redis集群离线安装环境搭建过程

　　本文是继上次redis集群重新整理的离线搭建环境，关于前期的redis集群准备工作参考我另一篇博客:

http://www.cnblogs.com/qlqwjy/p/8566573.html

　　由于集群搭建redis的安装环境甚是复杂，在这里新开一篇记录搭建安装环境的过程。

离线安装需要准备的软件:下载地址在文章最后贴出:

　　

一、安装ruby运行环境

1.将ruby-2.3.7.tar.gz上传到服务器

2.解压文件

tar -zxvf ./ruby-2.3.7.tar.gz

3.编译安装

# 配置
./configure
#编译
make
#编译安装
make install

4.测试ruby运行环境

[root@iz2ze46xi6pjjj69ailg9lz ruby-2.3.7]# ruby -v
ruby 2.3.7p456 (2018-03-28 revision 63024) [x86_64-linux]

二、安装redis接口

1.直接安装报错

[root@iz2ze46xi6pjjj69ailg9lz ruby-2.3.7]# gem install redis
ERROR:  Loading command: install (LoadError)
        cannot load such file -- zlib
ERROR:  While executing gem ... (NoMethodError)
    undefined method `invoke_with_build_args' for nil:NilClass

2.修改gem镜像

[root@iz2ze46xi6pjjj69ailg9lz ruby-2.3.7]# gem sources -l
*** CURRENT SOURCES ***

https://rubygems.org/
[root@iz2ze46xi6pjjj69ailg9lz ruby-2.3.7]# gem sources -a  http://gems.ruby-china.org/　　
ERROR:  While executing gem ... (NameError)
    uninitialized constant Gem::RemoteFetcher::Zlib

发现报错，需要安装zlib

3.安装zlib

(1)将zlib-1.2.11.tar.gz上传到服务器

(2)解压安装

mkdir zlib
tar -vxf zlib-1.2.11.tar.gz
cd zlib-1.2.11/
./configure --prefix=/usr/local/zlib
make
make install

(3)编译 ruby 中的zlib

进入到/opt/ruby/ruby-2.3.7/ext/zlib目录下:

[root@iz2ze46xi6pjjj69ailg9lz 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

接着编译安装

make
make install

4.接着继续修改gem镜像地址安装redis接口

• 修改gem镜像

gem sources -a  http://gems.ruby-china.org/

• 查看镜像

[root@iz2ze46xi6pjjj69ailg9lz ruby]# gem source -l
*** CURRENT SOURCES ***

https://rubygems.org/
http://gems.ruby-china.org/

• 离线安装redis接口(前提是下载好redis-3.2.1.gem)

[root@iz2ze46xi6pjjj69ailg9lz ruby]# gem install -l redis-3.2.1.gem #安装本地的redis接口
Successfully installed redis-3.2.1
Parsing documentation for redis-3.2.1
Installing ri documentation for redis-3.2.1
Done installing documentation for redis after 1 seconds
1 gem installed

至此redis集群的环境基本算是安装完成

三、启动集群进行测试

1.将/usr/local/redis-4.0.2/src目录下的redis-trib.rb文件拷贝到/usr/local/redis/bin/目录下

[root@iz2ze46xi6pjjj69ailg9lz src]# pwd
/usr/local/redis-4.0.2/src
[root@iz2ze46xi6pjjj69ailg9lz src]# ls | grep rb
redis-trib.rb
[root@iz2ze46xi6pjjj69ailg9lz src]# cp ./redis-trib.rb /usr/local/redis/bin/redis-trib/
cp: cannot create regular file 鈥usr/local/redis/bin/redis-trib/鈥 Not a directory
[root@iz2ze46xi6pjjj69ailg9lz src]# cp ./redis-trib.rb /usr/local/redis/bin/
[root@iz2ze46xi6pjjj69ailg9lz src]# ls /usr/local/redis/bin/ | grep rb
redis-trib.rb

2.进入/usr/local/redis/bin/目录下创建集群

[root@iz2ze46xi6pjjj69ailg9lz bin]# ./redis-trib.rb create --replicas 1 127.0.0.1:7000 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005
>>> Creating cluster
[ERR] Node 127.0.0.1:7000 is not empty. Either the node already knows other nodes (check with CLUSTER NODES) or contains some key in database 0.

错误:

将集群目录下的nodes-700x.conf和appendonly-700x.aof文件删除后重启集群

...删除文件操作...
[root@iz2ze46xi6pjjj69ailg9lz redis]# cd cluster/
[root@iz2ze46xi6pjjj69ailg9lz cluster]# ls
redis7000  redis7001  redis7002  redis7003  redis7004  redis7005
[root@iz2ze46xi6pjjj69ailg9lz cluster]# cd ..
[root@iz2ze46xi6pjjj69ailg9lz redis]# ./startcluster.sh #启动6个redis

3.登录集群的一个节点进行测试:
