As user root, download the latest version of the scripts collection (see Releases page):
# wget https://github.com/Azmodey/ch_dba_scripts/archive/1.3.0.tar.gz
Extract script files to separate directory (for example ~scripts/) and grant the necessary execution rights:
# tar xvzf 1.3.0.tar.gz
# mv ch_dba_scripts-1.3.0/scripts ~/scripts
# chmod 700 ~/scripts/*.sh
# chmod 600 ~/scripts/settings.txt
Modify file settings.txt. Uncomment and correct the entries for your current ClickHouse connection settings.
CH_HOST="localhost" # Host name. Default: localhost
CH_PORT="9000" # Port. Default: 9000
CH_LOGIN="" # Administrative user login
CH_PASSWORD="" # Administrative user password
If you plan to use Apache ZooKeeper cluster health monitoring, you should add this feature to the configuration file. Add the following lines to your ZooKeeper config file like /opt/zookeeper/conf/zoo.cfg :
# Whitelist for statistics
4lw.commands.whitelist=stat, mntr
