Master:    192.168.174.201  
Slave: 192.168.174.202  
  
在两台服务器上面安装Redis，参考  
http://blog.itpub.net/26506993/viewspace-2146826/  
  
在主节点上，编辑配置文件  
\[root@MySQL01 redis-4.0.2\]\# vim redis.conf  
\# 指定端口  
port 6379

\# 配置密码   
requirepass abc  
  
\# 监听来自网络的所有连接  
\# bind 127.0.0.1

在从节点上，编辑配置文件  
  
\[root@localhost redis-4.0.2\]\# vim redis.conf  
\# 配置主节点的IP和端口  
slaveof 192.168.174.201 6379

\#  配置连接到 主库所使用 的密码   
masterauth abc  
  
\# 配置密码  
requirepass abc  
  
 \# 监听来自网络的所有连接   
\# bind 127.0.0.1  
  
 \# 指定端口   
port 6380

在主节点上，启动redis  
\[root@MySQL01 redis-4.0.2\]\# src/redis-server redis.conf   
51173:C 04 Nov 07:12:09.019 \# oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo  
51173:C 04 Nov 07:12:09.019 \# Redis version=4.0.2, bits=64, commit=00000000, modified=0, pid=51173, just started  
51173:C 04 Nov 07:12:09.019 \# Configuration loaded

在从节点上，启动redis  
\[root@localhost redis-4.0.2\]\# src/redis-server /opt/redis-4.0.2/redis.conf   
61391:C 04 Nov 07:14:10.695 \# oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo  
61391:C 04 Nov 07:14:10.695 \# Redis version=4.0.2, bits=64, commit=00000000, modified=0, pid=61391, just started  
61391:C 04 Nov 07:14:10.695 \# Configuration loaded

验证复制  
在主节点上面插入链表数据  
\[root@MySQL01 redis-4.0.2\]\# src/redis-cli -a abc  
127.0.0.1:6379> rpush list-key item1  
(integer) 1  
127.0.0.1:6379> rpush list-key item2  
(integer) 2  
127.0.0.1:6379> rpush list-key item3  
(integer) 3  
127.0.0.1:6379> lrange list-key 0 -1  
1) "item1"  
2) "item2"  
3) "item3"  
  
查看复制状态  
127.0.0.1:6379> info replication  
\# Replication  
role:master  
connected\_slaves:1  
slave0:ip=192.168.174.202,port=6380,state=online,offset=1785,lag=0  
master\_replid:17cc14861639f71ed1f82ce9999f22ff337014e4  
master\_replid2:0000000000000000000000000000000000000000  
master\_repl\_offset:1785  
second\_repl\_offset:-1  
repl\_backlog\_active:1  
repl\_backlog\_size:1048576  
repl\_backlog\_first\_byte\_offset:1  
repl\_backlog\_histlen:1785

在从节点上面查看链表数据

\[root@localhost redis-4.0.2\]\# src/redis-cli -h 192.168.174.202 -p 6380 -a abc  
192.168.174.202:6380> lrange list-key 0 -1  
1) "item1"  
2) "item2"  
3) "item3"  
  
查看复制状态
