redis主从架构

1、环境

2、分别部署redis

我已经提前准备好了，具体步骤看我另一个博客

https://www.cnblogs.com/hsyw/p/13254117.html

3、主从配置文件更改

3.1、在188上更改配置文件（新增的，其他的都没改）

#从服务器连接密码
masterauth "tzh"
#cli连接密码
requirepass 123456

3.2、在189上操作（新增的，其他的都没改）

#配置主服务器的ip 端口
slaveof 192.168.47.188 6379
#配置主服务器的密码
masterauth 123456

4、启动

#启动主服务器
[root@t1 bin]# pwd
/app/redis/bin
[root@t1 bin]# ./redis-server ../conf/redis.conf
#启动主服务器
[root@t2 bin]# pwd
/app/redis/bin
[root@t2 bin]# ./redis-server ../conf/redis.conf

5、验证、测试

5.1、验证

#在主服务器上，输入连接密码
[root@t1 bin]# ./redis-cli 
127.0.0.1:6379> AUTH 123456
OK
127.0.0.1:6379> info replication
# Replication
role:master  #这是主服务器master
connected_slaves:1  #成功连接slave服务器的数量
slave0:ip=192.168.47.189,port=6379,state=online,offset=1691,lag=1  #slave服务器的信息
master_replid:f60d4b3d8b8f295491af42a3f57a7e59a8f60f7e
master_replid2:0000000000000000000000000000000000000000
master_repl_offset:1691
second_repl_offset:-1
repl_backlog_active:1
repl_backlog_size:1048576
repl_backlog_first_byte_offset:1
repl_backlog_histlen:169
?
#在从服务器连接
127.0.0.1:6379> INFO  replication
# Replication
role:slave  #这是一台slave服务器
master_host:192.168.47.188   #主服务器端ip地址
master_port:6379             #主服务器端口号
master_link_status:up        #连接状态
master_last_io_seconds_ago:7
master_sync_in_progress:0
slave_repl_offset:1943
slave_priority:100
slave_read_only:1           #成为slave服务器后，只读。不能set 只能get
connected_slaves:0
master_replid:f60d4b3d8b8f295491af42a3f57a7e59a8f60f7e
master_replid2:0000000000000000000000000000000000000000
master_repl_offset:1943
second_repl_offset:-1
repl_backlog_active:1
repl_backlog_size:1048576
repl_backlog_first_byte_offset:1
repl_backlog_histlen:1943

5.2、测试

#在主服务器上
127.0.0.1:6379> set test 123
OK
#在从服务器上
127.0.0.1:6379> get test
"123"
#说明可以主从搭建成功。有空在更新个哨兵模式，也很简单。在再一台服务器，增加个哨兵就可以了。
