离线安装ruby
下载ruby-2.4.4并上传至服务器
https://cache.ruby-lang.org/pub/ruby/2.4/ruby-2.4.1.tar.gz
把包放到改目录下
tar -xvf ruby-2.4.4.tar.gz 
cd ruby-2.4.4
./configure --prefix=/usr/local/ruby
echo $?
make && make install
echo "PATH=$PATH:/usr/local/ruby/bin" >> /etc/profile
source /etc/profile
which ruby
/usr/bin/ruby
rm -rf /usr/bin/ruby
ln -s /usr/local/ruby/bin/ruby /usr/bin/ruby
　　[root@localhost ruby-2.4.4]# ruby -v
ruby 2.4.4p296 (2018-03-28 revision 63013) [x86_64-linux]
　　离线安装rubygems
下载rubygems-2.7.6.tgz并上传至服务器
https://rubygems.org/rubygems/rubygems-2.7.6.tgz
tar -xvf rubygems-2.7.6.tgz
chown -R root.root rubygems-2.7.6
mv rubygems-2.7.6 /usr/local/
cd /usr/local/rubygems-2.7.6/
ruby setup.rb 
echo "PATH=$PATH:/usr/local/rubygems-2.7.6" >> /etc/profile
source /etc/profile
查看当前版本

[root@localhost tools]# gem -v
2.7.6
-------------------------------------------------------------------------------------------------------------------
　　离线配置rubygems的redisapi
下载redis的gem并上传至服务器
https://rubygems.org/downloads/redis-3.3.0.gem
下载新的版本
https://rubygems.org/downloads/redis-4.0.2.gem
　　gem install -l redis-3.3.0.gem

[root@localhost tools]# gem list redis
*** LOCAL GEMS ***
redis (3.3.0)
如果安装是旧的版本
卸载
gem uninstal redis
　　安装

gem install -l redis-4.0.2.gem
[root@localhost tools]# gem list redis
*** LOCAL GEMS ***
redis (4.0.2)
　　离线安装tcl

下载tcl8并上传至服务器
https://sourceforge.net/projects/tcl/files/Tcl/8.6.0/
unzip tcl868-src.zip 
cd tcl8.6.8/unix/
./configure --prefix=/usr/local/tcl
echo $?
make
echo $?
make install
echo $?
make install-private-headers
ln -v -sf tclsh8.6 /usr/local/tcl/bin/tclsh
chmod -v 755 /usr/local/tcl/lib/libtcl8.6.so
echo "PATH=$PATH:/usr/local/tcl/bin" >> /etc/profile
source /etc/profile
　　创建用户

useradd qasuser
echo devops | passwd --stdin qasuser
　　下载redis安装包
http://download.redis.io/releases/redis-4.0.11.tar.gz
　　安装及配置

tar -xvf redis-4.0.11.tar.gz -C /app
chown -R qasuser.qasuser /app/redis-4.0.11
cd /app/redis-4.0.11
------------------------------------------------------------------------------------------------------------
如果因为上次编译失败，有残留的文件，做法如下：
[qasuser@localhost redis-4.0.11]$make distclean
------------------------------------------------------------------------------------------------------------
[qasuser@localhost redis-4.0.11]$ make
　　查看是否编译是否成功

[qasuser@localhost redis-4.0.11]$ echo $?
0
　　节点1上执行(172.16.8.13)

su - qasuser
mkdir /app/redis-4.0.11/redis-cluster
cd /app/redis-4.0.11/redis-cluster
mkdir {7000,7001,7002}

推荐做法：

[qasuser@localhost redis-cluster]$ pkill redis
[qasuser@localhost redis-cluster]$ pkill redis
[qasuser@localhost redis-cluster]$ pkill redis
　　
或者循环节点逐个关闭

[qasuser@localhost redis-cluster]$ for((i=0;i
