error Can t connect to local MySQL server through socket var run mysqld mysqld sock 2 -- Missing var run mysqld mysqld sock

Question

My problem started off with me not being able to log in as root any more on my mysql install   I was attempting to run mysql without passwords turned on    but whenever I ran the command   mysqld safe --skip-grant-tables  amp   I would never get the prompt back  I was trying to follow these instructions to recover the password  The screen just looks like this  root jj-SFF-PC  usr bin  mysqld safe --skip-grant-tables 120816 11 40 53 mysqld safe Logging to syslog  120816 11 40 53 mysqld safe Starting mysqld daemon with databases from  var lib mysql  and I don t get a prompt to start typing the SQL commands to reset the password  When I kill it by pressing CTRL   C  I get the following message  error   Can t connect to local MySQL server through socket   var run mysqld mysqld sock   2    Check that mysqld is running and that the socket    var run mysqld mysqld sock  exists   If I retry the command and leave it long enough  I do get the following series of messages  root jj-SFF-PC  run mysqld  120816 13 15 02 mysqld safe Logging to syslog  120816 13 15 02 mysqld safe Starting mysqld daemon with databases from  var lib mysql 120816 13 16 42 mysqld safe mysqld from pid file  var run mysqld mysqld pid ended   1    Done                    mysqld safe --skip-grant-tables root jj-SFF-PC  run mysqld   But then if I try to log in as root by doing    mysql -u root  I get the following error message  ERROR 2002  HY000   Can t connect to local MySQL server through socket   var run mysqld mysqld sock   2   I checked and  var run mysqld mysqld sock file doesn t not exist  The folder does  but not the file  Also  I don t know if this helps or not  but I ran find   -name mysqld and it came up with   var run mysqld - folder  usr sbin mysqld - file  run mysqld - folder  I m new to Linux and MySQL  so I don t know if this is normal or not  But I m including this info just in case it helps  I finally decided to uninstall and reinstall mysql  apt-get remove mysql-server apt-get remove mysql-client apt-get remove mysql-common apt-get remove phpmyadmin  After reinstalling all packages again in the same order as above  during the phpmyadmin install  I got the same error  ERROR 2002  HY000   Can t connect to local MySQL server through socket   var run mysqld mysqld sock   2   So I tried again to uninstall reinstall  This time  after I uninstalled the packages  I also manually renamed all mysql files and directories to mysql bad in their respective locations   var lib mysql   var lib mysql mysql  var log mysql  usr lib perl5 DBD mysql  usr lib perl5 auto DBD mysql  usr lib mysql  usr bin mysql  usr share mysql  usr share dbconfig-common internal mysql  etc init d mysql  etc apparmor d abstractions mysql  etc mysql  Then I tried to reinstall mysql-server and mysql-client again   But I ve noticed that it doesn t prompt me for a password   Isn t it supposed to ask for an admin password

Make sure your inaccessible socket file path is same as   var run mysqld mysqld sock   otherwise change the path as yours  Stop the mysqld    sudo  etc init d mysqld stop   If the process still runing     sudo pkill -9 mysqld   Remove the mysql directory where socket going to create  For me it did not allowed to remove  so I had to forcefully remove     sudo mkdir -p  var run mysqld   Set the ownership to the dirctory    sudo chown mysql mysql  var run mysqld   Start mysql    sudo  etc init d mysql start   Trying to connect mysql    sudo mysql -u dbuser -p

I am using XAMPP on Ubuntu  I found this error when connecting database through terminal  I solve it without any configuration because default socket file path in XAMPP is written in   opt lampp etc my cnf  as following    client   password     your password port          3306 socket         opt lampp var mysql mysql sock   now you can connect just by giving this socket path parameter with mysql command on terminal like   mysql -u root --socket  opt lampp var mysql mysql sock   and it s done without any configuration   If you don t want to type socket path everytime  then go for changing default path in my cnf by   var run mysqld mysqld sock   Provide permissions and restart mysql server

User · Answer

Using XAMPP on ubuntu    Create a folder called mysqld inside  var run directory  You can accomplish that using the command sudo mkdir  var run mysqld  Create a symbolic link to mysql sock file that is created by the XAMPP server when it is started  You can use the command sudo ln -s  opt lampp var mysql mysql sock  var run mysqld mysqld sock       Note  The mysql sock file is created when the server is started and removed when the server is stopped  so sometimes the link you created might appear to be broken but it should work as long as you have started the server using either sudo  opt lampp lampp start or any other means     Start the server if it s not already running and try executing your program again    Good luck  I hope you ll get away with it this time

I had the exactly same issue  After struggling for an hour  I found a way of correcting it without reinstalling mysql-common  mysql-client  mysql-server   First of all  go to   var run mysqld   You will find that the mysql sock does not exist  Simply remove the entire mysqld directory and recreate it and provide it necessary privileges     rm -rf  var run mysqld  amp  amp  mkdir  var run mysqld  amp  amp  chown mysql  var run mysqld    Now  Kill the mysql process in it s entirety  It might be possible that it will show you  waiting for page cleaner  on running   etc init d mysql status  command even after shutting down the service   To completely close the service  use     pkill -9 mysqld   Once the process is killed  try starting it again using     etc init d mysql start   And you will see that it works good  And also there will be no issue in stopping it too

If you have a lot of databases and tables on your system  and if you have innodb file per table set in my cnf  then your mysql server might have run out of opened objects   files  or rather the descriptors for these objects  Set a new max number with  open-files-limit   2048   and restart mysql  This approach might help when the socket is not created at all  but really this might not  not be the real problem  there is an underlying problem

To find all socket files on your system run   sudo find   -type s   My Mysql server system had the socket open at  var lib mysql mysql sock  Once you find where the socket is being opened  add or edit the line to your  etc my cnf file with the path to the socket file   socket  var lib mysql mysql sock   Sometimes the system startup script that launched the command line executable specifies a flag --socket path  This flag could override the my cnf location  and that would result in a socket not being found where the my cnf file indicates it should be   Then when you try to run the mysql command line client  it will read my cnf to find the socket  but it will not find it since it deviates from where the server created one   So  Unless you care where the socket resides  just changing the my cnf to match should work     Then  stop the mysqld process   How you do this will vary by system   If you re super user in the linux system  try one of the following if you don t know the specific method your Mysql setup uses    service mysqld stop  etc init d mysqld stop mysqladmin -u root -p shutdown Some systems aren t setup to have an elegant way to stop mysql  or for some reason mysql doesn t respond  and you can force terminate mysql with either    One step  pkill -9 mysqld Two step  least preferred     Find the process id of mysql with either pgrep mysql or ps aux   grep mysql   grep -v grep Assuming the process id is 4969 terminate with kill -9 4969     After you do this you might want to look for a pid file in  var run mysqld  and delete it  Make sure the permissions on your socket is such that whatever user mysqld is running as can read write to it   An easy test is to  open it up to full read write and see if it still works   chmod 777  var run mysqld mysqld sock   If that fixes the issue  you can tailor the permissions and ownership of the socket as needed based on your security settings     Also  the directory the socket resides in has to be reachable by the user running the mysqld process

I would also check the mysql configuration  I was running into this problem with my own server but I was a bit too hasty and misconfigured the innodb buffer pool size for my machine   innodb buffer pool size   4096M  It usually runs fine up to 2048 but I guess I don t have the memory necessary to support 4 gigs   I imagine this could also happen with other mysql configuration settings

Try the following at a terminal prompt   sudo mysql   Once that lets you in  you can create a new user and grant privileges that you want on the specific database they need access to    Mysql 5 7 changed some things and by default uses the auth socket plugin  as opposed to mysql native password   for root to protect the account from getting hacked   You can override this by setting the plugin field for root  but unless you have a very good reason you probably shouldn t circumvent the protection   Especially when sudo mysql is easier than mysql -u root -p anyway    I found out this info - of all places - from a Raspberry Pi help site  Worked like a charm after Lubuntu 18 04 annoyed the heck out of me for a couple hours

I run my MySQL on a virtual machine in Ubuntu  So what had happened was when I restarted my host and the VM  The IP had changed  I had configured mysql to run on IP 192 168 0 5 and now due to dynamic allocation of IP  my new IP was 192 168 0 8  If you have the same problem just check your ip with the command ifconfig   Check your MySQL binding with the command cat  etc mysql my cnf   grep bind-address  If both IP are the Same  then reinstall your mysql server  If not  then change your IP in  etc network interfaces using nano  vi  vim or anything of your preference   I prefer sudo nano  etc network interfaces  and enter the following  auto eth0 iface eth0 inet static address 192 168 0 5 netmask 255 255 255 0   Save the interfaces file  restart your interface sudo ifdown eth0  amp  amp  sudo ifup eth0 replace  eth0  with your network interface  Restart MySQL sudo service mysql stop followed by sudo service mysql start  If you have the same issue as mine  You are good to go

The solution is way easier       First  you have to locate in Terminal with  sudo find   -type s   where your mysql sock file is located  In my case it was in  opt lampp var mysql mysql sock   Fire up Terminal and issue  sudo Nautilus This starts your Files manager with super user privileges   From Nautilus navigate to where your mysql sock file is located   Right click on the file and select Make Link Rename the Link File to mysqld sock then Right click on the file and Cut it Go to  var run and create a folder called mysqld and enter it Now right click and Paste the Link File Voila  You will now have a mysqld sock file at  var run mysqld mysqld sock
