試驗機(jī)操作系統(tǒng)：CentOS Linux release 7.5.1804 (Core)

下載Redis

下載版本：redis-4.0.1.tar.gz

[root@Centos7-1 ~]# wget http://download.redis.io/releases/redis-4.0.1.tar.gz

安裝gcc與psmisc

yum install gcc psmisc

解壓tar包

[root@Centos7-1 ~]# tar zxvf redis-4.0.1.tar.gz

[root@Centos7-1 ~]# mv redis-4.0.1 /usr/local/rediscd /soft

編譯安裝

[root@Centos7-1 ~]#cd /usr/local/redis

[root@Centos7-1 redis]#make MALLOC=libc

[root@Centos7-1 redis]#make & make install

說明：如果在make的時候不指定內(nèi)存管理方式，會報錯的：

zmalloc.h:50:31: 致命錯誤：jemalloc/jemalloc.h：沒有那個文件或目錄。

malloc是管理內(nèi)存碎片的。

使用systemctl管理服務(wù)

[root@Centos7-1 redis]# vim /lib/systemd/system/redis.service

[Unit] Description=Redis After=network.target [Service] ExecStart=/usr/local/bin/redis-server /usr/local/redis/redis.conf --daemonize no ExecStop=/usr/local/bin/redis-cli -h 127.0.0.1 -p 6379 shutdown [Install] WantedBy=multi-user.target

*   [Unit] 表示這是基礎(chǔ)信息

*   Description 是描述
*   After 是在那個服務(wù)后面啟動，一般是網(wǎng)絡(luò)服務(wù)啟動后啟動

*   [Service] 表示這里是服務(wù)信息

*   ExecStart 是啟動服務(wù)的命令
*   ExecStop 是停止服務(wù)的指令

*   [Install] 表示這是是安裝相關(guān)信息

*   WantedBy 是以哪種方式啟動：multi-user.target表明當(dāng)系統(tǒng)以多用戶方式（默認(rèn)的運(yùn)行級別）啟動時，這個服務(wù)需要被自動運(yùn)行。

刷新systemctl配置

[root@Centos7-1 redis]#systemctl daemon-reload

啟動reids

[root@Centos7-1 redis]#systemctl start redis; systemctl enable redis

[root@Centos7-1 redis]#systemctl status redis

===========================================

Redis集群安裝配置

redis集群最小是3主3從。

192.168.1.196      CentOS Linux release 7.5.1804 (Core)

192.168.1.127      CentOS Linux release 7.5.1804 (Core)

192.168.1.210      CentOS Linux release 7.5.1804 (Core)

192.168.1.46       CentOS Linux release 7.5.1804 (Core)

192.168.1.172      CentOS Linux release 7.5.1804 (Core)

192.168.1.173      CentOS Linux release 7.5.1804 (Core)

在一臺機(jī)器上裝好redis，然后拷貝到其他服務(wù)器上去。

安裝ruby

創(chuàng)建redis集群需要用Ruby運(yùn)行redis-trib.rb

[root@Centos7-1 redis]# yum install centos-release-scl-rh -y

[root@Centos7-1 redis]# yum install rh-ruby23 rh-ruby23-ruby-devel rubygems rpm-build -y

[root@Centos7-1 redis]# scl enable rh-ruby23 bash

1.移除現(xiàn)有的鏡像

[root@Centos7-1 redis]# gem sources --remove https://rubygems.org/

2.使用淘寶鏡像

[root@Centos7-1 redis]# gem sources -a https://ruby.taobao.org/

3.驗證當(dāng)前ruby版本

[root@Centos7-1 redis]# gem sources -l

[root@Centos7-1 redis]# gem install redis

修改redis.conf

打開redis.conf，把下面列出來的配置項全部注釋，完了拷貝下面7條配置到redis.conf文件末尾

port 6379

bind 192.168.1.196

daemonize yes

cluster-enabled yes

cluster-config-file nodes-6379.conf

cluster-node-timeout 15000

pidfile /var/run/redis_6379.pid

把每臺機(jī)器上的redis.conf中的bind修改成對于的IP

啟動redis

每臺都要啟動

[root@Centos7-1 redis]# systemctl restart redis

啟動集群

[root@Centos7-1 redis]# /usr/local/redis/src/redis-trib.rb create --replicas 1 192.168.1.196:6379 192.168.1.127:6379 192.168.1.210:6379 192.168.1.46:6379 192.168.1.172:6379 192.168.1.173:6379

連接redis集群

[root@localhost redis]# src/redis-cli -h 192.168.1.196 -c -p 6379

必須要加：-c參數(shù)

在192.168.1.196節(jié)點(diǎn)上寫一條數(shù)據(jù)：

[root@Centos7-1 redis]# redis-cli -h 192.168.1.196 -c -p 6379

192.168.1.196:6379> set key test

-> Redirected to slot [12539] located at 192.168.1.210:6379

OK

192.168.1.210:6379> get key

"test"

192.168.1.210:6379> set key2 test2

-> Redirected to slot [4998] located at 192.168.1.196:6379

OK

192.168.1.196:6379> get key2

"test2"

可以看到插入鍵值在196機(jī)器上，獲取鍵值的時候，自動跳到其他機(jī)器上

如果重啟服務(wù)器后，再次執(zhí)行redis-trib.rb會報錯如下錯誤：

[ERR] Node 192.168.1.80:6379 is not empty. Either the node already knows other nodes (check with CLUSTER NODES) or contains some key in database 0.

解決方法：

刪除dump.rdb和nodes-6379.conf這兩個文件，然后重啟redis服務(wù)，最后啟動集群。
