MongoDBをsupervisorでプロセス監視する手順メモ

環境

ubuntu16.04LTS
MongoDB version v3.4.11
supervisor 3.2.0

手順

/etc/supervisor/conf.d/mongod.confを作成

/etc/supervisor/conf.d/mongod.conf

[program:mongod] ;
directory=/var/lib/mongodb ; 
command=/usr/bin/mongod -f /etc/mongod.conf ;
numprocs=1 ; 
autostart=true ; 
autorestart=true ; 
user=mongodb ; 
redirect_stderr=true ; 
stdout_logfile=/var/log/supervisor/mongod.log ;

/etc/mongod.confはデフォルトだけど一応掲載

/etc/mongod.conf

# mongod.conf

# for documentation of all options, see:
#   http://docs.mongodb.org/manual/reference/configuration-options/

# Where and how to store data.
storage:
  dbPath: /var/lib/mongodb

# where to write logging data.

  destination: file
  logAppend: true
  path: /var/log/mongodb/mongod.log

dbpathの/var/lib/mongodb 以下が全てmongodbユーザでアクセスできるか確認
なってなければ次のコマンドで所有権変更しとけばok

$ cd /var/lib
$ sudo chown -R mongodb mongodb
$ sudo chgrp -R mongodb mongodb

あとはsupervisorを起動してファイル読ませてmongod起動、起動確認

$ sudo service supervisor start
$ sudo supervisorctl reread
$ sudo supervisorctl start mongod
$ sudo supervisorctl status
mongod                           RUNNING   pid 5652, uptime 0:00:10

上手くいかなければsupervisorを再起動

$ sudo service supervisor restart
$ sudo supervisorctl status
mongod                           RUNNING   pid 5652, uptime 0:00:10

一応、

$ mongo

でmongodbに接続できるか確認
