Redis Cluster 运维环境安装记录

痛定思痛。 2022-05-19 00:40 248阅读 0赞

### 前言 ###

之前安装Redis Clutser模式遇到很多坑，一直没有总结。最近有时间，总结一下，相关的内容。

*  Redis 安装(略)
 *  GCC安装
 *  Ruby的安装
 *  Ruby内 Redis.gem的安装
 *  Redis Cluster的安装配置和启动

本文使用的资源，可在我的Github项目[https://github.com/SeanYanxml/bigdata/tree/master/redis][https_github.com_SeanYanxml_bigdata_tree_master_redis] 目录下可以找到。  
PS: (如果觉得项目不错，可以给我一个Star。)

--------------------

### 详细介绍 ###

*  Redis安装 & GCC安装

#GCC一般自带`GCC -v`检查
    #Redis 安装
    wget http://download.redis.io/releases/redis-4.0.6.tar.gz
    tar xzf redis-4.0.6.tar.gz
    # cd redis-4.0.6
    # make 
    # 有时使用 make MALLOC=libc

--------------------

#### Ruby 安装 & Gem库安装 ####

*  使用redis-trib.rb脚本，缺少ruby。

[root@cpic-redis3-78 src]# ./redis-trib.rb --help
    /usr/cpic/apps/ruby/lib/ruby/2.4.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- redis (LoadError)
        from /usr/cpic/apps/ruby/lib/ruby/2.4.0/rubygems/core_ext/kernel_require.rb:55:in `require'
        from ./redis-trib.rb:25:in `<main>'

*  安装ruby

tar -zxvf ruby-2.4.3.tar.gz
    cd ruby-2.4.3
    ./configure --prefix=/usr/cpic/apps/ruby
    make & make install

注意Ruby的版本一般与GCC的内核版本有关。不应过高或过低，不然会导致安装错误。

*  安装redis的ruby库。

[root@cpic-redis3-78 apps]# gem install redis-4.0.gem
    ERROR:  Loading command: install (LoadError)
        cannot load such file -- zlib
    ERROR:  While executing gem ... (NoMethodError)
        undefined method `invoke_with_build_args' for nil:NilClass

*  安装ruby的zlib库

[root@cpic-redis3-78 ext]# cd zlib/
    [root@cpic-redis3-78 zlib]# ls
    depend  extconf.rb  Makefile  mkmf.log  zlib.c
    [root@cpic-redis3-78 zlib]# ruby ./extconf.rb
    checking for deflateReset() in -lz... no
    checking for deflateReset() in -llibz... no
    checking for deflateReset() in -lzlib1... no
    checking for deflateReset() in -lzlib... no
    checking for deflateReset() in -lzdll... no
    checking for deflateReset() in -lzlibwapi... no
    [root@cpic-redis3-78 zlib]# make
    [root@cpic-redis3-78 zlib]# make install

*  安装zlib库

rpm -ivh zlib-devel-1.2.7-17.el7.x86_64.rpm

depend  extconf.rb  Makefile  mkmf.log  zlib.c
    [root@cpic-redis3-78 zlib]# ruby ./extconf.rb
    checking for deflateReset() in -lz... yes
    checking for zlib.h... yes
    checking for crc32_combine() in zlib.h... yes
    checking for adler32_combine() in zlib.h... yes
    checking for z_crc_t in zlib.h... yes
    creating Makefile

make: * No rule to make target /include/ruby.h', needed byzlib.o’. Stop
    #MakeFile文件加上
    ＃ 加上
    top_srcdir=/usr/cpic/apps/ruby-2.4.3

[root@cpic-redis3-78 apps]# gem install redis-4.0.1.gem
    ERROR:  While executing gem ... (Gem::Exception)
        Unable to require openssl, install OpenSSL and rebuild ruby (preferred) or use non-HTTPS sources
    
    ＃选择本地安装
     gem install -l redis-4.0.1.gem

注意，非本地安装需要安装OpenSSL组件。并且，阿里和网易的Gem仓库都已经不再维护了。需要去[https://rubygems.org/gems/redis/versions/4.0.1][https_rubygems.org_gems_redis_versions_4.0.1]进行查找。

*  安装成功

[root@cpic-redis3-78 src]# ./redis-trib.rb
    Usage: redis-trib <command> <options> <arguments ...>
    
      create          host1:port1 ... hostN:portN
                      --replicas <arg>   check           host:port
      info            host:port
      fix             host:port
                      --timeout <arg>   reshard         host:port
                      --from <arg>                   --to <arg>                   --slots <arg>                   --yes                   --timeout <arg>                   --pipeline <arg>   rebalance       host:port
                      --weight <arg>                   --auto-weights                   --use-empty-masters                   --timeout <arg>                   --simulate                   --pipeline <arg>                   --threshold <arg>   add-node        new_host:new_port existing_host:existing_port
                      --slave                   --master-id <arg>   del-node        host:port node_id
      set-timeout     host:port milliseconds
      call            host:port command arg arg .. arg
      import          host:port
                      --from <arg>                   --copy                   --replace   help            (show this help)
    
    For check, fix, reshard, del-node, set-timeout you can specify the host and port of any working node in the cluster.

# 如果集群之前就配置密码的，需要去/usr/lib/ruby/gems/1.8/gems/redis-3.2.1/lib/redis/client.rb内修改密码那一行的字段。
    
    #自己个人的地址可以通过如下命令进行查找
    cd /
    find -name "*client.rb*"
    
    # 需要修改密码的地方。
    class Redis
      class Client
    
        DEFAULTS = {
          :url => lambda { ENV["REDIS_URL"] },
          :scheme => "redis",
          :host => "127.0.0.1",
          :port => 6379,
          :path => nil,
          :timeout => 5.0,
          # 特别注意，改成集群密码即可。
          :password => "admin",
          :db => 0,
          :driver => nil,
          :id => nil,
          :tcp_keepalive => 0,
          :reconnect_attempts => 1,
          :inherit_socket => false
        }
     }
