Centos 部署rails应用遇到的一些问题

Centos 部署rails应用遇到的一些问题

1. 在centos中安装Nokogiri是遇到问题

libxml2 is missing.  please visit <http://nokogiri.org/tutorials/installing_nokogiri.html>

 

解决方法如下:

$ sudo yum install -y libxml2 libxml2-devel libxslt libxslt-devel

　　

2. openssl 问题

$ ...   :in `require': no such file to load -- openssl (LoadError)

解决方法如下:

下载1.9.2源文件,执行以下命令

$ cd ~/Downloads/ruby-1.9.2-p180/ext/openssl (assuming you extracted the ruby tar to ~/Downloads)
$ ruby extconf.rb && make && sudo make install

　　

If you’ve compiled Ruby from source, you might get this error when executing script/console:

 

/usr/local/lib/ruby/1.8/irb/completion.rb:10:in `require': no such file to load -- readline (LoadError)

 

One way of fixing this is to compile readline, which is distributed along with the Ruby source:

 

 cd /opt/src/ruby-1.8.5-p2/ext/readline
 ruby extconf.rb
 make
 sudo make install
