This article mainly introduces what are the three startup modes of redis. It is very detailed and has a certain reference value. Friends who are interested must read it!

What is the redis startup command?

Three startup modes of redis

1. Direct start

Go to the redis root directory and execute the command:

# add'&'to make redis run as a daemon

. / redis-server &

two。 Start by specifying a configuration file

You can specify a profile for redis service startup, such as / etc/redis/6379.conf

Enter the redis root directory and enter the command:

. / redis-server / etc/redis/6379.conf

# if you change the port, you also need to specify the port when you use the `redis- cli` client to connect, for example:

Redis-cli-p 6380

3. Use the redis startup script to set up boot self-startup

The startup script redis_init_script is located in the / utils/ directory of Redis, and the redis_init_script script code is as follows:

#! / bin/sh## Simple Redis init.d script conceived to work on Linux systems# as it does use of the / proc filesystem. # redis server listens to the port REDISPORT=6379 # server location EXEC=/usr/local/bin/redis-server # client location CLIEXEC=/usr/local/bin/redis-cli # redis PID file location, you need to modify the configuration file location of PIDFILE=/var/run/redis_$ {REDISPORT} .pid # redis Change ${REDISPORT} to the file name CONF= "/ etc/redis/$ {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

According to the startup script, copy the modified configuration file to the specified directory and use the root user to do the operation:

Mkdir / etc/rediscp redis.conf / etc/redis/6379.conf

Copy the startup script to the / etc/init.d directory. In this example, the startup script is named redisd (usually ending in d to indicate a background self-starting service).

Cp redis_init_script / etc/init.d/redisd

Set to boot self-startup, directly configure to enable self-boot chkconfig redisd on found error: service redisd does not support chkconfig

As a workaround, modify the run level by adding the following comments at the beginning of the startup script:

#! / bin/sh# chkconfig: 2345 90 10

Just set it again.

# set to boot self-starting server chkconfig redisd on# open service service redisd start# close service service redisd stop above are all the contents of what the three startup modes of redis are, thank you for reading!
