I started redis server on ubuntu by typing this on terminal: $redis-server
This results in following > http://paste.ubuntu.com/12688632/
aruns ~ $ redis-server
27851:C 05 Oct 15:16:17.955 # Warning: no config file specified, using the default config. In order to specify a config file use redis-server /path/to/redis.conf
27851:M 05 Oct 15:16:17.957 # You requested maxclients of 10000 requiring at least 10032 max file descriptors.
27851:M 05 Oct 15:16:17.957 # Server can't set maximum open files to 10032 because of OS error: Operation not permitted.
27851:M 05 Oct 15:16:17.958 # Current maximum open files is 4096. maxclients has been reduced to 4064 to compensate for low ulimit. If you need higher maxclients increase 'ulimit -n'.
27851:M 05 Oct 15:16:17.958 # Creating Server TCP listening socket *:6379: bind: Address already in use
How can I fix this problem, it there any manual or automated process to fix this binding.
$ ps aux | grep redis
Find the port that its running on.. In my case..
MyUser 8821 0.0 0.0 2459704 596 ?? S 4:54PM 0:03.40 redis-server *:6379
And then close the port manually
$ kill -9 8821
Re-run redis
$ redis-server
for me, after lots of problems, this solved my issue:
root@2c2379a99b47:/home/ ps -aux | grep redis
redis 3044 0.0 0.0 37000 8780 ? Ssl 14:59 0:00 /usr/bin/redis-server *:6379
after finding redis, kill it!
root@2c2379a99b47:/home# sudo kill -9 3044
root@2c2379a99b47:/homek# sudo service redis-server restart
Stopping redis-server: redis-server.
Starting redis-server: redis-server.
root@2c2379a99b47:/home# sudo service redis-server status
redis-server is running
I read the documentation on http://www.redis.io , I opened the redis.conf file to configure the redis-server, its located at /etc/redis/redis.conf
$ sudo subl /etc/redis/redis.conf
Instead of sublime editor you can use editor of your choice, viz. nano, vi, emacs, vim, gedit.
In this file I uncommented the #bind 127.0.0.1 line. Hence, instead of 0.0.0.0:6379 now its 127.0.0.1:6379
Restart the redis server
$ sudo service redis-server restart
It will state, The server is now ready to accept connections on port 6379
This will put your server up, For any more detailed configuration and settings you can follow this redis-server on ubuntu
I solved this problem on Mac by just typing redis-cli shutdown, after this just re open the terminal and type redid-server and it will work .
I prefer to use the command param -ef,
ps -ef|grep redis
the -efmeans
-A Display information about other users' processes, including those
without controlling terminals.
-e Identical to -A.
-f Display the uid, pid, parent pid, recent CPU usage, process start
time, controlling tty, elapsed CPU usage, and the associated com-
mand. If the -u option is also used, display the user name
rather then the numeric uid. When -o or -O is used to add to the
display following -f, the command field is not truncated as se-
verely as it is in other formats.
then kill the pid
kill -9 $pid
sudo service redis-server stop
So as it says, the process is already running so the best to do is to stop it, analyse and restart it and todo so here are the following commands :
redis-cli ping #should return 'PONG'
And this solved my issue:
$ ps -ef |grep redis
root 6622 4836 0 11:07 pts/0 00:00:00 grep redis
redis 6632 1 0 Jun23 ? 04:21:50 /usr/bin/redis-server *:6379
Locate redis process, and stop it!
$ kill -9 6632
$ service redis restart
Stopping redis-server: [ OK ]
Starting redis-server: [ OK ]
$ service redis status
Otherwise if all this doesn't work just try to type redis-cli
Hope it helps :)
Killing the process that was running after booting in the OS worked for me. To prevent redis from starting at startup in Ubuntu OS:
sudo systemctl disable redis-server
