3.mysql读写分离配置
<resources> <db> <table_prefix><![CDATA[]]></table_prefix> </db> <default_setup> <connection> <host><![CDATA[localhost]]></host> <username><![CDATA[root]]></username> <password><![CDATA[]]></password> <dbname><![CDATA[mg_wailian]]></dbname> <initStatements><![CDATA[SET NAMES utf8]]></initStatements> <model><![CDATA[mysql4]]></model> <type><![CDATA[pdo_mysql]]></type> <pdoType><![CDATA[]]></pdoType> <active>1</active> </connection> </default_setup> <default_read> <connection> <host><![CDATA[localhost]]></host> <username><![CDATA[root]]></username> <password><![CDATA[]]></password> <dbname><![CDATA[mg_wailian]]></dbname> <initStatements><![CDATA[SET NAMES utf8]]></initStatements> <model><![CDATA[mysql4]]></model> <type><![CDATA[pdo_mysql]]></type> <pdoType><![CDATA[]]></pdoType> <active>1</active> </connection> </default_read> </resources> |
3.分离读写数据库，然后主从同步，是一个很好的选择。
