Preface

This article mainly introduces how to solve the problem that Rancher cannot add hosts. Let's take a look at the detailed introduction.

The methods are as follows:

Docker version:

two。 Start Docker:

Systemctl daemon-reloadsystemctl enable dockersystemctl start docker

3. Install rancher:

Docker run-d-p 8080 mnt/data/rancher/db:/var/lib/mysql 8080-- restart=always-v / mnt/data/rancher/db:/var/lib/mysql-- name rancher-server-146 rancher/server:v1.6.17

4. Add a host:

Find the id of agent by executing docker ps on the command line, and then execute docker logs id

The agent container was found to be unsuccessful.

First, you need to delete the file under / var/lib/rancher/state, which is used to mark the uniqueness of the host, and then delete the agent container

Next, you need to add dns to / etc/docker/daemon.json

{"registry-mirrors": ["https://2lqq34jg.mirror.aliyuncs.com","https://pee6w651.mirror.aliyuncs.com","https://registry.docker-cn.com","http://hub-mirror.c.163.com"],"dns": [" 8.8.8.8 "," 8.8.4.4 "]}

Finally restart docker

Systemctl daemon-reloadsystemctl restart docker.serviceservice docker restart

After re-adding hosts, check the operation of agent through docker logs id.

As shown in the picture, it works normally. The host is added successfully, and then the services are added.
