Install with RPM packages

You may install bravos via the copr repository, for Alma/Rocky/Oracle Enterprise Linux and Fedora, simply use:

dnf copr enable mksanthi/noumenia
dnf install bravos

Install with Composer

You may install bravos with composer, to get the latest version use the create-project command, the last dot is important because it tells composer to save the files in the current directory.

composer create-project noumenia/bravos .

How to use

If you installed via the RPM packages then a systemd service is already available and bravos can be started with systemctl. By default, bravos will read the configuration file /etc/bravos.ini and monitor log files defined under the logFiles[] array.

systemctl --now enable bravos

If you installed via composer or manually, then the bravos.ini file will be located in the same directory as the bravos executable and can be specified with the --ini=... parameter. Below is the complete list of command-line parameters:

Usage: bravos [OPTION]...

  -V,  --version             display version information only
  -h,  --help                display help about parameters
  -v,  --verbose             enable verbose output to stdout

  -u,  --user=[USER]         Daemon user
  -g,  --group=[GROUP]       Daemon group

  -l,  --processlimit=[NUM]  Process limit
