Elasticsearch同步出现timed out when collecting data的解决办法

　　elasticsearch集群其中源es使用虚拟机CentOS搭建，新的node使用k8s搭建，同步速度慢

　　elsasticsearch同步慢，出现以下提示的解决版本

?

1	[ERROR][o.e.x.m.c.n.NodeStatsCollector] [9OfhjwS] collector [node_stats] timed out when collecting data

 　　

 

 　　修改配置文件

?

1	/etc/sysctl.conf

 　　增加以下两行

?

1 2	vm.max_map_count = 655360 vm.dirty_ratio = 10

 　　设置生效

?

1 2 3 4 5

# sysctl -p net.ipv6.conf.all.disable_ipv6 = 1 vm.max_map_count = 655360 vm.dirty_ratio = 10 vm.dirty_background_ratio = 5

 　　增加k8s配置文件的资源配置

　　完整配置文件如下

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59

 　　增加了资源配置

 

 　　重新应用配置文件
