Answer 2

Please make sure you are doing correct.

请确保您的操作正确。

To install the Linux RPM (self-extracting) file Follow these instructions:

要安装 Linux RPM（自解压）文件，请遵循以下说明：

Become the root user by running the su command and entering the super-user password. At the terminal: Type:
```
su
```
Enter the root password.
Change to the directory in which you want to install. Type:
```
cd <directory>
```
For example, to install the software in the /usr/java/ directory, Type:
```
cd /usr/java
```
Note about root access: To install Java in a system-wide location such as/usr/local, you must login as the root user to gain the necessary permissions. If you do not have root access, install Java in your home directory or a subdirectory for which you have write permissions.
Change the permission of the file you downloaded to be executable. Type:
```
chmod a+x jre-6u<version>-linux-i586-rpm.bin
```
Start the installation process. Type:
```
./jre-6u<version>-linux-i586-rpm.bin
```
The license agreement is displayed. Review the agreement. Press the spacebar to display the next page. At the end, enter yes to proceed with the installation.
The installation file creates and runs the file jre-6-linux-i586.rpm in the current directory.
RPM unpacking completes
Verify that the jre1.6.0_ sub-directory is listed under the current directory. Type:
```
ls
```
Verify the installation filename

通过运行 su 命令并输入超级用户密码成为 root 用户。在终端：输入：
```
su
```
输入根密码。
切换到要安装的目录。类型：
```
cd <directory>
```
例如，要在 /usr/java/ 目录中安装软件，请键入：
```
cd /usr/java
```
关于 root 访问的注意事项：要在系统范围的位置（例如 /usr/local）安装 Java，您必须以 root 用户身份登录以获得必要的权限。如果您没有 root 访问权限，请将 Java 安装在您的主目录或您具有写入权限的子目录中。
将您下载的文件的权限更改为可执行文件。类型：
```
chmod a+x jre-6u<version>-linux-i586-rpm.bin
```
开始安装过程。类型：
```
./jre-6u<version>-linux-i586-rpm.bin
```
显示许可协议。查看协议。按空格键显示下一页。最后，输入 yes 继续安装。
安装文件会在当前目录下创建并运行文件 jre-6-linux-i586.rpm。
RPM 解包完成
验证当前目录下是否列出了 jre1.6.0_ 子目录。类型：
```
ls
```
验证安装文件名
