因为 --without-http_rewrite_module 了，所以set指令不生效

这是redis的unix socket
domain的访问接口，如果自动生成的话，一般是redis启动时生成的，如果你不想用的话，可以在配置文件中取消这个配置。

现在就剩这个了，访问8030端口提示ngx_http_lua_ffi_semaphore_new未定义，，

请问你的luajit用的是哪个版本的，LuaJIT-2.1可以在openresty软件包中获得

是2.1.0啊

没有遇到过你的错误，用openresty软件包中维护的LuaJIT看看呢？
试一下，不行我再想想别的原因

@niuhp 访问8030端口提示ngx_http_lua_ffi_semaphore_new未定义
这个解决了吗?我也遇到了。CentOS7下

BG2BKK · 2016-06-19T14:06:19Z

你好，这个是ngx_lua比较新的版本中带有的 resty.semaphore模块，请确定ngx_lua版本包含该模块

我用的openresty 最新版本, luajit2.1.0beta2, 也是同样的问题

BG2BKK · 2016-07-28T06:19:16Z

请问是哪个问题？

反复测试了好几遍,始终如此

BG2BKK · 2016-07-29T12:21:36Z

你好，这个问题是api的更新，曾经也出现过这样的问题中已经解决了，

但是出现这个问题的原因是我版本中的lua-resty-lib没有更新到最新版，仍然使用了ngx_http_lua_ffi_semaphore_new，而新版已经是ngx_http_lua_ffi_sema_new了，这点我很抱歉。之所以一直没有发现，原因是我开发时采用的是tengine+luajit+lua-resty-lib，我当时的ngx_lua版本和lua-resty-lib契合，所以没有报错；当我采用新版openresty时没有进行深入测试，非常抱歉，我正在修复和测试

但是你的问题在于，使用了非openresty维护的luajit版本，openresty维护的LuaJIT是2.1版本以上了，会有与ngx有关的更新，而你是从官方下载的LuaJIT，编译是不会通过的

经过测试，我换用 lua-resty-core的v0.1.6 tag可以正常使用，目前该项目的master分支是v0.1.7rc+了，我不知道如何指定tag作为git项目的sub module，所以我将所需lua-resty-core手动放到我的项目里，然后在README中指明。

非常感谢你的反馈，欢迎使用

BG2BKK · 2016-07-29T13:05:03Z

经过对openresty各版本的比对，我发现api ngx_http_lua_ffi_sema_new的引入是从当前最新版本openresty-1.9.15.1开始的，所以没有发现，看来我的锅轻一点了 :)

解决这个问题的终极办法是，如果想用semaphore的话，每次使用lua-resty-core的时候，需要将lua-resty-core/lib/ngx 和 lua-resty-core/lib/resty 的版本与openresty保持一直，简单粗暴的方法就是，从/usr/local/oprensty/lualib中将ngx和resty目录 copy 到ABTestingGateway的lib/lua-resty-core目录下替换；

我之所以没有将lua_package_path中的路径直接指定到openresty的路径下，原因是1、我们使用的tengine，所以lua-resty-core等lib需要从目录外指定；2、运维人员应该拥有自己指定lib路径的权力。

这样的话，我仍然将本repo中的lib-resty-core保持原状，然后在readme中说明吧。
