启动jekyll服务器时的错误

Question

我的云服务器是 Ubuntu 14，在我安装 jekyll 并像 sudo jekyll serve --port 80 --host 'my server ip address' 一样启动它后，它显示如下错误：

   Configuration file: /home/ubuntu/mydomain.com/_config.yml
   Deprecation: You appear to have pagination turned on, but you haven't included the `jekyll-paginate` gem. Ensure you have `gems: [jekyll-paginate]` in your configuration file.
        Source: /home/ubuntu/mydomain.com
   Destination: /home/ubuntu/mydomain.com/_site
   Incremental build: disabled. Enable with --incremental
   Generating...
                done in 1.177 seconds.
   Deprecation: You appear to have pagination turned on, but you haven't     included the `jekyll-paginate` gem. Ensure you have `gems: [jekyll-paginate]` in your configuration file.
   Auto-regeneration: enabled for '/home/ubuntu/mydomain.com'
   Configuration file: /home/ubuntu/mydomain.com/_config.yml
   jekyll 3.1.2 | Error:  Cannot assign requested address - bind(2) for 'host:port'

那么我该如何解决这个问题。

想定时把自己的github页面拉到云服务器上，发现有人这样干的

crontab -e 

*/2 * * * * cd ~/mydomain.com/; git pull >> /tmp/github_blog_pull_record.log 2>&1;

我不知道*/2 * * * * cd ~/mydomain.com/; git pull >> /tmp/github_blog_pull_record.log 2>&1; 是什么意思？

Answer 1

问题 1：您已经有一个使用 80 端口的进程，请尝试更改您的 jekyll serve 端口 sudo jekyll serve --port 81 --host 'my server ip address'。注意：为什么用 sudo 运行 jekyll？一点都不安全！

问题 2：*/2 * * * * cd ~/mydomain.com/; ... 是一个 cron task，它将在每天 02:00 拉动您的 github 存储库。

注意：最好一次问一个问题。
