1.CentOS7默认已经安装了5.1.4 ①查看当前lua版本号： ``` lua -v Lua 5.1.4  Copyright (C) 1994-2008 Lua.org, PUC-Rio ``` ②查看lua和luac的位置： ``` which lua luac /usr/bin/lua /usr/bin/luac ``` 2.编译Lua5.3版本 ①下载lua-5.3.3.tar.gz ``` wget http://www.lua.org/ftp/lua-5.3.0.tar.gz tar zxf lua-5.3.0.tar.gz cd lua-5.3.0 ``` ②make linux 出现错误：lua.c:80:31: fatal error: readline/readline.h: No such file or directory 表示需要安装依赖库：yum install readline-devel ③make install cd src && mkdir -p /usr/local/bin /usr/local/include /usr/local/lib /usr/local/man/man1 /usr/local/share/lua/5.3 /usr/local/lib/lua/5.3 cd src && install -p -m 0755 lua luac /usr/local/bin cd src && install -p -m 0644 lua.h luaconf.h lualib.h lauxlib.h lua.hpp /usr/local/include cd src && install -p -m 0644 liblua.a /usr/local/lib cd doc && install -p -m 0644 lua.1 luac.1 /usr/local/man/man1 可以看到，lua和luac被安装到了/usr/local/bin中 ④lua -v查看版本，发现还是旧的版本，那我们就将/usr/bin中的lua和luac删除，然后将/usr/local/bin中的lua和luac创建一个ln到/usr/bin中即可 cd /usr/bin rm -rf lua luac ln -s /usr/local/bin/lua /usr/bin/lua ln -s /usr/local/bin/luac /usr/bin/luac lua -v Lua 5.3.3  Copyright (C) 1994-2016 Lua.org, PUC-Rio
