luasocket安裝過程中遇到不少坑，之前采用的是從公司以前服務器的里面找一個其他同學下好的rpm安裝包直接安裝，安裝的路徑以及產生的庫文件在什么位置都不知道怎么控制，今天抽時間一通google，終于跑通了源碼安裝的過程。

官方下載地址：http://files.luaforge.net/releases/luasocket/luasocket/luasocket-2.0.2

?tar -zxvf ?luasocket-2.0.2.tar.gz

cd?luasocket-2.0.2

修改配置文件config

由于是在安裝openresty后再安裝luasocket，修改配置文件為，這樣將制定luasocket生成的庫文件放到openresty默認會尋找的路徑下

INSTALL_TOP_SHARE=/opt/openresty/luajit/share/lua/5.1

INSTALL_TOP_LIB=/opt/openresty/luajit/lib/lua/5.1

?

參考http://blog.csdn.net/wzzfeitian/article/details/8866390教程介紹

make

這種情況下會報錯

這個問題之前查了幾次沒有結果，看錯誤輸出也一直以為是下的源碼包有問題，下了好幾個版本都不行，后來偶然看到了http://stackoverflow.com/questions/20490854/luasocket-c2017-error-lua-h-no-such-file-or-directory

有人遇到了同樣的問題，生硬照搬答案里make LUAINC=-I/usr/include/lua5.1/的方法也沒有解決，反而是看到問題的comment小字有人回復了一句話搞明白了問題的真正原因：

lua.h is the main header file for the Lua C source code. Either you don't have the lua source installed, or you haven't told the compiler where to find it. – Roddy Dec 10 '13 at 9:46?

所以說其實是gcc編譯命令找不到本機lua的源碼到底在什么地方，自然無法編譯。正好錯誤里提示lua.h這個文件找不到，find一下其實就在openresty的build/lua-5.1.5/src下。

修改config文件

LUAINC=-I/opt/ngx_openresty-1.9.3.1/build/lua-5.1.5/src

重新運行make&&make install 成功

?

再去檢查下

INSTALL_TOP_SHARE=/opt/openresty/luajit/share/lua/5.1

INSTALL_TOP_LIB=/opt/openresty/luajit/lib/lua/5.1

這兩個路徑下socket庫文件都已經存在了。

?

其實之前看http://www.linuxidc.com/Linux/2013-12/93516.htm的過程也提到了要修改LUAINC屬性，只不過當時完全不知道這個是干嘛的就滑過去了,其實還是lua生的不行造成的~~~~~
