elasticsearch5.4集群超时

sifangbobo,扩谱,妙语连珠

四个节点，有两个是新增加的节点，两个老节点间组成集群没有问题，新增加了两个节点，无论是四个组成集群

# --------------------------------- discovery ----------------------------------
#
# pass an initial list of hosts to perform discovery when new node is started:
# the default list of hosts is ["127.0.0.1", "[::1]"]
#
discovery.zen.ping.unicast.hosts: ["10.96.91.208","10.96.91.209","10.96.91.210","10.96.91.211"]
#
# prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
#
discovery.zen.minimum_master_nodes: 3
#
# for more information, consult the zen discovery module documentation.
#

 

还是两个节点集群(新旧搭配)

# --------------------------------- discovery ----------------------------------
#
# pass an initial list of hosts to perform discovery when new node is started:
# the default list of hosts is ["127.0.0.1", "[::1]"]
#
discovery.zen.ping.unicast.hosts: ["10.96.91.208","10.96.91.210"]
#
# prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
#
discovery.zen.minimum_master_nodes: 2
#

查看日志，可以发现是网络问题。
排查网络
网卡的网络配置

cd /etc/sysconfig/network/
more ifcfg-eth0

　　


网络路由配置

more routes

 

网关配置

more /etc/resolv.conf

 



这些配置四台服务器基本都是一样的。所以不是配置问题
继续检查ping 和 traceroute
ping没有问题
traceroute显示不一样，发现有了一个空跳。怀疑是防火墙的问题

查看防火墙的状态

chkconfig --list|grep fire

 

关闭防火墙

cd /etc/init.d/
./susefirewall2_setup stop
./susefirewall2_init stop

 


开机关闭防火墙

chkconfig susefirewall2_setup off
chkconfig susefirewall2_init off

 


至此，解决问题
