我正在使用Magento ver。 1.9.1.0
我面临的问题是每当我从magento admin重新索引数据时，它会显示错误，如
There has been an error processing your request
SQLSTATE[HY000]: General error: 2006 MySQL server has gone away, query was: SELECT `core_flag`.* FROM `core_flag` WHERE (`core_flag`.`flag_code`='synchronize')

由于这个原因，网站加载速度很慢。这是什么原因以及如何解决这个问题？
答案 0 :(得分：0)
我遇到了同样的问题，所以我根据服务器容量将此配置更改为。
innodb_lock_wait_timeout
key_buffer
max_allowed_packet
thread_stack
thread_cache_size
innodb_buffer_pool_size
