1. Modify the foundationdb.conf file.
   1. Open /etc/foundationdb/foundationdb.conf.

      vim /etc/foundationdb/foundationdb.conf 

   2. Press i to enter the insert mode, locate the public-address configuration item under [fdbserver], and change the value to Local IP address:$ID.

      For example, if the IP address of the Meta node is 192.168.65.10, set this item to 192.168.65.10:$ID.
