redis sentinel 集群

##  实验在一台机器上允许，搭建redis一主两从，创建哨兵模式监控
##  整个脚本直接执行即可，确认ｒｏｏｔ权限执行

##  下载目录
mkdir /opt/soft
cd  /opt/soft
## 下载软件
wget  -O redis-2.8.22.tar.gz https://codeload.github.com/antirez/redis/tar.gz/2.8.22## 解压redis
tar -xf redis-2.8.22.tar.gz
cd redis-2.8.22
## 编译安装
make PREFIX=/usr/local/redis
make install PREFIX=/usr/local/redis
## 创建基本的目录，这里做1主两从6379是主，其它两个是从
mkdir -p /usr/local/redis/etc
cd /usr/local/redis/etc/
mkdir  -p /usr/local/redis/etc/6379

## 复制两份修改成从库分别用端口  6380  6381
scp    /usr/local/redis/etc/6379   /usr/local/redis/etc/6380
cd      /usr/local/redis/etc/6380
sed -i "s#6379#6380#g"   redis.conf
sed -i 's#26379#26380#'   sentinel.conf
echo 'slaveof 127.0.0.1 6379' >>  redis.conf

scp    /usr/local/redis/etc/6379   /usr/local/redis/etc/6381
cd       /usr/local/redis/etc/6381
sed -i "s#6379#6381#g"   redis.conf
sed -i 's#26379#26381#'   sentinel.conf
echo 'slaveof 127.0.0.1 6379' >>  redis.conf
### 到这里基本环境就搭建完成，现在启动环境
### 启动master
/usr/local/redis/bin/redis-server /usr/local/redis/etc/6379/redis.conf
###  启动两个从库
/usr/local/redis/bin/redis-server /usr/local/redis/etc/6380/redis.conf
/usr/local/redis/bin/redis-server /usr/local/redis/etc/6381/redis.conf
###  启动哨兵
/usr/local/redis/bin/redis-server /usr/local/redis/etc/6379/sentinel.conf
####  到这里安装完成
