【问题描述】：

我正在尝试按照这些说明在 s390 (z/Linux) 上构建 mariaDB mariaDB Instructions。抱歉，我不是 DBA 或 SA。

但我卡在了“3.7 创建数据库并将测试数据填充到数据库”这一步中

sudo scripts/mysql_install_db --user=mysql

这是我得到的错误：

root@tdpvld01:/usr/local/mysql> sudo scripts/mysql_install_db --user=mysql

Installation of system tables failed!  Examine the logs in
/var/lib/mysql for more information.

The problem could be conflicting information in an external
my.cnf files. You can ignore these by doing:

    shell> scripts/mysql_install_db --defaults-file=~/.my.cnf

You can also try to start the mysqld daemon with:

    shell> ./bin/mysqld --skip-grant-tables --general-log &

and use the command line tool ./bin/mysql
to connect to the mysql database and look at the grant tables:

    shell> ./bin/mysql -u root mysql
    mysql> show tables;

Try 'mysqld --help' if you have problems with paths.  Using
--general-log gives you a log in /var/lib/mysql that may be helpful.

按照一些论坛的建议，我尝试运行 mysql_upgrade。但是得到了这个错误：

root@tdpvld01:/usr/local/mysql/bin> ./mysql_upgrade
Version check failed. Got the following error when calling the 'mysql' command line client
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
FATAL ERROR: Upgrade failed

任何建议将不胜感激。

【问题讨论】：

你没有提到你在 Z 上运行的是哪个 Linux 发行版；但是您可能不需要编译任何东西吗？ rpmfind.net/linux/rpm2html/search.php?query=mariadb
抱歉，这是 Red Hat Enterprise Linux Server release 7.3 (Maipo) 我找到的 Red Hat 的最新 RPM 版本是 5.5
也许你在调用mysql_upgrade时需要连接参数（user/pwd/port/...）？

【解决方案1】：

解决方案相当简单。
该 s390 上有一个以前的 mysql/mariadb rpm 安装。我卸载了 mariadb RPM，但离开了 mysql。
似乎当我编译 mariadb 时，它覆盖了 mysql 安装并产生了该错误。
我卸载了所有东西，再次重新编译，现在它工作正常。
