redis集群自动生成的配置文件不能手工修改

环境:
OS:Centos 7
redis:4.0.14

 

1.当前集群的状态

[root@dev_test_redis redis_6384]# /usr/local/services/redis/bin/redis-cli -c -h 192.168.1.84 -p 6379 -a hxl2018
Warning: Using a password with '-a' option on the command line interface may not be safe.
192.168.1.84:6379> cluster nodes

计划修改redis每个节点的端口修改为如下:
6379->26379
6380->26380
6381->26381
6382->26382
6383->26383
6384->26384

 

2.停掉当前的集群
/usr/local/services/redis/bin/redis-cli -h 192.168.1.84 -a hxl2018 -p 6379 shutdown
/usr/local/services/redis/bin/redis-cli -h 192.168.1.84 -a hxl2018 -p 6380 shutdown
/usr/local/services/redis/bin/redis-cli -h 192.168.1.84 -a hxl2018 -p 6381 shutdown
/usr/local/services/redis/bin/redis-cli -h 192.168.1.84 -a hxl2018 -p 6382 shutdown
/usr/local/services/redis/bin/redis-cli -h 192.168.1.84 -a hxl2018 -p 6383 shutdown
/usr/local/services/redis/bin/redis-cli -h 192.168.1.84 -a hxl2018 -p 6384 shutdown

 

3.修改redis配置文件
对每个节点的配置文件进行修改,以其中一个节点为例子
vi /home/middle/redis_01/conf/6379.conf
port 26379

 

4.修改集群配置文件
集群配置文件存放在数据目录
[root@dev_test_redis redis_6379]# cd /home/middle/redis_01/data/redis_6379
[root@dev_test_redis redis_6379]# cp 6379.conf bak_6379.conf

 

[root@dev_test_redis redis_6379]# more 6379.conf 
8d41f95b7447fe4e8f7c1c412e272e0803fe97b0 192.168.1.84:6379@16379 myself,master - 0 1739428564000 1 connected 0-5460

修改为

[root@dev_test_redis redis_6379]# more 6379.conf 
8d41f95b7447fe4e8f7c1c412e272e0803fe97b0 192.168.1.84:26379@16379 myself,master - 0 1739428564000 1 connected 0-5460

5.启动集群
/usr/local/services/redis/bin/redis-server /home/middle/redis_01/conf/6379.conf
/usr/local/services/redis/bin/redis-server /home/middle/redis_01/conf/6380.conf
/usr/local/services/redis/bin/redis-server /home/middle/redis_01/conf/6381.conf
/usr/local/services/redis/bin/redis-server /home/middle/redis_01/conf/6382.conf
/usr/local/services/redis/bin/redis-server /home/middle/redis_01/conf/6383.conf
/usr/local/services/redis/bin/redis-server /home/middle/redis_01/conf/6384.conf

 

6.登录查看

/usr/local/services/redis/bin/redis-cli -c -h 192.168.1.84 -p 26379 -a hxl2018
192.168.1.84:26379> cluster info

好像是不行的.

 

7.恢复回去
停实例
/usr/local/services/redis/bin/redis-cli -h 192.168.1.84 -a hxl2018 -p 26379 shutdown
/usr/local/services/redis/bin/redis-cli -h 192.168.1.84 -a hxl2018 -p 26380 shutdown
/usr/local/services/redis/bin/redis-cli -h 192.168.1.84 -a hxl2018 -p 26381 shutdown
/usr/local/services/redis/bin/redis-cli -h 192.168.1.84 -a hxl2018 -p 26382 shutdown
/usr/local/services/redis/bin/redis-cli -h 192.168.1.84 -a hxl2018 -p 26383 shutdown
/usr/local/services/redis/bin/redis-cli -h 192.168.1.84 -a hxl2018 -p 26384 shutdown

修改配置文件,端口修改为原来的值,以其中一个实例为例
port 6379

 

还原集群配置文件,以6379端口实例为例
cd /home/middle/redis_01/data/redis_6379
mv bak_6379.conf 6379.conf

启动
/usr/local/services/redis/bin/redis-server /home/middle/redis_01/conf/6379.conf
/usr/local/services/redis/bin/redis-server /home/middle/redis_01/conf/6380.conf
