Preface

This pit can be big or small. To summarize, this problem is generally caused by these three points:

1. 【Big Pit】The accessed console webpage is not added /naocs
2. No startup mode is specified, for example: MODE=standalone
3. Firewall issues

Docker install Nacos

docker pull nacos/nacos-server:1.4.1

docker run --name nacos \
  --restart=always \
  -e MODE=standalone \
  -p 8848:8848 \
  -d \
  nacos/nacos-server:1.4.1

Visit URL:http://192.168.136.128:8848/nacos

If this interface can appear, you don't need to read the following content.​ 

It should be noted that the accessed web page requires[IP]:[Port]/nacos not added /nacos It is very likely that a 404 page will appear. This is the reason why 90% of friends on the Internet report errors when accessing.

BUG

1. The accessed console webpage is not added /naocs

This point was discussed above

You can take a look at this screenshot. The editor only realized this after reading this article.

2. No startup method specified

-e MODE=standalone 

3. Firewall issues

Query the ports that have been opened to the outside world

netstat -anp

Check whether the specified port is open

firewall-cmd --query-port=8848/tcp

Add the specified ports that need to be opened:

firewall-cmd --add-port=8848/tcp --permanent

Reload the added port:

firewall-cmd --reload

Check whether the specified port is opened successfully:

firewall-cmd --query-port=8848/tcp

The article ends here. If you have any questions, you can point them out in the comment area~

I hope to work hard with the big guys and see you all at the top
