Redis Startup Process

There are two types of redis startup: development environment and production environment.

I. Development Environment

1. CD redis-2.8.13/src

2../redis-Server start the server

3.../redis-cli start the client

Ii. Production Environment (started with the System)

1. Configure the redis initialization script (sample in/redis-2.8.13/utils/) and put it under/etc/init. d/(named redis_6379)

#! /Bin/sh

#

# Simple redis init. d script conceived to work on Linux systems

# As it does use of the/proc filesystem.

Redisport = 6379

Exec =/usr/local/bin/redis-Server

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

Pidfile =/var/run/redis _ $ {redisport}. PID

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"

;;

How to modify the initialization script file: Modify the port number of the redis server to listen to: 6379 (default)

 

2. Create a directory in the/etc directory:/etc/redis and/var/redis/6379, and store the corresponding files.

1,/etc/redis/storage configuration file, named 62.16.cof (template in the source code directory/redis-2.8.13 /)

EDIS configuration file example

Daemonize no // change to yes to enable redis to start in daemonize Mode

Pidfile/var/run/redis. PID // modify it to/var/run/redis_62.16.pid to set the path of the redis PID File

Port 6379 // change to 6379 listening port number

2. store persistent files in the/var/redis/port number directory (when this component is used)

3. sudo update-rc.d redis_6379 defaults (configure the random start command redis_6379 to initialize the script file)
