Stuck, no error message

View the running status of redisps -ef | grep redis

No screenshots: There is redis running at that time, it should be in suspended animation, restart/stop will not work

Solutions:

1. Try to kill the process and restart it:


ps -ef | grep redis | awk '{print $2}' | xargs kill -9

Copy the code

Pipe “|” is used to separate two commands, pipe the output of the command on the left will act as a pipe, the right of the command input.

Ps -ef # Displays all processes

Ps – ef | grep redis # view contains the redis process

Ps – ef | grep redis | grep -v grep # view contains the redis process, and eliminate process with grep

Awk ‘{print $2}’ # Reads the specified file line by line, using Spaces as delimiter, and printing the second field

The xargs command takes the output of the previous command (PID) as the parameter of the “kill -9″ command and executes the command. Kill -9” will forcibly kill the specified process.

2. Restart the server

Extended memory query command:

Du -sh * # Displays the size of each directory and file in the current directory

Du -sh bin* # Summarizes the size of the specified directory

Du – sh * | grep M # all directories and files under the current directory, respectively, to carry on the summary, and use grep “[M]” screen all size of M (signs) level of directories and files

Du – sh * | grep (MG) | sort – nt # screen size for MB and GB level of directories and files, descending sort – nt
