1. Install swoole service
1. Download the swoole source code, download address: https://github.com/swoole/swoole-src/releases
2. Upload the tar package to /usr/local/src/swoole, where the installation source files are stored.
3. Decompress the source file, tar –xvfswoole.tar
4. Enter the directory you just decompressed and enter the command phpize
5. Note: phpize is php-devel It can dynamically add extensions to PHP, so please make sure the php-devel package is installed on your machine.
6. Then, enter the following commands in sequence: ./configure, execute the compilation and detection make, and compile swoole
7. The pcre and pcre-devel related software packages are missing, just install them.
8.sudo make install
9.php.ini is generally compiled and installed under etc. After successful installation, we also need to modify php.ini and add the swoole.so extension to it:
10.extension=swoole.so
11. Enter php -m and you can see swoole, indicating that the extension is installed successfully.
2. Install apache and start the swoole service
(1) Test whether the installation is correct and start the swoole Php service
(2) Add the server.php file in apache, and client .php files. The general directory is under var/www/html
(3) Open two terminals. Open these two files under the directory where these two files are located to achieve socket long connection service.
Install lsof: yum -y install lsof
3. Configure the server side

}4. Configure the html front-end
$(document).ready(function(){
varwsurl = "ws://182.92.101.206:9999/";
console.log(wsurl);
varwebsocket = new WebSocket(wsurl);
websocket.onopen= function(evt){
console.log('Server: 打开WebSocket连接');
};
websocket.onclose= function(evt){
console.log('Server: 关闭WebSocket连接');
};
websocket.onmessage= function(evt){
varres = JSON.parse(evt.data);
console.log('Server: 收到消息(来自：'+res+'请求)');
console.log(res);
};
websocket.οnerrοr= function(evt){
console.log('Server: 出现错误');
console.log(evt.data);
}
functiondoSend(msg){
console.log('Client:发送消息 ' + msg);
websocket.send(msg);
}
});5. Start start.php file, cd to the specified directory, and then PHP-CLI runs php start.php. In this method, thread protection is not enabled and the thread is still occupied after the program ends.
require'src/WebSocketSwoole/WebSocketService.php'; // require './WebSocketService.php'; session_start(); // $demoService = new\WebSocketSwoole\WebSocketService(); $demoService =\WebSocketSwoole\WebSocketService::getInstance(); $demoService->run();
