#### 在项目中部署redis的读写分离架构(包含节点间认证口令)
##### 1、配置过程
---
1、此前就是已经将redis在系统中已经安装好了,redis utils目录下,有个redis_init_script脚本,将redis_init_script脚本拷贝到linux的/etc/init.d目录中,将redis_init_script重命名为redis_6379,6379是我们希望这个redis实例监听的端口号
2、创建两个目录:/etc/redis(存放redis的配置文件),/var/redis/6379(存放redis的持久化文件)
3、修改redis配置文件(默认在根目录下,redis.conf),拷贝到/etc/redis目录中,修改名称为6379.conf

4、此时修改redis中的redis.conf也就是

5、修改redis.conf中的部分配置为生产环境
(1)、daemonize yes 让redis以daemon进程运行

(2)、pidfile /var/run/redis_6379.pid 设置redis的pid文件位置

(3)、port 6379 设置redis的监听端口号

(4)、dir /var/redis/6379 设置持久化文件的存储位置

6、在redis_6379脚本中,最上面,加入两行注释
```
# chkconfig: 2345 90 10
# description: Redis is a persistent key-value database
```

7、chkconfig redis_6379 on
8、配置主从
(1)、在从机上进行配置
在slave node上配置:slaveof 192.168.1.1 6379,即可
###### replicaof <主机IP> <主机端口>

(2)、开启只读模式
###### replica-read-only yes
![image](https://img2018.cnblogs.com/blog/1334966/201910/1334966-20191013202748454-2135785897.png)
(3)、配置从机链接主机的口令
###### masterauth redis
![image](https://img2018.cnblogs.com/blog/1334966/201910/1334966-20191013202748615-1803917487.png)
(4)、配置主从机的bind地址
###### bind 192.168.1.124 (主机)
###### bind 192.168.1.125 (从机)
![image](https://img2018.cnblogs.com/blog/1334966/201910/1334966-20191013202748776-513750171.png)
(5)、配置主机的连接口令
###### requirepass redis
![image](https://img2018.cnblogs.com/blog/1334966/201910/1334966-20191013202749212-1774686242.png)
(6)、启动主机与从机的redis

(7)、连接主机与从机的redis
###### 主机
![image](https://img2018.cnblogs.com/blog/1334966/201910/1334966-20191013202749787-635850359.png)
###### 从机

(8)、测试主机加K - V

(9)、在从机查询
