The ISPConfig update script is an easy way to update an ISPConfig 3 installation. If you want to create a manual backup of ISPConfig, take a look at the instructions at the end of the article.
To update ISPConfig 3, login as root user on the shell of your server and run the command:
ispconfig_update.shIf you want to force an update in case your current version is the same, use --force option.
ispconfig_update.sh --force
The update process in detail
ispconfig_update.sh
> Update
Please choose the update method. For production systems select 'stable'.
The update from svn is only for development systems and may break your current setup.
Select update method (stable,svn) [stable]:
You should always select "stable" on a production system. The "svn" version is only suitable for ISPConfig 3 development.
The updater will then check the version of your system, download the latest update and starts the update process.
This application will update ISPConfig 3 on your server.
Shall the script create a ISPConfig backup in /var/backup/ now? (yes,no) [yes]:
You should choose "yes" here. This will create a backup of the ISPConfig scripts (/usr/local/ispconfig), the /etc directory and the ISPC0nfig MySQL database in the directory /var/backup/
Creating backup of "/usr/local/ispconfig" directory...
Creating backup of "/etc" directory...
Checking ISPConfig database .. OK
Starting incremental database update.
The update script will then start to install incremental database updates for ISPConfig, if required.
Reconfigure Permissions in master database? (yes,no) [no]:
If this is a slave server in a multiserver setup, then choose "yes" here on at least one of the slave servers. For single server installations, choose 'no'. Then you were asked if the services shall be reconfigured:
Reconfigure Services? (yes,no) [yes]:
You should choose "yes" here, only if you modified your system configuration manually, it might be better to choose no. But in this case, new features in ISPConfig might not work or functions might stop working until you adjusted the config files manually. So its always a good choice to select 'yes' here. In the next step, select the ispconfig port:
ISPConfig Port [8080]:
Port 8080 is the default, if you have not changed it, press enter. Otherwise enter the port number and then press enter. As the last step, you wre asked if the crontab shall get reconfigured, you can select yes here by just pressing return.
Create new ISPConfig SSL certificate (yes,no) [no]:
If your SSL certificate for the ISPConfig interface has been expired and you want to renew it or if you want to enable SSL encryption for the ISPConfig interface, then choose "yes". If you dont need a new SSL certificate, take the default (no).
Reconfigure Crontab? (yes,no) [yes]:
The ISPConfig updater will then update the ispconfig files and restart services, if the configuration has been changed.
Backup before updates
(This backup procedure is now integrated into the ISPConfig updater and gets executed automatically when you choose to create a backup during update)
Before you update a software, it is always a good idea to backup all relevant data. This enables you to restore the software version that you had before in case of an error. The steps to create a backup of the ispconfig software and settings are:
Create a backup folder:
mkdir /home/backup
chmod 700 /home/backup
cd /home/backupBackup the database
mysqldump -u root -p dbispconfig > dbispconfig.sqlBackup the ISPConfig software
tar pcfz ispconfig_software.tar.gz /usr/local/ispconfigBackup the configuration files in /etc
tar pcfz etc.tar.gz /etcThis backup does not include the emails and website data.
