I created a basic vagrant box based on ubuntu/trusty64.
When i "vagrant up" the machine and next "vagrant ssh" into it, everything is fine.
Next step would be to install latest mysql 5.7, so thats what i did:
wget http://dev.mysql.com/get/mysql-apt-config_0.7.3-1_all.deb
sudo dpkg -i mysql-apt-config_0.7.3-1_all.deb
sudo apt-get update
sudo apt-get install -y mysql-server
So it downloads configures etc... next an "interactive" shell appears, where are i am requested to type password and repeat.
MySql 5.7 is installed successfully in my machine...BUT:
I would like it to be installed during "vagrant up", thats why i modified Vagrantfile with:
config.vm.provision :shell, path: "bootstrap.sh"
In bootstrap.sh i added content:
wget http://dev.mysql.com/get/mysql-apt-config_0.7.3-1_all.deb
sudo dpkg -i mysql-apt-config_0.7.3-1_all.deb
sudo apt-get update
sudo apt-get install -y mysql-server
This fails completely... in console i can read it tries to configure mysql 5.5 and its dependencies.
But why?
If anybody could help with this issue, i would be really thankful.
Thanks and Greetings!

The SSH command responded with a non-zero exit status. Vagrant
assumes that this means the command failed. The output for this command
should be in the log above. Please read the output to determine what
went wrong.
The reason why vagrant is installing 5.5 instead of 5.7 is because ubuntu/trusty version might be ubuntu 14.04, default mysql version for ubuntu 14.04 is mysql 5.5.
Below is a vagrant file which automatically installs mysql 5.7, but I have configured centos6 here. Feel free to change the os and set that to ubuntu/trusty. Just do
mysql57_config.vm.box = 'ubuntu/trusty64'
Instructions:
mkdir mysql-5-7
cd mysql-5-7
Once you are in mysql-5-7 directory add these two files, Vagrantfile and bootstrap.sh file

Ones you are in the machine connected to mysql: connect to mysql and provide below credentials~~

Somewhere in /etc/sudoers (or /etc/sudoers.d if it's included) you have to have

without that, the vagrant ssh (without tty) fails mysteriously.
If you are using MacOS, turn Off firewall and see it this works?
I have mariadb in my ubuntu system but it is not working properly , so i want to again install mysql in my system .
For Remove mariadb i have run these commands .
sudo apt-get --purge remove "mysql*"
sudo mv /etc/mysql/ /tmp/mysql_configs/
nano /etc/apt/sources.list
sudo apt-get update
sudo apt-get install mysql-server-5.6
but after step 5 it's give me these errors :

You might want to run 'apt-get -f install' to correct these:

Can anyone give me suggestion how can i install mysql in my system . Thanks in advance .
First of all, you need to update the system.
sudo apt update && upgrade
then perform the MySQL installation commands and follow the instructions.
sudo apt install mysql-server
sudo mysql_secure_installation
Once it has done. try to open MySQL.
sudo mysql
try to check the authentication method each of your MySQL user accounts uses with the following command in the MySQL terminal:
SELECT user,authentication_string,plugin,host FROM mysql.user;
this will return users with authentication_string.
Change the MySQL root password with the following command.
ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'password';
FLUSH PRIVILEGES;
Flush Privileges which tells the server to reload the grant tables and put your new changes into effect
It's very simple to install mysql on ubuntu , just follow these steps :
Step 1 : update the system
sudo apt update
Step 2 : Install mysql package
sudo apt install mysql-server
Step 3 : Once the installation is completed, the MySQL service will start automatically. To check whether the MySQL server is running, type:
sudo systemctl status mysql
The output of the following command should be :
OUTPUT
mysql.service - MySQL Community Server
Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset: enabled)
Active: active (running) since Wed 2018-06-20 11:30:23 PDT; 5min ago
Main PID: 17382 (mysqld)
Tasks: 27 (limit: 2321)
CGroup: /system.slice/mysql.service
`-17382 /usr/sbin/mysqld --daemonize --pid-file=/run/mysqld/mysqld.pid
Step 4 : Securing MySQL
sudo mysql_secure_installation
select one of the three levels of password validation policy(strong recommended).Set your password ,and then type y(yes) to all the questions , this will improve the security .
Step 5 : Once it has done. open MySQL by typing the following command :
sudo mysql
Step 6 : If you want to login to your MySQL server as root from an external program such as phpMyAdmin , then type these commands inside mysql.
mysql>ALTER USER 'root'#'localhost' IDENTIFIED WITH mysql_native_password BY 'strong_password';
mysql>FLUSH PRIVILEGES;
mysql>exit;
After this you will be successfully able to run mysql , for this open terminal and type.
mysql -u root -p
Now type your password.
Congo! you are done with installing mysql.
Lesson from continuous deployment test. You MUST do this purge mysql-common. You CANNOT put mariadb and mysql in the same system, they want their own mysql-common and not sharing them. Which many other API wrapped around it to connect to those server.
And you must comment all the repo pointing to mariadb. Otherwise it will install the same version again from mariadb.
sudo apt-get purge mysql-common
# Put back the mysql-common , make sure you use the new mysql repo,
# remarks mariadb repo
sudo apt-get install software-properties-common
Always check whether any OTHER file or folder contains mariadb repo.
cd /etc/apt
fgrep -lR "maria"
The easy way for this is installing the synaptic package manager by typing the following command in the terminal:
sudo apt-get install synaptic
And then open synaptic by:
sudo synaptic
Then search for the package you have installed, mariadb, and mark it for complete removal and press apply.
And these commands to install mysql-server
sudo apt-get update
sudo apt-get install mysql-server
It's quite easy to install mysql on Ubuntu.
sudo apt-get update
sudo apt-get install mysql-server
You'll be asked to create a new password for root user. Set a good password and you're ready to go.
You can also follow this youtube videos for installation and basic understanding for Mysql
sudo apt-get update
sudo apt-get install mysql-server -y
if setup password
sudo mysql_secure_installation
if set new user
sudo mysql
>CREATE USER 'username'#'%' IDENTIFIED BY 'password';
>FLUSH PRIVILEGES;
>exit
sudo systemctl restart mysql
Ubuntu 14.04 installation, with nginx, passenger and postgresql. The following steps are run:
sudo apt-get update && sudo apt-get upgrade -y
sudo apt-get install mysql-server
sudo mysql_secure_installation _for allowing only localhost connection_
sudo apt-get install sphinxsearch
gem file has
gem 'mysql2', '0.3.18', :platform => :ruby
gem 'thinking-sphinx', '3.1.4'
thinking_sphinx.yml specifies
mysql41: 9312
Running:
RAILS_ENV=development bundle exec rake ts:rebuild
proceeds correctly: total 112 writes, 0.079 sec, 485.0 kb/call avg, 0.7 msec/call avg Started searchd successfully (pid: 21644).
netstat -ltnp shows only one searchd process
tcp 0 0 127.0.0.1:9312 0.0.0.0:* LISTEN 21644/searchd
So one concludes that everything is a go... right? [nasty buzzer]
ThinkingSphinx::ConnectionError
Error connecting to Sphinx via the MySQL protocol.
Error connecting to Sphinx via the MySQL protocol. _nice... stated twice!_
Can't connect to MySQL server on '127.0.0.1' (111)
Possible avenues for non-connection:
mySql-server root password not digested
nginx somehow impeding the connection
others? how to verify/assert?
While Sphinx implements the MySQL protocol for querying, it does not pay any attention to authentication, so Thinking Sphinx doesn't use those fields either. So I'm not sure if mysql_secure_installation is the right tool for the job - certainly, not if it's trying to use authentication to control access. If you don't want to allow external communication to Sphinx, can you just block the port?
Building on Pat's observation the following got me running on Ubuntu 14.04 installation, with nginx, passenger and postgresql.
sudo apt-get update && sudo apt-get upgrade -y
sudo apt-get install mysql-server
sudo apt-get install sphinx search
Ensure gem file has
gem 'mysql2', '0.3.18', :platform => :ruby
gem 'thinking-sphinx', '3.1.4'
# alternately with JRuby
gem 'jdbc-mysql', '~> 5.1.28', :platform => :jruby
thinking_sphinx.yml must specify
mysql41: [port_number]
multiple search processes need distinct ports.
Configure, index and start via:
RAILS_ENV=[your_environment] bundle exec rake ts:rebuild
sudo netstat -ltnp should show the listen port as defined in thinking_sphinx.yml and rendered in config/[your_environment].sphinx.conf
tcp 0 0 127.0.0.1:[port_number] 0.0.0.0:* LISTEN 21644/searchd
Finally,
sudo reboot
