CentOS7.2 安装redis 3.0.6集群
1.环境确认

a.系统版本查看

[hadoop@p168 ~]$ cat /etc/redhat-release

CentOS Linux release 7.2.1511 (Core)

b.安装依赖

[hadoop@p168 ~]$ sudo yum -y install tcl ruby tree

2.安装redis 3.0.6

[hadoop@p168 ~]#cd /usr/local/

[hadoop@p168 ~]#wget http://download.redis.io/redis-stable.tar.gz

[hadoop@p168 ~]#tar  xzf redis-stable.tar.gz

[hadoop@p168 ~]#cd redis-stable

[hadoop@p168 ~]#make

[hadoop@p168 ~]#make test

[hadoop@p168 ~]#make install

3.建立节点配置目录

[hadoop@p168 ~]#mkdir /etc/redis

[hadoop@p168 ~]#mkdir /etc/redis/7000

4.建立节点配置文件

a.配置7000节点,先复制redis-server与初始配置文件redis.conf,然后修改redis.conf,使其适合集群

[hadoop@p168 ~]#cp /usr/local/redis-stable/src/redis-server /usr/local/redis-stable/redis.conf /etc/redis/7000

修改redis.conf,主要修改内容如下:

[hadoop@p168 ~]#vim /etc/redis/7000/redis.conf

#/etc/redis/7000/redis.conf

port 7000

daemonize    yes

pidfile  /var/run/redis_7000.pid

cluster-enabled yes

cluster-config-file nodes.conf

logfile "/var/log/redisd7000.log"

dir /etc/redis/7000/

cluster-node-timeout 5000

appendonly yes

b.复制其他节点配置文件

#生成7001配置,其他类似

cp -r 7000 7001

sed -i "s/7000/7001/g" 7001/redis.conf

cat  7001/redis.conf |grep 7001

5.配置节点开机启动

修改redisd7000的启动脚本,7001~7005类似

[hadoop@p168 ~]#cp /usr/local/redis-stable/utils/redis_init_script /etc/init.d/redisd7000

[hadoop@p168 ~]#vim  /etc/init.d/redisd7000

#!/bin/sh

#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=7000

#EXEC=/usr/local/bin/redis-server

EXEC=/etc/redis/${REDISPORT}/redis-server

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

PIDFILE=/var/run/redis_${REDISPORT}.pid

#CONF="/etc/redis/${REDISPORT}.conf"

CONF="/etc/redis/${REDISPORT}/redis.conf"

主要修改内容包括如下三点:

a.加入前三行即

#!/bin/sh

#chkconfig:    2345 90 10

#description:  Redis is a persistent key-value database
b.修改端口,即

REDISPORT=7000
c.指定EXEC与CONF即

EXEC=/etc/redis/${REDISPORT}/redis-server

CONF="/etc/redis/${REDISPORT}/redis.conf"

其他的不动,略

复制生成其他启动脚本

#生成7001脚本,其他类似

cp /etc/init.d/redisd7000 /etc/init.d/redisd7001

sed -i "s/7000/7001/g" /etc/init.d/redisd7001
cat   /etc/init.d/redisd7001 |grep 7001

#设置为开机自启动服务器,其他服务类似

[hadoop@p168 ~]#chkconfig redisd7000 on

确认配置文件,重启前应该是如下状态

[root@p161 ~]# ls /etc/init.d/ |grep redis

redisd7000

redisd7001

redisd7002

redisd7003

redisd7004

redisd7005

注:以上文件是6个服务的自动启动脚本

[root@p161 ~]# tree /etc/redis

/etc/redis

├── 7000

│   ├── redis.conf

│   └── redis-server

├── 7001

│   ├── redis.conf

│   └── redis-server

├── 7002

│   ├── redis.conf

│   └── redis-server

├── 7003

│   ├── redis.conf

│   └── redis-server

├── 7004

│   ├── redis.conf

│   └── redis-server

├── 7005

│   ├── redis.conf

│   └── redis-server

注:以上目录是各服务器的redis-server可执行程序与其配置文件,若没有tree命令,先 yum install -y tree

[hadoop@p168 ~]# reboot

重启以后服务应该就启动了,若有需要可以用如下命令来启动或停止服务了

service redisd7000 start

service redisd7000 stop

6.安装redis接口

#rubygems.org被墙,换ruby.taobao.org

gem sources --remove https://rubygems.org/

gem sources -a https://ruby.taobao.org/

gem install redis

7.建立集群

[root@p161 redis-stable]# /usr/local/redis-stable/src/redis-trib.rb  create --replicas 1 192.168.1.161:7000 192.168.1.161:7001 192.168.1.161:7002 192.168.1.161:7003 192.168.1.161:7004 192.168.1.161:7005

11.python测试

先安装pip install redis-py-cluster
注意在集群中 pip install redis安装的redis会报错!!!

from rediscluster import StrictRedisCluster
startup_nodes = [{"host": "192.168.1.161", "port": "7000"}]
rc = StrictRedisCluster(startup_nodes=startup_nodes, decode_responses=True)
rc.set("blog", "http://blog.csdn.net/dgatiger")
print rc.get('blog')

CentOS7.2 安装redis 3.0.6集群

1.环境确认
