使用Rancher配置mycat读写分离

基础环境

接上篇，主从已经做好，看下现有的数据库和服务发现

配置Mycat配置文件

直接配置映射：

只做个简单的读写分离，所以只需要修改schema.xml和server.xml两个配置文件，所需数据库账号已提前授权

schema.xml

<?xml version="1.0"?>
<!DOCTYPE mycat:schema SYSTEM "schema.dtd">
<mycat:schema xmlns:mycat="http://io.mycat/">


        <schema name="ceshi1" checkSQLschema="false" sqlMaxLimit="100" dataNode="dn1"></schema>
        <schema name="ceshi2" checkSQLschema="false" sqlMaxLimit="100" dataNode="dn2"></schema>


        <dataNode name="dn1" dataHost="localhost1" database="ceshi1" />
        <dataNode name="dn2" dataHost="localhost1" database="ceshi2" />

        <dataHost name="localhost1" maxCon="9000" minCon="10" balance="1"
                writeType="0" dbType="mysql" dbDriver="native" switchType="2"  slaveThreshold="100">
                <heartbeat>show slave status</heartbeat>
                <writeHost host="hostM1" url="10.104.23.216:3306" user="oel_mycat" password="oel_xxxxx" >
                        <readHost host="hostS1" url="10.106.89.11:3306" user="oel_mycat" password="oel_xxxxx" />
                        <readHost host="hostS2" url="10.111.177.163:3306" user="oel_mycat" password="oel_xxxxx" />
                </writeHost>
        </dataHost>

</mycat:schema>
