The startup mode 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 &

Or

Modify redis.conf parameters

Daemonize yes

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.

# Port that the redis server listens to

REDISPORT=6379

# where the server is located

EXEC=/usr/local/bin/redis-server

# client location

CLIEXEC=/usr/local/bin/redis-cli

# PID file location of redis, which needs to be modified

PIDFILE=/var/run/redis_$ {REDISPORT} .pid

# redis's configuration file location, you need to modify ${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/redis

Cp 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 the service

Service redisd start

# disable the service

Service redisd stop
