_harbor's Official Installation Guide This paper introduces three installation modes of harbor, which are online installation, offline installation and OVA installation. Due to the limitation of network environment, this paper mainly adopts offline installation.
_The official documents above indicate that you need to rely on Python 2.7 or more, Docker engine 1.10 or more, and Docker Compose 1.6.0 or more.
_CentOS 7.2 comes with Python 2.7.5

Docker has also been installed in advance:

_So there's still a need to install Docker Compose

Download Docker Compose

Download version 1.21.2 of Docker Compose. Reference document

sudo curl -L https://github.com/docker/compose/releases/download/1.21.2/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

Modify docker-compose as an executable file:

chmod +x docker-compose

_Testing for Successful Installation

_Run the command [docker-compose version] to test whether the installation was successful:

Download offline installation packages

In the presence of GitHub Find the download address and download it. I downloaded version 1.5.1 here. The whole file is more than 800MB:

_decompression installation package

tar xvf harbor-offline-installer-v1.5.1.tgz

_Modify configuration file [harbor.cfg]

vi harbor.cfg

The necessary parameters are:

1. hostname: The host name of the target host for accessing the UI and registering services. You can't use localhost and 127.0.0.1 because harbor needs to be accessed by an external client. I changed the IP address here.

2. ui_url_protocol: A protocol for accessing UI and token/notification services, default to http. If SSL authentication is enabled on Nginx, it can be set to https. The default http I use here is http.

3. max_job_workers: The maximum number of replicated workers in the job service, which is written by default here, is 50. Considering the performance of my server, I changed it to 5 here.

4. customize_crt: Set to on, the prepare script creates the private key and root certificate for generating/verifying registry tokens. If set to off, the key and root certificate will be provided by an external source. I set on.
   
   

   customize_crt.png
5. ssl_cert: The location of the SSL certificate, which takes effect only when the protocol is set to https.
6. ssl_cert_key: The location of the SSL key, which takes effect only when the protocol is set to https.
7. Seckey_path: The path where the password is stored. It's better not to change it here. Otherwise, there will be an error later. I changed it to [/data/admin/].
   
   

   secretkey_path.png
8. log_rotate_count: The number of log files that are retained and the previous logs are deleted iteratively when the maximum value is reached.
9. log_rotate_size: In order to save space, I set up a maximum of five logs, each up to 200 MB.

10. db_password: The root password of MySQL database for DB authentication.

_Run [prepare] Update parameters

./prepare

_Start Installation

_Execute [install.sh] for installation

[root@localhost harbor]# ./install.sh

 ----Harbor has been installed and started successfully.----

Now you should be able to visit the admin portal at http://192.168.242.132 . 
For more details, please visit https://github.com/vmware/harbor .

Installation completed, visit http://192.168.242.132 to try, 502 error, why?

_looks at the container through the command [docker ps], and finds that there are eight containers, of which the harbor-adminserver node has been in the Restarting state.

View adminserver's log

tail -n 50 /var/log/harbor/adminserver.log

See the following error: failed to initialize the system: read/etc/adminserver/key: is a directory

_This is because the setting of secretkey in [usr/local/harbor/docker-compose.yml] is different from that of [harbor.cfg], [docker-compose.yml]:
_Change the secretkey_path in [harbor.cfg] back to [data], then execute the docker-compose down, stop and delete all containers.

_Then delete the directory [data/secretkey]

rm -rf /data/secretkey

Rerun [prepare]

./prepare

Finally, create the container and start it up

docker-compose up –d

_Re-run [docker ps] to see the state of the container

It's all right. Visit [http://192.168.242.132] and see if you can make a normal visit:

_Log in with admin account

_Successful construction.
