如何使用Docker创建Percona XtraDB集群？

时间：2016-12-06 18:14:14

标签： docker percona xtradb

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

  • 此外，我还需要使用Docker。

我该怎么做：

我输出到我的控制台：

准则是：

  • 如何访问群集中的数据库？
  • 如何将群集节点添加到群集？
  • 如何获取群集节点列表？

2 个答案:

答案 0 :(得分：1)

如果您需要多主机环境，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，我一直就此开展一些项目，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。

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，从节点是什么意思？定期异步复制？或者向集群添加更多节点？

如果有帮助，或者您对此有任何反馈，请告诉我。这是一项正在进行中的工作，但您应该能够快速地在一台主机上运行一些节点，而且调整很少。

取决于其他snippets，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个节点组成工作组（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

PREPARE

向群体节点添加标签

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

创建目录

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\" }}",

部署堆栈

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

转到网络用户界面（不安全）

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

等待直到群集ok中的第一个节点。

然后扩展到3个节点

docker service scale pxc8_pxc=3 -d

等到集群规模。

将群集扩展到一个节点

docker service scale pxc8_pxc=1 -d

具有一个节点的集群成为非主集群并且无法进行操作

SHOW GLOBAL STATUS LIKE 'wsrep_cluster_status';

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

扩展到一个节点后，在最后一个具有pxc（最高级节点）的节点上执行命令，使群集从非主状态变为主状态

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

该节点现在充当新主组件中的起始节点。

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

修复所有节点崩溃后的群集

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: 91aaf3ec-f33a-11ea-88f8-93c04e238f30 0
#vwend

并进行更改

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

并再次形成一个节点的纯集群

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

如果领事docker重新启动，则将pxc节点重新连接到领事docker

使用pxc进入容器

ps aux | grep consul

杀死领事代理

kill -9 13

并再次在前例中运行过程，最后一行添加到行尾

 /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;
