I am setting up a new vagrant box for a NodeJS project. For the database I will be using MySQL. I have setup a provisioning script to install everything I need and it all works great apart from accessing MySQL from the host machine (Using Sequel Pro). I have it working but I have to edit the /etc/mysql/my.cnf file in order to comment out the bind-address line.
Is there anyway to do this on the command line so I can add it to the provisioning script? If this is possible then any other dev that I share the project with would only need to do vagrant up and have everything ready to go.
Below are the parts of my script relevant to the MySQL setup:
#!/bin/bash
# Variables
DBHOST=localhost
DBNAME=vagrant
DBUSER=vagrant
DBPASSWD=test123
# Update packages
apt-get update
# Install MySQL
debconf-set-selections <<< "mysql-server mysql-server/root_password password $DBPASSWD"
debconf-set-selections <<< "mysql-server mysql-server/root_password_again password $DBPASSWD"
apt-get install -y mysql-server
mysql -uroot -p$DBPASSWD -e "CREATE DATABASE $DBNAME"
mysql -uroot -p$DBPASSWD -e "CREATE USER '$DBUSER'#'localhost' IDENTIFIED BY '$DBPASSWD'"
mysql -uroot -p$DBPASSWD -e "GRANT ALL PRIVILEGES ON $DBNAME.* TO '$DBUSER'#'localhost'"
mysql -uroot -p$DBPASSWD -e "CREATE USER '$DBUSER'#'10.0.2.2' IDENTIFIED BY '$DBPASSWD'"
mysql -uroot -p$DBPASSWD -e "GRANT ALL PRIVILEGES ON $DBNAME.* TO '$DBUSER'#'10.0.2.2'"
echo "Installed MySQL"
Thanks for any help you can provide.
You should be able to achieve this using sed command from your script
apt-get install -y mysql-server
sed -i "s/.*bind-address.*/bind-address = 0.0.0.0/" /etc/mysql/my.cnf
...
Note you might need to restart the service to take effect if you provision and do not restart the instance for the 1st use, add this then to your script
service mysql stop
service mysql start

Im use terraform to create infrastr. in AWS. I'm using script on ec2 userdata, that connects to rds.But this script doesn`t work.
#! /bin/bash
yum update -y
yum install -y httpd
service httpd start
usermod -a -G apache centos
chown -R centos:apache /var/www
yum install -y mysql php php-mysql
systemctl enable httpd.service
cd /var/www/html/
echo "[mysql]" > ~/.my.cnf
echo "user = myuser" >> ~/.my.cnf
echo "password = passworddata" >> ~/.my.cnf
chmod 600 ~/.my.cnf
cd database/
mysql -h db_server_address < script.sql
systemctl restart httpd.service
/var/log/cloud-init-output.log
ERROR 1045 (28000): Access denied for user 'root'#'10.0.1.91' (using password: NO)
Application cannot connect to the database because there is no schema created.
But, when I do it manually into the instance everything works fine.I understand that script is not perfect, but what's the problem,why the script don`t take credentials from ~/.my.cnf?
Probably env variables are not loaded to load data from /root, use:
mysql --defaults-file=~/.my.cnf -h db_server_address < script.sql
I am trying to install WordPress on my EC2 Linux2.
I use a bash script with even the following rows that I think does not work:
# MySQL
sudo yum install -y mysql
sudo export MYSQL_HOST=${db_address}
sudo mysql --user=${db_username} --password=${db_password} ${db_name}
sudo mysql -e "CREATE USER 'wordpress' IDENTIFIED BY '${db_password}';"
sudo mysql -e "GRANT ALL PRIVILEGES ON ${db_name}.* TO wordpress;"
sudo mysql -e "FLUSH PRIVILEGES;"
sudo mysql -e "Exit"
What is wrong?
I am trying to install mysql in docker and setting default password of root as root using following Dockerfile.
Dockerfile:
FROM ubuntu:20.04
COPY mysql_setup.sh /software/mysql_setup.sh
RUN sh /software/mysql_setup.sh
CMD ["/bin/sh"]
Where /software/mysql_setup.sh
# Download and Install the Latest Updates for the OS
apt-get update && apt-get upgrade -y
# Set the Server Timezone to CST
echo "America/Chicago" > /etc/timezone
dpkg-reconfigure -f noninteractive tzdata

ufw enable
ufw allow 22
ufw allow 3306
# Install essential packages
apt-get -y install zsh htop
# Install MySQL Server in a Non-Interactive mode. Default root password will be "root"
echo "mysql-server mysql-server-8.0.26/root_password password root" | sudo debconf-set-selections
echo "mysql-server mysql-server-8.0.26/root_password_again password root" | sudo debconf-set-selections
apt-get -y install mysql-server
# Run the MySQL Secure Installation wizard
mysql_secure_installation
sed -i 's/127\.0\.0\.1/0\.0\.0\.0/g' /etc/mysql/my.cnf
mysql -uroot -p -e 'USE mysql; UPDATE `user` SET `Host`="%" WHERE `User`="root" AND `Host`="localhost"; DELETE FROM `user` WHERE `Host` != "%" AND `User`="root"; FLUSH PRIVILEGES;'
service mysql restart
But above code does not seem to be working as when i enter into docker and use and use root as password it gives an error.
root#839f2946bfdf:/# mysql -u root -p
Enter password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111)
How can i fix this error?
You cannot run a mysql install inside a container in a normal way. Thing like ufw cannot be done. The entire RUN step is at build time only, so service mysql restart won't be running when the container is started, only CMD is.
Recommend just using the Docker Library mysql container. There's a standard MYSQL_ROOT_PASSWORD variable for setting the root password.
On old MySQL 5.6 I was automatically installing it and creating all needed users and passwords, using the code below.
Is there a way to do the same on a new MySQL 8.0 so that it automatically installs into docker containers allows root without a password and creates all the above?

When I run this docker file of sql it runs.
But when I link it to application using the command
$ docker run --link mysqldb -d abc // here abc is image name of application
& mysqldb is name of sql db image.
it terminates the server and shows cannot open the connection.
Even though I had provided privileges to it and also provided the ip addr of sql image to application image.
I have seen that my sql server is running properly and it connect to mysql client also.
Please proivide a better solution**
