我做了什么？

下载正确版本的Jre/jdk。

rpm -ivh jdk-7u15-linux-x64.rpm
rpm -ivh lolo.rpm  (Its jre-7u13-linux-x64 rpm file)
cd source
sh run.sh

我做错了什么？

在 centOS 6.x 上运行

答案1

尝试以“tar.gz”格式下载 JDK。

将 tar.gz 的内容解压到您想要安装 Java 的文件夹中，例如：

tar xvf myJava7.tar.gz

然后，设置您的 JAVA_HOME 变量并更新引用，要更新您的引用，请执行以下操作：

sudo update-alternatives --install "/usr/bin/javac" "javac" "/path/where/i/extracted/usr/lib/jvm/java7/bin/javac" 1

sudo update-alternatives --config javac

当您使用 tar 文件时，您可以指定并使 Java 或任何其他组件的安装更加灵活。

此致。

答案2

您试图为 Java VM 的堆分配比可用内存更多的内存。查看 shell 脚本并查看传递给 Java 的参数是什么。

要寻找的参数是：

  • -Xms – 最小
  • -Xmx – 最大值

答案3

您应该使用以下命令运行 JVM：

-XX:MaxHeapSize=256m -Xmx512m

您可以随意更改这两个数字，但一定要确保堆大小很大。

答案4

[root@centos57 ~]# echo $JAVA_HOME
/java/jdk1.7.0_11

同时运行：

java -version

查看已安装的内容。

您应该会看到类似的输出 - 如果没有，则表示它未识别出所引用的 JDK。此外，如果_13显示在 之前，则_15需要移动顺序。

如果所有这些都失败了，请运行：

yum remove java

并重新安装。
