安装

# （三台）安装 C 语言需要的 GCC 环境
yum install -y gcc-c++ 
yum install -y wget
# 下载并解压缩 Redis 源码压缩包
wget http://download.redis.io/releases/redis-5.0.5.tar.gz 
tar -zxf redis-5.0.5.tar.gz -C ../servers/
# 编译 Redis 源码，进入 redis-5.0.5 目录，执行编译命令
cd redis-5.0.5/src 
make
# 安装 Redis ，需要通过 PREFIX 指定安装路径
mkdir /opt/bigdata/servers/redis-cluster/master1 -p 
make install PREFIX=/opt/bigdata/servers/redis-cluster/master1

注error：

# make 时 出现：
# zmalloc.h:50:31: fatal error: jemalloc/jemalloc.h: No such file or directory
make MALLOC=libc
# You need tcl 8.5 or newer in order to run the Redis test
yum install tcl -y

需求

（1）搭建Redis5.0集群，要求三主三从，记录下安装步骤

（2）能够添加一主一从（Master4和Slaver4），记录下安装步骤

（3）能够通过JedisCluster向RedisCluster添加数据和取出数据

解答

集群规划

虚拟机ip	持有角色	端口
linux01:192.168.80.121	master1 slaver1	6379 6380
linux02:192.168.80.122	master2 slaver2	6379 6380
linux03:192.168.80.123	master3 slaver3	6379 6380
linux01:192.168.80.121(准备添加主从)	master4 slaver4	7000 7001

编辑配置文件

# 1.拷贝conf文件到bin下
[root@linux02 redis-5.0.5]# cp redis.conf ../redis/bin/
# 2.编辑conf文件69 # bind 127.0.0.1		# 注掉bind 允许外界访问
88 protected-mode no	# 将yes改成no，允许外界访问
92 port 6379			# 端口号
136 daemonize yes		# 将no改成yes，允许后台启动
832 cluster-enabled yes	# 开启cluster

分配启动目录

# 拷贝出从机
[root@linux01 redis-cluster]$ cp -r master1/ slaver1
# 修改 端口号
[root@linux01 ~]$ sed -i '92c port 6380' /opt/bigdata/servers/redis-cluster/slaver1/bin/redis.conf
# 查看 修改结果
[root@linux01 ~]$ sed -n '92p' /opt/bigdata/servers/redis-cluster/slaver1/bin/redis.conf
# 发送给 其他两台
[root@linux01 servers]$ rsync -rvl /opt/bigdata/servers/redis-cluster root@linux02:/opt/bigdata/servers/
[root@linux01 servers]$ rsync -rvl /opt/bigdata/servers/redis-cluster root@linux03:/opt/bigdata/servers/
# 修改名称
[root@linux01 servers]$ ssh root@linux02 mv /opt/bigdata/servers/redis-cluster/master1/ /opt/bigdata/servers/redis-cluster/master2/
[root@linux01 servers]$ ssh root@linux02 mv /opt/bigdata/servers/redis-cluster/slaver1/ /opt/bigdata/servers/redis-cluster/slaver2
[root@linux01 servers]$ ssh root@linux03 mv /opt/bigdata/servers/redis-cluster/master1/ /opt/bigdata/servers/redis-cluster/master3/
[root@linux01 servers]$ ssh root@linux03 mv /opt/bigdata/servers/redis-cluster/slaver1/ /opt/bigdata/servers/redis-cluster/slaver3/
# 准备 master4 slaver4
[root@linux01 servers]$ cd /opt/bigdata/servers/redis-cluster/
[root@linux01 redis-cluster]$ cp -r master1/ master4
[root@linux01 redis-cluster]$ cp -r master1/ slaver4
[root@linux01 redis-cluster]$ sed -i '92c port 7000' /opt/bigdata/servers/redis-cluster/master4/bin/redis.conf
[root@linux01 redis-cluster]$ sed -i '92c port 7001' /opt/bigdata/servers/redis-cluster/slaver4/bin/redis.conf

编辑起服务脚本
