redis3.2.3 cluster configuration

Configure Redis cluster to two machines and 6 instances for the environment.

Operating system CentOS Linux release 7 64-bit

Install dependencies: Download Redis-3.3.1.gem separately this package will correspond to the OS version

Yum-y install tcl yum-y install ruby ruby-devel rubygems rpm-buildgem Install Redis

Unzip the installation:

Cd/usr/local/tar zxvf redis-3.2.3.tar.gzcd redis-3.2.3make && make install

Create a bin, redis6379, redis6380, redis6381 four directories under 172.16.25.220/usr/local/webapp

mkdir binmkdir Redis6379mkdir Redis6380mkdir redis6381

Create a bin, redis6379, redis6380, redis6381 four directories under 172.16.25.72/usr/local/webapp

mkdir binmkdir Redis6379mkdir Redis6380mkdir redis6381

Create the configuration file on both machines and start:

Create a cluster (execute on one of the servers)

Configure self-booting:

If configured as self-booting, then the relevant permissions will become root permissions, please consider carefully. The script from startup is given below for informational purposes only.

Under/ETC/INIT.D, write script redis6379 and give +x permissions, and then configure the boot level

Chkconfig--add redis6379

Chkconfig--level 345 redis6379 on

The script is as follows:
