When I am doing a fresh install of a box, I use the generated stage3 to |
| 10 |
start with, and the same portage snapshot. That is the easy part ;) |
| 11 |
|
| 12 |
Once the box is installed, I need a safe environment to maintain it. |
| 13 |
Generally I do upgrades a) every quarter or b) when a glsa requires it. To |
| 14 |
upgrade I download the new portage snapshot, change the snapdate: in the |
| 15 |
spec file, do the upgrade (with buildpkg in FEATURES). The new packages |
| 16 |
will be generated in packages/NEWDATE. If anything goes wrong I can fix it |
| 17 |
within the buildhost before rolling it out to the servers. If anything |
| 18 |
goes terribly wrong I can roll back to a stable state by changing the |
| 19 |
snapdate back, ditching the entire buildhost and its newly generated |
| 20 |
packages, re-creating from the original stage3... |
| 21 |
|
| 22 |
To populate new binary packages to the target servers, on the build server I |
| 23 |
have rsyncd set up to publish all of the snapshots/overlays, apache set up |
| 24 |
to publish the binary packages: |
| 25 |
|
| 26 |
/etc/rsyncd.conf entries: |
| 27 |
|
| 28 |
[snapshots] |
| 29 |
path = /var/buildhoster/snapshot_cache |
| 30 |
read only = yes |
| 31 |
exclude = distfiles/ packages/ |
| 32 |
|
| 33 |
[overlays] |
| 34 |
path = /var/buildhoster/overlays |
| 35 |
read only = yes |
| 36 |
exclude = .svn/ |
| 37 |
|
| 38 |
apache entries: |
| 39 |
Alias /packages/ /var/buildhoster/packages/ |
| 40 |
|
| 41 |
|
| 42 |
Corresponding entries in the target server make.conf: |
| 43 |
SYNC="rsync://buildserver.example.net/snapshots/portage-20060404/portage" |
| 44 |
PORTAGE_BINHOST="http://buildserver.example.net/packages/myserver/20060404/All/" |
| 45 |
|
| 46 |
So the basic process to update the target server goes: |
| 47 |
sync any overlays |
| 48 |
sync portage |
| 49 |
emerge -Dug world |
