建立5節點的PXC叢集
注意，每個MySQL容器建立之後，因為要執行PXC的初始化和加入叢集等工作，耐心等待1分鐘左右再用客戶端連線MySQL。另外，必須第1個MySQL節點啟動成功，用MySQL客戶端能連線上之後，再去建立其他MySQL節點。
#建立第1個MySQL節點 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 #建立第2個MySQL節點 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 #建立第3個MySQL節點 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 #建立第4個MySQL節點 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 #建立第5個MySQL節點 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 -
