I installed Yosemite
Renamed MAMP to MAMP_old
Did a clean install of MAMP
Copied the db folder from old into the the new one
Now none of my databases appear in PHPMyAdmin
Inside the db/mysql folder I see the folder for my old databases, but there are no sql files. For example a Wordpress folder contains .frm files and db.opt files.
I tried doing this (using the link below), but I don't seem to have a mysql folder usr/local/
/usr/local/mysql/bin/mysqldump -u root -p[pass] [db] > [filename].sql
Can't access MySQL databases after upgrade to Mountain Lion (using MAMP)
What should I do to restore my old databases? I have very limited knowledge in this area.
Many thanks
I ran into this problem with upgrading to MAMP PRO 5 from 4. The following article proved invaluable:
https://appsolute.zendesk.com/hc/en-us/articles/215198946-I-upgraded-to-MAMP-PRO-5-and-I-am-missing-databases-
To quote:
Your old MySQL 5.6 data is in
/Library/application support/appsolute/MAMP PRO/db/mysql56_2018_xxxx
To be on the safe side, first make backups of your host data, and your
entire /Library/application support/appsolute/MAMP PRO/db/
To verify this is your old data, look inside of this mysql56_2018_xxx
folder, you should see subdirectories of all of your old databases in
this folder.
If you see missing databases in MAMP PRO 5, you can "reupgrade" your
old data by doing the following.
Quit MAMP PRO
Rename your mysql57 folder to mysql57_back
Make a copy of your mysql56_2018_xxxx folder, name it mysql57.
Start MAMP PRO, start your servers
Run Tools > Upgrade MySQL DB
Notes:
Instructions available online for MAMP (not MAMP PRO) may be misleading.
The above refers not to the /Library inside the package contents of the MAMP PRO app, but /Library from the root of your drive.
In my case the complete original databases were in the folder simply named mysql56. There were additional incomplete date-stamped folders suggestive of failures during the original DB update process.
Here is a link to an article which I think can help anyone in a similar situation:
How to Upgrade MAMP
So the basic idea is that you will need to copy your db files from the old MAMP folder to the new MAMP folder.
Another technique you could use would be do a mysqldump before upgrading, then import that dump file into the new version of MAMP.

Unfortunately I uninstalled Xampp in my windows machine, there are about 50 databases in /xamp/mysql/data folder. I have not taken backup script, but I have a copy of Xamp/mysql/data folder.How can I restore MySQL Databases using that Data Directory.
Thanks in Advance
I was find out solution
Install new xampp
Copy your old database folder from
xampp\mysql\data\databasefolder to Paste in your running xampp folder
C:\xampp\mysql\data
After that stop mysql and apache service then backup your running xampp files ib_logfile0,ib_logfile1 and ibdata1 and store in safe place
Then Copy same file (ib_logfile0,ib_logfile1 and ibdata1) from old
xampp\mysql\data\ and paste in your running xampp server C:\xampp\mysql\data\
Start mysql and apache service Open CMD Fire command
C:\xampp\mysql\bin>mysqldump -u dbusername -p dbpassword dbname>D:\exportdb.sql
stop mysql and apache service and restore your main ib_logfile0,ib_logfile1 and ibdata1 file (check Step 3)
after than again start service and open http://localhost/phpmyadmin/ and import database backup from D:\exportdb.sql
Now your backup is working :)
Install the same Server version again, Stop it , copy the datadir and Start the servrr
I experienced with my Mac, before selling to a friend simply copy the XAMPP folder only to my hard drive.
(NOT SUCCESS) Unfortunately, it was bringing trouble to me, because I tried the following steps:
- I install fresh XAMPP and copy the whole \httdocs and var\mysql to my new Mac, those db only with .frm and .ibd, NOT WORKING, I can't still access the tables inside PHPMyAdmin ...
- I tried to install the same xampp version and repeat the above steps, still NOT WORKING.
- Decided to go to bed.
(SUCCESS)
- This morning, I brought my backup disk and try with Windows 7.
- Install fresh latest XAMPP for Windows, c:\xampp
- I have one of website (folder) from my backup \httdocs and correspond database folder inside \var\mysql are READY in my windows 7, I just want to try with one website then try the rest because I have many projects inside httdocs\ and \var\mysql
- I copy the mention httdocs\ folder to windows c:\xampp\httdocs and copy the \var\mysql to c:\xampp\mysql\data
NOT LAST YET
I copy the ib_logfile0, ib_logfile1, ibdata1 from my backup file to windows xampp c:\xampp\mysql\data
I refresh the http://localhost/mywebsite
WOW WOW DONE ... it's working...
In my case I found pretty straight solution.
I had db files in wamp and ported to laragon
Stopped laragon instance, no apache/mysql was running.
I have simply copied db folder[dbname] "example /mysql/data/dbname" from wamp to laragon "/mysql/data/" folder
Than I started my laragon instance both apache/mysql.
I have checked in phpmyadmin, I can see same database was recovered and now part of current mysql database.
I just install a fresh copy of WAMP, and I want to import couple of databases from the old one to the new one, so I entered to the old mysql data directory C:\wamp-old\bin\mysql\mysql5.7.14\data, and copy the relevant databases there to the new data directory. But when I try to access the tables in phpmyadmin, I get a message saying that the tables aren't exists, but they do:
What am I missing?
You forgot to copy the ibdata file.
I did it successfully just now:
make a copy of wamp folder (wamp-old)
uninstall the wamp
install the new wamp (overwrite all the files if u were asked)
start the wamp
ck the localhost and phpmyadmin
copy your databases from the old-wamp only from C:\wamp-old\bin\mysql\mysql5.7.14\data and paste to the same location in new wamp
then copy and paste ibdata file from the above path and replace in new one.
You are done!
you can not restore databases like this way,
Please follow this steps to restore the databases from old to one,
Backup all the databases using phpmyadmin (Export Feature)
Install the fresh XAMPP
Restore the all the databases using phpmyadmin (Import Feature)
In my case the mySQL version of my old Wamp installation (5.7.26) was very different from the one in my new Wamp installation (8.0.21), so nothing from the solutions here worked for me.
I downloaded the old version of mysql from https://wampserver.aviatechno.net/#mysql_versions , installed it and replaced the hole ‘data’ folder with my old one.
Now from Wamp\MySQL\Version menu I can choose the old version and all my old databases are working fine.
You can leave that working version of mySQL or export the databases and import them to the new mySQL version.
Stop the Service (because it will complain for a file opened by another app) then Just copy and paste the ENTIRE (...\data) file from old installation folder backup to the new installation by overwirting the existing new installation file.
Finally, start the service.
I was on windows and using XAMPP(installed somewhere else than C:/ )
Now i have moved on to LINUX and installed LAMPP.
So, i have this XAMPP folder from windows and i copied the project files from htdocs and now i need the database which i didn't exported while i was on windows.
I tried to copy the phpmyadmin folder from the old XAMPP folder but couldn't get it to work.
So how can i access the previous OS phpmyadmin to use my existing databases -
using linux (MINT - rosa-cinnamon)
Thanks in Advance !
If you want to move databases between hosts - especially when there are differences in the MySQL daemon version, operating systems (-versions) or storage schema - you should create a MySQL dump at host A and import it on host B: http://dev.mysql.com/doc/refman/5.7/en/mysqldump-sql-format.html
If this is no option for you anymore, you can try to move the old MySQL data directory (Configured in my.ini on windows, somewhere in the xampp directory) to the location where the new MySQL daemon stores its data files (Normally configured at /etc/mysql.my.cnf). A few more hints on this:
Ensure to modify the file permissions on the data files at the new location that the MySQL daemon can work with them.
On Windows, MySQL table names are case insensitive. On Linux they are case sensitive. Keep that in mind, if your application complains about missing tables.
And of course: Test this with backups only!
I had to format my Mac as updating OSX Crashed. I had the backup of the XAMPP folder on my disk. Is there a way I can copy some files to the newly installed XAMPP folder and get all databases back?
Do I make any sense?
I tried copying all folder but XAMPP failed to start throwing Requires Admin Privileges
Note: I have no recent .sql backup of the databases.
I once had the same problem. It's not that complicated.
Just copy the folders of database to XAMPP/var/mysql/
That's all.
I was working with XAMPP 1.8.3-3 on OS X Mavericks. After upgrading to Yosemite Mysql server stopped working. And an upgrade to XAMPP 1.8.3-5 fixed the problem and mysql server starts working.
Now the entire database list is showing on phpmyadmin, but no access to the tables. Its showing “#1146 - Table ‘DB_NAME.TABLE_NAME’ doesn’t exist”.
Unfortunately I don't have any DB backup!
I have the entire XAMPP folder backup. So how I can able to retrieve the mysql tables?
just type /Applications/XAMPP/xamppfiles/bin/mysql.server start
in terminal then start xampp
you can restore if you have all the mysql folders from XAMPP folder. (check /XAMPP/xamppfiles/var/mysql in backup)
if you have var/mysql folder, open and look for database names you had earlier.
there is a separate folder for each database you had earlier. open the folder and it will contain lots of files with table names.
if your old table engine is InnoDB you will see 2 files. with .frm and .ibd extensions.
or if you had MyISM it will contain three file per table which has .frm, .MYD and .MYI extensions.
after you verify you have all the required files in backup, you can start restoring them.
stop mysql
copy required database folder completely and paste it to currently installed folder. (/Applications/XAMPP/xamppfiles/var/mysql/)
start mysql
to restore web files, open htdocs folder in backup and copy required site folder to currentely xampp installed htdocs folder.
This solution worked for me. Good Luck !
Do a clean install. See my answer for my own question. xampp mysql server not starting. The bad part is that I'm not sure if it will save your database the way I explained. What you might try is going to xampp > xamppfiles > var > mysql > 'your database name' and making a copy of the database folder on your desktop and moving it back once you reinstall it. I tried and I think it might have worked had I changed the file permissions. You can also try experimenting to see if it preserves the database if you do this. I would do some serious testing if you really want to save your database before doing this.
