Re: [openresty] openresty安装的时候 'ngx.semaphore' 默认没有安装吗？如果没有的话要通过途径安装的呢。。

确定一下你引用的 ngx_lua_module 版本。

This API was first introduced in the 0.9.20 release.

确定一下你引用的 ngx_lua_module 版本。抱歉刚刚粘贴错版本了。

ngx.semaphore

syntax: local semaphore = require "ngx.semaphore"

This is a Lua module that implements a classic-style semaphore API for efficient synchronizations among different "light threads". Sharing the same semaphore among different "light threads" created in different (request) contexts are also supported as long as the "light threads" reside in the same NGINX worker process and the lua_code_cache directive is turned on (which is the default).

This Lua module does not ship with this ngx_lua module itself rather it is shipped with the lua-resty-core library.

Please refer to the documentation for this ngx.semaphore Lua module in lua-resty-core for more details.

This feature requires at least ngx_lua v0.10.0.
