Installation tutorial

Secondary development can be carried out through the following open source projects.

  1. UCToo-docker project source code https://gitee.com/UCT/uctoo-docker

  2. UCToo Application Template Server Side PHP Project https://gitee.com/uctoo/uctoo

  3. UCToo application template PC-side VUE project https://gitee.com/UCT/uctoo-app-server-vue

cloudbase one-click cloud deployment instructions

  1. It is recommended to use cloudbase one-click deployment. If you are prompted that there is no local environment during installation, please log in to Tencent Cloud->Cloud Development Cloudbase->Environment Overview to activate a cloud development environment (currently only billing is supported).
  2. You must first deploy the UCToo application template server-side PHP project with one click. After the project is deployed, go to Tencent Cloud->Cloud Development Cloudbase->My Application, you can get the backend access address, which is the backend baseAPI address.
  3. Log in to the backend instance through Tencent Cloud->Cloud Development cloudbase->Cloud hosting->uctooserver service->uctooserver-xxx version->Instance->Webshell (if there is no instance under the version, please visit the backend home page first, activate an instance to run ), command line cd to the /var/www/html/uctoo directory, run the php think uctoo:install command to initialize the database (if the installation command fails, it prompts the database to hibernate, please wait a few seconds for the database to activate and then run the command again The .uctoo:install command currently only supports the cloudbase one-click installation environment).
  4. Deploy the PC-side VUE project of the UCToo application template with one click. When the project is initialized and deployed, the user needs to fill in the baseAPI address obtained in step 2 above. Front-end VUE projects can obtain back-end services from baseAPI. After the deployment is complete, you can get the front-end access address in Tencent Cloud -> Cloud Development Cloudbase -> My Application.
  5. You can view the deployed front-end project code through Tencent Cloud -> Cloud Development Cloudbase -> Static Website Hosting.
  6. You can manage the database through Tencent Cloud->Cloud Native Database TDSQL-C->Login. If the database is not started, start it first.
  7. You can manage the mounted CFS file system through Tencent Cloud -> File Storage Management. The file system is mounted in the back-end /var/www/html directory, which is used to save the user’s UCToo APP server code and static resource files.
  8. After the initial installation, the front-end and back-end access addresses automatically assigned by cloudbase are inconsistent with the front-end and back-end domain names configured by users. Basic configuration -> custom domain name configuration (front-end access URL), the domain name set by the user can take effect.
  9. After the installation is complete, you can log in to the management background with the supermanage account set in the initial installation, install more built-in modules through the system management -> module management function, or go to the UCToo application market https://appstore.uctoo.com to purchase more modules for installation to the local instance.

CI/CD advice

  1. One-click cloud deployment copies the code of the git repository to CFS to run persistently and save changes.
  2. You can fork the source code library for secondary development. Modify the git address in the Dockerfile to deploy the secondary development version. Override installation can be done by deleting the /var/www/html/uctoo/public/index.php file in CFS.
  3. You can run the php think uctoo:install -r command in the /var/www/html/uctoo/ directory in the Webshell to reset the database content to the initial installation.
  4. The product has a built-in API management module, which can provide basic features such as development testing and continuous iteration.
