Android create Unix domain socket by bound file descriptor

Android provide LocalServerSocket and LocalSocket to create Unix domain sockets for local interprocess communication (IPC). Unix socket address can behave in three types[1],

• pathname
• unnamed
• abstract

LocalServerSocket provide two public constructors for create socket in Linux abstract namespace[2] and create socket using file descriptor that's already been created and bound[3].

Create LocalServerSocket using [FileDescriptor](https://docs.oracle.com/javase/7/docs/api/j

# 生成 dhparam.pem 文件, 在命令行执行任一方法:

# 方法1: 很慢
openssl dhparam -out /etc/nginx/ssl/dhparam.pem 2048

# 方法2: 较快
# 与方法1无明显区别. 2048位也足够用, 4096更强
openssl dhparam -dsaparam -out /etc/nginx/ssl/dhparam.pem 4096
