文系男子が日和るIT開発~IT知識なしで飛び込んだIT企業

文系男子だからIT企業に就職するなんて考えてもみませんでしたが、日和ながら日々くらいついています。

CentOS6.8からCentOS7系へアップデートにチャレンジも劣悪なネットワーク環境とpreupgコマンドに泣かされる

CentOS6.8からCentOS7へのアップデートにチャレンジ。

下調べは、特にしていないのですが、ググってみてもCentOS 6.8からCent OS 7への 移行されている方があまりいらっしゃらないようで、マイノリティな移行なようです。

手順はわからないですが、とにかくチャレンジ!

 

 まずは、現行のバージョンの確認を行います。

uname -a

cat /etc/redhat-release

これらのコマンドを実行し、バージョンを確認します。
CentOSはご覧の通り

 

6.8となります。

 

[admin@localhost ~]$ uname -a
Linux localhost.localdomain 2.6.32-642.3.1.el6.i686 #1 SMP Tue Jul 12 17:53:37 UTC 2016 i686 i686 i386 GNU/Linux
[admin@localhost ~]$
[admin@localhost ~]$ cat /etc/redhat-release
CentOS release 6.8 (Final)

 

アップデート前に最新化 

yum -y update

[root@localhost ~]# 

[root@localhost ~]# yum -y update

この203MByteのパッケージのダウンロードがどうしてもできず断念。

理由は、我が家の劣悪なネットワーク環境のせいで、この時間帯(寒い土曜日の22時頃)は、時折下り1kb/sを下回るほどひどい状況で、タイムアウトエラーによりダウンロードが終了するためです。

 ちなみに回線は@niftyのADSL39MBのプラン。

スマホテザリングのほうが当然早い環境ながら、スマホは格安SIMとして、OCNのモバイルONEで1日あたりの使用量に上限を設けているプランのせいで、テザリングにもよるダウンロードは断念。

 

 

そして翌日、今日日曜の22時に再チャレンジ。

とりあえず yum check-update を試みる。

 何とかダウンロードでけた模様。

 

ここからが問題。知識がないところ。

他のブロガー様の実施方法を参考にさせていただくしだいです。

 

なんでも、ここでCent OS7へアップデートに必要なパッケージを取得していきます。

yum install -y openscap pcre-devel libxml2-devel libxslt-devel m2crypto python-simplejson
yum install -y mod_wsgi redhat-upgrade-tool preupgrade-assistant-contents

  

とりあえずコマンド実行してみます。

 相川らずTimeoutしまくるネット環境。

それに負けずに進めていましたが、

No package redhat-upgrade-tool available.
No package preupgrade-assistant-contents available.
Nothing to do

というメッセージが気になります。

 

が、進めます。

preupg -s RHEL6_7

を実行します。

 

 

が、

[admin@localhost ~]$ preupg -s RHEL6_7
bash: preupg: command not found
 

[admin@localhost ~]$ which preupg
/usr/bin/which: no preupg in (/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/admin/bin)

 

preupgがありませんでした。

 

http://dev.centos.org/centos/6/upg/x86_64/Packages/

ここからwgetでダウンロードしていくのでしょうか?
試してみたいですが、、、、ネットワーク環境に阻まれる。。。。

 

ネットワークが重いと、色々試したいときに腰も重くなりますね・・・

 

 

ここまでとします。
