时间  2019-12-14 标签 linux centos redis 安装 部署 集群 搭建

redis下载 : http://download.redis.io/releases/redis-4.0.10.tar.gznode

  • 解压 编译 安装
//解压到local目录
# tar -xvf redis-4.0.10.tar.gz -C /usr/local/

//定位到解压目录
# cd /usr/local/redis-4.0.10/

//执行编译和安装,PREFIX必须大写
# make install PREFIX=/usr/local/redis
  • /usr/local/redis/bin目录下会生成以下文件,这时候就能够启动redis-server了
  • 这里写图片描述
# cd /usr/local/redis/bin
//在bin目录下执行命令
# ./redis-server

  • 这时候启动用的是默认的配置
  • bind 127.0.0.1
  • port 6379

  • daemonize nolinux

  • 另开一个远程客户端,进行客户端链接git

# cd /usr/local/redis-4.0.10/bin/
# cd ./redis-cli
127.0.0.1:6379> shutdown

//执行shutdown关闭redis服务
not connected>
  • 服务端能够经过CTRL+C 退出, 也能够在客户端执行shutdown退出
  • 设置服务后台启动方式
//拷贝一份配置文件到redis目录
# cp /usr/local/redis-4.0.10/redis.conf /usr/local/reids

//vi命令 修改守护进程 daemonize为yes
daemonized yes
//进入vi命令后能够经过 /daemonize快速定位

//在bin目录下带配置文件启动redis服务
# ./redis-server ../redsi.conf
23345:C 24 Aug 05:52:05.153 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

#

  • 经过Redis Desktop Manager 0.9.5远程链接redis服务github

  • 首先确认你的Linux系统已经开放了6379端口web

  • 修改配置文件,打开requirepass的注释或者直接添加一行
requirepass 你想要的验证码
//添加 bind 服务器地址
 bind 120.0.0.1
 bind 192.168.25.120(这里写你服务器的ip地址)

//启动服务,测试远程链接
# ./redis-server ../redsi.conf

//由于配置文件添加了验证,关闭服务的时候也须要验证
# ./redis-cli -a 验证码 shutdown

Redis伪集群搭建

1.使用Ruby Version Manager (RVM) 部署Rubyredis

//在线安装RVM
# \curl -sSL https://get.rvm.io | bash -s stable
//在线部署Ruby,列出全部版本

2.安装RubyGems
安装包下载 : https://rubygems.org/rubygems/rubygems-2.7.7.tgzsql

//解压rubygems.tgz后,在解压目录内执行
# ruby setup.rb

//验证版本
# gem -v
2.7.7

3.在线安装redis.gemruby

//会安装最新版本的redis.gem
# gem install redis

4.配置多个redis服务端bash

//新建redis-cluster文件夹
# mkdir /usr/local/redis-cluster

//删除bin目录下生成的RDB快照文件和AOF文件
# rm -rf /usr/local/redis/bin/dump.rdb appendonly.aof

/* 修改redis.conf配置文件 1.注释掉bind 127.0.0.1 2.注释掉requirepass 验证码 3.开启cluster-enabled yes的注释 4.修改protected-mode 为 no */

# bind 127.0.0.1
# requirepass 验证码
cluster-enabled yes
protected-mode no

//拷贝6份redis目录到redis-cluster *集群至少须要3个redis服务,每一个reids还须要一个备份.因此须要6份*
# cp /usr/local/redis /usr/local/redis-cluster/redis01 -r
# cp /usr/local/redis /usr/local/redis-cluster/redis02 -r
# cp /usr/local/redis /usr/local/redis-cluster/redis03 -r
# cp /usr/local/redis /usr/local/redis-cluster/redis04 -r
# cp /usr/local/redis /usr/local/redis-cluster/redis05 -r
# cp /usr/local/redis /usr/local/redis-cluster/redis06 -

//修改redis01-06目录中配置文件redis.conf,更改端口号port
redis01/reids.conf  port 7001
redis02/reids.conf  port 7002
redis03/reids.conf  port 7003
redis04/reids.conf  port 7004
redis05/reids.conf  port 7005
redis01/reids.conf  port 7006

//拷贝redis解压目录src下的redis-trib.rb到redis-cluster目录下
# cp /usr/local/redis-4.0.10/src/redis-trib.rb /usr/local/redis-cluster

//新建批执行文件
# mkdir /usr/local/redis-cluster/redis_start_all.sh

//修改批执行
# vi /usr/local/redis-cluster/redis_start_all.sh
d /usr/local/redis-cluster/redis01/bin
./redis-server ../redis.conf

cd /usr/local/redis-cluster/redis02/bin
./redis-server ../redis.conf

cd /usr/local/redis-cluster/redis03/bin

cd /usr/local/redis-cluster/redis04/bin
./redis-server ../redis.conf

cd /usr/local/redis-cluster/redis05/bin
./redis-server ../redis.conf

cd /usr/local/redis-cluster/redis06/bin
./redis-server ../redis.conf

//修改redis_start_all.sh的可执行权限
# chmod u+x /usr/local/redis-cluster/redis_start_all.sh

//启动多个redis服务,在redis-cluster目录下执行
# ./redis_start_all.sh

5.使用ruby脚本搭建集群服务器

//在redis-cluster目录下执行

大功告成

可能遇到的错误 [ERR] Sorry, can’t connect to node 192.168.X.X 检查redis.conf配置文件 bind是否为本身的服务器地址 protected-mode 是否为no requirepass是否是注释掉了
