ES HA测试
HA测试¶
1. 找到主¶
root@master:~# curl master:9200/_cat/nodes?v ip heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name 192.168.2.21 13 89 0 0.06 0.08 0.02 mdi - slave1 192.168.2.20 15 59 2 1.90 1.85 1.74 mdi * master 192.168.2.22 12 98 0 0.13 0.21 0.08 mdi - slave2
2. 停止主¶
cmz@master:/opt$ ps axf|grep ela 6016 pts/1 S+ 0:00 | \_ grep --color=auto ela
3. 查看¶
cmz@master:/opt$ curl slave1:9200/_cat/nodes?v ip heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name 192.168.2.22 13 98 0 0.00 0.00 0.00 mdi * slave2 192.168.2.21 15 89 0 0.05 0.03 0.00 mdi - slave1 cmz@master:/opt$ curl slave2:9200/_cat/nodes?v ip heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name 192.168.2.22 14 98 1 0.00 0.00 0.00 mdi * slave2 192.168.2.21 15 89 0 0.05 0.03 0.00 mdi - slave1
故障后,master转移，HA了。
