提示：LXC WEB Panel是用flask框架研发，所以依赖python-flask这个包，当然也可以用pip去下载这个也是可以的
pip安装flask，首先要安装python-pip

You are using pip version 8.1.2, however version 20.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
[root@docker_node1 ~]# pip list|grep "Flask"
Flask (1.1.2)
You are using pip version 8.1.2, however version 20.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

提示：可以看到flask已经安装，版本是1.1.2
2、安装debootstrap

[root@docker_node1 ~]#
提示：在创建ubuntu容器时，需要依赖debootstrap;
3、安装LXC组件
请参考https://www.cnblogs.com/qiuhom-1874/p/12901493.html；如果你的主机已经安装这一步可以跳过
4、克隆LXC WEB Panel项目到本地
[root@docker_node1 ~]# git clone https://github.com/lxc-webpanel/LXC-Web-Panel.git Cloning into 'LXC-Web-Panel'... remote: Enumerating objects: 243, done. remote: Total 243 (delta 0), reused 0 (delta 0), pack-reused 243 Receiving objects: 100% (243/243), 198.33 KiB | 205.00 KiB/s, done. Resolving deltas: 100% (108/108), done. [root@docker_node1 ~]# ls LXC-Web-Panel [root@docker_node1 ~]# cd LXC-Web-Panel/ [root@docker_node1 LXC-Web-Panel]#
5、启动LXC WEB Panel
提示：成功启动LXC WEB Panel后，会像上图一样，提示我们访问本机的5000端口；
到此LXC WEB Panel就搭建好了，接下来我们就可以访问5000端口，登录LXC WEB Panel来管理我们的LXC容器了；
提示：默认用户名和密码是admin
提示：登录LXC WEB Panel后，在没有容器的情况下会提示我们创建容器，这里需要注意的是，如果你的主机上没有虚拟的网桥，要创建网桥，在新建容器，否则新建的容器无法启动；
新建网桥请参考https://www.cnblogs.com/qiuhom-1874/p/12901493.html；本人用图形界面去创建网络会报错，不知道哪里的原因；只好手动去Linux shell终端上创建好了；
创建好网桥后，再来启动刚才创建好的容器，就可以正常启动了
提示：可以看到我们创建了网桥后就可以正常启动容器了；如果你主机上有其他网桥也是可以的，我们可以编辑u1，把你主机上有的网桥和类型对应起来，给定一个ip地址，然后启动就没有问题；如下所示
提示：link其他网络需要注意类型，上面docker0桥同virbr0都是虚拟网桥，所以类型是veth;这里还需要注意，如果类型填错了，会导致服务不可用，解决办法是删除/var/lib/lxc/对应容器的名的目录，然后重新启动 LXC WEB Penal；以上就是 LXC的图形管理工具LXC WEB Penal的简单管理，更多的管理可以自己搭建一个玩玩；
