# estmaster(1)

master process of node servers

## NAME

estmaster - master process of node servers

## SYNOPSIS

**estmaster init \[-ex\] rootdir**

**estmaster start \[-bg\] \[-ro\] \[-st\] rootdir**

**estmaster stop rootdir**

**estmaster unittest rootdir**

**estmaster crypt key \[hash\]**

## 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.
