一、效果演示
二、PHP7安装Swoole扩展
PHP swoole 扩展下载地址
Github:https://github.com/swoole/swoole-src/tags
php官方扩展库:http://pecl.php.net/package/swoole
开源中国:http://git.oschina.net/swoole/swoole/tags
1.自定义安装
# 下载
wget https://pecl.php.net/get/swoole-4.3.3.tgz
# 解压
tar zxf swoole-4.3.3.tgz
# 编译安装扩展
# 进入目录
cd swoole-4.3.3
# 执行phpize命令,产生出configure可执行文件
# 如果不知道phpize路径在哪里 可以使用which phpize查看相应路径
/usr/bin/phpize
# 进行配置 如果不知道php-config路径在哪里 可以使用which php-config 查看相应路径
./configure --with-php-config=/usr/bin/php-config
# 编译和安装
make && make install
vi /etc/php.ini
复制如下代码
extension=swoole.so
放到你所打开或新建的文件中即可,无需重启任何服务
# 查看扩展是否安装成功
php -m|grep swoole
2.宝塔面板安装PHP swoole扩展
如果感觉上述安装较为复杂,可以使用宝塔面板实现一键安装
三、配置nginx反向代理
-
使用xshell连接远程阿里云服务器 -
使用命令(find / -name nginx.conf)查找nginx.conf所在的配置文件 -
使用命令(vim /etc/nginx/nginx.conf)查找进入到vim编辑器 查看到可以引入/etc/nginx/conf.d/ 下的配置文件信息 -
使用命令(cd /etc/nginx/conf.d/)进入到该路径下,并新建配置文件:study.lishuo.net.conf -
配置nginx反向代理,实现访问study.lishuo.net 域名转发端口号到127.0.0.1:9511 也就是转发到webscoket运行的端口号
upstream study{
server 127.0.0.1:9511;
}
server {
listen 80;
server_name study.lishuo.net;
error_page 404 /404.html;
location = /404.html {
}
location / {
index index.php index.html index.htm;
if (!-e $request_filename) {
rewrite ^(.*)$ /index.php?s=/$1 last;
}
client_max_body_size 100m;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_read_timeout 604800s;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_pass http://study;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
location ~ .php$ {
fastcgi_pass 127.0.0.1:9001;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}

2.服务端代码(PHP代码)
wechat_websocket.php
<?php
$ws = new Swoole\WebSocket\Server('0.0.0.0', 9511);
$ws->on('Open', function ($ws, $request) {
echo $request->fd . '我连接上了';
});
$ws->on('Message', function ($ws, $frame) {
$params = json_decode($frame->data, true);
if (isset($params['type']) && isset($params['type'])=='active'){
echo '这是心跳监听消息';
}else{
if (isset($params['uid']) && !empty($params['uid'] == 666)) {
$fd = 2;
} else {
$fd = 1;
}
$ws->push($fd, json_encode($params, JSON_UNESCAPED_UNICODE));
}
});
$ws->on('Close', function ($ws, $fd) {
echo "client-{$fd} is closed\n";
});
$ws->start();
六、代码已经编写完了
- 把服务端代码上传到Linux操作系统里
- 然后切到该目录下进行运行
php wechat_websocket.php
七、END
如果最后还是没有成功实现功能的话,我把所有源代码都上传到了如下仓库地址:客服聊天
