Redis configuration file

The main problem was that redis. pid was not found.

Below is my configuration file

# By default Redis does not run as a daemon. Use 'yes' if you need it.# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.daemonize yes# When running daemonized, Redis writes a pid file in /var/run/redis.pid by# default. You can specify a custom pid file location here.

Execution permission of var/run

lrwxrwxrwx  1 root root        4 Feb 24 06:57 run -> /run

Then I use sudo touch redis. pid

root@ubuntu:/home/fuhui/redis-2.8.19/utils# pwd/home/fuhui/redis-2.8.19/utilsroot@ubuntu:/home/fuhui/redis-2.8.19/utils# sh redis_init_script stop/var/run/redis_6379.pid does not exist, process is not running

I don't know if it is a permission issue. Modify the o permission.

fuhui@ubuntu:/var/run$ sudo chmod o+wx redis.pid-rw-r--rwx 1 root       root          0 Jun 22 08:39 redis.pid

Is the service not restarted?

fuhui@ubuntu:/var/run$ ps -ef | grep 'redis'fuhui     2452     1  0 07:55 ?        00:00:04 redis-2.8.19/src/redis-server *:6379                 fuhui     2908  2756  0 08:46 pts/13   00:00:00 grep --color=auto redisfuhui@ubuntu:/var/run$ kill -9 2452fuhui@ubuntu:/var/run$ ps -ef | grep 'redis'fuhui     2910  2756  0 08:46 pts/13   00:00:00 grep --color=auto redis

Try again:
Get it done. redis. pid has the pid Number.

Disable redis Service

Modify shell files
The following is the original file. What we need to do is simply change the path to the actual storage.

#!/bin/sh## Simple Redis init.d script conceived to work on Linux systems# as it does use of the /proc filesystem.REDISPORT=6379EXEC=/usr/local/bin/redis-serverCLIEXEC=/usr/local/bin/redis-cliPIDFILE=/var/run/redis_${REDISPORT}.pidCONF="/etc/redis/${REDISPORT}.conf"case "$1" in    start)        if [ -f $PIDFILE ]        then                echo "$PIDFILE exists, process is already running or crashed"        else                echo "Starting Redis server..."                $EXEC $CONF        fi        ;;    stop)        if [ ! -f $PIDFILE ]        then                echo "$PIDFILE does not exist, process is not running"        else                PID=$(cat $PIDFILE)                echo "Stopping ..."                $CLIEXEC -p $REDISPORT shutdown                while [ -x /proc/${PID} ]                do                    echo "Waiting for Redis to shutdown ..."                    sleep 1                done                echo "Redis stopped"        fi        ;;    *)        echo "Please use start or stop as first argument"        ;;esac

Modify as follows:

root@ubuntu:/home/fuhui/redis-2.8.19/utils# cp redis_init_script ../redis_script

Check whether pid exists In proc.

fuhui@ubuntu:/proc$ cd /proc/fuhui@ubuntu:/proc$ ls -lh | grep 2912dr-xr-xr-x  9 root       root          0 Jun 22 08:47 2912
