原文外掛簡介
NS Chat Plugin enables real-time communication between WordPress users using WebSocket technology, powered by the Workerman library.
Key Features:
* Real-time private chat between users
* Visual unread message indicators
* Persistent chat history stored in the database
* Lightweight modular JS + PHP architecture
* Automatic migration and sync of WP users to chat system
* Linux daemon service with SSL support for secure connections
* Future-ready integration with NFS or AWS S3 for file upload/download
Planned Features:
* Message editing and deletion
* Read receipt indicators (message seen)
* File attachments with optional NFS or AWS S3 integration
Ideal for community websites, intranets, or any platform requiring internal messaging without third-party services.

WebSocket Server Setup (Linux with SSL)
Create a systemd service file:
bash
sudo vim /etc/systemd/system/websocket_server.service
Paste the following content:
bash
[Unit]
Description=WebSocket Server for NS Chat (SSL)
After=network.target
[Service]
ExecStart=/usr/bin/php /file/to/path/yourdomain/wp-content/plugins/ns-chat/server.php start
Restart=always
RestartSec=25
User=www-data
Group=www-data
StandardOutput=file:/var/log/websocket_server.out.log
StandardError=file:/var/log/websocket_server.err.log
[Install]
WantedBy=multi-user.target
Add SSL context in server.php:
php
$context = [
'ssl' => [
'local_cert' => '/path/to/file.crt',
'local_pk' => '/path/to/file.key',
'verify_peer' => false,
]
];
Set permissions for plugin folder:
bash
sudo chown -R www-data:www-data /path/to/ns-chat/
sudo chmod -R 775 /path/to/ns-chat/
Reload and start the daemon:
bash
sudo systemctl daemon-reload
sudo systemctl enable websocket_server --now
sudo systemctl restart websocket_server
sudo systemctl status websocket_server
Check logs if needed:
bash
/var/log/websocket_server.out.log
/var/log/websocket_server.err.log
Custom Port Configuration
By default, the WebSocket server listens on port 2346.
To use a different port:
Change the port in server.php:
php
$wsWorker = new Worker('websocket://0.0.0.0:2346', $context);
Change the port in ns-chat.php:
php
$ws_port = 2346;
You can check and change the port in chat-ui.js:
js
const port = nschat_data.wsPort || 2346;
If the port is closed, then open a new port on your server’s firewall:
bash
sudo ufw allow
sudo firewall-cmd --permanent --add-port=
sudo firewall-cmd --reload
sudo iptables -A INPUT -p tcp --dport
sudo iptables-save > /etc/iptables/rules.v4
Database Tables
The plugin creates and uses the following tables:
wp_ns_chat_dialogues
wp_ns_chat_messages
wp_ns_chat_users
Tables are created and populated automatically on plugin activation.
User Synchronization
Initial migration of all users from wp_users to wp_ns_chat_users on plugin activation.
New registrations are handled by:
php
add_action('user_register', 'ns_chat_add_user_on_registration');
Profile updates are synced via:
php
add_action('profile_update', 'ns_chat_update_user_data');
You may bind these functions to custom hooks based on your app’s logic.
