sadm_push_sadmin.sh
NAME
sadm_push_sadmin.sh - Push SADMIN version to one or all actives clients.
SYNOPSIS
sadm_push_sadmin.sh [-d 0-9] [-h] [-n hostname ] [-s] [-u] [-v]
DESCRIPTION
This script copy the SADMIN version of the master to one or all actives clients. If you want to update only one client, use the command line option ‘-n’ and specify the hostname to update. Let’s say you have just updated your SADMIN master server and you want to update all your clients, this is the script to run. By default, this script is not part of any crontab job, so you need to execute it manually or place it in the server crontab (/etc/cron.d/sadm_server). Non-active clients (status set to inactive in CRUD) are ignored. Directories others than the one specified below are left untouched on the client. So don’t worry, it will update only SADMIN files and scripts, your SADMIN configuration files, scripts (in $SADMIN/usr/bin) are left untouched by this push.
- Use the ‘-s’ to push the startup & shutdown script to all your clients. This option is useful if you are using the same startup and shutdown scripts for all your clients.
- The ‘-u’ option allow you to also push the “$SADMIN/usr” directories to the clients.
Operations done for each active clients :
- Verify if SSH connection to client is working.
- Get the directory where SADMIN is install on client via ‘/etc/environment’.
- Copy scripts directory ($SADMIN/bin) to corresponding client directory.
- Copy packages directory ($SADMIN/pkg) to client directory.
- Copy libraries directory ($SADMIN/lib) to client directory.
- Copy the alert group and Slack configuration files to client directory.
- If user directory option is used (‘-u’).
- Copy user directories ($SADMIN/usr/bin,$SADMIN/usr/lib,$SADMIN/usr/cfg) to client.
- Copy dot configuration template files from ($SADMIN/cfg) to client directory.
- Copy dot configuration template files from ($SADMIN/sys) to client directory.
- If system startup/shutdown directory option is used (‘-s’).
- Copy customized scripts of Startup/Shutdown ($SADMIN/sys) to client.
- See how to use the startup/shutdown script with sadm_service.sh
- System Monitor scripts and templates
- Copy ‘nmon’ watcher scripts ($SADMIN/usr/mon/swatch_nmon.sh) to client.
- Copy ‘nmon’ error text file ($SADMIN/usr/mon/swatch_nmon.txt) to client.
