MySQL 5.7.37 on AaPanel getting automatically stopped frequently, like weekly or so. How/where can I find out what is causing this issue? It is a Pro account and I have Website Statitistics 6.1, Apache WAF 8.8, website tamper-proof etc. already installed. Thanks in advance.

Hello, Can you check whether the total running memory of the configured software exceeds the physical memory? Check mysql's slow logs at the same time

Hi, runjing the above command returns this error: sudo: unable to resolve host DebianVMWPSites1: Temporary failure in name resolution While figuring it out with the IT team, can I enable the "Memory protection" setting? or, enable the cron job "Start MySQL"? Kindly advise.

Recommend to enable this aboobacker

aboobacker sudo: unable to resolve host DebianVMWPSites1: Temporary failure in name resolution

This error is caused by not configuring /etc/hosts pointing to 127.0.0.1

aboobacker

aaPanel_Kern
Thanks. It shows this error when enabling the Daemon:

But, System Hardening is not enabled.

aaPanel_Kern

Try to close System hardening
Or turn off special permissions and add
chattr -i /var/spool/cron/crontabs/root

aboobacker

when runnign this command, it still shows:

sudo: unable to resolve host DebianVMWPSites1: Temporary failure in name resolution

in hosts file I see there is already 127.0.0.1 localhost added.

aaP_kotakomputer.ceo

aboobacker

Just pointing DebianVMWPSites1 to 127.0.0.1 as shown below:

127.0.0.1 localhost
127.0.0.1 DebianVMWPSites1

aboobacker

aaP_kotakomputer.ceo Thanks. It worked 🙂 I have enabled the mySQL Daemon. Will see if it solves the issue. Thanks

Hi, when I check the logs of mysql daemon cron, it shows "btpython - command not found". Is there anything I should do in this case? MySQL server is running fine currently though.

btpython /www/server/panel/script/restart_services.py mysql

aaPanel_Kern

Is it normal to try to generate btpyhon manually?

ln -sf /www/server/panel/pyenv/bin/python3 /usr/bin/btpython

aboobacker

Running the above command shows below error (even with sudo):

ln: failed to create symbolic link '/usr/bin/btpython': Operation not permitted

Is it fine to try the below instead?

sudo ln -sf /www/server/panel/pyenv/bin/python3 /usr/local/bin/btpython

aaPanel_Kern

aboobacker
Yes, you try

aboobacker

aaPanel_Kern Still getting the error:

ln: failed to create symbolic link '/usr/local/bin/btpython': Operation not permitted

FYI - I have these addons installed in AaPanel. Could it be blocked by any of these?

aaPanel_Kern

Are System hardening used?

aboobacker

aaPanel_Kern

No. System hardening is not installed.
