二，具体搭建过程（上述配置可以直接用于redis-sentinel集群使用）

1，搭建redis master

cd /usr/local/src

wget http://download.redis.io/releases/redis-3.0.7.tar.gz

tar -zxvf redis-3.0.7.tar.gz

cd redis-3.0.7

make

make PREFIX=/usr/local/redis-3.0.7 install

ln -s /usr/local/redis-3.0.7 /usr/local/redis

mkdir -p /usr/local/redis/conf

cp redis.conf /usr/local/redis/conf/6379.conf  (这里可以直接用上面的master配置文件)

mkdir -p /usr/local/redis/data

mkdir -p /usr/local/redis/logs

注：

#为防止启动redis的时候，有警告信息，所以提前修改参数。

echo 'net.core.somaxconn= 2048' >> /etc/sysctl.conf

#这个配置和tcp-backlog有联系，但是tcp-backlog不能大于它。

echo 'vm.overcommit_memory = 1' >> /etc/sysctl.conf
echo never > /sys/kernel/mm/transparent_hugepage/enabled
sysctl -p

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

上述master端安装完毕，启动master端。

cd /usr/local/redis/bin/

./redis-server ../conf/6379.conf

2， master安装完成后，安装slave1端，我这里有2个slave端，基本上和master配置一样。slave端有明确的slave of master_ip master_port配置。

cd /usr/local/redis/conf

touch 6380.conf  ，可以直接使用上slave1上的配置内容.

启动redis salve1节点。

cd /usr/local/redis/bin

./redis-server ../conf/6380.conf

3, 安装slave2，操作一样，省略..

cd cd /usr/local/redis/bin

./redis-server ../conf/6381.conf

4，基本上，redis主从搭建完毕，确认一下主从同步是否成功。

设置key，查看是否获取成功。

以上，表示redis主从搭建完毕。
