A tcp2http module for nginx.
Most code are copied from ngx-tcp-module ngx-http-module , and the directives/constants/APIs are using it with ngx-lua module.
Still need ngx-tcp-module's ngx.req.socket() to read data;
Thanks for great job of ngx-lua module, ngx-tcp module.

# tell nginx's build system where to find luajit:
export LUAJIT_LIB=/usr/local/lib
export LUAJIT_INC=/usr/local/include/luajit-2.0
# or tell where to find Lua
#export LUA_LIB=/path/to/lua/lib
#export LUA_INC=/path/to/lua/include
# Here we assume Nginx is to be installed under /opt/nginx/.
./configure --prefix=/opt/nginx \
--add-module=/path/to/ngx-tcp2http
make -j2
make install
# on 64bit os, the soft link maybe needed to run nginx:
ln -s /usr/local/lib/libluajit-5.1.so.2.0.0 /lib64/libluajit-5.1.so.2
nginx.conf:
tcp2http {
server {
listen 8000;
location /
{
content_by_lua '
local sock = ngx.req.socket()
local re = sock:receive()
if re == nil then
ngx.print("error")
end
ngx.print(re)
';
}
}
}
test.lua:
local a = 0
a = a + 1
local f = io.open("/tmp/aaaa", "wb")
f:write("xxxx")
f:close()
local sock = ngx.req.socket()
while true do
local re = sock:receive(10)
if re == nil then
break
end
ngx.print(re)
end
Also there is a redis proxy example:
-
cp examples/redis.lua path-to-nginx/conf
-
vi nginx.conf add:
tcp { server { listen 8000; location / { content_by_lua_file conf/redis.lua; } } }
-
run redis on default port
redis-server
-
issue a redis-benchmark test:
redis-benchmark -q -p 8000 -c 200 -n 100000
