Error while sending QUERY packet——解决办法

You can solve this problem by following few steps:

1) open your terminal window

2) please write following command in your terminal

ssh root@yourIP port

3) Enter root password

4) Now edit your server my.cnf file using below command

nano /etc/my.cnf  

if command is not recognized do this first or try vi then repeat: yum install nano.


  vi /etc/my.cnf 

5) Add the line under the [MYSQLD] section. :

max_allowed_packet=524288000 (obviously adjust size for whatever you need) 
wait_timeout = 100

6) Control + O (save) then ENTER (confirm) then Control + X (exit file)

7) Then restart your mysql server by following command

/etc/init.d/mysql stop
/etc/init.d/mysql start

8) You can verify by going into PHPMyAdmin or opening a SQL command window and executing:

SHOW VARIABLES LIKE 'max_allowed_packet'

This works for me. I hope it should work for you.
