rule.xml

Java代码

<?xml version="1.0" encoding="gbk"?>

<!DOCTYPE amoeba:rule SYSTEM "rule.dtd">

<amoeba:rule xmlns:amoeba="http://amoeba.meidusa.com/">

<tableRule name="message" schema="test" defaultPools="server1">

</tableRule>

</amoeba:rule>

<?xml version="1.0" encoding="gbk"?>
<!DOCTYPE amoeba:rule SYSTEM "rule.dtd">
<amoeba:rule xmlns:amoeba="http://amoeba.meidusa.com/">
<tableRule name="message" schema="test" defaultPools="server1">
</tableRule>
</amoeba:rule>

不需要 数据库分片时，不用配置。 但是不能没有 tableRule 元素， 否则报错。 随便写个空规则就行了。

3. 测试读写分离

a. 在 Master ， Slave1 ， Slave2 中分别查看 日志文件： mysql.log

Shell代码

tail -f ./log/mysql.log

tail -f ./log/mysql.log

b. 启动 Amoeba， 使用 Mysql GUI Tools 连接 Amoeba





执行以上几个命令。 查看日志内容。

从日志中可以看出。
在 Master mysql.log 中，只执行了 insert into 命令。
在 Slave1 中，只是复制了 insert into 命令， 是主从复制的结果
在 Slave2 中， 复制了 insert into 命令，同时还执行了 select 命令。

说明，主从分离已经成功。
