How to configure redis installation and master-slave replication in CentoS environment

Dependent environment

centos 6.5
gcc-4.4.7: Compile redis original file
tcl-8.5.7: Run compilation detection

1. Compile redis

#cd /usr/local
#tar -zxvf redis-4.0.1.tar.gz
#mv redis-4.0.1 redis
#cd redis
#make

Running the compilation test make test requires tcl-8.5 and above

#yum install -y tcl
#make test

2. Start redis

#cd src
#./redis-server

3. Access redis

#cd ./redis-cli

It is recommended to install the latest version. When accessing on the Linux side, there are code format prompts for easy practice

>set name "redis"
>get name

4 .Master-slave replication

Deploy two redis services on one machine

#cd /usr/local

4.1. Create redis (master) with service port 6379

#mv redis redis-6379
#mkdir redis-6380

4.2. The service port is redis (slave) 6380

#cp -r redis-6379 redis-6380
#cd redis-6380

4.3. Change the port and set the ip and port of the main redis

#vi redis.conf
port=6380
slaveof 127.0.0.1 6379

4.4. Start the master redis first and then start the slave redis

# cd /usr/local/redis-6379/src
#./redis-server ../redis.conf
#cd /usr/local/redis-6380/src
#./redis-server ../redis.conf

4.5. Test the master-slave redis

#./redis-cli -p 6379
>set name "redis"
>get name
redis
>quit
#./redis-cli -p 6380
>get name
redis

tip : If you test redis master-slave replication between different servers, you need to note that the IP bound to redis needs to be changed to an open-access IP (127.0.0.1—>192.168.2.134), and the port also needs to be open in the firewall
