_ RaspberryPiを再び (9) -apache-
せっかくなので今まで避けてきたhttp serverにも挑戦してみる。
packageはapache2となっている。
$ sudo apt install apache2
$ sudo service apache2 start
$ sudo systemctl restart apache2
$ cd /etc/apache2
$ cat apache2.conf
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.4/ for detailed information about
# the directives and /usr/share/doc/apache2/README.Debian about Debian specific
# hints.
#
#
# Summary of how the Apache 2 configuration works in Debian:
# The Apache 2 web server configuration in Debian is quite different to
# upstream's suggested way to configure the web server. This is because Debian's
# default Apache2 installation attempts to make adding and removing modules,
# virtual hosts, and extra configuration directives as flexible as possible, in
# order to make automating the changes and administering the server as easy as
# possible.
# It is split into several files forming the configuration hierarchy outlined
# below, all located in the /etc/apache2/ directory:
#
# /etc/apache2/
# |-- apache2.conf
# | `-- ports.conf
# |-- mods-enabled
# | |-- *.load
# | `-- *.conf
# |-- conf-enabled
# | `-- *.conf
# `-- sites-enabled
# `-- *.conf
#
#
# * apache2.conf is the main configuration file (this file). It puts the pieces
# together by including all remaining configuration files when starting up the
# web server.
#
# * ports.conf is always included from the main configuration file. It is
# supposed to determine listening ports for incoming connections which can be
# customized anytime.
#
# * Configuration files in the mods-enabled/, conf-enabled/ and sites-enabled/
# directories contain particular configuration snippets which manage modules,
# global configuration fragments, or virtual host configurations,
# respectively.
#
# They are activated by symlinking available configuration files from their
# respective *-available/ counterparts. These should be managed by using our
# helpers a2enmod/a2dismod, a2ensite/a2dissite and a2enconf/a2disconf. See
# their respective man pages for detailed information.
#
# * The binary is called apache2. Due to the use of environment variables, in
# the default configuration, apache2 needs to be started/stopped with
# /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not
# work with the default configuration.

_ RaspberryPiでFreeBSDを動かす。(6)
とりあえずRaspbianについては一通り動くようになったのでRPI-2で使うことにして、
RPI-Bでは以前挑戦してそのままになったFreeBSDを動かしてみることにした。
近いmirror siteであるhttp://ftp.jaist.ac.jp/pub/FreeBSD/snapshots/ISO-IMAGES/12.1/から
FreeBSD-12.1-STABLE-arm-armv6-RPI-B-20200514-r361020.img.xzを落としてSDカードに書き込んだ。

_ RaspberryPiを再び (6) -update-alternatives-
Raspbian上でPythonを使った処理系を使おうと思ってinstallされているPythonのversionを確認したところ、
$ python --version
Python 2.7.16
$ python2 --version
Python 2.7.16
$ python3 --version
Python 3.7.3Pythonに限らず複数のversionのものが経蔵されているコマンドのdefaultを変更するにはupdate-alternativesを使うようである。 まずはPythonがupdate-alternativesで管理されているかどうかを確認する。
$ update-alternatives --list python
update-alternatives: エラー: python の alternatives がありません
$ sudo update-alternatives --install /usr/bin/python python /usr/bin/python2.7 1
$ sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.7 2
$ sudo update-alternatives --list python
/usr/bin/python2.7
/usr/bin/python3.7
$ python --version
Python 3.7.3
$ sudo update-alternatives --config python
alternative python (/usr/bin/python を提供) には 2 個の選択肢があります。
選択肢 パス 優先度 状態
