My java app can automatically generate table and connect database when I run my java application since I already configure the username and password of mysql into java application codes. But in terms of installing mysql in EC2 using packer, it will have a temporary password, my java application could not connect mysql? In this case, what can I do, should I use docker to avoid this issue? I will highly appreciated any help.
I always have a error, when I run java application in EC2 due to temporary password issue
ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: YES)

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
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?

I was forced to reinstall macOS Sierra because I was in the beta program for High Sierra and I get a serious crash so I downgraded the system.
This Dockerfile was working in High Sierra before the sudden crash of the system.

Now, reinstalling all things I does not work, it always outputs the same error:
Starting MySQL database server mysqld
...fail!
To add some information, in the step where the Dockerfile stops I am starting the service to dump a database.
My system version macOS Sierra 10.12.6 (16G29) is and my Docker version is 17.06.0-ce-mac19 (18663). Any workaround for this problem?
You should be using the official MySQL Dockerfile as your starting point. You could either just use the MySQL image itself, FROM mysql:5.7 for your Dockerfile or you can copy the Dockerfile and the docker-entrypoint,sh from their Github to "take control" of the MySQL image and not have any dependency on MySQL releases/changes.
I think it is a good idea to use the same OS base for all your Docker containers, you are currently using Ubuntu distro, if you do not mind or are just getting started you may want to have Debian be your OS base. I say this because the Docker images I have looked so far, Cloudbee's Jenkins, .NET Core, ASP.NET COre and MySQL all have a Debian base so I been thinking Debian is the most popular OS base for Docker images though I only have anecdotal evidence of this obviously.
My company prefers CentOS distro, so I took the official MySQL Dockerfile and converted to work with CentOS:7, it was a pain.
I am trying to create a bash shell script to automate the installation of MySQL Community Server version 5.7 on CentOS 7 (x64).
I came across this lovely script https://github.com/mysql/mysql-docker/blob/mysql-server/5.7/docker-entrypoint.sh and put together the following:
#!/bin/sh
DATADIR="/var/lib/mysql"
MYSQL_ROOT_PASSWORD="$(pwmake 128)"
echo ' -> Removing previous mysql installation';
systemctl stop mysqld.service && yum remove -y mysql-community-server && rm -rf /var/lib/mysql && rm -rf /var/log/mysqld.log
echo ' -> Installing mysql database server';
yum localinstall -y https://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm
yum install -y mysql-community-server
echo ' -> Creating mysql data directory'
mkdir -p "$DATADIR"
chown -R mysql:mysql "$DATADIR"
echo ' -> Initializing mysql database'
mysqld --initialize-insecure=on --user=mysql --datadir="$DATADIR"
mysqld --user=mysql --datadir="$DATADIR" --skip-networking & pid="$!"
mysql=( mysql --protocol=socket -uroot )
for i in {30..0}; do
if echo 'SELECT 1' | "${mysql[#]}" &> /dev/null; then
break
fi
echo 'MySQL init process in progress ...'
sleep 1
done
if [ "$i" = 0 ]; then
echo >&2 'MySQL init process failed'
exit 1
fi
echo ' -> Setting mysql server root password';
mysql_tzinfo_to_sql /usr/share/zoneinfo | "${mysql[#]}" mysql
"${mysql[#]}" <<-EOSQL
SET ##SESSION.SQL_LOG_BIN=0;
DELETE FROM mysql.user where user != 'mysql.sys';
CREATE USER 'root'#'%' IDENTIFIED BY '${MYSQL_ROOT_PASSWORD}' ;
GRANT ALL ON *.* TO 'root'#'%' WITH GRANT OPTION ;
DROP DATABASE IF EXISTS test ;
FLUSH PRIVILEGES ;
EOSQL
if [ ! -z "$MYSQL_ROOT_PASSWORD" ]; then
mysql+=( -p"${MYSQL_ROOT_PASSWORD}" )
fi
if ! kill -s TERM "$pid" || ! wait "$pid"; then
echo >&2 'MySQL init process failed.'
exit 1
fi
chown -R mysql:mysql "$DATADIR"
echo " -> Mysql server setup completed, your root password: $MYSQL_ROOT_PASSWORD"
The script is supposed to do the following:
Removing previous mysql installation
Installing mysql database server
Creating mysql data directory & set ownership
Initializing mysql database
Setting mysql server root password
When I ran the script, this is the output I've got:
Total download size: 142 M
Installed size: 652 M

I thought the steps in the script were pretty straight forward, yet it failed. Any ideas why it might be?
I have managed to achieve this by re-writing the shell script. This now works flawlessly for me :)

I have been downloaded the DEB package of mysql 5.5.23.
Install MySQL by the command as follows:
sudo dpkg -i mysql-5.5.23-debian6.0-x86_64.deb
The result said that installed successfully.
But when I type the command:
sudo service mysql start
Or
mysql
It shows me that "mysql: unrecognized service" or "mysql: command not found".
Besides, I can't find MySQL files in "/usr/include" or "/usr/bin"
Please help me. Thx.
Because MySQL 5.5.x is not packaged, in repositories only exist 5.1.x
This worked for me:
http://www.rebojo.com/debian-installing-mysql/
Why not a simple command :
sudo apt-get install mysql-server
MySQL Download URL
https://dev.mysql.com/get/Downloads/MySQL-5.5/mysql-5.5.56-linux-glibc2.5-x86_64.tar.gz
Open the terminal and follow along:
Uninstall any existing version of MySQL
sudo rm /var/lib/mysql/ -R
Delete the MySQL profile
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
Add mysql user group
sudo groupadd mysql
Add mysql (not the current user) to mysql user group
sudo useradd -g mysql mysql
Extract it
sudo tar -xvf mysql-5.5.56-linux-glibc2.5-x86_64.tar.gz
Move it to /usr/local
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-5.5.49-linux2.6-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
Start mysql
sudo bin/mysqld_safe --user=mysql &
sudo cp support-files/mysql.server /etc/init.d/mysql.server
Set root user password
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
Stop mysql server
sudo /etc/init.d/mysql.server stop
Check status of mysql
sudo /etc/init.d/mysql.server status
Enable myql on startup
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
