每次成功安装 Open vSwitch 并重新启动后，我都会收到以下错误。ovs-vsctl: unix:/usr/local/var/run/openvswitch/db.sock: 数据库连接失败（没有这样的文件或目录）。有谁知道为什么 db.sock 文件丢失了？

在 Fedora 22 上，这对我有用：

sudo /usr/share/openvswitch/scripts/ovs-ctl start

再次启动ovsdb，即可连接成功。

#!/bin/bash 
ovsdb-server --remote=punix:/usr/local/var/run/openvswitch/db.sock \
                     --remote=db:Open_vSwitch,Open_vSwitch,manager_options \
                     --private-key=db:Open_vSwitch,SSL,private_key \
                     --certificate=db:Open_vSwitch,SSL,certificate \
                     --bootstrap-ca-cert=db:Open_vSwitch,SSL,ca_cert \
                     --pidfile --detach
ovs-vsctl --no-wait init
ovs-vswitchd --pidfile --detach

它正在查找文件的事实/usr/local表明您正在运行本地构建的 Open vSwitch 版本。db.sock 文件的默认路径是/var/run/openvswitch/db.sock.

在配置 Open vSwitch 构建时，可以通过以下方式避免此问题：

./configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc

在 OEL7.5 上，我遇到了类似的错误。我的解决方法是将服务设置为在重新启动时启动：

[root@controller-oel7-5 ~]# ovs-vsctl add-br br0
