elasticsearch5.4集羣超時

四個節點，有兩個是新增長的節點，兩個老節點間組成集羣沒有問題，新增長了兩個節點，不管是四個組成集羣

# --------------------------------- 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.
#

 

仍是兩個節點集羣(新舊搭配)

# --------------------------------- 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"]
#

查看日誌，能夠發現是網絡問題。
排查網絡
網卡的網絡配置

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

　　

網絡路由配置

more routes

 

網關配置

more /etc/resolv.conf

 

這些配置四臺服務器基本都是同樣的。因此不是配置問題
繼續檢查ping 和 traceroute
ping沒有問題
traceroute顯示不同，發現有了一個空跳。懷疑是防火牆的問題

查看防火牆的狀態

chkconfig --list|grep fire

 

關閉防火牆

cd /etc/init.d/
./SuSEfirewall2_setup stop
./SuSEfirewall2_init stop

 

開機關閉防火牆

chkconfig SuSEfirewall2_setup off
chkconfig SuSEfirewall2_init off

 

至此，解決問題
