启动influxdb--node1节点操作
systemctl start influxdb-cluster@1 influxdb-cluster@2
systemctl status influxdb-cluster@1 influxdb-cluster@2
systemctl enable influxdb-cluster@1 influxdb-cluster@2
启动influxdb--node2节点操作
systemctl start influxdb-cluster@3 influxdb-cluster@4
systemctl status influxdb-cluster@3 influxdb-cluster@4
systemctl enable influxdb-cluster@3 influxdb-cluster@4
所有节点创建用户
influx -port 8086
CREATE USER admin with PASSWORD ‘****‘ WITH ALL PRIVILEGES
influx -port 8087
CREATE USER admin with PASSWORD ‘*****‘ WITH ALL PRIVILEGES
以下操作请在influxdb-master1节点上操作
