1.CentOS7默認已經安裝了5.1.4
①查看當前lua版本號：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.編譯Lua5.3版本
①下載lua-5.3.3.tar.gz
②make linux
出現錯誤：lua.c:80:31: fatal error: readline/readline.h: No such file or directory
表示需要安裝依賴庫：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被安裝到了/usr/local/bin中
④lua -v查看版本，發現還是舊的版本，那我們就將/usr/bin中的lua和luac刪除，然后將/usr/local/bin中的lua和luac創建一個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
