Docker 部署 Prometheus的安裝詳細(xì)教程
發(fā)布日期：2021-12-13 17:25 | 文章來源：gibhub
Docker 部署 Prometheus 說明：
監(jiān)控端安裝：
Prometheus Server(普羅米修斯監(jiān)控主服務(wù)器 )
Node Exporter (收集Host硬件和操作系統(tǒng)信息)
cAdvisor (負(fù)責(zé)收集Host上運(yùn)行的容器信息)
Grafana (展示普羅米修斯監(jiān)控界面）
被監(jiān)控安裝：
Node Exporter (收集Host硬件和操作系統(tǒng)信息)
cAdvisor (負(fù)責(zé)收集Host上運(yùn)行的容器信息)
1.安裝Node Exporter
- 所有服務(wù)器安裝
- Node Exporter 收集系統(tǒng)信息，用于監(jiān)控CPU、內(nèi)存、磁盤使用率、磁盤讀寫等系統(tǒng)信息
- –net=host，這樣 Prometheus Server 可以直接與 Node Exporter 通信
docker run -d -p 9100:9100 \ -v "/proc:/host/proc" \ -v "/sys:/host/sys" \ -v "/:/rootfs" \ -v "/etc/localtime:/etc/localtime" \ --net=host \ prom/node-exporter \ --path.procfs /host/proc \ --path.sysfs /host/sys \ --collector.filesystem.ignored-mount-points "^/(sys|proc|dev|host|etc)($|/)" [root@k8s-m1 ~]# docker ps|grep exporter ee30add8d207 prom/node-exporter "/bin/node_exporter …" About a minute ago Up About a minute condescending_shirley
2.安裝cAdvisor
- 所有服務(wù)器安裝
- cAdvisor 收集docker信息，用于展示docker的cpu、內(nèi)存、上傳下載等信息
- –net=host，這樣 Prometheus Server 可以直接與 cAdvisor 通信
docker run -d \ -v "/etc/localtime:/etc/localtime" \ --volume=/:/rootfs:ro \ --volume=/var/run:/var/run:rw \ --volume=/sys:/sys:ro \ --volume=/var/lib/docker/:/var/lib/docker:ro \ --volume=/dev/disk/:/dev/disk:ro \ --publish=18104:8080 \ --detach=true \ --name=cadvisor \ --privileged=true \ google/cadvisor:latest [root@k8s-m1 ~]# docker ps|grep cadvisor cf6af6118055 google/cadvisor:latest"/usr/bin/cadvisor -…" 38 seconds ago Up 37 seconds 0.0.0.0:18104->8080/tcp cadvisor
可以進(jìn)入容器查看： [root@agent ~]# sudo docker exec -it 容器id /bin/sh
3.安裝 Prometheus Server
監(jiān)控端安裝
1）編輯配置文件
- 首先在本地創(chuàng)建 prometheus.yml 這是普羅米修斯的配置文件
- 將下方內(nèi)容寫入到文件中
- 將監(jiān)聽的地址改為自己本機(jī)地址
# my global config
global:
scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
# scrape_timeout is set to the global default (10s).
# Alertmanager configuration
alerting:
alertmanagers:
- static_configs:
- targets:
# - alertmanager:9093
# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
# - "first_rules.yml"
# - "second_rules.yml"
# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
- job_name: 'prometheus'
# metrics_path defaults to '/metrics'
# scheme defaults to 'http'.
static_configs:
#監(jiān)聽的地址
- targets: ['localhost:9090','172.23.0.241:8088','172.23.0.241:9090']
2）啟動(dòng)容器
1> prometheus.yml配置文件
prometheus.yml內(nèi)需配置外網(wǎng)ip，內(nèi)網(wǎng)ip除了本機(jī)，在grafana識(shí)別不到！
# my global confi
global:
scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
# scrape_timeout is set to the global default (10s).
# Alertmanager configuration
alerting:
alertmanagers:
- static_configs:
- targets:
# - alertmanager:9093
# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
# - "first_rules.yml"
# - "second_rules.yml"
# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
- job_name: 'prometheus'
# metrics_path defaults to '/metrics'
# scheme defaults to 'http'.
static_configs:
#監(jiān)聽的地址（此處為服務(wù)器內(nèi)網(wǎng)ip）
- targets: ['10.27.158.33:9090','10.27.158.33:9100','10.27.158.33:18104']
- targets: ['10.29.46.54:9100','10.29.46.54:18104']
- targets: ['10.27.163.172:9100','10.27.163.172:18104']
# - job_name: 'GitLab'
# metrics_path: '/-/metrics'
# static_configs:
# - targets: ['172.23.0.241:10101']
- job_name: 'jenkins'
metrics_path: '/prometheus/'
scheme: http
bearer_token: bearer_token
static_configs:
- targets: ['172.23.0.242:8080']
- job_name: "Nginx"
metrics_path: '/status/format/prometheus'
static_configs:
- targets: ['172.23.0.242:8088']
2>啟動(dòng)命令
–net=host，這樣 Prometheus Server 可以直接與 Exporter 和 Grafana 通
docker run -d -p 9090:9090 \ -v /root/Prometheus/prometheus.yml:/etc/prometheus/prometheus.yml \ -v "/etc/localtime:/etc/localtime" \ --name prometheus \ --net=host \ prom/prometheus:latest # 當(dāng)Prometheus容器啟動(dòng)成功后訪問 # PS：服務(wù)器需開啟eth0的外網(wǎng)端口，才可用瀏覽器訪問 9090 0.0.0.0 106.15.0.11:9090
4.創(chuàng)建運(yùn)行Grafana
- 監(jiān)控服務(wù)器安裝
- 用于圖像化顯示
docker run -d -i -p 3000:3000 \ -v "/etc/localtime:/etc/localtime" \ -e "GF_SERVER_ROOT_URL=http://grafana.server.name" \ -e "GF_SECURITY_ADMIN_PASSWORD=admin8888" \ --net=host \ grafana/grafana # PS：服務(wù)器需開啟eth0的外網(wǎng)端口，才可用瀏覽器訪問：3000 0.0.0.0 Grafana啟動(dòng)后，在瀏覽器中打開 172.23.0.241:3000 登錄界面，登錄： 用戶名：admin 密碼：admin8888
1）添加普羅米修斯服務(wù)器
然后為添加好的數(shù)據(jù)源做圖形顯示
5.添加監(jiān)控模板
- 自己手工創(chuàng)建dashboard有點(diǎn)困難，可以借助開元的力量訪問 [監(jiān)控模板地址]https://grafana.com/grafana/dashboards將會(huì)看到很多用于監(jiān)控 Docker 的 Dashboard。監(jiān)控模板地址(多種監(jiān)控模板根據(jù)自己需求下載不同的模板)
- 監(jiān)控模板地址
- 有些dashboard可以下載后直接導(dǎo)入，而有些需要修改后再導(dǎo)入，需要看dashboard的overview
- 最后效果
這時(shí)候可以自己選擇編譯對(duì)應(yīng)的模板，在prometheus上取值
傳到grafana上。就可以了。挺好用的！
6.鍵值查詢
通過指標(biāo) io_namespace_http_requests_total 我們可以：
查詢應(yīng)用的請(qǐng)求總量 sum(io_namespace_http_requests_total) 查詢每秒Http請(qǐng)求量 sum(rate(io_wise2c_gateway_requests_total[5m])) 查詢當(dāng)前應(yīng)用請(qǐng)求量Top N的URI topk(10, sum(io_namespace_http_requests_total) by (path))
配置Prometheus監(jiān)控Nginx
1、需給Nginx安裝兩個(gè)模塊，才可用Prometheus來監(jiān)控：nginx-module-vts、geoip
2、思路：原來無論是編譯、還是yum裝的nginx，都需要下載同版本的tar包，基于原來安裝選項(xiàng)的基礎(chǔ)上，增加以上兩個(gè)模塊選項(xiàng)，進(jìn)行編譯安裝，來替換原來的nginx，最終將原nginx目錄的配置文件如nginx.conf文件、conf.d目錄再移動(dòng)到編譯安裝后的nignx目錄內(nèi)，最后啟動(dòng)nginx即可。
這里官方源安裝：
1）配置官方源
[root@web01 ~]# vim /etc/yum.repos.d/nginx.repo [nginx-stable] name=nginx stable repo baseurl=http://nginx.org/packages/centos/7/$basearch/ gpgcheck=1 enabled=1 gpgkey=https://nginx.org/keys/nginx_signing.key module_hotfixes=true
2）安裝依賴
yum install -y gcc gcc-c++ autoconf pcre pcre-devel make automake wget httpd-tools vim tree
3）安裝nginx
[root@web01 ~]# yum install -y nginx
4）配置nginx
[root@web01 ~]# vim /etc/nginx/nginx.conf user www;
5）啟動(dòng)服務(wù)
1.方法一：直接啟動(dòng)如果有報(bào)錯(cuò)==》重大錯(cuò)誤，80端口有占用==》查看占用端口的服務(wù)HTTPD，停掉，在重啟nginx [root@web01 ~]# systemctl start nginx 2.方法二： [root@web01 ~]# nginx
1.查看當(dāng)前Nginx安裝選項(xiàng)
[root@db01 nginx-1.12.2]# nginx -V [root@db01 nginx-1.12.2]# ./configure --prefix=/usr/share/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --http-client-body-temp-path=/var/lib/nginx/tmp/client_body --http-proxy-temp-path=/var/lib/nginx/tmp/proxy --http-fastcgi-temp-path=/var/lib/nginx/tmp/fastcgi --http-uwsgi-temp-path=/var/lib/nginx/tmp/uwsgi --http-scgi-temp-path=/var/lib/nginx/tmp/scgi --pid-path=/run/nginx.pid --lock-path=/run/lock/subsys/nginx --user=nginx --group=nginx --with-compat --with-debug --with-file-aio --with-google_perftools_module --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_degradation_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_image_filter_module=dynamic --with-http_mp4_module --with-http_perl_module=dynamic --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_v2_module --with-http_xslt_module=dynamic --with-mail=dynamic --with-mail_ssl_module --with-pcre --with-pcre-jit --with-stream=dynamic --with-stream_ssl_module --with-stream_ssl_preread_module --with-threads --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic' --with-ld-opt='-Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -Wl,-E'
2.準(zhǔn)備模塊
# 下載、解壓新包 [root@k8s-n1 packages]# wget http://nginx.org/download/nginx-1.16.1.tar.gz [root@k8s-n1 packages]# tar xf nginx-1.16.1.tar.gz #克隆下載 nginx-module-vts 模塊 [root@k8s-n1 packages]# git clone https://github.com/vozlt/nginx-module-vts # .安裝GeoIP模塊 [root@k8s-n1 packages]# yum -y install epel-release geoip-devel
3.停止Nginx服務(wù)
# 停止nginx服務(wù) [root@k8s-n1 packages]# nginx -s stop # 備份原nginx啟動(dòng)文件 [root@k8s-n1 packages]# which nginx /usr/sbin/nginx [root@k8s-n1 packages]# mv /usr/sbin/nginx /usr/sbin/nginx.bak # 備份原nignx目錄 [root@k8s-n1 packages]# mv /etc/nginx nginx-1.12.2.bak
4.編譯安裝
1> 安裝所需依賴
編譯安裝時(shí)可能會(huì)出現(xiàn) `make: *** 沒有規(guī)則可以創(chuàng)建“default”需要的目標(biāo)“build”。 停止`的報(bào)錯(cuò)，是因?yàn)槿鄙僖蕾噷?dǎo)致 # 管他三七21，裝一波兒在進(jìn)行編譯，否則裝完依賴還得重新./configure ~ yum install -y gcc gcc++ bash-completion vim lrzsz wget expect net-tools nc nmap tree dos2unix htop iftop iotop unzip telnet sl psmisc nethogs glances bc pcre-devel zlib zlib-devel openssl openssl-devel libxml2 libxml2-dev libxslt-devel gd gd-devel perl-devel perl-ExtUtils-Embed GeoIP GeoIP-devel GeoIP-data pcre-devel
2> 編譯安裝
- 進(jìn)入剛剛解壓的nginx目錄，編譯安裝
- 基于原來安裝參數(shù)，尾部追加連個(gè)參數(shù)
–add-module=/root/packages/nginx-module-vts
–with-http_geoip_module
[root@db01 nginx-1.12.2]# ./configure --prefix=/usr/share/nginx --sbin-path=/usr/sbin/nginx --modules-path=/usr/lib64/nginx/modules --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --http-client-body-temp-path=/var/lib/nginx/tmp/client_body --http-proxy-temp-path=/var/lib/nginx/tmp/proxy --http-fastcgi-temp-path=/var/lib/nginx/tmp/fastcgi --http-uwsgi-temp-path=/var/lib/nginx/tmp/uwsgi --http-scgi-temp-path=/var/lib/nginx/tmp/scgi --pid-path=/run/nginx.pid --lock-path=/run/lock/subsys/nginx --user=nginx --group=nginx --with-compat --with-debug --with-file-aio --with-google_perftools_module --with-http_addition_module --with-http_auth_request_module --with-http_dav_module --with-http_degradation_module --with-http_flv_module --with-http_gunzip_module --with-http_gzip_static_module --with-http_image_filter_module=dynamic --with-http_mp4_module --with-http_perl_module=dynamic --with-http_random_index_module --with-http_realip_module --with-http_secure_link_module --with-http_slice_module --with-http_ssl_module --with-http_stub_status_module --with-http_sub_module --with-http_v2_module --with-http_xslt_module=dynamic --with-mail=dynamic --with-mail_ssl_module --with-pcre --with-pcre-jit --with-stream=dynamic --with-stream_ssl_module --with-stream_ssl_preread_module --with-threads --with-cc-opt='-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector-strong --param=ssp-buffer-size=4 -grecord-gcc-switches -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -m64 -mtune=generic' --with-ld-opt='-Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld -Wl,-E' --add-module=/root/package/nginx-module-vts --with-http_geoip_module
# 編譯安裝 # -j 多核編譯（配置低的不建議使用此參數(shù)，會(huì)卡住~） [root@k8s-n1 nginx-1.12.2]# make -j && make install
5.配置Nginx
[root@k8s-n1 packages]# cp -r nginx-1.12.2.bak/conf.d/ /etc/nginx/ [root@k8s-n1 packages]# cp -r nginx-1.12.2.bak/nginx.conf /etc/nginx/ [root@k8s-n1 packages]# rm -f /etc/nginx/conf.d/default.conf
配置Nginx配置文件

6.啟動(dòng)Nginx
[root@k8s-n1 packages]# nginx [root@k8s-n1 packages]# netstat -lntp|grep nginx tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 62214/nginx: master tcp 0 0 0.0.0.0:8088 0.0.0.0:* LISTEN 62214/nginx: master 瀏覽器訪問： 172.23.0.243:80 # nginx 默認(rèn)官方頁面 172.23.0.243:8088/status # nignx 監(jiān)控項(xiàng)頁面
7.使用Prometheus監(jiān)控
- prometheus服務(wù)端配置prometheus.yml，并重啟prometheus容器
- metrics_path：定義接口后綴類型，默認(rèn)為/metrics
- 即我們輸入ip+端口后，瀏覽器會(huì)自動(dòng)追加/metrics后綴
[root@k8s-m1 ~]# vim prometheus.yml
···
scrape_configs:
- job_name: "Nginx"
metrics_path: '/status/format/prometheus'
static_configs:
- targets: ['172.23.0.243:8088']
···
[root@k8s-m1 ~]# docker restart prometheus
# 此時(shí)進(jìn)入prometheus管理頁面，則能查詢nginx的監(jiān)控項(xiàng)
8.各個(gè)監(jiān)控項(xiàng)的含義
Nginx-module-vts提供了多種監(jiān)控項(xiàng)，了解監(jiān)控項(xiàng)含義，有助于幫助自己生成需要的圖表

11.Docker部署nginx-module-vts模塊
由于yum安裝的nginx，默認(rèn)是沒有nginx-module-vts模塊的，需要下載對(duì)應(yīng)的nginx源碼，進(jìn)行重新編譯才行。
Docker 搭建 Consul集群（未完）
1.啟動(dòng)第一個(gè)consul服務(wù)：consul1
docker run --name consul1 -d -p 8500:8500 -p 8300:8300 -p 8301:8301 -p 8302:8302 -p 8600:8600 --restart=always consul:latest agent -server -bootstrap-expect 2 -ui -bind=0.0.0.0 -client=0.0.0.0
# 獲取 consul server1 的 ip 地址
docker inspect --format '{{ .NetworkSettings.IPAddress }}' consul1
172.17.0.2
# PS:
8500 http 端口，用于 http 接口和 web ui
8300 server rpc 端口，同一數(shù)據(jù)中心 consul server 之間通過該端口通信
8301 serf lan 端口，同一數(shù)據(jù)中心 consul client 通過該端口通信
8302 serf wan 端口，不同數(shù)據(jù)中心 consul server 通過該端口通信
8600 dns 端口，用于服務(wù)發(fā)現(xiàn)
-bbostrap-expect 2: 集群至少兩臺(tái)服務(wù)器，才能選舉集群leader
-ui：運(yùn)行 web 控制臺(tái)
-bind： 監(jiān)聽網(wǎng)口，0.0.0.0 表示所有網(wǎng)口，如果不指定默認(rèn)為127.0.0.1，則無法和容器通信
-client ： 限制某些網(wǎng)口可以訪問
2.啟動(dòng)第二個(gè)consul服務(wù)：consul2， 并加入consul1（使用join命令）
docker run -d --name consul2 -d -p 8501:8500 consul agent -server -ui -bind=0.0.0.0 -client=0.0.0.0 -join 172.17.0.2 docker run -d -p 8501:8500 --restart=always -v /XiLife/consul/data/server3:/consul/data -v /XiLife/consul/conf/server2:/consul/config -e CONSUL_BIND_INTERFACE='eth0' --privileged=true --name=consu2 consul agent -server -ui -node=consul2 -client='0.0.0.0' -datacenter=xdp_dc -data-dir /consul/data -config-dir /consul/config -join=172.17.0.2
3.啟動(dòng)第三個(gè)consul服務(wù)：consul3，并加入consul1
docker run --name consul3 -d -p 8502:8500 consul agent -server -ui -bind=0.0.0.0 -client=0.0.0.0 -join 172.17.0.2
4.查看運(yùn)行的容器（consul集群狀態(tài)）
[root@k8s-m1 consul]# docker exec -it consul1 consul members Node Address Status Type Build Protocol DC Segment 013a4a7e74d2 172.17.0.4:8301 alive server 1.10.0 2 dc1 <all> 3c118fa83d47 172.17.0.3:8301 alive server 1.10.0 2 dc1 <all> 4b5123c97c2b 172.17.0.5:8301 alive server 1.10.0 2 dc1 <all> a7d272ad157a 172.17.0.2:8301 alive server 1.10.0 2 dc1 <all>
5.服務(wù)注冊(cè)與剔除
- 接下來，我們要注冊(cè)服務(wù)到 Consul 中，可以通過其提供的 API 標(biāo)準(zhǔn)接口來添加
- 那么先注冊(cè)一個(gè)測(cè)試服務(wù)，該測(cè)試數(shù)據(jù)為本機(jī)
node-exporter服務(wù)信息，服務(wù)地址及端口為node-exporter默認(rèn)提供指標(biāo)數(shù)據(jù)的地址，執(zhí)行如下命令
# 注冊(cè)241的 node-exporter 服務(wù)信息
curl -X PUT -d '{"id": "node-exporter","name": "node-exporter-172.23.0.241","address": "172.23.0.241","port": 9100,"tags": ["prometheus"],"checks": [{"http": "http://172.23.0.241:9100/metrics", "interval": "5s"}]}' http://172.23.0.241:8500/v1/agent/service/register
# 注冊(cè)242的 node-exporter 服務(wù)信息
將上面所有IP地址改為242的即可，端口不變
如果要注銷掉某個(gè)服務(wù)，可以通過如下 API 命令操作，例如注銷上邊添加的 node-exporter 服務(wù)
curl -X PUT http://172.23.0.241:8500/v1/agent/service/deregister/node-exporter
