提示 module 'ngx_metric.counter' not found: 没找到

但是我是有这个文件的

modules/
├── avg.lua
├── chunk_histogram.lua
├── counter.lua
├── histogram.lua
├── ngx_metric
│   ├── avg.lua
│   ├── chunk_histogram.lua
│   ├── counter.lua
│   ├── histogram.lua
│   ├── ngx_metric.lua
│   └── util.lua
├── ngx_metric.lua
├── ngx_metric_output.lua
└── util.lua   

cat /usr/local/nginx/modules/ngx_metric.lua 的部分代码

 

local util = require "ngx_metric.util"
local counter = require "ngx_metric.counter"
local chunkhisto = require "ngx_metric.chunk_histogram"

local _M = { _VERSION = '0.0.1' }
local mt = { __index = _M }

local function cut_uri(uri, section_len)
    local uri_a = util.str_split(uri, "/")
    local res = ""
    for i = 1, math.min(section_len, #uri_a) do
        res = res .. "/" .. uri_a[i]
    end
    return res
end

这里是哪里出错了？帮忙看下

Answer 2

这个一般是ngx的启动路径问题，ngx_metric.conf配置的是相对路径，所有你的环境需要在/usr/local/nginx下面启动
