centos 安装 redis3.0.0 集群
阅读量：3555 次
发布时间：2019-05-20

本文共 8340 字，大约阅读时间需要 27 分钟。

这里创建6个节点，其中三个为主节点，三个为从节点。

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

此时可能遇到的问题

1：edis.clients.jedis.exceptions.JedisDataException:ERR This instance has cluster support disabled

解决办法： 

修改redis.config，添加cluster-enabled yes

2：启动报错

from ./redis-trib.rb:820:in create_cluster_cmd' 
from ./redis-trib.rb:1026:insend’ 
from ./redis-trib.rb:1026 
经检查，这是由于上一次配置集群失败时留下的配置信息导致的。 只要把redis.conf中定义的 cluster-config-file 所在的文件删除，重新启动redis-server及运行redis-trib即可。


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！


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/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/lifeiaidajia/article/details/45370377
