redis(1)：linux下如何安装配置redis及主从配置

redis的优势：支持主从备份，操做指令丰富，支持异步的数据持久化

将 redis 安装到 /usr/local/webserver/redis

1.下载安装包

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.将 src 目录下全部可执行文件复制到安装目录

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启用守护进程
pidfile /usr/local/webserver/redis/run/redis.pid --Redis以守护进程方式运行时把pid写入文件
dir /usr/local/webserver/redis/db --数据存放的目录
--------------------------------------------------------------

4.建立启动和中止服务脚本

------- 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.启动 redis 服务

/usr/local/webserver/redis/start.sh
验证证服务是否成功:
 netstat -nlpt | grep 6379

6.启动客户端验证

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

二. M/S主从集群配置

1台Master和一台Slave

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

2.复制slave目录，方便管理

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

3.修改slave的配置文件和服务脚本

-- 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.启动M/S服务

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

验证服务是否正常

netstat -nlpt | grep redis-server

5.验证redis是否有效

/usr/local/webserver/redis/redis-cli [默认链接端口:6379 的 Master服务]
>set key1 val1
>quit

/usr/local/webserver/redis/redis-cli -p 63791 [链接 Slave1 服务]
>get key1
“val1″ (数据成功同步了)

多个slave同理配置
