Resolved Memcache install failed

[Dukemaster]

Hi at all,
memcached for 7.1 I had successfully installed since few months.

root@server:~# /opt/plesk/php/7.1/bin/php -i | grep "memcached support"

=> memcached support => enabled
Now, i wanted to complete the feature by installing also memcache.
I followed the same good plesk tutorial for memcache+memcached installation like weeks ago (for memcached 7.0 + 7.1).
For command

/opt/plesk/php/5.6/bin/pecl install memcache

I changed 5.6 to 7.1
But I got the following error:

/tmp/memcache/memcache.c:40:40: fatal error: ext/standard/php_smart_str.h: No such file or directory

For sure I tried to find a solution here in PLESK forum, articles, support and on internet.
I found several answers, but they won't really say how to fix the problem, especially not with Plesk, some are for redis.
Does someone knows how and if it's possible to fix the installation? Please, remember that I use "only nginx" configuration without apache. I think that this time this is not important, but to be sure.

Additional question:
The configuration of Woltlab software says (visible in the screen):



You can specify a weight factor to allow load balancing, for example “localhost:11211:67” or “10.0.13.37:31337:33”. Enter one server per line.

I don't really know if this configuration is always the same, especially the weight factor. How to get the correct values, nor where to change, if it's necessary? Or if it's possible to take exactly the first one for example.

Lots of greets.

Would be great if someone could give me a little help or inspiration.
I have installed memcached in PHP FPM 7.0 and 7.1 but there seems missing something.
Is the error that I'm using only nginx without apache in domain settings? Perhaps the special nginx release with incredible pagespeed?
But I won't get on @UFHH01 nerves by asking again.
When I insert localhost:11211:67 in the box of Cached in Woltlab admininstration panel and apply
the side load seems slower. Think I perhaps have to configure something else in Plesk or memcached / PHP.ini.
In FPM and FastCGI PHP settings the box memcached is visible and checked (also Redis but with redis also nobody could tell me how to configure the docker container properly).
Memcached is also shown in my phpinfo.php of the domains:

memcached
memcached support    enabled
Version     3.0.0b1
libmemcached version     1.0.18
SASL support     no
Session support     yes
igbinary support     no
json support     no
msgpack support     no

BUT I realized something what makes me wondering. Each value in phpinfo of Local and Master is the same.
Only one is different. Don't know if it's normal, and if not how to fix it? But it has nothing to do with memcached.

Hi Dukemaster,

root@server:~# ps aux | grep memcache
root 16618 0.0 0.0 14224 940 pts/0 S+ 18:09 0:00 grep --color=auto memcache

root@server:~# netstat -tap | grep memcached
root@server:~# netstat -ap | grep 11211

Do you notice, that there is no memcached - server running?
Did you install it?
Did you start it?

You installed the PHP - modules, but pls. keep in mind, that this doesn't automatically install the memcached server.

 

[Dukemaster]

Okay. I had so often the great Plesk article How to install/uninstall memcache and memcached PHP modules on Plesk server? could be really possible that in one long night I only thought to have been installed it, but not in real. But I must say, I think I have.
I will try now again. Thanks a lot @UFHH01

 

[Dukemaster]

Hi @UFHH01 I have little problems.
memcache is not possible to install. Don't know if it's necessary.

esk/php/7.0/include/php/ext/date/lib -DHAVE_CONFIG_H -g -O2 -c /tmp/memcache/memcache.c  -fPIC -DPIC -o .libs/memcache.o

When I start the memcached version for PHP 7.0 and PHP 7.1 then it asks:
libmemcached directory [no] : Here I hit only return. (No Y or N)

root@server:~# /opt/plesk/php/7.1/bin/pecl install memcached

In the middle it says

----------------------------------------------------------------------
Libraries have been installed in:

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the 'LD_RUN_PATH' environment variable
     during linking
   - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to '/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------

and this is the end information:

Build process completed successfully
Installing '/opt/plesk/php/7.1/lib/php/modules/memcached.so'

configuration option "php_ini" is not set to php.ini location
You should add "extension=memcached.so" to php.ini
Illegal instruction (core dumped)
root@server:~# ^C

Hope it's okay. If so, I only have to insert extension=memcached.so in my php.ini under extensions, like I did with geoip..etc...
root@server:~# echo "extension=memcached.so" > /opt/plesk/php/7.1/etc/php.d/memcached.ini
root@server:~# echo "extension=memcached.so" > /opt/plesk/php/7.0/etc/php.d/memcached.ini
plesk bin php_handler --reread
How can I check if installation was successful? Same commands like I posted three postings before?

Greets and Thanks

Greets.

 

[Dukemaster]

YESSSSSS Thanks again @UFHH01
/opt/plesk/php/7.0/bin/php -i | grep "memcached support"
memcached support => enabled
/opt/plesk/php/7.1/bin/php -i | grep "memcached support"
memcached support => enabled

Now would be one question. What is with the 3rd value to put in Woltlab configuration :67
or another number. How is this important?

Hi, @UFHH01 by logging in Woltlabs communitiy ACP I get

502 Bad Gateway
nginx


But Forum itself is free. It seems only problems by admin panel. Do you have an idea what to do now?

 

[UFHH01]

Hi Dukemaster,

pls. delete the ACP cache and the cached templates ( folder: compiled ) and pls. keep again in mind, that Woltlab products ARE not related to any Plesk product at all. You might get support for it at the forum

=> Home > Forum > General Discussion > Open Topics​

... from Plesk Community users, but not at Plesk - related forums!

In addition, you should start to investigate issues with the help of your log - files, as the logs contain much more than a single error message.

 

[Dukemaster]

Yes, I remembered, but it was too late. It had worked from alone. Perhaps a cronjob did it. BUT.
Sorry, again wrong place, I know. But on the other hand it doesn't refer directly to Woltlab, more to memcached alone.
I made my configuration and forum is slower. BUt I will open a new thread for it, like you adviced. And I also delete the caches now in forum.
Thanks
