redis(1)：linux下如何安裝配置redis及主從配置

 關注微信：neihanrukou

redis的優勢：支持主從備份，操做指令豐富，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 目錄下全部可執行文件複製到安裝目錄

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啓用守護進程
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.建立啓動和中止服務腳本

------- 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.啓動 redis 服務

/usr/local/webserver/redis/start.sh
驗證證服務是否成功:
 netstat -nlpt | grep 6379

6.啓動客戶端驗證

/usr/local/webserver/redis/redis-cli
>set key1 val1
>get key1

二. M/S主從集羣配置

1臺Master和一臺Slave

Master IP:127.0.0.1  PORT:6379
Slave1 IP:127.0.0.1  PORT:63791

2.複製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.啓動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 [默認鏈接端口:6379 的 Master服務]
>set key1 val1
>quit

/usr/local/webserver/redis/redis-cli -p 63791 [鏈接 Slave1 服務]
>get key1
「val1″ (數據成功同步了)

多個slave同理配置
