1、下载redis源文件，解压并安装
安装gcc tcl依赖
yum install -y gcc tcl
安装并验证
tar zxvf redis-4.0.6.tar.gz
cd redis-4.0.6/
make PREFIX=/usr/local/redis install
make test
出现"\o/ All tests passed without errors!"说明安装成功
程序做软连接到bin目录，方便直接执行
ln -s /usr/local/redis/bin/redis-cli /usr/local/bin/redis-cli
ln -s /usr/local/redis/bin/redis-sentinel /usr/local/bin/redis-sentinel
ln -s /usr/local/redis/bin/redis-server /usr/local/bin/redis-server
2、新增相关目录
注意要以非root用户运行redis服务，所以对应目录也要修改相应的拥有者
新增目录
mkdir /var/lib/redis/
mkdir /var/log/redis/
mkdir /var/run/redis/
mkdir /etc/redis/
新增redis用户并设置密码
groupadd redis
useradd -g redis redis
passwd redis
修改对应目录的拥有者
chown -R redis.redis /var/lib/redis/
chown -R redis.redis /var/log/redis/
chown -R redis.redis /var/run/redis/
chown -R redis.redis /etc/redis/
3、启动redis服务
su redis
redis-server /etc/redis/redis.conf
redis-sentinel /etc/redis/sentinel.conf &
查看服务状态
redis-cli -p 6481 -a password
redis-cli -p 26481 -a password
