1.安裝Docker
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{"registry-mirrors":["https://hub-mirror.c.163.com"]
}
EOFexport DOWNLOAD_URL="https://hub-mirror.163.com/docker-ce"curl -fsSL https://get.docker.com/ |sh檢查docker版本查看是否安裝成功
docker -v安裝Docker-compose
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose檢查版本
docker-compose -v
2.安裝prometheus
通過克隆gitee的代碼來進行安裝Prometheus
因為docker-compose安裝Prometheus需要進行大量的配置,這里推薦直接從gitee上克隆已經配置好的docker-compose文件
mkdir /datacd /datagit clone https://gitee.com/linge365/docker-prometheus.gitcd docker-prometheus當然以上這一步需要安裝git,也可以直接訪問https://gitee.com/linge365/docker-prometheus.git 下載對應的壓縮包,解壓后移動到/data目錄下即可
運行prometheus
運行命令
cd /data/docker-prometheusdocker-compose up -d檢查是否運行成功
查看正在運行的docker容器
docker ps[root@node1 bak]# docker ps

到這里對應的容器就全部啟動了,這里需要將對應的端口開放進行訪問(云服務器需要開放對應的安全組或者防火墻),然后通過服務器ip+端口號在瀏覽器中即可訪問.(很重要)
web訪問地址
| 應用 | 訪問地址 | 備注 |
|---|---|---|
| prometheus | http://127.0.0.1:9090 | 無用戶和密碼 |
| grafana | http://127.0.0.1:3000 | admin/XXX |
| altermanager | http://127.0.0.1:9093 | 無用戶和密碼 |
| node-exporter | http://127.0.0.1:9100/metrics | 無用戶和密碼 |
遇到問題了，我再本機可以訪問這些端口，但是再其他機器上無法訪問端口，
1.防火墻攔截
??查看防火墻狀態firewall-cmd --state
? 關閉防火墻systemctl stop firewalld.service
? 禁止防火墻開機啟動systemctl disable firewalld.service
? 或者打開防火墻，但防火墻開放映射的端口
? firewall-cmd --zone=public --add-port=3000/tcp --permanent
? firewall-cmd --zone=public --add-port=9000/tcp --permanent
? firewall-cmd --zone=public --add-port=9090/tcp --permanent
? firewall-cmd --zone=public --add-port=9100/tcp --permanent 等等
2.沒有開啟ip轉發
? 查看是否開啟
# 1.查看是否開啟，若不等于1則沒有開啟
sysctl net.ipv4.ip_forward
# 2.修改sysctl.conf文件開啟
vim /etc/sysctl.conf
# 3，配置=1
net.ipv4.ip_forward=1
# 4. 重啟網絡，讓配置生效
systemctl restart network
# 5.再次查看是否等于1
sysctl net.ipv4.ip_forward
3.做完上述操作，一定要systemctl restart docker? 。否則也不會好使。
3.檢查各個端口程序
3.1grafana
這里grafana的配置文件中默認配置的密碼為password,所以直接輸入admin/password即可訪問成功.
添加數據源
在下方齒輪圖標選擇添加數據源
選擇Prometheus作為數據源
填寫Prometheus的地址,這里的ip需要將服務名作為地址填寫在URL中 我填寫的內容是http://10.23.3.2:9090
下滑到最下方測試并保存
導入儀表盤
選擇左邊儀表盤圖標點擊導入
這里需要導入一個儀表盤的URL或者id
我填寫的是1860
也可以直接訪問https://grafana.com/grafana/dashboards/路徑進入官網進行復制,直接選擇Node Exproter Full
選擇Copy ID
然后粘貼到剛剛的輸入框中,點擊加載(Load)按鈕
然后選擇Prometheus作為數據源
點擊導入,即可進入儀表盤界面
8919的界面
16098? job分組的
添加精簡導出器
我這邊根據網絡上面的dashardboard進行修改，使用在工作中的dashboard如下圖。
在import中不輸入1860，而是在下面json中輸入一下內容

}3.2 prometheus界面使用
訪問http://10.23.3.2:9090/
查看監控主機列表
點擊status—targets
可以看剛安裝好的prometheus只有自己服務器的監控
查看監控指標
點擊圖中的endpoint下面的鏈接即可
于圖中的鏈接是localhost，我們點開后會報錯的，
因此我們需要填寫正真的prometheus的ip地址才能看到監控指標頁面
http://10.23.3.2:9090/metrics
解決監控指標頁面為localhost問題
/home/prometheus/docker-prometheus/prometheus
1.修改主配置文件prometheus.yml
[root@prometheus-server prometheus]# vim prometheus.yml - job_name: 'prometheus'# metrics_path defaults to '/metrics'# scheme defaults to 'http'.static_configs:- targets: ['192.168.81.250:9090'] #將這里的ip由localhost改為prometheus的真實ip2.重啟prometheus
[root@node1 prometheus]# docker ps

我們看到已經不是localhost或是其他的了，點開即可查看
3.3?安裝node_exporter組件監控Linux主機
在主機10.23.3.1（linux）
wget https://github.com/prometheus/node_exporter/releases/download/v1.0.1/node_exporter-1.0.1.linux-amd64.tar.gz
mkdir /data
tar -xvf node_exporter-1.0.1.linux-amd64.tar.gz -C /data
cd /data
mv node_exporter-1.0.1.linux-amd64 node_exporter
cd node_exporter/
nohup /data/node_exporter/node_exporter &
netstat -anp | grep 9100安裝好node_exporter后訪問本機9100端口下的metrics目錄即可看到監控數據
http://10.23.3.1:9100/metrics
在prometheus-server上添加監控主機
我們在本機開啟node_exporter后需要在prometheus server上進行配置，最終實現在prometheus頁面看到監控主機的信息
1.配置prometheus
[root@prometheus-server ~]# cd /data/prometheus/
[root@prometheus-server prometheus]# vim prometheus.yml - job_name: "10.23.3.1"static_configs:- targets: ['10.23.3.1:9100'] 2.重啟prometheus
[root@prometheus-server prometheus]# ps aux | grep prometheus | awk '{print $2}' | xargs kill -9
[root@prometheus-server prometheus]# ./prometheus --config.file="/data/prometheus/prometheus.yml" &解釋：
job_name: "linux3.1"#起一個監控主機的名稱，我們這里以ip地址為名targets: ['10.23.3.1:9100'] #監控主機的地址重啟prometheus容器
[root@node1 prometheus]# docker ps

[root@node1 prometheus]# docker restart 69256ba5c47e查看prometheus頁面是否添加主機
點擊status—targets
成功添加
擴展：prometheus添加分組主機
在監控主機安裝node_exporter
我們有10.23.2.3、10.23.3.4兩臺主機，可以將這兩臺主機添加到一個組里面
分別在這兩臺上安裝node_exporter
兩臺都執行以下操作
1.安裝node_exporter
[root@grafana ~]# tar xf node_exporter-1.0.1.linux-amd64.tar.gz -C /data
[root@grafana ~]# cd /data
[root@grafana data]# mv node_exporter-1.0.1.linux-amd64/ node_exporter2.啟動node_exporter
[root@grafana data]# cd node_exporter
[root@grafana node_exporter]# nohup /data/node_exporter/node_exporter &3.查看端口
[root@grafana node_exporter]# netstat -lnpt | grep 9100
配置prometheus
[root@node1 prometheus]# pwd
/home/prometheus/docker-prometheus/prometheusvim prometheus.yml?- job_name: "Tomcat"static_configs:- targets: ['10.23.3.3:9100']- targets: ['10.23.3.4:9100']注釋：當job_name下面有多個targets時，則當前job_name不再是一臺主機的名稱，而是下面所有targets的名稱，也就是分組名頁面添加主機分組成功
