Installing MySQL on CentOS using shell script - linux

Question

I am writing a script where I should install MySQL on my Centos hard disk when I run it.
I downloaded the following :
mysql-apt-config_0.8.5-1_all.deb
But I don't figure out how to install it from the shell script.
I am new to Linux and any help is appreciated !!

Answer 1

Since Centos is yum package manager just run the following commands to install MySql
If you are using Centos 7, you need to first add the repository as follows
wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
sudo rpm -ivh mysql-community-release-el7-5.noarch.rpm
yum update
To install MySql on Centos, we run
sudo yum install mysql-server
sudo systemctl start mysqld
Note: .deb files are only used for Debian based Linux Distros. Centos uses .rpm files.

Try to save following command in a shell file(extension with .sh) and run with sudo.
#!/bin/bash**strong text**
export http_proxy= $Write proxy
export https_proxy= $ write proxy
sudo -E yum -y update
sudo -E yum -y install wget
wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm
sudo rpm -ivh mysql-community-release-el7-5.noarch.rpm
sudo -E yum -y update
sudo -E yum -y install mysql-server
sudo systemctl start mysqld
sleep 1s
mysql -u root <<-EOF
UPDATE mysql.user SET Password=PASSWORD('123') WHERE User='root';
DELETE FROM mysql.user WHERE User='root' AND Host NOT IN ('localhost', '127.0.0.1', '::1');
DELETE FROM mysql.user WHERE User='';
DELETE FROM mysql.db WHERE Db='test' OR Db='test_%';
FLUSH PRIVILEGES;
EOF
