Error 1153 – Got a packet bigger than ‘max_allowed_packet’ bytes. The solution of this error is to change the value of max_allowed_packet’.

Generally, max_allowed_packet is initialized to net_buffer_length bytes, and when we are dealing with large BLOB columns or any long strings like a big database dump or restore, we should also increase the size of max_allowed_packet.

The default value is minimal, and it requires to change for large packets.
When we are changing the value of max_allowed_packet, we should also modify the buffer size on the client side.

Method 1: Under the mysqld section, add or change the value in my.cnf file:

[mysqld]

max_allowed_packet=128M

Method 2: Directly run these commands in the MySQL console:

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