我们通过yum安装的lua默认是5.1版本，如果不符合我们有的程序需要，可以通过源码编译安装最新版lua。过程记录如下:
下载->解压->编译三步曲:
wget http://www.lua.org/ftp/lua-5.3.4.tar.gz tar -xzf lua-5.3.4.tar.gz cd lua-5.3.4 make linux test
系统如果没有安装readline依赖包，编译过程中可能会出现以下错误:
解决办法：yum install libtermcap-devel ncurses-devel libevent-devel readline-devel -y
再次编译安装即可成功.

替换原来的lua
