【Redis】【22】单机 Redis5.0集群安装

1.单机安装redis5.0

yum install gcc tcl -y

cd /usr/local/src && wget https://download.redis.io/releases/redis-5.0.10.tar.gz
使用迅雷下载很快

tar -zxvf redis-5.0.10.tar.gz ../

cd /usr/local/src/redis-5.0.10 && make insatll

vim /usr/local/src/redis-5.0.10/redis.conf

修改配置
daemonize yes
#注释此条只能本机的客户端连接,使外网可以访问
#bind 127.0.0.1

启动
/usr/local/src/redis-5.0.10/src/redis-server redis.conf

查看
ps -ef|grep redis

进入客户端
/usr/local/src/redis-5.0.10/src/redis-cli

退出
quit

2.创建集群文件夹，修改配置

1.mkdir /usr/local/redis-cluster/ && cd /usr/local/redis-cluster/
mkdir 6001 6002 6003 6004 6005 6006 6007 6008

cp /usr/local/redis-5.0.10/redis.conf /usr/local/redis-cluster/6001/

vim /usr/local/redis-cluster/6001/redis.conf

#注释此条只能本机的客户端连接,使外网可以访问
#bind 127.0.0.1

# 将 protected-mode yes 改为 protected-mode no,关闭安全模式,使外网可以访问
protected-mode yes 改为 protected-mode no #关闭安全模式

#修改端口 port 6379 为port 6001
port 6001

#后台启动模式
daemonize yes

#修改pid
pidfile /var/run/redis_6001.pid

#数据文件的位置
dir  /usr/local/redis-cluster/6001/

#使用密码
# requirepass foobared 
requirepass xxx

appendonly yes

cluster-enabled yes

cluster-config-file nodes-6001.conf

cluster-node-timeout 5000

masterauth xxx

cp /usr/local/redis-cluster/6001/redis.conf /usr/local/redis-cluster/6002
sed -i "s/6001/6002/g" `grep "6001" -rl /usr/local/redis-cluster/6002`

cp /usr/local/redis-cluster/6001/redis.conf /usr/local/redis-cluster/6003
sed -i "s/6001/6003/g" `grep "6001" -rl /usr/local/redis-cluster/6003`

cp /usr/local/redis-cluster/6001/redis.conf /usr/local/redis-cluster/6004
sed -i "s/6001/6004/g" `grep "6001" -rl /usr/local/redis-cluster/6004`

cp /usr/local/redis-cluster/6001/redis.conf /usr/local/redis-cluster/6005
sed -i "s/6001/6005/g" `grep "6001" -rl /usr/local/redis-cluster/6005`

cp /usr/local/redis-cluster/6001/redis.conf /usr/local/redis-cluster/6006
sed -i "s/6001/6006/g" `grep "6001" -rl /usr/local/redis-cluster/6006`

cp /usr/local/redis-cluster/6001/redis.conf /usr/local/redis-cluster/6007
sed -i "s/6001/6007/g" `grep "6001" -rl /usr/local/redis-cluster/6007`

cp /usr/local/redis-cluster/6001/redis.conf /usr/local/redis-cluster/6008
sed -i "s/6001/6008/g" `grep "6001" -rl /usr/local/redis-cluster/6008`

3.启动

/usr/local/redis-5.0.10/src/redis-server /usr/local/redis-cluster/6001/redis.conf
/usr/local/redis-5.0.10/src/redis-server /usr/local/redis-cluster/6002/redis.conf
/usr/local/redis-5.0.10/src/redis-server /usr/local/redis-cluster/6003/redis.conf
/usr/local/redis-5.0.10/src/redis-server /usr/local/redis-cluster/6004/redis.conf
/usr/local/redis-5.0.10/src/redis-server /usr/local/redis-cluster/6005/redis.conf
/usr/local/redis-5.0.10/src/redis-server /usr/local/redis-cluster/6006/redis.conf

ps -ef|grep redis

4.创建集群

/usr/local/redis-5.0.10/src/redis-cli -h
  --cluster <command> [args...] [opts...]
       Cluster Manager command and arguments (see below).


/usr/local/redis-5.0.10/src/redis-cli --cluster help 
Cluster Manager Commands:
  create         host1:port1 ... hostN:portN
                 --cluster-replicas <arg>

启动
/usr/local/redis-5.0.10/src/redis-cli -a xxx --cluster create --cluster-replicas 1 172.21.0.13:6001  172.21.0.13:6002 172.21.0.13:6003 172.21.0.13:6004 172.21.0.13:6005 172.21.0.13:6006

yes

5.连接集群 -c表示集群

/usr/local/redis-5.0.10/src/redis-cli -a xxx -c -p 6001 

6.验证集群信息
