  • 我需要创建具有“星形”拓扑的 Percona XtraDB 集群：一个主节点（我在其中插入数据）和两个从节点（主节点的更改必须应用于从节点）

  • 我也需要为此使用 Docker。

我该怎么办：

我得到了控制台的输出：

问题是：

  • 如何访问集群中的数据库？
  • 如何将从节点添加到集群？
  • 如何获取集群节点列表？

如果需要多主机环境，可以查看https://www.percona.com/blog/2016/06/10/percona-xtradb-cluster-in-a-multi-host-docker-network/

如果没有，我一直在从事这方面的一些项目，请随时查看https://github.com/guriandoro/docker/tree/master/pxc，尤其是https://github.com/guriandoro/docker /tree/master/pxc/N-node-pxc。

在自述文件中，您可以找到如何连接它们，以及如何获取正在运行的节点列表。但是，从属节点是什么意思？定期异步复制？或者向集群添加更多节点？

让我知道它是否有帮助，或者您是否对此有任何反馈。这是一项正在进行的工作，但您应该能够通过最少的调整快速让一些节点在一个主机上运行。

依赖其他代码片段，让我们在 docker swarm 集群中使用 consul 创建 percona xtradb 集群 8.0

在 docker swarm 集群中创建 percona xtradb 集群。

要求

  • 3个节点swarm worker(node1,node2,node3)
  • 1 个节点群管理器（node4）

ip的v4节点

node1 - swarm worker - 192.168.1.108
node2 - swarm worker - 192.168.1.109
node3 - swarm worker - 192.168.1.110
node4 - swarm manager - 192.168.1.111

准备

为集群节点添加标签

docker node update --label-add pxc=true node1
docker node update --label-add pxc=true node2
docker node update --label-add pxc=true node3
docker node update --label-add consul=true node4

设置心跳周期

docker swarm update --dispatcher-heartbeat 20s

制作目录

mkdir -p /docker-compose/SWARM/pxc8/configs/consul

创建配置文件领事服务器

vim /docker-compose/SWARM/pxc8/configs/consul/config.json


{ 
  "advertise_addr" : "{{ GetInterfaceIP \"eth0\" }}",
  "bind_addr": "{{ GetInterfaceIP \"eth0\" }}",

创建 docker 撰写文件

vim /docker-compose/SWARM/pxc8/docker-compose.yml


version: '3.6'

services:
  
  consul:
    image: "devsadds/consul:1.8.3"
    hostname: consul
    volumes:
      - "/docker-compose/SWARM/pxc8/configs/consul:/consul/config"

    command: "consul agent -config-file /consul/config/config.json"
    deploy:
      mode: replicated
      replicas: 1
      restart_policy:
        condition: on-failure
        delay: 15s
        max_attempts: 13

        max_failure_ratio: 0.3
      placement:
        constraints: [ node.labels.consul  == true ]

  pxc:

        max_attempts: 23
        window: 180s
      update_config:

        max_failure_ratio: 0.3
      placement:

volumes:
  pxc_8_0:

  pxc8-net:

部署堆栈

cd /docker-compose/SWARM/pxc8
docker stack deploy -c docker-compose.yml pxc8 --resolve-image always --prune --with-registry-auth

转到 web ui（不安全）

http://192.168.1.111:8500/ui/dc1/services/pxc8/instances

等到集群中的第一个节点正常。

然后扩展到 3 个节点

docker service scale pxc8_pxc=3 -d

等到集群规模。

将集群扩展到一个节点

docker service scale pxc8_pxc=1 -d

具有一个节点的集群变为非主节点且未准备好进行操作

SHOW GLOBAL STATUS LIKE 'wsrep_cluster_status';

+----------------------+---------+
| Variable_name        | Value   |
+----------------------+---------+
| wsrep_cluster_status | non-Primary |
+----------------------+---------+

扩展到一个节点后，使用 pxc（最高级节点）在最后一个节点上执行命令，使集群从非主状态变为主节点

SET GLOBAL wsrep_provider_options='pc.bootstrap=YES';

该节点现在作为新主组件中的起始节点运行。

SHOW GLOBAL STATUS LIKE 'wsrep_cluster_status';

+----------------------+---------+
| Variable_name        | Value   |
+----------------------+---------+
| wsrep_cluster_status | Primary |
+----------------------+---------+

现在我们可以将集群扩展到 3 个或更多节点

docker service scale pxc8_pxc=3 -d

在所有节点崩溃后修复集群

编辑文件并将具有最新数据的节点上的 safe_to_bootstrap 设置为 1。

cd /docker-compose/SWARM/pxc8
docker stack rm pxc8

编辑文件 /var/lib/docker/volumes/pxc8_pxc_8_0/_data/gvwstate.dat

nano /var/lib/docker/volumes/pxc8_pxc_8_0/_data/gvwstate.dat 

my_uuid: 505b00f5-f33a-11ea-9ee4-abd76ca92272
#vwbeg
view_id: 3 505b00f5-f33a-11ea-9ee4-abd76ca92272 52
bootstrap: 0
member: 505b00f5-f33a-11ea-9ee4-abd76ca92272 0
member: 88f6da78-f1fc-11ea-81cc-e386dd9bf4d3 0
member: 91aaf3ec-f33a-11ea-88f8-93c04e238f30 0
#vwend

并做出改变

my_uuid: 505b00f5-f33a-11ea-9ee4-abd76ca92272
#vwbeg
view_id: 3 505b00f5-f33a-11ea-9ee4-abd76ca92272 52
bootstrap: 0
member: 505b00f5-f33a-11ea-9ee4-abd76ca92272 0
#vwend

编辑文件 /var/lib/docker/volumes/pxc8_pxc_8_0/_data/grastate.dat

nano /var/lib/docker/volumes/pxc8_pxc_8_0/_data/grastate.dat

safe_to_bootstrap 1

并再次与一个节点形成鲜明的集群

cd /docker-compose/SWARM/pxc8
docker stack deploy -c docker-compose.yml pxc8 --resolve-image always --prune --with-registry-auth

如果 consul docker 重新启动，则将 pxc 节点重新连接到 consul docker

使用 pxc 进入容器

ps aux | grep consul

杀死领事代理人

kill -9 13

并在前台再次运行进程，最后一个命令，添加在行尾

 /bin/consul agent -retry-join consul -client 0.0.0.0 -bind 10.22.0.17 -node -99f341353c95 -data-dir /tmp -config-file /tmp/pxc.json &amp;
