Enable APCu

[Bogdan1]

Hey,

I installed APCu using pecl

"pecl install apcu"

APCu was installed successfully, but I can't enable it.
I created apcu.ini in : /opt/plesk/php/5.6/etc/php.d
apcu.ini contains this rows:

extension = apcu.so
apc.enabled=1
apc.shm_segments=1
apc.shm_size=128M
apc.ttl=3600
apc.user_ttl=7200
apc.gc_ttl=3600
apc.max_file_size=2M
apc.stat=0

Could you help me to enable it? Thanks

PS: In phpinfo(); I see included apcu.ini, but extension isn't enabled.

Ok, APCu works on php 5.4, but if I switch on the 5.6, APCu turns off.

 

[Bogdan1]

? any ideas ?

 

[Bogdan1]

hmm thanks for help ...

You have to install the extension in the context of the target php version.

Have a look at this post - you can simply adjust the script for your needs or run the corresponding parts manually.

Thanks, but how to install php-devel for all php versions? Sorry i'm new in linux

 

[Oliver Meyer]

Maybe the devel-packages are already installed on your system - since MU51 the devel-packages are not longer available for manual download.

You can check if they are already installed via...

yum list installed | egrep "^plesk-php[0-9]{2}-devel"

or

dpkg -l | egrep "^plesk-php[0-9]{2}-devel"

depending on your distribution.

EDIT: Just tested it with a fresh virtual machine - the devel packages are not installed by default and not longer available for download (access forbidden).

Oh, but how to install extensions now? I want to use php 5.6, but APCu works only for php 5.4.

Seems that you have to wait till the Plesk-guys permit the download of the devel-packages again.

Already fixed.

Could you explain how to install php-devel manually, please? I'm new in linux. Thanks for helping

For example:

# yum install plesk-php56-devel
# yum install plesk-php54-devel

 

[Oliver Meyer]

The devel packages are not available via package manager - just tested it again in my test-vm.
So you would have to do it manually.

Example for PHP 5.6.10:

#1 - Open http://autoinstall.plesk.com/PHP_5.6.10/ in your browser and determine the full url of the devel-package for your distribution, e.g. CentOS 7:

http://autoinstall.plesk.com/PHP_5....hp56-devel-5.6.10-centos7.15061519.x86_64.rpm

#2 - Download & install

cd /tmp
wget http://autoinstall.plesk.com/PHP_5....hp56-devel-5.6.10-centos7.15061519.x86_64.rpm
yum install plesk-php56-devel-5.6.10-centos7.15061519.x86_64.rpm

Note: If you are running debian or a debian based distribution, the command would be 'dpkg -i ...'

Hmm... yum installation works fine on my tests Plesk 12 server.

 

[Oliver Meyer]

On CentOS 7 there is not even a plesk/odin repository - don't know about CentOS 6.

 

[RuslanT]

Plesk installer adds the Plesk PHP repositories only for period when it is installing packages. If you want to install plesk-php*-devel packages you need to install them manually as described above. Once installed plesk-php*-devel packages will be updated by plesk-installer automatically on every new Plesk PHP release.

 

[Bogdan1]

Thanks, everything works now.

Hello,

we have followed the instructions of Oliver Meyer, but still experience the same problem of Bogdan1. apcu.ini is loaded, which I can see in the phpinfo(), but the module is not beeing loaded.

Would you please tell the steps one does have to follow? I am pretty sure that only installing all devel packages does not solve the problem.

Kind regards

Chris

Are you sure, that you have installed apcu in the context of the desired php version?

E.g. (for php 5.6.10, untested):

1. Install the corresponding php devel-package
2. Install apcu in the context of the right php-version:

cd /opt/plesk/php/5.6/bin
./pecl config-set php_ini /opt/plesk/php/5.6/etc/php.ini
./pecl config-set php_bin /opt/plesk/php/5.6/bin/
./pear config-set php_suffix ""
./pecl install --force apcu

3. Include the apcu-extension

echo "extension=apcu.so" > /opt/plesk/php/5.6/etc/php.d/apcu.ini

4. Restart Apache

service httpd restart
or
service apache2 restart

5. Configure the desired vhost to use apcu

apc.enabled = 1
...

Hello Mr. Meyer,

thank you for your instructions. The problem is solved now.

After using "./pecl config-set php_ini /opt/plesk/php/5.6/etc/php.ini" i received an error, that the file apcu.so is not available. So I have used your instructions to install it in the right context, restarted apache and it worked perfectly.

Thank you very much.

Kind regards

Chris
