1、准备 \n 基础环境：所有机器安装docker、完成时间校准\n---\n### 2、关闭防火墙\n所有机器运行\n```\nsystemctl stop firewalld\nsystemctl disable firewalld\n```\n---\n### 3、创建docker swarm集群\na、在prometheus主机上运行\n```\ndocker swarm init\n```\n控制台会打印加入集群口令，如：\n```\ndocker swarm join --token SWMTKN-1-69tr1fx5grwub5b7zi7qq4tq1crkddpurvf44kn3m57eb0w3xw-1xdagda6avqc512j88j9db70t 192.168.211.117:2377\n```\nTips:\n 如忘记口令，可通过以下命令查询\n```\ndocker swarm join-token worker\n```\nb、所有需要监控节点运行加入监控口令，如：\n```\ndocker swarm join --token SWMTKN-1-69tr1fx5grwub5b7zi7qq4tq1crkddpurvf44kn3m57eb0w3xw-1xdagda6avqc512j88j9db70t 192.168.211.117:2377\n```\n运行完后，可在manager节点查询节点信息：\n```\ndocker node ls\n```\nc、拉取exporter镜像\n所有节点都需要用到：cadvisor、node-exporter、dockerd-exporter\n ```\ndocker pull harbor.iibu.com/base/cadvisor:v0.31.0\ndocker pull harbor.iibu.com/base/node-exporter:v0.16.0\ndocker pull harbor.iibu.com/base/dockerd-exporter:v0.0.1\n ```\nd、修改配置\n./prometheus/config 如需要监控rabbitmq，配置其IP端口\n./docker-compose.yml 修改redis_exporter、mysqld_exporter 配置项\ne、主节点启动服务\n在docker-compose.yml所在目录运行\n```\nmkdir -p /monitor/grafana/data \nmkdir -p /monitor/prometheus/data \ndocker stack deploy -c docker-compose.yml monitor\n```\n服务启动后可查询启动状态：\n```\ndocker service ls\n```\n如：\n```\n[root@sup117211 ~]# docker service ls\nID NAME MODE REPLICAS IMAGE PORTS\nx5zqc37rgth3

container prune \n```\n---\n### 5、相关命令\na、更新docker-compose文件\n```\ndocker stack deploy -c docker-compose.yml _\n```\nb、更新config文件\n```\ndocker service rm _\ndocker config rm _\ndocker stack deploy -c docker-compose.yml _\n```\nc、集群节点down\n```\n# manager节点上删除该节点\ndocker node rm \n# manager节点查询加入口令\ndocker swarm join-token worker/manager\n# down节点上运行加入节点口令\ndocker swarm join --token :2377\n```\nd、集群节点添加label\n```\ndocker node update --label-add = \n```\ne、如何查看节点label\n```\ndocker node inspect \n```\nf、更新服务镜像版本\n```\ndocker service update --image _\n可以增加优化参数\n# 设定容器间更新时间间隔\n--update-delay 10s \\\n# 更新时同时并行更新数量，默认1\n--update-parallelism 2 \\\n# 任务容器更新失败时的模式 continue为继续使用\n--update-failure-action continue\n```\ng、回滚版本\n```\ndocker service update --rollback _\n可以增加优化参数\n--rollback-parallelism 2 \\\n--rollback-monitor 20s \\\n--rollback-max-failure-ratio .2
