  • 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配置文件中添加下列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 &#39;$remote_addr | $request_body | $resp_body&#39;;

sendfile        on;
keepalive_timeout  65;

server {
    listen       80;
    server_name  localhost;
    charset utf-8;
    set $resp_body &#34;&#34;;
    location / {
        root   /web/;
        index  index.php index.html index.htm;
    }

    location ~* ^/lua(/.*) {
            default_type &#39;text/plain&#39;;
            content_by_lua &#39;ngx.say(&#34;hello, lua&#34;)&#39;;
    }

    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 &#39;
                    local resp_body = string.sub(ngx.arg[1], 1, 1000)
                    ngx.ctx.buffered = (ngx.ctx.buffered or&#34;&#34;) .. resp_body
                    if ngx.arg[2] then
                            ngx.var.resp_body = ngx.ctx.buffered
                    end
              &#39;;
    }
}

}

创建php文件,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

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
