Ubuntu 18.04上安装 phpMyAdmin的详细教程
Ubuntu 18.04上的WebSocket服务端程序可以使用libwebsockets库来实现。以下是安装和配置WebSocket服务端程序的步骤:
1. 安装libwebsockets库。可以使用以下命令安装:
```
git clone https://libwebsockets.org/repo/libwebsockets
cd libwebsockets
mkdir build
cd build
cmake ..
make && sudo make install
```
2. 创建WebSocket服务端程序。可以使用以下代码创建WebSocket服务端程序:
```c
#include <libwebsockets.h>
static int callback_http(struct lws *wsi, enum lws_callback_reasons reason, void *user, void *in, size_t len)
{
// 处理HTTP请求
}
static int callback_websocket(struct lws *wsi, enum lws_callback_reasons reason, void *user, void *in, size_t len)
{
// 处理WebSocket请求
}
static struct lws_protocols protocols[] = {
{
"http-only",
callback_http,
0,
0,
},
{
"websocket",
callback_websocket,
0,
0,
},
{ NULL, NULL, 0, 0 }
};
int main()
{
struct lws_context_creation_info info;
struct lws_context *context;
memset(&info, 0, sizeof(info));
info.port = 8000;
info.protocols = protocols;
context = lws_create_context(&info);
while (1) {
lws_service(context, 50);
}
lws_context_destroy(context);
return 0;
}
```
3. 编译并运行WebSocket服务端程序。可以使用以下命令编译并运行WebSocket服务端程序:
```
gcc -o server server.c -lwebsockets
./server
```
