Loki收集Nginx日志并搭建日志聚合平台

释放双眼,带上耳机,听听看~!
一直想实现对Nginx前端代理的一套系统监控,研究了Nginx自带的vts,发现有一些数据无法直观的进行展示。后面看到Loki可以对Nginx进行数据采集及对应模板展示,本次环境使用Loki采集Nginx日志信息,并进行图表展示

Loki收集Nginx日志并搭建日志聚合平台

依赖组件

  • Nginx vts-model Nginx 监控模块
  • Loki 日志平台
  • Grafana 基础组件
  • GeoIP 将IP转换成国家代码,用于在地图上显示
  • Promtail 采集日志

GeoIP库安装

wget https://d.frps.cn/file/tools/nginx/GeoIP-1.6.12.tar.gz
tar -xzf GeoIP-1.6.12.tar.gz
cd GeoIP-1.6.12
./configure
sudo make
sudo make install
sudo sh -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/geoip.conf'

下载GeoIP nginx模块

cd /opt
#配置文件的模块我这里全都下载在/opt下

wget https://dl.miyuru.lk/geoip/dbip/country/dbip.dat.gz
gzip -d dbip.dat.gz 
mv dbip.dat GeoIP.dat

wget https://dl.miyuru.lk/geoip/dbip/city/dbip.dat.gz
gzip -d dbip.dat.gz
mv dbip.dat GeoIPCity.dat

Nginx vts-model & geoip_module

我这里已经有nginx了,不是新安装部署的,所以采用添加依赖包的方式,将模块添加进去。新安装的可以直接构建依赖包

下载nginx-module-vts模块

wget https://d.frps.cn/file/tools/nginx/model/nginx-module-vts_v0.2.2.zip

解压

 unzip nginx-module-vts_v0.2.2.zip

使用nginx -v,添加新的nginx模块

root@frps:/www/server/nginx/src# nginx -V
nginx version: nginx/1.22.1
built by gcc 9.4.0 (Ubuntu 9.4.0-1ubuntu1~20.04.1)
built with OpenSSL 1.1.1q  5 Jul 2022
TLS SNI support enabled
configure arguments: --user=www --group=www --prefix=/www/server/nginx --add-module=/www/server/nginx/src/ngx_devel_kit --add-module=/www/server/nginx/src/lua_nginx_module --add-module=/www/server/nginx/src/ngx_cache_purge --add-module=/www/server/nginx/src/nginx-sticky-module --with-openssl=/www/server/nginx/src/openssl --with-pcre=pcre-8.43 --with-http_v2_module --with-stream --with-stream_ssl_module --with-stream_ssl_preread_module --with-http_stub_status_module --with-http_ssl_module --with-http_image_filter_module --with-http_gzip_static_module --with-http_gunzip_module --with-ipv6 --with-http_sub_module --with-http_flv_module --with-http_addition_module --with-http_realip_module --with-http_mp4_module --add-module=/www/server/nginx/src/ngx_http_substitutions_filter_module-master --with-ld-opt=-Wl,-E --with-cc-opt=-Wno-error --with-ld-opt=-ljemalloc --with-http_dav_module --add-module=/www/server/nginx/src/nginx-dav-ext-module

在最后一行添加--add-module=/www/server/nginx/src/nginx-module-vts-0.2.2--with-http_geoip_module

开始编译

root@frps:/www/server/nginx/src# ./configure --user=www --group=www --prefix=/www/server/nginx --add-module=/www/server/nginx/src/ngx_devel_kit --add-module=/www/server/nginx/src/lua_nginx_module --add-module=/www/server/nginx/src/ngx_cache_purge --add-module=/www/server/nginx/src/nginx-sticky-module --with-openssl=/www/server/nginx/src/openssl --with-pcre=pcre-8.43 --with-http_v2_module --with-stream --with-stream_ssl_module --with-stream_ssl_preread_module --with-http_stub_status_module --with-http_ssl_module --with-http_image_filter_module --with-http_gzip_static_module --with-http_gunzip_module --with-ipv6 --with-http_sub_module --with-http_flv_module --with-http_addition_module --with-http_realip_module --with-http_mp4_module --add-module=/www/server/nginx/src/ngx_http_substitutions_filter_module-master --with-ld-opt=-Wl,-E --with-cc-opt=-Wno-error --with-ld-opt=-ljemalloc --with-http_dav_module --add-module=/www/server/nginx/src/nginx-dav-ext-module --add-module=/www/server/nginx/src/nginx-module-vts-0.2.2 --with-http_geoip_module

我们只需要执行make就可以

root@frps:/www/server/nginx/src# make

替换nginx二进制包

root@frps:/www/server/nginx/src# nginx -s stop
root@frps:/www/server/nginx/src# cp objs/nginx /www/server/nginx/sbin/nginx

接下来,我们在最后两行就可以看到新增的模块

root@frps:/www/server/nginx/src# nginx -V
nginx version: nginx/1.22.1
built by gcc 9.4.0 (Ubuntu 9.4.0-1ubuntu1~20.04.1)
built with OpenSSL 1.1.1q  5 Jul 2022
TLS SNI support enabled
configure arguments: --user=www --group=www --prefix=/www/server/nginx --add-module=/www/server/nginx/src/ngx_devel_kit --add-module=/www/server/nginx/src/lua_nginx_module --add-module=/www/server/nginx/src/ngx_cache_purge --add-module=/www/server/nginx/src/nginx-sticky-module --with-openssl=/www/server/nginx/src/openssl --with-pcre=pcre-8.43 --with-http_v2_module --with-stream --with-stream_ssl_module --with-stream_ssl_preread_module --with-http_stub_status_module --with-http_ssl_module --with-http_image_filter_module --with-http_gzip_static_module --with-http_gunzip_module --with-ipv6 --with-http_sub_module --with-http_flv_module --with-http_addition_module --with-http_realip_module --with-http_mp4_module --add-module=/www/server/nginx/src/ngx_http_substitutions_filter_module-master --with-ld-opt=-Wl,-E --with-cc-opt=-Wno-error --with-ld-opt=-ljemalloc --with-http_dav_module --add-module=/www/server/nginx/src/nginx-dav-ext-module --add-module=/www/server/nginx/src/nginx-module-vts-0.2.2 --with-http_geoip_module

模块安装完毕后,我们需要配置模块

修改nginx配置文件

http标签下添加

geoip_country /opt/GeoIP.dat;
geoip_city /opt/GeoIPCity.dat;

 access_log logs/json_access.log json_analytics;

添加完毕后我们最好重启一下nginx

Loki 安装配置

mkdir -p /opt/loki/chunks
chmod -R 777 /opt/loki   #需要设置权限,否则索引创建失败

启动Loki服务

docker run -d \
--name loki \
--privileged=true \
-v /opt/loki:/mnt/config \
-v /opt/loki/index:/opt/loki/index \
-v /opt/loki/chunks:/opt/loki/chunks \
-p 3100:3100 \
-p 9096:9096 \
grafana/loki:2.1.0 -config.file=/mnt/config/loki-config.yaml

测试

root@frps:/opt# curl localhost:3100/loki/api/v1/labels
{"status":"success","data":["__name__"]}

Promtail 配置

Promtail 是负责收集日志发送给 loki 的代理程序,Promtail 默认通过一个 config.yaml 文件进行配置,其中包含 Promtail 服务端信息、存储位置以及如何从文件中抓取日志等配置。

我们需要在需要收集日志的节点配置Promtail

cat >>promtail-config.yaml<<EOF
server:
  http_listen_port: 9080
  grpc_listen_port: 0

positions:
  filename: /tmp/positions.yaml

clients:
  - url: http://10.0.24.9:3100/loki/api/v1/push

scrape_configs:
- job_name: nginx
  static_configs:
  - targets:
      - localhost
    labels:
      job: nginxlogs
      __path__: /var/log/json_account.log
EOF
  • 10.0.24.9 ip需要修改为Loki的ip
  • 这里我建议写一个日志文件,也可以写多个

启动容器

docker run -d --name promtail \
  -v /www/wwwlogs:/var/log \
  -v /opt/config:/mnt/config \
  grafana/promtail \
  -config.file=/mnt/config/promtail-config.yaml

Grafana 配置

筛选日志

  • 出来日志路径基本上可以确认是可以获取到日志了

下面我们就可以看到日志了

新版本的不建议直接使用ID 12559 初次尝试发现数据有问题,采用下载旧版本在上传的方式

如果导入数据有问题,等待几分钟后在重新导入一遍模板就可以了

    启动容器

    docker run -d –name promtail
    -v /www/wwwlogs:/var/log
    -v /opt/config:/mnt/config
    grafana/promtail
    -config.file=/mnt/config/promtail-config.yaml

    一直无法解析这个配置文件

  2. Seven~

    容器日志: {“log”:”Unable to parse config: /mnt/config/promtail-config.yaml does not exist, set config.file for custom config pathn”,”stream”:”stdout”,”time”:”2023-11-10T03:48:40.961624273Z”}

    • Seven~

      /mnt/config/promtail-config.yaml 我是有这个文件的

    • Seven~

      没有其他报错了,就只是文件解析错误 我已经下载了官方的文件然后进行修改解决了 但是grafana可视化太多报错了
