phpredis extension doesn't work, unable to load 'redis.so' - redis

I installed nginx, php, php-fpm, php-pecl-redis by yum.
All of them work but the last one.
When I run /usr/sbin/php-fpm, I got this:
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/redis.so' - /usr/lib/php/modules/redis.so: undefined symbol: igbinary_unserialize in Unknown on line 0
I don't know what igbnary_unserialize means and how to fix it.
I checked the redis.so file under right path. I add extension=redis.so to php.ini
PHP version: 5.3.3
PhpRedis version: 2.2.7


I had the same issue. I'm on Ubuntu 16.04 LTS. Running sudo apt-get install php-igbinary resolved the issue for me. I have other issues, but that's what solved this one.


For people who are upgrading their php from 7.0 to 7.4 like me, and not able to get php-redis working. These are the steps I used after following the answers above.
1) remove Redis
sudo apt purge php-redis
2) Install Igbinary
sudo apt-get install php-igbinary
3) Install php-redis again
sudo apt-get install php-redis
I did the steps above because it seems only php7.0 is recognising the php-redis install but not the currently enabled php7.4
I also recommend removing other versions of PHP if you have should your problem continue unsolved.


Probably an issue with igbinary, is this installed? (try for example: cat /etc/php.d/igbinary.ini).
Here you can find and install igbinary


Related to this bug https://bugs.launchpad.net/ubuntu/+source/php-redis/+bug/1762935
You should remove php-redis from packages:
apt purge php-redis , and install it via pecl install redis
You should add "extension=redis.so" to php.ini
and remove redis from config.d in your php directory:
rm /etc/php/7.2/fpm/conf.d/#20-redis.ini
and
rm /etc/php/7.2/cli/conf.d/#20-redis.ini
restart php fpm and you will see that problem solved


On Ubuntu 20 and PHP 7.4
I did this and it worked :
sudo apt purge php-redis
sudo apt intall php-redis php7.4-redis
TEST redis server :
$ php --ri redis
or
$ redis-cli ping
$ redis-cli info stats


just resolve the same problem:
php-pecl-redis installed by yum will cause this problem.
so you need to install the php-redis manually. wget the package and phpize - configure - make ....

Apache2 uninstall issues

I had to recently uninstall Apache2 due to some broken package issues.
However, when I check with
`$ whereis apache2` Iget response `apache2:`
I have used $ sudo -rf /etc/apache2,$ sudo apt-get remove apache2-common
$ sudo apt-get --purge remove apache2 $ sudo apt autoremove but I have still not managed to completely remove all traces of the Apache2 from my Linux Mint 19.3 Cinnamon.
I shall highly appreciate if someone guide me in the right direction.

According to the commands above you completely removed Apache2.
apt remove removes the binaries of a package
apt purge removes everything related to the apache2 package including the configuration files.
In your case whereis is showing that there are no binaries, sources or manual pages of the apache2 package.

How to install gearman extension in php7 running on ubuntu 18.04

I am currently required to setup the new server running php7.2 and the server will have many background process for sending emails to customer. the recommendation I got was to use Gearman Job Server.
I have been searching but seems to have only post about gearman-job-server with php5 and below.

The process of installing Gearman Job Server with php7 will be covered in like 4 steps
Install and update the Gearman PPA
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:gearman-developers/ppa
sudo apt-get update
Install Gearman Job Server and some other required components and tools
sudo apt-get install gearman-job-server libgearman-dev php7.0-dev php-pear wget unzip re2c
sudo apt-get upgrade
Download, compile the gearman pecl module and add to php.ini
cd /tmp/
sudo wget https://github.com/wcgallego/pecl-gearman/archive/master.zip
unzip master.zip
cd pecl-gearman-master
sudo phpize
./configure
sudo make
sudo make install
echo "extension=gearman.so" | sudo tee /etc/php/7.0/mods-available/gearman.ini
sudo phpenmod -v ALL -s ALL gearman
Restart webserver or PHP FPM
sudo service php7.0-fpm restart
sudo service apache2 restart
If you are running a different version of PHP make sure you make the appropriate changes to the commands or directories mentioned above. ie “/etc/php/7.0/” to “/etc/php/7.1/” etc.
Thanks to techearl.com for their tutorial which can be found
Here

The answer by Ruberandinda Patience is correct and will work but since the gearman pecl module is packaged for Ubuntu there is a much simpler way to achieve the same thing:
apt install gearman-job-server php-gearman

Apache doesn't start in AMPPS on Ubuntu

I'm trying to run the Ampps local server 3.8 on Ubuntu. Mysql works good but apache doen't run.
When I type
/usr/local/ampps/apache/bin/httpd
I get
/usr/local/ampps/apache/bin/httpd: symbol lookup error: /usr/local/ampps/apache/lib/libapr-1.so.0: undefined symbol: dlopen
How to solve?

I experienced a similar problem. Firstly you must check is there anything that uses 80 port.
If any you kill that.
Then you backup libapr and then install libs again.
Run following commands:
cd /usr/local/ampps/apache/lib
sudo mkdir backup
sudo mv ./libapr* ./backup/
sudo apt-get -y install libaprutil1 libaprutil1-dev libapr1 libapr1-dev
and try run ampps.

Facing error while installing Apache2 in Ubuntu 14.04 'has no installation candidate'

I don't know what I did but I'm not able to install apache2 in my Ubuntu 14.04.
When I use sudo apt-get install apache2 I face this error.
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package apache2 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
libapache2-mpm-itk:i386 libapache2-mpm-itk
E: Package 'apache2' has no installation candidate

First make sure that your proxy is disabled as that can cause a problem sometimes.
Then run the following.
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install apache2
If that doesn't work you can always compile your own apache2. A tutorial for that is located here: https://www.virgohacks.net/install-apache-2-4-mysql-5-6-php-5-5-source-ubuntu-14-04/
Good luck

mCrypt not present after Ubuntu upgrade to 13.10

After I have upgraded my system from Ubuntu 13.04 to 13.10 several problems have occurred with apache, mysql and php configurations.
I solved most of them but I can't seem to get mCrypt library working.
Package is installed so i don't need to apt-get it. Server works and everything seems fine, but when I try to run php artisan serve with Laravel 4, I get a message that mCrypt is required.
I did php --ri mcrypt and the output was Extension 'mcrypt' not present.
I have tried putting extension=mcrypt.so to /etc/php5/apache2/php.ini but it didn't work.
Any ideas?
Output of dpkg --get-selections | grep php5
libapache2-mod-php5 install
php5 install
php5-cli install
php5-common install
php5-gd install
php5-json install
php5-mcrypt install
php5-mysql install
php5-readline install

I think I found the solution at launchpad.net.
sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available
sudo php5enmod mcrypt
sudo service apache2 restart
This worked for me.

I had this problem with Ubuntu 14.04 and I did the following to resolve it:
sudo apt-get install php5-mcrypt
sudo php5enmod mcrypt
sudo service apache2 restart

I also have this problem with Ubuntu 14.04 after install.
First enable the mcrypt
sudo gedit /etc/php5/apache2/php.ini
Add this command in any line
extension=mcrypt.so
Create conf.d folder in /etc/php5
sudo mkdir conf.d
And inside that folder create mcrypt.ini file
sudo gedit mcrypt.ini
Then add this command to that file
extension=mcrypt.so
Then create a link to file
sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available
Enable mcrypt module
sudo php5enmod mcrypt
Restart apache
sudo service apache2 restart

From Ubuntu 13.10 to 14.04:
sudo php5enmod mcrypt
sudo service apache2 restart
Works for me.

I also had this problem with Ubuntu 14.04 and Nginx,but the tip for me was restart the FPM service, so I did:
Install the library
apt-get install php5-mcrypt
Find the path
updatedb && locate mcrypt.so
Set the path of mcrypt.so inside the mcrypt.ini file located in /etc/php5/mods-available/mcrypt.ini
extension=/usr/lib/php5/20121212/mcrypt.so
And then restart the FPM service
service php5-fpm restart

Another solution if the package is already installed:
sudo aptitude reinstall php5-mycript
This worked for me after doing upgrade

Try this code:
ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/apache2/conf.d/20-mcrypt.ini
service apache2 restart

I had the same problem with PHP 5.5.14 running on Mac OS X Yosemite. I was trying to install Laravel 5.0. And when I tried to create a new project I got an error like below (even when I tried to start the laravel server with php artisan serve
Alejandros-MacBook-Pro:Documents Lexynux$ laravel new blog

So I just added the line below at the end of my php.ini file with the nano editor:
extension=mcrypt.so
sudo nano /etc/php.ini
Finally just restart the Terminal and restart the laravel app server with
php artisan serve
And it works fine!

just found on php.net
Note, for Ubuntu, simply installing php5-mcrypt did not get mcrypt to work. You need to execute the following commands as root to enable it:
apt-get install php5-mcrypt
mv -i /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available/
php5enmod mcrypt
service apache2 restart
http://php.net/manual/en/mcrypt.installation.php#114609

Sometimes, this "problem" occurs because you entered an artisan command on your local machine instead of on your virtual machine. If you are using Homestead, mcrypt is already installed. Consider it a reminder to homestead ssh
