Installation environment centos7 ip: 192.168.5.181
1. Download the installation package
Address: wget http://download.redis.io/releases/redis-3.2.8.tar.gz
2. Unzip, compile and install
tar xzf redis-3.2.8.tar.gz cd redis-3.2.8 make && make install
3. Create a startup instance
cd /root
mkdir -p redis_cluster/6001
#Create a file
vi redis.conf
#The content is as follows:
bind 192.168.5.181
daemonize yes
port 6001
pidfile /var/run/redis_6001.pid
cluster-enabled yes
cluster-config-file nodes_6001.conf
cluster-node-timeout 6000
appendonly yes
mkdir -p redis_cluster/6002
#Create a file
vi redis.conf
#The content is as follows:
bind 192.168.5.181
daemonize yes
port 6002
pidfile /var/run/redis_6002.pid
cluster-enabled yes
cluster-config-file nodes_6002.conf
cluster-node-timeout 6000
appendonly yes
#Create 6003, 6004, 6005, 6006 in sequence The same as the above creation method, omitted here...
#Create a startup script:
cd /root/redis_cluster
vi start_all.sh
#The content is as follows
cd 6001
redis-server 6001/redis.conf
cd ../6002
redis-server 6002/redis.conf
cd ../6003
redis-server 6003/redis.conf
cd ../6004
redis-server 6004/redis.conf
cd ../6005
redis-server 6005/redis.conf
cd ../6006
redis-server 6006/redis.conf
chmod +x start_all.sh
./start_all.sh
View the redis process:
ps -ef | grep redis
The result is as follows
root 16623 1 0 16:19 ? 00:00:00 redis-server 127.0.0.1:6001 [cluster] root 16625 1 0 16:19 ? 00:00:00 redis-server 127.0.0.1:6002 [cluster] root 16629 1 0 16:19 ? 00:00:00 redis-server 127.0.0.1:6003 [cluster] root 16631 1 0 16:19 ? 00:00:00 redis-server 127.0.0.1:6004 [cluster] root 19355 1 0 16:24 ? 00:00:00 redis-server 127.0.0.1:6005 [cluster] root 19398 1 0 16:24 ? 00:00:00 redis-server 127.0.0.1:6006 [cluster]
4. Use redis-trib.rb to create a redis cluster
Install the redis-trib.rb runtime environment ruby
yum -y install ruby ruby-devel rubygems rpm-build
It takes about 30 seconds to install ruby's redis interface
gem install redis cd /root/src/redis-3.2.8/src cp redis-trib.rb /root/redis_cluster
Make a startup script and start
vi start_cluster.sh #content redis-trib.rb create --replicas 1 192.168.5.181:6001 192.168.5.181:6002 192.168.5.181:6003 192.168.5.181:6004 192.168.5.181:6005 192.168.5.181:6006 chmod +x start_cluster.sh ./start_cluster.sh
If there is no error in the startup, and the installation is successful
5. Test redis-cluster
Check the current status of the cluster:
redis-cli -c -p 6001 127.0.0.1:6001> cluster info
Test the stored value:
127.0.0.1:6001> set niaho hello 127.0.0.1:6001> get nihao
