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?
RUN yum -y install https://dev.mysql.com/get/mysql57-community-release-el7-11.noarch.rpm
RUN yum-config-manager --disable mysql57-community; yum-config-manager --enable mysql56-community
RUN yum -y install mysql-community-server mysql-community-client
#Configure MySQL
# Needed to create system tables etc.
chown -R mysql:mysql /var/lib/mysql
su -l mysql -c "/usr/bin/mysql-systemd-start pre"
# Start main service
(su -l mysql -c "/usr/bin/mysqld_safe --basedir=/usr") &
# Don't signal startup success before a ping works
su -l mysql -c "/usr/bin/mysql-systemd-start post"
mysql -e "CREATE DATABASE IF NOT EXISTS \`${USERNAME}\`;"
mysql -e "GRANT ALL PRIVILEGES ON \`${USERNAME}\`.* TO \`${USERNAME}\`#'%' IDENTIFIED BY \"${MYSQL_PASS}\";"
mysql -e "GRANT ALL PRIVILEGES ON \`${USERNAME}\`.* TO \`${USERNAME}\`#'localhost' IDENTIFIED BY \"${MYSQL_PASS}\";"

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?
everyone. Ive started to learn bash and DevOps, lost 2 days, but I cant understand the following:
requirments
Centos 7
DB mysql
zabbix server version 4
mariadb
I need to write bash script (script at the end of the question), that creates and runs zabbix server (exactly 4 version). When I run the script manually step by step (inserting each command in pwsh by hand) in two ways for db creating (example1 or example2) - it is executed properly: zabbix db is created, all services started, zabbix frontend is working well.
But when I run the script as root user or as local user by command:
>sh -c /home/zabbix_server
script is finished by:
>Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-server.service to /usr/lib/systemd/system/zabbix-server.service.
>Created symlink from /etc/systemd/system/multi-user.target.wants/zabbix-agent.service to /usr/lib/systemd/system/zabbix-agent.service.
>Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
there are no error messages during or at the end of the script, but when I try manually execute the command create db (example1 or example2), it's doesn't matter:
#Create DB (example1)
mysql -uroot <<EOF
create database zabbix character set utf8 collate utf8_bin;
create user 'zabbix'#'localhost' identified by 'zabbix';
grant all privileges on zabbix.* to 'zabbix'#'localhost';
EOF
#Create DB (example2)
mysql -u root -e "CREATE DATABASE zabbix; CREATE USER zabbix#localhost identified by 'zabbix'; GRANT ALL ON zabbix.* to zabbix#localhost WITH GRANT OPTION;"
I get the error message: ... db can't be created, zabbix base exist
But the result of the command:
>show databases;
doesn't show db zabbix in db list.

#Make Zabbix server and agent processes start at system boot
systemctl enable zabbix-server zabbix-agent httpd
Depending on what you want to achieve, this may be a good suggestion:
CREATE DATABASE IF NOT EXISTS zabbix;
This makes the call idempotent!
The problem was, that the script contains a \r (CR) at the end (0d). Remove it with:
tr -d '\r' < old_name_script > new_name_script
And the script works fine.
If it will be useful, there is fully working example of the script, that creates zabbix server:
#!/usr/bin/env bash
#Disable SELinux
enforceStatus=getenforse
if [ "$enforceStatus" != "Permissive" ]; then
setenforce 0
fi

Does anybody knows how to install mysql-server via dockerfile? I have written a Dockerfile, but the build ends with an error: /bin/sh: 1: /usr/bin/mysqld: not found

For an ubuntu:16.04 base image, mysqld is found in /usr/sbin, not /usr/bin
If you can add a step RUN which mysqld before your final RUN command that will show you where the mysqld executable is found. It may vary depending on which base image/distro you're using.
You can also use RUN mysqld ... without a full path, if the file is in your $PATH
You may also need to update your RUN sed line as below, adding spaces around the quoted string:
RUN sed -i -e "s/^bind-address\s*=\s*127.0.0.1/bind-address = 0.0.0.0/" /etc/mysql/my.cnf
Otherwise, you may see the following error:
The command '/bin/sh -c sed -i -e"s/^bind-address\s*=\s*127.0.0.1/bind-address = 0.0.0.0/"/etc/mysql/my.cnf' returned a non-zero code: 1
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
I want to have a mysql database with some basic dataset.
I create mysql docker image using this https://index.docker.io/u/brice/mysql/ Dockerfile, but delete VOLUME ["/var/lib/mysql", "/var/log/mysql"] line, so the Dockerfile looks like:
FROM ubuntu:12.10
MAINTAINER Brandon Rice <brice84#gmail.com>
RUN dpkg-divert --local --rename --add /sbin/initctl
RUN ln -s /bin/true /sbin/initctl
RUN apt-get update
RUN apt-get upgrade -y
RUN apt-get -y install mysql-server
RUN sed -i -e"s/^bind-address\s*=\s*127.0.0.1/bind-address = 0.0.0.0/" /etc/mysql/my.cnf
RUN /usr/bin/mysqld_safe & \
sleep 10s && \
mysql < create_my_db.sql && \
mysql -e "GRANT ALL ON *.* to 'root'#'%'; FLUSH PRIVILEGES"
EXPOSE 3306
CMD ["mysqld_safe"]
After that I build image such as:
docker build -t my_db_mysql .
Everything is ok while i append data, but when i want to delete db, for example:
FROM my_db_mysql
RUN /usr/bin/mysqld_safe & \
sleep 10s && \
mysql -e "DROP DATABASE my_db;"
EXPOSE 3306
CMD ["mysqld_safe"]
I obtain next error:
ERROR 6 (HY000) at line 1: Error on delete of './my_db//db.opt' (Errcode: 1)
It is appears not only when I want to build image, but even when I exec: mysql -u user -p -e "DROP DATABASE my_db;"
How to solve this?
Thanks
Update: Also I tried to run docker with different filesystem, e.g -s vfs or -s devicemapper, but nothing changed.
When I build image with VOLUME ["/var/lib/mysql", "/var/log/mysql"] - everything works properly, but i can't commit this changes.
Update: Seems I resolve this issue. Problem was in host machine with ubuntu 12.04. Issue disappeared when I update ubuntu to 13.10. Thank a lot!
