安装nginx环境，含lua时遇到报错ngx_http_lua_common.h:20:20: error: luajit.h: No such file or directory的解决

下面是安装nginx+lua环境时使用的相关模块及版本，ngx_devel_kit和lua-nginx-module模块用的都是github上最新的模块.并进行了LuaJIT的安装。

#Install nginx by 2019-12-12

make && make install
cd ..
cd nginx-1.14.2

　 .configure执行是成功的，但是在进行make的时候遇到报错：ngx_http_lua_common.h:20:20: error: luajit.h: No such file or directory，详细报错内容如下：

In file included from ../lua-nginx-module-0.10.15/src/ngx_http_lua_script.h:11:0,
                 from ../lua-nginx-module-0.10.15/src/ngx_http_lua_script.c:13:
../lua-nginx-module-0.10.14/src/ngx_http_lua_common.h:20:20: fatal error: luajit.h: No such file or directory
#include <luajit.h>
                    ^
compilation terminated.
make[1]: *** [objs/addon/src/ngx_http_lua_script.o] Error 1
make[1]: Leaving directory `/usr/local/src/nginx-1.14.2'
make: *** [build] Error 2

解决方法：把lib的路径写入/etc/profile中

# vim /etc/profile
export LUAJIT_LIB=/usr/local/lib
export LUAJIT_INC=/user/local/include/luajit-2.1
# source /etc/profile

　重新编译即可成功！
