As shown in the title, using the docker container installed by centos, the 5.6 version of mysql is deployed in it. As a result, the container can be directly connected, but the machine cannot be connected:
Solution:
1. Edit the configuration file:
vi /usr/lib/sysctl.d/00-system.conf
Add a sentence at the end of the file:
net.ipv4.ip_forward=1
Then restart the network, stop the mysql container, delete the mysql container, and make a new MySQL container from the mirror:
systemctl restart network
docker stop (容器id) //使用docker ps查看
docker rm mysql
docker run --name mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root mysql:5.6
Final problem solving
