在Windows系統(tǒng)下搭建Redis集群
2021-10-27 14:44:08

準(zhǔn)備工作

?需要4個(gè)部件：Redis、Ruby語言運(yùn)行環(huán)境、Redis的Ruby驅(qū)動(dòng)redis-xxxx.gem、創(chuàng)建Redis集群的工具redis-trib.rb。使用redis-trib.rb工具來創(chuàng)建Redis集群，由于該文件是用ruby語言寫的，所以需要安裝Ruby開發(fā)環(huán)境，以及驅(qū)動(dòng)redis-xxxx.gem。

在Windows系統(tǒng)下搭建Redis集群_5e

?

1）下載Redis安裝文件：https://github.com/MSOpenTech/redis/releases/，Redis提供msi和zip格式的下載文件，這里下載zip格式Redis-x64-3.2.100版本。

2）下載Ruby安裝文件：http://dl.bintray.com/oneclick/rubyinstaller/rubyinstaller-2.2.4-x64.exe

3）下載Ruby環(huán)境下Redis的驅(qū)動(dòng)：https://rubygems.org/gems/redis/versions/3.2.2，考慮到兼容性，這里下載的是3.2.2版本

注意：下載在頁面右下角相關(guān)連接一項(xiàng)中

在Windows系統(tǒng)下搭建Redis集群_d3_02

4）下載Redis官方提供的創(chuàng)建Redis集群的ruby腳本文件redis-trib.rb，路徑如下：https://raw.githubusercontent.com/MSOpenTech/redis/3.0/src/redis-trib.rb

安裝Redis

將下載到的Redis-x64-3.2.100.zip解壓即可，為了方便使用，建議放在盤符根目錄下，如：D:Redis-ClusterRedis-x64-3.2.100。?

安裝Redis，并運(yùn)行3個(gè)實(shí)例(Redis集群需要至少3個(gè)以上節(jié)點(diǎn)，低于3個(gè)無法創(chuàng)建)；

通過配置文件來啟動(dòng)6個(gè)不同的Redis實(shí)例，由于Redis默認(rèn)端口為6379，所以這里使用了6380、6381、6382、6383、6384、6385來運(yùn)行6個(gè)Redis實(shí)例。

注意：

　　1）為了避免不必要的錯(cuò)誤，配置文件盡量保存為utf8格式，并且不要包含注釋；

　　2）配置文件中以下兩種保存日志的方式(保存在文件中、保存到System Log中)請根據(jù)需求選擇其中一種即可：

loglevel notice                                                     #日志的記錄級(jí)別，notice是適合生產(chǎn)環(huán)境的
logfile "D:/Redis-Cluster/Redis-x64-3.2.100/Logs/redis6380_log.txt" #指定log的保持路徑,默認(rèn)是創(chuàng)建在Redis安裝目錄下，如果有子目錄需要手動(dòng)創(chuàng)建，如此處的Logs目錄
syslog-enabled yes                                                  #是否使用系統(tǒng)日志 　　
syslog-ident redis6380                                              #在系統(tǒng)日志的標(biāo)識(shí)名

這里使用了保存在文件中的方式，所以先在Redis目錄D:Redis-ClusterRedis-x64-3.2.100下新建Logs文件夾。

在Redis安裝根目錄下，創(chuàng)建編碼格式為utf-8的配置文件：redis.6380.conf、redis.6381.conf、redis.6382.conf、redis.6383.conf、redis.6384.conf、redis.6385.conf。

配置解釋如下：

 1 port 6380                                 #端口號(hào)
 2 loglevel notice                           #日志的記錄級(jí)別，notice是適合生產(chǎn)環(huán)境的
 3 logfile "Logs/redis6380_log.txt"          #指定log的保持路徑,默認(rèn)是創(chuàng)建在Redis安裝目錄下，如果有子目錄需要手動(dòng)創(chuàng)建，如此處的Logs目錄

 6 appendonly yes                            #數(shù)據(jù)的保存為aof格式
 7 appendfilename "appendonly.6380.aof"      #數(shù)據(jù)保存文件
 8 cluster-enabled yes                       #是否開啟集群
 9 cluster-config-file nodes.6380.conf
10 cluster-node-timeout 15000
11 cluster-slave-validity-factor 10
12 cluster-migration-barrier 1
13 cluster-require-full-coverage yes

將上述配置文件保存到Redis目錄下，并使用這些配置文件安裝6個(gè)redis服務(wù)，命令如下：

D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-install D:/Redis-Cluster/Redis-x64-3.2.100/redis.6380.conf --service-name redis6380
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-install D:/Redis-Cluster/Redis-x64-3.2.100/redis.6381.conf --service-name redis6381
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-install D:/Redis-Cluster/Redis-x64-3.2.100/redis.6382.conf --service-name redis6382
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-install D:/Redis-Cluster/Redis-x64-3.2.100/redis.6383.conf --service-name redis6383
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-install D:/Redis-Cluster/Redis-x64-3.2.100/redis.6384.conf --service-name redis6384
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-install D:/Redis-Cluster/Redis-x64-3.2.100/redis.6385.conf --service-name redis6385

注意：

1）redis.6380.conf等配置文件最好使用完整路徑，避免重啟Redis集群出現(xiàn)問題

2）卸載命令為：

D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-uninstall D:/Redis-Cluster/Redis-x64-3.2.100/redis.6380.conf --service-name redis6380
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-uninstall D:/Redis-Cluster/Redis-x64-3.2.100/redis.6381.conf --service-name redis6381
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-uninstall D:/Redis-Cluster/Redis-x64-3.2.100/redis.6382.conf --service-name redis6382
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-uninstall D:/Redis-Cluster/Redis-x64-3.2.100/redis.6383.conf --service-name redis6383
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-uninstall D:/Redis-Cluster/Redis-x64-3.2.100/redis.6384.conf --service-name redis6384
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-uninstall D:/Redis-Cluster/Redis-x64-3.2.100/redis.6385.conf --service-name redis6385

啟動(dòng)這6個(gè)服務(wù)，命令如下：

D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6380
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6381
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6382
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6383
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6384
D:/Redis-Cluster/Redis-x64-3.2.100/redis-server.exe --service-start --service-name redis6385

執(zhí)行結(jié)果：

在Windows系統(tǒng)下搭建Redis集群_Redis_15

安裝ruby

1）Ruby環(huán)境安裝。

雙擊下載的“rubyinstaller-2.2.4-x64.exe”安裝即可，同樣，為了操作方便，也是建議安裝在盤符根目錄下，如： C:Ruby22-x64 ，安裝時(shí)這里選中后兩個(gè)選項(xiàng)，

在Windows系統(tǒng)下搭建Redis集群_d3_16

意思是將ruby添加到系統(tǒng)的環(huán)境變量中，在cmd命令中能直接使用ruby的命令

2）安裝Ruby環(huán)境下Redis的驅(qū)動(dòng)

將下載的"Ruby環(huán)境下Redis的驅(qū)動(dòng)文件(redis-3.2.2.gem)"拷貝到Ruby安裝根目錄（C:Ruby22-x64）下。

然后執(zhí)行安裝命令如下：

gem install --local path_to_gem/filename.gem

在Windows系統(tǒng)下搭建Redis集群_redis_17

創(chuàng)建Redis集群

將下載的“創(chuàng)建Redis集群的ruby腳本文件redis-trib.rb”文件拷貝到Redis安裝根目錄(D:Redis-ClusterRedis-x64-3.2.100)下。

1）使用redis-trib.rb來創(chuàng)建Redis集群

MD下切換到Redis目錄(D:Redis-ClusterRedis-x64-3.2.100)

2）?redis-trib.rb工具的使用

1、create：創(chuàng)建集群
2、check：檢查集群
3、info：查看集群信息
4、fix：修復(fù)集群
5、reshard：在線遷移slot
6、rebalance：平衡集群節(jié)點(diǎn)slot數(shù)量
7、add-node：將新節(jié)點(diǎn)加入集群
8、del-node：從集群中刪除節(jié)點(diǎn)

2）檢驗(yàn)是否真的創(chuàng)建成功

輸入以下命令：

基礎(chǔ)才是編程人員應(yīng)該深入研究的問題，比如:
1）List/Set/Map內(nèi)部組成原理|區(qū)別
2）mysql索引存儲(chǔ)結(jié)構(gòu)&如何調(diào)優(yōu)/b-tree特點(diǎn)、計(jì)算復(fù)雜度及影響復(fù)雜度的因素。。。
3）JVM運(yùn)行組成與原理及調(diào)優(yōu)
4）Java類加載器運(yùn)行原理
5）Java中GC過程原理|使用的回收算法原理
6）Redis中hash一致性實(shí)現(xiàn)及與hash其他區(qū)別
7）Java多線程、線程池開發(fā)、管理Lock與Synchroined區(qū)別
8）Spring IOC/AOP 原理；加載過程的。。。
