Linux下redis安装并设置开机自启
2.Redis 集群配置
具体是参考这篇文章由于在搭建过程中仍遇到很多问题所以在其基础上补充 Linux下redis集群搭建与部署
2.1 创建redis集群安装目录 cd /home/xh/hadoop/ mkdir myredis cd myredis mkdir 7000 7001 7002 7003 7004 7005 2.2 将redis单机部署目录下的redis.confi文件复制到每个目录下 cp /home/xh/hadoop/redis-3.2.5/redis.conf /home/xh/hadoop/myredis/7000 cp /home/xh/hadoop/redis-3.2.5/redis.conf /home/xh/hadoop/myredis/7001 cp /home/xh/hadoop/redis-3.2.5/redis.conf /home/xh/hadoop/myredis/7002 cp /home/xh/hadoop/redis-3.2.5/redis.conf /home/xh/hadoop/myredis/7003 cp /home/xh/hadoop/redis-3.2.5/redis.conf /home/xh/hadoop/myredis/7004 cp /home/xh/hadoop/redis-3.2.5/redis.conf /home/xh/hadoop/myredis/7005 2.3 修改每个文件夹下的redis.conf #例如 vim myredis/7000/redis.conf #修改如下 #端口号 port 7000 #后台启动 daemonize yes #开启集群 cluster-enabled yes #集群节点配置文件注意需要跟端口号一样 cluster-config-file nodes-7000.conf #数据文件存放位置(注意此处的路径需要自己创建好) dir /usr/local/redis/redis-cluster/7000/data/ #集群连接超时时间 cluster-node-timeout 5000 #进程pid的文件位置 注意需要跟端口号一样 pidfile /var/run/redis-7000.pid #开启aof appendonly yes #aof文件路径 appendfilename “appendonly-7000.aof” #rdb文件路径 dbfilename dump-7000.rdb 注意需要补充如下设置否则java连接报错 #保护模式设为no protected-mode no #绑定ip bind 192.168.240.128 2.4 修改完六个配置内容后开始启动 cd /usr/local/redis #这里闲一个个启动麻烦的话可以自己配置一个配置文件启动 bin/redis-server myredis/7000/redis.conf bin/redis-server myredis/7001/redis.conf bin/redis-server myredis/7002/redis.conf bin/redis-server myredis/7003/redis.conf bin/redis-server myredis/7004/redis.conf bin/redis-server myredis/7005/redis.conf 2.5 启动完后查看进程 [roothadoop myredis]# ps -ef|grep redis #显示有六个则是启动成功 root 63262 1 0 11:08 ? 00:00:00 redis-server 192.168.240.128:7000 [cluster] root 63264 1 0 11:08 ? 00:00:00 redis-server 192.168.240.128:7001 [cluster] root 63266 1 0 11:08 ? 00:00:00 redis-server 192.168.240.128:7002 [cluster] root 63270 1 0 11:08 ? 00:00:00 redis-server 192.168.240.128:7003 [cluster] root 63276 1 0 11:08 ? 00:00:00 redis-server 192.168.240.128:7004 [cluster] root 63278 1 0 11:08 ? 00:00:00 redis-server 192.168.240.128:7005 [cluster] root 63287 62960 0 11:08 pts/2 00:00:00 grep redis 2.6 建集群
到这里只是启动了六个单进程的redis开始创建集群先安装好ruby yum install ruby rubygems -y 使用gem要先镜像一下 #这里需要镜像一下 gem sources --add https://gems.ruby-china.com/ --remove https://rubygems.org/ #确保镜像成功 [roothadoop myredis]# gem sources -l *** CURRENT SOURCES *** https://gems.ruby-china.com/ 然后执行连接ruby-redis [roothadoop myredis]# gem install redis 上面步骤有可能报错查了资料发现是版本太低 解决办法是 先安装rvm再把ruby版本提升 ERROR: Error installing redis: redis requires Ruby version 2.3.0. ruby版本提升若没有报错不需要进行此步骤 #安装curl sudo yum install curl #安装rvm curl -L get.rvm.io | bash -s stable (如出现错误参考: http://blog.csdn.net/qq_30242987/article/details/99727838) source /usr/local/rvm/scripts/rvm #查看rvm库中已知的ruby版本 rvm list known #安装一个ruby版本 rvm install 2.4.0 #使用一个ruby版本 rvm use 2.4.0 #卸载一个已知版本 rvm remove 2.3.0 #查看版本 ruby --version #再安装redis就可以了 gem install redis 创建集群 #进入src下面 cd /home/xh/hadoop/redis-3.2.5/src # 创建集群

[OK] All nodes agree about slots configuration.Check for open slots...Check slots coverage...
[OK] All 16384 slots covered.到这里集群就安装好了测试一下

frank在启动时会发现一个个启动太麻烦这里配置一下启动关闭文件
#进入安装redis的路径
cd /home/xh/hadoop/myredis#编写关闭文件
vi stop-all.sh#加入下面内容编辑完之后按esc键输入 :wq 退出保存
#这里得找到自己配置启动得地方我得是在bin下面
