CentOS 7.3 Sentinel实现Redis集群高可用部署

三台机器：
10.149.151.81    master/Sentinel
10.149.151.82    slave1/Sentinel
10.149.151.83    slave2/Sentinel
一、初始化系统环境(三台均需操作)
echo "vm.overcommit_memory = 1"  >> /etc/sysctl.conf
sysctl -p
echo 1024 > /proc/sys/net/core/somaxconn
mkdir /data/redis/logs/ -p
mkdir /data/redis/rdb/ -p

二、redis的安装和配置文件统一修改
1.安装：
cd /usr/src/
wget http://download.redis.io/releases/redis-3.2.6.tar.gz
tar zxf redis-3.2.6.tar.gz
cd redis-3.2.6
make
make PREFIX=/usr/local/redis install
cat < /etc/profile.d/redis.sh
export PATH=$PATH:/usr/local/redis/bin/
EOF
source /etc/profile.d/redis.sh
cp redis.conf /etc/
cp sentinel.conf /etc/

3.三台机器配置sentinel.conf
port 26379
daemonize yes
protected-mode no
dir "/data/redis/logs"
logfile "sentinel.log"

sentinel monitor mymaster 10.149.151.81 6379 2

4.启动redis，sentinel
master启动redis：
redis-server /etc/redis.conf &
三台均启动sentinel：
redis-sentinel /etc/sentinel.conf &
slave依次启动redis：
redis-server /etc/redis.conf &
5.验证：
连接：
redis-cli -h 10.149.151.81 -a 123456aa
查看信息：
info Replication
6.附命令：
停止redis：
redis-cli -h 10.149.151.81 -a 123456aa shutdown
