redis单节点部署

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
