Docker 部署 Prometheus的安裝詳細教程
Docker 部署 Prometheus 說明：
監(jiān)控端安裝：Prometheus Server(普羅米修斯監(jiān)控主服務器 )Node Exporter (收集Host硬件和操作系統(tǒng)信息)cAdvisor (負責收集Host上運行的容器信息)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 (負責收集Host上運行的容器信息)
1.安裝Node Exporter 所有服務器安裝 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 exporteree30add8d207 prom/node-exporter '/bin/node_exporter …' About a minute ago Up About a minute condescending_shirley2.安裝cAdvisor 所有服務器安裝 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

可以進入容器查看：[root@agent ~]# sudo docker exec -it 容器id /bin/sh3.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地址# my global configglobal: 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 configurationalerting: 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，在grafana識別不到！
# my global configlobal: 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 configurationalerting: 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Prometheus容器啟動成功后訪問# PS：服務器需開啟eth0的外網(wǎng)端口，才可用瀏覽器訪問 9090 0.0.0.0106.15.0.11:90904.創(chuàng)建運行Grafana 監(jiān)控服務器安裝 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：服務器需開啟eth0的外網(wǎng)端口，才可用瀏覽器訪問：3000 0.0.0.0Grafana啟動后，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器
然后為添加好的數(shù)據(jù)源做圖形顯示
這時候可以自己選擇編譯對應的模板，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 io_namespace_http_requests_total 我們可以：
查詢應用的請求總量sum(io_namespace_http_requests_total)查詢每秒Http請求量sum(rate(io_wise2c_gateway_requests_total[5m]))查詢當前應用請求量Top N的URItopk(10, sum(io_namespace_http_requests_total) by (path))
配置Prometheus監(jiān)控Nginx
1、需給Nginx安裝兩個模塊，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，基于原來安裝選項的基礎(chǔ)上，增加以上兩個模塊選項，進行編譯安裝，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目錄再移動到編譯安裝后的nignx目錄內(nèi)，最后啟動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 repobaseurl=http://nginx.org/packages/centos/7/$basearch/gpgcheck=1enabled=1gpgkey=https://nginx.org/keys/nginx_signing.keymodule_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.confuser www;
5）啟動服務
1.方法一：直接啟動如果有報錯==》重大錯誤，80端口有占用==》查看占用端口的服務HTTPD，停掉，在重啟nginx[root@web01 ~]# systemctl start nginx2.方法二：[root@web01 ~]# nginx
1.查看當前Nginx安裝選項
[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
# 停止nginx服務[root@k8s-n1 packages]# nginx -s stop# 備份原nginx啟動文件[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
編譯安裝時可能會出現(xiàn) `make: *** 沒有規(guī)則可以創(chuàng)建“default”需要的目標“build”。 停止`的報錯，是因為缺少依賴導致# 管他三七21，裝一波兒在進行編譯，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

由于yum安裝的nginx，默認是沒有nginx-module-vts模塊的，需要下載對應的nginx源碼，進行重新編譯才行。
Docker 搭建 Consul集群（未完）1.啟動第一個consul服務：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 }}’ consul1172.17.0.2# 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，用于服務發(fā)現(xiàn) -bbostrap-expect 2: 集群至少兩臺服務器，才能選舉集群leader -ui：運行 web 控制臺 -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.啟動第二個consul服務：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 172.17.0.2docker 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.啟動第三個consul服務：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.查看運行的容器（consul集群狀態(tài)）
[root@k8s-m1 consul]# docker exec -it consul1 consul membersNode Address Status Type Build Protocol DC Segment013a4a7e74d2 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.服務注冊與剔除
接下來，我們要注冊服務到 Consul 中，可以通過其提供的 API 標準接口來添加 那么先注冊一個測試服務，該測試數(shù)據(jù)為本機 node-exporter 服務信息，服務地址及端口為 node-exporter 默認提供指標數(shù)據(jù)的地址，執(zhí)行如下命令# 注冊241的 node-exporter 服務信息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242的 node-exporter 服務信息將上面所有IP地址改為242的即可，端口不變
如果要注銷掉某個服務，可以通過如下 API 命令操作，例如注銷上邊添加的 node-exporter 服務
curl -X PUT http://172.23.0.241:8500/v1/agent/service/deregister/node-exporter
