安装完依赖软件，按照示例步骤执行，执行到第9步中的第二步报404

[BG2BKK]

额，错误信息呢

[chimisu]

@BG2BKK 已经搞定了，少装了lua-cjson。

@BG2BKK 执行到这一步：curl 127.0.0.1:8030 -H 'X-Uid:39' -H 'X-Real-IP:192.168.1.1'，报500错误，会是什么问题呢？

@BG2BKK 升级了LuaJIT到2.1之后报：2017/03/02 17:41:53 [error] 13574#0: *5 lua entry thread aborted: runtime error: ../lib/lua-resty-core/lib/ngx/semaphore.lua:64: /lib64/libluajit-5.1.so.2: undefined symbol: ngx_http_lua_ffi_semaphore_new

已解决，这个issue可以关闭了

怎么解决的?

#79
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；
