redis集群的安装部署

1.下载redis的稳定版本

wget https://download.redis.io/redis-stable.tar.gz

2..安装redis软件

tar -xzvf redis-stable.tar.gz
cd redis-stable
make
make install

编译过程中提示报错，需要安装gcc

3.编译配置文件

7001服务

4.启动服务

1.拷贝redis-server到服务目录
cd /opt/redis-cluster
 
cp /opt/redis-cluster/redis-stable/src/redis-server  7001
 
cp /opt/redis-cluster/redis-stable/src/redis-server  7002
 
cp /opt/redis-cluster/redis-stable/src/redis-server  7003
 
cp /opt/redis-cluster/redis-stable/src/redis-server  7004
 
cp /opt/redis-cluster/redis-stable/src/redis-server  7005
 
cp /opt/redis-cluster/redis-stable/src/redis-server  7006
 
2.启动服务
 
./redis-server redis-7001.conf
./redis-server redis-7002.conf 
./redis-server redis-7003.conf 
./redis-server redis-7004.conf 
./redis-server redis-7005.conf 
./redis-server redis-7006.conf 

5.安装集群所需的软件

yum install ruby rubygems -y
 
gem install redis 
 
升级rubygems gem
 
curl -sSL https://rvm.io/mpapis.asc | gpg2 --import -
curl -sSL https://get.rvm.io | bash -s stable
source /etc/profile.d/rvm.sh
rvm requirements
source /usr/local/rvm/scripts/rvm
 
rvm install 2.4.0
rvm use 2.4.0
 
gem install redis 
 
 
 
 

6.组建集群

cd /opt/redis-cluster/redis-stable/src
./redis-cli --cluster create 10.3.10.20:7001 10.3.10.20:7002 10.3.10.20:7003 10.3.10.20:7004 10.3.10.20:7005 10.3.10.20:7006 --cluster-replicas 1
 
 
 

集群输出如下

7.组建集群报错

[ERR] Node 10.3.10.20:7001 DENIED Redis is running in protected mode because protected mode is enabled and no password is set for the default user. In this mode connections are only accepted from the loopback interface. If you want to connect from exters to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SUREt publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and thg the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Setup a an authentication password for the default user. NOTE: You only need to do one of the above things in order for the servaccepting connections from the outside.

解决方式

在配置文件增加

masterauth "redis"
requirepass "redis"

重启redis进程

之后使用如下命令创建集群

./redis-cli --cluster create 10.3.10.20:7001 10.3.10.20:7002 10.3.10.20:7003 10.3.10.20:7004 10.3.10.20:7005 10.3.10.20:7006 --cluster-replicas 1 -a htjs 

8.集群验证

./redis-cli -c -h 10.3.10.20 -p 7001 -a htjs
