デーモン化されてないアプリをデーモン化したいときに使う。daemontools的な。

CentOS6の場合 epelが設定されてるなら

# yum -y --enablerepo=epel install supervisor

starmanの起動用スクリプトを/var/www/tools/mt/mt.shにおいていたとして。

$ vi /var/www/tools/mt/mt.sh
 
#!/bin/sh
 
cd /var/www/mt
STAR=/usr/local/bin/starman
PID=/var/www/tools/
$STAR --l :5000 --pid $PID/mt.pid ./mt.psgi

設定ファイルは/etc/supervisor.conf

# vi /etc/supervisor.conf

unicornの起動用スクリプトを/var/www/tools/redmine/redmine.sh

$ vi /var/www/tools/redmine/redmine.sh
 
#!/bin/sh                                                                                               
 
cd /var/lib/redmine                                                                                     
BUNDLE=/usr/local/rbenv/shims/bundle

CONF=config/unicorn_redmine.rb
$BUNDLE exec unicorn_rails -E $ENV -c $CONF -p 8080 

パーミッションは適宜設定。

# vi /etc/supervisor.conf
 
[program:redmine]
user=webapp                                    
command=/var/www/tools/redmine/redmine.sh

stdout_logfile=/var/log/unicorn/stdout.log        
logfile_maxbytes=1MB                         

$ sudo /etc/init.d/supervisord start

supervisorctlを使う。

$ sudo supervisorctl status # statusの確認 
$ sudo supervisorctl start mt # 個別プロセスのスタート
$ sudo supervisorctl stop mt # 個別プロセスのストップ
