[memcached] How to stop and restart memcached server?

How to stop and restart memcached server 1.4.5 in linux OS from command line?

If you have an older version of memcached and need a script to wrap memcached as a service, here it is: Memcached Service Script

For me, I installed it on a Mac via Homebrew and it is not set up as a service. To run the memcached server, I simply execute memcached -d. This will establish Memcached server on the default port, 11211.

> memcached -d
> telnet localhost 11211
Trying ::1...
Connected to localhost.
Escape character is '^]'.
version
VERSION 1.4.20

As root on CentOS 7:

systemctl start memcached
systemctl stop memcached
systemctl restart memcached

To tell the service to start at reboot (ex chkconfig):

systemctl enable memcached

To tell the service to not start at reboot:

systemctl disable memcached

Log in as root or do

su -

Then:

service memcached restart

If that doesn't work, then:

/etc/init.d/memcached restart

It all depends on which Linux distro (or other OS) you're using.

if linux

if install by apt-get

service memcached stop
service memcached restart

if install by source code

Usage: /etc/init.d/memcached {start|stop|restart|force-reload|status}

can also simply kill $pid to stop

If you're using homebrew:

brew services restart memcached

This worked for me:

brew services stop memcached

sudo /etc/init.d/memcached restart

To shutdown memcache daemon:

sudo service memcached stop

To start memcached daemon:

sudo service memcached start

Restart memcached server:

sudo service memcached restart

You can see if Memcache is currently runing:

sudo ps -e | grep memcached

And you can check the TCP or UDP ports if something (e.g. Memcache) is listening to it:

netstat -ap | grep TheChosenPort#
netstat -ap | grep 11211

For some Linuxes you need to change your commands like:

sudo /etc/init.d/memcached start
sudo /etc/init.d/memcached restart
sudo /etc/init.d/memcached stop

If you want to be allowed to shutdown the memcached server you can give it that option before start it :

memcached -A &

With this option when you connect to memcached server for example:

telnet localhost 11211

then you can use shutdown command to shutdown the server. You can also shutdown the memcached server when it is run as a process, first find the process PID using:

pidof memcached

then use:

kill PID command

sudo service memcached stop

sudo service memcached start

sudo service memcached restart

Using root, try something like this:

/etc/init.d/memcached restart
