I have freshly installed xampp-linux-1.8.1 on my Ubuntu 12.04 (Mint 13 maya) Operating system.
When run lampp, I get :
/opt/lampp/lampp start
Starting XAMPP for Linux 1.8.1...
XAMPP: XAMPP-Apache is already running.
XAMPP: Another MySQL daemon is already running.
XAMPP: XAMPP-ProFTPD is already running.

ps -aux | grep 'mysql'
Warning: bad ps syntax, perhaps a bogus '-'? See http://procps.sf.net/faq.html mysql 3159 0.0 0.9 316264 31880 ? Ssl 16:48 0:00 /usr/sbin/mysqld

When I tried to stop /usr/sbin/mysqld but it can't be stopped with this command !!!
/usr/sbin/mysqld stop
Please I need Help, Thanks.
i've resolved the issue in this way:
sudo chmod -R 777 /opt/lampp
sudo chown -hR nobody /opt/lampp
sudo chmod -R 755 /opt/lampp
then stop other mysqld running with:
sudo service mysql stop
Also had this issue, after troubleshooting for almost 2 hours I found that it was because of other Apache and MySQL packages also running on my system. Removed all Apache and MySQL packages and reinstalled XAMPP again. Success.

Short version: I started mysql with mysql_safe and I can't kill it.
Long version: Installing an older version of mysql with macport displayed this suggestion:
$ sudo port install mysql55-server

If this is a new install you might want to run:

Running that gave these instructions:
$ sudo -u _mysql /opt/local/lib/mysql55/bin/mysql_install_db

OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/opt/local/lib/mysql55/bin/mysqladmin -u root password 'new-password'
/opt/local/lib/mysql55/bin/mysqladmin -u root -h myusername password 'new-password'
Alternatively you can run:
/opt/local/lib/mysql55/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
cd /opt/local ; /opt/local/lib/mysql55/bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
cd /opt/local/mysql-test ; perl mysql-test-run.pl
Please report any problems at http://bugs.mysql.com/
At this point I (unwisely, it seems) ran:
$ cd /opt/local ; /opt/local/lib/mysql55/bin/mysqld_safe &
Now I cannot figure out how to stop the mysql and/or daemondo process(es):
$ ps aux | grep mysql55
myusername 54937 0.1 0.0 2432772 660 s001 R+ 1:39PM 0:00.00 grep mysql55

I've tried many variations of kill, targeting both mysql (which seems pointless) and daemondo, including (but not limited to) the following:
sudo kill -9 54888 // killing the mysql process results in a new pid
sudo kill 54885 // the doemondo process
sudo kill -SIGHUP 54885
sudo killall mysqld_safe
sudo kill -9 54822 // a reincarnation of the doemondo process
sudo mysqladmin shutdown
For centos or mint
/usr/bin# initctl
for ubuntu
pkill mysqld
MySQL already running, but when open http://localhost/phpmyadmin/ I get error like this :

when I try run from command line with sudo /opt/lampp/lampp start, I get the message like this :

I have checked in ps -aux | grep mysqld

I have CentOS 6.4 with NGINX.
When I try to start/stop/restart mysql server (/etc/init.d/mysqld restart) I get this error:
MySQL server PID file could not be found! [FAILED]
Starting MySQL..The server quit without updating PID file ([FAILED]/mysql/mysqld.pid).
What can I do to solve this problem?
Thanks!
I got the same error on a CentOS 6.3 where I upgraded MySQL to 5.6.14 but I kept the old my.cnf file. After upgrade, MySQL did not start anymore, giving me the same error as you described.
The problem was that I had this setting in my.cnf:
table_cache=2048
According to this link table_cache renamed table_open_cache..
"Seem like in 5.5 the system variable table_cache was renamed
table_open_cache..
In 5.6 mysqld fails if it finds an unknown variable
this means that upgrades from versions earlier than 5.5 can have
problems if table_cache is specified in my.cnf."
After I changed the above line to
table_open_cache=2048
MySQL started perfectly.
So, in the case you have MySQL 5.5+ (and maybe an older my.cnf), I suggest you to do the following:
remove my.cnf from /etc folder and try to start MySQL
if MySQL starts, the the problem is in my.cnf. Comment/uncomment all the settings one by one in order to see which is causing the problem.
Hope this helps.
I upgraded my Mac OS to 10.9.3 and encountered the above problem on mysql.server restart
The following fixed my problem
sudo chmod -R o+rwx /usr/local/var/mysql/
sudo chown -R mysql /usr/local/var/mysql/
sudo mysql.server restart
First of all make sure that which folder/file is not exist in /var/run/mysqld/mysqld.pid
if dir not exists then create it as:
sudo mkdir -p /var/run/mysqld/
if mysqld.pid is not exists then create it as:
sudo touch /var/run/mysqld/mysqld.pid
change ownership as:
sudo chown mysql:mysql -R /var/run/mysqld
chmod 775 -R /var/run/mysqld
restart mysql service
sudo service mysql restart
I find that sometimes MySQL processes are still running. Certainly this was the case on my OS X Yosemite system so use the following command to find any processes that show up with MySQL in the name:
ps aux | grep mysql
Then kill them using the command
sudo kill -9 PID, replacing PID with the offending process ID.
Check if there is a lock.
/etc/init.d/mysql status
If the OS says that there is a lock, something like:
ERROR! MySQL is not running, but lock file (/var/lock/subsys/mysql) exists
remove that lock file and restart.
I found this worked....
# ps aux | grep mysql

I installed mySQL on my Mac. Beside starting the SQL server with mySQL.prefPane tool installed in System Preferences, I want to know the instructions to start from command-line.
I do as follows:
After
su root
I start the mySQL server by command-line, but it produces an error as below:
sh-3.2# /usr/local/mysql/bin/mysqld

111028 16:57:43 [Note] /usr/local/mysql/bin/mysqld: Shutdown complete
Simply:

Try /usr/local/mysql/bin/mysqld_safe
Example:
shell> sudo /usr/local/mysql/bin/mysqld_safe
(Enter your password, if necessary)
(Press Control-Z)
shell> bg
(Press Control-D or enter "exit" to exit the shell)
You can also add these to your bash startup scripts:
export MYSQL_HOME=/usr/local/mysql
alias start_mysql='sudo $MYSQL_HOME/bin/mysqld_safe &'
alias stop_mysql='sudo $MYSQL_HOME/bin/mysqladmin shutdown'
I like the aliases too ... however, I've had issues with MySQLCOM for start ... it fails silently ... My workaround is akin to the others ... ~/.bash_aliases
alias mysqlstart='sudo /usr/local/mysql/support-files/mysql.server start'
alias mysqlstop='sudo /usr/local/mysql/support-files/mysql.server stop'
As this helpful article states:
On OS X to start/stop MySQL from the command line:
sudo /usr/local/mysql/support-files/mysql.server start
sudo /usr/local/mysql/support-files/mysql.server stop
On Linux start/stop from the command line:
/etc/init.d/mysqld start
/etc/init.d/mysqld stop
/etc/init.d/mysqld restart
Some Linux flavours offer the service command too
# service mysqld start
# service mysqld stop
# service mysqld restart
or
# service mysql start
# service mysql stop
# service mysql restart
If you installed it with homebrew, the binary will be somewhere like
/usr/local/Cellar/mysql/5.6.10/bin/mysqld
which means you can start it with
/usr/local/Cellar/mysql/5.6.10/support-files/mysql.server start
and stop it with
/usr/local/Cellar/mysql/5.6.10/support-files/mysql.server stop
Edit: As Jacob Raccuia mentioned, make sure you put the appropriate version of MySQL in the path.
Maybe your mysql-server didn't start.
You can try
/usr/local/bin/mysql.server start
sudo /Library/StartupItems/MySQLCOM/MySQLCOM start
sudo /Library/StartupItems/MySQLCOM/MySQLCOM stop
make alias in .bash_profile
alias start_mysql="/Library/StartupItems/MySQLCOM/MySQLCOM start"
alias stop_mysql="/Library/StartupItems/MySQLCOM/MySQLCOM stop"
and if you are trying to run as root use following safe mode
sudo ./bin/mysqld_safe
if you are still having issues starting, a recommended read:
mysql5.58 unstart server in mac os 10.6.5
For me this solution worked on mac Sierra OS:
sudo /usr/local/bin/mysql.server start
Starting MySQL
SUCCESS!
My MySQL is installed via homebrew on OS X ElCaptain. What fixed it was running
brew doctor
which suggested that I run
sudo chown -R $(whoami):admin /usr/local
Then:
brew update
mysql.server start
mysql is now running
If it's installed with homebrew try just typing down mysql.server in terminal and that should be it.
AFAIK it executable will be under /usr/local/bin/mysql.server.
If not you can always run following "locate mysql.server" which will tell you where to find such file.
If you have MySQL installed through Homebrew these commands will help you:
# For starting
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
# For stoping
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
MySql server startup error 'The server quit without updating PID file '
if you have installed mysql from homebrew
close mysql server from preferences of mac
ps ax | grep mysql
#kill all the mysql process running
sudo kill -9 pid

On mac Big Sur and MySQL 5.7, I needed to stop/start with:
sudo launchctl load -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
and
sudo launchctl unload -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
This answer came from https://coolestguidesontheplanet.com/start-stop-mysql-from-the-command-line-terminal-osx-linux/
In my case, I had downloaded the mysql server and installed it but I didn't click on the run server that showed up on the last installer page.
In order to start my server manually in the terminal (without adding aliases), I used this in the terminal and it works.
Start Server:
sudo launchctl load -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
Stop Server:
sudo launchctl unload -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist

Have you set a root password for your mysql installation? This is different to your sudo root password. Try /usr/local/mysql/bin/mysql_secure_installation
I installed mysql on ubuntu server and i dont know what went wrong...it didnt install a mysql root user so i tried to uninstall and start over and now i cant unistall
i tried this
apt-get remove php5-mysql
apt-get remove mysql-server mysql-client
apt-get autoremove
but when i do
ps aux | grep mysql

so i killed the processes and then tried to reinstall like this
apt-get -f install
sudo apt-get install mysql-server mysql-client
sudo mysqladmin -u root -h localhost password 'root'
but i get this
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'#'localhost' (using password: NO)'
im confused..i keep installing and uninstalling mysql and the same result..any ideas
it's possible that mysql is using old config files from your previous installation.
the best way to remove a package is:
sudo dpkg --purge package name
This removes all obsolete config files as well!
The root password is stored in a special "mysql" database. Look in /var/lib/mysql/mysql and see if there is anything there.
In my case, I see:
# ls /var/lib/mysql/mysql
columns_priv.frm help_category.frm ndb_binlog_index.frm slow_log.CSM time_zone_transition.frm
columns_priv.MYD help_category.MYD ndb_binlog_index.MYD slow_log.CSV time_zone_transition.MYD

general_log.CSV host.MYD servers.MYD time_zone_name.MYD
general_log.frm host.MYI servers.MYI time_zone_name.MYI
If so, delete that directory and then reinstall.
You can also start mysql in a special no-password mode and then reset the password.
