实验总结

安装ODL遇到的问题

• 两种版本的ODL（Carbon、Beryllium）不能同时存在，否则访问其网页时会报404
• Carbon版本安装插件时，将命令从pdf直接复制到linux上时，flow-services中间的-会消失

安装ryu时遇到的问题

1.步骤（4）下载超时

报错：

ERROR: Exception: Traceback (most recent call last)

解决方法：网络问题，建议更换网络或连热点

2.步骤（6）ryu版本查看问题

报错：

usage: ryu [-h] [--config-dir DIR] [--config-file PATH] [--version] subcommand ...

positional arguments:
  subcommand          [run|of-config-cli|rpc-cli]
  subcommand_args     subcommand specific arguments

optional arguments:
  -h, --help          show this help message and exit
  --config-dir DIR    Path to a config directory to pull `*.conf` files from. This file set is
                      sorted, so as to provide a predictable parse order if individual options are
                      over-ridden. The set is parsed after the file(s) specified via previous
                      --config-file, arguments hence over-ridden options in the directory take
                      precedence. This option must be set from the command-line.
  --config-file PATH  Path to a config file to use. Multiple config files can be specified, with
                      values in later files taking precedence. Defaults to None. This option must be
                      set from the command-line.
  --version           show program's version number and exit
Unknown subcommand –version

解决方法：正确写法应为 ryu --version pdf上 ryu –version 中-仅一个，且不是英文格式
