基于nginx打印返回值,此功能在nginx内置的功能中没有,需要安装第三方??閚gx_lua及相关很多??椋绻勇榉城沂导试市?,建议直接卸载掉nginx使用openresty:
如果必须基于nginx来配置,请继续阅读 > > >
1. 安装LuaJIT
此??樾枰狶ua语言,所以需要安装相应的Lua语言包。下载可能很慢,耐心等待。
wget http://luajit.org/download/LuaJIT-2.0.2.tar.gz
tar -xzvf LuaJIT-2.0.2.tar.gz
cd LuaJIT-2.0.2
make
导入环境变量,告诉nginx去哪里找luajit
export LUAJIT_LIB=/usr/local/lib
export LUAJIT_INC=/usr/local/include/luajit-2.0
2. 下载及解压nginx lua模块
作者是解压到/etc/nginx/modules文件夹下,读者按照实际要求,自定义文件夹
cd /etc/nginx/modules
wget https://github.com/openresty/lua-nginx-module/archive/v0.10.9rc7.tar.gz
tar -zxvf v0.10.9rc7.tar.gz
3. 下载及解压nginx devel kit???/h3>
cd /etc/nginx/modules
wget https://github.com/simpl/ngx_devel_kit/archive/v0.3.0.tar.gz
tar -zxvf v0.3.0.tar.gz
4. nginx说明
cd /etc/nginx/modules
wget https://github.com/simpl/ngx_devel_kit/archive/v0.3.0.tar.gz
tar -zxvf v0.3.0.tar.gz
安装nginx,如果是yum安装的,选要在下载nginx源码。否则无法将新增的??楸嘁氲絥ginx中。
下载nginx源码需要跟已经安装好的nginx的版本对应上,示例:
nginx -v
wget http://nginx.org/download/nginx-1.18.0.tar.gz
tar -zxvf nginx-1.18.0.tar.gz
cd nginx-1.18.0/
5. 输入 nginx -V 命令,输入如下:
[root@localhost ~]# nginx -V
nginx version: nginx/1.18.0
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC)
built with OpenSSL 1.0.2k-fips 26 Jan 2017

其中“configure arguments:”之后的内容为当前nginx的??榕渲貌问酉吕葱枰略瞿?榧尤虢?。
6.进入到nginx源码文件夹下,将新的??楸嘁虢?/h3>
可以看到“./configure”后的参数是在之前的“configure arguments:”的基础上,追加了两个“--add-module”
执行如下命令:
./configure --prefix=/etc/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --pid-path=/var/run/nginx.pid --lock-path=/var/run/nginx.lock --http-client-body-temp-path=/var/cache/nginx/client_temp --http-proxy-temp-path=/var/cache/nginx/proxy_temp --http-fastcgi-temp-path=/var/cache/nginx/fastcgi_temp --http-uwsgi-temp-path=/var/cache/nginx/uwsgi_temp --http-scgi-temp-path=/var/cache/nginx/scgi_temp --user=nginx --group=nginx --with-compat --with-file-aio --with-threads --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_mp4_module --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_v2_module --with-mail --with-mail_ssl_module --with-stream --with-stream_realip_module --with-stream_ssl_module --with-stream_ssl_preread_module --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -m64 -mtune=generic -fPIC' --with-ld-opt='-Wl,-z,relro -Wl,-z,now -pie' --add-module=/etc/nginx/modules/ngx_devel_kit-0.2.19 --add-module=/etc/nginx/modules/lua-nginx-module-0.10.2
如果报错,看看报的什么错,作者报的错是少了两个组件:
yum -y install pcre-devel
yum -y install openssl openssl-devel
# 另外还少了一个配置
echo "/usr/local/luajit/lib" >> /etc/ld.so.conf
./configure 命令正确执行之后,重新编译nginx
make -j2
make install
然后重启ng
nginx -s stop
nginx
7. 配置nginx配置文件
修改nginx.conf,在log_format中添加response body的变量[ resp_body:"$resp_body"]
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for" resp_body:"$resp_body" ';
access_log /var/log/nginx/access.log main;
然后server里面赋值:
server {
listen 80;
server_name localhost;
lua_need_request_body on;
set $resp_body "";
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
';
# 根路径
location / {
root /home/temp/;
index index.html index.htm;
}
}
重启ng,验证nginx日志
nginx -s reload
tail -f /var/log/nginx/access.log
输出内容为16进制的字符,需要转换一下才能看实际内容。转换方法略...
