Local Install

Instructions for using Vitess on your machine for testing purposes

This guide covers installing Vitess locally for testing purposes, from pre-compiled binaries. We will launch multiple copies of mysqld, so it is recommended to have greater than 4GB RAM, as well as 20GB of available disk space.

A docker setup is also available, which requires no dependencies on your local host.

Install MySQL and etcd #

Vitess supports MySQL 5.6+ and MariaDB 10.0+. We recommend MySQL 5.7 if your installation method provides a choice:

# Ubuntu based
sudo apt install -y mysql-server etcd curl

# Debian
sudo apt install -y default-mysql-server default-mysql-client etcd curl

# Yum based
sudo yum -y localinstall https://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm
sudo yum -y install mysql-community-server etcd curl

On apt-based distributions the services mysqld and etcd will need to be shutdown, since etcd will conflict with the etcd started in the examples, and mysqlctl will start its own copies of mysqld:

# Debian and Ubuntu
sudo service mysql stop
sudo service etcd stop
sudo systemctl disable mysql
sudo systemctl disable etcd

Disable AppArmor or SELinux #

AppArmor/SELinux will not allow Vitess to launch MySQL in any data directory by default. You will need to disable it:


# Debian and Ubuntu
sudo ln -s /etc/apparmor.d/usr.sbin.mysqld /etc/apparmor.d/disable/
sudo apparmor_parser -R /etc/apparmor.d/usr.sbin.mysqld

# The following command should return an empty result:
sudo aa-status | grep mysqld


# CentOS
sudo setenforce 0

Install Vitess #

Download the latest binary release for Vitess on Linux. For example with Vitess 6:

wget https://github.com/vitessio/vitess/releases/download/v${version}/${file}
tar -xzf ${file}
cd ${file/.tar.gz/}
sudo mkdir -p /usr/local/vitess
sudo cp -r * /usr/local/vitess/

Make sure to add /usr/local/vitess/bin to the PATH environment variable. You can do this by adding the following to your $HOME/.bashrc file:

export PATH=/usr/local/vitess/bin:${PATH}

You are now ready to start your first cluster! Open a new terminal window to ensure your .bashrc file changes take effect.

Start a Single Keyspace Cluster #

Start by copying the local examples included with Vitess to your preferred location. For our first example we will deploy a single unsharded keyspace. The file 101_initial_cluster.sh is for example 1 phase 01. Lets execute it now:

cp -r /usr/local/vitess/examples/local ~/my-vitess-example
cd ~/my-vitess-example

You should see output similar to the following:

~/my-vitess-example> ./101_initial_cluster.sh
$ ./101_initial_cluster.sh 
add /vitess/global
add /vitess/zone1
add zone1 CellInfo

You can also verify that the processes have started with pgrep:

~/my-vitess-example> pgrep -fl vtdataroot
14119 etcd
14176 vtctld
14251 mysqld_safe
14720 mysqld
14787 vttablet
14885 mysqld_safe
15352 mysqld
15396 vttablet
15492 mysqld_safe
15959 mysqld
16006 vttablet
16112 vtgate

The exact list of processes will vary. For example, you may not see mysqld_safe listed.

If you encounter any errors, such as ports already in use, you can kill the processes and start over:

pkill -9 -e -f '(vtdataroot|VTDATAROOT)' # kill Vitess processes
rm -rf vtdataroot

Setup Aliases #

For ease-of-use, Vitess provides aliases for mysql and vtctlclient:

source ./env.sh

Setting up aliases changes mysql to always connect to Vitess for your current session. To revert this, type unalias mysql && unalias vtctlclient or close your session.

Connect to your cluster #

You should now be able to connect to the VTGate server that was started in 101_initial_cluster.sh:

~/my-vitess-example> mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2

Summary #

In this example, we deployed a single unsharded keyspace named commerce. Unsharded keyspaces have a single shard named 0. The following schema reflects a common ecommerce scenario that was created by the script:

create table product (
  sku varbinary(128),
  description varbinary(128),
  price bigint,
  primary key(sku)
create table customer (
  customer_id bigint not null auto_increment,
  email varbinary(128),
  primary key(customer_id)
create table corder (
  order_id bigint not null auto_increment,
  customer_id bigint,
  sku varbinary(128),
  price bigint,
  primary key(order_id)

The schema has been simplified to include only those fields that are significant to the example:

  • The product table contains the product information for all of the products.
  • The customer table has a customer_id that has an auto_increment. A typical customer table would have a lot more columns, and sometimes additional detail tables.
  • The corder table (named so because order is an SQL reserved word) has an order_id auto-increment column. It also has foreign keys into customer(customer_id) and product(sku).

Next Steps #

You can now proceed with MoveTables.

Or alternatively, if you would like to teardown your example:

rm -rf vtdataroot
