    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

        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
