安装mycat


下载解压

wget http://dl.mycat.io/1.6.5/Mycat-server-1.6.5-release-20180122220033-linux.tar.gz
tar -zxvf Mycat-server-1.6.5-release-20180122220033-linux.tar.gz -C /usr/local/
cd /usr/local/mycat/conf

根据实际情况修改schema.xml,server.xml
例如:
schema.xml:

<?xml version="1.0"?>
<!DOCTYPE mycat:schema SYSTEM "schema.dtd">
<mycat:schema xmlns:mycat="http://io.mycat/">
     <!-- phapp 是mycat的逻辑库名称,链接需要用的 -->
    <schema name="xx_app" checkSQLschema="false" sqlMaxLimit="100" dataNode="dn1"></schema>
    <schema name="xx_data" checkSQLschema="false" sqlMaxLimit="100" dataNode="dn2"></schema>
    <schema name="xx_dubbo_monitor" checkSQLschema="false" sqlMaxLimit="100" dataNode="dn3"></schema>
    <schema name="xx_log" checkSQLschema="false" sqlMaxLimit="100" dataNode="dn4"></schema>
    <schema name="xx_mis" checkSQLschema="false" sqlMaxLimit="100" dataNode="dn5"></schema>
    <schema name="xx_task" checkSQLschema="false" sqlMaxLimit="100" dataNode="dn6"></schema>
        <!-- database 是MySQL数据库的库名 -->

    <dataNode name="dn1" dataHost="192.168.75.94" database="xx_app" />
    <dataNode name="dn2" dataHost="192.168.75.94" database="xx_data" />
    <dataNode name="dn3" dataHost="192.168.75.94" database="xx_dubbo_monitor" />
    <dataNode name="dn4" dataHost="192.168.75.94" database="xx_log" />
    <dataNode name="dn5" dataHost="192.168.75.94" database="xx_mis" />

    <dataNode name="dn6" dataHost="192.168.75.94" database="xx_task" />
    <!--
    dataNode节点中各属性说明:
    name:指定逻辑数据节点名称;
    dataHost:指定逻辑数据节点物理主机节点名称;
    database:指定物理主机节点上。如果一个节点上有多个库,可使用表达式db$0-99,     表示指定0-99这100个数据库;

    dataHost 节点中各属性说明:
        name:物理主机节点名称;
        maxCon:指定物理主机服务最大支持1000个连接;
        minCon:指定物理主机服务最小保持10个连接;
        writeType:指定写入类型;
            0,只在writeHost节点写入;
            1,在所有节点都写入。慎重开启,多节点写入顺序为默认写入根据配置顺序,第一个挂掉切换另一个;
        dbType:指定数据库类型;
        dbDriver:指定数据库驱动;
        balance:指定物理主机服务的负载模式。
            0,不开启读写分离机制;
            1,全部的readHost与stand by writeHost参与select语句的负载均衡,简单的说,当双主双从模式(M1->S1,M2->S2,并且M1与 M2互为主备),正常情况下,M2,S1,S2都参与select语句的负载均衡;
            2,所有的readHost与writeHost都参与select语句的负载均衡,也就是说,当系统的写操作压力不大的情况下,所有主机都可以承担负载均衡;
-->
    <dataHost name="192.168.75.94" maxCon="1000" minCon="10" balance="3" writeType="0" dbType="mysql" dbDriver="native" switchType="1"  slaveThreshold="100">
