mycat连接mysql8.x并配置读写分离

首先需要将mycat\lib下的mysql-connector-java-xxx包删除,换成mysql-connector-java-8.0.19,然mycat能够支持mysql8.x

我用的mycat版本为mycat-server-1.6

schema.xml:

<?xml version="1.0"?>
<!DOCTYPE mycat:schema SYSTEM "schema.dtd">
<mycat:schema xmlns:mycat="http://io.mycat/">
 
	<schema name="TEST" checkSQLschema="true" sqlMaxLimit="100" dataNode="dn1">  <!--（一定要把checkSQLschema改成true）-->
		 
	</schema>

	<dataNode name="dn1" dataHost="host1" database="platform_admin" />
	

		<!-- 修改dbDriver  url  -->
	<dataHost name="host1" maxCon="1000" minCon="10" balance="1"
			  writeType="0" dbType="mysql" dbDriver="jdbc" switchType="1" slaveThreshold="100">
		<heartbeat>show slave status</heartbeat>
 
		<writeHost host="hostM1" url="jdbc:mysql://192.168.196.128:3307?useSSL=false&amp;serverTimezone=UTC" user="root"
				   password="root12">
			<!-- can have multi read hosts -->
			<readHost host="hostS2" url="jdbc:mysql://192.168.196.128:3308?useSSL=false&amp;serverTimezone=UTC" user="root" password="root12" /> 
		</writeHost>
		
	</dataHost>
	
</mycat:schema>

server.xml:

<!DOCTYPE mycat:server SYSTEM "server.dtd">
