Redis非关系型数据库群集

Redis非关系型数据库群集

部署及安装Redis

1） 上传redis程序包

10）安装gem工具
[root@centos01 ~]# ls
anaconda-ks.cfg initial-setup-ks.cfg redis-3.2.0.gem redis-3.2.9.tar.gz
[root@centos01 ~]# gem install redis –version 3.2.0

11）将redis程序包远程复制到100.20、30、40、50、60服务器的根目录
[root@centos01 ~]# scp redis-3.2.9.tar.gz root@192.168.100.20:/root

部署第二台redis服务器

1）挂载操作系统光盘，删除系统自动yum源
[root@centos02 ~]# mount /dev/cdrom /mnt/
mount: /dev/sr0 写保护，将以只读方式挂载
[root@centos02 ~]# rm -rf /etc/yum.repos.d/CentOS-*

2）安装redis群集所需依赖程序
[root@centos02 ~]# yum -y install ruby rubygems

3）解压缩redis程序包，剪切到/usr/src/redis/目录
[root@centos02 ~]# ls
anaconda-ks.cfg initial-setup-ks.cfg redis-3.2.9.tar.gz
[root@centos02 ~]# tar zxvf redis-3.2.9.tar.gz
[root@centos02 ~]# mv redis-3.2.9 /usr/src/redis/

5）初始化redis
[root@centos02 redis]# cd utils/
[root@centos02 utils]# ./install_server.sh
Welcome to the redis service installer
This script will help you easily set up a running redis server

Please select the redis port for this instance: [6379]
Selecting default: 6379
Please select the redis config file name [/etc/redis/6379.conf]
Selected default – /etc/redis/6379.conf
Please select the redis log file name [/var/log/redis_6379.log]
Selected default – /var/log/redis_6379.log
Please select the data directory for this instance [/var/lib/redis/6379]
Selected default – /var/lib/redis/6379
Please select the redis executable path [/usr/local/bin/redis-server]
Selected config:
Port : 6379
Config file : /etc/redis/6379.conf
Log file : /var/log/redis_6379.log
Data dir : /var/lib/redis/6379
Executable : /usr/local/bin/redis-server
Cli Executable : /usr/local/bin/redis-cli
Is this okhen press ENTER to go on or Ctrl-C to abort.
Copied /tmp/6379.conf => /etc/init.d/redis_6379

6）在第一台redis服务器上将redis主配置文件远程复制到剩下五台服务器上
[root@centos01 ~]# scp /etc/redis/6379.conf root@192.168.100.20:/etc/redis/

root@192.168.100.20’s password:
6379.conf 100% 46KB 37.4MB/s 00:00
[root@centos01 ~]# scp /etc/redis/6379.conf root@192.168.100.30:/etc/redis/

root@192.168.100.30’s password:
6379.conf 100% 46KB 27.9MB/s 00:00
[root@centos01 ~]# scp /etc/redis/6379.conf root@192.168.100.40:/etc/redis/

root@192.168.100.40’s password:
6379.conf 100% 46KB 13.5MB/s 00:00
[root@centos01 ~]# scp /etc/redis/6379.conf root@192.168.100.50:/etc/redis/

root@192.168.100.50’s password:
6379.conf 100% 46KB 35.4MB/s 00:00
[root@centos01 ~]# scp /etc/redis/6379.conf root@192.168.100.60:/etc/redis/

root@192.168.100.60’s password:
6379.conf 100% 46KB 44.7MB/s 00:00

7）第二台redis服务器修改主配置文件监听的IP地址
[root@centos02 ~]# vim /etc/redis/6379.conf
bind 192.168.100.20

8）启动redis服务，监听redis服务是否正常启动
[root@centos02 ~]# redis-server /etc/redis/6379.conf
[root@centos02 ~]# netstat -anptu | grep redis
tcp 0 0 192.168.100.20:6379 0.0.0.0:* LISTEN 6224/redis-server 1
tcp 0 0 192.168.100.20:16379 0.0.0.0:* LISTEN 6224/redis-server 1

剩下四台安装第二台的操作步骤做同样的配置即可，修改主配置文件监听的IP地址设置成服务器自己的IP地址即可

使用脚本创建群集

1）在第一台redis服务器上使用脚本创建群集
[root@centos01 ~]# /usr/src/redis/src/redis-trib.rb create –replicas 1 192.168.100.10:6379 192.168.100.20:6379 192.168.100.30:6379 192.168.100.40:6379 192.168.100.50:6379 192.168.100.60:6379
