13.9. 单应用程序模式

过程 13.9. 设置单应用程序模式

1. 使用以下内容创建以下文件：
   • /usr/bin/redhat-kiosk

     #!/bin/sh
     
     if [ ! -e ~/.local/bin/redhat-kiosk ]; then
         mkdir -p ~/.local/bin ~/.config
         cat > ~/.local/bin/redhat-kiosk << EOF
     #!/bin/sh
     # This script is located in ~/.local/bin.
     # It's provided as an example script to show how
     # the kiosk session works.  At the moment, the script
     # just starts a text editor open to itself, but it
     # should get customized to instead start a full screen
     # application designed for the kiosk deployment.
     # The "while true" bit just makes sure the application gets
     # restarted if it dies for whatever reason.
     
     while true; do
         gedit ~/.local/bin/redhat-kiosk
     done
     
     EOF
     
         chmod +x ~/.local/bin/redhat-kiosk
         touch ~/.config/gnome-initial-setup-done
     fi
     
     exec ~/.local/bin/redhat-kiosk "$@"

     重要
     /usr/bin/redhat-kiosk 文件必须是可执行的。
     将 gedit ~/.local/bin/redhat-kiosk 代码替换为您要在 kiosk 会话中执行的命令。这个示例启动了一个为 kiosk 部署而设计的全屏应用程序，名为 http://mine-kios-web-app ：

     [...]
     while true; do
         firefox --kiosk http://mine-kios-web-app
     done
     [...]

3. 为 kiosk 会话创建一个单独的用户，并选择 Kiosk 作为 kiosk 会话的用户的会话类型。
