LuaJIT：lua的一个即时编译器

Nginx Devel Kit：NDK是一个nginx模块，以一种可浸染于其他nginx模块的办法，扩展nginx核心功能。

Lua Nginx Module：该模块将Lua阐明器或LuaJIT嵌入到nginx核心中，并通过nginx子要求将强大的Lua线程（也称为Lua协程）集成到nginx事宜模型中。

nginx：web做事

wget -c http://luajit.org/download/LuaJIT-2.0.5.tar.gz

tar zxvf LuaJIT-2.0.5.tar.gz

cd LuaJIT-2.0.5

make install PREFIX=/opt/luajit

export LUAJIT_LIB=/opt/luajit/lib

export LUAJIT_INC=/opt/luajit/include/luajit-2.0

( 如果不设置环境变量，在nginx编译的时候会找不到lua模块：./configure: error: ngx_http_lua_module requires the Lua library.)

nginx报错: error while loading shared libraries: libluajit-5.1.so.2: cannot open shared object file: No such file or directory

可以实行：

ln -s /usr/local/luajit/lib/libluajit-5.1.so.2 /lib64/libluajit-5.1.so.2

或者添加环境变量：

echo 'export LD_LIBRARY_PATH=/opt/luajit/lib:$LD_LIBRARY_PATH' >> /etc/profile

source /etc/profie

vim /opt/nginx/conf/nginx.conf

#在nginx.conf中，server->location配置

location /hello {

default_type 'text/plain';

content_by_lua 'ngx.say(\"大众hello, lua\"大众)';

}

/opt/nginx/sbin/nginx

http://[做事器IP]/hello

可以看到

hello, lua
