linux下如何安裝配置redis及主從配置

redis的優點：支持主從備份，操作指令豐富，支持異步的數據持久化

將 redis 安裝到 /usr/local/webserver/redis

1.下載安裝包

wget http://redis.googlecode.com/files/redis-2.2.15.tar.gz

tar zxvf redis-2.2.15.tar.gz

cd redis-2.2.15

make

mkdir -p /usr/local/webserver/redis/conf

mkdir -p /usr/local/webserver/redis/run

mkdir -p /usr/local/webserver/redis/db

cp redis.conf /usr/local/webserver/redis/conf/

cd src

2.將 src 目錄下所有可執行文件復制到安裝目錄

cp redis-benchmark redis-check-aof redis-check-dump redis-cli redis-server mkreleasehdr.sh

/usr/local/webserver/redis/

3.修改配置文件

------- vi /usr/local/webserver/redis/conf/redis.conf --------

daemonize yes  --yes啟用守護進程

pidfile /usr/local/webserver/redis/run/redis.pid --Redis以守護進程方式運行時把pid寫入文件

dir /usr/local/webserver/redis/db --數據存放的目錄

--------------------------------------------------------------

4.創建啟動和停止服務腳本

------- vi /usr/local/webserver/redis/start.sh ---------

#!/bin/bash

/usr/local/webserver/redis/redis-server /usr/local/webserver/redis/conf/redis.conf

------- vi /usr/local/webserver/redis/stop.sh ---------

#!/bin/bash

kill `cat /usr/local/webserver/redis/run/redis.pid`

chmod a+x /usr/local/webserver/redis/start.sh /usr/local/webserver/redis/stop.sh

5.啟動 redis 服務

/usr/local/webserver/redis/start.sh

驗證證服務是否成功:

netstat -nlpt | grep 6379

6.啟動客戶端驗證

/usr/local/webserver/redis/redis-cli

>set key1 val1

>get key1

二. M/S主從集群配置

1台Master和一台Slave

Master IP:127.0.0.1  PORT:6379

Slave1 IP:127.0.0.1  PORT:63791

2.復制slave目錄，方便管理

cp -r /usr/local/webserver/redis /usr/local/webserver/redis-slave1

3.修改slave的配置文件和服務腳本

-- vi /usr/local/webserver/redis-slave1/conf/redis.conf --

port 63791

pidfile /usr/local/webserver/redis-slave1/run/redis.pid

dir /usr/local/webserver/redis-slave1/db

slaveof 127.0.0.1 6379

----------------------------------------------------------

-- vi /usr/local/webserver/redis-slave1/start.sh --

#!/bin/bash

/usr/local/webserver/redis-slave1/redis-server /usr/local/webserver/redis-slave1/conf/redis.conf

---------------------------------------------------

------- vi /usr/local/webserver/redis-slave1/stop.sh ---------

#!/bin/bash

kill `cat /usr/local/webserver/redis-slave1/run/redis.pid`

--------------------------------------------------------

4.啟動M/S服務

/usr/local/webserver/redis/start.sh

/usr/local/webserver/redis-slave1/start.sh

驗證服務是否正常

netstat -nlpt | grep redis-server

5.驗證redis是否有效

/usr/local/webserver/redis/redis-cli [默認連接端口:6379 的 Master服務]

>set key1 val1

>quit

/usr/local/webserver/redis/redis-cli -p 63791 [連接 Slave1 服務]

>get key1

“val1″ (數據成功同步了)

多個slave同理配置
