[solved] Add memcached to fcgi PHP

[Elompenta]

I tried to add memcached to my - from plesk additional delivered - PHP Version 5.5 fcgi with the following notice from knowledgebase

http://kb.odin.com/de/125146

If i install all packages and install the Extension via pecl the followin error ecours:

checking whether libmemcached supports sasl... no
configure: error: no, libmemcached sasl support is not enabled. Run configure with --disable-memcached-sasl to disable this check
ERROR: `/tmp/memcached/configure --with-libmemcached-dir=no' failed

Any ideas how i can fix this issue and install memcached to my fcgi?
Here my full Output

Try to do following:

# yum install cyrus-sasl-devel

and then run

# /opt/plesk/php/5.5/bin/pecl install memcached

Sorry i missed this information - it was a Debian machine
the packet "cyrus-sasl-devel" does not exist in Debian

if i search i found the following:

Ehm, first you stated

PHP Version 5.4 fcgi

and then you stated

/opt/plesk/php/5.5/bin/pecl install memcached

and I am just wondering whether you are using the wrong directory or the wrong php version.

Anyway, if you follow the procedures I have written in this DevBlog article you would be creating the memcached (pecl) extension properly.

If I am not mistaken, you can easily add the extension to PHP 5.4 by running the command: echo “extension=memcached.so” > /opt/plesk/php/5.4/etc/php.d/memcached.ini

Afterwards, do an Apache restart (for the sake of convenience).

And then you should be able to go to the PHP settings in your Plesk Panel and enable the memcache module by checking the appropriate checkbox.

Note that you should verify whether the memcache module works properly, all the above has not been tested by me (but it should work like a charm).

Regards.....

@trialotto
thanks for your information! - it was a typo in my first post. I've correct them
The correct Version is PHP 5.5

I have already found your articel - but it doesnt works on Debian. Some packets called unter a other name i think

root@venus:~# apt-get install make plesk-php55-devel gcc glibc-devel libmemcached-devel zlib-devel
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package plesk-php55-devel
E: Unable to locate package glibc-devel
E: Unable to locate package libmemcached-devel
E: Unable to locate package zlib-devel

I think i have installed all needed Debian packages, but i recieve all the time the following sasls error

checking whether libmemcached supports sasl... no
configure: error: no, libmemcached sasl support is not enabled. Run configure with --disable-memcached-sasl to disable this check
ERROR: `/tmp/memcached/configure --with-libmemcached-dir=no' failed

sasl is installed and work - any idea how i can fix this this error in memcached installation?

thanks for your help!

@Elompenta

Really, do NOT run a command like your apt-get command: that will NEVER work.

Follow the exact steps from the DevBlog article, in the directories described in that article and run the echo command:

a) echo “extension=memcached.so” > /opt/plesk/php/5.5/etc/php.d/memcached.ini

OR (if the above does not work)

b) echo “extension=<path to library>/memcached.so” > /opt/plesk/php/5.5/etc/php.d/memcached.ini

with <path to library> set to the location of the memcached.so file (note that it is safer to use option b from the start).

Furthermore, note that you have to be AWARE of the facts that

- you have a major issue with your repositories: run apt-get update before you start doing anything
- it is best to uninstall all packages from the previous attempts: otherwise, the old packages can cause problems

In essence, the memcached installation process also works on Debian, but your issues with repositories and old (probably broken) packages do cause problems.

Regards...

 

[Elompenta]

mmhh i dont understand your solution..

I've found an existing memcached.so on the disk

root@venus:~# updatedb
root@venus:~# locate memcached.so
/usr/lib/php5/20100525/memcached.so
/usr/lib/x86_64-linux-gnu/libmemcached.so
/usr/lib/x86_64-linux-gnu/libmemcached.so.10
/usr/lib/x86_64-linux-gnu/libmemcached.so.10.0.0

If i create the additional ini file with the following command

root@venus:~# echo "extension=/usr/lib/php5/20100525/memcached.so" > /opt/plesk/php/5.5/etc/php.d/memcached.ini
root@venus:~# plesk bin php_handler --reread
The information about PHP handlers was successfully updated.
root@venus:~# /etc/init.d/apache2 restart
[ ok ] Restarting web server: apache2 ... waiting .

I will find the error on apache error log

PHP Warning:  PHP Startup: memcached: Unable to initialize module
Module compiled with module API=20100525
PHP  compiled with module API=20121212
These options need to match
 in Unknown on line 0

Vendor PHP Version is PHP 5.4, so i think i need to install PHP 5.5 compatibel Version via $ pecl install or not?

@trialotto
Do you have any idea to get the extension working?

I have no solution at this moment.
I will open a Plesk Ticket by Support Team - hope they are able to help

thanks

 

[Elompenta]

If i build the extension via pecl with the statement "--disable-memcached-sasl" building works fine

Build process completed successfully
Installing '/usr/lib/php5/20100525/memcached.so'
install ok: channel://pecl.php.net/memcached-2.2.0
configuration option "php_ini" is not set to php.ini location
You should add "extension=memcached.so" to php.ini

If i now add the following php.ini

echo "extension=/usr/lib/php5/20100525/memcached.so" > /opt/plesk/php/5.5/etc/php.d/memcached.ini
plesk bin php_handler --reread
/etc/init.d/apache2 restart

i get the following error in the apache error log

PHP Warning:  PHP Startup: memcached: Unable to initialize module
Module compiled with module API=20100525
PHP  compiled with module API=20121212
These options need to match
 in Unknown on line 0

any ideas?
I hope forum or support can help in this issue

thanks so much

@Elompenta

Give me the version of PHP, for which you want the memcached module. Ok?

Regards.....

 

[Elompenta]

@trialotto
thanks so much - PHP Version 5.5.31 as Fast CGI

 

[trialotto]

@Elompenta,

The module is attached, note that the modules has not been tested thoroughly: play with it and let me know.

You are a very great guy! thanks so much

Just for Info - The Support Case
-------

Hello,

I was able to build memcached module for php5.6.
Here's how this was achieved:

1. First and foremost, please retrieve new lists of packages



# apt-get update
2. # apt-cache search plesk-php | grep dev



>>plesk-php55-snmp - A module for PHP applications that query SNMP-managed devices
>>plesk-php55-dev - Files needed for building PHP extensions
>>plesk-php56-snmp - A module for PHP applications that query SNMP-managed devices
>>plesk-php56-dev - Files needed for building PHP extensions
3. # apt-get install build-essential

4. # apt-get install make plesk-php55-dev gcc libc-dev libmemcached-dev zlib1g-dev pkg-config

pkg-config distribution is not mentioned in the guide(considering a RH-based system is used as an example there) but is essential to build the module.

5. Then, when you run:



# /opt/plesk/php/5.6/bin/pecl install memcached
when prompted for the libmemcached directory type "no --disable-memcached-sasl":



>> libmemcached directory [no] : no --disable-memcached-sasl
This is important. Otherwise the following will be thrown:



>>configure: error: no, libmemcached sasl support is not enabled. Run configure with --disable-memcached-sasl to disable this check
>>ERROR: `/tmp/memcached/configure --with-libmemcached-dir=no' failed
6. register the handler with Plesk:



# echo "extension=memcached.so" > /opt/plesk/php/5.6/etc/php.d/memcached.ini
# plesk bin php_handler --reread
7. Now you can go to Tools & Settings > PHP Settings > *any PHP 5.6 handler* and confirm that the memcached module is enabled for a particular handler

==========================================

As for php5.5, I couldn't install plesk-php55-dev because of unmet dependencies:



>>The following packages have unmet dependencies:
>>plesk-php55-dev : Depends: plesk-php55 (= 5.5.30-debian7.0.15102116) but 5.5.31-debian7.0.16011212 is to be installed
>>E: Unable to correct problems, you have held broken packages.
My guess - it has something to do with Plesk repository issues.
I have already requested assistance from our developers to sort this issue out. We will get back to you on Tue, Feb 2 regarding this matter.

So, for now you can build memcached module for php5.6 as a workaround of a kind.

@Elompenta,

What do you mean with the "Just for Info - The Support Case"? Did you ask Plesk Support or..... ??

[Elompenta]

Did you ask Plesk Support or..... ??

@trialotto
Yes, i have created a Plesk Ticket - The PLesk Support Team are also not able to install memcached for PHP 5.5 at the moment on current release.
They work on a fix for this.

 

[trialotto]

@Elompenta,

That is not surprising, given that the PHP stack (currently installed with Plesk) does contain some items that are not fully compatible with PHP version 5.5.

However, a work-around should can be easily found, by simpy creating a "clean" PHP environment, just as I did, when compiling the memcached modules.

As a separate (i.e. completely independent of the above) remark: be aware that memcached is

- a little bit limited (in many dimensions, as opposed to Redis, (and)
- more difficult to work with, as opposed to Redis (certainly when using the Redis module based upon phpredis), (and)
- associated with a memcached module, that can be buggy (due to the fact that the source code of that modules is not that good, when compared to code for the Redis module)

and even though all is "relative", I would strongly advice to use the Redis Cache approach, in stead of memcached.

Naturally, Redis can also be used with PHP 5.5.

Regards.....

@trialotto

Plesk Support has find and fixed this issue:

--
We have fixed the issue with plesk-php55-dev packet.
There was a redirection problem with our repository http://autoinstall.plesk.com/

Now you can follow the same procedure for php 5.5
Let me know in case you have any other questions.

[trialotto]

@Elompenta,

Then I suggest you compile the module via "pecl install", since that is the less error-prone method.

Note that, if you run the "pecl install" command from both the ../php/5.5/bin and ../php/5.6/bin paths, you still have to verify that the appropriate modules are compiled an installed.

Regards....
