During the operation, an error of mysql server has gone away may occur. This is caused by too large database, insufficient cache or operation timeout. You can modify the configuration of mysql to solve this problem:

1. Open the configuration file (shown here is the configuration file under brother Jun's lnmp. If your path is not this, find it yourself) CVM

Vi / etc/my.cnf

2. Find the two variables wait_timeout and interactive_timeout, and set the value to

Wait_timeout=2880000

Interactive_timeout = 2880000

If you don't have these two parameters, you can add them directly.

3. Find max_allowed_packet and increase the value of this variable, such as 100m (you can also set the size you want)

Max_allowed_packet = 100m

The max_allowed_packet parameter is used to control the maximum length of its communication buffer.

Of course, other parameters can be adjusted according to your own needs:

4. Restart the mysql service.
