This document explains how to update H-Sphere MySQL servers to version 4.0.16 on Linux and
version 4.0.17 on FreeBSD. The update is performed on the control panel server as root and
affects all H-Sphere boxes running MySQL.
H-Sphere apache has MySQL support enabled. Therefore, if a MySQL box runs a WEB
server, the following packages will also be reinstalled:
As a result, the libphp4.so file (apache php module) will be updated, too.
The update applies only to standard apache installations.
If you have customized H-Sphere apache modules, for instance PHP, or mod_throttle,
you'll have to recompile them after the upgrade.
If you have added custom apache modules, such as mod_gzip or mod_security, you'll have to
disable them before the upgrade, then recompile and add them after the upgrade.
- Log into the control panel server as root:
- Back up the file /hsphere/shared/apache/libexec/libphp4.so if applicable
- Untar the archive:
# tar xfz u-mysql.tgz
- Enter the u-mysql directory:
# cd u-mysql
- Run the update script
# sh update.sh
If Apache restarts, but sites do not come up, and apache log file
/hsphere/local/var/httpd/log/error_log contains errors like
"segmentation fault" or "child crashed", make sure to recompile custom
Apache modules you may have installed, such as mod_gzip, mod_security, etc.
