如何使用 Docker 创建 Percona XtraDB 集群？

[英]How can I create Percona XtraDB cluster with Docker?

问题描述

  • I need to create Percona XtraDB cluster with "star" topology: with one master node (where I insert data) and two slave nodes (changes in master must be applied to slaves)我需要创建具有“星形”拓扑结构的 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）

  • Also I need to use Docker for this.此外，我需要为此使用 Docker。

What do I do:我该怎么办：

I got output to my console:我得到了我的控制台的输出：

If you need a multi-host environment, you can check https://www.percona.com/blog/2016/06/10/percona-xtradb-cluster-in-a-multi-host-docker-network/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/

If not, I've been working on some projects on this, feel free to check https://github.com/guriandoro/docker/tree/master/pxc , and in particularhttps://github.com/guriandoro/docker/tree/master/pxc/N-node-pxc .如果没有，我一直在做这方面的一些项目，请随时查看https://github.com/guriandoro/docker/tree/master/pxc ，特别是https://github.com/guriandoro/docker /tree/master/pxc/N-node-pxc 。

In the readme, you can find how to connect to them, and how to get the list of running nodes.在自述文件中，您可以找到如何连接到它们，以及如何获取正在运行的节点列表。 What do you mean by slave nodes, though?但是，从节点是什么意思？ Regular async replication?定期异步复制？ Or to add more nodes to the cluster?或者向集群添加更多节点？

Let me know if it helps, or if you have any feedback on it.如果它有帮助，或者您有任何反馈，请告诉我。 It's a work in progress, but you should be able to quickly have some nodes running in one host with minimal tweaking.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台主机上运行。

  • 3 nodes swarm workers(node1,node2,node3) 3 个节点群工作者（节点 1、节点 2、节点 3）
  • 1 node swarm manager(node4) 1 个节点群管理器（node4）

Ip's v4 nodes ip的v4节点

node1 - swarm worker - 192.168.1.108

Deploy stack部署堆栈

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

Go to web ui(unsecured)转到 web ui（不安全）

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

Wait until first node in cluster ok.等到集群中的第一个节点正常。

Then scale to 3 nodes然后扩展到 3 个节点

docker service scale pxc8_pxc=3 -d

Wait until cluster scale.等到集群规模。

Scale cluster to one node将集群扩展到一个节点

docker service scale pxc8_pxc=1 -d

Cluster with one node become non-Primary and not ready for operations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 |
+----------------------+---------+

After scale to one node, exec command on the last node with pxc(Most Advanced Node) make cluster Primary from non-Primary state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要状态变为主要

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

The node now operates as the starting node in a new Primary Component.该节点现在作为新主要组件中的起始节点运行。

SHOW GLOBAL STATUS LIKE 'wsrep_cluster_status';

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

Now we can scale our cluster to 3 or more nodes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

Fix cluster after crash all nodes在所有节点崩溃后修复集群

Edit file and set safe_to_bootstrap to 1 on node with latest data.编辑文件并在具有最新数据的节点上将 safe_to_bootstrap 设置为 1。

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

Edit file /var/lib/docker/volumes/pxc8_pxc_8_0/_data/gvwstate.dat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: 91aaf3ec-f33a-11ea-88f8-93c04e238f30 0
#vwend

And make changes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

Edit file /var/lib/docker/volumes/pxc8_pxc_8_0/_data/grastate.dat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

and stark cluster with one node again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

Reconnect pxc nodes to consul docker, if consul docker restarted如果 consul docker 重新启动，则将 pxc 节点重新连接到 consul docker

Go into container with pxc使用 pxc 进入容器

ps aux | grep consul

kill consul agent杀死领事代理

kill -9 13

and run process again in foregroud, with last command, added at the end of line并在前台再次运行进程，最后一个命令，添加到行尾

 /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;
