APIサーバをデーモンで動かすためのsupervisorの設定

Last updated at Posted at 2023-07-21

SupervisorとはPython製のプロセス管理ツール
プログラムなどを簡単にデーモン化することができる。

今回はEC2にデプロイしたGolangのAPIサーバをsupervisorで動かすことを想定する。

導入手順

bash
sudo yum install python3
sudo pip3 install supervisor
echo_supervisord_conf > ~/supervisord.conf

# 移動させる
sudo mkdir /etc/supervisord/
sudo mkdir /etc/supervisord/conf.d
sudo mv ~/supervisord.conf /etc/supervisord/supervisord.conf

# オリジナルとっとく
sudo cp /etc/supervisord/supervisord.conf /etc/supervisord/supervisord.conf.org

設定ファイルの作成

/etc/supervisord/supervisord.confの編集(長いから抜粋)

supervisord.conf
[inet_http_server]
port=127.0.0.1:9001 ; # superviserdを立ち上げるport。デバッグしたいときはnginxをここにつなげる
;username=user ; # ここら辺つけるとBasic認証みたいになる
;password=123

[supervisorctl]
;serverurl=unix:///tmp/supervisor.sock
serverurl=http://127.0.0.1:3000 ; # APIサーバを立ち上げるport

[include]
files = /etc/supervisord/conf.d/*.conf

権限の設定

実行権限をsupervisordにするため、serviceファイルを作成

bash
sudo touch /etc/systemd/system/supervisord.service

内容は以下

supervisord.service
[Unit]
Description=supervisord - Supervisor process control system for UNIX
Documentation=http://supervisord.org
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/bin/supervisord -c /etc/supervisord/supervisord.conf
ExecReload=/usr/local/bin/supervisorctl reload
ExecStop=/usr/local/bin/supervisorctl shutdown
User=root

[Install]
WantedBy=multi-user.target

言語ごとの設定

go用のconfigファイル用意

bash
sudo touch /etc/supervisord/conf.d/example_server.conf

設定内容

example_server.conf
[program:example_server]
command=/var/www/api/app/main # ここはフルパスで
directory=/var/www/api/app/ # 実行するディレクトリを決定してる
process_name=%(program_name)s_%(process_num)02d
autostart=true
autorestart=true
user=ec2-user
numprocs=1
redirect_stderr=true
stdout_logfile=/tmp/example_server.log

実行と永続化

bash
sudo systemctl start supervisord
sudo systemctl status supervisord
sudo systemctl enable supervisord
