Symfony2 cron job command in VPS - symfony

I have symfony2 project which I moved from a shared host to a VPS. I had a cron job command working in the shared host but I am unable to make it work in the VPS (WHM/cpanel CentOs 6).
The command I used in cpanel in the shared host was:
/usr/local/php-5.6.12/bin/php /home/a155r66t/public_html/mydomain.com/app/console api:import
In the VPS the route to the Symfony command is /home/mydomain.com/app/console api:import but I am unable to find which would be the route to the php in VPS. I tried these with no success:
/usr/local/php-5.5.29/bin/php /home/mydomain.com/app/console api:import
/usr/bin/php
/usr/local/bin/php
root php
Can you please indicate how could i find the correct route to the php? Or what should it be? Thanks.

Finally, with some good help I managed to sort it out. The correct sentence for the cron task in my VPS is: php /home/mydomain/app/console api:import

Debugging "Segmentation fault (core dumped)" for Flask App deployed on Apache with mod-wsgi-py3 (Ubuntu)

I created a Flask app that uses Beautiful Soup and Selenium to scrape and track Amazon product prices. The data was stored using CS50's version of SQLalchemy.
I then created an account to use Oracle's always free VM, with Ubuntu. I followed this excellent guide to the dot https://asdkazmi.medium.com/deploying-flask-app-with-wsgi-and-apache-server-on-ubuntu-20-04-396607e0e40f and set up Apache's conf file and the Wsgi file. I also added the network rules on Oracle's Virtual Cloud Network and to iptables, which I believe works fine.
Following this, the website still couldn't launch. Apache's error log showed a "PermissionError: [Errno 13] Permission denied: '/flask_session'". Based on this post Permission issue when writing file on webserver (flask, apache & wsgi) I changed the OS env to my env os.chdir('/home/ubuntu/flaskapp') and used chown to give rights
sudo chown -R ubuntu:www-data flaskapp
sudo chmod -R g+s flaskapp.
Now, my front page is accessible on http://129.150.38.171/ . However, upon any request to the server, Chrome displays "This page isn’t working 129.150.38.171 didn’t send any data." Apache's log shows a "segmentation fault (core dumped) python flask". Based on the sequence of my code, the error begins when I try to execute SQL, e.g. rows = usersdb.execute("SELECT * FROM users WHERE username = ?", request.form.get("username")).
I do not think that it is not my codes' error as it runs fine locally and the production server also worked when I set it up on Oracle VM using this guide https://docs.oracle.com/en-us/iaas/developer-tutorials/tutorials/flask-on-ubuntu/01oci-ubuntu-flask-summary.htm .
I've found this guide on debugging https://www.bustawin.com/debug-segmentation-faults-in-apache-from-mod_wsgi/ using gdb. But with source /etc/apache2/envvars
sudo -E gdb /usr/sbin/apache, it just tells me "No executable file specified".
Any ideas on what could be the error?

I have a VPS hosting with a domain redirecting to it.
I have LAMP stack for my main website using WordPress CMS.
Plus I am using Odoo as my back-end with python and PostgreSQL in a sub-domain.
Everything was working fine until I installed Certbot Let’s Encrypt to obtain an SSL certificate by following these tutorials
For My Wordpress i installed this plugin:
WP Encryption – One Click single / wildcard Free SSL certificate & force HTTPS
Which got me in a loop because it forced the https i will explain it later on
So when the plugin didn't work i searched for another way for the whole VPS with these tutorials:
How To Secure Apache with Let's Encrypt on Ubuntu 16.04
How To Secure Apache with Let's Encrypt on Ubuntu 18.04
After completing the second tutorial for ubuntu 18.04 i noticed that all my domain traffic is going to https and it got stuck in a loop saying same as i said above
"ERR_TOO_MANY_REDIRECTS which means Site redirected too many times"
and couldn't access the website front-end for the wordpress in the doamin.
Then when i applied
"Step 3 — Allowing HTTPS Through the Firewall"
my internet connection got interpreted and when i got back to the ssh session i found my self locked out of the server and did not find any way to get back in.
And when i tired to use the sub-domain that has Odoo on it i have got the same error
"ERR_TOO_MANY_REDIRECTS which means Site redirected too many times"
Until here i was hopeless and did't know what to do.
I contacted my VPS server provider and told him about what exactly happened. Then some how he managed to get me into the server again with a URL to the terminal i still couldn't access the server using ssh clients like putty.. so when i entered the server after he provided me with the URL first thing noticed is that he "rebooted the VPS" will get to this in a second.
So first thing i did was removing the wordpress plugin "WP Encryption" and update the wordpress site-url in wp_options table in mysql database because the plugin changed it from http to https so i changed it back and that solved the ERR_TOO_MANY_REDIRECTS for my wordpress website.
Then the second thing i did was disabling the ufw firewall that i enabled in the tutorial in Step 3 above.
I instantly got my connection to the server back using ssh client putty but what i have noticed again is the postgres service was inactive and went down with the reboot of the VPS. i tried to start the service but it didn't a gave me this error.
Failed to start postgresql.service: Unit postgresql.service is masked.
i searched for a solution and found these commands to unmask
sudo systemctl unmask postgresql
sudo systemctl enable postgresql
sudo systemctl restart postgresql
and then the service has started and everything sames OK when i run the status command
service postgresql status
the response is
● postgresql.service - LSB: PostgreSQL RDBMS server

Memory: 0B
CGroup: /system.slice/postgresql.service
but when i try to connect to postgres through the default port with odoo it says:
could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"
after many searches i made i found the posgres main cluster is also inactive or down i tried to start it with this command
pg_ctlcluster 11 main start
but i get this error
Job for postgresql#11-main.service failed because the service did not take the steps required by its unit configuration. See "systemctl status postgresql#11-main.service" and "journalctl -xe" for details.
and when i run the command as requested
systemctl status postgresql#11-main.service
i get this error

I guessed Let's Encrypt added an ssl configuration to the pg_hba.conf and postgres.conf like id did with apache so i searched for them and commented the "ssl on" lines and restarted postgres service along with the main cluster but nothing happened still the the same error which is
Error: Could not find pg_ctl executable for version 11
I know i shouldn't run pg_ctl directly under Ubuntu/Debian. I must use pg_ctlcluster instead, which is installed by postgresql-common. I saw the main page documentation. But when i run "sudo pg_ctlcluster 11 main reload" command i always get the above Error telling me that he could not find pg_ctl executable
I have searched a lot for this problem but nothing worked how can i solve the pg_ctl executable in version 11 ??
Ps:
I am using Ubuntu 19.10 (GNU/Linux 5.3.0-24-generic x86_64)
Odoo 11 with postgres 11 as the database odoo can't connect to postgres as i mentioned before
edit:
Unfortunately i can't do a restore or recover the server to fix postgres package because my last backup of the server was on 19/3 and today is 26/3 i have an important data between this period
Update 27/3/2020 4:06 AM
I compared my last server backup with the production server and found a lot of postgres files missing!! like int this path /usr/lib/postgres/11/ and /etc/postgres/11/ i think postgres some how got damaged and lost some files in the reboot of the server >>> but found the data files of the database located in /var/lib/postgres/11/ <<< Can i read them in my backup server ? i will try and let you know
So finally after a hours of digging
All PostgreSQL files where damaged and missing and i lost hope of repairing them i don't know what caused that but it has a relation with the accidental reboot of the server.
So i managed to find the main cluster data file for my important database information for the production server in this path
/var/lib/postgres/11/
and i took a backup from it by zipping the whole folder using this command
zip -r main.zip main/
then i did a full purge and reinstall for postgres usuing these commands from here
apt-get --purge remove postgresql\*
to remove everything PostgreSQL from your system. Just purging the postgres package isn't enough since it's just an empty meta-package.
Once all PostgreSQL packages have been removed, run:
rm -r /etc/postgresql/
rm -r /etc/postgresql-common/
rm -r /var/lib/postgresql/
userdel -r postgres
groupdel postgres
Then i installed postgres with this command to match odoo11
sudo apt-get install postgresql libpq-dev -y
then creating the ODOO PostgreSQL User
sudo su - postgres -c "createuser -s odoo" 2> /dev/null || true
Now everything is okay odoo should work fine but you still don't have any database
So to bring back the backup from the cluster folder we took earlier we need to move the zip file to the same directory we took it from which is
/var/lib/postgres/11/
but before that you should stop postgres service
sudo systemctl stop postgresql
and make sure it has stopped
sudo systemctl status postgresql
after that rename the main cluster that postgres uses right now because its empty and we don't need it because we are replacing it with our backed up cluster
mv /var/lib/postgres/11/main /var/lib/postgres/11/main_old
then move the zip file from where you backed it up to the postgres cluster folder with this command
mv /backups/main.zip /var/lib/postgres/11/
unzip the folder in the same path by using this command
unzip -a /var/lib/postgres/11/main.zip
after unzipping the folder give the ownership to your postgres user and group
chown -R postgres:postgres main
Then you are good to go. Start Postgres service
sudo systemctl start postgresql
sudo systemctl status postgresql
and make sure you also start the main cluster service
pg_ctlcluster 11 main start
if you stopped odoo make sure to start it also
service odoo-server start
Ps: I solved ERR_TOO_MANY_REDIRECTS for the odoo sub-domain by commenting ssl configurations in my odoo.config Apache2 virtual host that lets encrypt updated before and everything got back to where left it before installing lets encrypt.
I guess i will leave it here and won't use ssl in production again till i figure out how to use it in a test server .. thanks for your time i hope my question and answer helps someone in the future
Try adding 'pg_path' in your odoo configuration file.
Like: pg_path = /path/to/postgresql/binaries
Generally '/usr/lib/posrgresql/11/bin' is the binary directory.

Ubuntu Server Nginx Error after rebooting the server

An error occurred.
Sorry, the page you are looking for is currently unavailable.
Please try again later.
If you are the system administrator of this resource then you should check the error log for details.
Faithfully yours, nginx.
I rebooted the server just before happening this using sudo reboot now since it is an ubuntu server.
I checked this .I did not understand any of it unfortunately. Also I cant access any of the pages in the specific site of mine which is showing this error.
The error.log is empty on the location /var/log/nginx
error.log.1 has some logs which happens months ago. Same for access.log.1
I am not a network guy.
sudo service nginx status
sudo service nginx start
could be that for some reason nginx not started after reboot

What is the cause of the "502 Bad Gateway" after Ghost 1.8.7 update

I recently installed Ghost 1.8.4 and Nginx on my AWS ec2 Ubuntu 16.04 server. When I loaded my blog site, it correctly took me to the Ghost home page, from where I logged into Ghost admin. On the admin screen, there was a message to update.
I ran ghost update in putty
The update appeared to be successful, but when I returned to my blog site, I received the following error:
502 Bad Gateway
nginx/1.10.3 (Ubuntu)
Does anyone know a probably cause of this error and how to resolve?
I checked some posts, which suggested I should have turned Ghost off before the update. If this is true, is my ghost installation now corrupted?
I went to my ghost directory in /var/www/ghost and tried to run:
sudo service ghost start
but it returned:
Failed to start ghost.service: Unit ghost.service not found
and trying to stop, returns Unit ghost.service not loaded. Am I running the command from the correct location?
I've experienced 502 issues with ghost behind nginx several times over a few years of running it. I'm not sure if the cause of mine today is the same as yours, but what I observed was that after a restart ghost had changed its port number to one different than what its nginx config was listening on.
I followed these directions from https://web.archive.org/web/20200807095031/https://www.danwalker.com/running-ghost-on-a-5-digital-ocean-vps/ which resolved it for me:
See which port ghost is running on:
sudo netstat -plotn
Check that it matches the proxy_pass in the nginx config file in /etc/nginx/sites-enabled.
In my case the port in the nginx config had incremented to 2369 while the actual node process was running on 2368. Changing the proxy_pass port back to 2368 in my ghost blog's nginx config file resolved the issue for me.
I ran into the same problem after upgrading ghost.
Make sure the port number configured in your ghost's config file and the proxy_pass in your ghost site's nginx configuration files match.
Check the port number in
/var/www/ghost/config.production.json matches the proxy_pass port in the nginx config files.
/var/www/ghost/system/files/<yourDomainName>.<extension>.conf
/var/www/ghost/system/files/<yourDomainName>.<extension>-ssl.conf
In my case I had to change 2368 to 2369 in the nginx config files to fix the issue.
Make sure you restart your ghost and nginx after you make the changes.
# restart your ghost site
cd /var/www/ghost/
ghost restart
# restart nginx
sudo systemctl restart nginx
Hope this helps someone.
Apparently when I posted this issue it was due to a bug in the Ghost CLI that the ghost team were in the process of fixing.
They provided me with these instructions to run on my server:
systemctl stop ghost_www-blogwebsite-com
ghost update --force
The resulting output:
stopping Ghost [skipped]
Removing old Ghost versions [skipped]
This fixed the problem and updated to the correct version.

vagrant puphpet nginx 502 bad gateway error

I have installed nginx via puphpet and i am using laravel 4.1 with centos6.4. Laravael needs php apc module which i have included on puphpet congig.yaml file. after i do a vagrant up and I go to my site I get: connect() to unix:/var/run/php5-fpm.sock failed (111: Connection refused) while connecting to upstream error. I changed my nginx $fastcgi_pass = "/var/run/php5-fpm.sock" which didn't work. Then i did vagrant ssh and I ran service php-fpm restart after that it works. But I don't want to configure anything after i run vagrant up thats the purpose of puppet. Now my question is any way i can restart php-fpm when i do vagrant up or any other way to solve php apc problem. thanks in advance.
solution: after hours of researching i am able to solve the problem. I added this code:
exec { "restart php-fpm":
command => "service php-fpm restart"
}
in mainfeast.pp at the end of the php-fpm class. for me the line number is 485 or after the service.
I'd much rather you submit an issue via github # https://github.com/puphpet/puphpet/issues
That said, you can run any arbitrary code on $ vagrant up and $ vagrant provision via the exec-once and exec-always features mentioned on the frontpage.
That also said, this is a bug I'd love to fix, please submit a ticket!
