magento数据库日志的清除及优化

magento数据库日志的清除及优化

magento本身会记录很多日志,
这些日志长年累积会占用非常大的空间。
下面是一些日志表

'dataflow_batch_export',
'dataflow_batch_import',
'log_customer',
'log_quote',
'log_summary',
'log_summary_type',
'log_url',
'log_url_info',
'log_visitor',
'log_visitor_info',
'log_visitor_online',
'report_event',
'report_compared_product_index',
'report_viewed_product_index',

上面这些日志表基本上会占用一半的数据空间

而很多时间这些表数据根本不会用到,
所以定时清理很有必要

清除方法

一:后台清除

1:登入后进入 System > Configuration.
2:左侧菜单 Advanced 下点击 System.
3:在”Log Cleaning”下, 改变”Enable Log Cleaning” 为 YES 并且配置Save Log 为15 days:

二:可以通过Magento自身的cron定时清理日志。
三:执行SQL清理,

truncate dataflow_batch_export;
truncate dataflow_batch_import;
truncate log_customer;
truncate log_quote;
truncate log_summary;
truncate log_summary_type;
truncate log_url;
truncate log_url_info;
truncate log_visitor;
truncate log_visitor_info;
truncate log_visitor_online;
truncate report_viewed_product_index;
truncate report_compared_product_index;
truncate report_event;
set foreign_key_checks = 0;
truncate index_process_event;
truncate index_event;
set foreign_key_checks = 1;

数据库清理数据有风险,请注意备份好数据库

四:代码清除:
