supervisor is a general process management program developed in Python, which can turn an ordinary command-line process into a background daemon and monitor the process status. It can automatically restart when exiting abnormally.

Install supervisor

# yum search setuptools.... python-setuptools.noarch : Easily build and distribute Python packages #yum install -y python-setuptools.noarch #easy_install supervisor

# mkdir -m 755 -p /etc/supervisor \\Create supervisor configuration file directory # echo_supervisor_conf >/etc/supervisor/supervisor.conf \\Create main configuration file # cd /etc/supervisor/# mkdir -m 755 conf.d \\Create project profile directory

Create project profile (run 3 scripts)

# vim conf.d/test.ini[program:tjapp_sendmessage]command=/bin/bash /data/shell/sendmessage.shnumprocs=1autostart=trueautorestart=true [program:bbscollection]command=/bin/bash /data/shell/bbscollection.shnumprocs=1autostart=trueautorestart=true [program:test_sbbscollection]command=/bin/bash /data/shell/test_sbbscollection.shnumprocs=1autostart=trueautorestart=true

# supervisord -c /etc/supervisord.conf
