redis单节点及集群搭建

标签：单节点   lease   conf   redis   time   gcc   efi   搭建   eve   

1.redis是单线程,高性能的key/value内存数据，基于内存运行并支持持久化的NoSQL数据库

2.redis主要用来做缓存,但不仅仅是做缓存,例如：redis的计数器生成分布式唯一主键,redis实现分布式锁,队列,会话缓存

安装单节点redis

1、安装gcc套装：
yum install cpp
yum install binutils
yum install glibc
yum install glibc-kernheaders
yum install glibc-common
yum install glibc-devel
yum install gcc
yum install make

2、升级gcc
yum -y install centos-release-scl
yum -y install devtoolset-9-gcc devtoolset-9-gcc-c++ devtoolset-9-binutils
scl enable devtoolset-9 bash

3、设置永久升级：
echo "source /opt/rh/devtoolset-9/enable" >>/etc/profile

4、安装redis：
wget http://download.redis.io/releases/redis-6.0.3.tar.gz
tar xzf redis-6.0.3.tar.gz
cd redis-6.0.3
make
make  PREFIX=/usr/local/redis install

5、修改redis.conf以daemon运行
[root@VM-55fbfec9-2204-4954-90b1-67271ee7c4b0 bin]# grep  daemon redis.conf 
daemonize yes

6、启动redis
./redis-server redis.conf 
./redis-cli 
[root@VM-55fbfec9-2204-4954-90b1-67271ee7c4b0 bin]# redis-cli 
127.0.0.1:6379> ping

安装redis集群

#创建配置文件
[root@VM-55fbfec9-2204-4954-90b1-67271ee7c4b0 kconfig]# cat redis6380.conf 
include /usr/local/bin/kconfig/redis.conf
pidfile "/var/run/redis6380.pid"
port 6380
dbfilename "dump6380.rdb"
cluster-enabled yes
cluster-config-file node-6380.conf
cluster-node-timeout 15000

#启动6个实例
[root@VM-55fbfec9-2204-4954-90b1-67271ee7c4b0 kconfig]# ps -ef|grep redis

#创建集群
