_默认情况下MySQL的复制是异步的，Master上所有的更新操作写入Binlog之后并不确保所有的更新都被复制到Slave之上。异步操作虽然效率高，但是在Master/Slave出现问题的时候，存在很高数据不同步的风险，甚至可能丢失数据。_ _MySQL5.5引入半同步复制功能的目的是为了保证在master出问题的时候，至少有一台Slave的数据是完整的。在超时的情况下也可以临时转入异步复制，保障业务的正常使用，直到一台salve追赶上之后，继续切换到半同步模式。_ ### 具体配置 _mysql5.5半同步插件是由谷歌提供，具体位置/usr/lib/mysql/plugin/下，一个是master用的semisync_master.so，一个是slave用的semisync_slave.so，具体配置如下_ master: (1).安装插件 ``` mysql> INSTALL PLUGIN rpl_semi_sync_master SONAME 'semisync_master.so'; Query OK, 0 rows affected (0.39 sec) mysql> SET GLOBAL rpl_semi_sync_master_enabled = 1; Query OK, 0...
