领事服务器无法重新加入集群，几秒钟后离开
Consul server fails to rejoin the cluster, leaves after few seconds
我的案例的简短概述：
最初我有一个简单的 运行 consul 集群，其中包含一个服务器 (server1) 和多个客户端。这是我的 server1.json 配置文件：
{
"server": true,
"datacenter": "dc1",
"data_dir": "/opt/consul",
"bind_addr": "0.0.0.0",
"client_addr":"0.0.0.0",
"bootstrap_expect": 3,
"ui": true,
"retry_join": ["provider=aws tag_key=Function tag_value=consul-server"],
"encrypt":"WT2T9..."
}
注意：bootstrap_expect原来是=1，我加新服务器的时候改成了3。
出于某些测试目的，我想向集群中再添加两台服务器。
所以我一台一台地配置和添加服务器。一切都按预期工作，我可以确认我的集群现在有 3 个服务器，其中两个新服务器（server1 和 server2）是跟随者。
这是我的 server2.json 配置文件：
server3 的配置文件看起来一样。
现在，当我的集群 运行 时，出于测试目的，我停止了作为领导者的 server1 的服务。结果，选出了新的leader。
consul members命令显示：
Node Address Status Type Build Protocol DC Segment
server2 xx.xx.x.xx1:8301 alive server 1.9.3 2 dc1 <all>
server1 xx.xx.x.xx2:8301 left server 1.8.3 2 dc1 <all>
server3 xx.xx.x.xx3:8301 alive server 1.9.3 2 dc1 <all>
看起来不错！ Server1已离开。
现在我想将 server1 带回我的集群。
所以我重新启动了 server1 的 consul.service，我希望它能重新加入集群。
并加入了它，但几秒钟后它失败并离开了集群。
这里有一些输出：

正如您从第二个输出中看到的那样，server1 实际上正在加入集群，但随后发生了一些事情并离开了集群。
panic: failed to decode request: invalid config entry kind: service-intentions
我尝试以不同的方式修改配置文件并重新启动 consul server1 --> 没有成功。
最后我清空了 consul data_dir 并重新启动了 server1 --> 但没有成功。
有没有人经历过这样的事情，可以在这里支持一下？
如果您查看提供的“紧急”行上方的几行，您会看到：
[WARN] agent.server.raft：无法获取以前的日志：previous-index=93400 last-index=93262 error="找不到日志"。
日志复制似乎有问题。当前领导者无法将日志复制到新的追随者。
虽然我猜这可能有多种原因，但一个可能的问题可能是 consul 的版本。据我从您的 consul members 命令中看到， server1 的版本比您的领导者的版本旧（无论是 server2 还是 server3）。
Node Address Status Type Build Protocol DC Segment
server2 xx.xx.x.xx1:8301 alive server 1.9.3 2 dc1 <all>
server1 xx.xx.x.xx2:8301 left server 1.8.3 2 dc1 <all>
server3 xx.xx.x.xx3:8301 alive server 1.9.3 2 dc1 <all>
尝试从有问题的节点（在您的情况下为 server1）中删除 consul 二进制文件，并将其替换为新版本。之后重启领事。
我的案例的简短概述：
最初我有一个简单的 运行 consul 集群，其中包含一个服务器 (server1) 和多个客户端。这是我的 server1.json 配置文件：
{
"server": true,
"datacenter": "dc1",

"bootstrap_expect": 3,
"ui": true,
"retry_join": ["provider=aws tag_key=Function tag_value=consul-server"],
"encrypt":"WT2T9..."
}
注意：bootstrap_expect原来是=1，我加新服务器的时候改成了3。
出于某些测试目的，我想向集群中再添加两台服务器。
所以我一台一台地配置和添加服务器。一切都按预期工作，我可以确认我的集群现在有 3 个服务器，其中两个新服务器（server1 和 server2）是跟随者。

现在我想将 server1 带回我的集群。

正如您从第二个输出中看到的那样，server1 实际上正在加入集群，但随后发生了一些事情并离开了集群。
panic: failed to decode request: invalid config entry kind: service-intentions
我尝试以不同的方式修改配置文件并重新启动 consul server1 --> 没有成功。
最后我清空了 consul data_dir 并重新启动了 server1 --> 但没有成功。
有没有人经历过这样的事情，可以在这里支持一下？
如果您查看提供的“紧急”行上方的几行，您会看到：
[WARN] agent.server.raft：无法获取以前的日志：previous-index=93400 last-index=93262 error="找不到日志"。
日志复制似乎有问题。当前领导者无法将日志复制到新的追随者。
虽然我猜这可能有多种原因，但一个可能的问题可能是 consul 的版本。据我从您的 consul members 命令中看到， server1 的版本比您的领导者的版本旧（无论是 server2 还是 server3）。
Node Address Status Type Build Protocol DC Segment
server2 xx.xx.x.xx1:8301 alive server 1.9.3 2 dc1 <all>
server1 xx.xx.x.xx2:8301 left server 1.8.3 2 dc1 <all>
server3 xx.xx.x.xx3:8301 alive server 1.9.3 2 dc1 <all>
尝试从有问题的节点（在您的情况下为 server1）中删除 consul 二进制文件，并将其替换为新版本。之后重启领事。
