Build a redis cluster in centos and a centosredis Cluster
Essential tools: redis-3.0.0.tarredis-3.0.0.gem (ruby and redis Interface) Analysis: first, the number of clusters requires a base, here to build a simple redis cluster (six redis instances for the cluster ). To operate on a server, you only need six different port numbers. They are: 7001, 7002, 7003, 7004, 7005. Step: 1. Upload redis-3.0.tarto the server (, decompress redis-3.0.0.tar. 2. Install the C language environment (after centos is installed, it comes with the C language environment) yuminstallgcc-c ++ 3, go to the redis-3.0.0 directory make4, install redis to the/usr/local/redis directory makeinstallPREFIX =/usr/local/redis5, check whether the installation is successful (the bin directory appears) 6. Start redis on the front end (enter the bin directory ). /redis-server (Enabled ). /redis-clishutdown7, back-end boot need to redis unzipping the source package (under the redis-3.0.0 directory) redis. copy the conf file to the bin directory and modify redis. conf file, change daemonize to yes first use vimredis. run the conf command to start the redisbin directory at the backend. /redis-serverredis.conf to check whether the boot is successful to close the way back-end boot: The above is a separate redis installation, then build the Cluster! Install rubyyuminstallrubyyuminstallrubygems upload the following files to the linux system and go to the directory for execution: The geminstallredis-3.0.0.gem copies the following files from the src directory under the redis-3.0.0 package to/usr/local/redis-cluster/prerequisites: creating a New redis-cluster directory requires at least three hosts to build a cluster. If each host is configured with another slave, at least six machines are required. The port design is as follows: Step 1: Copy A 7001 machine and run cpbin in the/usr/local/redis/directory. /redis-cluster/7001-r Step 2: If a persistent file exists, delete the rm-rfappendonly.aofdump.rdb Step 3: Set the cluster Parameters Step 4: Modify the port Step 5: copy the 7002-7006 host to show the directory structure under my desktop system: Next, set up one-click to start all redis or close the redis group: first, create a file and use vim to open a non-existent file, and then save it.
