篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了redis 集群安装相关的知识，希望对你有一定的参考价值。
版本：redis-4.0.2.tar.g
（一）创建reids节点
我们使用3台服务器，分别为192.168.99.129，192.168.99.153，192.168.99.171三台服务器。
192.168.99.129装 7001，7002两个节点，192.168.99.153装 7003，7004两个节点，192.168.99.171装 7005，7006两个节点.
在192.168.99.129的 /usr/local/rediscluster 下创建 7001和7002文件夹，并且将要安装的redis拷到此两个文件夹下。其余的俩台机子也这样：
[[email protected] rediscluster]# pwd /usr/local/rediscluster [[email protected] rediscluster]# ls -al total 4 drwxr-xr-x. 4 root root 28 Nov 1 08:51 . drwxr-xr-x. 14 root root 4096 Nov 1 08:47 .. drwxr-xr-x. 2 root root 31 Nov 1 08:49 7001 drwxr-xr-x. 2 root root 6 Nov 1 08:51 7002
（二）编译redis
（三）配置redis.conf,以7001节点为例。
port 7001 cluster-enabled yes bind 192.168.99.129 daemonize yes cluster-config-file 7001.conf appendonly yes
（四）依次启动各个redis
[[email protected] src]# ./redis-server ../redis.conf 17620:C 01 Nov 10:02:59.106 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 17620:C 01 Nov 10:02:59.106 # Redis version=4.0.2, bits=64, commit=00000000, modified=0, pid=17620, just started 17620:C 01 Nov 10:02:59.106 # Configuration loaded [[email protected] src]# [[email protected] src]# [[email protected] src]# ps -ef|grep redis root 17614 1 0 10:01 ? 00:00:00 ./redis-server 192.168.99.129:7001 [cluster] root 17621 1 0 10:02 ? 00:00:00 ./redis-server 192.168.99.129:7002 [cluster]
（五）执行下面命令，由于centos 7中安装的 ruby版本太低，会报错
[[email protected] redis-4.0.2]# yum install ruby
[[email protected] redis-4.0.2]# yum install rubygems
[[email protected] redis-4.0.2]# gem install redis
Fetching: redis-4.0.1.gem (100%)
ERROR: Error installing redis:
redis requires Ruby version >= 2.2.2.
升级ruby版本
安装curl
[[email protected] redis-4.0.2]# yum install curl
安装rvm
[[email protected] redis-4.0.2]# curl -L get.rvm.io | bash -s stable % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 194 100 194 0 0 246 0 --:--:-- --:--:-- --:--:-- 246 100 24090 100 24090 0 0 8210 0 0:00:02 0:00:02 --:--:-- 50503 Downloading https://github.com/rvm/rvm/archive/1.29.3.tar.gz Downloading https://github.com/rvm/rvm/releases/download/1.29.3/1.29.3.tar.gz.asc gpg: directory `/root/.gnupg‘ created gpg: new configuration file `/root/.gnupg/gpg.conf‘ created gpg: WARNING: options in `/root/.gnupg/gpg.conf‘ are not yet active during this run gpg: keyring `/root/.gnupg/pubring.gpg‘ created gpg: Signature made Sun 10 Sep 2017 04:59:21 PM EDT using RSA key ID BF04FF17 gpg: Can‘t check signature: No public key Warning, RVM 1.26.0 introduces signed releases and automated check of signatures when GPG software found. Assuming you trust Michal Papis import the mpapis public key (downloading the signatures). GPG signature verification failed for ‘/usr/local/rvm/archives/rvm-1.29.3.tgz‘ - ‘https://github.com/rvm/rvm/releases/download/1.29.3/1.29.3.tar.gz.asc‘! Try to install GPG v2 and then fetch the public key: gpg2 --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 or if it fails: command curl -sSL https://rvm.io/mpapis.asc | gpg2 --import - the key can be compared with: https://rvm.io/mpapis.asc https://keybase.io/mpapis
根据上面的提示执行命令：
[[email protected] redis-4.0.2]# curl -sSL https://rvm.io/mpapis.asc | gpg2 --import -
[[email protected] redis-4.0.2]# curl -L get.rvm.io | bash -s stable
[[email protected] redis-4.0.2]# rvm install 2.3.3
[[email protected] redis-4.0.2]# gem install redis
启动集群：
./redis-trib.rb create --replicas 1 192.168.99.129:7001 192.168.99.129:7002 192.168.99.153:7003 192.168.99.153:7004 192.168.99.171:7005 192.168.99.171:7006
进入集群进行测试：
[[email protected] src]# ./redis-cli -c -h 192.168.99.129 -p 7001 //注意必须加-c 192.168.99.129:7001> set zhang "zhang"
去别的机子查看
[[email protected] src]# ./redis-cli -c -h 192.168.99.171 -p 7005 192.168.99.171:7005> get zhang -> Redirected to slot [7942] located at 192.168.99.153:7003
