1. Installing the Python automation tool #yum install Python-setuptools

2. #easy_install Supervisor Installation Supervisor

3. Test whether the installation was successful #echo_supervisord_conf

4. Create the configuration file:

(1) Create Supervisor profile Directory/etc/supervisor/

#mkdir-M 755-p/etc/supervisor/

(2) Create a master file supervisord.conf

#echo_supervisord_conf >/etc/supervisor/supervisord.conf

(3) Create a project configuration file directory

# mkdir-m 755 CONF.D

5. Add a test profile to the profile directory

7. #supervisorctl-C/etc/supervisor/supervisord.conf into the supervisor management

Status View state

Stop all Stop

Reload Restart monitoring Service

Attention:

(1) Each time you modify the configuration file , you need to enter Supervisorctl, execute reload, change the part to take effect

(2) Two commands

Supervisord:supervisor server-side section for supervisor startup

Supervisorctl: Launches the command-line window for supervisor, which performs actions such as Start, stop, status, reload, and so on in the command line.

Second, Supervisord startup script

1. Execute the following command:

Vim/etc/init.d/supervisord

2. Enter the following:

#!/bin/bash## Supervisord This scripts turns supervisord on# chkconfig:345 04# description:supervisor is a process  Control Utility.

Note: the following variables in the file need to be rewritten according to your actual directory.

prefix=/usrsupervisord= $PREFIX/bin/supervisord      # #supervisord   program installation path supervisorctl= $PREFIX/bin/ Supervisorctl  # #supervisorctl Program installation path Pidfile=/var/supervisor/supervisord.pid   # #需要先创建/var/ Supervisor Directory Lockfile=/var/supervisor/supervisord.lockoptions= "-c/etc/supervisor/supervisord.conf"   # # Path to the configuration file

After saving, you can modify the file permissions by executing the following command:

chmod 777/etc/init.d/supervisord/etc/init.d/supervisord  Start or service Supervisord start

So supervisor started it.

3. Configure Boot Boot

Execute the following command:

Chkconfig Supervisord on  

You can see whether the following command is successful

Chkconfig--list | grep  Supervisord
