[Prometheus+Grafana+Alertmanager搭建全方位的监控告警系统-超详细文档][Prometheus_Grafana_Alertmanager_-]

在k8s的master节点安装nginx-module-vts模块

**nginx-module-vts-master.zip压缩包所在的百度网盘所在的链接如下：**

链接：https://pan.baidu.com/s/1sG9vuSknc7p7f_AryTrBhw 
    提取码：jf19

**解压软件包**

unzip nginx-module-vts-master.zip
    mv nginx-module-vts-master /usr/local/

安装nginx

**nginx-1.15.7.tar.gz压缩包所在的百度网盘地址如下：**

链接：https://pan.baidu.com/s/1PDAi7eSFJkqejb-RC0tPHg 
    提取码：uhjc

**解压软件包：**

tar zxvf nginx-1.15.7.tar.gz

**预配制**

cd nginx-1.15.7

./configure  --prefix=/usr/local/nginx --with-http_gzip_static_module --with-http_stub_status_module --with-http_ssl_module --with-pcre --with-file-aio --with-http_realip_module --add-module=/usr/local/nginx-module-vts-master

**编译和编译安装**

make && make install

**修改nginx配置文件**

cat  /usr/local/nginx/conf/nginx.conf

server下添加如下：

location /status {
            vhost_traffic_status_display;
            vhost_traffic_status_display_format html;
            }

http中添加如下

vhost_traffic_status_zone;

**测试nginx配置文件是否正确**

/usr/local/nginx/sbin/nginx -t

如果正确没问题，启动nginx

启动nginx：

/usr/local/nginx/sbin/nginx

访问k8s的master节点主机ip/status可以看到nginx监控数据

安装nginx-vts-exporter

**nginx-vts-exporter-0.5.zip压缩包所在的百度网盘地址如下**

链接：https://pan.baidu.com/s/1jKtpyYfU01FiS3E2VuQmfQ 
    提取码：jeps

**解压软件包**

unzip  nginx-vts-exporter-0.5.zip

**启动服务**

mv nginx-vts-exporter-0.5  /usr/local/

chmod +x /usr/local/nginx-vts-exporter-0.5/bin/nginx-vts-exporter

cd /usr/local/nginx-vts-exporter-0.5/bin

nohup ./nginx-vts-exporter  -nginx.scrape_uri http://192.168.124.16/status/format/json &

\#注意：http://192.168.124.16/status/format/json这个地方的ip地址是nginx服务所在主机的IP地址，nginx-vts-exporter的监听端口是9913

修改prometheus-cfg.yaml文件

添加如下job：

\- job\_name: 'nginx'

scrape\_interval: 5s

static\_configs:

\- targets: \['192.168.124.16:9913'\]

kubectl apply -f prometheus-cfg.yaml

kubectl delete -f prometheus-deploy.yaml

kubectl apply -f prometheus-deploy.yaml

\#注意：

- targets: ['192.168.124.16:9913']
    这个ip地址是nginx-vts-exporter程序所在机器的ip地址

在grafana界面导入nginx图表

需要导入nginx-vts-stats\_rev2.json这个文件，所在百度网盘地址如下：
