redis集群环境修改端口(直接编辑自动生成的配置文件)

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.

计划修改redis每个节点的端口修改为如下

redis内部通信的端口是在redis内部通信端口上+10000,比如6379对应的内部端口就是16379

 

6379->6679
6380->6680
6381->6681
6382->6682
6383->6683
6384->6684

 

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 6679

 

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

 

cp 6379.conf bak_6379.conf
cp 6380.conf bak_6380.conf
cp 6381.conf bak_6381.conf
cp 6382.conf bak_6382.conf
cp 6383.conf bak_6383.conf
cp 6384.conf bak_6384.conf

 

[root@dev_test_redis redis_6379]# more bak_6379.conf

vars currentEpoch 6 lastVoteEpoch 0

修改为

[root@dev_test_redis redis_6379]# more 6379.conf 
f6e284c274d69367ba89116704b10c336dfa5824 192.168.1.84:6684@16684 slave 8d41f95b7447fe4e8f7c1c412e272e0803fe97b0 0 17

vars currentEpoch 6 lastVoteEpoch 0

 

注意redis内部通信端口也要修改(redis对外端口 + 10000) 

 

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
