修改nginx日志格式为json

Nginx 日志默认为普通文本的格式

100.116.122.100 - - [/Oct/::: +] "GET /css/bootstrap.css HTTP/1.1"   "https://boss.zbt.com/finance/partner/create-account-gateway?id=529460523813568512" "Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.67 Safari/537.36" "220.191.185.22"

为了便于利用 Elastic Stack 日志平台收集展示 Nginx 的日志，可以将 Nginx 的日志改成 json 的格式。

{"@timestamp": "29/Nov/2018:14:37:45 +0800","user_ip":"-","lan_ip":"100.116.111.202","log_time":"2018-11-29T14:37:45+08:00","user_req":"HEAD / HTTP/1.0","http_code":"","body_bytes_sents":"","req_time":"0.121","user_ua":"-"}

修改 nginx.conf 文件， /etc/nginx/nginx.conf

修改http模块为如下

http {

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

                      '$status $body_bytes_sent "$http_referer" '

                      '"$http_user_agent" "$http_x_forwarded_for" '

                                          '$http_host '

                      ' $upstream_response_time  $request_time  $upstream_addr $geoip_country_code';

    log_format  log_json  '{"@timestamp": "$time_local","user_ip":"$http_x_real_ip","lan_ip":"$remote_addr","log_time":"$time_iso8601","user_req":"$request","http_code":"$status","body_bytes_sents":"$body_bytes_sent","req_time":"$request_time","user_ua":"$http_user_agent"}';

     access_log  /var/log/nginx/access.log  log_json;

有些server单独设置了log的，需要在log后面添加 log_json格式

测试

nginx  -t

重启

nginx  -s reload
