Redis3.0.7集群安装部署
Redis集群没有出来前,一直使用Codis集群,现在部署Redis集群看看效果如何。
一,架构
Centos6.5 64位
redis1redis1:6379主redis3:6380从
redis2redis2:6379主redis1:6380从
redis3redis3:6379主redis2:6380从
二,部署Redis实例
1,安装依赖
yum -y install tcl-devel
2,下载
wget http://download.redis.io/releases/redis-3.0.7.tar.gz
3,编译
cd /usr/local/src/
tar zxvf redis-3.0.7.tar.gz
cd redis-3.0.7
make
4,测试
make test
5,安装二进制程序到/usr/local/bin/目录
make install
ls /usr/local/bin/ -lh
6,安装服务
sh ./utils/install_server.sh

警告
WARNING overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect.
7997:M 08 Dec 15:04:59.760 # WARNING you have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.
