下载openrestry安装包, 解压后执行如下命令安装
sudo apt-get install libreadline-dev libncurses5-dev libpcre3-dev libssl-dev perl make
$ ./configure --with-luajit如果报下面的错误
platform: linux (linux)
you need to have ldconfig in your PATH env when enabling luajit.
是因为找不到命令ldconfig, 这个命令一般是在/sbin/目录下的，所以先执行
export PATH=$PATH:/sbin然后再执行
make
sudo make install
