你就不要折腾这个了 直接使用集群
我直接给你资料好了 以前给客户部署的 任意节点都可以读写
有些可能有些过时了

MYSQL 数据库 DMM 架构设计
使用 MariaDB 作为数据库引擎 表使用 InnoDB storage engine.
可能有部分功能性缺陷 可以参考
https://mariadb.com/kb/en/mariadb/documentation/replication/galera/mariadb-galera-cluster-known-limitations/因为按你们的需求 只能使用多主的架构
这样可以降低数据库并发的压力 提高写入效率
如果性能下降 增加数据库节点即可
所有数据全部都会自动同步 不需要人工干预
使用方式: 当前 2 节点可用
准备一个域名
将域名 DNS 改为
www.dnspod.com 国际站 非国内站
增加解析记录 (假如
test.com 是你的域名)
CNAME 记录 一条
sqlcloud.test.com CNAME 记录
node.test.comA 记录 (IPv4 协议)
node A 记录 default 173.255.199.172
node A 记录 default 198.58.114.176
AAAA 记录 (IPv6 协议)
node AAAA default 2600:3c00::f03c:91ff:fe89:e46
node AAAA default 2600:3c00::f03c:91ff:fe89:ea9
TTL 设置为 300 或 600
default 是 GEO 分流 可以设置一个大洲或者一个国家每服务器
使用 DNSPOD 国际版 是因为这个支持多记录轮询模式
例如如果有 1000 个 DNS 请求 DNSPOD 会使用 RR 模式 轮流返回可用 IP
就是每个 IP 分配 500 个请求,这样实现多数据库服务器写入 提高性能
然后链接语句
使用
sqlcloud.test.com:3306 会随机分配 IP
root
1111111111
数据库名称
读写数据 都会自动同步在多个节点中
这个平台可测试可以商用
插入 10 万条数据 无脑裂问题
如果有出现 可以增加仲载节点解决
PS. 已修正 MYSQL 用户表,MYISAM 无法自动同步问题
