如何从 Eclipse 以超级用户身份运行我的应用程序? [英] How do I run my application as superuser from Eclipse?

问题描述

当我尝试从 Eclipse 运行我的服务器应用程序时遇到错误.错误是java.net.BindException:权限被拒绝.我认为这是因为我使用端口 443 来设置 SSL 连接.如果我使用 java 和 sudo 在命令行上运行我的代码，我可以解决这个问题.有没有办法设置 Eclipse，以便当我点击运行按钮时，我的应用程序使用 sudo 执行?

解决方案

您可以按照以下步骤以超级用户身份编译/调试应用程序.

1. 重命名您的 Java 应用程序

   sudo mv/usr/lib/jvm/java-6-openjdk/jre/bin/java/usr/lib/jvm/java-6-openjdk/jre/bin/java.ori

2. 创建以下脚本并将其存储为/usr/lib/jvm/java-6-openjdk/jre/bin/java

   <块引用>

   #!/bin/bash# 文件:/usr/lib/jvm/java-6-openjdk/jre/bin/java# descr:jdk 的启动器.以 root 身份运行 jdk 时# cmd-line-arg "--run-as-root" 被指定.#jre="/usr/lib/jvm/java-6-openjdk/jre/bin/java.ori"run_as_root=false参数=# 过滤命令行参数对于 "$@" 中的 arg做案例$arg"在--run-as-root) run_as_root=true;;*) args="$args $arg";;esac完毕# 删除前导空格args=$(echo $args | sed -e 's/^[ 	]*//')如果 $run_as_root然后echo "警告:以 root 身份运行！"gksu "$jre $args"别的$jre $args菲

3. 更改权限以使其可执行

   sudo chmod 0755/usr/lib/jvm/java-6-openjdk/jre/bin/java

4. 启动日食

5. 转到窗口->首选项->Java->已安装的JRE
6. 将 java-6-openjdk 复制到 java-6-openjdk-root
7. 编辑 JRE 并添加--run-as-root"作为默认 VM 参数

要以 root 身份运行项目，您需要执行以下步骤:

1. 转到项目->属性->Java构建路径
2. 双击 JRE 系统库并在备用 JRE 中选择java-6-openjdk-root"

I'm running in to an error when I try to run my server application from Eclipse. The error is java.net.BindException: Permission denied. I think this is because I am using port 443 to set up an SSL connection. I can get around this problem if I run my code on the command line using java and sudo. Is there a way to set up Eclipse so that when I hit the run button, my application is executed with sudo?

解决方案

You can follow these steps to compile/debug applications as superuser.

1. Rename your java-application

   sudo mv /usr/lib/jvm/java-6-openjdk/jre/bin/java /usr/lib/jvm/java-6-openjdk/jre/bin/java.ori

2. Create following script and store it as /usr/lib/jvm/java-6-openjdk/jre/bin/java

   #!/bin/bash
   # file:  /usr/lib/jvm/java-6-openjdk/jre/bin/java
   # descr: Starter for jdk. Runs jdk as root when 
   #        cmd-line-arg "--run-as-root" is specified.
   #
   jre="/usr/lib/jvm/java-6-openjdk/jre/bin/java.ori"
   run_as_root=false
   args=
   
   # Filter command-line argument
   for arg in "$@"
   do
     case "$arg" in
     --run-as-root)  run_as_root=true
                     ;;
     *)              args="$args $arg"
                     ;;
   
     esac
   done
   
   # Remove leading whitespaces
   args=$(echo $args | sed -e 's/^[ 	]*//')
   
   if $run_as_root
   then
     echo "WARNING: Running as root!"
     gksu "$jre $args"
   else
     $jre $args
   fi
   

3. Change the permissions to make it executable

   sudo chmod 0755 /usr/lib/jvm/java-6-openjdk/jre/bin/java

4. Startup eclipse

5. Go to Window->Preferences->Java->Installed JREs
6. Duplicate java-6-openjdk to java-6-openjdk-root
7. Edit JRE and add "--run-as-root" as Default VM Argument

To run projects as root you need to follow these steps:

1. Go to Project->Properties->Java Build Path
2. Double-Click the JRE System Library and choose in Alternate JRE "java-6-openjdk-root"
