正常搭建集羣后,使用時發現ip變成內網。
解決方案:
1.殺死節點(不是停止集羣,否則不生效)
2.找到所有節點的nodes.conf文件,把內網地址改成你的ip
3.重啓節點 ./redis-server redis.conf
二、redis集羣搭建:
1.CentOs命令如下:
wget http://download.redis.io/releases/redis-5.0.5.tar.gz
tar xzf redis-5.0.5.tar.gz
cd redis-5.0.5
yum install gcc
make MALLOC=libc
cd src && make install
cd ../utils/create-cluster/
ps -ef|grep redis
vim create-cluster
2.修改create-cluster配置文件:
注:(以下這幾點必須弄,否則阿里雲公網節點間切換不正常)
2.1. start命令: 加入redis密碼 --requirepass 88888888
關閉安全模式(公網可以連接到redis) --protected-mode no
2.2.create命令: 將127.0.0.1修改爲阿里雲公網的ip地址 (123.456.200這是假ip)
加入redis密碼 -a 88888888
2.3.stop命令:加入redis密碼 -a 88888888
2.4.打開阿里雲端口
2.4.打開阿里雲端口

3.啓動集羣
#1.啓動集羣
sh /root/javaxiaobang/redis-5.0.5/utils/create-cluster/create-cluster start
#2.建立集羣間聯繫
sh /root/javaxiaobang/redis-5.0.5/utils/create-cluster/create-cluster create
#3.停止集羣
sh /root/javaxiaobang/redis-5.0.5/utils/create-cluster/create-cluster stop
#4.清除集羣
sh /root/javaxiaobang/redis-5.0.5/utils/create-cluster/create-cluster clean
4.連接redis
redis-cli -h 127.0.0.1 -p 7001 -c -a 密碼
-h ip地址
-p 端口號
-a 密碼
-c 集羣
