一、单实例安装
1、安装依赖
yum install gcc-c++ yum install -y tcl yum install wget yum install vim
2、获取安装文件并解压安装
wget http://download.redis.io/releases/redis-3.2.8.tar.gz tar xzf redis-3.2.8.tar.gz cd redis-3.2.8 make make install
3、修改配置文件
vi redis.conf #1.设置为后台运行 daemonize no 改为 daemonize yes #2.修改默认端口 port 6379 改为 port 7963 #3.修改pidfile pidfile /var/run/redis_6379.pid 改为 pidfile /var/run/redis_7963.pid #4.设置日志级别 loglevel notice 改为 loglevel notice #5.修改日志文件路径 logfile "" 改为 logfile "/var/log/redis_7963.log" 复制配置文件到常用目录 mkdir -p /etc/redis/ cp redis.conf /etc/redis/redis_7963.conf
4、启动redis并连接测试
cd /etc/redis/ /usr/local/bin/redis-server redis_7963.conf /usr/local/bin/redis-cli -p 7963 127.0.0.1:7963> keys * (empty list or set) 127.0.0.1:7963> set test "hello redis" OK 127.0.0.1:7963> keys * 1) "test" 127.0.0.1:7963> get test "hello redis" 127.0.0.1:7963> del test (integer) 1 127.0.0.1:7963> keys * (empty list or set) 127.0.0.1:7963> exit
5、关闭Redis
#方案一： /usr/local/bin/redis-cli -p 7963 shutdown #方案二： netstat -lntp | grep 7963 #查看端口是否被占用 ps -ef|grep redis root 4726 1 0 10:33 ? 00:00:00 /usr/local/bin/redis-server 127.0.0.1:7963 root 4731 1253 0 10:40 pts/0 00:00:00 grep redis kill -9 4726 #备注说明：由于Redis可以接收并处理SIGTERM信号，所以直接使用kill -9 PID，是可以安全结束进程的； 另外：有两个信号可以停止进程，分别为：SIGTERM和SIGKILL SIGTERM用于提醒进程关闭，进程可以在关闭之前，结束打开的文件记录和完成正在进行的任务，如果有些任务不能中断，则可以忽略SIGTERM信号； SIGKILL则是强制关闭进程，即表示不管进程在做什么，应该马上关闭
6、设置开机启动
echo "/usr/local/bin/redis-server /etc/redis/redis_7963.conf" >> /etc/rc.local #注意：开机启动需要配置在rc.local中，而/etc/profile文件需要有用户登录才会被执行
二、单机多实例安装Cluster
1、创建集群需要的节点文件夹
mkdir -p /data/cluster/7000 mkdir -p /data/cluster/7001 mkdir -p /data/cluster/7003 mkdir -p /data/cluster/7004 mkdir -p /data/cluster/7002 mkdir -p /data/cluster/7005
2、创建配置文件
cd /data/cluster/7000 #复制配置文件 cp /etc/redis/redis_7963.conf redis.conf #修改配置文件 vim redis.conf port 7000 #设置端口号 daemonize yes #设置为后台运行 cluster-enabled yes #开启集群模式 cluster-config-file nodes.conf #节点配置文件路径 cluster-node-timeout 5000 #节点超时时间，单位：毫秒 appendonly yes #开启AOF持久化，防止数据在硬盘丢失 #复制配置文件，并修改端口号 cp redis.conf ../7001 cp redis.conf ../7002 cp redis.conf ../7003 cp redis.conf ../7004 cp redis.conf ../7005 vim ../7001/redis.conf vim ../7002/redis.conf vim ../7003/redis.conf vim ../7004/redis.conf vim ../7005/redis.conf
3、启动集群节点
redis-server redis.conf cd /data/cluster/7001 redis-server redis.conf cd /data/cluster/7002 redis-server redis.conf cd /data/cluster/7003 redis-server redis.conf cd /data/cluster/7004 redis-server redis.conf cd /data/cluster/7005 redis-server redis.conf #查看redis启动进程 ps -ef|grep redis root 1170 1 0 11:05 ? 00:00:32 /usr/local/bin/redis-server 127.0.0.1:7963 root 1311 1 0 16:16 ? 00:00:00 redis-server 127.0.0.1:7000 [cluster] root 1315 1 0 16:16 ? 00:00:00 redis-server 127.0.0.1:7001 [cluster] root 1319 1 0 16:16 ? 00:00:00 redis-server 127.0.0.1:7002 [cluster] root 1323 1 0 16:16 ? 00:00:00 redis-server 127.0.0.1:7003 [cluster] root 1327 1 0 16:16 ? 00:00:00 redis-server 127.0.0.1:7004 [cluster] root 1331 1 0 16:16 ? 00:00:00 redis-server 127.0.0.1:7005 [cluster] root 1338 1202 0 16:17 pts/0 00:00:00 grep redis
4、安装依赖并且创建集群
#安装ruby、rubygems yum install ruby rubygems -y #安装gem-redis cd /opt/ wget https://rubygems.org/downloads/redis-3.3.3.gem gem install -l redis-3.3.3.gem #复制管理程序 cp redis-3.2.8/src/redis-trib.rb /usr/local/bin/redis-trib #创建集群 redis-trib create --replicas 1 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 >>> Creating cluster >>> Performing hash slots allocation on 6 nodes...

5、测试集群节点写入
redis-cli -p 7000 127.0.0.1:7000> keys * (empty list or set) 127.0.0.1:7000> set test "hello redis cluster" (error) MOVED 6918 127.0.0.1:7001 127.0.0.1:7000> exit #7000，写入失败，换为7001进行写入测试 redis-cli -p 7001 127.0.0.1:7001> set test "hello redis cluster" OK 127.0.0.1:7001> keys * 1) "test" 127.0.0.1:7001> get test "hello redis cluster" 127.0.0.1:7001> exit
6、测试集群节点故障
