nginx lua 找不着ffi模塊

出現以上錯誤爲未加載luajit模塊。在編譯安裝的nginx時候必定要注意添加luajit的lib、include/luajit-2.0的環境變量

export LUAJIT_LIB=/usr/local/luajit/lib  

export LUAJIT_INC=/usr/local/luajit/include/luajit-2.0

 

斷定是否爲lua/仍是的luajit：nginx.say(_version) 輸出有版本號爲lua，nginx.say(jit.version)輸出版本號luajit

查看nginx 使用的lua類庫 ldd  /usr/local/nginx/sbin/nginx  |grep lua  是否爲luajit
