wget http://download.redis.io/releases/redis-6.2.6.tar.gz
tar xf redis-6.2.6.tar.gz
cd redis-6.2.6/

编译安装

make PREFIX=/usr/local/redis6 install

如果编译提示jemallo文件不存在,清空make缓存重新编译
make distclea
make clean

配置

mkdir /usr/local/redis6/confcp redis.conf /usr/local/redis6/conf/mkdir -p /data/redis6/data
mkdir -p /data/redis6/logsvi /usr/local/redis6/conf/redis.conf#配置参数，其他默认
bind 0.0.0.0
protected-mode no
port 6379
daemonize yes
logfile "/data/redis6/logs/redis.log"
dir /data/redis6/data/
maxmemory 2048MB
io-threads 4

配置systemd

vi /lib/systemd/system/redis6.service
[Unit]
Description=Redis
After=network.target[Service]
Type=forking
PIDFile=/var/run/redis_6379.pid
ExecStart=/usr/local/redis6/bin/redis-server /usr/local/redis6/conf/redis.conf
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true[Install]
WantedBy=multi-user.target

服务启停及开机启动

systemctl daemon-reload 
systemctl start redis6
systemctl enable redis6

登录验证

ln -s /usr/local/redis6/bin/redis-cli /usr/bin/redis-cli
redis-cli -h 127.0.0.1 -p 6379 -a mh112233
set a 11
get a

主从同步

#从节点增加配置，ip指向主节点
replicaof 192.168.122.230 6379
#配置密码
masterauth mh112233#检查主从同步状态
info replication

配置哨兵

cp sentinel.conf /usr/local/redis6/conf/
mkdir -p /data/redis6/data/sentinelvi /usr/local/redis6/conf/sentinel.conf#配置参数，其他默认
bind 0.0.0.0
protected-mode no
port 26379
daemonize yes
logfile "/data/redis6/logs/sentinel.log"
dir /data/redis6/data/sentinel/#指定Redis主节点主机IP地址和端口，ip根据实际情况调整，mymaster这个名称随便取，下面配置时也需要指定这个名称，客户端连接时也会使用
#最后的2是指需要有2个以上sentinel节点认为redis主节点失效，才是真的失效，一般为（sentinel总数/2+1）
sentinel monitor mymaster 192.168.122.230 6379 2#配置连接密码，此处的密码需要与 redis.conf里面配置的连接密码一致
sentinel auth-pass mymaster mh112233
