But when I enter /etc/cron.daily/50plesk-daily, to change the lines above, in the SSH extension, there are no options for changing this line?

Could you please be more specific what you mean by not having options to change the line?

 

[calu]

Thank for replying despite the difficulties of posting this topic.

From the screenshot you can see that there is no response when /etc/cron.daily/50plesk-daily is entered.

 

[Peter Debik]

That would be a text file that you can edit with nano or vi for example.
# nano /etc/cron.daily/50plesk-daily

 

[calu]

Thanks, now I'm standing on the line which I need to replace, and I need to make the backslash command to Replace.

The problem is that the backslash key combination on the Mac is Alt + Shift + 7 so it is simply not possible to execute the command,
so how do I replace the line?

Thanks for helping out.

 

[Peter Debik]

Control+Command, then select the character from the character table and copy-paste it maybe. Else I would not know an alternative. You might want to use vi instead of nano, if nano responds to specific key combinations from a Mac.

Hi there, I'm not allowed to edit memory_limit file:

GPT-4 suggests:

1. Open the php.ini file using a text editor such as vi, nano, or gedit.

bashCopy code
vi /usr/local/psa/admin/conf/php.ini

1. Search for the "memory_limit" directive in the file.
2. Change the value of "memory_limit" to "512M" or any other value you want to set. You can replace the existing value by highlighting the existing value with your cursor and typing in the new value.
3. Save the changes and close the file. In vi, type ":wq" (without quotes) to write and quit the file.
4. Restart the Apache web server or PHP-FPM service to apply the changes.
   
   
5. If you are unable to highlight the existing value with your cursor and type in the new value in the php.ini file using your text editor, you can try these alternative steps to replace the existing value:

But it is not possible to edit this value in any of the way described?

 

[Peter Debik]

Could you please be more specific what "not allowed" means? As root user there should be no problem with editing a file. Are you root, did you escalate your privileges with "su", "sudo" to root?

 

[calu]

Yes, I'm root.
What I mend by "not allowed" is that I can't change the memory_limit 256M to 512M with the cursor or by highlighting.

 

[Peter Debik]

I don't think that is anything related to the server, but rather an issue with SSH or your keyboard. You said it was a Mac? Maybe a Mac user on here can help.

 

[Maarten]

The instruction from GPT-4 is incomplete. I've added line 2 and 4:

1. Search for the "memory_limit" directive in the file.
2. Goto into Insert mode by pressing the i key.
3. Change the value of "memory_limit" to "512M" or any other value you want to set. You can replace the existing value by highlighting the existing value with your cursor and typing in the new value.
4. When you're done editing the file, hit Esc key to leave the Insert mode.
5. Save the changes and close the file. In vi, type ":wq" (without quotes) to write and quit the file.
6. Restart the Apache web server or PHP-FPM service to apply the changes.
   
   
7. If you are unable to highlight the existing value with your cursor and type in the new value in the php.ini file using your text editor, you can try these alternative steps to replace the existing value:

Thanks for the suggestions, the values of the text files are red, something tells me that these values can't be edited, not a least because of the notification at the top:

I'm following the documentation from here, not the suggestions from GPT-4:

[calu]

Good news, now the terminal looks like this, and I'm able to change the memory value.

 

[Maarten]

I'm glad you sorted it out using the nano editor!

Remember that your changes will be overwritten the next time Plesk is updated unless you applied point (7.) from the article you mentioned.

 

[calu]

Thanks for reminding me, I did apply point 7, so changes should be saved.

After changing memory_limit to 512M, Plesk panel is extremely slow and I'm experiencing no answer from the page, white screen or time out, when I enter the Docker Redis settings and the log, which I have not experienced before.
Can this be related to the change of memory from 256M to 512M?

 

[Maarten]

It could be that the server is running low on memory.
The easiest way to test this is to change the memory_limit back to 256M

 

[calu]

changing the memory_limit back to 256M the internal error is back, so it is a dilemma.

In the Redis Console Log I get this warning, even though I did change overcommit_memory from 0 to 1 and rebooted.

WARNING Memory overcommit must be enabled! Without it, a background save or replication may fail under low memory condition. Being disabled, it can can also cause failures without low memory condition, see vm.max_map_count growing steadily when vm.overcommit_memory is 2 · Issue #1328 · jemalloc/jemalloc. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
