How to reinstall MySQL in Ubuntu

Due to Operation errors, I uninstalled Mysql under Ubuntu and had to reinstall it. After a long time, I did not install it, run # sudoapt-getremovemysql-server # sudoapt-getinstallmysql-server and then execute/usr/bin/mysqld_safe & amp; the following error is prompted: Can't connect tolocalmysqlserverthroughsock due to operation errors, after I uninstalled Mysql in Ubuntu, I had to reinstall it. After a long time, I didn't install it. Run

# Sudo apt-get remove mysql-server

# Sudo apt-get install mysql-server

Then run/usr/bin/mysqld_safe & the following error is prompted

Can't connect to local MySQL server through socket '/var/run/mysqld. sock' (2)

Indeed, there is no mysqld. sock file under/var/run/mysqld, and another error is:

/Etc/init. d/mysql: WARNING:/etc/mysql/my. cnf cannot be read. See README.Debian.gz

There is no my. cnf file under/etc. There is no way to do this, because the level is limited.

Finally, find a solution and execute

# Sudo apt-get install mysql-server mysql-common

Modify the mysql logon Password

# Sudo mysqladmin-u root-p password 'newpassword'

It mainly uses the mysql-common package, my. files such as cnf are from mysql-common, but before installation, it is best to clean all the mysql data that has been installed before. Other problems may occur during installation by name.
