yum -y install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
yum --enablerepo=remi install redis
rpm -qi redis
配置
配置开机启动:
systemctl enable --now redis
绑定IP,只允许本机访问:
# 备份 /etc/redis.conf
# 打开 vi /etc/redis.conf
# 跳转到66行:66gg
bind 127.0.0.1 ::1
# 配置密码
requirepass 123456
# 重启服务
systemctl restart redis
查看redis监听端口:
ss -tunelp | grep 6379
连接 redis

rpm -qi redis
手动安装
下载最新稳定版:
cd /usr/local/
wget http://download.redis.io/releases/redis-7.2.4.tar.gz
# 解压
tar -zxvf redis-7.2.4.tar.gz -C /usr/local/
# 安装
cd /redis-7.2.4
make
make install
启动 redis
# 启动
redis-server
# 后台启动
nohup redis-server &
# 配置后台启动
redis-server /usr/local/redis-7.2.4/redis.conf
配置开机自启动
# vi /etc/systemd/system/redis.service
[Unit]
Description=redis-server
After=network.target
[Service]
User=redis
Group=redis
ExecStart=/usr/local/bin/redis-server /etc/redis/redis.conf
Restart=always
[Install]
WantedBy=multi-user.target
重新加载:
systemctl daemon-reload
设置 redis 用户和用户组权限
useradd redis
mkdir /etc/redis
chown redis:redis /etc/redis
cp /usr/local/redis-7.2.4/redis.conf /etc/redis/redis.conf
# 设置开机启动服务
systemctl enable redis.service
处理报错,一开始直接用的root配置的,后来加了 redis 用户,并且把配置移动到 /etc/redis 后,解决。
