Answer 1

不久前，我发现了这个臭虫在笑板上，它有一个解决办法:停止Apache服务器。当时，我显然不是在运行Apache。本周，我再次尝试启动Micro堆栈服务，并得到了同样的错误消息。然后，我检查了一下，Apache在我的机器上运行。我停止了Apache服务，并且微堆栈服务正确启动：

sudo service apache2 stop

Answer 2

执行journalctl -xe并查看是否在那里找到错误的详细信息。对我来说，我收到了一条错误消息

已在使用的地址0.0.0.0:9292

事实证明，在我的例子中，它是emacs：

ss -lnp|grep :9292
tcp LISTEN 0 5 127.0.0.1:9292 0.0.0.0:* users:(("emacs",pid=126434,fd=15))       

在我停止了emacs之后，nginx就开始了，没有问题。

Answer 3

我也有同样的问题，但在microstack.ovs.vswitchd上

为了解决这个问题，我要安装开开关开关-dpdk。

您的解决方案可能是安装nginx。
