Local Install via Homebrew

Instructions for using Vitess on your macOS machine for testing purposes

This guide covers installing Vitess locally to macOS 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 Homebrew package manager is also available, which requires no dependencies on your local host.

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Install Vitess with Homebrew #

+-------+----------+-------+------------+---------+------------------+-----------+----------------------+

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

$ pgrep -fl vitess | awk '{print $2,$3}'
etcd --enable-v2=true
vtctld -topo_implementation
/bin/sh /usr/local/opt/mysql@5.7/bin/mysqld_safe
/usr/local/opt/mysql@5.7/bin/mysqld --defaults-file=/usr/local/Cellar/vitess/9.0.0/share/vitess/examples/local/vtdataroot/vt_0000000100/my.cnf
vttablet -topo_implementation
/bin/sh /usr/local/opt/mysql@5.7/bin/mysqld_safe
/usr/local/opt/mysql@5.7/bin/mysqld --defaults-file=/usr/local/Cellar/vitess/9.0.0/share/vitess/examples/local/vtdataroot/vt_0000000101/my.cnf
vttablet -topo_implementation
/bin/sh /usr/local/opt/mysql@5.7/bin/mysqld_safe
/usr/local/opt/mysql@5.7/bin/mysqld --defaults-file=/usr/local/Cellar/vitess/9.0.0/share/vitess/examples/local/vtdataroot/vt_0000000102/my.cnf
vttablet -topo_implementation
vtgate -topo_implementation
vtorc --topo_implementation

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 -f '(vtdataroot|VTDATAROOT|vitess|vtadmin)' # kill Vitess processes
rm -rf /usr/local/Cellar/vitess/15.0.0/share/vitess/examples/local/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:

/usr/local/share/vitess/examples/local> mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2

VTOrc is also setup as part of the initialization. You can look at its user-interface at:

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:

pkill -9 -f '(vtdataroot|VTDATAROOT)' # kill Vitess processes
rm -rf /usr/local/Cellar/vitess/9.0.0/share/vitess/examples/local/vtdataroot
