Supervisor deployment (offline deployment requires downloading the deployment package in advance)

1. Software preparation

download tar package ：wget https://pypi.python.org/packages/source/s/supervisor/supervisor-3.1.3.tar.gz

decompression ：tar -xvf supervisor-3.1.3.tar.gz

Enter the decompression package ：cd supervisor-3.1.3

Start installation ：python setup.py install

download meld3 Deployment package ：wget https://pypi.python.org/packages/source/m/meld3/meld3-1.0.2.tar.gz

decompression ：tar -xvf meld3-1.0.2.tar.gz

Enter the decompression package ：cd meld3-1.0.1.tar.gz

Start installation ：python setup.py install

2. Test and reset the configuration file

test supervisor：echo_supervisord_conf

Create directory ：mkdir /yunwei/supervisor

Enter this directory to create a subdirectory ：cd /yunwei/supervisor

  mkdir conf（ This folder is used to store supervisor The target of hosting service is supervisor Configuration file for ）

mkdir logs（ This document is for storage supervisor journal ）

mkdir pid

mkdir socket

supervisor Service hosting , You need to point to the hosting service for supervisor Configuration file for , And this document needs to be connected with supervisor The configuration file of

Get into conf Folder ：cd conf

create a file ：mkdir supervisor.d（ This folder is used to store supervisor Configuration file for ）

establish supervisor The configuration file points to supervisor.d Folder ：

echo_supervisord_conf > /yunwei/supervisor/conf/supervisor.d/supervisord.conf

start-up supervisor：

/usr/bin/python2 /usr/bin/supervisord -c /yunwei/supervisor/conf/supervisor.d/supervisord.conf

modify supervisord.conf The configuration file ：

[unix_http_server]  This configuration item is enabled http service

file Need to point to socket In file supervisor.sock file

（ Need to be in socket Create the file in the folder ：touch supervisor.sock）

[inet_http_server]  This configuration item is enabled web Page services

If there are notes , Cancel the comment , User and password can be customized

[supervisord]  The configuration item is supervisor The configuration file

logfile Need to point to logs in supervisord.log file （ This file needs to be created ）

pidfile Need to point to pid in supervisord.pid file （ You need to create a modification file ）

[supervisorctl] The configuration item is socket File configuration

serverurl Need to point to socket in supervisor.sock file （ Change the file to report missing more , Sometimes you need to create , Sometimes there is no need to create ）

[include] The configuration item is supervisor Used to configure supervisor Regulatory services Basic configuration （ By identifying the configuration file , Give Way supervisor Services are linked to regulatory services ）

files Need to point to conf All of the *.conf file

In a formal development environment , How many regulatory services are there ,conf How many corresponding configuration files are there in the file

Supervision service configuration

Here to tomcat For example

Entry directory ：cd /yunwei/supervisor/conf

create profile ：touch tomcat.conf

The new content ：

[program:tomcat]

command=/yunwei/tomcat/bin/catalina.sh run

environment=JAVA_HOME="/yunwei/jdk",JAVA_BIN="/yunwei/jdk/bin"

directory=/yunwei/tomcat

user=root

autostart = true

autorestart=true

redirect_stderr=true

stderr_logfile=/yunwei/supervisor/logs/tomcat.log/tomcat.err.log

stdout_logfile=/yunwei/supervisor/logs/tomcat.log/tomcat.out.log

[program:tomcat]： Define the name of the regulatory service

command： Define how to start the regulatory service 、 And instructions

environment： Definition tomcat Dependence

directory： Definition tomcat The path of

user： Define startup tomcat The account of

autostart： Define auto start

autorestart： Define automatic restart

redirect_stderr： hold stderr Redirect

priority=999：# Process startup priority , Default 999, If Supervisord Need to manage multiple processes , Then the low value starts first

stderr_logfile： The error log output needs to point to the log file （ If there is no need to create this file ）

stdout_logfile： The output log needs to point to the log file （ If there is no need to create this file ）

stdout_logfile_maxbytes=200MB             #stdout Standard output log file size , Log file size to 200M After that, it will be cut , The log file after cutting will be marked as catalina.out1,catalina.out2,catalina.out3..., Default 50MB

stdout_logfile_backups = 100                 #stdout Number of standard output log file backups , preservation 100 individual 200MB Log file , exceed 100 The old ones will be deleted after one , The default is 10 preservation 10 individual

stopasgroup=false                          # The default is false, When the process is killed , Send... To this process group stop The signal , Include subprocesses

killasgroup=false                           # The default is false, Send... To the process group kill The signal , Include subprocesses

startretries=3      # Number of auto retries that failed to start , The default is 3

start-up supervisor

/usr/bin/python2 /usr/bin/supervisord -c /etc/supervisord.conf（ The path needs to be replaced with supervisord.conf Otherwise, an error will be reported ）
