Resolved How to install Zeromq

[a.prevost]

Hello,

I am trying to install the zeromq extension on plesk onyx, but I can not do it.
I have been looking for a few days, but to no avail.

My plesk is installed on Centos7,
I think I managed to install it at the root, but I can not find it in the php extensions on plesk.

I have not found a specific tutorial on this subject, if someone can help me Or if someone knows a detailed tutorial

PS: sorry for my english, i'm french ;-)

Please try to use following steps for installing zmq php extension:

# yum install plesk-php71-devel gcc make
# wget https://github.com/zeromq/libzmq/releases/download/v4.2.3/zeromq-4.2.3.tar.gz
# tar -xzf zeromq-4.2.3.tar.gz
# cd zeromq-4.2.3/
# ./configure --prefix=/usr
# make
# make install
# /opt/plesk/php/7.1/bin/pecl install zmq-beta
# echo "extension=zmq.so" > /opt/plesk/php/7.1/etc/php.d/zmq.ini
# cp /usr/lib/libzmq.so.5 /usr/lib64/
# plesk bin php_handler --reread

After that check that zmq php extension is successfully loaded:

# /opt/plesk/php/7.1/bin/php -m | grep zmq
zmq

Hello,

You are my savior !!

I looked a little, because it did not work, but it must be due to my previous tests. but after uninstalling the previous versions I tried to install it works now thanks to you !!!

Really, thank you !!!

I have a PHP warning:
PHP Warning: PHP Startup: Unable to load dynamic library '/opt/plesk/php/7.1/lib/php/modules/zmq.so' - /opt/plesk/php/7.1/lib/php/modules/zmq.so: cannot open shared object file: No such file or directory in Unknown on line 0

How fix it?
Thanks!

Have you installed the module according to instruction Resolved - How to install Zeromq ? Do you really have /opt/plesk/php/7.1/lib/php/modules/zmq.so file there?

I tried this on ubuntu setup
ran first command as sudo apt install plesk-php73-dev

line ./configure --prefix=/usr gives following error
configure: error: Unable to find a working C++ compiler

Why only plesk-php73-dev? What about necessary make and gcc?

They are already installed

 

[IgorG]

They are already installed

Try

# apt install build-essential

 

[harpreetsb]

Try

# apt install build-essential

should make and make install run with sudo?

make install gives following error
/usr/bin/install: cannot create regular file '/usr/share/man/man3/zmq_version.3': Permission denied

 

[IgorG]

All commands in my instruction above were executed under root account (see # prompt).
So, you can login as root or use sudo.

Try to use my instruction step-by-step after login as root (without sudo).

 

[harpreetsb]

I am using zeromq-4.3.4 that should not be a problem right?

 

[harpreetsb]

Well I don't have root access.

 

[IgorG]

No, I successfully compiled zeromq-4.3.4 on Ubuntu with:

# apt install build-essential
# wget https://github.com/zeromq/libzmq/releases/download/v4.3.4/zeromq-4.3.4.tar.gz
# tar -xzf zeromq-4.3.4.tar.gz
# cd zeromq-4.3.4/
# ./configure --prefix=/usr
# make
# make install

But there is a problem on the stage of compiling PHP module with the pecl:

# /opt/plesk/php/7.3/bin/pecl install zmq-beta

Looks like some kind of incompatibility.

 

[harpreetsb]

Should I try an older version?

I tried with the same result of compiling PHP module.
Strange but it works fine on CentOS but not on Ubuntu/Debian.

Damn we need this module to go live in next few days.
hope this can be resolved by some means.
will updating to php7.4 help?

 

[IgorG]

I found a solution. You have to compile PHP module from the master branch:

# apt-get install --yes git libzmq3-dev
# git clone git://github.com/mkoppanen/php-zmq.git
# cd php-zmq/
# /opt/plesk/php/7.3/bin/phpize
# ./configure --with-php-config=/opt/plesk/php/7.3/bin/php-config
# make
# make install
# echo "extension=zmq.so" > /opt/plesk/php/7.3/etc/php.d/zmq.ini
# plesk bin php_handler --reread

As result:

# /opt/plesk/php/7.3/bin/php -m | grep zmq
zmq
