Tencent Cloud Serverless Framework provides a new deployment method for WordPress based on the serverless architecture. By using the Serverless Framework WordPress component, you can quickly deploy a WordPress project in just a few steps.
Architecture Overview
This component mainly creates the following resources for you:
Module
Description
SCF
It implements the access layer of Serverless WordPress to run WordPress
API Gateway
It is the ingress of WordPress and implements RESTful APIs
CFS
It is the serverless storage warehouse for WordPress
TDSQL-C Serverless
You can create a TDSQL-C for MySQL serverless database to implement a pay-as-you-go and automatically scalable database service
VPC
It is used to connect SCF, CFS, and TDSQL-C Serverless over the private network to ensure network isolation
Features
Support for native WordPress framework
With the Serverless WordPress component, you can directly deploy native WordPress projects without having to make any modifications, which is non-intrusive to the framework and supports subsequent version upgrade.
Reduced costs
From the access layer to compute layer to storage layer, everything uses serverless resources to truly implement pay-as-you-go billing and auto scaling, greatly reducing the costs.
Easy deployment
With the Serverless WordPress component, you can quickly complete WordPress application deployment by using just a few lines of configuration in a YAML file, greatly lowering the deployment threshold.
Deployment Steps
You can deploy Serverless WordPress on the command line or in the console in the following steps:
(Optional) You have prepared a custom domain name.
Deployment in console
Note:
Currently, only four regions are supported: Beijing, Guangzhou, Nanjing, and Shanghai.
1. Log in to the SAC console and click Create Application.
2. Enter the application name as prompted, select Application Template > WordPress Application, and click Create to create an application.
3. On the serverless application page, click Access Application to access your WordPress project. You can also configure a custom domain name on the application details page.
Deployment on command line
Note:
Currently, only four AZs are supported: ap-guangzhou-4, ap-shanghai-2, ap-beijing-3, and ap-nanjing-1.
1. Create the wordpress-demo folder locally and download the application from the WordPress official website into it.
2. In the folder, create the serverless.yml configuration file and complete application configuration as follows (for more information on the configuration, please see the configuration document):
app: wordpress
stage: dev
component: wordpress
name: wordpressDemo
inputs:
region: ap-shanghai # Project region
zone: ap-shanghai-2
src:# Project path, which should be your WordPress path
src: ./wordpress
exclude:
- .env
apigw:# API Gateway configuration
customDomains:# (Optional) Bind a custom domain name
-domain: abc.com # The custom domain name to be bound
certId: abcdefg # Unique certificate ID of the custom domain name to be bound
customMap:true# Whether the path is custom
pathMap:
-path: /
environment: release
protocols:# Type of the protocol of the custom domain name to be bound, which is the same as that of the frontend service protocol
- http
- https
After you complete the above configuration, your project structure will be as follows:
.wordpress-demo
├── wordpress # WordPress source file
├── serverless.yml # Configuration file
└── .env # Environment variable file
3. In the root directory, run sls deploy to complete the deployment. Below is an example:
4. After the deployment succeeds, click the URL output in the apigw part, configure the account and password as prompted, and you can start using your WordPress application.
FAQs
What should I do if deployment failed due to permission problems?
Check whether the root account/sub-account has the following permissions:
Check roles: SCF_QcsRole, SLS_QcsRole, and CODING_QcsRole.
Check permissions:
SCF_QcsRole must have the CFSFullAccess permission.
CODING_QCSRole must have the QcloudSLSFullAccess, QcloudSSLFullAccess, and QcloudAccessForCODINGRole permissions.
For a sub-account, you also need to check the following permissions:
The account should have permissions to use SLS, SCF, CFS, TDSQL-C, and CODING.
After a custom domain name was bound, the error message {"message":"There is no api match env_mapping '\\/'"} was reported. What should I do?
How do I modify php.ini to change the limit on the size of uploaded files?
1. Modify the layer code. Move the php.ini file in the etc folder to the etc/php.d folder. You can also directly use the package provided by Tencent Cloud.
When packaging and uploading the layer again, pay attention to the hierarchy in the package and compress only files in the parent directory; otherwise, function initialization will fail:
2. Modify the bootstrap code of the wp-server-xxx function as follows:
How do I troubleshoot the "event too large" error?
Currently, you can only upload an event of up to 6 MB in size for a function. Larger files cannot be uploaded.
Currently, Base64 encoding by API Gateway will increase your code size by 1.5 times. Therefore, we recommend you upload a file below 3.5 MB in size.
How do I modify files in the WordPress root directory?
Currently, such files are mounted to CFS and cannot be modified directly. We recommend you install the File Manager plugin to manage files in the root directory.
