Then we edit the configuration file /etc/mysql/my.cnf and add the following lines - be sure to use different server ids for all hosts: server_id = 1 log_bin = /var/log/mysql/mysql-bin.log log_bin_index = /var/log/mysql/mysql-bin.log.index relay_log = /var/log/mysql/mysql-rela...
MMM(Master-Master replication manager for Mysql)是一套灵活的脚本程序,用来监控和故障切换,管理mysql Master-Master复制的配置 (同一时间只有一个节点是可写的)。附带的工具套件可以实现多个slaves的read负载均衡,因此你可以使用这个工具移除一组服务器中复制延迟较高的服务器的虚拟IP,它还可以备份数据,两节点之间再...
MySQL Master-Master Replication Manager 前置作业 MySQL Master-Master 的架构, 需要准备的资讯如下: •机器3台以上(最少3台): 2台做MySQL Server, 1台做Monitor(监控机器可与Apache 等共用即可). •IP 5个以上(2N+1): MySQL Server 有几台, 需要的IP 是MySQL Server 台数x 2, 再加上Monitor 要一个...

一、为什么要做Mysql的主从复制(读写分离)? 通俗来讲,如果对数据库的读和写都在同一个数据库服务器中操作,业务系统性能会降低。 为了提升业务系统性能,优化用户体验,可以通过做主从复制(读写分离)来减轻主数据库的负载。 而且如果主数据库宕机,可快速将业务系统切换到从数据库上,可避免数据丢失。
为了解决这个问题,可以通过搭建Dual Master环境来处理,就是两个MySQL Server互相将对方作为自己的Master,自己作为对方的Slave来进行复制。这样,任何一方所做的变更,都会通过复制应用到另外一方的数据库中 这样搭建复制环境之后,会不会造成两台MySQL之间的循环复制?
