我试图使用./stack.sh在Ubuntu 16.04 VM上运行devstack
+lib/etcd3:start_etcd3:61 sudo systemctl daemon-reload
+lib/etcd3:start_etcd3:62 sudo systemctl enable devstack@etcd.service
Created symlink from /etc/systemd/system/multi-user.target.wants/devstack@etcd.service to

Job for devstack@etcd.service failed because the control process exited with error code. See "systemctl status

我缺少什么？
答案 0 :(得分：1)
在一些研究人员询问Openstack论坛和devstack时，禁用etcd' in stack.sh'有助于解决这个问题。
步骤：
/opt/stack/devstack/stach.sh 评论以下行（您将在1035行左右找到它们）
# Start Services
# ==============
# Dstat
# -----
# A better kind of sysstat, with the top process per time slice
#start_dstat
# Etcd
# -----
# etcd is a distributed key value store that provides a reliable way
to store data across a cluster of machines
#if is_service_enabled etcd3; then
# start_etcd3
#fi
保存上述文件。
./unstack.sh ./stack.sh 答案 1 :(得分：0)
好吧，您只需在local.conf中添加以下内容：
disable_service etcd3
然后运行stack.sh。
