安裝

# （三臺）安裝 C 語言需要的 GCC 環境
yum install -y gcc-c++ 
yum install -y wget
# 下載并解壓縮 Redis 源碼壓縮包
wget http://download.redis.io/releases/redis-5.0.5.tar.gz 
tar -zxf redis-5.0.5.tar.gz -C ../servers/
# 編譯 Redis 源碼，進入 redis-5.0.5 目錄，執行編譯命令
cd redis-5.0.5/src 
make
# 安裝 Redis ，需要通過 PREFIX 指定安裝路徑
mkdir /opt/bigdata/servers/redis-cluster/master1 -p 
make install PREFIX=/opt/bigdata/servers/redis-cluster/master1

注error：

# make 時 出現：
# 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，要求三主三從，記錄下安裝步驟

（2）能夠添加一主一從（Master4和Slaver4），記錄下安裝步驟

（3）能夠通過JedisCluster向RedisCluster添加數據和取出數據

解答

集群規劃

虛擬機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(準備添加主從)	master4 slaver4	7000 7001

編輯配置文件

# 1.拷貝conf文件到bin下
[root@linux02 redis-5.0.5]# cp redis.conf ../redis/bin/
# 2.編輯conf文件69 # bind 127.0.0.1		# 注掉bind 允許外界訪問
88 protected-mode no	# 將yes改成no，允許外界訪問
92 port 6379			# 端口號
136 daemonize yes		# 將no改成yes，允許后臺啟動
832 cluster-enabled yes	# 開啟cluster

分配啟動目錄

# 拷貝出從機
[root@linux01 redis-cluster]$ cp -r master1/ slaver1
# 修改 端口號
[root@linux01 ~]$ sed -i '92c port 6380' /opt/bigdata/servers/redis-cluster/slaver1/bin/redis.conf
# 查看 修改結果
[root@linux01 ~]$ sed -n '92p' /opt/bigdata/servers/redis-cluster/slaver1/bin/redis.conf
# 發送給 其他兩臺
[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/
# 修改名稱
[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/
# 準備 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
