Grafana接入Prometheus实战
操作系统:阿里龙蜥操作系统(AnolisOS-7.9-GA-x86_64)(类似CentOS7.9)
1.安装nginx
nginx下载地址:https://nginx.org/download/nginx-1.28.0.tar.gz
nginx-module-vts下载地址:https://codeload.github.com/vozlt/nginx-module-vts/tar.gz/refs/tags/v0.2.4
本文默认放在“/home”目录下,如下图:
cd /home/nginx_home/nginx-1.28.0# 执行配置文件
./configure --prefix=/usr/local/nginx --with-http_stub_status_module --add-module=/home/nginx_home/nginx-module-vts-0.2.4# 执行make命令
make
make install# 查看Nginx是否存在
whereis nginx
# 查看版本
/usr/local/nginx/sbin/nginx -v
修改配置文件:
检查配置:
cd /usr/local/nginx/conf
/usr/local/nginx/sbin/nginx -t
启动:
cd /usr/local/nginx/sbin
./nginx
查看进程:
netstat -lntp | grep 80
访问统计信息:
http://ip/status
http://10.86.97.201/status
2.安装nginx-vts-exporter
下载地址:https://github.com/sysulq/nginx-vts-exporter/releases
# 解压
tar -xvf nginx-vts-exporter-0.10.3.linux-amd64.tar.gz# 启动
cd /home/nginx_home/nginx-vts-exporter-0.10.3
nohup /home/nginx_home/nginx-vts-exporter-0.10.3/nginx-vts-exporter -nginx.scrape_uri http://10.86.97.201/status/format/json &# 检查
lsof -i:9913
访问:
http://10.86.97.201:9913/metrics
3.接入prometheus
修改配置:
vim /home/prometheus/prometheus.yml- job_name: "nginx-vts"metrics_path: "/metrics"static_configs:- targets: ["10.86.97.201:9913"]
重启prometheus:
lsof -i:9090
kill -9 pid
nohup /home/prometheus/prometheus --config.file="/home/prometheus/prometheus.yml" &
访问:http://10.86.97.200:9090
4.接入grafana
访问grafana:
http://10.86.97.200:3000/
Grafana Dashboard ID: 2949
5.常见问题
①问题:nginx安装,执行./configure报错如下:
./configure: error: C compiler cc is not found
解决:
sudo yum groupinstall “Development Tools”
②问题:nginx安装,执行./configure,报错如下:
./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=
解决:
安装 PCRE 开发库:sudo yum install pcre-devel
③问题:nginx安装,执行./configure,报错如下:
./configure: error: the HTTP gzip module requires the zlib library.
You can either disable the module by using --without-http_gzip_module
option, or install the zlib library into the system, or build the zlib library
statically from the source with nginx by using --with-zlib=
解决:
sudo yum install zlib-devel
④问题:nginx-vtx-exporter启动,报错如下:
./nginx-vtx-exporter: /lib64/libc.so.6: version `GLIBC_2.32’ not found (required by ./nginx-vtx-exporter)
解决:
不要使用最新版本,建议使用nginx-vts-exporter-0.10.3.linux-amd64.tar.gz。
