GitHub-Mycat板块最佳实践-亲试ok

 
 
  1. 逻辑库配置：
 
1.1  配置server.xml
 
创建一个mycat逻辑库：imooc_db
system 参数是所有的mycat参数配置，比如 添加解析器：defaultSqlParser，其他类推
user 是用户参数。
   <user name="app_imooc" defaultAccount="true">
   <property name="password">123456</property>
   <property name="schemas">imooc_db</property>
  </user>
 
注意此处：
app_imooc 用户名
123456 用户密码
imooc_db 逻辑库
 
 
1.2   编辑schema.xml
修改dataHost和schema对应的连接信息
 
 
dataNode是逻辑库对应的分片，如果配置多个分片需要多个dataNode即可。
 
dataHost是实际的物理库配置地址。
下面的writeHost、readHost代表该分片是否配置多写，主从，读写分离等高级特性。
 

 

<schema name="imooc_db" checkSQLschema="false" sqlMaxLimit="100" dataNode="user" />
    <table name="order_master" primaryKey="order_id" dataNode="ordb_dn"/>
</schema>
 

 

<dataNode name="ord_dn" dataHost="192.168.124.158" database="order_db" />
<dataNode name="prod_dn" dataHost="192.168.124.159" database="product_db" />
<dataNode name="cust_dn" dataHost="192.168.124.160" database="custer_db" />
 

 

<dataHost name="192.168.124.159" maxCon="1000" minCon="10" balance="0"
   writeType="0" dbType="mysql" dbDriver="native">
   <heartbeat>select 1</heartbeat>
   <!-- can have multi write hosts -->
  <writeHost host="192.168.124.159" url="192.168.124.159:3306" user="root" password="123456" />
   #<writeHost host="hostM2" url="192.168.0.3:3306" user="root" password="root" />
</dataHost>
 

 

<dataHost name="192.168.124.160" maxCon="1000" minCon="10" balance="0"
   writeType="0" dbType="mysql" dbDriver="native">
   <heartbeat>select 1</heartbeat>
   <!-- can have multi write hosts -->
    <writeHost host=192.168.124.160" url="192.168.124.160:3306" user="root" password="123456" />
</dataHost>
 
测试连接：
[root@m-157 ~]# mysql -uapp_imooc -p123456 -h127.0.0.1 -P8066

对MyCAT的用户密码做加密
[root@m-157 lib]# java -cp Mycat-server-1.6.5-release.jar io.mycat.util.DecryptUtil 0:zpp_imooc:123456
PdvreoR7rtZepoGBQem6nTggPY8cmx8lts7itp7/bOiTj+s1OTSk5kpyo/FZl8z/jwqQT5qKaEsSAXM/OXwX7w==
 
再次修改server.xml文件
添加如下 ：
   <user name="app_imooc" defaultAccount="true">
   <property name="password">PdvreoR7rtZepoGBQem6nTggPY8cmx8lts7itp7/bOiTj+s1OTSk5kpyo/FZl8z/jwqQT5qKaEsSAXM/OXwX7w==</property>
   <property name="schemas">imooc_db</property>
  </user>
 
配置文件如下：
[root@m-157 conf]# cat schema.xml
<?xml version="1.0"?>
