三主三从安装

环境 centos6.5
Redis1 172.16.5.1
Redis2 172.16.5.2
Redis3 172.16.5.3

• 关闭防火墙，selinux

chkconfig iptables off
vim /etc/selinux/config    disabled
reboot

• 配置yum源

• 安装包路径 /data

• 软件包
  openssl-1.0.2j.tar.gz redis-3.0.7.tar.gz redis-3.0.7.gem ruby-2.1.10.tar.gz rubygems-2.6.8.zip

• 安装路径 /ane
  所有节点镜像安装

tar -xf redis-3.0.7.tar.gz
cd redis-3.0.7
make
make install PREFIX=/ane/redis-3.0.7
ln -s /ane/redis-3.0.7 /ane/redis
mkdir /ane/redis/conf
mkdir /ane/redis/log
mkdir /ane/redis/data
mkdir /ane/redis/data/6379
mkdir /ane/redis/data/6380

修改系统参数

• 自改最大可打开文件数

vim /etc/security/limits.conf
soft nofile 102400
hard nofile 102400

echo "net.core.somaxconn = 2048" >> /etc/sysctl.conf
echo "vm.overcommit_memory = 1" >> /etc/sysctl.conf 
echo never > /sys/kernel/mm/transparent_hugepage/enabled
echo "fs.file-max = 65535" >> /etc/sysctl.conf
echo "net.core.somaxconn = 32767" >> /etc/sysctl.conf
sysctl -p

查看OOM是否为0如果不是，参照net.core.somaxconn修改
cat /proc/sys/vm/overcommit_memory
0

echo never > /sys/kernel/mm/transparent_hugepage/enabled追加到/etc/rc.local

拷贝配置文件

cp /data/redis-3.0.7/redis-conf /ane/redis/conf/redis-6379.conf 
cp /data/redis-3.0.7/redis-conf /ane/redis/conf/redis-6380.conf

创建集群

redis-trib.rb create --replicas 1 172.16.5.1:6379 172.16.5.2:6379 172.16.5.3:6379 172.16.5.1:6380 172.16.5.2:6380 172.16.5.3:6380

验证

[root@redis1 ~]# redis-cli -c -p 6379
127.0.0.1:6379> set a 1
-> Redirected to slot [15495] located at 172.16.5.3:6379
OK

[root@redis3 ~]# redis-cli -c -p 6379
