My own dpkg not installing correctly.
I run:
:~# dpkg -i foo-2.1-2.deb
when my package is done installing.
:~# ps aux | grep foo | grep -v grep
root 1718 2.2 1.4 10080 7308 ttyS0 S 11:59 0:03 dpkg -i foo-2.1-2.deb
root 1731 0.0 0.0 1720 496 ttyS0 S 11:59 0:00 /bin/sh /var/lib/dpkg/info/foo-2.1-2.postinst configure 2.1-2
I think my postinst script is not terminating correctly,
I'm missing something but don't know what.
I finally figured it out. One of my scripts called by postinst called /bin/bash which started a new shell that caused dpkg to run in the background and never finish.

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
---> Computing dependencies for mysql55-server
---> Fetching archive for mysql55-server
---> Attempting to fetch mysql55-server-5.5.49_0.darwin_14.noarch.tbz2 from https://packages.macports.org/mysql55-server

---> Activating mysql55-server #5.5.49_0
If this is a new install you might want to run:
$ sudo -u _mysql /opt/local/lib/mysql55/bin/mysql_install_db
Running that gave these instructions:
$ sudo -u _mysql /opt/local/lib/mysql55/bin/mysql_install_db
Installing MySQL system tables...

Filling help tables...
161102 13:15:44 [Note] /opt/local/lib/mysql55/bin/mysqld (mysqld 5.5.49) starting as process 54180 ...
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
_mysql 54888 0.0 0.1 2667884 6340 ?? S 1:36PM 0:00.12 /opt/local/lib/mysql55/bin/mysqld --user=_mysql
root 54885 0.0 0.0 2479468 700 ?? Ss 1:36PM 0:00.00 /opt/local/bin/daemondo --label=mysql55-server --start-cmd /opt/local/lib/mysql55/bin/mysqld --user=_mysql ; --pid=exec
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
This question bas many answers, I tried what I found – did not work
So, I tried sudo mysqld stop.
Still I see the mysql processes running:
0 317 1 0 11:15AM ?? 0:00.02 /bin/sh /usr/local/mysql/bin/mysqld_safe --datadir=/usr/local/mysql/data --pid-file=/usr/local/mysql/data/anarinsky-mbp.smartdestinations.com.pid
74 3562 317 0 11:40AM ?? 0:00.41 /usr/local/mysql/bin/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --plugin-dir=/usr/local/mysql/lib/plugin --user=mysql --log-error=/usr/local/mysql/data/anarinsky-mbp.smartdestinations.com.err --pid-file=/usr/local/mysql/data/anarinsky-mbp.smartdestinations.com.pid
The same happens if I do “sudo kill -9 3562”.
Trying to go to /Library/LaunchDaemons does not retrieve any mysql entries
ls /Library/LaunchDaemons | grep mysql
The service command does not work:
-bash: service: command not found
My Os X version is 10.9.2
There are two answers I know, it might not help since you search a long time.
1.if you install mysql from dmg, you can close it in "system preferences".
2.And besides that, you can start/stop/restart mysql by:
sudo /usr/local/mysql/support-files/mysql.server start
sudo /usr/local/mysql/support-files/mysql.server stop
sudo /usr/local/mysql/support-files/mysql.server restart
To install Homebrew, open Terminal/iTerm and run following command or check https://brew.sh/
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Install mysql
$ brew install mysql.
Install brew services first
$ brew tap homebrew/services.
Start mysql
$ brew services start mysql.
In order to avoid mysqld from auto restarting after killed, try execute all these 3 commands:
$ brew services stop mysql
$ sudo launchctl unload /Library/LaunchDaemons/com.mysql.mysql.plist
$ sudo launchctl unload /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
So i have this Dockerfile:

EXPOSE 22
CMD bash -c ' (mysqld &); /usr/sbin/apache2ctl -D FOREGROUND;/usr/sbin/sshd -D'
it builds up, no problem,MySQL and Apache start and work fine but the ssh won't work and i don't know why. openssh-server is installed.
i tried starting it up like this:
#startup.sh file
#/bin/bash
sshd
+
ADD ./startup.sh /opt/startup.sh
ENTRYPOINT ["/opt/startup.sh"]
and many other,i'm stuck.
What am i doing wrong?
you are starting apache in the foreground, hence the apachectl process will never give back the hand to the shell that started it and thus the /usr/sbin/sshd -D will never be called (unless you kill apache).
The following instruction will start both mysql and apache in the background and then sshd in the foreground:
CMD bash -c ' (mysqld &); /usr/sbin/apache2ctl start;/usr/sbin/sshd -D'
While such a CMD statement is ok for tests I would advise using a different approach for running multiple processes in a single docker container:
supervisor
phusion/baseimage
Replace below lines of code in the docker file,
RUN mkdir /var/run/sshd
RUN echo 'root:123' | chpasswd
RUN sed -i 's/PermitRootLogin without-password/PermitRootLogin yes/' /etc/ssh/sshd_config
Using these codes
RUN apt-get install -y openssh-server
RUN echo 'root:password' |chpasswd
RUN mkdir -p /var/run/sshd
this works for me.
Note: Use ssh only for debugging purpose, it is not a good practice at all.
I have freshly installed xampp-linux-1.8.1 on my Ubuntu 12.04 (Mint 13 maya) Operating system.
When run lampp, I get :

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.
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
root 6066 0.0 0.0 1772 540 pts/1 S 03:21 0:00 /bin/sh /usr/bin/mysqld_safe

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
columns_priv.MYI help_category.MYI ndb_binlog_index.MYI slow_log.frm time_zone_transition.MYI
db.frm help_keyword.frm plugin.frm tables_priv.frm time_zone_transition_type.frm
db.MYD help_keyword.MYD plugin.MYD tables_priv.MYD time_zone_transition_type.MYD
db.MYI help_keyword.MYI plugin.MYI tables_priv.MYI time_zone_transition_type.MYI
event.frm help_relation.frm proc.frm time_zone.frm user.frm
event.MYD help_relation.MYD proc.MYD time_zone_leap_second.frm user_info.frm
event.MYI help_relation.MYI proc.MYI time_zone_leap_second.MYD user_info.MYD
func.frm help_topic.frm procs_priv.frm time_zone_leap_second.MYI user_info.MYI
func.MYD help_topic.MYD procs_priv.MYD time_zone.MYD user.MYD
func.MYI help_topic.MYI procs_priv.MYI time_zone.MYI user.MYI
general_log.CSM host.frm servers.frm time_zone_name.frm
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.
