estmaster: 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.
