I have an old phpMyAdmin installation (contains my training and jobs data). I want to update it to the latest version and I want to keep my data safe while updating it. Is there any way to do it by running some commands on the terminal? Is my data erased if I uninstall phpMyAdmin?
Here is how to upgrade/downgrade on Ubuntu.
Note: The following instruction only works if you previously (and correctly) installed phpMyAdmin with the command line and use APACHE as a web server.
I suppose that you already have a working phpMyAdmin, but the version isn't the one you want. For instance, Ubuntu is shipping the 4.6.x version which doesn't work properly with PHP 7.2.
Check the version you want on:
https://www.phpmyadmin.net/files/
On your server
cd /usr/share/
rm -rf phpmyadmin
then adapt this line with the correct version number
wget https://files.phpmyadmin.net/phpMyAdmin/4.8.0/phpMyAdmin-4.8.0-all-languages.zip
unzip phpMyAdmin-4.8.0-all-languages.zip
rm phpMyAdmin-4.8.0-all-languages.zip
mv phpMyAdmin-4.8.0-all-languages phpmyadmin
Note: If unzip don't work, install it with: sudo apt-get install unzip
Check permissions
Now you should be good.
The owner of /usr/share/phpmyadmin should be root:root on a default installation. This should be fine but if you face some permissions issues, you can try to let Apache be the owner:
# only if you have permissions issues
chown -R www-data:www-data /usr/share/phpmyadmin
chmod -R 755 /usr/share/phpmyadmin
You can also restart Apache
sudo service apache2 reload
Troubleshooting
Note: Depending on your PHP version, you may need to install additional libraries.
For example, to resolve the error about missing mysqli and mysql extensions (update the command to reflect your PHP version):
sudo apt-get install php5.6-mysql
phpmyadmin is mysql client, so it will not affect your database if you uninstall phpmyadmin.
I update phpmyadmin by using terminal commands:
First you have to add repository to get phpmyadmin :
sudo add-apt-repository ppa:nijel/phpmyadmin;
and then update it to get the latest version of software in repositories :
sudo apt-get update;
after that, you can get it (install, you need to uninstall the older version first if you have) :
sudo apt-get install phpmyadmin;
Oh, make sure you are connected to the internet
Using ubuntu? i think it will be better if you ask it in ubuntu forum.
may it helps
------ UPDATE -------
If you find the phpmyadmin version you get from ppa is not the latest one, you can find the latest version here and install it manually (not from repo).
Downloaded phpmyadmin can be installed in /var/www/html/ or in your working directory (public_html or something you've defined). Just extract the zip and move extracted folder to /var/www/html/. And don't forget to change the permission of the phpmyadmin folder to 777(it may not safe, but works fine).
Here is the how:
extract downloaded file
unzip phpMyAdmin-4.6.6-all-languages.zip
move to /var/www/html/, you might need sudo.
if you're not sudoer, move it into your working directory (e.g. public_html), and rename the folder to 'phpmyadmin'
sudo mv phpMyAdmin-4.6.6-all-languages /var/www/html/phpmyadmin
change the permission
sudo chmod 777 -R /var/www/html/phpmyadmin
and then you can access phpmyadmin via http://localhost/phpmyadmin.
If you put the phpmyadmin in public_html, you might want to create a symlink into it from /var/www/html, so you can access phpmyadmin as usual.
phpMyAdmin is only client for MySQL database, it doesn't contain your data. It's all saved in database, so nothing will be deleted even if you delete phpMyAdmin.
To update phpMyAdmin from repository you can follow steps from this thread.
1- check your phpmyadmin version from GUI.
2- Download Latest version of phpMyAdmin HERE
Use the below command to download the latest version of phpMyAdmin into /opt or /usr/src directory
# wget https://files.phpmyadmin.net/phpMyAdmin/4.8.3/phpMyAdmin-4.8.3-all-languages.zip
Notes to install unzip package: apt-get install unzip
# unzip phpMyAdmin-4.8.3-all-languages.zip
3- Find phpMyAdmin Installation Directory
Use the below command to search the phpMyAdmin Installation Directory on your system
# /usr/share/phpMyAdmin
4- Remove/Delete phpMyAdmin content
/usr/share/phpmyadmin is correct phpMyAdmin installation directory, Just Delete/Remove everything from that directory
# cd /usr/share/phpMyAdmin/
# rm -Rf *
5- Move/Copy New phpMyAdmin content
Use the below command to copy all the new phpMyAdmin content to /usr/share/phpmyadmin.
# cd /opt/phpMyAdmin-4.8.3-all-languages
# mv * /usr/share/phpMyAdmin/
6- Restart Apache, MySQL or MariaDB service.
Start/Restart the service in SysVinit Systeme
# service restart httpd
# service restart mysql
Start/Restart the service in Systemd Systeme
# systemctl restart httpd.service
# systemctl restart mariadb.service
7- Now Check New version of phpMyAdmin
Navigate your browser to http://localhost/phpmyadmin, Now you are using latest version 4.8.3 of phpMyAdmin.
Reference
sudo su
cd /usr/share/
rm -rf phpmyadmin
wget https://files.phpmyadmin.net/phpMyAdmin/4.8.4/phpMyAdmin-4.8.4-all-languages.zip
unzip phpMyAdmin-4.8.4-all-languages.zip
mv phpMyAdmin-4.8.4-all-languages phpmyadmin
chown -R www-data:www-data /usr/share/phpmyadmin
chmod -R 755 /usr/share/phpmyadmin
sudo service apache2 reload

Operation system: ubuntu 16.04
Runs in a VWWare Player
I installed Lamp with apache2, php, mysql and it works just fine.
then I installed phpmyadmin
sudo apt-get install phpmyadmin
This installs a lot, but if I open the browser with localhost/phpmyadmin I get the 404 Error: Page not found.
I searched for other ways: I was told to just copy the phpmyadmin.***.tar file to the document_root folder. This works, but I don't have access to the Database. I get the User/PWD Dialog but I haven't set anything, so I don't know the password
I would like to get some help on the "sudo install phpmyadmin" way, which seems to me to be the right one.
Regards Martin
I read about some changes up from ubuntu 13
The following did the trick:
sudo ln -s /etc/phpmyadmin/apache.conf /etc/apache2/conf-available/phpmyadmin.conf
sudo a2enconf phpmyadmin
sudo service apache2 restart
After that I could open localhost/phpmyadmin (But I forgot the password)
So I removed phpmyadmin
sudo apt-get remove --purge phpmyadmin
and simply reinstalled it:
sudo apt-get install phpmyadmin
User name is phpmyadmin and the password has to be set during the installation
I would highly suggest installing this manually so it's up to date and as secure as possible.
cd to webroot
IE: cd /var/www/html
wget https://files.phpmyadmin.net/phpMyAdmin/4.7.7/phpMyAdmin-4.7.7-all-languages.zip && unzip phpMyAdmin-4.7.7-all-languages.zip
Make sure unzip + wget are installed.
apt-get install wget unzip
I also suggest renaming the phpmyadmin dir.
mv phpMyAdmin-4.7.7-all-languages random-name-here
have you tried root with no password? Sorry I'm not allowed to add this as comment.
I just finished going through the MedaWiki installation steps, and have moved LocalSettings.php to the root directory of the wiki, but the wiki fails to load. Instead, when I go to the wiki index page, the request hangs and does nothing.
attempted /var/www recursive permissions:
777 nobody:nogroup
777 www-data:www-data
777 sshUser:sshUser
Server settings:
Ubuntu 15.04 Lighttpd php5-fpm php5-cgi mysql-server
Other websites load, it's just MediaWiki that fails after exporting LocalSettings.php to the MediaWiki root directory.
I got it to work. What I did was the follow the steps on https://www.raspberrypi.org/forums/viewtopic.php?t=9566 to apt-get install more php files:
sudo apt-get install mysql-client phpmyadmin php5-cgi php5-mysql php5-curl php5-gd php5-idn php-pear php5-imagick php5-imap php5-mcrypt php5-memcache php5-mhash php5-ming php5-pspell php5-recode php5-snmp php5-sqlite php5-tidy php5-xmlrpc php5-xsl php5-fpm php5-cgi php5-cli php5-common php5-suhosin
After doing that, and changing the permissions to the wiki root directory to 777, I deleted the old LocalSettings.php and restarted the installation to create a new one. It worked with the new LocalSettings.php.
I'm on Kubuntu 12.04, and after installing mysql via an apt-get (mysql ver: 5.5.35), i'm trying to start mysql service, but I got this error:
sudo service mysql start
start: Job failed to start
So I googled this problem, it says i have to go to the /var/log/mysql/error.log
But my error.log file is empty :(
Then I checked the permissions
:
drwxr-s--- 2 mysql adm 4096 Apr 7 11:21 mysql
-rw-r----- 1 mysql adm 0 Apr 7 11:21 error.log
So I don't know what to do... Why this error ? Why is the error file empty ?
First make a backup of your /var/lib/mysql/ directory just to be safe.
sudo mkdir /home/<your username>/mysql/
cd /var/lib/mysql/
sudo cp * /home/<your username>/mysql/ -R
Next purge MySQL (this will remove php5-mysql and phpmyadmin as well as a number of other libraries so be prepared to re-install some items after this.
sudo apt-get purge mysql-server-5.1 mysql-common
Remove the folder /etc/mysql/ and it's contents
sudo rm /etc/mysql/ -R
Next check that your old database files are still in /var/lib/mysql/ if they are not then copy them back in to the folder then chown root:root
(only run these if the files are no longer there)
sudo mkdir /var/lib/mysql/
sudo chown root:root /var/lib/mysql/ -R
cd ~/mysql/
sudo cp * /var/lib/mysql/ -R
Next install mysql server
sudo apt-get install mysql-server
Finally re-install any missing packages like phpmyadmin and php5-mysql.
My problem was running out of memory. Digital ocean has great instruction for adding swap memory for Ubuntu: https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-14-04
This solved the issue and enabled me to restart the Mysql that otherwise would not start.
Reinstallation will works because it will reset all the value to default. It is better to find what the real culprits (my.cnf editing mistake does happens, e.g. bad/outdated parameter suggestion during mysql tuning.)
Here is the mysql diagnosis if you suspect some value is wrong inside my.cnf : Run the mysqld to show you the results.
sudo -u mysql mysqld
Afterwards, fix all the my.cnf key error that pop out from the screen until mysqld startup successfully.
Then restart it using
sudo service mysql restart
In my case, it simply because the disk is full.
Just clear some disk space and restart and everything is fine.
In most cases, just purging the mysql-server package and re-installing it will do the job.
Run,
sudo apt-get purge mysql-server-5.1 mysql-common
followed by
sudo apt-get install mysql-server
This line did solve the issue in my case,
sudo apt clean
In my case, i do:
sudo nano /etc/mysql/my.cnf
search for bind names and IPs
remove the specific, and let only localhost 127.0.0.1 and the hostname
Check the file permissions, if edited
Fail:
$ sudo chmod 776 /etc/mysql/my.cnf
$ sudo service mysql restart
mysql stop/waiting
start: Job failed to start
Ok:
$ sudo chmod 774 /etc/mysql/my.cnf
$ sudo service mysql restart
stop: Unknown instance:
mysql start/running, process 9564
To help others who do not have a full disk to troubleshoot this problem, first inspect your error log (for me the path is given in my /etc/mysql/my.cnf file):
tail /var/log/mysql/error.log
My problem turned out to be a new IP address allocated after some network router reconfiguration, so I needed to change the bind-address variable.
In my case the problem was the /var/log disk full (check with df -h)
Just deleted some log files and mysql started, no big deal!
The given solution requires enough free HDD, the actual problem was the HDD memory shortage. So If you don't have an alternative server or free disk space, you need some other alternative.
I faced this error with my production server (Linode VPS) when I was running a bulk download into MySQL. Its not a proper solution but VERY QUICK FIX, which we often need in production to bring things UP FAST.
Resize our VPS Server to higher Hard Disk size
Start MySQL, it works.
Login to your MySQL instance and make appropriate adjustments that caused this error (e.g. remove some records, table, or take DB backup to your local machine that are not required at production, etc. After all you know, what caused this issue.)
Downgrade your VPS Server to previous package you was already using
In my case:
restart server
restart mysql
create .socket in directory
I had the same problem. But i discover that my hd is full.
$ sudo cat /var/log/upstart/mysql.log
/proc/self/fd/9: ERROR: The partition with /var/lib/mysql is too full!
So, I run
$ df -h
And I got the message
/dev/xvda1 7.8G 7.4G 0 100% /
Then I found out which folder was full by running the following command on the terminal
$ cd /var/www
$ for i in *; do echo $i; find $i |wc -l; done
This give me the number of files on each folder on /var/www. I logged into the folder with most files, and deleted some backup files, and i continued deleting useless files and cache files.
then I run $ sudo /etc/init.d/mysql start and it work again
I test Drupal websites on my site locally on Mac using Phpmyadmin.
I recently had to to do a clean reinstall of my Mac. I have a full back up of my hardrive, but I'm not sure where to locate the databases in the back up and how to restore them.
Where does Phpmyadmin store the databases?
/usr/local/mysql/data
try it here
phpMyAdmin does not write any database files. It is a php client application which accesses a MySQL server.
On OSX the MySQL server creates its data files in /usr/local/mysql/data as far as I know.
1. Stop your MySQL server
sudo /usr/local/bin/mysql.server stop
2. Remove new data files
sudo mv /usr/local/mysql/data /usr/local/mysql/data.new
3. Copy old data files from your backup and fix prrmissions
sudo chown -R _mysql:wheel /usr/local/mysql/data
4. Start your server again
sudo /usr/local/bin/mysql.server start
5. Check and optimize databases
sudo /usr/local/mysql/bin/mysqlcheck --all-databases
Now phpMyAdmin will show all old databases
Is it possible to upgrade the MAMP MySQL library to 5.6 ?
Or I'll need to install MySQL natively (Lion) ?
If someone could point me in the right direction...
Thanks!
The latest MAMP has MySQL 5.5.9. Given the occasional wonkiness of MAMP and general lack of support, I'd be hesitant to mess about with it internally to upgrade it.
However, there's nothing wrong with disabling the MySQL that comes with it, installing 5.6 separately, then pointing it at the MAMP MySQL data files. You'll need to remember to run the upgrade script that comes with MySQL, so probably best to take a copy of the MAMP data first and move it to the data folder of the new MySQL install.
The only reason to use MAMP in the first place is that messing about with the built in copy of Apache can make file sharing stop working, so it's easier to use MAMP instead on a different port, but this doesn't apply to MySQL so you should be OK.
It is possible. I have it running. Install MySQL
http://dev.mysql.com/downloads/mysql/
Download the Mac version
Then change your mysql.sock in MAMP to the new one
mv /Applications/MAMP/tmp/mysql/mysql.sock /Applications/MAMP/tmp/mysql/mysql.sock.back
ln -s /var/mysql/mysql.sock /Applications/MAMP/tmp/mysql/mysql.sock
Restart MAMP
Found a solution on gist and modified it a bit:
#!/bin/sh
wget http://cdn.mysql.com/Downloads/MySQL-5.6/mysql-5.6.22-osx10.9-x86_64.tar.gz
tar xfvz mysql-5.6*
rm mysql-5.6.22-osx10.9-x86_64.tar.gz
echo "stopping mamp"
sudo /Applications/MAMP/bin/stop.sh
sudo killall httpd mysqld
echo "creating backup"
sudo rsync -a /Applications/MAMP ~/Desktop/MAMP-Backup
echo "copy bin"
sudo rsync -av mysql-5.6.*/bin/* /Applications/MAMP/Library/bin/ --exclude=mysqld_multi --exclude=mysqld_safe
echo "copy share"

If everything worked, you have to delete the mySQL backup on your desktop. You can check the current mySQL-Version by executing the following command on your local server:
SHOW VARIABLES LIKE "%version%"
Download the official script by MAMP to update your MySQL to 5.6.12
http://blog-en.mamp.info/2015/07/how-to-use-mysql-5-6-with-mamp-and-mamp.html
For those of you who absolutely require MySQL 5.6 to be part of their development environment - maybe you are a Magento developer - we have released a shell script that updates the MySQL component of MAMP and MAMP PRO to v5.6. The script requires at least MAMP and MAMP PRO 3.3, older versions are untested.
Since MAMP 4.x is released, just use that version / upgrade your existing MAMP installation. MySQL 5.6 is already included.
