单机集群部署(redis8.2.2)
环境:
OS:Centos 7
redis:8.2.2
角色 机器ip
主 192.168.1.108 7001
从 192.168.1.108 7002
主 192.168.1.108 7003
从 192.168.1.108 7004
主 192.168.1.108 7005
从 192.168.1.108 7006
1.下载安装介质
我这里下载的是redis-8.2.2.tar.gz
下载地址:
http://download.redis.io/releases/
2.解压介质并安装
[root@localhost soft]# tar -xvf redis-8.2.2.tar.gz
[root@localhost soft]# cd redis-8.2.2/src
[root@node2 src]# make
[root@node2 src]# make test
没有问题的话，会输入如下信息
\o/ All tests passed without errors!
Cleanup: may take some time... OK
make[1]: Leaving directory `/soft/redis-8.2.2/src'
安装到指定的目录,默认是安装在/usr/bin目录,我们这里统一安装到/usr/local/services/redis目录,该目录不用提前创建
[root@node2 src]# make PREFIX=/usr/local/services/redis install
INSTALL redis-sentinel
INSTALL redis-check-rdb
Hint: It's a good idea to run 'make test' ;)
INSTALL redis-server
INSTALL redis-benchmark
INSTALL redis-cli
3.创建目录并修改相应权限
[root@localhost src]# mkdir -p /home/middle/redis/conf
[root@localhost src]# mkdir -p /home/middle/redis/data
[root@localhost src]# mkdir -p /home/middle/redis/logs
[root@localhost src]# mkdir -p /home/middle/redis/run
创建数据目录
[root@localhost src]#mkdir -p /home/middle/redis/data/redis_7001
[root@localhost src]#mkdir -p /home/middle/redis/data/redis_7002
[root@localhost src]#mkdir -p /home/middle/redis/data/redis_7003
[root@localhost src]#mkdir -p /home/middle/redis/data/redis_7004
[root@localhost src]#mkdir -p /home/middle/redis/data/redis_7005
[root@localhost src]#mkdir -p /home/middle/redis/data/redis_7006
4.创建配置文件
vi /home/middle/redis/conf/7001.conf
内如如下:

拷贝 7001.conf 生成 7002.conf 配置文件
cd /home/middle/redis/conf
cp 7001.conf 7002.conf
cp 7001.conf 7003.conf
cp 7001.conf 7004.conf
cp 7001.conf 7005.conf
cp 7001.conf 7006.conf
替换修改配置文件的内容
sed -i 's/7001/7002/g' /home/middle/redis/conf/7002.conf
sed -i 's/7001/7003/g' /home/middle/redis/conf/7003.conf
sed -i 's/7001/7004/g' /home/middle/redis/conf/7004.conf
sed -i 's/7001/7005/g' /home/middle/redis/conf/7005.conf
sed -i 's/7001/7006/g' /home/middle/redis/conf/7006.conf

----------------------------配置集群-------------------------------------
1.创建集群
/usr/local/services/redis/bin/redis-cli --cluster create 192.168.1.108:7001 192.168.1.108:7002 192.168.1.108:7003 192.168.1.108:7004 192.168.1.108:7005 192.168.1.108:7006 --cluster-replicas 1
报错:
[root@master conf]# /usr/local/services/redis/bin/redis-cli --cluster create 192.168.1.108:7001 192.168.1.108:7002 192.168.1.108:7003 192.168.1.108:7004 192.168.1.108:7005 192.168.1.108:7006 --cluster-replicas 1
[ERR] Node 192.168.1.108:7001 DENIED Redis is running in protected mode because protected mode is enabled and no password is set for the default user. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Set up an authentication password for the default user. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.

解决办法：
停掉各节点进程,然后修改配置文件启用密码,再次启动,创建集群的时候带上密码
/usr/local/services/redis/bin/redis-cli --cluster create 192.168.1.108:7001 192.168.1.108:7002 192.168.1.108:7003 192.168.1.108:7004 192.168.1.108:7005 192.168.1.108:7006 --cluster-replicas 1 -a hxl2018
