由于需要获得本机的IP地址,所以需要 :
local socket = require('socket')
local server_hostname = socket.dns.gethostname()
local server_ip = socket.dns.toip(server_hostname)
需要下载源码编译:luasocket-2.0.2.tar.gz
- 解压好之后首先修改config文件来制定安装的路径,修改涉及的三个地方:
# 由于是先安装的openresty-1.13.6.1:/opt/soft/openresty/
LUAINC=-I/opt/soft/openresty/luajit/include/luajit-2.1/
INSTALL_TOP_SHARE=/opt/soft/openresty/luajit/share/lua/5.1
INSTALL_TOP_LIB=/opt/soft/openresty/luajit/lib/lua/5.1
- 编译安装

然后把 luasocket-2.0.2/src 下所有luaL_reg 替换成 luaL_Reg ,
然后重新编译就可以了。
