redis主从配置

1.主节点安装部署
[root@localhost redis-4.0.14]# cd src
[root@localhost src]# make PREFIX=/opt/redis-master-slave/master install
[root@localhost src]# cp redis-trib.rb /opt/redis-master-slave/master/

2.创建目录并修改相应权限
[root@localhost src]# mkdir -p /opt/redis-master-slave/master/conf
[root@localhost src]# mkdir -p /opt/redis-master-slave/master/logs
[root@localhost src]# mkdir -p /opt/redis-master-slave/master/run
[root@localhost src]# mkdir -p /opt/redis-master-slave/master/data


3.从节点安装部署
[root@localhost redis-4.0.14]# cd src
[root@localhost src]# make PREFIX=/opt/redis-master-slave/slave install
[root@localhost src]# cp redis-trib.rb /opt/redis-master-slave/slave/


4.创建目录并修改相应权限
[root@localhost src]# mkdir -p /opt/redis-master-slave/slave/conf
[root@localhost src]# mkdir -p /opt/redis-master-slave/slave/logs
[root@localhost src]# mkdir -p /opt/redis-master-slave/slave/run
[root@localhost src]# mkdir -p /opt/redis-master-slave/slave/data



5.主从节点分别启动

/opt/redis-master-slave/master/bin/redis-server /opt/redis-master-slave/master/conf/7001.conf
从节点
/opt/redis-master-slave/slave/bin/redis-server /opt/redis-master-slave/slave/conf/7002.conf

6.验证
主库设置key
/opt/redis-master-slave/master/bin/redis-cli -h 192.168.1.85 -p 7001 -a hxlpasswd
192.168.1.85:7001> set name hxl

从库读取key
/opt/redis-master-slave/slave/bin/redis-cli -h 192.168.1.85 -p 7002 -a hxlpasswd
192.168.1.85:7002> get name
"hxl"

 

7.登陆从库查看配置信息

 

192.168.1.29:6379> info

说明:

主从环境下，若是将主库的rdb文件和aof文件删除掉(从库未删除)，那么主库重启动后，主从库的数据都会全部丢失,从库不会应用自己的aof和rdb文件
