Three, installation

3.1 Check the installation environment

• Upload the installation package and dependencies to the centos7 server, the test path of this document is: /home/docker/docker-install-package

• After the upload is successful, the file is as follows:

[root@hadoop4 docker]# ll
总用量 35440
-rw-r--r--. 1 root root    25976 9月  29 15:42 container-selinux-2.9-4.el7.noarch.rpm

drwxr-xr-x. 2 root root     4096 9月  29 15:46 package

• Wherein packagestoring the previously downloaded all the required packages, as follows:

3.2 Start the installation

3.2.1 Batch installation of dependent packages:rpm -Uvh *.rpm --nodeps --force

[root@hadoop4 package]# rpm -Uvh *.rpm --nodeps --force

Fourth, check the docker installation

• Start docker:systemctl start docker
• View the dockerlist of startup containers:docker ps

[root@hadoop4 docker]# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

Or check the docker version

docker version 

• Successful installation
• tips: If an error is reported during the installation, and there is a package that cannot be found, download it after the Baidu address, and then install it.

Then install Rancher based on the Docker image

1. Search and download rancher/rancher mirror

 docker pull rancher/rancher：

2. View the pulled mirror list (this step can be omitted)

docker image ls

1. Create two mount directories

mkdir -p /rancher/rancher
mkdir -p /rancher/auditlog

2 Create and run the rancher container

docker run -d --restart=unless-stopped -p 80:80 -p 443:443 \
-v /rancher/rancher:/var/lib/rancher \
-v /rancher/auditlog:/var/log/auditlog \
--name rancher rancher/rancher 

Note:

针对以上参数介绍
-p 80:80 -p 443:443 容器端口映射
-v /rancher/rancher:/var/lib/rancher 容器目录映射
-v /rancher/auditlog:/var/log/auditlog 容器目录映射
–name rancher rancher/rancher 为rancher/rancher 取名为 rancher

Docker container added to boot

docker update --restart=always containers/ID

Access ip: port number

1.> rancher-server:

ip:8080

2.> rancher:

ip:80

If you need to use your own SSL signature certificate, you can specify it according to the following parameters:

通过如下三个参数指定自己的签名证书
-v /etc/<CERT_DIRECTORY>/tls.crt:/etc/rancher/ssl/cert.pem \
-v /etc/<CERT_DIRECTORY>/tls.key:/etc/rancher/ssl/key.pem \
-v /etc/<CERT_DIRECTORY>/cacerts.pem:/etc/rancher/ssl/cacerts.pem \

The command reference is as follows:

 docker run -d --restart=unless-stopped \
  -p 80:80 -p 443:443 \
  -v /rancher/rancher:/var/lib/rancher  \      
  -v /rancher/auditlog:/var/log/auditlog \
  -e AUDIT_LEVEL=3 \
  -v /etc/<CERT_DIRECTORY>/tls.crt:/etc/rancher/ssl/cert.pem \   
  -v /etc/<CERT_DIRECTORY>/tls.key:/etc/rancher/ssl/key.pem \    
  -v /etc/<CERT_DIRECTORY>/cacerts.pem:/etc/rancher/ssl/cacerts.pem \
  --name rancher rancher/rancher 为rancher/rancher

Then you can access Rancher through the browser. If you can access it normally, it means it has been installed.

Set the password first. After setting the

password, you need to set the url address.

Finally, log in and enter, set the language to be displayed in Chinese in the lower right corner
