max_allowed_pa​​cket和文件上傳問題

Question

我不得不從備份恢復我的文字新聞網站。在備份之前，我能夠從這個頁面上傳得很好。從備份恢復後，當我嘗試上載文件時，現在出現以下錯誤。我上傳的文件只有1242KB：

變化下的mysqld部分my.cnf中的my.ini或文件，並設置：

max_allowed_packet=100M 

或者你可以在連接到同一臺服務器一個MySQL控制檯運行這些命令：

set global net_buffer_length=1000000; 
set global max_allowed_packet=1000000000; 

對於客戶端，你可以在命令行上指定它：

mysql --max_allowed_packet=100M -u root -p database < dump.sql
