Linux安裝Redis主從

下載2.8.17版本

$ wget http://download.redis.io/releases/redis-2.8.17.tar.gz
$ tar xzf redis-2.8.17.tar.gz
$ cd redis-2.8.17

make

$ yum -y install gcc automake autoconf libtool make   #【也許在make以前要先安裝GCC】
$ make MALLOC=libc

構造redis目錄、複製文件

$ mkdir -p ../redis_ms/redis_6380/src
$ mkdir -p ../redis_ms/redis_6381/src
$ mkdir -p ../redis_ms/redis_6382/src
$ cp runtest runtest-sentinel redis.conf sentinel.conf ../redis_ms/redis_6380
$ cp runtest runtest-sentinel redis.conf sentinel.conf ../redis_ms/redis_6381
$ cp runtest runtest-sentinel redis.conf sentinel.conf ../redis_ms/redis_6382
$ cd src/
$ cp redis-benchmark redis-check-aof redis-check-dump redis-cli redis-sentinel redis-server ../../redis_ms/redis_6380/src/
$ cp redis-benchmark redis-check-aof redis-check-dump redis-cli redis-sentinel redis-server ../../redis_ms/redis_6381/src/
$ cp redis-benchmark redis-check-aof redis-check-dump redis-cli redis-sentinel redis-server ../../redis_ms/redis_6382/src/
$ cd ../../redis_ms/

編輯節點配置
