1.Ruby installation. Note: do not use the latest 2.2 or 2.3 version of ruby. Some components may not be installed

yum -y install  openssl-devel gcc
wget https://ruby.taobao.org/mirrors/ruby/2.1/ruby-2.1.7.tar.gz
tar zxf ruby-2.1.7.tar.gz
cd ruby-2.1.7
./configure --prefix=/usr/local/ruby2.1.7
make && make install
echo 'export PATH=/usr/local/ruby2.1.7/bin:$PATH'>>/etc/profile
source /etc/profile

2.RubyGems tool installation

wget http://rubygems.global.ssl.fastly.net/rubygems/rubygems-2.6.2.tgz
tar zxf rubygems-2.6.2.tgz
cd rubygems-2.6.2
ruby setup.rb

3. The replacement of gem source is also due to the problem of network environment, so it is very slow to visit the official source

gem sources --add https://ruby.taobao.org/ --remove https://rubygems.org/
gem sources -l

4.Grokbug installation

mkdir /usr/local/grokbug
cd /usr/local/grokbug
wget https://codeload.github.com/nickethier/grokdebug/zip/master
unzip master
mv grokdebug-master/* .
rm -rf grokdebug-master/

5. Install Ruby components (the following components have corresponding requirements for the version). Check the missing components. Execute the following command in / usr/local/grokbug, and you will be prompted about the components and the corresponding version

ruby config.ru
