Hi there!
Possible cause:
The network interface card (NIC) configuration is inconsistent with that in the configuration file.
Solution:
1. Check the installation log /var/log/Bigdata/elk/scriptlog/postinstall.log of FusionInsight Elk.
2. If the NIC used is different from the one configured in the configuration file, change the NIC in the configuration file etc/udev/rules.d/70-persistent-net.rulesficonfig to the actual one.
