Docker+LNMP+Jenkins+Code Cloud realizes automatic deployment of PHP code

Automated deployment (continuous integration/CI continuous delivery/CD) is a trend in software development and is a good help for the development of DevOps. Today’s practice is based on the Docker Jenkins LNMP code cloud to realize the automated deployment process of PHP code.

Environment configuration

Operating system: CentOS Linux release 7.6.1810

Docker version: 19.03.5

Jenkins version: 2.204.1

Nginx version: 1.15.5

PHP version: 7.2.26

MySQL version: 8.0.18

Redis version ：5.0.5

Code Cloud: Code Warehouse

Code Cloud Warehouse Preparation

Create Project Warehouse

Jenkins preparation

Install the ssh plug-in

Because building the project requires executing some shell commands on the server, So use ssh login method to communicate with the remote server.

1. System Management->Plug-in Management

2. Search: ssh, install it

##New project task

1. Source code management selection: git

2. Repository URL: warehouse address (mine is the code cloud warehouse)

3. Credentials, select Add

4. Add credentials

5. Configure the warehouse private key (for details, please view the warehouse key management help of Code Cloud)

After the credentials are configured successfully, just select the Username configured in the previous step. If you successfully connect to the warehouse address, no error will be reported.

Build trigger selection: Github hook trigger for GITScm polling

Build environment: Use secret text(s) or file(s) //Transfer files privately

Credentials: Select the specified credentials git

1. System Management->System Configuration

2. Configure remote server ssh related information

Build: Execute shell script on remote host using ssh //Execute remote server shell script when building

1. Fill in SSH site //Remote server ssh Login

2. Command //shell script

Remarks:

Because the code is automatically deployed in the workspace directory of jenkins, and the project’s site directory is in /data/ www, so when building, you need to copy the updated code file to the project site (there are many ways to implement it. Here, use a copy of the code because the size of the code will not take up a lot of space. Nowadays, many static Resources are placed on some cloud services)

I initially used the soft connection method, but because nginx does not support soft connection access.

After the configuration is completed, click Save

Modify the code in the code cloud warehouse, and then submit the PR to the master branch

Manual construction of deployment tasks

Click Build manually to realize automated code deployment

Remarks:

Also It can be configured to automatically build directly after monitoring git push (this is recommended for the test environment)

Clicking the build manually is for better management (this is recommended for the production environment)

If the task construction fails, there will be an error message and a red mark //very convenient for management
