I recently encountered a problem at work. The docker container could not access the host's redis, and the telent6379 port was blocked. After investigation, it was found that the server had a firewall enabled, and the firewall authorized access to port 6379 to the docker0 network card. The operation is as follows:
Additional knowledge: Docker starts the mysql container and an error occurs: Ports are not available: listen tcp 0.0.0.0:3306 The error screenshot is as follows This error is caused by the local port 3306 being occupied. It is likely that MySQL has been installed locally and the MySQL service has been started. Solution 1: Open the service, find the mysql service, stop it, or change the port Then execute the following command
As shown in the figure, the startup is successful Solution 2: Change port mapping
illustrate: -p 3309:3306: -p host port: container port, that is, map the host port 3309 to the container port 3306. When the host logs in to the container database, use the host port, such as 3309. The above solution to the problem that the docker container cannot access the host port is all the content that the editor shares with you. I hope it can give you a reference, and I also hope that you will support 123WORDPRESS.COM. You may also be interested in:
