Scicentific Linux 7.6にUpgrade ＝ = サーバ運営の今後を考える
February 20, 2019 – 11:48 am昨年の12月3日付でScieientific Linux 7.6がリリースされていた。2カ月遅れとなったが、このリリースを受け、我がサーバのOSを更新した。
前回の更新作業は、一昨年の12月4日のLinux7.4へのUpgradeで、今回の更新作業はVers.7.5（昨年5月にリリース）をスキップしている。前回の更新作業では、Linuxのカーネルは正常に更新されていたが、versionの標識(/etc/redhat-release)が更新されておらず、多少の不安を残すものになっていた。
以下、更新作業のlogを掲げるとともに、多少、このサーバの今後の運営について考えたのでメモしておいた。
サーバ運営の今後（CentOSへの変更を検討）：
Scientific Linuxは、CentOSとともに、Redhat社のRHEL（Red Hat Enterprize Linux)のクローンであり、今回のVers.7.6のリリースは、RHEL7.6のリリースから約2カ月遅れのものである。我がサーバでは、2011年3月以前はCentOSを、それ以降はScientific Linxuを採用することにしていた。Scientific Linuxへの変更はCentOSグループ内の混乱が報じられ、RHELのVersion更新への反映に遅れが生じたことによる。
2014年以降、RHELとCentOSが協力する体制ができ、CentOSの体制が整ってきたこともあり、我がサーバのOSを、現在のScientific Linuxから CentOSへの変更を検討することにし、具体的な作業をはじめている。今後、CentOSの導入作業をこのブログ上に逐次掲載する予定。
Scientific Linux 7.6へのUpgrade時のlog:
CentOSへの移行計画はそれはそれとして、今回のScientific LinuxのVers. 7.6へのUpgradeに係るlogを以下に掲ておく：
