centos7安裝redis
1. yum 安裝
查看是否安裝了redis
yum installed list | grep redis
ps -ef | grep redis
安裝epel 倉(cāng)庫(kù)（倉(cāng)庫(kù)是軟件包下載的，類似maven，nuget）
yum install epel-release
搜索 redis 包
yum search redis
安裝：
yum install redis
查看配置：
rpm -ql redis
rpm -qc redis
rpm -qv redis
rpm -qi redis
卸載
yum install redis
# 查看是否卸載了
rpm -qi redis
上面是安裝的 3.x 太舊了，可用使用下面的方法安裝最新版：
yum -y update
yum -y install http://rpms.remirepo.net/enterprise/remi-release-7.rpm
yum --enablerepo=remi install redis
rpm -qi redis
配置
配置開機(jī)啟動(dòng):
systemctl enable --now redis
綁定IP，只允許本機(jī)訪問：
# 備份 /etc/redis.conf
# 打開 vi /etc/redis.conf
# 跳轉(zhuǎn)到66行：66gg
bind 127.0.0.1 ::1
# 配置密碼
requirepass 123456
# 重啟服務(wù)
systemctl restart redis
查看redis監(jiān)聽端口：
ss -tunelp | grep 6379
連接 redis
redis-cli
auth 123456
# 查看 redis 信息
info server
# 壓力測(cè)試
redis-benchmark -h 127.0.0.1 -p 6379 -n 10000 -c 15 -a 123456

卸載
yum remove redis
rpm -qi redis
手動(dòng)安裝
下載最新穩(wěn)定版：
cd /usr/local/
wget http://download.redis.io/releases/redis-7.2.4.tar.gz
# 解壓
tar -zxvf redis-7.2.4.tar.gz -C /usr/local/
# 安裝
cd /redis-7.2.4
make
make install
啟動(dòng) redis
# 啟動(dòng)
redis-server
# 后臺(tái)啟動(dòng)
nohup redis-server &
# 配置后臺(tái)啟動(dòng)
redis-server /usr/local/redis-7.2.4/redis.conf
配置開機(jī)自啟動(dòng)
# 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
重新加載：
systemctl daemon-reload
設(shè)置 redis 用戶和用戶組權(quán)限
useradd redis
mkdir /etc/redis
chown redis:redis /etc/redis
cp /usr/local/redis-7.2.4/redis.conf /etc/redis/redis.conf
# 設(shè)置開機(jī)啟動(dòng)服務(wù)
systemctl enable redis.service
處理報(bào)錯(cuò)，一開始直接用的root配置的，后來加了 redis 用戶，并且把配置移動(dòng)到 /etc/redis 后，解決。
