redis集群单节点安装

创建redis目录

单节点启动redis级群

for ((i=1;i<=6;i++));do mkdir -p /data/redis/3160${i} /data/redis/env;done

以下全部在各节点执行------

拷贝公共配置文件redis-env.con 到6001~6002目录下，并修改端口和ip

ip=`ip add show eth0 | grep "scope global" |grep "brd" | awk '{ print $2}'|cut -d "/" -f1`

for ((i=1;i<=6;i++))
   do
        cp /data/redis/env/redis-env.conf /data/redis/3160${i}/redis.conf
        cp /data/redis/env/loggin.sh /data/redis/3160${i}/loggin.sh
        sed -i "s/6001/3160${i}/g" /data/redis/3160${i}/redis.conf
        sed -i "s/127.0.0.1/$ip/g" /data/redis/3160${i}/redis.conf
        sed -i "s/127.0.0.1/$ip/g" /data/redis/3160${i}/loggin.sh
        sed -i "s/port/3160${i}/g" /data/redis/3160${i}/loggin.sh
    done

下载编译安装redis

cd /usr/local
wget https://download.redis.io/releases/redis-5.0.13.tar.gz
tar -xvf redis-5.0.13.tar.gz
cd /usr/local/redis-5.0.13
yum install gcc g++ gcc-c++ make -y
make
make install

创建redis用户

groupadd redis
useradd -g redis -M redis
chown -R redis:redis /data/redis/
cat > /data/redis/start.sh<< EOF
for((i=1;i<=6;i++))
do /usr/local/redis-5.0.13/src/redis-server /data/redis/3160\$i/redis.conf &
sleep 1
done
EOF

创建集群修改ip为实际redis ip

cat > /data/redis/init_cluster<< EOF
/usr/local/redis-5.0.13/src/redis-cli --cluster create \$ip:31601 \$ip:31602 \$ip:31603 \$ip:31604 \$ip:31605 \$ip:31606 --cluster-replicas 1 -a admin@red353s
