The Communications Server TCP⁄IP stack provides an AF_UNIX stream socket for each of the interfaces (see Table 2). The interfaces can be used by one or more applications to receive notifications for the data that is being collected. The TCP⁄IP stack acts as the server for these AF_...

socket大家应该很熟悉,以tcp/ip协议族为传输协议,用于跨主机通信,而unixsocket就是在socket的框架上发展出一种IPC机制(进程间通信),UDS(UNIX Domain Socket)提供面向流和面向数据包两种API接口,类似于TCP和UDP,其中SOCK_STREAM是很可靠的,消息既不会丢失也不会顺序错乱,比传统的socket效率更高,一般是tcp传输的两倍...
On Unix, you can connect to the mysqld server by using two different ways: a Unix socket file (for example,/var/run/mysqld/mysqld.sock), or by using TCP/IP (for example,127.0.0.1:3306). A connection that is created with a Unix socket file is faster than TCP/IP but can only be...
UNIX Socket 步骤 创建Socket: 使用`socket()` 函数创建一个套接字,指定协议组、类型和协议。 常见的协议族有 `AF_UNIX`(用于 UNIX 域套接字)和 `AF_INET`(用于网络套接字)。 常见的类型有 `SOCK_STREAM`(用于可靠的面向连接的通信)和 `SOCK_DGRAM`(用于无连接的通信)。
解决方法1 sudo切换至root权限,运行docker命令 应该都是权限的问题,忽略了root用户的切换导致docker起不来 解决方法2 docker守护进程启动的时候,会默认赋予名字为docker的用户组读写Unix socket的权限,因此只要创建docker用户组,并将当前用户加入到docker用户组中,那么当前用户就有权限访问Unix socket了,...
