DBdeployer is a tool that deploys MySQL database servers easily.
With dbdeployer, you can deploy a single sandbox, or many sandboxes at once, with or without replication.
The main commands are single, replication, and multiple, which work with MySQL tarball that have been unpacked into the sandbox-binary directory (by default, $HOME/opt/mysql.)
To use a tarball, you must first run the unpack command, which will unpack the tarball into the right directory.
For example:
$ dbdeployer --unpack-version=8.0.4 unpack mysql-8.0.4-rc-linux-glibc2.12-x86_64.tar.gz
Unpacking tarball mysql-8.0.4-rc-linux-glibc2.12-x86_64.tar.gz to $HOME/opt/mysql/8.0.4
.........100.........200.........292
$ dbdeployer single 8.0.4
Database installed in $HOME/sandboxes/msb_8_0_4
. sandbox server started
The program doesn't have any dependencies. Everything is included in the binary. Calling dbdeployer without arguments or with '--help' will show the main help screen.
$ dbdeployer -h
Makes MySQL server installation an easy task.
Runs single, multiple, and replicated sandboxes.
Usage:
dbdeployer [command]
Available Commands:
delete delete an installed sandbox
help Help about any command
multiple create multiple sandbox
replication create replication sandbox
sandboxes List installed sandboxes
single deploys a single sandbox
unpack unpack a tarball into the binary directory

--version version for dbdeployer
Use "dbdeployer [command] --help" for more information about a command.
The flags listed in the main screen can be used with any commands. The flags --my-cnf-options and --init-options can be used several times.
If you don't have any tarballs installed in your system, you should first unpack it (see an example above).
$ dbdeployer unpack -h
If you want to create a sandbox from a tarball, you first need to unpack it
into the sandbox-binary directory. This command carries out that task, so that afterwards
you can call 'single', 'multiple', and 'replication' commands with only the MySQL version
for that tarball.
Usage:
dbdeployer unpack MySQL-tarball [flags]
Examples:
$ dbdeployer --unpack-version=8.0.4 unpack mysql-8.0.4-rc-linux-glibc2.12-x86_64.tar.gz
Unpacking tarball mysql-8.0.4-rc-linux-glibc2.12-x86_64.tar.gz to $HOME/opt/mysql/8.0.4
.........100.........200.........292
Flags:
-h, --help help for unpack
--prefix string Prefix for the final expanded directory
--unpack-version string which version is contained in the tarball (mandatory)
Global Flags:
--bind-address string defines the database bind-address (default "127.0.0.1")

--rpl-user string replication user (default "rsandbox")
--sandbox-binary string Binary repository (default "$HOME/opt/mysql")
--sandbox-home string Sandbox deployment direcory (default "$HOME/sandboxes")
The main command is single, which installs a single sandbox.
$ dbdeployer single -h
single installs a sandbox and creates useful scripts for its use.
MySQL-Version is in the format x.x.xx, and it refers to a directory named after the version
containing an unpacked tarball. The place where these directories are found is defined by
--sandbox-binary (default: $HOME/opt/mysql.)
For example:
dbdeployer single 5.7.21
For this command to work, there must be a directory $HOME/opt/mysql/5.7.21, containing
the binary files from mysql-5.7.21-$YOUR_OS-x86_64.tar.gz
Use the "unpack" command to get the tarball into the right directory.
Usage:
dbdeployer single MySQL-Version [flags]
Flags:
-h, --help help for single
--master Make the server replication ready
Global Flags:
--bind-address string defines the database bind-address (default "127.0.0.1")
--config string config file (default "./dbdeployer.json")
-p, --db-password string database password (default "msandbox")
-u, --db-user string database user (default "msandbox")
--gtid enables GTID

-c, --my-cnf-options strings mysqld options to add to my.sandbox.cnf

--rpl-user string replication user (default "rsandbox")
--sandbox-binary string Binary repository (default "$HOME/opt/mysql")
--sandbox-home string Sandbox deployment direcory (default "$HOME/sandboxes")
If you want more than one sandbox of the same version, without any replication relationship, use the multiple command with an optional "--node" flag (default: 3).
$ dbdeployer multiple -h
create multiple sandbox

The replication command will install a master and two or more slaves, with replication started. You can change the topology to "group" and get three nodes in peer replication.
$ dbdeployer replication -h
The replication command allows you to deploy several nodes in replication.
Allowed topologies are "master-slave" and "group" (requires 5.7.17+)
Usage:
dbdeployer replication MySQL-Version [flags]
Examples:
$ dbdeployer replication 5.7.21
# (implies topology = master-slave)
$ dbdeployer --topology=master-slave replication 5.7.21
# (explicitly setting topology)
$ dbdeployer --topology=group replication 5.7.21
Flags:
-h, --help help for replication
-n, --nodes int How many nodes will be installed (default 3)
-t, --topology string Which topology will be installed (default "master-slave")
Global Flags:
--bind-address string defines the database bind-address (default "127.0.0.1")
--config string config file (default "./dbdeployer.json")
-p, --db-password string database password (default "msandbox")
-u, --db-user string database user (default "msandbox")

-i, --init-options strings mysqld options to run during initialization
--keep-auth-plugin in 8.0.4+, does not change the auth plugin

--rpl-user string replication user (default "rsandbox")
--sandbox-binary string Binary repository (default "$HOME/opt/mysql")
--sandbox-home string Sandbox deployment direcory (default "$HOME/sandboxes")
You can list the available MySQL versions with
$ dbdeployer versions
Also "available" is a recognized alias for this command.
And you can list which sandboxes were already installed
$ dbdeployer installed
The command "usage" shows how to use the scripts that were installed with each sandbox.
$ dbdeployer usage
USING A SANDBOX
Change directory to the newly created one (default: $SANDBOX_HOME/msb_VERSION
for single sandboxes)
[ $SANDBOX_HOME = $HOME/sandboxes unless modified with flag --sandbox-home ]
The sandbox directory of the instance you just created contains some handy
scripts to manage your server easily and in isolation.
"./start", "./status", "./restart", and "./stop" do what their name suggests.
start and restart accept parameters that are eventually passed to the server.
e.g.:
./start --server-id=1001
./restart --event-scheduler=disabled
"./use" calls the command line client with the appropriate parameters,
Example:
./use -BN -e "select @@server_id"
./use -u root
"./clear" stops the server and removes everything from the data directory,
letting you ready to start from scratch. (Warning! It's irreversible!)
USING MULTIPLE SERVER SANDBOX
On a replication sandbox, you have the same commands (run "dbdeployer usage single"),
with an "_all" suffix, meaning that you propagate the command to all the members.
Then you have "./m" as a shortcut to use the master, "./s1" and "./s2" to access
the slaves (and "s3", "s4" ... if you define more).
In group sandboxes without a master slave relationship (group replication and
multiple sandboxes) the nodes can be accessed by ./n1, ./n2, ./n3, and so on.
start_all
status_all
restart_all
stop_all
use_all
clear_all
m
s1, s2, n1, n2
The scripts "check_slaves" or "check_nodes" give the status of replication in the sandbox.
