openproject configure引发“错误1045（28000）：用户'root'@'localhost'的访问被拒绝（使用密码：是）”？

Question

根据CentOS 7文档（https://www.openproject.org/download-and-installation/#installation）安装了openproject，并且在运行sudo openproject configure之后，得到如下所示的错误输出：

➜  ~ sudo openproject configure

以前从未使用过MariaDB，但经过一些基本检查（安装在https://www.digitalocean.com/community/tutorials/how-to-reset-your-mysql-or-mariadb-root-password之后）

➜  ~ mysqladmin -u root -p version

（密码只是空白），该数据库似乎正在运行并且可以访问。删除并重新安装mariadb-server软件包似乎也无法更改行为。以前从未使用过openproject或mysql / mariadb，因此，任何有关此处可能发生的情况的建议都将不胜感激。

Answer 1

您是否在配置步骤中选择了Install and configure MySQL server locally？

如果是，则软件包应自动配置一个随机的MySQL root密码，该密码存储在mysql/root_password的密钥/etc/openproject/installer.dat下。如果仍然可以使用空密码访问数据库，则安装程序无法正确设置密码。 It appears to take input from urandom。

您可以尝试在MySQL密码提示中按Enter的同时运行以下命令：

mysqladmin -u root -p password "<Create and insert a random password here>"

然后替换mysql/root_password处/etc/openproject/installer.dat处的值。
