consul - 服务器重启后如何重新加入consul客户端到服务器？

Question

我已经启动了服务器(单节点)。并加入客户端。

# consul members
Node                   Address             Status  Type    Build  Protocol  DC
v-ansible              172.16.10.11:8301   alive   server  0.5.2  2         dc1
v-php-cron             172.16.10.217:8301  alive   client  0.5.2  2         dc1

然后我重新启动服务器。在服务器上我看到:

# consul members
Node                   Address            Status  Type    Build  Protocol  DC
v-ansible              172.16.10.11:8301  alive   server  0.5.2  2         dc1

在客户端:

# consul members
Node                   Address             Status  Type    Build  Protocol  DC
v-php-cron             172.16.10.217:8301  alive   client  0.5.2  2         dc1
v-ansible              172.16.10.11:8301   left    server  0.5.2  2         dc1

客户端日志中:

2015/11/05 17:35:05 [INFO] consul: adding server v-ansible (Addr: 172.16.10.11:8300) (DC: dc1)
2015/11/05 17:38:14 [INFO] serf: EventMemberLeave: v-ansible 172.16.10.11
2015/11/05 17:38:14 [INFO] consul: removing server v-ansible (Addr: 172.16.10.11:8300) (DC: dc1)
2015/11/05 17:39:45 [ERR] agent: failed to sync remote state: No known Consul servers
2015/11/05 17:40:11 [ERR] agent: failed to sync remote state: No known Consul servers
2015/11/05 17:40:30 [ERR] agent: failed to sync remote state: No known Consul servers

为什么服务器停留在左侧状态？如何让客户端自动重新加入服务器？

skip_leave_on_interrupt 选项解决了我的问题。如果skip_leave_on_interrupt=True(默认)，服务器在重新启动期间向集群发送LEAVE
