Centos7安装Cesi（Supervisor集中管理工具）

本文主要是介绍Centos7安装Cesi（Supervisor集中管理工具），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

Background

• CeSi 是 Supervisor 官方推荐的集中化管理 Supervisor 实例的 Web UI，该工具是用 Python 编写，基于 Flask Web 框架 。
• Superviosr 自带的 Web UI 不支持跨机器管理Supervisor 进程，功能比较简单，通过 CeSi 可以集中管理各个服务器节点的进程，在 Web 界面就可以轻松管理各个服务的启动、关闭、重启等，方便使用。
• 当前部署环境：CentOS7.9、Python3.7.8

1、部署环境

item	version
Centos	7.9
Python	3.7.8
Flask	2.2.5
Flask-SQLAlchemy	2.5.1
psycopg2-binary	2.8.5
PyMySQL	0.9.3
SQLAlchemy	1.4.48
CeSi	2.7.1

Supervisor官方文档地址：http://supervisord.org/plugins.html#dashboards-and-tools-for-multiple-supervisor-instances
Cesi git地址：https://github.com/gamegos/cesi

2、安装依赖

yum install -y git wget epel-release npm bzip2
curl --silent --location https://dl.yarnpkg.com/rpm/yarn.repo | tee /etc/yum.repos.d/yarn.repo
yum install -y yarn

3、部署CeSi

cd /opt/
wget https://github.com/gamegos/cesi/releases/download/v2.7.1/cesi-extended.tar.gz
cd cesi/
pip3 install -r requirements.txt
cd /opt/cesi/ui/
yarn install
yarn build

4、配置CeSi

• 创建日志目录

mkdir -p /opt/cesi/logs/

• /etc/cesi.conf.toml

# 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 = "/opt/cesi/logs/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 = "elephant"
environment = "dev"
username = "admin"
password = "admin"
host = "elephant"
port = "9001"[[nodes]]
name = "test"
environment = "test"
username = "admin"
password = "admin"
host = "test"
port = "9001"[[nodes]]
name = "app"
environment = "prod"
username = "admin"
password = "admin"
host = "app"
port = "9001"[[nodes]]
name = "app01"
environment = "prod"
username = "admin"
password = "admin"
host = "app01"
port = "9001"

• /etc/systemd/system/cesi.service

[Unit]
Description=cesi[Service]
Environment=
ExecStart=/usr/bin/python3 /opt/cesi/cesi/run.py --config-file /etc/cesi.conf.toml
ExecReload=/bin/kill -HUP $MAINPID
KillSignal=TERM
User=root
WorkingDirectory=/opt/cesiRestart=on-failure[Install]
WantedBy=multi-user.target

• 配置系统管理

systemctl daemon-reload
systemctl enable cesi

5、启动CeSi

systemctl start cesi
# 启动正常查看信息无报错，有报错根据报错信息排查解决
systemctl status cesi

6、访问CeSi

• 浏览器访问 http://IP:5000
• 默认用户名/密码：admin/admin
• 注意：默认用户名密码不要改，改了进不去，我在这里踩坑了
