nginx使用lua直接調用mongodb

https://github.com/bigplum/lua-resty-mongol 這個是lua的mongodb驅動，須要安裝openresty 1.0.11.7,這裏安裝1.0.11.28

# wget https://openresty.org/download/ngx_openresty-1.0.11.28.tar.gz

# tar xzvf ngx_openresty-1.0.11.28.tar.gz

# cd ngx_openresty-1.0.11.28

# ./configure --prefix=/data/app/openresty --with-luajit && gmake && gmake install

......

# curl https://codeload.github.com/bigplum/lua-resty-mongol/zip/master -o lua-resty-mongol-master.zip

# unzip lua-resty-mongol-master.zip

# make install

# cp -a /usr/local/openresty/lualib/resty/mongol /data/app/openresty/lualib/resty/

tengine配置：

nginx.conf

在http片斷中添加以下行

lua_package_path '/data/app/openresty/lualib/?/init.lua;/data/app/openresty/lualib/?.lua;;';

添加操做mongo的lua腳本

# cat /data/app/tengine/lua/getmongo.lua

local mongo = require "resty.mongol"
local conn = mongo:new()
conn:set_timeout(1000)
local ok, err = conn:connect("127.0.0.1",27017)
ngx.header.content_type="text/explain"
if not ok then
    ngx.say("connect failed: "..err)
end
local db=conn:new_db_handle("test")
local col = db:get_col("test")
local r = col:find_one({name="dog"},{_id=0})
for k,v in pairs(r) do
    ngx.say(k..": "..v)
end

# cat insertmongo.lua

local request_method = ngx.var.request_method  
local args = nil  
if "GET" == request_method then  
    args = ngx.req.get_uri_args()  
elseif "POST" == request_method then  
    ngx.req.read_body()  
    args = ngx.req.get_post_args()
end
ngx.header.content_type="text/explain"
if args == nil then
    ngx.say("error:no args")
end

local mongo = require "resty.mongol"
local conn = mongo:new()
conn:set_timeout(1000)
local ok, err = conn:connect("127.0.0.1",27017)
if not ok then
    ngx.say("connect failed: "..err)
end
local db = conn:new_db_handle("test")
local col = db:get_col("test")
local docs = {args}
local ist, isterr = col:insert(docs,0,0)

if isterr then
    ngx.say("insert error: "..isterr)
else
    ngx.say("insert success.")
end

在tengine的server片斷中添加以下

server

{

listen 80; #listen end

    server_name 127.0.0.1; #server_name end

    client_max_body_size 50m;

    location /mongodb/get {

            content_by_lua_file /data/app/tengine/lua/getmongo.lua;
            
    }

}

往test庫的test表裏插入數據並測試結果

# curl "http://127.0.0.1/mongodb/get"
name: dog
age: 12
