Redis单机安装和集群部署
一、Redis单机安装
注：本文安装Redis版本为redis-5.0.7
yum install -y gcc
wget http://download.redis.io/releases/redis-5.0.7.tar.gz
tar xzf redis-5.0.7.tar.gz
cd redis-5.0.7
make
mkdir -p /usr/local/redis/bin
cp src/redis-server /usr/local/redis/bin
cp src/redis-cli /usr/local/redis/bin
cp src/redis-sentinel /usr/local/redis/bin
cp src/redis-trib.rb /usr/local/redis/bin
cp src/redis-check-aof /usr/local/redis/bin
cp src/redis-check-rdb /usr/local/redis/bin
cp src/redis-benchmark /usr/local/redis/bin
echo 'export PATH=$PATH:/usr/local/redis/bin' >> .bash_profile
. .bash_profile
cp ./redis.conf /etc
二、修改Redis配置：
$ vim /etc/redis.conf
修改redis.conf中的以下内容：
bind 0.0.0.0 # 把 127.0.0.1 改为 0.0.0.0，监听所有 IPV4 地址，可以根据需求设置
daemonize yes # 把 no 修改为 yes，后台运行
三、启动Redis
启动redis服务：
$ redis-server /etc/redis.conf
验证redis是否启动成功：
$ redis-cli
127.0.0.1:6379>
127.0.0.1:6379> keys *
(empty list or set)
127.0.0.1:6379>
四、设置开机启动
vim /usr/lib/systemd/system/redis.service
[Unit]
Description=Redis Server
After=network.target
[Service]
Type=simple
# User=redis
# Group=redis
PIDFile=/var/run/redis.pid
ExecStart=/usr/local/redis/bin/redis-server /etc/redis.conf --daemonize no
# ExecStop=/usr/local/redis/bin/redis-cli shutdown
ExecStop=/usr/local/redis/bin/redis-cli -p 6379 shutdown
Restart=always
[Install]
WantedBy=multi-user.target
systemctl daemon-reload
systemctl start redis
systemctl enable redis
五、Redis集群部署
创建6个配置文件：
mkdir /etc/redis-cluster
cp redis.conf /etc/redis-cluster/redis-7001.conf
cp redis.conf /etc/redis-cluster/redis-7002.conf
cp redis.conf /etc/redis-cluster/redis-7003.conf
cp redis.conf /etc/redis-cluster/redis-7004.conf
cp redis.conf /etc/redis-cluster/redis-7005.conf
cp redis.conf /etc/redis-cluster/redis-7006.conf
mkdir /opt/redis-7001
mkdir /opt/redis-7002
mkdir /opt/redis-7003
mkdir /opt/redis-7004
mkdir /opt/redis-7005
mkdir /opt/redis-7006
修改所有的配置文件 （端口以及目录依次类推）

启动节点
redis-server /etc/redis-cluster/redis-7001.conf
redis-server /etc/redis-cluster/redis-7002.conf
redis-server /etc/redis-cluster/redis-7003.conf
redis-server /etc/redis-cluster/redis-7004.conf
redis-server /etc/redis-cluster/redis-7005.conf
redis-server /etc/redis-cluster/redis-7006.conf
创建集群
redis-cli --cluster create 192.168.223.111:7001 192.168.223.111:7002 192.168.223.111:7003 192.168.223.111:7004 192.168.223.111:7005 192.168.223.111:7006 --cluster-replicas 1
