二，具體搭建過程（上述配置能夠直接用於redis-sentinel集羣使用）

 

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  (這裏能夠直接用上面的master配置文件)

mkdir -p /usr/local/redis/data

mkdir -p /usr/local/redis/logs



注：

#爲防止啓動redis的時候，有警告信息，因此提早修改參數。

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

#這個配置和tcp-backlog有聯繫，可是tcp-backlog不能大於它。

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端安裝完畢，啓動master端。

 

cd /usr/local/redis/bin/  

./redis-server ../conf/6379.conf 

 

 

2， master安裝完成後，安裝slave1端，我這裏有2個slave端，基本上和master配置同樣。slave端有明確的slave of master_ip master_port配置。

cd /usr/local/redis/conf

touch 6380.conf  ，能夠直接使用上slave1上的配置內容.

啓動redis salve1節點。

 

cd /usr/local/redis/bin

./redis-server ../conf/6380.conf 

 

3, 安裝slave2，操做同樣，省略..

cd cd /usr/local/redis/bin

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

 

 

4，基本上，redis主從搭建完畢，確認一下主從同步是否成功。

 

 

 

 設置key，查看是否獲取成功。

 

 

以上，表示redis主從搭建完畢。
