centos 安装 redis3.0.0 集群

2019阿里云双11返场狂欢继续,
地址https://www.aliyun.com/1111/2019/home

推荐:redis3 集群配置(一)

[Redis是一个开源的内存数据存储框架,可以当作一个缓存数据库来使用,支持strings,hashes,lists,sets, sorted sets等多种数据格式的范围查询,支持bitmaps,hyperloglogs和

这里创建6个redis节点,其中三个为主节点,三个为从节点。

redis和端口对应关系:

127.0.0.1:7000

127.0.0.1:7001

127.0.0.1:7002

从:

127.0.0.1:7003
127.0.0.1:7004
127.0.0.1:7005

步骤:
1,下载redis。官网下载3.0.0版本,之前几的版本不支持集群模式

下载地址:http://download.redis.io/releases/redis-3.0.0.tar.gz


2:上传服务器,解压,编译
tar -zxvf redis-3.0.0.tar.gz
mv redis-3.0.0 redis3.0
cd /usr/local/redis3.0
make & make install


3:创建集群需要的目录并拷贝redis
mkdir -p /usr/local/cluster
mkdir -p /usr/local/cluster/7000
mkdir -p /usr/local/cluster/7001
mkdir -p /usr/local/cluster/7002
mkdir -p /usr/local/cluster/7003
mkdir -p /usr/local/cluster/7004
mkdir -p /usr/local/cluster/7005
cp -rf /usr/local/redis3.0/* /usr/local/cluster/7000/
cp -rf /usr/local/redis3.0/* /usr/local/cluster/7001/
cp -rf /usr/local/redis3.0/* /usr/local/cluster/7002/
cp -rf /usr/local/redis3.0/* /usr/local/cluster/7003/
cp -rf /usr/local/redis3.0/* /usr/local/cluster/7004/
cp -rf /usr/local/redis3.0/* /usr/local/cluster/7005/


4:修改配置文件redis.conf

vi /usr/local/cluster/7000/redis.conf

##修改配置文件中的下面选项
port 7000
daemonize yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
appendonly yes


#同样再对其它配置文件进行修改
vi /usr/local/cluster/7001/redis.conf
vi /usr/local/cluster/7002/redis.conf
vi /usr/local/cluster/7003/redis.conf
vi /usr/local/cluster/7004/redis.conf
vi /usr/local/cluster/7005/redis.conf
##注意:不同的目录配置不同的redis.conf中的port


5:启动6个redis

cd /usr/local/cluster/7000/src
redis-server ../redis.conf
cd /usr/local/cluster/7001/src
redis-server ../redis.conf
cd /usr/local/cluster/7002/src
redis-server ../redis.conf
cd /usr/local/cluster/7003/src
redis-server ../redis.conf
cd /usr/local/cluster/7004/src
redis-server ../redis.conf
cd /usr/local/cluster/7005/src
redis-server ../redis.conf

##启动之后使用命令查看redis的启动情况ps -ef|grep redis


6,创建redis集群
cd /usr/local/redis3.0/src
./redis-trib.rb  create --replicas 1 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005

6.1执行上面的命令的时候会报错,因为是执行的的脚本,需要
错误内容:/usr/bin/env: ruby: No such file or directory
所以需要安装ruby的环境,这里推荐使用yum install ruby


yum install ruby


6.2然后再执行第步的创建集群命令,还会报错,提示缺少rubygems组件
错误内容:
./redis-trib.rb:24:in `require': no such file to load -- rubygems (LoadError)
from ./redis-trib.rb:24
yum install rubygems


6.3再次执行第步的命令,还会报错,提示不能加载redis,是因为缺少redis的接口
错误内容:
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- redis (LoadError)
from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
from ./redis-trib.rb:25


gem install redis
这里可能无法安装,因为无法连接gem服务器:
[@zw_22_90 src]# gem install redis --version 3.0.0  
ERROR:  Could not find a valid gem 'redis' (= 3.0.0) in any repository
ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)


需要手工下载并安装:
wget https://rubygems.global.ssl.fastly.net/gems/redis-3.2.1.gem
gem install -l ./redis-3.2.1.gem


6.4 再次执行第步的命令,正常执行
输入yes,然后配置完成。
[@zw_22_90 src]# ./redis-trib.rb  create --replicas 1 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005

至此redis集群即搭建成功!


推荐:redis3集群安装剖析

[原文  http://www.cnblogs.com/zhongkaijun/p/4728334.html   redis3.0版本之后支持Cluster,具体介绍redis集群我就不多说,了解请看 redis中文简介 。 首先,直接访问red

7,redis-cli命令进入集群环境
[@zw_22_90 src]# redis-cli -c -p 7000

127.0.0.1:7000> quit;



参考了:http://blog.csdn.net/xu470438000/article/details/42971091,并进行了细节修改和部分补充。



今天又在公司搭建了一个集群,记录操作命令如下:

cd ~
wget http://download.redis.io/releases/redis-3.0.0.tar.gz
tar -zxvf redis-3.0.0.tar.gz
mv redis-3.0.0 redis3
cd redis3
make & make install


mkdir /opt/soft/redis3_master
mkdir /opt/soft/redis3_slave


cp -rf ~/redis3/* /opt/soft/redis3_master
cp -rf ~/redis3/* /opt/soft/redis3_slave


vi /opt/soft/redis3_master/redis.conf
=========================
#修改这几个参数为:
# <---edit by dafei 
port 7001
logfile "/opt/soft/redis3_slave/log.log"
daemonize yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
cluster-require-full-coverage yes
appendonly no
# edit by dafei --->
=========================


vi /opt/soft/redis3_slave/redis.conf
=========================
#修改这几个参数为:
# <---edit by dafei 
port 7002
logfile "/opt/soft/redis3_slave/log.log"
daemonize yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
cluster-require-full-coverage yes
appendonly no
# edit by dafei --->
=========================


#start
cd /opt/soft/redis3_master/src
redis-server ../redis.conf
cd /opt/soft/redis3_slave/src
redis-server ../redis.conf




#start the cluster at 10.10.22.95
./redis-trib.rb  create --replicas 1 ip:7001 ip:7001 ip:7001 ip:7002 ip:7002 ip:7002
#上面这个start报错,可参考:http://blog.csdn.net/lifeiaidajia/article/details/45370377
