一、离线安装方式
1.下载离线软件包
下载地址：[https://github.com/microsoftarchive/redis]
redis-6.2.5-1.el7.remi.x86_64.rpm
2.安装redis
rpm -ivh redis-6.2.5-1.el7.remi.x86_64.rpm
3.修改配置文件
sed -i '/ *#/d; /^$/d' #把所有注释项全部为空
vim /etc/redis/redis.conf
...
daemonize yes
port 7000
bind 10.0.0.105
masterauth "your_password"
requirepass "your_password"
4.启动redis
/usr/bin/redis-server /etc/redis/redis.conf
5.停止redis
/usr/bin/redis-cli -h your_url -p 7000 -a your_password shutdown
二、源码编译安装redis
1.先去Redis官网下载tar包 这儿是下载6.2.13版本
[https://download.redis.io/releases/redis-7.2.4.tar.gz] [https://redis.io/download] #官网地址
2.下载完成后拉倒自己服务器里面解压
安装依赖包： yum -y install gcc gcc-c++ automake autoconf libtool make libc tcl
[root@minlo01 ~]# tar xf redis-6.2.13.tar.gz -C /usr/
3.解压完成后进入redis-6.2.13目录 然后编译安装
[root@minlo01 ~]# cd /usr/redis-6.2.13
[root@minlo01 redis-6.2.13]# make && make install
4.配置文件中设置启动服务后台运行,找到daemon 改为yes
[root@minlo01 ~]# vim /usr/redis-6.2.13/redis.conf
...
daemonize yes
...
5.配置文件中设置密码 进入配置文件redis.conf中找到# requirepass foobared
[root@minlo01 ~]# vim /usr/redis-6.2.13/redis.conf
...
masterauth 123
requirepass 123
...
6.然后启动Redis服务 server是要注意需要指定配置文件，不然不读
[root@minlo01 redis-6.2.13]# redis-server redis.conf
7.然后登录时需要 -a 指定你修改的密码
[root@minlo01 redis-6.2.13]# redis-cli -a 123
8.后面一下操作测试下redis ，一些redis基本命令，出现Warning不用管这是提示密码在命令行显示不安全
[root@minlo01 redis-6.2.13]# redis-cli -a 123
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
127.0.0.1:6379> selcet 1 # select 数据库编号
ok
127.0.0.1:6379> set test 123 #设置键值对
ok
127.0.0.1:6379> get test #取出键值对
"123"
127.0.0.1:6379> keys test #查看一个键是否存在
1) "test"
127.0.0.1:6379> del test1 #删除键值对
(integer)
127.0.0.1:6379> flushall #清空所有数据库中的数据
三、部署redis集群
1.准备工作目录和软件包
1.创建工作目录
mkdir /data/{redis-cluster-7000,logs} -p
2.下载软件包
wget https://download.redis.io/releases/redis-7.2.4.tar.gz
3.解压软件包
tar xf redis-7.2.4.tar.gz -C /data/
4.安装redis
cd /data/redis-7.2.4
make && make install
2.创建目录
cd /data/redis-7.2.4
mkdir {bin,conf,logs}
mv src/redis-benchmark src/redis-check-aof src/redis-cli src/redis-server /data/redis-7.2.4/bin/
mv redis.conf conf/
3.修改配置文件
sed -i '/ *#/d; /^$/d' redis.conf #把所有注释项全部为空
vim redis.conf
...
daemonize yes
port 7000
bind 10.0.0.141
dir "/data/redis-7.2.4/"
cluster-enabled yes
cluster-config-file "/data/redis-7.2.4/nodes-7000.conf"
cluster-node-timeout 15000
appendonly no
# save ""
dbfilename "dump-7000.rdb"
rdbcompression yes
rdbchecksum yes
tcp-backlog 511
tcp-keepalive 60
repl-disable-tcp-nodelay yes
timeout 0
loglevel notice
logfile "/data/redis-7.2.4/logs/redis.log"
requirepass "myredispassword"
masterauth "myredispassword"
maxclients 100000
# Generated by CONFIG REWRITE
pidfile "/var/run/redis.pid"
maxmemory-policy allkeys-lru
maxmemory 1gb
# user default on #074e7123c76bae5dedbc082ebe80bacb4de38ca0bcc540190428285675c1c269 ~* &* +@all
4.启动redis
1.启动redis
redis-server /data/redis-7.2.4/conf/redis.conf
2.验证redis
ps -ef|grep redis
root 7175 1 0 14:38 ? 00:00:00 redis-server 10.0.0.141:7000 [cluster]
root 7183 1465 0 14:38 pts/0 00:00:00 grep --color=auto redis
验证端口：
ss -ntl|grep 7000
LISTEN 0 128 10.0.0.141:7000 *:*
LISTEN 0 128 10.0.0.141:17000
3.停止redis
(1)
redis-cli -h 10.0.0.141 -p 7000 -a myredispassword
shutdown
exit
(2)
redis-cli shutdown
(3)
ps -ef|grep -v grep | grep redis| awk '{print $2}'| xargs kill -9
5.验证登录
1.登录客户端
redis-cli -h 10.0.0.115 -p 7000 -a myredispassword
redis-cli -h 10.0.0.116 -p 7000 -a myredispassword
...
2.
redis-cli -h 10.0.0.115 -p 7000 -c
10.0.0.115:7000> auth myredispassword
OK
6.创建集群
1.直接在命令行执行：
redis-cli --cluster create \
10.0.0.141:7000 \
10.0.0.142:7000 \
10.0.0.143:7000 \
10.0.0.114:7000 \
10.0.0.115:7000 \
10.0.0.116:7000 \
--cluster-replicas 1 \
-a 'myredispassword'
#日志输出即创建完成
[OK] All nodes agree about slots configuration.
>>> Check for open slots...
>>> Check slots coverage...
[OK] All 16384 slots covered.
2. 验证集群：
[root@mysql-114 conf]# redis-cli -h 10.0.0.115 -p 7000 -c
10.0.0.115:7000> auth myredispassword
OK
10.0.0.115:7000> cluster nodes
