这套Nginx日志解决方案，真香

Nginx日志

最近客户有个新需求 ， 就是想查看网站的访问情况 ， 由于网站没有做google的统计和百度的统计 ， 所以访问情况 ， 只能通过日志查看 ， 通过脚本的形式给客户导出也不太实际 ， 给客户写个简单的页面 ， 咱也做不到
成熟的日志解决方案 ， 那就是ELK ， 还有现在比较火的Loki ， （当然还有很多其他解决方案 ， 比如Splunk、Datadog等） ， 那我们这个小网站 ， 小体量 ， 必然是选择Loki来做
所以这次就采用Nginx+Promtail+Loki+Grafana来做一个简单的Nginx日志展示

这套Nginx日志解决方案，真香

Nginx的安装不多说 ， Promtail和Loki都选用二进制的方式进行安装 ， 直接下载对应版本的二进制文件 ， 解压后指定配置文件启动即可
其中promtail配置文件如下配置：
