docker 部署 笔记
Docker虚拟机常用命令
- 先更新软件包
yum -y update
- 安装Docker虚拟机
yum install -y docker
- 运行、重启、关闭Docker虚拟机
service docker start
service docker start
service docker stop
- 搜索镜像
docker search 镜像名称
- 下载镜像
docker pull 镜像名称
- 查看镜像
docker images
- 删除镜像
docker rmi 镜像名称
- 运行容器
docker run 启动参数 镜像名称
- 查看容器列表
docker ps -a
- 停止、挂起、恢复容器
docker stop 容器ID
docker pause 容器ID
docker unpase 容器ID
- 查看容器信息
docker inspect 容器ID
- 删除容器
docker rm 容器ID
- 数据卷管理
docker volume create 数据卷名称 #创建数据卷
docker volume rm 数据卷名称 #删除数据卷
docker volume inspect 数据卷名称 #查看数据卷
- 网络管理
docker network ls 查看网络信息
docker network create --subnet=网段 网络名称
docker network rm 网络名称
- 避免VM虚拟机挂起恢复之后，Docker虚拟机断网
vi /etc/sysctl.conf
文件中添加
net.ipv4.ip_forward=1这个配置#重启网络服务
systemctl restart network
安装PXC集群，负载均衡，双机热备
- 安装PXC镜像
docker pull percona/percona-xtradb-cluster
- 为PXC镜像改名
docker tag percona/percona-xtradb-cluster pxc
- 创建net1网段
docker network create --subnet=172.18.0.0/16 net1
- 创建5个数据卷
docker volume create --name v1
docker volume create --name v2
docker volume create --name v3
docker volume create --name v4
docker volume create --name v5
- 创建备份数据卷（用于热备份数据）
docker volume create --name backup
- 创建5节点的PXC集群
注意，每个MySQL容器创建之后，因为要执行PXC的初始化和加入集群等工作，耐心等待1分钟左右再用客户端连接MySQL。另外，必须第1个MySQL节点启动成功，用MySQL客户端能连接上之后，再去创建其他MySQL节点。
#创建第1个MySQL节点
docker run -d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -v v1:/var/lib/mysql -v backup:/data --privileged --name=node1 --net=net1 --ip 172.18.0.2 pxc
#创建第2个MySQL节点
docker run -d -p 3307:3306 -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -e CLUSTER_JOIN=node1 -v v2:/var/lib/mysql -v backup:/data --privileged --name=node2 --net=net1 --ip 172.18.0.3 pxc
#创建第3个MySQL节点
docker run -d -p 3308:3306 -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -e CLUSTER_JOIN=node1 -v v3:/var/lib/mysql --privileged --name=node3 --net=net1 --ip 172.18.0.4 pxc
#创建第4个MySQL节点
docker run -d -p 3309:3306 -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -e CLUSTER_JOIN=node1 -v v4:/var/lib/mysql --privileged --name=node4 --net=net1 --ip 172.18.0.5 pxc
#创建第5个MySQL节点
docker run -d -p 3310:3306 -e MYSQL_ROOT_PASSWORD=abc123456 -e CLUSTER_NAME=PXC -e XTRABACKUP_PASSWORD=abc123456 -e CLUSTER_JOIN=node1 -v v5:/var/lib/mysql -v backup:/data --privileged --name=node5 --net=net1 --ip 172.18.0.6 pxc
