I try to run php7.4 in ubuntu 21.10 but I get this error.
apache2: Syntax error on line 146 of /etc/apache2/apache2.conf: Syntax error on line 3 of /etc/apache2/mods-enabled/php7.4.load: Cannot load /usr/lib/apache2/modules/libphp7.4.so into server: /usr/lib/apache2/modules/libphp7.4.so: cannot open shared object file: No such file or directory
Missing libphp7.4.so
I installed libphp7.4-embed but the problem persists. The files are installed in /usr/lib/ not in /usr/lib/apache2/modules/. Symbolic link did not help (undefined symbol: php7_module).
How to make php7.4 run in ubuntu 21.10?
I try some commands
$ sudo a2enconf php7.4-fpm
Conf php7.4-fpm already enabled
$ sudo a2enmod php7.4-fpm
ERROR: Module php7.4-fpm does not exist!
Both OP and #Andrew have pieced together a good solution, but since I just had to do this, let me put it all together, with a few extra clarification steps.
First: What version of PHP do you have now / will you use?
php -v
Returns PHP 8.1.2 so 8.1 in my case.
Next, disable the existing apache2 module that was giving you trouble:
sudo a2dismod php7.4
Finally, enable the one you found above:
sudo a2enmod php8.1
Restart apache2 and you're all set.
sudo systemctl restart apache2
after much try and error:
rm /etc/apache2/mods-enabled/php7.4.load
Now it works.
(there is only one php* in mods-enabled: php7.4.conf. I don't know if it matters.)

On a completely fresh ubuntu 18.04 VM I tried to install opam:
$ wget https://github.com/ocaml/opam/releases/download/2.1.0/opam-2.1.0-x86_64-linux
$ mv opam-2.1.0-x86_64-linux opam
$ chmod 777 opam
$ ./opam init
And here is the error I got
<><> Fetching repository information ><><><><><><><><><><><><><><><><><><><><><>
[ERROR] Could not update repository "default": OpamDownload.Download_fail(_,

How should I solve this?
I ran into the same issue and I found a workaround on the OCaml forum: here. (Credits to UnixJunkie)
You can run:
opam init github git+https://github.com/ocaml/opam-repository.git
This should avoid the certificate issues. This worked for me.
I tried to fix the certificate issues using this answer as well. You could try doing that, but it seems complicated when the workaround is to simply point it to the github repo directly.
Update
The reason opam init failed for me was because curl was installed with snap on my system.
Try to run opam init -verbose and that could reveal more about why you ran into an error.
In my case I needed to install other things with opam and it kept failing every time. So snap uninstall curl and then sudo apt install curl fixed things. (Was only able to figure this out with the help from my professor)
I have a 8GB droplet on digitalocean. We launched our site today and we got intense traffic, we have about 3000 concurrent users.
I tried to raise the amount of concurrent connections (with the advice of apache2buddy) but the suggested MaxRequestWorkers to be 482. Here is the file:
<IfModule mpm_prefork_module>
ServerLimit 482
StartServers 5
MinSpareServers 5
MaxSpareServers 10
MaxRequestWorkers 482
MaxConnectionsPerChild 0
</IfModule>
Apache2 uses mdm_prefork and we have read that it's better if we use mdm_worker.
So i tried to disable mdm_prefork, so that I can enable mdm_worker:
a2dismod mpm_prefork
And I got the following error:
ERROR: The following modules depend on mpm_prefork and need to be disabled first: php7.3
What do I have to do to enable mpm_worker?
I found the possible solution to resolve this on my ubuntu server, dont know whether you are running ubuntu as well on your side, but I feel that the steps that I have taken will be the same for almost all distros with change in 1 step where you need to install a new package and the command for that may change based on the distro that you are using.
so the first step is
$ sudo a2dismod php7.3 mpm_prefork
This will disable the prefork module but before that it will disable the php7.3 module to stop the dependency error from occurring.
Next, we enable the worker module
$ sudo a2enmod mpm_worker
Now, the output would suggest that you restart the apache web-server. So, we do the same
$ sudo systemctl restart apache2
Now, if you go to check your website homepage, it may either throw an error or may load a blank page.
So, how do we resolve that; I scoured multiple community forums and found a solution related to the same but it was for freebsd platform so tried the same on ubuntu with some tweaks required to be made on ubuntu side for the steps to work.
The Solution based on ubuntu OS :
First of all, we enable the proxy, proxy_fcgi and setenvif module followed with a php-fpm package installation corresponding to your php version
$ sudo a2enmod proxy
$ sudo a2enmod proxy_fcgi
$ sudo a2enmod setenvif
$ sudo apt-get install php7.3-fpm -y
the php7.3-fpm installation command is the one where you may need to check the installation steps based on the Distro you are using.
Once, php-fpm service is installed you need to make sure that it gets enabled and then start it, so for that
$ sudo a2enconf php7.3-fpm
$ sudo systemctl enable php7.3-fpm.service
$ sudo systemctl start php7.3-fpm.service
Once, the php-fpm service starts successfully, just restart apache service to make sure all the made changes take effect properly
$ sudo systemctl restart apache2
After these steps are taken, please check/refresh your website homepage and the error page or the blank page will change to the proper website page.
The End-Result; your website has shifted from using prefork module to worker module to handle requests.
Also, if you want to switch to event module instead of worker module; just enable event module in place of worker module in the second step; the one that you will take after disabling php7.3 and prefork module
replace
$ sudo a2enmod mpm_worker
with
$ sudo a2enmod mpm_event
rest all steps after that remain the same irrespective of enabling worker or event module.
These steps helped me switch from prefork module to worker module on my server so hoping it may help you as well as help others who stumble on this issue.
Below is the Error message I get every time I install anything in the terminal . Its kinda stuck there for a while.
I tried no. of solutions from StackOverflow but nothing worked.
Before installing this package,
please download the Oracle JDK 11 .tar.gz file
with the same version as this package (version 11.0.4),
and place it in /var/cache/oracle-jdk11-installer-local,
E.g.:
sudo mkdir -p /var/cache/oracle-jdk11-installer-local
sudo cp jdk-11.0.4_linux-x64_bin.tar.gz /var/cache/oracle-jdk11-installer-local/
sha256sum mismatch jdk-11.0.4_linux-x64_bin.tar.gz
Oracle JDK 11 is NOT installed.
dpkg: error processing package oracle-java11-installer-local (--configure):
installed oracle-java11-installer-local package post-installation script subprocess returned error exit status 1
Errors were encountered while processing:
oracle-java11-installer-local
E: Sub-process /usr/bin/dpkg returned an error code (1)
Doesn't show up again.
Remove the package oracle-java11-installer-local. You can do this in following way:
sudo apt remove oracle-java11-installer-local
found this solution:
sudo rm /var/lib/dpkg/info/oracle-java11-installer-local.postinst
at this site.
You need to download the folder of the Oracle JDK 11 on here https://www.oracle.com/java/technologies/javase-jdk11-downloads.html
After download the tar.gz file. Move to your folder location then copy the file by using this command
sudo cp jdk-11.0.6_linux-x64_bin.tar.gz /var/cache/oracle-jdk11-installer-local/
don't forget to check your file name! After that repeat again by typing
sudo apt-get install oracle-java11-installer-local
and you can check your java version after that by typing
java -version
Hello,
I've had the same issue.
When you try to run sudo apt update && sudo apt upgrade it will automatically try to update the Java if a newer version is available. In my case let's say from 11.0.4 -> 11.0.5.
If you add the JDK from Oracle (after download) to /var/cache/oracle-jdk11-installer-local/ it should work.
You don't have to uninstall it...(I mean the oracle-jdk11-installer-local, it works just fine).
Please let me know if you still have this issue.
I had the same issue. My solution was to download jdk-11.0.5_linux-x64_bin.tar.gz and copied it to /var/cache/oracle-jdk11-installer-local.
In console shell, type:
sudo apt update && sudo apt upgrade
After a long search: this solved it for me.
The checksum made the issues for me. Try:
sudo rm /var/lib/dpkg/info/oracle-java11-installer-local.postinst -f
Navigating to the directory var/cache and doing "sudo rmdir oracle-jdk11-installer-local/" worked for me.
sudo rmdir oracle-jdk11-installer-local/
I have managed to resolve the issue by doing this:
modify /var/lib/dpkg/info/oracle-java11-installer-local.postinst
Change the checkSum. take from oracle website check sum for 11.0.15.1
3. change the version in 2 places
4. save and update apt
5. then sudo apt install oracle-java11-installer-local
this worked for me
I have Install php 7.3 and apache2 but when I try to start apache2 , I have this error :
service apache2 start
apache2: Syntax error on line 146 of /etc/apache2/apache2.conf: Syntax error on line 3 of /etc/apache2/mods-enabled/php7.3.load: Cannot load /usr/lib/apache2/modules/libphp7.3.so into server: /usr/lib/apache2/modules/libphp7.3.so: cannot open shared object file: No such file or directory
I really don't know how to resolve this problem, I have tried to remove and reinstall without success.
You're getting that error because the PHP 7.3 library for Apache is not installed.
sudo apt install -y libapache2-mod-php7.3
The above command should fix it.
It solved my problem:
sudo add-apt-repository ppa:ondrej/php
sudo apt-get update
sudo apt-get install php7.3
sudo apt-get install php7.3-cli php7.3-common php7.3-json php7.3-opcache php7.3-mysql php7.3-mbstring php7.3-zip php7.3-fpm php7.3-intl php7.3-simplexml
sudo service apache2 restart
For me the problem was that I did not install apache tools for php.
On arch linux:
yaourt -S php-apache
After that, module appeared in the folder.
The best way not to make a mistake is to follow guide: https://wiki.archlinux.org/title/Apache_HTTP_Server#PHP
I have an issue to install MSSQL on my Linux(Ubuntu 16.04) Server.
I have used the manual from Microsoft but I always fail on the same stage.
Actually, Docker is not an alternative due to Kernal issues.
After:
sudo apt-get install -y mssql-server
I'm supposed to do
sudo /opt/mssql/bin/mssql-conf setup.
This returns after answering all questions:
sqlservr[8383]: sqlservr: The configuration file '/var/opt/mssql/mssql.conf' failed to load (error: The INI file could not be opened. Errno [2] Filename [mssql.conf]).
I can access the config file and it seems to be usable by the script as well.
My Linux skills are not good enough to resolve this issue.
To answer some questions that were raised:
I tried sudo
cat the file returns the content as expected
Try running mssql server as root first (stop the service, run it as root, with /opt/mssql/bin/sqlservr) and see if it works that way. If it does, stop the mssql server and fix the ownership of the mssql dir with sudo chown -R mssql:mssql /var/opt/mssql). More info on this answer.
