LuaJIT是Lua的JIT编译版本，较为著名的扩展包有SciLua，与Julia性能接近；OpenResty可以显著改善服务器的并发性能。在linux环境下，下载LuaJIT-2.0.5.tar.gz，输入以下命令安装，
tar -zxvf LuaJIT-2.0.5.tar.gz cd LuaJIT-2.0.5 make -j 16 make install PREFIX=/backup/home/misaraty/soft/luajit
接着，在.bashrc中添加环境变量，
#luajit export PATH=$PATH:/backup/home/misaraty/soft/luajit/bin export LUAJIT_LIB=/backup/home/misaraty/soft/luajit/lib export LUAJIT_INC=/backup/home/misaraty/soft/luajit/include/luajit-2.0
Lua的使用可以参考Lua教程-菜鸟教程、Lua教程-极客学院等。
