/** This tool can be used to install ClickHouse without a deb/rpm/tgz package, having only "clickhouse" binary.
|
|
* It also allows to avoid dependency on systemd, upstart, SysV init.
|
|
*
|
|
* The following steps are performed:
|
|
*
|
|
* - copying the binary to binary directory (/usr/bin).
|
|
* - creation of symlinks for tools.
|
|
* - creation of clickhouse user and group.
|
|
* - creation of config directory (/etc/clickhouse-server).
|
|
* - creation of default configuration files.
|
|
* - creation of a directory for logs (/var/log/clickhouse-server).
|
|
* - creation of a data directory if not exists.
|
|
* - setting a password for default user.
|
|
* - choose an option to listen connections.
|
|
* - changing the ownership and mode of the directories.
|
|
* - setting capabilities for binary.
|
|
* - setting ulimits for the user.
|
|
* - (todo) put service in cron.
|
|
*
|
|
* It does not install clickhouse-odbc-bridge.
