SUSE Linux 11下Redis环境搭建

共计 7128 个字符，预计需要花费 18 分钟才能阅读完成。

因为工作环境中有 Redis，所以对 Redis 进行了学习，当然首先就是从搭建环境开始，下面是我对于搭建 Redis 环境的记录。

系统是 SUSE 11 sp2,

软件环境如下所示：

linux-svnfile:/home/apps/redis # ls

redis-3.0.0.gem    ruby-1.9.2-p290.tar.gz  zlib-1.2.7.tar.gz

redis-3.0.0.tar.gz  rubygems-2.4.6.tgz

redis.conf          zlib-1.2.6.tar.gz

安装基础环境：

linux-svnfile:/home/apps/redis # tar -zxf zlib-1.2.6.tar.gz -C /usr/local/src

linux-svnfile:/usr/local/src/zlib-1.2.6 # ./configure –prefix=/usr/local/zlib

linux-svnfile:/usr/local/src/zlib-1.2.6 # make && make install

linux-svnfile:/home/apps/redis # tar -zxf ruby-1.9.2-p290.tar.gz -C /usr/local/src

linux-svnfile:/usr/local/src/ruby-1.9.2-p290 # ./configure –prefix=/usr/local/ruby

linux-svnfile:/usr/local/src/ruby-1.9.2-p290 # make && make install

linux-svnfile:/usr/local/ruby # ln -s /usr/local/ruby/bin/ruby /usr/local/bin

linux-svnfile:/home/apps/redis # tar xf rubygems-2.4.6.tgz -C /usr/local/src

linux-svnfile:/usr/local/src # mv rubygems-2.4.6 ../gem

linux-svnfile:/usr/local/gem # ruby setup.rb

linux-svnfile:/usr/local/gem # cp bin/gem /usr/local/bin/

linux-svnfile:/home/apps/redis # gem install -l redis-3.0.0.gem

Successfully installed redis-3.0.0

Installing ri documentation for redis-3.0.0

Done installing documentation for redis after 0 seconds

1 gem installed

linux-svnfile:/home/apps/redis # tar -zxf redis-3.0.0.tar.gz -C /usr/local/src

linux-svnfile:/usr/local/src # mv redis-3.0.0 ../redis

linux-svnfile:/usr/local/redis # make

至此基础环境搭建完成

下面进行集群的搭建

linux-svnfile:/usr/local/redis # cp src/redis-server /usr/local/bin/

linux-svnfile:/usr/local/redis # cp src/redis-cli /usr/local/bin/

linux-svnfile:/usr/local/redis # cp src/redis-trib.rb /usr/local/bin

linux-svnfile:/usr/local/redis # mkdir -p /usr/local/cluster/{7000..7005}

linux-svnfile:/usr/local/redis # vi redis.conf

daemonize yes

port 7000

cluster-enabled yes

cluster-config-file nodes.conf

cluster-node-timeout 5000

appendonly yes

linux-svnfile:/usr/local/redis # cp redis.conf ../cluster/7000

linux-svnfile:/usr/local/redis # cp redis.conf ../cluster/7001

linux-svnfile:/usr/local/redis # cp redis.conf ../cluster/7002

linux-svnfile:/usr/local/redis # cp redis.conf ../cluster/7003

linux-svnfile:/usr/local/redis # cp redis.conf ../cluster/7004

linux-svnfile:/usr/local/redis # cp redis.conf ../cluster/7005

这里需要注意的是文件名对应文件里端口的配置，例如 7001 文件下的 port 参数需要改为 7001，其他一样做修改。

linux-svnfile:/usr/local/redis # redis-server ../cluster/7000/redis.conf

linux-svnfile:/usr/local/redis # redis-server ../cluster/7001/redis.conf

linux-svnfile:/usr/local/redis # redis-server ../cluster/7002/redis.conf

linux-svnfile:/usr/local/redis # redis-server ../cluster/7003/redis.conf

linux-svnfile:/usr/local/redis # redis-server ../cluster/7004/redis.conf

linux-svnfile:/usr/local/redis # redis-server ../cluster/7005/redis.conf

linux-svnfile:/usr/local/redis # ps -ef | grep redis

像是上面在启动服务时需要注意切换到相应的配置文件的目录下，不然相应端口的服务无法启动，例如我之前在 /usr/local/redis 目录下启动后只有 7000 对应的服务启动了。

linux-svnfile:/usr/local/redis # redis-server ../cluster/7000/redis.conf

linux-svnfile:/usr/local/redis # redis-server ../cluster/7001/redis.conf

linux-svnfile:/usr/local/redis # redis-server ../cluster/7002/redis.conf

linux-svnfile:/usr/local/redis # redis-server ../cluster/7003/redis.conf

linux-svnfile:/usr/local/redis # redis-server ../cluster/7004/redis.conf

linux-svnfile:/usr/local/redis # redis-server ../cluster/7005/redis.conf

linux-svnfile:/usr/local/redis # ps -ef | grep redis

linux-svnfile:/usr/local/cluster #redis-cli -p 7000

127.0.0.1:7000>

删除 slave 节点

删除 master 节点

linux-svnfile:/usr/local/redis # redis-trib.rb reshard 127.0.0.1:7001

How many slots do you want to move (from 1 to 16384)? 5461

What is the receiving node ID? 42929649e533ec8aad7cbb81f204f04c849d4bff

Please enter all the source node IDs. 

  Type ‘all’ to use all the nodes as source nodes for the hash slots. 

  Type ‘done’ once you entered all the source nodes IDs. 

Source node #1: 6fe9561e605b7ee85e67a2557f7fb641f482afb4

Source node #2:done 

#Do you want to proceed with the proposed reshard plan (yes/no)? yes 

说明：

5461 表示要删除 master 所有的 slot 数量

What is the receiving node ID 是指将 7000 的 slot 迁移的节点 7001 的 node-id

Source node #1 是指要删除的 master 的 node-id

下面可以看到 7000 的 slot 为 0，而 7001 多了 4561

在删除 master 节点出现如下面所示的错误，是因为删除 master 节点之前没有删除 master 节点的 slave 节点。

上面是在单台机器上做的集群，下面展示两台机器上做集群，其实也很简单。

参考之前的环境编译源码到另一台机器

在两台机器上编辑配置文件

/usr/local/redis # vi redis.conf

daemonize yes

port 7000

cluster-enabled yes

cluster-config-file nodes.conf

cluster-node-timeout 5000

appendonly yes

cluster-config-file nodes-7001.conf

分别创建目录和文件

linux-svnfile:/usr/local/redis # mkdir -p/usr/local/cluster/{7001..7003}

localhost:/usr/local/redis # mkdir -p/usr/local/cluster/{8001..8003}

linux-svnfile:/usr/local/redis # cpredis.conf ../cluster/7001

linux-svnfile:/usr/local/redis # cpredis.conf ../cluster/7002

linux-svnfile:/usr/local/redis # cpredis.conf ../cluster/7003

localhost:/usr/local/redis # cp redis.conf../cluster/8001

localhost:/usr/local/redis # cp redis.conf../cluster/8002

localhost:/usr/local/redis # cp redis.conf../cluster/8003

修改对应目录的配置文件其中 port 和 cluster-config-file 分别对应各自的目录名，可使用 sed 命令做修改

sed -i “s/7001/7002/g”
