1)最便宜的$22.88/year

6)怎么安装证书
怎么生成证书:https://www.namecheap.com/support/knowledgebase/article.aspx/9446/14/generating-csr-on-apache--opensslmodsslnginx--heroku
Once all the requested information is filled in, you should have *.csr and *.key files in the folder where the command has been run.
在namespace中,新用户才需要重复以下步骤,续SSL是不同的操作流程(参考namespace.com):
A)生成CSR (Certificate signing request),这个在激活的时候是由用的;
B)激活SSL
C)然后把SSL安装到Nginx上
