Redis-dump tool for data migration in clusters

Build the environment:

192.168.19.201 redis-cluster 6379 7001 7002 rvm redis-dump

192.168.19.202 redis-cluster 6379 7001 7002

192.168.19.203 redis-cluster 6379 7001 7002

Because you need to use rvm and gem tools to install redis-dump tools, you should install them in advance.

1. Install the dependency packages needed to install tools such as rvm in advance.

# yum-y install zlib zlib-devel pcre pcre-devel gcc gcc-c++ openssl openssl-devel libevent libevent-devel perl unzip net-tools wget curl

If the dependency above is not installed, an error will be reported.

two。 Install rvm

# gpg2-- keyserver hkp://keys.gnupg.net-- recv-keys D39DC0E3 download key

If the error is displayed

Then you can use the

Curl-sSL https://rvm.io/mpapis.asc | gpg2-- import-

Curl-sSL https://rvm.io/pkuczynski.asc | gpg2-- import-

# curl-L get.rvm.io | bash-s stable-this is another method of installation, but it is also possible

If an error is still displayed

# vim / etc/hosts

97.107.133.48 get.Rvm.io-add content

Just try again.

If the above content is displayed, the installation is successful.

Use the find /-name rvm-print command to view the path of the rvm installation

# find /-name rvm-print-if the result is displayed, the installation is successful

Make the configuration file effective

# source / etc/profile.d/rvm.sh

Download rvm dependency

# rvm requirements

# rvmsudo yum-y install gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel openssl-devel make bzip2 autoconf automake libtool bison iconv-devel

The above rvm has been installed!

Install ruby

# yum-y install automake autoconf libtool-dependencies required to install ruby

# yum-y install ruby rubygems ruby-devel-install ruby

Change the gem source

# gem source-- add https://gems.ruby-china.com-create a new gem Chinese local source

# gem source-l-View gem sources

# gem source-remove RubyGems.org | your community gem host-delete foreign official sources

Verify the version:

# rvm-version

# ruby-version

When you are ready, start upgrading the ruby you just used, otherwise ruby2.0.0 cannot install redis-dump

# rvm list known-you can view the installation versions supported by rvm

# rvm install "ruby-2.3.3"-ruby-2.3.3 is installed here (this step will be slow, please keep a good network connection)

It is said here that there are two vulnerabilities in the ruby3.0.0 version, which need to be patched manually

# ruby docs generate-ri

Verify that the version is updated

# ruby-version

Updated successfully!

Install redis-dump

# gem install redis-dump

Hint that

It probably means that you can install a higher version, and you can just follow the orders given by him.

# gem install redis-v 4.4.0

Install successfully, then execute the install redis-dump command

# gem install redis-dump

The above results will be successful.
