redis集群安装多端口多实例部署

目标（本文达成的结果，配对关系可能会变）：

先在131上进行操作

1.下载redis

http://download.redis.io/releases/redis-5.0.2.tar.gz

2.解压

[testapp@k8s-node2 ~]$ mkdir redis

[testapp@k8s-node2 ~]$ cd redis

上传文件

[testapp@k8s-node2 ~/redis]$ tar -zxvf redis-5.0.2.tar.gz

3.修改/usr/local/bin/权限

su - root

chmod 777 /usr/local/bin/

su - testapap

建立文件夹

[testapp@k8s-node2 ~/redis]$ mkdir redis_cluster

[testapp@k8s-node2 ~/redis]$ mkdir logs

[testapp@k8s-node2 ~/redis]$ touch logs/redis_run.logs

[testapp@k8s-node2 ~/redis]$ cp /redis-5.0./redis.conf .
[testapp@k8s-node1 ~/redis]$ ll
总用量
drwxrwxr-x  testapp testapp       8月   : logs
drwxrwxr-x  testapp testapp      11月   redis-5.0.
-rw-rw-r--  testapp testapp  8月   : redis-5.0..tar.gz
drwxrwxr-x  testapp testapp      8月   : redis_cluster

[testapp@k8s-node1 ~/redis]$ pwd
/home/ap/testapp/redis

4.修改配置文件

port 6380 //端口（从节点使用6381端口）

#bind 127.0.0.1 //需要注释掉该配置

daemonize yes //redis后台运行

logfile “/home/ap/testapp/redis/logs/redis_run.log”//配置redis日志路径

pidfile /home/ap/testapp/redis/redis_cluster/redis_6380.pid //redis的进程文件

appendonly yes //aof日志开启 有需要就开启，它会每次写操作都记录一条日志　

dir /home/ap/testapp/redis/redis_cluster/ //数据库备份的文件放置的路径

Protected-mode no //是否开启保护模式

cluster-enabled yes //开启集群 把注释#去掉

cluster-config-file /home/ap/testappl/redis/redis_cluster/nodes_6380.conf //集群的配置

cluster-node-timeout 15000 //请求超时 默认15秒，可自行设置

5.安装

cd redis-5.0.2

make && make install

6.启动

/home/ap/testapp/redis/redis-5.0.2/src/redis-server /home/ap/testapp/redis/redis_cluster/redis.conf

ps -ef | grep redis

7.关闭防墙

systemctl status firewalld //查看防火墙状态
systemctl is-enabled firewalld //查看开机是否启动防火墙服务
systemctl stop firewalld //关闭防火墙
systemctl disable firewalld //禁用防火墙（系统启动时不启动防火墙服务）

8.组成集群

关闭6380

/home/ap/testapp/software/redis/redis-5.0.2/src/redis-cli -c -p 6380 shutdown

配置集群conf

cp redis.conf redis6380.conf

cp redis.conf redis6381.conf ##并更改内容中6380 为6381

cp redis.conf redis6382.conf ##并更改内容中6380 为6382

rm redis.conf

依次启动6380 6381 6382

/home/ap/testapp/redis/redis-5.0.2/src/redis-server /home/ap/testapp/redis/redis_cluster/redis6380.conf

/home/ap/testapp/redis/redis-5.0.2/src/redis-server /home/ap/testapp/redis/redis_cluster/redis6381.conf

/home/ap/testapp/redis/redis-5.0.2/src/redis-server /home/ap/testapp/redis/redis_cluster/redis6382.conf

再在192.168.111.132重复1--8

组成集群

[testapp@k8s-node1 ~/redis/redis_cluster]$ cat flushCluster.sh
##判断参数
if [ $# -eq  ]
then
    echo -e "usage: sh $0 ip \nexit!!"
    exit

##关闭服务
/home/ap/testapp/redis/redis-5.0./src/redis-cli -c -p ${port} shutdown

9.为集群中的每一个节点设置密码

修改每个redis638*.conf

masterauth <master-password>  改为  masterauth test@123

requirepass foobared   改为 requirepass test@123

一向比较懒的我

[testapp@k8s-node2 ~/redis/redis_cluster]$  sed 's/# masterauth <master-password>/masterauth test@123/g' redis638*.conf|grep test@123 ##尝试修改，并显示结果
masterauth test@
masterauth test@
masterauth test@
[testapp@k8s-node2 ~/software/redis/redis_cluster]$  sed -i 's/# masterauth <master-password>/masterauth test@123/g' redis638*.conf  ##加-i表示真正修改源文件

同理

[testapp@k8s-node2 ~/redis/redis_cluster]$  sed  's/# requirepass foobared/requirepass test@123/g' redis638*.conf|grep test@
masterauth test@
requirepass test@
masterauth test@
requirepass test@
masterauth test@
requirepass test@
[testapp@k8s-node2 ~/redis/redis_cluster]$  sed  -i 's/# requirepass foobared/requirepass test@123/g' redis638*.conf

验证

[testapp@k8s-node2 ~/software/redis/redis_cluster]$ grep test@ redis638*.conf
redis6380.conf:masterauth test@
redis6380.conf:requirepass test@
redis6381.conf:masterauth test@
redis6381.conf:requirepass test@
redis6382.conf:masterauth test@
redis6382.conf:requirepass test@

然后重启

sh stopAll.sh

sh startAll.sh

[testapp@k8s-node2 ~/redis/redis_cluster]$ sh stopAll.sh
[testapp@k8s-node2 ~/redis/redis_cluster]$ sh startAll.sh
[testapp@k8s-node2 ~/redis/redis_cluster]$ ps -ef|grep redis

验证，不输入密码，报NOAUTH Authentication required
