A tcp module with lua support for nginx.
Most code are copied from ngx-lua-module, and the directives/constants/APIs are planed to be compatible with ngx-lua module.
Thanks for great job of ngx-lua module.
Tested with nginx-1.4.4.

# 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-tcp-lua-module
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:
tcp {
server {
listen 8000;
process_by_lua_file conf/test.lua;
}
}
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; process_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
