# Installing MariaDB MaxScale using a tarball
|
|
|
|
MariaDB MaxScale is also made available as a tarball, which is named like
|
|
`maxscale-x.y.z.OS.tar.gz` where `x.y.z` is the same as the corresponding version and `OS`
|
|
identifies the operating system, e.g. `maxscale-2.0.1.centos.7.tar.gz`.
|
|
|
|
In order to use the tarball, the following libraries are required:
|
|
|
|
- libcurl
|
|
- libaio
|
|
- OpenSSL
|
|
|
|
The tarball has been built with the assumption that it will be installed in `/usr/local`.
|
|
However, it is possible to install it in any directory, but in that case MariaDB MaxScale
|
|
must be invoked with a flag.
|
|
|
|
## Installing as root in `/usr/local`
|
|
|
|
If you have root access to the system you probably want to install MariaDB MaxScale under
|
|
the user and group `maxscale`.
|
|
|
|
The required steps are as follows:
|
|
|
|
$ sudo groupadd maxscale
|
|
$ sudo useradd -g maxscale maxscale
|
|
$ cd /usr/local
|
|
$ sudo tar -xzvf maxscale-x.y.z.OS.tar.gz
|
|
$ sudo ln -s maxscale-x.y.z.OS maxscale
|
|
$ cd maxscale
|
|
$ sudo chown -R maxscale var
|
|
|
|
Creating the symbolic link is necessary, since MariaDB MaxScale has been built
|
|
with the assumption that the plugin directory is `/usr/local/maxscale/lib/maxscale`.
|
|
|
|
The symbolic link also makes it easy to switch between different versions of
|
|
MariaDB MaxScale that have been installed side by side in `/usr/local`;
|
|
just make the symbolic link point to another installation.
|
|
|
|
In addition, the first time you install MariaDB MaxScale from a tarball
|
|
you need to create the following directories:
|
|
|
|
$ sudo mkdir /var/log/maxscale
|
|
$ sudo mkdir /var/lib/maxscale
|
|
$ sudo mkdir /var/run/maxscale
|
|
$ sudo mkdir /var/cache/maxscale
|
|
|
|
and make `maxscale` the owner of them:
|
|
|
|
$ sudo chown maxscale /var/log/maxscale
|
|
$ sudo chown maxscale /var/lib/maxscale
|
|
$ sudo chown maxscale /var/run/maxscale
|
|
$ sudo chown maxscale /var/cache/maxscale
|
|
|
|
The following step is to create the MariaDB MaxScale configuration file `/etc/maxscale.cnf`.
|
|
The file `etc/maxscale.cnf.template` can be used as a base.
|
|
Please refer to [Configuration Guide](Configuration-Guide.md) for details.
|
|
|
|
When the configuration file has been created, MariaDB MaxScale can be started.
|
|
|
|
$ sudo bin/maxscale --user=maxscale -d
|
|
|
|
The `-d` flag causes maxscale _not_ to turn itself into a daemon,
|
|
which is adviseable the first time MariaDB MaxScale is started, as it makes it easier to spot problems.
|
|
|
|
If you want to place the configuration file somewhere else but in `/etc`
|
|
you can invoke MariaDB MaxScale with the `--config` flag,
|
|
for instance, `--config=/usr/local/maxscale/etc/maxscale.cnf`.
|
|
|
|
Note also that if you want to keep _everything_ under `/usr/local/maxscale`
|
|
you can invoke MariaDB MaxScale using the flag `--basedir`.
|
|
|
|
$ sudo bin/maxscale --user=maxscale --basedir=/usr/local/maxscale -d
|
|
|
|
That will cause MariaDB MaxScale to look for its configuration file in
|
|
`/usr/local/maxscale/etc` and to store all runtime files under `/usr/local/maxscale/var`.
|
|
|
|
## Installing in any Directory
|
|
|
|
Enter a directory where you have the right to create a subdirectory. Then do as follows.
|
|
|
|
$ tar -xzvf maxscale-x.y.z.OS.tar.gz
|
|
|
|
The next step is to create the MaxScale configuration file `maxscale-x.y.z/etc/maxscale.cnf`.
|
|
The file `maxscale-x.y.z/etc/maxscale.cnf.template` can be used as a base.
|
|
Please refer to [Configuration Guide](Configuration-Guide.md) for details.
|
|
|
|
When the configuration file has been created, MariaDB MaxScale can be started.
|
|
|
|
$ cd maxscale-x.y.z.OS
|
|
$ bin/maxscale -d --basedir=.
|
|
|
|
With the flag `--basedir`, MariaDB MaxScale is told where the `lib`, `etc` and `var`
|
|
directories are found. Unless it is specified, MariaDB MaxScale assumes
|
|
the `lib` directory is found in `/usr/local/maxscale`,
|
|
and the `var` and `etc` directories in `/`.
|
|
|
|
It is also possible to specify the directories and the location of
|
|
the configuration file individually. Invoke MaxScale like
|
|
|
|
$ bin/maxscale --help
|
|
|
|
to find out the appropriate flags.
