问题
当我运行mininet时，出现以下问题：
***Creating network ***Adding controller ***Adding hosts: h1 h2 h3 h4 h5 ***Adding switches: s1 ***Adding links: (h1, s1) (h2, s1) (h3, s1) (h4, s1) (h5, s1) ***Configuring hosts h1 h2 h3 h4 h5 ***Starting controller Cannot find required executable controller. Please make sure that it is installed and available in your $PATH: (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin)
解决
运行以下命令：
sudo ln /usr/bin/ovs-controller /usr/bin/controller
即可解决。
