They can be edited with a plain text editor, such as +vi, emacs or your favourite IDE (Xcode) + +It is assumed you are comfortable with installing software from the +terminal command line and know how to use sudo to acquire root access. + +If you are not familiar with the macOS command line then +please consider using ChronyControl from http://whatroute.net/chronycontrol.html + +ChronyControl provides a gui wrapper for installing these files and sets the +necessary permissions on each file. + + +Install the chrony software +--------------------------- + +You will need xcode and the commandline additions to build and install chrony. +These can be obtained from Apple's website via the App Store. + +cd to the chrony directory +./configure +make +sudo make install + +chrony is now installed in default locations (/usr/local/sbin/chronyd, +/usr/local/bin/chronyc) + +Create a chrony.conf file - see the chrony website for details + +The support files here assume the following directives are specified in the +chrony.conf file + +keyfile /etc/chrony.d/chrony.keys +driftfile /var/db/chrony/chrony.drift +bindcmdaddress /var/db/chrony/chronyd.sock +logdir /var/log/chrony +dumpdir /var/db/chrony + +Install this file as /etc/chrony.d/chrony.conf and create +the directories specified in the above directives if they don't exist. +You will need root permissions to create the directories. + + +Running chronyd +--------------- +At this point chronyd *could* be run as a daemon. Apple discourage running +daemons and their preferred method uses the launchd facility. The +support files here provide a launchd configuration file for chronyd and also +a shell script and launchd configuration file to rotate the chronyd logs on a daily basis. + + +Support files +------------- +Dates and sizes may differ +-rw-r--r-- 1 yourname staff 2084 4 Aug 22:54 README.txt +-rwxr-xr-x 1 yourname staff 676 4 Aug 21:18 chronylogrotate.sh +-rw-r--r-- 1 yourname staff 543 18 Jul 20:10 org.tuxfamily.chronyc.plist +-rw-r--r-- 1 yourname staff 511 19 Jun 18:30 org.tuxfamily.chronyd.plist + +If you have used chrony support directories other than those suggested, you +will need to edit each file and make the appropriate changes. + + +Installing the support files +---------------------------- + +1. chronylogrotate.sh +This is a simple shell script that deletes old log files.
