DESCRIPTION


estmaster is an aggregation of sub commands. The name of a sub command is specified by
the first argument. Other arguments are parsed according to each sub command. The
argument rootdir specifies the server root directory which contains configuration file and
so on.

estmaster init [-ex] rootdir
Create the server root directory.
If -ex is specified, some users and some nodes are set for example. By default,
only a super user whose name and password are both "admin" is set.

estmaster start [-bg] [-ro] [-st] rootdir
Start the node master.
If -bg is specified, the server runs in background as a daemon process.
If -ro is specified, the server runs in read-only mode regardless of the
configuration.
If -st is specified, the server runs in single thread mode.

estmaster stop rootdir
Stop the running node master.

estmaster unittest rootdir
Perform unit tests.

estmaster crypt key [hash]
Output an encrypted string of a string.
key specifies a target string.
If hash is specified, it checks whether the key and the hash matches.

All sub commands return 0 if the operation is success, else return 1. A running node
master finishes with closing the database when it catches the signal 1 (SIGHUP), 2
(SIGINT), 3 (SIGQUIT), or 15 (SIGTERM). Moreover, when a node master running as a daemon
catches the signal 1 (SIGHUP), the process is re-start and re-read the configuration
files.

A running node server should be finished by valid means by command line or via network.
Otherwise, the index may be broken.
