I'm trying to import sql file into my database with this command in cmd:
mysql -u root -p social-media-db < socialmediaexaminer_dev_2017-07-15T18-41-51_UTC_database.sql
And yes i've google it before, readed all of the existing documentation why this happens and nothing helps me. It said
ERROR 2006 (HY000) at line 2759: MySQL server has gone away

The file i'm trying to import is 1.4GB.
It is unlikely your equipment can support this request in your .ini --
max_allowed_packet=99999999M
That would be about 99,999,999,000,000 bytes of memory. 99 Terabytes?
Reduce it to something like 100M and let us know if this works for you.
When the following command is executed it shows ton of vairables.
mysql>show variables;
But, what is the location of file which loads. In /usr/local/mysql/my.cnf shows almost a empty file and is listed below.
Where and how can I modify the parameters like port?

You can trace the location of your config file through the following command
>> mysql --verbose --help | grep -A 1 'Default options'
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/local/mysql/etc/my.cnf ~/.my.cnf
I usually don't ask questions on this, but I'm beating my head against the wall with this one. I am trying to setup WAMP to work with Dropbox. I've used both these tutorials (http://mymediamagnet.com/how-to-setup-wamp-with-dropbox/ and http://abhisheksachan.blogspot.com/2012/08/web-development-environment-made-easy.html) as they both tell me the same thing.
The httpd.conf settings that you make in Apache have worked great. All my files in my new www folder are respected and are shared across multiple computers in Dropbox. But my setup to make the database files be stored in Dropbox don't seem to be respected.
I have edited the my.ini file to contain the right Dropbox mysql folder in datadir. I have copied everything from here: C:\wamp\bin\mysql\mysql5.6.17\data to this new Dropbox mysql folder. But everytime I open phpmyadmin, and add or remove databases, it does it in the old wamp folder: C:\wamp\bin\mysql\mysql5.6.17\data.
I find this my.ini file here: C:\wamp\bin\mysql\mysql5.6.17 so I know it's the one that WAMP should be using. I've tried troubleshooting by deleting it completely, screwing up all the data in the file, but mysql just keeps on working and looking at the old database folder.
So my only thought was that this configuration file is not being respected. There are some instructions at the top that I don't completely understand about this being an example file but everywhere I look says that this is what wamp looks at. So now I'm lost and don't why it's not working.
Please help. Here is my entire my.ini file as I'm sure the key is somewhere in there.

There was a little bug with the 64bit WAMPServer in version 2.5
Change this in your 64bit my.ini
From
# The MySQL server
[wampmysqld]
To
# The MySQL server
[wampmysqld64]
This section header must match the service name that MySQL server runs under, and on the 64bit WAMPServer it was changed to wampmysqld64, but this section header was forgotten about.
NOTE: You dont need to run 64bit WAMPServer just because your OS is Windows 64bit.
In fact the 64bit PHP is not yet a complete port and is still considered 'Experimental'
Also quite a few PHP Extensions are not converted to 64bit yet as well, so it is better to stay ywith the 32bit WampServer ( Apache/MySQL/PHP ) unless you have some very specific need to use the 64bit version.
I have installed MySQL it via wizard with the installer (5.6) and seems I'm unable to load properly the my.ini file, even though the services is targeting the correct file (C:\ProgramData\MySQL\MySQL Server 5.6\my.ini), I'm a bit out of ideas already. Any suggestion?
After a server restart, MySQL still does have mysql_query_cache OFF and 0 as size.
I'm using mysql_cache_type=1 through the my.ini, but after server restart, the changes are not applied to mysql, my.ini looks like this at this moment:

Thank you!
Im using Wampserver version 2.0 . When i try to import a sql file, either through MySQL Query Browser or PHPMyAdmin,i get the following error.
Error 2006: MySQL Server has gone away.
The size of the file is 54,528 KB.
In C:\wamp\bin\mysql\mysql5.1.30\my.ini , i set the max_allowed_packet to 100M in [mysqldump] and [wampmysqld]. I couldnt find wait_timeout variable in my.ini.
Any way to fix this problem ?. For your reference, i have given below the contents of my.ini file.

I'm using XAMPP on Windows and had the same problem.
I thought it was the timeout variable but it was max_allowed_packet.
This has fixed it:
# note the change was made at this section

net_buffer_length = 8K
read_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M
This configuration file is located at «XAMPP install directory, this is C:\XAMPP by default»\mysql\bin\my.ini.
This may be because of max_allowed_packet
Change in the my.ini/my.cnf file. Include the single line under [mysqld] in your file
max_allowed_packet=500M
now restart the MySQL service once you are done. You can see it's curent value in mysql like this:
SHOW VARIABLES LIKE 'max_allowed_packet'
You can read about it here http://dev.mysql.com/doc/refman/5.1/en/packet-too-large.html
I'm using Xampp 1.7.7 on Windows 7 and had the same problem too.
The below is what fixed it:
Increase mysql.connect_timeout value:
; Maximum time (in seconds) for connect timeout. -1 means no limit
; http://php.net/mysql.connect-timeout
mysql.connect_timeout = 10 ; it was 3 by default
Tried what I did earlier and got an other problem about 'max_allowed_packet'.
Go to mysql\bin\my.ini and find setting max_allowed_packet = 1M, then change it to 10M:
max_allowed_packet = 10M ; It was 1M by default
Hope this can help.

PhpMyAdmin Documentation:
1.16 I cannot upload big dump files (memory, HTTP or timeout problems).
Starting with version 2.7.0, the import engine has been re–written and these problems should not occur. If possible, upgrade your phpMyAdmin to the latest version to take advantage of the new import features.
The first things to check (or ask your host provider to check) are the values of upload_max_filesize, memory_limit and post_max_size in the php.ini configuration file. All of these three settings limit the maximum size of data that can be submitted and handled by PHP. One user also said that post_max_size and memory_limit need to be larger than upload_max_filesize.
There exist several workarounds if your upload is too big or your hosting provider is unwilling to change the settings:
Look at the $cfg['UploadDir'] feature. This allows one to upload a file to the server via scp, ftp, or your favorite file transfer method. PhpMyAdmin is then able to import the files from the temporary directory. More information is available in the Configuration section of this document.
Using a utility (such as BigDump) to split the files before uploading. We cannot support this or any third party applications, but are aware of users having success with it.
If you have shell (command line) access, use MySQL to import the files directly. You can do this by issuing the "source" command from within MySQL: source filename.sql.
FOR THOSE DEVELOPERS USING Mac OSX, you will need to change the max_allowed_packet from 1M to 10M within the "my.cnf" file.
max_allowed_packet = 10M
You will probably find the file "my.cnf" in one of these locations:
/etc/my.cnf (MOST LIKELY LOCATION FOR MAVERICKS USERS)
/etc/mysql/my.cnf
SYSCONFDIR/my.cnf
$MYSQL_HOME/my.cnf
defaults-extra-file (the file specified with --defaults-extra-file=path, if any)
~/.my.cnf
Steps for MySQL error 2006 solution:
Edit the “my.ini” file found at “:\xampp\mysql\bin\”.
In the my.ini file, edit the “max_allowed_packet” by increasing the value.
XAMPP default value is 1M. I updated it to 10M.
Save the my.ini file.
Restart your MySQL and Apache server in XAMPP.
I noticed this error while updating Magento from version x to y. Looking at the logs I saw there was an issue in a table.
[ERROR] Index UNQ_DH_CORE_URL_REWRITE_REQUEST_PATH_STORE_ID of databaseabc /core_url_rewrite has 2 columns unique inside InnoDB, but MySQL is asking statistics for 3 columns. Have you mixed up .frm files from different installations? See http://dev.mysql.com/doc/refman/5.1/en/innodb-troubleshooting.html
Fixing this table fixed the issue.
In my case I could truncate the table as it was an index that could be generated again.
If the increase memory size answers don't work for you, check your code for an infinite loop.
That is what I had in my code which exhausted my memory no matter what I increased it to. The stack trace gives good clues, ensure debugging is turned on, at least locally!
