一、安装nginx 安装nginx教程就不具体介绍了,网上教程很多,随便搜几个就ok。 二、安装openresty 推荐安装openresty。openresty是一个打包程序,包含大量的第三方Nginx模块,包括lua。咱们现在主要是使用其中的ngx_lua模块来帮助nginx日志记录response。 1、安装openresty依赖 ubuntu安装: # sudo apt-get install libreadline-dev libncurses5-dev libpcre3-dev \ libssl-dev perl make build-essential centos安装: # yum install readline-devel pcre-devel openssl-devel gcc 2、下载openresty源码: # wget http:///download/openresty-1.9.7.4.tar.gz 3、解压 # tar xf openresty-1.9.7.4.tar.gz 4、编译安装 # cdopenresty-1.9.7.4 # ./configure --prefix=/opt/openresty \ --with-luajit \ --without-http_redis2_module \ --with-http_iconv_module # make && make install 此方法本次测试暂时不可用,请参考官方安装文档:http:///cn/linux-packages.html 5、运行测试 -- 1. 修改配置文件如下: $ cat /opt/openresty/nginx/conf/nginx.conf worker_processes 1; error_log logs/error.log info; events { worker_connections 1024; } http { server { listen 8003; location / { content_by_lua 'ngx.say("hello world.")'; } } } -- 2. 启动nginx $ /opt/openresty/nginx/sbin/nginx -- 3. 检查nginx $ curl http://127.0.0.1:8003/ hello world. 三、配置nginx.conf worker_processes 1; error_log logs/error.log info; events { worker_connections 1024; } http { log_format main '$remote_addr | $remote_user | [$time_local] | ' '"$request" | $status | $body_bytes_sent | ' '"$http_referer" | "$http_user_agent" | $request_time | ' '"$request_body" | "$resp_body"'; access_log logs/access.log main; upstream bankend { server 192.168.136.102:9090; server 192.168.136.103:9090; } server { listen 8000; server_name localhost; set $resp_body ""; location / { proxy_pass http://bankend; lua_need_request_body on; body_filter_by_lua ' local resp_body = string.sub(ngx.arg[1], 1, 1000) ngx.ctx.buffered = (ngx.ctx.buffered or "") .. resp_body if ngx.arg[2] then ngx.var.resp_body = ngx.ctx.buffered end '; } } } 四、运行 启动nginx后,发送请求,nginx的日志这个时候已经可以正常记录请求和相应数据了。
