nginx 增加lua 扩展（还是直接用openresty吧）

1、加扩展

#lua
wget http://luajit.org/download/LuaJIT-2.0.5.tar.gz 
tar -zxvf LuaJIT-2.0.5.tar.gz 
cd LuaJIT-2.0.5   
make && make install PREFIX=/usr/local/LuaJIT


cat >> /etc/profile < EOF
export LUAJIT_LIB=/usr/local/LuaJIT/lib
export LUAJIT_INC=/usr/local/LuaJIT/include/luajit-2.0
source /etc/profile
EOF
 
lua -v


#扩展
wget https://github.com/simpl/ngx_devel_kit/archive/v0.3.0.tar.gz
wget https://github.com/openresty/lua-nginx-module/archive/v0.10.9rc7.tar.gz
 
# 解压
tar -zxf v0.3.0.tar.gz
tar -zxf v0.10.9rc7.tar.gz

./configure --prefix=/opt/nginx --pid-path=/opt/nginx/nginx.pid --user=www --group=www --with-poll_module --with-threads --with-file-aio --with-http_ssl_module --with-http_v2_module --with-http_realip_module --with-http_addition_module --with-http_xslt_module=dynamic --with-http_image_filter_module=dynamic --with-http_geoip_module=dynamic --with-http_sub_module --with-http_dav_module --with-http_flv_module --with-http_mp4_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_auth_request_module --with-http_random_index_module --with-http_secure_link_module --with-http_degradation_module --with-http_slice_module --with-http_stub_status_module --with-http_perl_module --with-stream=dynamic --with-stream_ssl_module --with-stream_realip_module --with-stream_geoip_module --with-stream_geoip_module=dynamic --with-stream_ssl_preread_module --with-google_perftools_module --with-compat --with-pcre --with-debug --add-module=/opt/soft/lua-nginx-module-0.10.9rc7 --add-module=/opt/soft/ngx_devel_kit-0.3.0
echo "/usr/local/LuaJIT/lib" >> /etc/ld.so.conf
ldconfig

2、修改配置

    #new
    set $resp_header "";
    header_filter_by_lua '
        local h = ngx.resp.get_headers()
        for k, v in pairs(h) do
        ngx.var.resp_header=ngx.var.resp_header..k..": "..v
        end
    ';

    set $response_body      "";
    body_filter_by_lua      '
        local       response_body = string.sub(ngx.arg[1],1,1000)
        ngx.ctx.buffered =  (ngx.ctx.buffered or "")        ..      response_body
        if ngx.arg[2] then
            ngx.var.response_body = ngx.ctx.buffered
        end
    ';
