munin apache server-status

When you want to monitor Apache with Munin, you have to let Munin node access the extended server status. The server status is available on http://server/server-status and it has to be secured. Firts, enble Extended Server Status. In httpd.conf (or whatever is used by you installation) ExtendedStatus On Second, in the same file: <Location /server-status>     SetHandler server-status     Order deny,allow     Deny from all     Allow from </Location> With these settings, you should get Apache accesses graph on Munin.

CentOS6 packaging basic environment

When working on packaging some unpackaged yet software for CentOS, I often start with a clean minimal VM and then setup a new development+packaging environment. This becomes repetitive so that I needed a memo in order to just copy/paste. Note that this is just the very basic packaging tools I need and this does not override any official packaging guide. sudo yum -y install rpm-build rpmdevtools redhat-rpm-config make gcc autoconf automake gcc-c++ yum-utils sudo yum -y groupinstall "Development Tools" Then I install the complete build dependencies depending on the package I want to build. After this, I have to setup a minimal build environment: mkdir -p ~/rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS} echo '%_topdir %(echo $HOME)/rpmbuild' > ~/.rpmmacros When building with "rpmbuild" I might encouter some insatisfied build dependencies. This is solved with  yum-builddep /path/to/package.spec

Libvirt KVM fixed IP address

When playing with KVM LibVirt Vms, I often need them to have fixed IP address. Ironically, I enjoy fixing them with DHCP. Here is the “default” configuration I use in order to fix them. Redefining the "default" network is done with: virsh --connect qemu:///system net-destroy default virsh --connect qemu:///system net-undefine default virsh --connect qemu:///system net-define /tmp/network.xml virsh --connect qemu:///system net-start default Feel free to get inspiration: < network > < name >default</ name > < uuid >7efbc96f-94e8-443f-820c-615d2e0331d5</ uuid > < forward mode = 'nat' /> < bridge name = 'virbr0' stp = 'on' delay = '0' /> < ip address = '' netmask = '' >
