Redis羣集
部署安裝Redis
上傳redis程序包
[root@centos01 ~]# rz
[root@centos01 ~]# ls
anaconda-ks.cfg initial-setup-ks.cfg redis-3.2.9.tar.gz
解壓縮Redis程序包到/usr/src目錄
[root@centos01 ~]# tar zxvf redis-3.2.9.tar.gz -C /usr/src/
進入/usr/src/目錄，將軟件包程序剪切到redis目錄
[root@centos01 ~]# cd /usr/src/
[root@centos01 src]# ls
debug kernels redis-3.2.9
[root@centos01 src]# mv redis-3.2.9/ redis
[root@centos01 src]# ls
debug kernels redis
編輯安裝redis
[root@centos01 redis]# make && make install
初始化redis
[root@centos01 redis]# cd utils/
[root@centos01 utils]# ./install_server.sh
修改redis自主配置文件啓動羣集功能
[root@centos01 utils]# vi /etc/redis/6379.conf
62 bind 192.168.100.10
85 port 6379
129 daemonize yes
164 logfile /var/log/redis_6379.log
722 cluster-enabled yes
730 cluster-config-file nodes-6379.conf
736 cluster-node-timeout 15000
813 cluster-require-full-coverage no
啓動redis服務，並查看6379和16379端口是否正常啓動
[root@centos01 ~]# netstat -anptu | grep redis
tcp 0 0 192.168.100.10:6379 0.0.0.0:* LISTEN 4668/redis-server 1
tcp 0 0 192.168.100.10:16379 0.0.0.0:* LISTEN 4668/redis-server 1
掛載操作光盤，
[root@centos01 ~]# mount /dev/cdrom /mnt
mount: /dev/sr0 寫保護，將以只讀方式掛載
安裝羣集所需依賴程序
[root@centos01 ~]# yum -y install ruby rubygems
上傳準備好的gem軟件包
[root@centos01 ~]# rz
[root@centos01 ~]# ls
anaconda-ks.cfg redis-3.2.0.gem
initial-setup-ks.cfg redis-3.2.9.tar.gz
安裝gem工具
[root@centos01 ~]# gem install redis --version 3.2.0
將redis程序包遠程複製到192.168.100.20、30、40、50/60服務器的根目錄
[root@centos01 ~]# scp redis-3.2.9.tar.gz [email protected]:/root
[root@centos01 ~]# scp redis-3.2.9.tar.gz [email protected]:/root
[root@centos01 ~]# scp redis-3.2.9.tar.gz [email protected]:/root
[root@centos01 ~]# scp redis-3.2.9.tar.gz [email protected]:/root
[root@centos01 ~]# scp redis-3.2.9.tar.gz [email protected]:/root
部署第二臺redis服務器
掛載系統光盤
[root@centos02 ~]# mount /dev/cdrom /mnt
mount: /dev/sr0 寫保護，將以只讀方式掛載
安裝redis羣集依賴程序
[root@centos02 ~]# yum -y install ruby rubygems
解壓縮redis程序包，剪切到/usr/src/redis/src/redis-trib.rb/目錄
[root@centos02 ~]# tar zxvf redis-3.2.9.tar.gz -C /usr/src/
[root@centos02 src]# mv redis-3.2.9/ redis
[root@centos02 src]# ls
debug kernels redis
進入redis目錄，編輯安裝redis
[root@centos02 src]# cd redis/
[root@centos02 redis]# make && make install
初始化redis
[root@centos02 redis]# cd utils/
[root@centos02 utils]# ./install_server.sh
依次部署6臺redis服務器
在第一臺redis服務器上將redis主配置文件遠程複製到剩下5臺服務器上
[root@centos01 ~]# scp /etc/redis/6379.conf [email protected]:/etc/redis/
[root@centos01 ~]# scp /etc/redis/6379.conf [email protected]:/etc/redis/
[root@centos01 ~]# scp /etc/redis/6379.conf [email protected]:/etc/redis/
[root@centos01 ~]# scp /etc/redis/6379.conf [email protected]:/etc/redis/
[root@centos01 ~]# scp /etc/redis/6379.conf [email protected]:/etc/redis/
第二臺redis服務器修改主配置文件監聽的IP地址
[root@centos02 ~]# vim /etc/redis/6379.conf
bind 192.168.100.20
依次修改6臺
啓動redis服務，監聽redis服務是否正常啓動
[root@centos02 ~]# redis-server /etc/redis/6379.conf
[root@centos02 ~]# netstat -anptu | grep redis

使用腳本創建羣集
在第一臺redis服務器上使用腳本創建羣集
