supervisor安装  
方法一、使用yum命令安装（推荐）  
$ sudo su - \#切换为root用户

\# yum install epel-release

\# yum install -y supervisor

\# systemctl enable supervisord   
systemctl enable supervisord.service

\# 开机自启动  
\#

systemctl start supervisord   
systemctl start supervisord.service

\# 查看启动supervisord服务

\# systemctl status supervisord  
 ps -aux|grep supervisord

\# 查看supervisord服务状态

\# ps -ef|grep supervisord \# 查看是否存在supervisord进程

方法一、源码安装（省事的不推荐）  
https://pypi.org/project/supervisor/\#files

supervisor 修改加载配置路径  
vi /etc/supervisord.conf

\[include\]  
files = /data/supervisord.d/\*.conf

/etc/supervisord.d/\*.conf

spawn 在expect里面

安装expect：  
yum -y install expect

centos查看防火墙:

查看防火墙状态

firewall-cmd --state

停止firewall

systemctl stop firewalld.service

开启firewall  
systemctl start firewalld

禁止firewall开机启动

systemctl disable firewalld.service

开机启动防火墙

systemctl enable firewalld

supervisor 进程配置cesi 文件例子

\[program:cesi\] \#程序名字不能重复

directory =/root/cesi

command=/root/cesi/venv/bin/python3 ./cesi/run.py --config-file /etc/cesi.conf

autostart=true

autorestart=true

startsecs=3  
user=root  
numprocs=1  
redirect\_stderr=true

stdout\_logfile\_backups = 7   
stdout\_logfile\_maxbytes = 50MB    
stdout\_logfile=/root/cesi/cesi\_stdout.log

supervisor进程 web 管理界面cesi  
\---第一种安装---

参考官方REAME.md

https://github.com/gamegos/cesi

使用yarn install安装的时候，提示错误

yarn config set ignore-engines true

\---第二种安装---

pip install flask

脚本安装配置cesi

vi /home/cesi.sh

cesi配置文件例子

vi /etc/cesi.conf

\# This is the CeSI's own configuration.  
\[cesi\]  
\# Database Uri  
database = "sqlite:///users.db"                         \# Relative path  
\# Etc  
\#database = "sqlite:opt/cesi/< version >/users.db"  \# Absolute path  
\#database = "postgres://<user>:<password>@localhost:5432/<database\_name>"  
\#database = "mysql+pymysql://<user>:<password>@localhost:3306/<database\_name>"  
activity\_log = "activity.log"   \# File path for CeSI logs  
admin\_username = "admin"        \# Username of admin user  
admin\_password = "admin"        \# Password of admin user

\# This is the definition section for new supervisord node.  
\# \[\[nodes\]\]  
\# name = "api"          \# (String) Unique name for supervisord node.  
\# environment = ""      \# (String) The environment name provides logical grouping of supervisord nodes. It can be used as filtering option in the UI.  
\# username = ""         \# (String) Username of the XML-RPC interface of supervisord Set nothing if no username is configured  
\# password = ""         \# (String) Password of the XML-RPC interface of supervisord. Set nothing if no username is configured  
\# host = "127.0.0.1"    \# (String) Host of the XML-RPC interface of supervisord  
\# port = "9001"         \# (String) Port of the XML-RPC interface of supervisord

\# Default supervisord nodes

\[\[nodes\]\]  
name = "ecs-soms"  
environment = "soms"  
username = "admin"  \#supervisord web 的用户名  
password = "admin" \#密码  
host = "127.0.0.1"  
port = "9001"

常用指令：  
supervisord --nodaemon 前台启动Supervisor服务  
supervisorctl -i 进入交互式Shell  
supervisorctl status 查看任务列表  
supervisorctl status helloworld 查看指定任务的状态  
supervisorctl stop/start/restart all 结束/启动/重启所有任务  
supervisorctl stop/start/restart helloworld 结束/启动/重启指定任务  
supervisorctl reroad 重新加载配置文件，不增减任务  
supervisorctl update all 重新加载配置文件，并进行必要的增减任务  
supervisorctl remove/add 移除/添加任务(配置文件中已经存在的任务)  
supervisorctl tail -f helloworld 实时查看任务的控制台输出  
supervisorctl tail -f helloworld stderr 实时查看任务的控制台错误输出  
supervisorctl reload 重启Supervisor服务  
supervisorctl fg helloworld 将任务拉到前台，此时Ctrl+C不会结束任务，而是将任务放回后台  
supervisorctl shutdown 终止Supervisor服务  
supervisorctl clear all 清楚所有进程的日志文件  
supervisorctl maintail -f 实时查看Supervisor服务的日志文件  
supervisorctl signal SIGTERM all 结束所有进程  
supervisorctl signal SIGKILL all 杀死所有进程  
supervisorctl --serverurl http://localhost:9001 status 管理远程Supervisor服务
