I am using a hosting server that doesn't provide me with a root account.
They don't provide me with an installation service of database.
The server is Red Hat Enterprise Linux Server release 6.1 (Santiago) x86_64.
I tried to download and install MySQL 5.7.10, but it shows me errors regarding to InnoDB setup as below:
[hoge#blackett mysql]$ ./bin/mysqld --initialize --basedir=/home/hoge/mysql --character-set-server=utf8

I also did the following:
cp ./support-files/my-default.cnf ~/my.cnf
I tried the following command, but it gives me the same errors:
[hoge#blackett mysql]$ ./bin/mysqld --initialize --character-set-server=utf8 --basedir=/home/hoge/mysql --defaults-file=/home/hoge/my.cnf
I wrote the following in my.cnf, but doesn't solve the error:
innodb_use_native_aio = 0
I have no ideas to solve them.
Could you please help me?
Maybe...
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.

I resolved the issue myself.
The document https://dev.mysql.com/doc/refman/5.7/en/data-directory-initialization-mysqld.html says
the --defaults-file option must be first
When I typed ./bin/mysqld --defaults-file=/home/hoge/my.cnf --initialize --character-set-server=utf8 --basedir=/home/hoge/mysql, the option file was recognized.
Another solution is to specify --innodb_use_native_aio=0 option directly without using the option file, my.cnf, as below:
./bin/mysqld --initialize --basedir=/home/utpsy/mysql --character-set-server=utf8 --innodb_use_native_aio=0

This is going to be a long one. Please read.
I created an new Azure Ubuntu 18.04 with a 1 TB drive. Setup went fine. Then I installed MySql server using this link. Everything went fine. I was able to start up the mysql with no issues.
My next step was to change the data directory path. I followed this guide. The only difference I changed from the guide was the sudo rsync -av /var/lib/mysql /mnt/MYSQLDATA. When I ran that command, it didn't do anything. Nothing copied over. I replace it with cp * -r /mnt/MYSQLDATA to copy everything over.
I followed the guide to the end. I changed the cnf for mysql /etc/mysql/mysql.conf.d/mysqld.cnf to read:
datadir = /mnt/MYSQLDATA
Next, I changed the alias also sudo nano /etc/apparmor.d/tunables/alias:
`# alias /var/lib/mysql/ -> /mnt/MYSQLDATA/`,
I figured I had to change the [/etc/apparmor.d/usr.sbin.mysqld][3] config. This is the code I used:
# Allow data dir access
/mnt/MYSQLDATA/ r,
/mnt/MYSQLDATA** rwk,
Restarted the apparmor. Everything looked like it was set. I even went to make sure that mysql was the owner of the folder path, so I can chown -R mysql:mysql /mnt/MYSQLDATA. Now it was time to restart the service and it doesnt restart. I keep getting
Job for mysql.service failed because the control process exited with an error code. See "systemctl status mysql.service" and "journalctl -xe" for details.

I have no idea what I did wrong and where it went wrong. In the journalctl -xe it just shows mysql.services: control process exited, code=exited status=1 or mysql.services: start request repeated too quickly. I am pulling my hair out trying to figure out what went wrong. Please help.
I was also running into similar problem.
The main problem was /mnt/mysqldisk/mysql the mysqldisk was created by my user so in the /var/log/syslog it was complaining it could not write to mysql directory.
I changed the permissions to mysql:mysql using shown on the directory. that should solve your problem
The easiest solution I found is using softlink
This is the final solution I did and you don't need to go through any complicated steps
-stop the mysql server
-sudo cp -a /var/lib/mysql /mnt/mysqldisk/mysql
-sudo mv /var/lib/mysql /var/lib/mysql.bak
` #create a soft link that points to the new mount mysql directory
sudo ln -s /mnt/mysqldisk/mysql/ /var/lib/mysql
Start the mysql service and check it comes up.
you do not need to do any change to /etc/mysql/mysql.conf.d/mysqld.cnf or any Alias etc.
This since to the mysql it looks as if mysql is still at the same place and the original config will still be able to access the new location from the soft link.
This is on ubuntu 18.04 LTS
MariaDB has worked fine but is now failing to run on boot up. I have uninstalled and it then reinstalled it and this does not fix anything.

A "/etc/my.cnf" from another install may interfere with a Homebrew-built

MySQL is configured to only allow connections from localhost by default
To have launchd start mariadb now and restart at login:
brew services start mariadb

I realise I probably have to add some connector but I don't know where and how.
I use MySQL 5.7 and CentOS 7.2.
At first, my datadir configuration in my.cnf is /var/lib/mysql
Now I want to change datadir.
I hava try two ways:
First, I copy all files and directories in /var/lib/mysql to /home/data, and run chown -R mysql:mysql /home/data. But when I run systemctl start mysqld, I get error message:

Second, I move /var/lib/mysql to /home and run ln -s /home/mysql mysql in /var/lib directory. When I run systemctl start mysqld, I get error message:

How can I deal with it?
this problem is about subdir permission
and you should edit this file /etc/apparmor.d/local/usr.sbin.mysqld
/data/ r,
/data/** rwk,
do not forgot, and you should find same command at centos, like this
sudo service apparmor reload
about this problem at ubuntu sys, and see link

happy day, baddy
I am working on a *nix machine and I don't have root privileges.
I am trying to install mysql locally using this blogpost: http://www.thedance.net/~roth/TECHBLOG/localMySQL.html
However, I am stuck at scripts/mysql_install_db command.
When I run this command I get the following error:
FATAL ERROR: Neither host 'server.address.com' nor 'localhost' could be looked up with
/usr/bin/resolveip
Please configure the 'hostname' command to return a correct hostname.
If you want to solve this at a later stage, restart this script
with the --force option
On further digging, I found that adding --basedirresolves this issue. But then it generates the following errors:

It is trying to access system level folders and because of the permission issues it is failing. How do I install it locally. And how do I setup the hostname?
The problem lies on the following line in log:
[ERROR] Can't find messagefile '/usr/share/mysql/errmsg.sys'
To solve it, add this flag to your command:
--lc-messages-dir="/some/path/you/can/access/without/sudo/"
