couchbase: epmd:节点名称已占用couchbase babysitter_of_ns_1

Question

Sep 15 12:45:36 build64 epmd: epmd: node name already occupied babysitter_of_ns_1
Sep 15 12:46:29 build64 epmd: epmd: Disallowed KILL_REQ, live nodes
Sep 15 12:50:58 build64 epmd: epmd: got KILL_REQ - terminates normal
Sep 15 13:03:29 build64 epmd: epmd: Disallowed KILL_REQ, live nodes
Sep 15 13:04:48 build64 epmd: epmd: got KILL_REQ - terminates normal
Sep 15 13:06:08 build64 epmd: epmd: Disallowed KILL_REQ, live nodes

但

$ sudo /opt/couchbase/bin/epmd -kill 
Killing not allowed - living nodes in database.

$ sudo /opt/couchbase/bin/epmd -names
epmd: up and running on port 4369 with data:
name babysitter_of_ns_1 at port 21100

之后

# /etc/init.d/couchbase-server stop
Stopping couchbase-serverps
# ps auxwww|egrep "epm|couch"
#

如何找出启动不起来的原因？其他节点现在处于“挂起”状态。

PS可能是第二次尝试启动"node name已占用couchbase babysitter_of_ns_1“，而主要错误是"Disallowed KILL_REQ，live nodes”

PPS通常，集群中其他节点上的节点显示为down，其他节点处于"pend“状态，并且出现故障的节点上的端口8091没有响应，尽管在某些东西启动之后。

听起来您有一个部分Couchbase实例仍在运行。我建议终止Couchbase拥有的所有进程，然后尝试重新启动。以root用户身份：

killall -u couchbase
ps -u couchbase
<verify no processes remain>
/etc/init.d/couchbase-server start
