Redis 4.0主从复制配置是怎样的

本篇文章为大家展示了Redis 4.0主从复制配置是怎样的，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。

Master:    192.168.174.201
Slave: 192.168.174.202

在两台服务器上面安装Redis，

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

second_repl_offset:-1
repl_backlog_active:1
repl_backlog_size:1048576
repl_backlog_first_byte_offset:1

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"
