1.环境确认a.系统版本查看 [hadoop@p168 ~]$ cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core)? b.安装依赖 [hadoop@p168 ~]$?sudo yum?-y?install?tcl?ruby tree? ? 2.安装redis 3.0.6 [hadoop@p168 ~]#cd?/usr/local/ [hadoop@p168 ~]#wget?? [hadoop@p168 ~]#tar??xzf?redis-stable.tar.gz [hadoop@p168 ~]#cd?redis-stable [hadoop@p168 ~]#make [hadoop@p168 ~]#make?test [hadoop@p168 ~]#make?install ? 3.建立节点配置目录 ? [hadoop@p168 ~]#mkdir /etc/redis[hadoop@p168 ~]#mkdir /etc/redis/7000 ? 4.建立节点配置文件 a.配置7000节点,先复制redis-server与初始配置文件redis.conf,然后修改redis.conf,使其适合集群 [hadoop@p168 ~]#cp?/usr/local/redis-stable/src/redis-server ?/usr/local/redis-stable/redis.conf /etc/redis/7000 修改redis.conf,主要修改内容如下: [hadoop@p168 ~]#vim?/etc/redis/7000/redis.conf #/etc/redis/7000/redis.conf ? port?7000 daemonize????yes? pidfile??/var/run/redis_7000.pid cluster-enabled?yes cluster-config-file?nodes.conf logfile?"/var/log/redisd7000.log" dir?/etc/redis/7000/ cluster-node-timeout?5000 appendonly?yes ? b.复制其他节点配置文件 #生成7001配置,其他类似 cp?-r?7000 7001 sed?-i?"s/7000/7001/g"?7001/redis.conf cat??7001/redis.conf?|grep?7001 ? 5.配置节点开机启动 修改redisd7000的启动脚本,7001~7005类似 ? [hadoop@p168 ~]#cp?/usr/local/redis-stable/utils/redis_init_script?/etc/init.d/redisd7000 [hadoop@p168 ~]#vim??/etc/init.d/redisd7000 ? #!/bin/sh #chkconfig:????2345?90?10 #description:??Redis?is?a?persistent?key-value?database # #?Simple?Redis?init.d?script?conceived?to?work?on?Linux?systems #?as?it?does?use?of?the?/proc?filesystem. ? REDISPORT=7000 #EXEC=/usr/local/bin/redis-server EXEC=/etc/redis/${REDISPORT}/redis-server CLIEXEC=/usr/local/bin/redis-cli PIDFILE=/var/run/redis_${REDISPORT}.pid #CONF="/etc/redis/${REDISPORT}.conf" CONF="/etc/redis/${REDISPORT}/redis.conf" 主要修改内容包括如下三点: a.加入前三行即 #!/bin/sh #chkconfig:????2345?90?10 #description:??Redis?is?a?persistent?key-value?databaseb.修改端口,即 REDISPORT=7000c.指定EXEC与CONF即 EXEC=/etc/redis/${REDISPORT}/redis-server CONF="/etc/redis/${REDISPORT}/redis.conf"其他的不动,略 cat???/etc/init.d/redisd7001?|grep?7001 ? #设置为开机自启动服务器,其他服务类似 [hadoop@p168 ~]#chkconfig?redisd7000?on ? 确认配置文件,重启前应该是如下状态 [?~]#?ls?/etc/init.d/?|grep?redis redisd7000 redisd7001 redisd7002 redisd7003 redisd7004 redisd7005 注:以上文件是6个服务的自动启动脚本 [?~]#?tree?/etc/redis /etc/redis ├──?7000 │???├──?redis.conf │???└──?redis-server ├──?7001 │???├──?redis.conf │???└──?redis-server ├──?7002 │???├──?redis.conf │???└──?redis-server ├──?7003 │???├──?redis.conf │???└──?redis-server ├──?7004 │???├──?redis.conf │???└──?redis-server ├──?7005 │???├──?redis.conf │???└──?redis-server 注:以上目录是各服务器的redis-server可执行程序与其配置文件,若没有tree命令,先 yum install -y tree ? [hadoop@p168 ~]# reboot 重启以后服务应该就启动了,若有需要可以用如下命令来启动或停止服务了 service?redisd7000?start service?redisd7000?stop ? 6.安装redis接口 #rubygems.org被墙,换ruby.taobao.org gem?sources?--remove? gem?sources?-a? gem?install?redis ? 7.建立集群 [?redis-stable]#?/usr/local/redis-stable/src/redis-trib.rb??create?--replicas?1?192.168.1.161:7000?192.168.1.161:7001?192.168.1.161:7002?192.168.1.161:7003?192.168.1.161:7004?192.168.1.161:7005 >>>?Creating?cluster >>>?Performing?hash?slots?allocation?on?6?nodes...
