1）啟動虛擬機報錯，錯誤下 [root@vagrant ubuntu]# vagrant up Bringing machine 'default' up with 'virtualbox' provider... An action 'up' was attempted on the machine 'default', but another process is already executing an action on the machine. Vagrant locks each machine for access by only one process at a time. Please wait until the other Vagrant process finishes modifying this machine, then try again. If you believe this message is in error, please check the process listing for any "ruby" or "vagrant" processes and kill them. Then try again. 介紹：這是由于執行vagrant up 啟動虛擬機的時候，以外中斷導致的，我們必須通過kill殺掉響應的進程（這里一定要看清楚，別kill錯咯） [root@vagrant ubuntu]# ps -ef|grep vagrant avahi 19833 1 0 10:30 ? 00:00:00 avahi-daemon: running [vagrant.local] root 66336 5220 0 15:23 pts/1 00:00:00 bash /usr/bin/vagrant up root 66337 66336 0 15:23 pts/1 00:00:00 /opt/vagrant/bin/vagrant up root 66342 66337 0 15:23 pts/1 00:00:01 ruby /opt/vagrant/embedded/gems/gems/vagrant-1.9.2/bin/vagrant up root 67956 5220 0 15:39 pts/1 00:00:00 grep --color=auto vagrant [root@vagrant ubuntu]# kill -9 66342 2
