Solo 开发指南

真的呀，有的话那就意味着不需要用 mysql 了。那才爽，博客的便利性！
对了。支持后台进行备份操作吗？还是需要 code 呢？

按照上述步骤，git clone 后用 mvn jetty:run 运行报错，错误信息应该是说连接 mysql 失败，难道要先装 mysql 吗？不是说集成了 mysql 在项目发布的文件里吗？第一次尝试 solo，谁能帮忙解答一下？谢谢。打印信息如下：

请教一下，使用 injigen 主题的时候，点击首页的动态会报一个错误。我没有找到解决办法。、

改完 mysql 密码后我们开始手动建库。

mysql> create database solo;
Query OK, 1 row affected (0.01 sec)

接下来启动 solo 博客系统，大功告成。

mvn jetty:run

用 http://【你的服务器IP】:8080/ 登录系统，初始化博客。
