安装 LuaJIT
liunx (使用openresty内置的luajit)
在安装好openresty之后，配置好对应环境变量，举例如下：
添加如下内容到 ~/.bashrc
export PATH="$PATH:/usr/local/openresty/luajit/bin"
linux (单独安装)
到 LuaJIT 官网 http://luajit.org/download.html 下载源码
wget http://luajit.org/download/LuaJIT-2.1.0-beta3.tar.gz
tar -xvf LuaJIT-2.1.0-beta3.tar.gz
cd LuaJIT-2.1.0-beta3
make
sudo make install
sudo ln -sf `pwd`/luajit-2.1.0-beta3 /usr/local/bin/luajit
验证 LuaJIT 是否安装成功
luajit -v
得到如下结果
LuaJIT 2.1.0-beta3 -- Copyright (C) 2005-2022 Mike Pall. https://luajit.org/
或者试试 hello world
echo "print('hello world')" >> hello.lua
luajit hello.lua
得到如下结果
hello world
