Introduction

Percona XtraDB Cluster 镜像，Galera 同步多主 MySQL 高可用集群，企业级 MySQL HA 与自动故障转移方案。

Details

percona/percona-xtradb-cluster 运行 Percona XtraDB Cluster（PXC），基于 Galera 提供同步多主 MySQL 复制与高可用。定位为 MySQL HA 集群节点，需 3+ 节点 quorum；金融/电商核心数据库 HA、零数据丢失 MySQL 集群或替代主从+MHA 方案。

快速启动

docker run -d --name pxc \
  -p 3306:3306 \
  -e CLUSTER_NAME=pxc-cluster \
  -e MYSQL_ROOT_PASSWORD=changeme \
  docker.io/percona/percona-xtradb-cluster:8.0

推荐实践

docker run -d --name pxc \
  --restart unless-stopped \
  -p 3306:3306 \
  -e CLUSTER_NAME=pxc-cluster \
  -e MYSQL_ROOT_PASSWORD=changeme \
  -e WSREP_CLUSTER_ADDRESS=gcomm://pxc-1,pxc-2,pxc-3 \
  -v /data/pxc:/var/lib/mysql \
  docker.io/percona/percona-xtradb-cluster:8.0.35

核心参数说明

  • WSREP_CLUSTER_ADDRESS — 集群节点列表
  • MYSQL_ROOT_PASSWORD — root 密码（高敏）
  • quorum — 建议 3 节点奇数
  • -v .../mysql:... — 数据持久化
