RockyLinux9.5で、Postfix+Mailman3をVirtuelEnvを使ってインストールする

Last updated at Posted at 2021-12-05

メーリングリストでシェアの高いMailman。Sendmail時代にfmlと共に主流だったメーリングリストの仕組みは、今ではPostfix+Mailman2での構成をよく見かけます。
本構成は、Postfix+Mailman2の構成を行います。Mailman3は、Dockerコンテナなど様々な提供方法がありますが、本記事では、Python3.xとVirtualEnv機能を利用して、OSにインストールを行います。

0.あらかじめ準備をするもの

Postfix

  • [Postfix+PostfixAdminでマルチドメイン対応のメールサーバーを作成する for RockyLinux 8.5](Postfix+PostfixAdminでマルチドメイン対応のメールサーバーを作成する for RockyLinux 8.5)

Python 3.x

Apache 2.4

Apache2.4をインストールする(ソースからコンパイル) for RockeyLinux 8.4 (systemd対応)

MariaDB(MySQL) or PostgreSQL ※本ページではMariaDBをベースに紹介

MariaDB11.6.xのインストール（ソースからコンパイル）for RockyLinux 9.x and Ubuntu 22.04.2

必要なパッケージ

dnf install sassc

1.Pythonを入れる

cd /usr/local/src
wget https://www.python.org/ftp/python/3.12.8/Python-3.12.8.tgz
tar xvzf Python-3.12.8.tgz
cd Python-3.12.8

export CFLAGS="-I/usr/local/include -I/usr/local/ssl/include -L/usr/local/src/bzip2-1.0.8"
export LD_RUN_PATH=/usr/local/lib64:/usr/local/lib:/usr/local/ssl/lib:/usr/lib:/usr/lib64:/usr/local/mysql/lib
export PKG_CONFIG_PATH=/usr/local/ssl/pkgconfig:/usr/local/lib64/pkgconfig:/usr/local/lib/pkgconfig:/usr/lib:/usr/lib64/pkgconfig
#export LTOFLAGS="-flto -fuse-linker-plugin -ffat-lto-objects -flto-partition = none"

./configure \
--with-ensurepip \
--enable-shared \
--enable-ipv6 \
--with-openssl=/usr/local/ssl \
--enable-optimizations \
--prefix=/usr/local/python-3.10.2 \
--with-system-ffi=/usr/local/lib64 \
--enable-loadable-sqlite-extensions
make -j 8
make install

2.ユーザーを追加する

useradd -m -d /usr/local/mailman -s /usr/bin/bash mailman
sudo chown mailman:mailman /usr/local/mailman

設定フォルダを作成する

mkdir -p /etc/mailman3
chown mailman:mailman /etc/mailman3

3.VirtualEnvを構成する

sudo su mailman
cd /usr/local/mailman

#suでmailmanに入ったら自動でvenvに入る＋環境変数をセット
vi ~/.bashrc
---
export LD_LIBRARY_PATH=/usr/local/mysql/lib:/usr/local/python-3.12.8/lib:/usr/local/ssl/lib:/usr/local/ssl:/usr/local/lib64:/usr/local/lib:/usr/lib:/usr/lib64
export PKG_CONFIG_PATH=/usr/local/mysql/lib/pkgconfig:/usr/local/ssl/lib/pkgconfig:/usr/local/lib/pkgconfig:/usr/local/lib64/pkgconfig
export PATH=/usr/local/mysql/bin:$PATH

export CFLAGS="-I/usr/local/python-3.12.8/include/python3.12 -I/usr/local/mysql/include/mysql"
export LDFLAGS="-L/usr/local/python-3.12.8/lib/python3.12/site-packages"

#export MYSQL_LIB=/usr/local/mysql/lib

source /usr/local/mailman/venv/bin/activate
---

保存する

#環境設定を行う
/usr/local/python-3.12.8/bin/python3 -m venv venv
#ventの中に入る
source venv/bin/activate
#Updateする
python -m pip install --upgrade pip
#pip3 install tox



#指定バージョンのバイナリをインストールしておく
#https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/message/MZFWDTWVCFGH54WJDIQYUKEQ6WISME2P/
pip install mistune==2.0.0rc1

4.Mailman3をインストール (以下はrootで実行 )

併せて、PGSQLとMySQL対応にする

#export PATH=/usr/local/mysql/bin:$PATH
#export MYSQLCLIENT_CFLAGS=-I/usr/local/mysql/include/mysql
#export MYSQLCLIENT_LDFLAGS=-L/usr/local/mysql/lib
pip install wheel mailman psycopg2-binary mysqlclient

4.1 phpmysqlclientのインストールで、MariaDBのファイルとリンクしない

手動でインストールする（※必要に応じて利用する）

cd /usr/local/src
wget https://github.com/PyMySQL/mysqlclient/archive/refs/tags/v2.2.6.tar.gz
tar xvzf v2.2.6.tar.gz
cd mysqlclient-2.2.6
export #PKG_CONFIG_PATH=/usr/local/mysql/lib/pkgconfig:/usrt/local/ssl/lib/pkgconfig:/usr/local/python-3.12.8/lib/pkgconfig
#export CFLAGS="-I/usr/local/python-3.12.8/include/python3.12 -I/usr/local/mysql/include/mysql"
export LDFLAGS="-L/usr/local/python-3.12.8/lib/python3.12/site-packages -L/usr/local/mysql/lib"

makeファイルを書き換える

Makefile
.PHONY: build
build:
#python3で、インストールパスにに書き換える↓
         /usr/local/python-3.12.8/bin/python3 setup.py build_ext -if 

.PHONY: doc
doc:
        pip install .
        pip install sphinx
        cd doc && make html

.PHONY: clean
clean:
        find . -name '*.pyc' -delete
        find . -name '__pycache__' -delete
        rm -rf build

.PHONY: check
check:
        ruff *.py src ci
        black *.py src ci

Makeする

make

モジュールを確認する（正しくリンクしているか確認する）

cd /build/lib.linux-x86_64-cpython-312/MySQLdb
# ldd _mysql.cpython-312-x86_64-linux-gnu.so

cd ~
mailman-web migrate
mailman-web collectstatic
pip install libsass
mailman-web compress 
mailman-web compilemessages

12.Webアプリケーションの管理ユーザーを作成

su mailman
#unset LD_LIBRARY_PATH
pip install uwsgi

15.uwsgiの設定ファイルを準備する

/etc/mailman3/uwsgi.ini
cat > /etc/mailman3/uwsgi.ini << EOF

# /etc/mailman3/uwsgi.ini
#
[uwsgi]
# Port on which uwsgi will be listening.

log-route = qcluster uwsgi-daemons

# Last log and it logs the rest of the stuff.
logger = file:/usr/local/mailman/web/logs/uwsgi-error.log

EOF

16.mailmanwebの起動スクリプトを用意する

pip install whoosh
exit

19.サービスを起動・確認する

systemctl daemon-reload
systemctl start mailman3
systemctl enable mailman3
systemctl status mailman3
systemctl start mailmanweb
systemctl enable mailmanweb

mailman3を起動してもサービスが正常起動できない時がある。
この場合、サブプロセスがPythonのライブラリが見えてないために起動できていない可能性がある。
/usr/local/mailman/venv/bin/mailman start
で、起動時にどのような出力が出るかを確認して対処する。

ln -s /usr/local/python-3.12.8/lib/libpython3.12.so.1.0 /lib64/libpython3.12.so.1.0

で対応可能か確認する。

20.Cronの設定
