mysql - 没有 root 帐户无法在服务器上安装 MySQL 5.7

Question

我使用的托管服务器不向我提供根帐户。他们不给我提供数据库安装服务。服务器是 Red Hat Enterprise Linux Server 版本 6.1 (圣地亚哥) x86_64。

我尝试下载并安装 MySQL 5.7.10，但它显示了有关 InnoDB 设置的错误，如下所示:

[hoge@blackett mysql]$ ./bin/mysqld --initialize --basedir=/home/hoge/mysql --character-set-server=utf8

我还做了以下事情:

cp ./support-files/my-default.cnf ~/my.cnf

我尝试了以下命令，但它给了我同样的错误:

[hoge@blackett mysql]$ ./bin/mysqld --initialize --character-set-server=utf8 --basedir=/home/hoge/mysql --defaults-file=/home/hoge/my.cnf

我在 my.cnf 中编写了以下内容，但没有解决错误:

innodb_use_native_aio = 0

我没有办法解决这些问题。你能帮我一下吗？

也许...

On Linux systems, running multiple MySQL servers (typically more than 12) with default settings for innodb_read_io_threads, innodb_write_io_threads, and the Linux aio-max-nr setting can exceed system limits. Ideally, increase the aio-max-nr setting; as a workaround, you might reduce the settings for one or both of the MySQL configuration options.
