我正在尝试在 Ubuntu 主机上使用 kolla-ansible (7.0.0) 部署 OpenStack Queens,如下所示官方指南。
成功后bootstrap-servers
,precheck
命令deploy
失败:

就是这样,两个 keepalived 实例都处于 FAULT 状态,IP 地址未在任何虚拟机上激活。
我经历了这个问题和答案,即使日志文件中没有错误消息:
- keepalived_virtual_router_id已更改并且是唯一的
- 我
kolla-genpwd
再次运行。我确认已keepalived_password
设置/etc/kolla/passwords.yml
kolla_internal_vip_address
可从 访问network_interface
。该接口上的主 IP 位于同一网络中。我可以手动设置附加 IP 地址,并且它可以正常工作。kolla-ansible prechecks
通行证- selinux 在 Ubuntu 上未处于活动状态
在虚拟机管理程序方面,我尝试启用Promiscuous mode
该接口的端口组。但没有什么效果。
答案1
因此,在裸机上遇到同样的问题后,我深入研究了这个问题。结果发现问题不是出在 keepalived 上,而是出在 haproxy 容器上。
haproxy 容器不断重启,因为 haproxy 是使用命令行参数启动的-W
,而该参数在容器中附带的 haproxy 版本中不存在。

-d enters debug mode ; -db only disables background mode.
-dM[<byte>] poisons memory with <byte> (defaults to 0x50)
-V enters verbose mode (disables quiet mode)
-D goes daemon ; -C changes to <dir> before loading files.
-q quiet mode : don't display messages
-c check mode : only check config files and exit
-n sets the maximum total # of connections (2000)
-m limits the usable amount of memory (in MB)
-N sets the default, per-proxy maximum # of connections (2000)
-L set local peer name (default to hostname)
-p writes pids of all children to this file
-de disables epoll() usage even when available
-dp disables poll() usage even when available
-dS disables splice usage (broken on old kernels)
-dV disables SSL verify on servers side
-sf/-st [pid ]* finishes/terminates old pids.
因此,haproxy 容器不断重新启动。另一方面,keepalived 容器配置了 keepalived 的检查脚本,该脚本不断退出并出现错误:
Fri Feb 15 08:17:14 2019: /check_alive.sh exited with status 1
Keepalived_vrrp[12]: /check_alive.sh exited with status 1
这个检查脚本很简单,它通过一个socket文件来检查haproxy的状态:
#!/bin/bash
# This will return 0 when it successfully talks to the haproxy daemon via the socket
# Failures return 1
echo "show info" | socat unix-connect:/var/lib/kolla/haproxy/haproxy.sock stdio > /dev/null
所以...只要使用无效参数调用 haproxy 并且不启动,keepalived 就会保持FAULT
状态,不会出现浮动 IP。
使用grep -R "haproxy -W" *
我发现 haproxy 的命令行在文件中定义/usr/local/share/kolla-ansible/ansible/roles/haproxy/templates/haproxy.json.j2
。我-W
从命令行中删除了该参数,这导致 haproxy 正常启动并且 keepalived 更改为MASTER
配置浮动 IP 的状态。
已经有一个关于此问题的错误报告已在 Launchpad 上打开。评论中还有一个稍微不同的解决方案(更改同一个文件)。
当然,此修改将在文件更新时恢复。如果您遇到同样的问题,请登录 Launchpad 并标记该错误(于 2018-06-08 报告)对您有影响,以便优先处理并修复。
