redis6.0集群搭建

1. 解压编译

tar -zxcf redis-6.2.7.tar.gz
mv redis-6.2.7 redis
cd redis
sudo make && sudo make install

2. 修改配置文件redis.conf

sed -i 's/6379/7000/'  redis.conf 
sed -i 's/daemonize no/daemonize yes/'  redis.conf 
sed -i 's/protected-mode yes/protected-mode no/'  redis.conf 
sed -i 's/# cluster-enabled yes/ cluster-enabled yes/' redis.conf 

#sed -i 's/# cluster-config-file nodes-6379.conf/cluster-config-file nodes-7000.conf/'  redis.conf 
#sed -i 's:pidfile /var/run/redis_6379.pid:pidfile /data01/MPP/redisCluster/7000/redis_7000.pid:'   redis.conf 
# sed -i 's/#bind 127.0.0.1/bind 192.168.26.15 127.0.0.1/'  redis.conf 
# sed -i 's/dbfilename dump.rdb/dbfilename dump7000.rdb/'  redis.conf 
 
#修改或增加pid文件,bind,dir
pidfile /data01/MPP/redisCluster/redis_7000.pid
bind 192.168.26.15 127.0.0.1


#检查配置文件

cat redis.conf | grep "pidfile "
cat redis.conf | grep "daemonize "
cat redis.conf | grep "protected-mode"
cat redis.conf | grep "cluster-enabled"
cat redis.conf | grep "cluster-config-file "
cat redis.conf | grep "dbfilename "
cat redis.conf | grep "dir "
cat redis.conf | grep "bind "
cat redis.conf | grep "700"

#启动验证没问题就可以复制到其他节点上
/opt/MPP/redis/src/redis-server /data01/MPP/redisCluster/7000/redis.conf
/opt/MPP/redis/src/redis-cli -h 192.168.26.15 -p 7000 -c

3. 复制到指定主机上的目录

mkdir -p /data01/MPP/redisCluster/7000
mkdir -p /data01/MPP/redisCluster/7001

mkdir -p /data01/MPP/redisCluster/7002
mkdir -p /data01/MPP/redisCluster/7003
scp  /data01/MPP/redisCluster/7000/redis.conf  nbigdata2616:/data01/MPP/redisCluster/7002/
scp  /data01/MPP/redisCluster/7000/redis.conf  nbigdata2616:/data01/MPP/redisCluster/7003/

mkdir -p /data01/MPP/redisCluster/7004
mkdir -p /data01/MPP/redisCluster/7005
scp  /data01/MPP/redisCluster/7000/redis.conf  nbigdata2617:/data01/MPP/redisCluster/7004/
scp  /data01/MPP/redisCluster/7000/redis.conf  nbigdata2617:/data01/MPP/redisCluster/7005/

4. 根据情况替换ip和端口

#替换端口
cd /data01/MPP/redisCluster/7002/
sed -i 's/7000/7002/'  redis.conf 
#替换ip
sed -i 's/192.168.26.15/192.168.26.16/'  redis.conf 
sed -i 's/192.168.26.15/192.168.26.17/'  redis.conf 

5. 启动各节点

   /opt/MPP/redis/src/redis-server /data01/MPP/redisCluster/7000/redis.conf
   /opt/MPP/redis/src/redis-server /data01/MPP/redisCluster/7001/redis.conf

/opt/MPP/redis/src/redis-server /data01/MPP/redisCluster/7002/redis.conf
/opt/MPP/redis/src/redis-server /data01/MPP/redisCluster/7003/redis.conf

/opt/MPP/redis/src/redis-server /data01/MPP/redisCluster/7004/redis.conf
/opt/MPP/redis/src/redis-server /data01/MPP/redisCluster/7005/redis.conf

6. 组成集群

   /opt/MPP/redis/src/redis-cli --cluster create 192.168.26.15:7000 192.168.26.15:7001 192.168.26.16:7002 192.168.26.16:7003 192.168.26.17:7004 192.168.26.17:7005 --cluster-replicas 1

如果要给集群设置密码可以分别连上各个节点设置密码

#设置密码并使用rewrite永久写入配置文件
/opt/MPP/redis/src/redis-cli -h 192.168.26.15 -p 7000
config set masterauth "123456"
config set requirepass "123456"
auth "123456"
config rewrite
exit
