Use Docker-compose to build a Nacos cluster
Download the NACOS cluster environment
Download docker-compose from Nacos 1.4.0: github.com/nacos-group… (I use Nacos version 1.4.0)
Then use Xftp to put the decompressed folder into Linux.
Create a docker – compose. Yml
Note: please delete the comment ！！！！！！ when writing to docker-comemess. yml
cd /usr/local/myLocal/nacos-docker-master/example
vim docker-compose.yml
