat 遇到了同样的问题。我通过从 OpenJDK 切换到 Sun Java 解决了这个问题。
