    • 1. 软件版本

    • 系统 centos6.7X86_64
    • nginx 1.11.5
    • lua-nginx-module 0.10.7
    • PHP 5.6.27

    2. 环境准备

    配置yum仓库

    wget -O /etc/yum.repos.d/CentOS-Base.repo[https://lug.ustc.edu.cn/wiki/_export/code/mirrors/help/centos?codeblock=2](https://lug.ustc.edu.cn/wiki/_export/code/mirrors/help/centos?codeblock=2)
wget -O /etc/yum.repos.d/epel.repo[https://lug.ustc.edu.cn/wiki/_export/code/mirrors/help/epel?codeblock=0](https://lug.ustc.edu.cn/wiki/_export/code/mirrors/help/epel?codeblock=0)
wget -O /etc/yum.repos.d/epel-testing.repo[https://lug.ustc.edu.cn/wiki/_export/code/mirrors/help/epel?codeblock=1](https://lug.ustc.edu.cn/wiki/_export/code/mirrors/help/epel?codeblock=1)
/usr/sbin/ntpdate  asia.pool.ntp.org

    安装编译所需的依赖

    yum -y install gcc gcc-c++ make libtool zlib zlib-devel openssl openssl-devel pcre  pcre-devel

    3. 软件安装

    安装php5.6

    rpm -Uvh https://mirror.webtatic.com/yum/el6/latest.rpm
yum -y install php56w-cli php56w-mysql php56w-xml php56w-mbstring php56w-pdo php56w-bcmath php56w-mcrypt php56w-fpm

    编译安装nginx

    cd /opt/software/
wget https://codeload.github.com/openresty/lua-nginx-module/tar.gz/v0.10.7
wget http://luajit.org/download/LuaJIT-2.0.4.tar.gz
wget https://nginx.org/download/nginx-1.11.5.tar.gz

    groupadd nginx
    
useradd -g nginx -s /sbin/nologin nginx
    
mkdir -p /var/tmp/nginx/client/
    
mkdir -p /usr/local/nginx
    

    tar zxf v0.10.7
    
tar zxf LuaJIT-2.0.4.tar.gz
    
tar zxf nginx-1.11.5.tar.gz
    

    cd LuaJIT-2.0.4/
    
make && make install
    

    cat >> /etc/profile <<EOF
    
export LUAJIT_LIB=/usr/local/lib
    
export LUAJIT_INC=/usr/local/include/luajit-2.0
    
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
    
EOF
    
source /etc/profile
    

    cd …/nginx-1.11.5/
    
./configure   --prefix=/usr/local/nginx   --user=nginx   --group=nginx   --with-http_ssl_module   --with-http_flv_module   --with-http_stub_status_module   --with-http_gzip_static_module   --with-http_realip_module   --http-client-body-temp-path=/var/tmp/nginx/client/   --http-proxy-temp-path=/var/tmp/nginx/proxy/   --http-fastcgi-temp-path=/var/tmp/nginx/fcgi/   --http-uwsgi-temp-path=/var/tmp/nginx/uwsgi   --http-scgi-temp-path=/var/tmp/nginx/scgi   --with-pcre --add-module=…/lua-nginx-module-0.10.7
    

    make -j2
    
make install

    4. 配置lua脚本

    在nginx配置文档中添加下列location

    # /usr/local/nginx/conf/nginx.conf
        location ~* ^/lua(/.*) {
                default_type 'text/plain';
                content_by_lua 'ngx.say("hello, lua")';
        }

    启动nginx

    /usr/local/nginx/sbin/nginx

    测试lua脚本执行

    curl http://127.0.0.1/lua/

    返回 hello, lua 为正常

    5. 配置php

    启用如下选项

    #/usr/local/nginx/conf/nginx.conf
location / {
            root   /web;
            index  index.php index.html index.htm;
        }

    location ~ .php$ {
    
root           /web/;
    
fastcgi_pass   127.0.0.1:9000;
    
fastcgi_index  index.php;
    
fastcgi_param  SCRIPT_FILENAME  /documentrootdocument_rootfastcgi_script_name;
    
include        fastcgi_params;
    
}

    在/web/目录下 新建index.php的测试页面，测试php是否能正常工作

    mkdir /web/
cat > /web/info.php << EOF
<?php
phpinfo();
?>
EOF
chown nginx.nginx -R /web/

    启动php-fpm和nginx

    /etc/init.d/php-fpm start
/usr/local/nginx/sbin/nginx  -s reload

    测试

    curl http://127.0.0.1/info.php

    显示phpinfo页面，极为正常

    6. 配置日志，记录post请求的request_body 和response_body

    使用下列配置

    # /usr/local/nginx/conf/nginx.conf
user  nginx;
worker_processes  1;

    events {
    
worker_connections  1024;
    
}
    

    http {
    
include       mime.types;
    
default_type  application/octet-stream;
    

    log_format postdata '$remote_addr | $request_body | $resp_body';

sendfile        on;
keepalive_timeout  65;

server {
    listen       80;
    server_name  localhost;
    charset utf-8;
    set $resp_body "";
    location / {
        root   /web/;
        index  index.php index.html index.htm;
    }

    location ~* ^/lua(/.*) {
            default_type 'text/plain';
            content_by_lua 'ngx.say("hello, lua")';
    }

    location ~ .php$ {
                root           /web/;
                fastcgi_pass   127.0.0.1:9000;
                fastcgi_index  index.php;
                fastcgi_param  SCRIPT_FILENAME  /$document_root$fastcgi_script_name;
                include        fastcgi_params;
                access_log /tmp/nginx_access.log postdata;
                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
              ';
    }
}

    

    }

    创建php文档，用来接收post请求，并返回数据

    cat >> /web/index.php  <<EOF
<?php
  header("Content-type:text/html;charset=utf-8"); 
  print_r(file_get_contents('php://input'));
?>
EOF
chown nginx.nginx /web/index.php

    重启nginx

    /usr/local/nginx/sbin/nginx  -s reload

    使用postman工具来发送post请求

    Paste_Image.png

    查看日志

    cat  /tmp/nginx_access.log

    Paste_Image.png

    已经记录post请求的request 和response数据了。

    第二行是因为post数据有中文字符，所以变成了16进制。解决方法见 解决nginx在记录post数据时 中文字符转成16进制的问题
