优化企业网站模板做明星同款的网站

一、需要监控进程的服务器上配置
1、进入到临时工作目录，传入process_exporter包
[root@ Nginx1 ~]# cd work/
[root@ Nginx1 work]# rz
2、解压，并移动至/usr/local/目录下
[root@ Nginx1 work]# tar xzf process-exporter-0.7.5.linux-amd64.tar.gz
[root@ Nginx1 work]# mv process-exporter-0.7.5.linux-amd64 process-exporter-0.7.5
[root@ Nginx1 work]# mv process-exporter-0.7.5 /usr/local/
[root@ Nginx1 work]# cd /usr/local/
[root@ Nginx1 local]# ln -s process-exporter-0.7.5/ process-exporter
[root@ Nginx1 local]# cd process-exporter
3、写配置文件
[root@ Nginx1 process-exporter]# vi nginx.yaml

process_names:- name: "{{.Matches}}"cmdline:
- '/usr/local/nginx/sbin/nginx' （需监控的进程名字）

4、编写启动服务文件
[root@ Nginx1 process-exporter]# cd /etc/systemd/system/
[root@ Nginx1 system]# vi process_exporter.service

[Unit]
Description=Prometheus exporter for processors metrics, written in Go with pluggable metric collectors.
Documentation=https://github.com/ncabatoff/process-exporter-0.7.5
After=network.target[Service]
Type=simple
User=root
Group=root
WorkingDirectory=/usr/local/process-exporter
ExecStart=/usr/local/process-exporter/process-exporter  --config.path=/usr/local/process-exporter/nginx.yaml
Restart=on-failure
[Install]
WantedBy=multi-user.target

5、启动服务，并设置开机自启
[root@ Nginx1 system]# systemctl daemon-reload
[root@ Nginx1 system]# systemctl start process_exporter.service
[root@ Nginx1 system]# systemctl status process_exporter.service
[root@ Nginx1 system]# systemctl enable process_exporter
6、防火墙开启端口
[root@ Nginx1 system]# firewall-cmd --permanent --add-rich-rule=“rule family=“ipv4” source address=” 192.168.1.11" port port=“9256” protocol=“tcp” accept"
[root@ Nginx1 system]# firewall-cmd --reload
二、监控服务器上配置
1、编写配置文件
[root@dy-prometheus ~]# cd /usr/local/prometheus
[root@dy-prometheus prometheus]# vi scrapetarget.json

  {"targets": ["192.168.1.11:9256" ], （需要监控的主机IP）"labels": {"os": "Linux","region": "test","middleware": "nginx1_process"  （监控进程名，可自定义）}},{"targets": ["192.168.1.12:9256" ],"labels": {"os": "Linux","region": "test","middleware": "nginx2_process"}}

2、重启prometheus服务
[root@dy-prometheus prometheus]# systemctl restart prometheus
3、网页上查找相关数据
