netdataをアップデートしようとしたらエラーになった

netdata でサーバの状態観察をしているのだが、アップデート要求が出ていた

OracleLinux8環境でセットアップしており、下記のパッケージでインストールされていた。

とりあえずお知らせ記載の「wget -O /tmp/netdata-kickstart.sh https://my-netdata.io/kickstart.sh && sh /tmp/netdata-kickstart.sh 」を実行したところエラーとなった

  You are about to install netdata to this system.
  netdata will be installed at:

                    /opt/netdata

  The following changes will be made to your system:

  # USERS / GROUPS
  User 'netdata' and group 'netdata' will be added, if not present.

  # LOGROTATE
  This file will be installed if logrotate is present.

   - /etc/logrotate.d/netdata

  # SYSTEM INIT
  If a supported init system is detected, appropriate configuration will be
  installed to allow Netdata to run as a system service. We currently support
  systemd, OpenRC, LSB init scripts, and traditional init.d setups, as well as
  having experimental support for runit.


  This package can also update a netdata installation that has been
  created with another version of it.

  Your netdata configuration will be retained.
  After installation, netdata will be (re-)started.

  netdata re-distributes a lot of open source software components.

Rstudio Serverの設定で分からなかったことのメモ

Rstudio ServerをRHEL9環境にインストールした際に悩んだことのメモ

その1: 新規作成プロジェクトでのpythonパスを指定したい

ユーザのホームディレクトリに「.Renviron」というファイルを作って 環境変数 RETICULATE_PYTHON を定義する。

RETICULATE_PYTHON="/usr/local/python3/bin/python"

なお、今回は~/.Renviron ファイルを使ったが、「Managing R with .Rprofile, .Renviron, Rprofile.site, Renviron.site, rsession.conf, and repos.conf」の記述を見ると、いろいろある。

システム全体の設定としては $R_HOME/etc/Renviron がある。

検証環境の場合 /opt/R/4.1.3/lib/R/etc/Renviron にあった

### etc/Renviron.  Generated from Renviron.in by configure.
###
### ${R_HOME}/etc/Renviron
###
### Record R system environment variables.

## As from R 4.0.0 the C code reading this follows the POSIX rules
## for parameter substitution in shells, section 2.6.2 of
## https://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18
## In earlier versions ${FOO-bar} was interpreted the same as ${FOO:-bar}

R_PLATFORM=${R_PLATFORM-'x86_64-pc-linux-gnu'}
## Default printer paper size: first record if user set R_PAPERSIZE
R_PAPERSIZE_USER=${R_PAPERSIZE}
R_PAPERSIZE=${R_PAPERSIZE-'letter'}
## Default print command

#R_LIBS_USER=${R_LIBS_USER-'~/Library/R//4.1/library'}

### Local Variables: ***
### mode: sh ***
### sh-indentation: 2 ***
### End: ***

しかし、これを直接編集はしてはいけない。

/opt/R/4.1.3/lib/R/etc/Renviron.site というファイルを新規で作成し、 「RETICULATE_PYTHON=”/usr/local/python3/bin/python”」とか書くことで全体適用となる。

これは、/opt/R/4.1.3/lib/R/etc/Renviron の方は、Rのバージョンアップで設定値が変わる可能性があるので、特有の設定はファイルを分離しておく、というものになっている。

その2: アクセスログ

Rstudio ServerのWeb UIから誰がログインしたのか、というログがどこに出るのか?

どうやら、Pro版のみの機能の模様で、 /etc/rstudio/rserver.conf に「server-access-log=1」と設定するようだが、ライセンスがないと、この設定が入っているとRstudio serverが起動しない。

わざとパスワードを間違えたりすると /var/log/secure にログがでるので、/etc/pam.d/rstudio の内容を/etc/pam.d/sshd と同じにすれば、rstudioでログインに成功した場合でも同じようにログイン成功時もログ出力があるかと思ったのですが、出力されず。

・・・ただ、pamtesterコマンドで動作検証してみたところ、rstudioでもsshdでもログイン成功時に出力していない・・・もしかしてsshでログイン成功した時に/var/log/secureに出力しているのはpamd経由ではない??

rstudioでパスワード間違え

[root@rhel9 rstudio]# pamtester -v rstudio testuser authenticate
pamtester: invoking pam_start(rstudio, testuser, ...)
pamtester: performing operation - authenticate
Password:
pamtester: Authentication failure
[root@rhel9 rstudio]#

/var/log/secureの出力内容

Apr  5 17:50:51 rhel9 unix_chkpwd[41719]: password check failed for user (testuser)
Apr  5 17:50:51 rhel9 pamtester[41717]: pam_unix(rstudio:auth): authentication failure; logname=root uid=0 euid=0 tty= ruser= rhost=  user=testuser

rstudioでパスワード正しく

[root@rhel9 rstudio]# pamtester -v rstudio testuser authenticate
pamtester: invoking pam_start(rstudio, testuser, ...)
pamtester: performing operation - authenticate
Password:
pamtester: successfully authenticated
[root@rhel9 rstudio]#

/var/log/secureへの出力は無い

sshdでパスワード誤り

pamtester: invoking pam_start(sshd, testuser, ...)
pamtester: performing operation - authenticate
Password:
pamtester: Authentication failure

/var/log/secureへ出力あり

Apr  5 17:51:09 rhel9 unix_chkpwd[41726]: password check failed for user (testuser)
Apr  5 17:51:09 rhel9 pamtester[41724]: pam_unix(sshd:auth): authentication failure; logname=root uid=0 euid=0 tty= ruser= rhost=  user=testuser

sshdでパスワード正しく

pamtester: invoking pam_start(sshd, testuser, ...)
pamtester: performing operation - authenticate
Password:
pamtester: successfully authenticated

/var/log/secureに出力無し

Rstudio server上でRを使う時に追加しておいた方がいいRHELパッケージのメモ

Rstudio serverをRHEL9上で動かす際にR側でいろいろパッケージを追加する際に必要となるパッケージがあったので、そのメモ

まずは基本

「dnf groupinstall “開発ツール”」で開発ツールをインストール

tidyverseに必要だったもの

install.packages(“tidyverse”) でtidyverseを追加しようとしたら前提となるraggのインストールがfontconfigコマンドが無いことで失敗

→ fontconfig-devel

次のエラーがfribidi was not found in the pkg-config search path

→ fribidi-devel
→ libtiff-devel
→ libjpeg-turbo-devel

Rstudioからpythonを使う際に必要だったもの

Rstudio serverでpythonスクリプトを使う際に、追加パッケージを要求されるが、それが必要としているもの

→ libxml2-devel
→ libcurl-devel
→ libpng-devel

HPE Superdome Flex 280サーバーではLinuxのサポートについて注意が必要(現状RHEL9.0はサポートしない)

2022/12/05追記:2022/11/30にRHEL9.0対応のI/O Service Pack for HPE Superdome Flex Servers Familyがリリースされてました。


HPE Superdome Flex 280サーバーを導入するにあたってLinuxのサポートも必要という話で、RedHat Enterprise Linuxを導入する、という話になった。

ドキュメントを探すと「Installing Operating Systems on HPE Superdome Flex 280 Server」がもっともまとまっている感じだった。

ここの「Supported operating systems」には下記の様に書かれている。

HPE Foundation Software (HFS) version support matrix」を見るとRHEL9.0をサポートしていると読める記述がある。

Software Delivery Repositoryにある「HPE Foundation Software Repository」を見ても指定できるディストリビューションバージョンに9.0が含まれている。

ISOファイルとして入手する場合は「HPE Foundation Software ISO Image for HPE Superdome Flex Servers Family」から入手でき、RHEL9/Oracle Linux 9がサポート対象として記載されている。

上記ページにリンクがある「Running Linux on HPE Superdome Flex 280 Server」は冒頭の「Installing Operating Systems on HPE Superdome Flex 280 Server」を切り出した感じのドキュメントになってようにみえ、特にRHEL9がサポートされない、という認識ではなかった。

しかし!

hpeから、2022年11月2日時点で、HPEがサポートするのはRHEL8.5までで、RHEL8.6とRHEL9.0は現状はサポートしない、との通告を受けた。

なぜ?と聞くと「I/O Service Pack」の対応バージョンが出ていないから、という

確認してみると「Running Linux on HPE Superdome Flex 280 Server」の方には記述がないが、「Installing Operating Systems on HPE Superdome Flex 280 Server」には「HPE Superdome Flex 280 Server I/O Service Pack」という項目がある・・・

しかし、「Customers can use the HPE Superdome Flex 280 Server I/O Service Pack」という表現なので「要求」じゃないはずなのに、要求されている。

ダウンロードリンクは「I/O Service Pack for HPE Superdome Flex Servers Family

firmwareとdriverを新しいものに更新するために使うので、必須ではないはずなのだが、hpeサポートは必須と主張してくる感じです。

じゃあ、RHEL9.0対応版はいつでるの?ときいいてみるものの「不明」という回答。

大丈夫なんか?HPE


2022/11/14追記

RHEL9をサポートするI/O Service Packのリリース見込みがついた、という連絡があったので、とりあえず本件はなんとかなりそう


2022/12/05追記

2022/11/30付けでRHEL8.6とRHEL9.0に対応した「I/O Service Pack for HPE Superdome Flex Servers Family 2022.09」がリリースされていました。

閉鎖環境内でアラートメールの送信ができるだけのためのメールサーバ設定(AlmaLinux8/RHEL8/Oracle Linux8)

閉鎖環境で機器初期セットアップを行う際に、アラートメールの送信先を指定する必要があったりする。

その時に、メール送信テストが行えるような簡易的なLinuxサーバを作るためのメモ書きです。

なお、メールの送信先は「root@adosakana.local」としておいて、Linuxユーザのroot宛にメールが届くような設定です。

メールを読むときは /var/mail/root に届くのを直接見るか、mail/mailx/muttコマンドなどで見る想定です。

(1) AlmaLinux / RHEL / Oracle Linux 8の最小インストールを実施

(2) アップデート

「dnf update -y」でパッケージを最新に

(3) SMTPで使用するポート開け

「firewall-cmd –add-service smtp –permanent」で追加

# firewall-cmd --list-all
public (active)
  target: default
  icmp-block-inversion: no
  interfaces: ens192
  sources:
  services: cockpit dhcpv6-client ssh
  ports:
  protocols:
  forward: no
  masquerade: no
  forward-ports:
  source-ports:
  icmp-blocks:
  rich rules:
# firewall-cmd --add-service smtp --permanent

# firewall-cmd --reload

# firewall-cmd --list-all
public (active)
  target: default
  icmp-block-inversion: no
  interfaces: ens192

  ports:
  protocols:
  forward: no
  masquerade: no
  forward-ports:
  source-ports:
  icmp-blocks:
  rich rules:
#

(4) postfixのインストール

「dnf install postfix」でpostfixをインストール

(5) postfixの設定ファイルを編集

まず、テストに使うメールアドレスのドメイン名を「mydomain=~」で定義(myhostname 定義はそのまま使った)

# The mydomain parameter specifies the local internet domain name.
# The default is to use $myhostname minus the first component.
# $mydomain is used as a default value for many other configuration
# parameters.
#
#mydomain = domain.tld
mydomain = adosakana.local

メール送信者にドメイン名指定がない場合に、mydomainで設定した内容を適用するために「myorigin = $mydomain」

# SENDING MAIL
#
# The myorigin parameter specifies the domain that locally-posted
# mail appears to come from. The default is to append $myhostname,
# which is fine for small sites.  If you run a domain with multiple
# machines, you should (1) change this to $mydomain and (2) set up
# a domain-wide alias database that aliases each user to
# user@that.users.mailhost.
#
# For the sake of consistency between sender and recipient addresses,
# myorigin also specifies the default domain name that is appended
# to recipient addresses that have no @domain part.
#
#myorigin = $myhostname
myorigin = $mydomain

どのNICからきたSMTP要求でも受付させるための「inet_interfaces = all」を定義

# RECEIVING MAIL

# The inet_interfaces parameter specifies the network interface
# addresses that this mail system receives mail on.  By default,
# the software claims all active interfaces on the machine. The
# parameter also controls delivery of mail to user@[ip.address].
#
# See also the proxy_interfaces parameter, for network addresses that

受信するメールを決めるために「mydestination =~」を指定。とりあえず全部受け取るような感じの設定にする

# Specify a list of host or domain names, /file/name or type:table
# patterns, separated by commas and/or whitespace. A /file/name
# pattern is replaced by its contents; a type:table is matched when
# a name matches a lookup key (the right-hand side is ignored).
# Continue long lines by starting the next line with whitespace.
#
# See also below, section "REJECTING MAIL FOR UNKNOWN LOCAL USERS".
#
#mydestination = $myhostname, localhost.$mydomain, localhost
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
#mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain,
#       mail.$mydomain, www.$mydomain, ftp.$mydomain

メール送信側のSSLプロトコル対応が古い場合を考慮して「smtpd_tls_security_level=none」と暗号化の要求レベルをなしにしておく

# Announce STARTTLS support to remote SMTP clients, but do not require that
# clients use TLS encryption (opportunistic TLS inbound).
#
#smtpd_tls_security_level = may
smtpd_tls_security_level = none

なお、「lost connection after STARTTLS from unknown」という形でSMTP接続を拒否される場合は、おそらく標準値の「smtpd_tls_security_level = may」で設定している場合。(TLS1.2以降を必須、とかそんな感じ)

(6) postfixを起動

「systemctl enable postfix」でOS起動時にpostfixも起動するように設定し、

「systemctl start postfix」でいますぐpostfixを起動させている

# systemctl status postfix
● postfix.service - Postfix Mail Transport Agent
   Loaded: loaded (/usr/lib/systemd/system/postfix.service; disabled; vendor pr>
   Active: inactive (dead)
# systemctl enable postfix
Created symlink /etc/systemd/system/multi-user.target.wants/postfix.service → /usr/lib/systemd/system/postfix.service.
# systemctl status postfix
● postfix.service - Postfix Mail Transport Agent
   Loaded: loaded (/usr/lib/systemd/system/postfix.service; enabled; vendor pre>
   Active: inactive (dead)
# systemctl start postfix
#


おまけ: mutt コマンドでメールを送信しようとしたけど、送れない

とあるプロダクトのアラートメールの送信手法がmuttコマンドを利用していた。

「smtpd_tls_security_level = may」設定のpostfixにメールを送ると「lost connection after STARTTLS from unknown」で送れていなかった。

postfix側ではなく、mutt側で対策取れるかを確認したところ /etc/Muttrc.local などの muttの設定ファイル内で「set ssl_starttls = no」と設定して、STARTTLSの使用を取りやめることでメール送信に成功するようになった。

RHEL8.5サーバから mutt コマンドでメール送信する場合、SSL関連の設定を調べると以下の様なものがある

set ssl_verify_host = no
set ssl_verify_dates = no
set ssl_starttls = yes
set ssl_use_tlsv1_3 = yes
set ssl_use_tlsv1_2 = yes
set ssl_use_tlsv1_1 = yes
set ssl_use_tlsv1 = no
set ssl_use_sslv3 = no
set ssl_use_sslv2 = no

ただ、RHEL8.5で試してみたところ「ssl_use_sslv2」というオプションは存在していなかった。

# echo "test mail"  | mutt -F ~/testmuttrc -s "test mail title" 受信者 -d 10
レベル 10 でデバッグ中。
/root/testmuttrc 中の 14 行目でエラー: ssl_use_sslv2 は不明な変数
source: /root/testmuttrc 中でエラー
#

また、opensslコマンドのs_clientでSSLv2 SSLv3の接続ができるかを試験してみたところ、オプション自体が廃止されていた。

# openssl s_client -connect 172.17.44.50:25 -servername 172.17.44.50 -ssl3
s_client: Option unknown option -ssl3
s_client: Use -help for summary.
# openssl s_client -connect 172.17.44.50:25 -servername 172.17.44.50 -ssl2
s_client: Option unknown option -ssl2
s_client: Use -help for summary.
