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
     [...]
     

   • /usr/share/applications/com.redhat.Kiosk.Script.desktop

     [Desktop Entry]
     Name=Kiosk
     Type=Application
     Exec=redhat-kiosk
     

   • /usr/share/applications/com.redhat.Kiosk.WindowManager.desktop

     [Desktop Entry]
     Type=Application
     Name=Mutter
     Comment=Window manager
     Exec=/usr/bin/mutter
     Categories=GNOME;GTK;Core;
     OnlyShowIn=GNOME;
     NoDisplay=true
     X-GNOME-Autostart-Phase=DisplayServer
     X-GNOME-Provides=windowmanager;
     X-GNOME-Autostart-Notify=true
     X-GNOME-AutoRestart=false
     X-GNOME-HiddenUnderSystemd=true
     

   • /usr/share/gnome-session/sessions/redhat-kiosk.session

     [GNOME Session]
     Name=Kiosk
     RequiredComponents=com.redhat.Kiosk.WindowManager;com.redhat.Kiosk.Script;
     

   • /usr/share/xsessions/com.redhat.Kiosk.desktop

     [Desktop Entry]
     Name=Kiosk
     Comment=Kiosk mode
     Exec=/usr/bin/gnome-session --session=redhat-kiosk
     DesktopNames=Red-Hat-Kiosk;GNOME;
     

2. 重启 GDM 服务：

   systemctl restart gdm.service

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。
