Yum 安装方式 - 推荐

# yum -y install https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
# yum -y install https://rpms.remirepo.net/enterprise/remi-release-7.rpm
# yum-config-manager --enable remi
# yum install -y redis
# systemctl enable redis && sudo systemctl start redis

编译安装方式 - 可选

# wget http://download.redis.io/releases/redis-5.0.7.tar.gz
# tar -zxvf redis-5.0.7.tar.gz -C /usr/local
# mv redis-5.0.7/ redis
# cd redis/
# make MALLOC=libc
# cd src && make install

• 修改redis.conf，服务器安装一点注意修改redis连接密码

# vim /usr/local/redis/redis.conf

# 修改对应配置值
bind 0.0.0.0 # Redis默认localhost访问，修改后可远程连接
protected-mode no
daemonize no
requirepass yourpassword #添加此项，设置redis连接密码，服务器必须设置

• 设置软链接

# ln -s /usr/local/redis/src/redis-server /usr/bin/redis-server
# ln -s /usr/local/redis/src/redis-sentinel /usr/bin/redis-sentinel

• 启动redis

# nohup redis-server /usr/local/redis/redis.conf &

• 启动哨兵模式

# nohup redis-sentinel /usr/local/redis/sentinel.conf &

• 设置 redis 开机自启动
• 在/etc目录下新建redis目录

# mkdir redis

• 将/usr/local/redis/redis.conf 文件复制一份到/etc/redis目录下，并命名为6379.conf

# cp /usr/local/redis/redis.conf /etc/redis/6379.conf

• 将redis的启动脚本复制一份放到/etc/init.d目录下

# cp /usr/local/redis/utils/redis_init_script /etc/init.d/redisd

• 切换到/etc/init.d目录下，执行自启命令

# chkconfig redisd on

• 启动 Redis

# service redisd start

若出现：service redisd does not support chkconfig
使用vim编辑redisd文件，在第一行加入如下两行注释，保存退出

# vim /etc/init.d/redisd

# chkconfig:   2345 90 10
# description:  Redis is a persistent key-value database
