redis集群搭建

一、说明： 1、redis节点 3主 3从 192.168.1.55:6300 192.168.1.55:6301 wh-52 192.168.1.59:6300 192.168.1.59:6301 wh-53 192.168.1.87:6300 192.168.1.87:6301 wh-54 2、redis版本 ：最新稳定版3.0.6 3、安装配置 安装目录：/usr/local/src/redis-3.0.6/src/ 配置文件：/et/redis_630{0,1}.conf 二、搭建 1、安装redis-3.0.6 [root@wh-52 ~]#cd /usr/local/src [root@wh-52 src]# wget http://download.redis.io/releases/redis-3.0.6.tar.gz [root@wh-52 src]# tar zxvf redis-3.0.6.tar.gz [root@wh-52 src]# yum install gcc openssl-devel pcre-devel zlib-devel ruby rubygems [root@wh-52 src]# cd redis-3.0.6 [root@wh-52redis-3.0.6]# make [root@wh-52redis-3.0.6]# make test 2、集群创建准备 [root@wh-52 ~]# cd /usr/local/src/redis-3.0.6/src/ [root@wh-52 src]# cp redis-trib.rb redis-server redis-cli /bin/ 安装ruby及ruby的redis模块 [root@wh-52 src]# yum -y install ruby rubygems [root@wh-52 src]# gem install redis --version 3.0.6 （等1分钟） Successfully installed redis-3.0.6 1 gem installed Installing ri documentation for redis-3.0.6... Installing RDoc documentation for redis-3.0.6... 创建目录（配置文件涉及到的目录） [root@wh-52 src]# cd /home/ [root@wh-52 home]# mkdir redis_6300 redis_6301 创建配置文件（注意端口修改） [root@wh-52~]# cd /etc [root@wh-52 etc]# touch redis_6300.conf redis_6301.conf [root@wh-52 etc]# vi redis_6300.conf [root@wh-52 etc]# vi redis_6301.conf 启动端口服务 [root@wh-52 etc]# /usr/local/src/redis-3.0.6/src/redis-server /etc/redis_6300.conf [root@wh-52 etc]# /usr/local/src/redis-3.0.6/src/redis-server /etc/redis_6301.conf 同样方法，对剩余2台主机做同样的操作。 3、创建集群 #选举规则 节点角色由启动顺序决定,先master之后是slave，本文中6300是master，6301是slave 初始化集群 [root@wh-53 etc]# /usr/local/src/redis-3.0.6/src/redis-trib.rb create --replicas 1 192.168.1.55:6300 192.168.1.59:6300 192.168.1.87:6300 192.168.1.55:6301 192.168.1.59:6301 192.168.1.87:6301 查看集群状态、列出节点详细信息 [root@wh-53 etc]# /usr/local/src/redis-3.0.6/src/redis-cli -c -p 6300 127.0.0.1:6300> CLUSTER info 127.0.0.1:6300> CLUSTER nodes 5、集群测试 手动关闭一个redis-server端口进程（以192.168.1.87为例）。可以看到（87:6300）down，（59:6301）mater [root@wh-54 etc]# netstat -lnp |grep redis tcp 0 0 0.0.0.0:16300 0.0.0.0:* LISTEN 3026/redis-server * tcp 0 0 0.0.0.0:16301 0.0.0.0:* LISTEN 3030/redis-server * tcp 0 0 0.0.0.0:6300 0.0.0.0:* LISTEN 3026/redis-server * tcp 0 0 0.0.0.0:6301 0.0.0.0:* LISTEN 3030/redis-server * tcp 0 0 :::16300 :::* LISTEN 3026/redis-server * tcp 0 0 :::16301 :::* LISTEN 3030/redis-server * tcp 0 0 :::6300 :::* LISTEN 3026/redis-server * tcp 0 0 :::6301 :::* LISTEN 3030/redis-server * [root@wh-54 etc]# kill -9 3026 [root@wh-54 etc]# /usr/local/src/redis-3.0.6/src/redis-cli -c -p 6301 127.0.0.1:6301> CLUSTER nodes 60ec356fa9e3a60d50b6b5a6c66520a8f3b63e21 192.168.1.87:6300 master,fail - 1454326034837 1454326028321 3 disconnected 1368481dd24815935e911c08b5a6c38c4cdc994c 192.168.1.59:6301 master - 0 1454326120686 7 connected 0-5460 acc3382b04838c7398aa3584514c15b64637c96b 192.168.1.87:6301 myself,slave d7aeefc22768484264a9028bc2c123c73e697895 0 0 6 connected bfdfaf93e9ce73e485cd5f464dd0278b06bc3f2b 192.168.1.55:6300 master - 0 1454326119182 1 connected 10923-16383 d7aeefc22768484264a9028bc2c123c73e697895 192.168.1.59:6300 master - 0 1454326122695 2 connected 5461-10922 dfbaf848ce5731249712c2902344127b74b0c9f1 192.168.1.55:6301 slave bfdfaf93e9ce73e485cd5f464dd0278b06bc3f2b 0 1454326121691 4 connected 恢复该端口进程，可以看到（87:6300）变成slave角色，（59:6301）还是mater [root@wh-54 etc]# /usr/local/src/redis-3.0.6/src/redis-server /etc/redis_6300.conf [root@wh-54 etc]# /usr/local/src/redis-3.0.6/src/redis-cli -c -p 6301 127.0.0.1:6301> CLUSTER NODES 60ec356fa9e3a60d50b6b5a6c66520a8f3b63e21 192.168.1.87:6300 slave 1368481dd24815935e911c08b5a6c38c4cdc994c 0 1454326652647 7 connected 1368481dd24815935e911c08b5a6c38c4cdc994c 192.168.1.59:6301 master - 0 1454326653648 7 connected 0-5460 acc3382b04838c7398aa3584514c15b64637c96b 192.168.1.87:6301 myself,slave d7aeefc22768484264a9028bc2c123c73e697895 0 0 6 connected bfdfaf93e9ce73e485cd5f464dd0278b06bc3f2b 192.168.1.55:6300 master - 0 1454326654649 1 connected 10923-16383 d7aeefc22768484264a9028bc2c123c73e697895 192.168.1.59:6300 master - 0 1454326650640 2 connected 5461-10922 dfbaf848ce5731249712c2902344127b74b0c9f1 192.168.1.55:6301 slave bfdfaf93e9ce73e485cd5f464dd0278b06bc3f2b 0 1454326651644 4 connected 6、经过检验，实验成功完成。后期继续集群理论的学习。 不要让懒惰占据你的大脑，不让要妥协拖跨你的人生。青春就是一张票，能不能赶上时代的快车，你的步伐掌握在你的脚下，good luck
