centos7|centos7 redis安装/集群部署/slots迁移 centos7redis安装

一.安装依赖 1.ruby

安装 yum install ruby
安装后查看版本 ruby -v (redis依赖版本为2.0以上)
若不满足则卸载 yum remove ruby ruby-devel
重新安装

方法一：换yum源安装

yum install centos-release-scl-rh//会在/etc/yum.repos.d/目录下多出一个CentOS-SCLo-scl-rh.repo源
yum install rh-ruby25-y//直接yum安装即可
sclenablerh-ruby25 bash//必要一步
ruby -v//查看安装版本

方法二：下载tar压缩包安装

wget http://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.5.tar.gz
【centos7|centos7 redis安装/集群部署/slots迁移】tar zxvfruby-2.3.5.tar.gz
cd ruby-2.3.5
./configure--prefix=/opt/ruby
make && make install
ln -s /opt/ruby/bin/ruby /usr/bin/ruby
ln -s /opt/ruby/bin/gem /usr/bin/gem
ruby -v//查看一下

方法三：RVM 安装

gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E37D2BAF1CF37B13E2069D6956105BD0E739499BDB
可能会等待一段时间，然后执行下面命令：
curl -sSL https://get.rvm.io | bash -s stable
source/etc/profile.d/rvm.sh//按照提示，执行该命令
rvm list known// list一下可以安装的版本
rvm install 2.4.1// 直接跟版本号即可
ruby -v//查看验证下已经安装的版本
gem -v

2.gem

yum install rubygems

3.redis接口

下载https://rubygems.org/gems/redis/versions/3.3.5
gem install -l redis-3.3.5.gem
gem list|grep redis //查看安装版本

二.redis 1.安装

下载源码http://download.redis.io/releases/redis-4.0.1.tar.gz
安装redis需要先将官网下载的源码进行编译，编译依赖gcc环境，如果没有gcc环境，需要安装gcc：yum install gcc-c++
解压命令：
tar -zxvf redis-4.0.1.tar.gz
//进入解压后的目录进行编译
cd /usr/local/redis-4.0.1
make
//安装到指定目录,如 /usr/local/redis
cd /usr/local/redis-4.0.1
make PREFIX=/usr/local/redis install

2.配置文件

appendfsync everysec
# appendfsync no
cluster-enabled yes
cluster-config-file nodes-7001.conf
cluster-node-timeout 15000
masterauth "****"
requirepass "****"

3.启动

/home/test/redis/bin/redis-server /home/test/redis/7001/redis11.conf
/home/test/redis/bin/redis-server /home/test/redis/7002/redis12.conf
/home/test/redis/bin/redis-server /home/test/redis/7003/redis13.conf

4.检测

ps -el | grep redis

5.创建集群

/home/test/redis/bin/redis-trib.rb create --replicas 1 192.168.182.128:7001 192.168.182.128:7002 192.168.182.128:7003 192.168.182.129:7001 192.168.182.129:7002 192.168.182.129:7003

6.连接

/home/test/redis/bin/redis-cli -c -h 192.168.182.128 -p $1 -a ****

三.sentinel 1.配置

bind 192.168.182.128
port 27001
daemonize yes
dir /tmp
sentinel monitor mymaster1 192.168.182.128 7001 2
sentinel monitor mymaster2 192.168.182.128 7002 2
sentinel monitor mymaster3 192.168.182.129 7001 2
sentinel down-after-milliseconds mymaster1 30000
sentinel down-after-milliseconds mymaster2 30000
sentinel down-after-milliseconds mymaster3 30000
sentinel parallel-syncs mymaster1 1
sentinel parallel-syncs mymaster2 1
sentinel parallel-syncs mymaster3 1
sentinel failover-timeout mymaster1 180000
sentinel failover-timeout mymaster2 180000
sentinel failover-timeout mymaster3 180000

2.启动

/home/test/redis/bin/redis-sentinel /home/test/redis/sentinel/sentinel.conf

3.检查

ps -el | grep sentinel

四.redis集群增减节点/迁移slots 1.新增主节点

redis-trib.rb add-node192.168.182.130:7001 192.168.182.128:7001

2.新增从节点

redis-trib.rb add-node –-slave 192.168.182.130:7003 192.168.182.128:7001
redis-trib.rb add-node –-slave 192.168.182.130:7002 192.168.182.128:7001

3.密码

//使密码失效
CONFIG SET masterauth ""
CONFIG SET requirepass ""
config rewrite
//添加密码
CONFIG SET masterauth ****
CONFIG SET requirepass ****
config rewrite

4.迁移solt
