supervisor集群管理

Cesi介绍

      CeSi(Centralized Supervisor Interface) 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

Cesi安装步骤

     export CESI_SETUP_PATH=~/cesi
    mkdir ${CESI_SETUP_PATH}
    cd ${CESI_SETUP_PATH}
    wget https://github.com/gamegos/cesi/releases/download/v2.6.7/cesi-extended.tar.gz -O cesi.tar.gz
    tar -xvf cesi.tar.gz
    python3 -m venv venv
    source venv/bin/activate
    pip3 install -r requirements.txt
    pip3 install --upgrade pip
    pip install -r requirements.txt
    python3 ${CESI_SETUP_PATH}/cesi/run.py --config-file ${CESI_SETUP_PATH}/defaults/cesi.conf.toml
    pip3 install --upgrade sqlalchemy==1.3.23
    python3 ${CESI_SETUP_PATH}/cesi/run.py --config-file ${CESI_SETUP_PATH}/defaults/cesi.conf.toml

cesi.conf.toml配置

安装完成后打开web页面第一次登录报错

       

      

 Cesi正常管理

      

       

     可以远程操作已经连接上主机上的supervisor

     

      成功远程启停服务

ansible批量安装supervisor服务

     ansible通过源码包安装并自动注册成service,然后ansible就可以通过service模块来对安装好的服务进行操作
