I'm using password-less key based login with sudo to execute remote commands. I have figured out that I have to spawn a new shell to execute commands that write to root areas of the remote file system. But, I would like a clear explanation of exactly why this is the case?
This fails:
sudo -u joe ssh example.com "sudo echo test > /root/echo_test"
with:
bash: /root/echo_test: Permission denied
This works fine:
sudo -u joe ssh example.com "sudo bash -c 'echo test > /root/echo_test'"
It's the same reason that a local sudo echo test >/root/echo_test will fail (if you are not root) -- the redirection is done by the shell (not the sudo or echo command) which is running as the normal user. sudo only runs the echo command as root.
With sudo -u joe ssh example.com "sudo echo test > /root/echo_test", the remote shell is running as a normal user (probably joe) and does not have permission to write to the file. Using an extra bash invokation works, because sudo then runs bash as root (rather than echo), and that bash can open the file and do the redirect.
I have hosted one docker with PHP in a shared server of our office environments. Previously it was working fine without any issue. All the users were able to access the site via port forwarding to 8080. Here is my docker file details -

Suddenly one of my friend added another docker with same port 8080 in the same server. After that my docker got stopped. with below error -
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 172.18.0.3. Set the 'ServerName' directive globally to suppress this message
httpd (pid 1) already running
After several hours of googling and after trying lots of commands, I found that its easy to remove the entire container as well as images from the server. Hence I removed all containers with docker rm followed by image deletion with docker rmi. Again i have recreated the docker image on my local system (its working here) and transferred to server. Again I tried to run the docker. But faced same issue again.
Unable to find out the cause & solution. Need some help.
first remove ENTRYPOINT from your Dockerfile and just use:
CMD [ "/usr/sbin/httpd", "-X" ]
the warning regarding AH00558 is comming from your configuration and it i complaining about you do not use www.test.com you can ignore that for now and apache will still working. if you want to read more see this
after installing lets encrypt ssl certificate I got error in my apache server.
AH00526: Syntax error on line 46 of
/opt/bitnami/apache2/conf/bitnami/bitnami.conf: SSLCertificateFile:
file '/opt/bitnami/apache2/conf/server.crt' does not exist or is empty
apache config test fails, aborting.
Kindly help me.
Bitnami Engineer here.
The link to the section about how to generate and configure a Let's Encrypt certificate in our solutions is this one
https://docs.bitnami.com/general/how-to/generate-install-lets-encrypt-ssl/
As the guide mentions, you need to:
1.Generate the certificates with the Lego tool
sudo /opt/bitnami/ctlscript.sh stop
sudo lego --email="EMAIL-ADDRESS" --domains="DOMAIN" --path="/etc/lego" run
2.Link the certificates with the files that Apache uses
sudo mv /opt/bitnami/apache2/conf/server.crt /opt/bitnami/apache2/conf/server.crt.old
sudo mv /opt/bitnami/apache2/conf/server.key /opt/bitnami/apache2/conf/server.key.old
sudo mv /opt/bitnami/apache2/conf/server.csr /opt/bitnami/apache2/conf/server.csr.old
sudo ln -fs /etc/lego/certificates/DOMAIN.key /opt/bitnami/apache2/conf/server.key
sudo ln -fs /etc/lego/certificates/DOMAIN.crt /opt/bitnami/apache2/conf/server.crt
sudo chown root:root /opt/bitnami/apache2/conf/server*
sudo chmod 600 /opt/bitnami/apache2/conf/server*
It's important that you change DOMAIN with the domain you set when running this command. If not, you will point to a non-existing file and Apache will fail.
You can review that it points to the proper file by running this command. This is what you need to review now.
ls -la /opt/bitnami/apache2/conf/server*
In case it the file that it points to doesn't exist, please run the commands of the step 2 again after ensuring that the certificate files exist
sudo ls -la /etc/lego/certificates
After that, restart the services again
sudo /opt/bitnami/ctlscript.sh start
Setting up a development environment with Ubuntu 14.04 running in VirtualBox, following this guide: http://klau.si/dev
After installing phpmyadmin, it seems I should be able to access it at http://localhost/phpmyadmin but apache returns a Not Found error. Did this guide leave out a configuration step somewhere? I have already tried restarting the apache service.
There is no phpmyadmin.conf file in apache2/sites-enabled or apache2/sites-available, is this required?
If so, where can I find these files?
using 127.0.0.1 instead of localhost returns the same error. The default apache page at http://localhost works just fine.
the console in the browser shows nothing of value, simply Not Found.
I have also tried rerunning the install script with dpkg-reconfigure -plow phpmyadmin
This issue was resolved thanks to this guide: https://help.ubuntu.com/community/ApacheMySQLPHP#Troubleshooting_Phpmyadmin_.26_mysql-workbench by adding
Include /etc/phpmyadmin/apache.conf
...to the /etc/apache2/apache2.conf file and restarting the service.
Try this
sudo ln -s /etc/phpmyadmin/apache.conf /etc/apache2/conf-available/phpmyadmin.conf
sudo a2enconf phpmyadmin.conf
sudo systemctl restart apache2
sudo dpkg-reconfigure -plow phpmyadmin
Select No when asked to reconfigure the database. Then when asked to choose apache2, make sure to hit space while [ ] apache2 is highlighted. An asterisk should appear between the brackets. Then hit Enter. Phpmyadmin should reconfigure and now http://localhost/phpmyadmin should work. for further detail https://www.howtoforge.com/installing-apache2-with-php5-and-mysql-support-on-ubuntu-13.04-lamp
The easiest way to do in ubuntu (I tested in ubuntu-20.04):
Step 1. Open the file:
sudo nano /etc/apache2/apache2.conf
Step 2: Add the following line at the end of file:
Include /etc/phpmyadmin/apache.conf
Step 3: Restart apache2:
sudo systemctl restart apache2.service
Create a link in /var/www like this:
sudo ln -s /usr/share/phpmyadmin /var/www/
Note: since 14.04 you may want to use /var/www/html/ instead of /var/www/
If that's not working for you, you need to include PHPMyAdmin inside apache configuration.
Open apache.conf using your favorite editor, mine is nano :)
sudo nano /etc/apache2/apache2.conf
Then add the following line:
Include /etc/phpmyadmin/apache.conf
For Ubuntu 15.04 and 16.04
sudo ln -s /etc/phpmyadmin/apache.conf /etc/apache2/conf-available/phpmyadmin.conf
sudo a2enconf phpmyadmin.conf
sudo service apache2 reload
Finally I got the solution
sudo ln -s /etc/phpmyadmin/apache.conf /etc/apache2/conf-available/phpmyadmin.conf
sudo a2enconf phpmyadmin
sudo service apache2 reload

Create a link in /var/www/html like this to fix the error:
sudo ln -s /usr/share/phpmyadmin /var/www/html
For anyone still running into issues with this- check that you're actually using apache! I knocked my head against this for 20 minutes or so before I remembered...I use NginX on this server...=). #john-smith, this one's for you buddy.
To get it working on nginx, all you should have to do is create a sim link and restart php:
sudo ln -s /usr/share/phpmyadmin /var/www/html
Note that for you, it may be /var/www/ and not /var/www/html, depending on your dir structure.
sudo ln -s /etc/phpmyadmin/apache.conf /etc/apache2/conf-available/phpmyadmin.conf
sudo ln -s /usr/share/phpmyadmin /var/www/html/phpmyadmin
sudo service apache2 restart
Run above commands issue will be resolved.
Run the following command in terminal:
sudo ln -s /usr/share/phpmyadmin /var/www/html/
It seems like sometime during the second half of 2018 many php packages such as php-mysql and phpmyadmin were removed or changed. I faced that same problem too. So you'll have to download it from another source or find out the new packages
You will need to configure your apache2.conf to make phpMyAdmin works.
sudo nano /etc/apache2/apache2.conf
Then add the following line to the end of the file.
Include /etc/phpmyadmin/apache.conf
Then restart apache
sudo service apache2 restart
I had the same issue where these fixes didn't work.
I'm on Ubuntu 20.04 using hestiaCP with Nginx.
Today after adding
Include /etc/phpmyadmin/apache.conf
into both Apache and Nginx, Nginx failed to restart. It was having an issue with "proxy_buffers" value.
Yesterday I had to modify the Nginx config to add and increase these values so Magento 2.4 would run. Today I altered "proxy_buffers" again
proxy_buffers 3 64k;
proxy_buffer_size 128k;
proxy_busy_buffers_size 128k;
After the second alteration and the removal of "Include /etc/phpmyadmin/apache.conf" from both Apache and Nginx, Magento 2.4 and PHPMyAdmin are working as expected.
I didn't try Rashmi Jain's symlink answer. It seems like it would work. But if it doesn't work for you, perhaps try this.
I just created the file `/etc/apache2/conf-available/phpmyadmin.conf' and added this line to it:
Include /etc/phpmyadmin/apache.conf
(rather than putting it into /etc/apache2/apache2.conf as in Anonymous Man's answer)
Then:
sudo a2enconf phpmyadmin
sudo systemctl reload apache2
I had the same problem after installing mysql, apache2, php and finally phpmyadmin after each other. In my case it was solved by restarting apache2 (no need to update any configuration file):
sudo systemctl restart apache2
#John smith, I was facing the same issue of not being able to access phpmyadmin for 3 days, I found the solution.
-- Get xampp, check this tutorial https://youtu.be/VHfij95yOpo
-- Run this command before starting xampp app
sudo /etc/init.d/apache2 stop
sudo service mysql stop
That's it, it worked for me
first go to the location of phpmyadmin via terminal then type this
code php -S localhost:8001
First check PhpMyAdmin is install or not. If it is installed then search PhpMyadmin folder. After search cut and paste that folder in location Computer->var->www->html->paste folder. Open browser and type localhost/phpMyAdmin and login using username and password.
If you are having this problem in 2019, go to your 000-default.conf file, by typing this subl /etc/apache2/sites-enabled/000-default.conf (in your terminal to open the file in sublime editor)
When the file loads, locate "The ServerName directive sets the request scheme" and place this "Include /etc/phpmyadmin/apache.conf" on top .
Then restart your apache with the command...service apache2 restart That will certainly fix the issue. Hope it helps!
I searched google for an answer for this question but I haven't got the exact answer. I want to install glassfish in Suse linux server. I downloaded glassfish3.sh from oracle but when I run that script, the folder where glassfish is installed is /home/$user/glassfish and I want to change it.
Does someone know how to change the path of glassfish 3.1.1 in ubuntu server? (only terminal)
Thanks!
You downloaded the .sh file. This will always install GlassFish into the user's home directory. In order to install it into different directory it is a little bit more work to do.
Download and unzip the file. For e.g. you want glassfish to be in: /opt/glassfish:
wget http://download.java.net/glassfish/3.1.1/release/glassfish-3.1.1.zip
sudo unzip glassfish-3.1.1.zip -d /opt
That is it. Glassfish is installed and you can start and use it. But don't forget that you did not configure any automatic start up scripts to glassfish start up automatically.
In order to do that, run this command in your shell:
sudo vim /etc/init.d/glassfish
Paste this content: (first make change that is appropriate to you)
#!/bin/bash
GLASSFISH_HOME=/opt/glassfish3
case "$1" in
start)
${GLASSFISH_HOME}/bin/asadmin start-domain domain1
;;
stop)
${GLASSFISH_HOME}/bin/asadmin stop-domain domain1
;;
restart)
${GLASSFISH_HOME}/bin/asadmin stop-domain domain1
${GLASSFISH_HOME}/bin/asadmin start-domain domain1
;;
*)
echo "usage: $0 {start|stop|restart}"
;;
esac
exit 0
The last thing is to make the script executable by running these commands:
sudo chmod 755 /etc/init.d/glassfish
sudo update-rc.d /etc/init.d/glassfish defaults
Now you can start, stop and restart glassfish like this:
sudo /etc/init.d/glassfish start
sudo /etc/init.d/glassfish stop
sudo /etc/init.d/glassfish restart
