运行Docker 的主机可以主动初始化一个 Swarm 集群或者加入一个已存在的 Swarm 集群,这样这个运行 Docker 的主机就成为一个 Swarm 集群的节点 (node) 。 节点分为管理 (manager) 节点和工作 (worker) 节点。 管理节点用于 Swarm 集群的管理,docker swarm 命令基本只能在管理节点执行(节点退出集群命令 docker swarm ...
1、运行yum remove docker删除安装件 2、重新安装 yum install https://get.docker.com/rpm/1.7.1/centos-6/RPMS/x86_64/docker-engine-1.7.1-1.el6.x86_64.rpm 3、启动服务就可以了service docker start 启动服务后输入 service docker status 查看docker 的运行 发现报错:“ docker dead but pid file ex...
1. Check if Docker is installed Run the following command to check if Docker is installed: docker --version 1. If it returns a version, Docker is installed but the service might be misconfigured. If it outputscommand not found, Docker is not installed. 2. Install Docker If Docker is not...

管理节点用于 Swarm 集群的管理,docker swarm 命令基本只能在管理节点执行(节点退出集群命令 docker swarm leave 可以在工作节点执行)。一个 Swarm 集群可以有多个管理节点,但只有一个管理节点可以成为 leader,leader 通过 raft 协议实现。 工作节点是任务执行节点,管理节点将服务 (service) ...
