准备一台机器，系统版本为CentOS7。
部署redis
1、下载软件包
1 wget http://download.redis.io/releases/redis-3.2.8.tar.gz
2、解压
1 tar xvf redis-3.2.8.tar.gz -C /usr/local/ 2 cd /usr/local/ 3 ln -sv redis-3.2.8/ redis
3、编译
1 yum groupinstall -y "Development Tools" 2 cd redis 3 make
4、为多实例redis配置启动环境
1 mkdir -pv /home/redis-cluster/{9000,9001,9002} 2 3 cp src/{redis-server,redis-sentinel} /home/redis-cluster/9000/ 4 cp src/{redis-server,redis-sentinel} /home/redis-cluster/9001/ 5 cp src/{redis-server,redis-sentinel} /home/redis-cluster/9002/ 6 7 cp redis.conf sentinel.conf /home/redis-cluster/9000/ 8 cp redis.conf sentinel.conf /home/redis-cluster/9001/ 9 cp redis.conf sentinel.conf /home/redis-cluster/9002/
5、修改配置文件
# vim /home/redis-cluster/9000/redis.conf bind 172.60.0.170 protected-mode no port 9000 daemonize yes appendonly yes # cp /home/redis-cluster/9000/redis.conf /home/redis-cluster/9001/redis.conf # cp /home/redis-cluster/9000/redis.conf /home/redis-cluster/9002/redis.conf # vim /home/redis-cluster/9001/redis.conf port 9001 slaveof 172.60.0.170 9000 # vim /home/redis-cluster/9002/redis.conf port 9002 slaveof 172.60.0.170 9000
6、启动三个redis实例
# cd /home/redis-cluster/9000/ # ./redis-server redis.conf # cd ../9001/ # ./redis-server redis.conf # cd ../9002/ # ./redis-server redis.conf # ps -ef | grep redis root 23565 1 0 03:29 ? 00:00:03 ./redis-server 172.60.0.170:9000 root 23569 1 0 03:29 ? 00:00:02 ./redis-server 172.60.0.170:9001 root 23575 1 0 03:29 ? 00:00:02 ./redis-server 172.60.0.170:9002
7、验证，查看主从状态
# /usr/local/redis/src/redis-cli -h 172.60.0.170 -p 9000 172.60.0.170:9000> set name keith OK 172.60.0.170:9000> get name "keith" 172.60.0.170:9000> info replication # Replication role:master connected_slaves:2 slave0:ip=172.60.0.170,port=9001,state=online,offset=99,lag=1 slave1:ip=172.60.0.170,port=9002,state=online,offset=99,lag=0 master_repl_offset:99 repl_backlog_active:1 repl_backlog_size:1048576 repl_backlog_first_byte_offset:2 repl_backlog_histlen:98
部署sentinel
1、部署实例一
1 # cd /home/redis-cluster/9000 2 # vim sentinel.conf 3 protected-mode no 4 port 29000 5 daemonize yes 6 dir /home/redis-cluster/9000/logs 7 sentinel monitor mymaster 172.60.0.170 9000 2 8 # mkdir logs 9 # ./redis-sentinel sentinel.conf 10 # cp sentinel.conf ../9001/ 11 # cp sentinel.conf ../9002/
2、部署实例二
1 # cd ../9001/ 2 port 29001 3 dir "/home/redis-cluster/9001/logs" 4 # mkdir logs 5 # ./redis-sentinel sentinel.conf
3、部署实例三
1 # cd ../9002/ 2 # vim sentinel.conf 3 port 29002 4 dir "/home/redis-cluster/9002/logs" 5 # mkdir logs 6 # ./redis-sentinel sentinel.conf 7 # ps -ef | grep redis 8 root 23565 1 0 03:29 ? 00:00:03 ./redis-server 172.60.0.170:9000 9 root 23569 1 0 03:29 ? 00:00:03 ./redis-server 172.60.0.170:9001 10 root 23575 1 0 03:29 ? 00:00:03 ./redis-server 172.60.0.170:9002 11 root 23923 1 0 03:43 ? 00:00:04 ./redis-sentinel *:29000 [sentinel] 12 root 23927 1 0 03:44 ? 00:00:04 ./redis-sentinel *:29001 [sentinel] 13 root 23965 1 0 03:44 ? 00:00:04 ./redis-sentinel *:29002 [sentinel]
4、验证
# /usr/local/redis/src/redis-cli -h 172.60.0.170 -p 29000
