Google found an official solution to the patch, that is, replace two SSL library files, the attachment for the patch file package download address
See: https://bugs.ruby-lang.org/projects/ruby-trunk/repository/revisions/41808
Workaround:

The code is as follows

Copy Code

# CD ruby-2.0.0-p247 # wget HTTPS://BUGS.RUBY-LANG.ORG/PROJECTS/RUBY-TRUNK/REPOSITORY/REVISIONS/41808/RAW/EXT/OPENSSL/OSSL_PKEY_EC.C # wget HTTPS://BUGS.RUBY-LANG.ORG/PROJECTS/RUBY-TRUNK/REPOSITORY/REVISIONS/41808/RAW/TEST/OPENSSL/TEST_PKEY_EC.RB # MV EXT/OPENSSL/OSSL_PKEY_EC.C Ext/openssl/ossl_pkey_ec.c.bak # CP OSSL_PKEY_EC.C ext/openssl/ # MV Test/openssl/test_pkey_ec.rb Test/openssl/test_pkey_ec.rb.bak # CP TEST_PKEY_EC.RB test/openssl/

Recompile:

The code is as follows	Copy Code
# Make && make install

Four. Add Ruby command set to System environment variable

The code is as follows	Copy Code
# echo "path= $PATH:/usr/local/ruby/bin;export PATH" >>/etc/profile # Source/etc/profile

Five. Check Ruby version

The code is as follows	Copy Code
# ruby-v —————————————————————————— Ruby 2.0.0p247 (2013-06-27 revision 41674) [X86_64-linux] —————————————————————————— # Gem--version —————————————————————————— 2.0.3 www.111cn.net —————————————————————————— # IRB —————————————————————————— IRB (main):001:0> 3+5 => 8 IRB (main):002:0> puts "Hello world!"
