redis cluster 4.0.9 之一: make make install

os: centos7.4
redis:4.0.9
ruby:2.3.4

ip 规划

redis1    192.168.56.101
redis2    192.168.56.102

用两台虚拟机模拟6个redis节点。
分别为
192.168.56.101 的 9001、9002、9003 端口，
192.168.56.102 的 9001、9002、9003 端口。

os安装

参考<<centos 7.x 安装 redis 的优化设置>>

使用 rvm 安装 ruby

下载、编译、安装

http://www.redis.cn/download.html
或者直接用wget
wget http://download.redis.io/releases/redis-4.0.9.tar.gz

redis1、redis2 两个节点都需要操作

# mkdir -p /usr/redis
# cd /usr/redis
# wget http://download.redis.io/releases/redis-4.0.9.tar.gz
# tar -zxvf ./redis-4.0.9.tar.gz
# cd redis-4.0.9
# make
# make test
# make install

执行 make install 后，会拷贝编译好的文件到 /usr/local/bin 目录下

# ls -l /usr/local/bin/
total 32748
-rwxr-xr-x 1 root root 4367368 May  8 12:01 redis-benchmark
-rwxr-xr-x 1 root root 8117952 May  8 12:01 redis-check-aof
-rwxr-xr-x 1 root root 8117952 May  8 12:01 redis-check-rdb
-rwxr-xr-x 1 root root 4807704 May  8 12:01 redis-cli
lrwxrwxrwx 1 root root      12 May  8 12:01 redis-sentinel -> redis-server
-rwxr-xr-x 1 root root 8117952 May  8 12:01 redis-server

redis1 节点上操作，创建 cluster data 目录

# mkdir -p /var/lib/redis/redis-cluster-data
# cd /var/lib/redis/redis-cluster-data
# mkdir -p 9001 9002 9003

redis2 节点上操作，创建 cluster data 目录

# mkdir -p /var/lib/redis/redis-cluster-data
# cd /var/lib/redis/redis-cluster-data
# mkdir -p 9001 9002 9003

redis1、redis2 两个节点都需要操作
创建bin目录，添加到PATH里

# cd /usr/redis/redis-4.0.9
# mkdir bin
# cd src
# cp mkreleasehdr.sh \
redis-benchmark \
redis-check-aof \
redis-check-rdb \
redis-cli redis-server \
redis-sentinel redis-trib.rb ../bin

# vi /etc/profile
PATH=/usr/redis/redis-4.0.9/bin:$PATH

# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin
# source /etc/profile
# echo $PATH
/usr/redis/redis-4.0.9/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin

redis cluster 配置

redis1 的 9001 9002 9003 目录下，
redis2 的 9001 9001 9003 目录下都需要创建 redis.conf

$ cd /var/lib/redis/redis-cluster-data/9001
$ vi redis.conf

redis.conf 配置文件请参考<<redis cluster 4.0.9 之七：redis.conf>>

正式创建

执行 redis-trib.rb 前必须安装ruby >= 2.2.2.

–replicas 1 代表每个master 有一个slave

# redis-trib.rb create --replicas 1 192.168.56.101:9001 192.168.56.101:9002 192.168.56.101:9003 192.168.56.102:9001 192.168.56.102:9002 192.168.56.102:9003
