I use Scrapy,
i tried to install mysql by brew install mysql
but i have this warning:
Warning: mysql-5.7.12 already installed
if mysql is already installed, why i can't see it in /etc/init.d/mysql
Is it possible you had previously not fully removed mysql and its components? One method of totally removing mysql from your system would be via the terminal. I found a pretty cut and dry way over at coolestguidesontheplanet:
sudo rm -rf /usr/local/mysq*
sudo rm /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
Navigate to then Edit /etc/hostconfig and remove the line with MYSQLCOM=-YES/NO-
rm -rf ~/Library/PreferencePanes/MySQL*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /private/var/db/receipts/*mysql*
be sure to investigate as you go along and try to share what the issue was.

I need to install an older version of mysql (5.7) and remove current (8.0) from my system. I've tried multiple possible ways for the same but I can still output after running mysql --version
mysql Ver 8.0.27 for macos11.6 on x86_64 (Homebrew)
Ran below commands but no help:
$ sudo rm /usr/local/mysql
$ sudo rm -rf /usr/local/mysql*
$ sudo rm -rf /Library/StartupItems/MySQLCOM
$ sudo rm -rf /Library/PreferencePanes/My*
edit /etc/hostconfig and remove the line MYSQLCOM=-YES-
$ rm -rf ~/Library/PreferencePanes/My*
$ sudo rm -rf /Library/Receipts/mysql*
$ sudo rm -rf /Library/Receipts/MySQL*
$ sudo rm -rf /private/var/db/receipts/*mysql*
$ sudo rm -rf /var/db/receipts/com.mysql.mysql*
I had installed by downloading the dmg image of the installer so removing using brew doesn't help. Any leads would help. Thanks.
I followed another stackoverflow post to completely uninstall all instances of MySQL (I had 5..)
$ sudo rm /usr/local/mysql
$ sudo rm -rf /usr/local/mysql*
$ sudo rm -rf /Library/StartupItems/MySQLCOM
$ sudo rm -rf /Library/PreferencePanes/My*
edit /etc/hostconfig and remove the line MYSQLCOM=-YES-
$ rm -rf ~/Library/PreferencePanes/My*
$ sudo rm -rf /Library/Receipts/mysql*
$ sudo rm -rf /Library/Receipts/MySQL*
$ sudo rm -rf /private/var/db/receipts/*mysql*
$ sudo rm -rf /var/db/receipts/com.mysql.mysql*
And reinstalled using
brew install mysql
but when I start the server, I have to put in the old root user password, which means it's still storing the passwords somewhere.
Brew prompted me change the password which I did, and then I got this error
... Failed! Error: File './mysql/user.MYD' not found (Errcode: 2 - No such file or directory)
So clearly mysql hasn't been completely uninstalled.
Ended up solving it by running
ps -ax | grep mysql
then going to each of the folders and removing any mysql data
then uninstalling XAMPP
then restarting computer
then
brew install mysql
I am trying to do a fresh install of Mac OSX LAMP and running the command
mysql_secure_installation
I have inputting the root password and I have to now input a new password when I'm hit with this error, has anyone got any experience with this?
Re-enter new password:
... Failed! Error: File './mysql/user.MYD' not found (Errcode: 13 - Permission denied)
Please retry to completely remove mysql by executing:
brew remove mysql
brew cleanup
sudo rm /usr/local/mysql
sudo rm -rf /usr/local/var/mysql
sudo rm -rf /usr/local/mysql*
sudo rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
edit /etc/hostconfig and remove the line MYSQLCOM=-YES-
rm -rf ~/Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /private/var/db/receipts/*mysql*
And then restart your computer to make sure that all the processes have been killed.
Then execute these commands to install MySQL:
brew update
brew install mysql
unset TMPDIR
mysql_install_db --verbose --user='<your-username>' --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
mysql.server start
This should do the trick.
I think there was a corruption within the install and decided to delete and use brew to install and all is now well! Follow these steps
Open a terminal window
Use mysqldump to backup your databases to text files!
Stop the database server
sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
edit /etc/hostconfig and remove the line MYSQLCOM=-YES-
rm -rf ~/Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /private/var/db/receipts/*mysql*
Then installed via Brew
brew install mysql
I just wanna confirm wheather MySql is intalled in my mac machine or not. Actually, during its installation process I just messed up with the password configuration and after that I tried to reset its password but all to vain and I finally decided to uninstall it and do the installtion again from start. But before installing it again I just wanna confirm wheather the previous installation got cleared properlly or not. For unintalling mysql I have used following commands
sudo rm /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
edit /etc/hostconfig and remove the line MYSQLCOM=-YES-
rm -rf ~/Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /private/var/db/receipts/*mysql*
Execute the following command. If it says "command not found" it's not installed.
mysql -v
Im currently using MAMP, but I installed the Mysql standalone before. So how can I uninstall that mysql and make sure it doesn't affect on the MAMP MySQL. Thanks.
