Centos7安装Cesi（Supervisor集中管理工具）

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

2、安装依赖

shell 复制代码

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

shell 复制代码

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/

systemctl enable cesi

5、启动CeSi

shell 复制代码

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
