Redis主从

复制2份redis.windows.conf配置文件，分别命名为redis.windows6380.conf和redis.windows6381.conf
修改配置

# redis.windows6380.conf如下：
port 6380
bind 127.0.0.1
slaveof 127.0.0.1 6379 # 设置master服务器为6379，如果不写这一段，也可以启动服务后，在连上服务器后执行slaveof 127.0.0.1 6379

# redis.windows6381.conf如下：
port 6381
bind 127.0.0.1
slaveof 127.0.0.1 6379 # 设置master服务器为6379

在这里插入图片描述
3. 启动服务
在redis安装目录下执行命令
redis-server.exe redis.windows.conf
redis-server.exe redis.windows6380.conf
redis-server.exe redis.windows6381.conf

4. 连接主Redis服务器
redis-cli -p 6379
5. 连接从Redis服务器
redis-cli -p 6380
注意只有主节点可以修改，从节点只读
在这里插入图片描述

Redis哨兵

和上面主从先一样启动6379、6380、6381三个服务
然后创建sentinel26379.conf文件，然后复制两份sentinel26380.conf、sentinel26381.conf

sentinel26379.conf文件内容

port 26379
#下面两行注释掉了，是因为低版本redis不支持这两个命令
#sentinel myid fad25e089080be8dddadd3f20e44f888b1f8d48a
#sentinel deny-scripts-reconfig yes
sentinel monitor mymaster 127.0.0.1 6379 2
sentinel down-after-milliseconds mymaster 10000
sentinel failover-timeout mymaster 15000

sentinel26380.conf文件内容

port 26380
#下面两行注释掉了，是因为低版本redis不支持这两个命令
#sentinel myid fad25e089080be8dddadd3f20e44f888b1f8d48b
#sentinel deny-scripts-reconfig yes
sentinel monitor mymaster 127.0.0.1 6379 2
sentinel down-after-milliseconds mymaster 10000
sentinel failover-timeout mymaster 15000

sentinel26381.conf文件内容

port 26381
#下面两行注释掉了，是因为低版本redis不支持这两个命令
#sentinel myid fad25e089080be8dddadd3f20e44f888b1f8d48c
#sentinel deny-scripts-reconfig yes
sentinel monitor mymaster 127.0.0.1 6379 2
sentinel down-after-milliseconds mymaster 10000
sentinel failover-timeout mymaster 15000

如果报下面的错，注释掉sentinel myid即可

D:\install\redis>redis-server.exe sentinel26379.conf --sentinel
Invalid argument during startup: Could not find sentinal subcommand myid

启动哨兵服务

redis-server.exe sentinel26379.conf --sentinel
redis-server.exe sentinel26380.conf --sentinel
redis-server.exe sentinel26381.conf --sentinel

关闭6379服务，查看主从变化

6379没关闭之前，在6380服务看master是6379

127.0.0.1:6380> info replication
# Replication
role:slave
master_host:127.0.0.1
master_port:6379
master_link_status:down
master_last_io_seconds_ago:-1
slave_repl_offset:36508
master_link_down_since_seconds:jd
slave_priority:100
slave_read_only:1
connected_slaves:0
master_repl_offset:0
repl_backlog_active:0
repl_backlog_size:1048576
repl_backlog_first_byte_offset:0
repl_backlog_histlen:0

关闭6379之后，可以看到master自动变成6381了

127.0.0.1:6380> info replication
# Replication
role:slave
master_host:127.0.0.1
master_port:6381
master_link_status:up
master_last_io_seconds_ago:0
master_sync_in_progress:0
slave_repl_offset:836
slave_priority:100
slave_read_only:1
connected_slaves:0
master_repl_offset:0
repl_backlog_active:0
repl_backlog_size:1048576
repl_backlog_first_byte_offset:0
repl_backlog_histlen:0

这个时候再重新启动6379,6379会自动变成6381的slave

D:\install\redis> redis-cli.exe -h 127.0.0.1 -p 6379
127.0.0.1:6379> info replication
# Replication
role:slave
master_host:127.0.0.1
master_port:6381
master_link_status:up
master_last_io_seconds_ago:0
master_sync_in_progress:0
slave_repl_offset:20949
slave_priority:100
slave_read_only:1
connected_slaves:0
master_repl_offset:0
repl_backlog_active:0
repl_backlog_size:1048576
repl_backlog_first_byte_offset:0
repl_backlog_histlen:0

Redis集群（cluster）

安装ruby环境

双击下载的“rubyinstaller-2.7.2-1-x64.exe”安装即可，同样，为了操作方便，也是建议安装在盘符根目录下，如： C:\Ruby27-x64 ，安装会默认把ruby添加到path环境变量

安装Ruby环境下Redis的驱动
将下载的"Ruby环境下Redis的驱动文件(redis-3.2.2.gem)"拷贝到Ruby安装根目录（C:\Ruby27-x64）下。

然后执行安装命令如下：

gem install --local C:/Ruby27-x64/redis-3.2.2.gem

将下载的“创建Redis集群的ruby脚本文件redis-trib.rb”文件拷贝到Redis安装根目录(D:\install\redis)下。
新建配置文件redis.windows-service-6380.conf
