Flush need to be considered to maximize performance and system value. In the software domain, MySQL Server is a commonly used Relational Database Management System (RDBMS).This whitepaper clarifies how today's substantial business advantage. The paper focuses on Percona Server – a free, fully compatible, open source MySQL Server enhancement. Because Percona Server is optimized for the I/O subsystem, it was selected

keepalived 作为故障转移，提高系统的可用性。但是一般的 mysql 高可用为了实现 mysql 数据的一致性，一般都是采用单点写入，本方案采用 keepalived 中的 sorry_server 来实现写入数据库为单点的需求。本方案实现的功能是当网络有问题、 mysql 有问题、服务器宕机、keepalived 服务停止后,服务器能自动跳转到备用机， 当主服务器服务启动起来后会自动切换回来。 VIP 分别进行设置，为读写分离做准备。  扩展不是很方便。  可以在后面添加多个从服务器，并做到负载均衡。 缺点：  在启动或者恢复后会立即替换掉定义的 sorry_server，因此如果要实现指 定条件替换或者不替换需要通过其他方式实现，比如：临时更改 mysql 的端口等。  切换需要 1s 左右的时间。 2.4 方案实战 2.4.1 适用场景 zhangxy@test.com } notification_email_from jiankong@test.com smtp_server mail.test.com smtp_connect_timeout 30 router_id LVS1 } vrrp_sync_group test

使用 Docker 建立 Mysql 集群 软件环境介绍 操作系统：Ubuntu server 64bit 14.04.1 Docker 版本 1.6.2 数据库：Mariadb 10.10 （Mariadb 是 MySQL 之父在 MySQL 被 Oracle 收购之后 创建的分支，性能上优于 MySQL 开源版本） 第一步 安装 Docker 对于 Ubuntu，建议直接联网安装 Docker mdb1 /bin/bash 进入主数据库容器内之后， vi /etc/mysql/my.cnf 把“server-id = 1”行的注释去掉即可，保存，退出容器，然后 docker restart mdb1 同样的，把从数据库的 my.cnf 修改“server-id = 2”,需要是比主 server-id 大的数字，mdb2 同样需要重启。 3.4 使用客户端连接上主数据库，这里我使用的是 mysql
