Binary File Description

• redis-cli：Redis客戶端操作工具
• redis-benchmark：Redis性能測試工具
• redis-check-aof：數據修復工具
• redis-check-dump：檢查導出工具

Configure Redis

[root@localhost redis-stable]# cd ..
## 創建Redis執行時所需的資料夾
[root@localhost software]# mkdir redis
[root@localhost software]# cd redis
[root@localhost redis]# mkdir data log run conf

## 配置Redis執行時的conf文件
[root@localhost redis]# cp ../redis-stable/redis.conf ./conf/redis_6379.conf
[root@localhost redis]# vim conf/redis_6379.conf
## ...
# Creating a pid file is best effort: if Redis is not able to create it
# nothing bad happens, the server will start and run normally.
pidfile /opt/software/redis/run/redis_6379.pid

## ...

# The working directory.
#
# The DB will be written inside this directory, with the filename specified
# above using the 'dbfilename' configuration directive.
#
# The Append Only File will also be created inside this directory.
#
# Note that you must specify a directory here, not a file name.
dir /opt/software/redis/data

## ...
# Specify the log file name. Also the empty string can be used to force
# Redis to log on the standard output. Note that if you use standard
# output for logging but daemonize, logs will be sent to /dev/null
logfile /opt/software/redis/log/redis.log

## ...
# 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

Set Redis as Service

[root@localhost redis]# cd ../redis-stable/
[root@localhost redis-stable]# cp ./utils/redis_init_script /etc/init.d/redis
[root@localhost redis-stable]# cd /etc/init.d
[root@localhost init.d]# vim redis
#!/bin/sh
# Add this for solving the error message "service redis does not support chkconfig"
# chkconfig:   2345 90 10
# description:  Redis is a persistent key-value database
#
# 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

## 對應先前設定Redis Configuration路徑
PIDFILE=/opt/software/redis/run/redis_${REDISPORT}.pid
CONF="/opt/software/redis/conf/redis_${REDISPORT}.conf"


## Test the settings is okay or not
[root@localhost init.d]# service redis start
Starting Redis server...

Set Redis as Auto-start Services on Boot

## if occur error message "service redis does not support chkconfig", add the chkconfig description in file named redis
[root@localhost init.d]# chkconfig redis on

## Reboot system for testing the auto-start settings
## Use ps command to check Redis service running state
[datacenter@localhost ~]$ ps -aux | grep redis
root        998  0.1  0.1 145248  7548 ?        Ssl  01:44   0:00 /usr/local/bin/redis-server 127.0.0.1:6379

Use Redis Client

[datacenter@localhost ~]$ redis-cli 
127.0.0.1:6379> help
redis-cli 4.0.6
To get help about Redis commands type:
      "help @<group>" to get a list of commands in <group>
      "help <command>" for help on <command>
      "help <tab>" to get a list of possible help topics
      "quit" to exit

To set redis-cli preferences:
      ":set hints" enable online hints
      ":set nohints" disable online hints
Set your preferences in ~/.redisclirc
127.0.0.1:6379>
