How to install MySQL-5.5 on Ubuntu
I had a legacy application where MySQL-5.5 was required and i struggle to install it on my machine at that time, so I decided to write down the steps hoping it can help someone else like me in the future.
MySQL Download URL
- Uninstall any existing version of MySQL
sudo rm /var/lib/mysql/ -R
sudo rm /etc/mysql/ -R
- Automatically uninstall mysql
sudo apt-get autoremove mysql* --purge
sudo apt-get remove apparmor
- Download version 5.5.51 from MySQL site
wget https://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.56-linux-glibc2.5-x86_64.tar.gz
sudo groupadd mysql
- Add mysql (not the current user) to mysql user group
sudo useradd -g mysql mysql
sudo tar -xvf mysql-5.5.56-linux-glibc2.5-x86_64.tar.gz
sudo mv mysql-5.5.56-linux-glibc2.5-x86_64 /usr/local/
- Create mysql folder in /usr/local by moving the untarred folder
cd /usr/local
sudo mv mysql-5.5.56-linux-glibc2.5-x86_64 mysql
- set MySql directory owner and user group
cd mysql
sudo chown -R mysql:mysql *
- Install the required lib package (works with 5.6 as well)
sudo apt-get install libaio1
- Execute mysql installation script
sudo scripts/mysql_install_db --user=mysql
- Set mysql directory owner from outside the mysql directory
sudo chown -R root .
- Set data directory owner from inside mysql directory
sudo chown -R mysql data
- Copy the mysql configuration file
sudo cp support-files/my-medium.cnf /etc/my.cnf
sudo bin/mysqld_safe --user=mysql &
sudo cp support-files/mysql.server /etc/init.d/mysql.server
sudo bin/mysqladmin -u root password '[your new password]'
- Add mysql path to the system
sudo ln -s /usr/local/mysql/bin/mysql /usr/local/bin/mysql
- Reboot!
- Start mysql server
sudo /etc/init.d/mysql.server start
sudo /etc/init.d/mysql.server stop
sudo /etc/init.d/mysql.server status
sudo update-rc.d -f mysql.server defaults
- *Disable mysql on startup (Optional)
sudo update-rc.d -f mysql.server remove
REBOOT!
Now login using below command, start mysql server if it's not running already
mysql -u root -p
