Corporate Proxy - Permanent Settings for PHP CLI

If you’re using our application within a corporate network that requires proxy settings, you might encounter issues when running PHP CLI commands that attempt to access the Internet.

To resolve this, you need to configure permanent proxy settings for the PHP CLI environment.

Symptoms

When running the command:

php occ app_api:app:register test-deploy docker_socket_proxy --info-xml https://raw.githubusercontent.com/nextcloud/test-deploy/main/appinfo/info.xml --test-deploy-mode --no-ansi --no-warnings

You may receive an error similar to:

file_get_contents(https://raw.githubusercontent.com/nextcloud/test-deploy/main/appinfo/info.xml): Failed to open stream: Connection timed out at /var/www/html/custom_apps/app_api/lib/Service/ExAppService.php#277

Cause

This issue occurs because the PHP CLI environment does not have the proxy settings configured, unlike the web PHP environment which may already be using proxy settings specified in your web server configuration.

Permanent Solution

To permanently configure proxy settings for PHP CLI, you can either modify the PHP CLI php.ini file or set environment variables system-wide.

Method 1: Edit PHP CLI php.ini File

Locate the PHP CLI php.ini File

Run the following command to find the loaded configuration file for PHP CLI:
```
php --ini
```
Look for the line:
```
Loaded Configuration File: /path/to/php.ini
```
Edit the php.ini File

Open the php.ini file in a text editor with the appropriate permissions:
```
sudo nano /path/to/php.ini
```

Add Proxy Settings

Add the following lines to configure the proxy settings:

[HTTP]
; Proxy settings for HTTP
http.proxy_host = "proxy.example.com"
http.proxy_port = 8080
http.proxy_user = "username"
http.proxy_password = "password"

[HTTPS]
; Proxy settings for HTTPS
https.proxy_host = "proxy.example.com"
https.proxy_port = 8080
https.proxy_user = "username"
https.proxy_password = "password"

Replace the placeholders with your actual proxy server details:

proxy.example.com: Your proxy server address.
8080: Your proxy server port.
username: Your proxy username (if required).
password: Your proxy password (if required).

Save and Close the File

Save the changes and exit the text editor.
Verify the Configuration

Run the PHP CLI command again:
```
php occ app_api:app:register
```
It should now be able to access the Internet through the proxy.

Note

Not all PHP functions respect the proxy settings in php.ini. If issues persist, consider using system-wide environment variables.

Method 2: Set System-Wide Environment Variables

Edit Shell Profile

For a permanent solution, add the proxy settings to the system-wide environment variables. Open the /etc/environment file:
```
sudo nano /etc/environment
```

Add Proxy Environment Variables

Add the following lines to the file:

http_proxy="http://proxy.example.com:8080"
https_proxy="http://proxy.example.com:8080"

# If your proxy requires authentication:
http_proxy="http://username:password@proxy.example.com:8080"
https_proxy="http://username:password@proxy.example.com:8080"

Replace the placeholders with your actual proxy details.

Apply the Changes

Log out and log back in, or reboot the system to apply the changes.

Verify the Configuration

Run the command again:

php occ app_api:app:register test-deploy docker_socket_proxy --info-xml https://raw.githubusercontent.com/nextcloud/test-deploy/main/appinfo/info.xml --test-deploy-mode --no-ansi --no-warnings

It should now work without connectivity issues.

Note

This method sets the proxy settings for all users and applications on the system.

Troubleshooting

Incorrect Proxy Details

Ensure all proxy details are correct. Incorrect hostnames, ports, or credentials will prevent connectivity.
Environment Variables Not Loaded

Make sure the environment variables are correctly loaded. A system reboot or re-login may be necessary.
Firewall Restrictions

Verify with your network administrator that your system is allowed to access the Internet through the proxy.
