ngx_lua module 模块安装

前两天遇到Nginx使用if语句导致Nginx逻辑混乱的问题，Mail给agentzh@gmail.com。他推荐使用ngx_lua module 来处理较为复杂的逻辑，毕竟if is evil。

简述模块安装过程：

-------------------------------------------------------------------------------- ##参考文档 -------------------------------------------------------------------------------- ##项目地址

https://github.com/chaoslawful/lua-nginx-module ##Lua拓展nginx 参考文档 http://rhomobi.com/topics/112 ##Nginx与Lua 参考文档 http://huoding.com/2012/08/31/156 ##HttpLuaModule Nginx Wiki http://wiki.nginx.org/HttpLuaModule

-------------------------------------------------------------------------------- ##下载

-------------------------------------------------------------------------------- wget http://luajit.org/download/LuaJIT-2.0.2.tar.gz wget https://github.com/simpl/ngx_devel_kit/archive/v0.2.19.tar.gz wget https://github.com/chaoslawful/lua-nginx-module/archive/v0.9.1.tar.gz wget http://nginx.org/download/nginx-1.4.3.tar.gz

-------------------------------------------------------------------------------- ##首先安装LuaJIT

------------------------------------------------------------------------------- ##install LuaJIT

tar -zxvf LuaJIT-2.0.2.tar.gz cd LuaJIT-2.0.2 ./configure make make install export LUAJIT_LIB=/usr/local/lib export LUAJIT_INC=/usr/local/include/luajit-2.0

-------------------------------------------------------------------------------- ##安装Nginx

------------------------------------------------------------------------------- ##解压下载下来的ngx_devel_kit以及lua-nginx-module 到/usr/local/src ##install nginx 为方便调试，我添加了echo模块以及开启debug模式

./configure --user=www --group=www \ --prefix=/usr/local/nginx-1.4.3 \ --with-http_stub_status_module \ --with-http_ssl_module \ --with-http_realip_module \ --with-http_perl_module \ --with-pcre=/usr/local/src/pcre-8.12 \ --with-debug \ --add-module=/usr/local/src/lua-nginx-module-0.9.1/ \ --add-module=/usr/local/src/ngx_devel_kit-0.2.19/ \ --add-module=/usr/local/src/echo-nginx-module-0.49/

-------------------------------------------------------------------------------- #启动nginx -------------------------------------------------------------------------------- 错误处理：找不到库文件，处理方式如下。

echo "/usr/local/lib" > /etc/ld.so.conf.d/usr_local_lib.conf ldconfig #重新启动 /usr/local/nginx-1.4.3/sbin/nginx
