superisor服务安装

  1. 安装
    sudo apt install supervisor
  2. 服务启动
    • 启动：systemctl start supervisor
    • 停用：systemctl stop supervisor
    • 状态：systemctl status supervisor
    • 开机启动：systemctl enable supervisor
    • 重载：systemctl reload supervisor

  3. 服务命令
    查看当前运行的进程列表：supervisorctl status

    其他命令：
    update 更新新的配置到supervisord（不会重启原来已运行的程序）
    reload，载入所有配置文件，并按新的配置启动、管理所有进程（会重启原来已运行的程序）
    start xxx: 启动某个进程
    restart xxx: 重启某个进程
    stop xxx: 停止某一个进程(xxx)，xxx为[program:theprogramname]里配置的值
    stop groupworker: 重启所有属于名为groupworker这个分组的进程(start,restart同理)
    stop all，停止全部进程，注：start、restart、stop都不会载入最新的配置文
    reread，当一个服务由自动启动修改为手动启动时执行一下就ok

    带账户验证：supervisorctl -u admin -p Transfar@123 restart xxx

  4. 服务配置

    • supervisor参考配置（/etc/supervisor/supervisord.conf） 
      
; supervisor config file

    [unix_http_server] file=/var/run/supervisor.sock ; (the path to the socket file) chmod=0700 ; sockef file mode (default 0700)

    [supervisord] logfile=/var/log/supervisor/supervisord.log ; (main log file;default $CWD/supervisord.log) pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid) childlogdir=/var/log/supervisor ; ('AUTO' child log dir, default $TEMP)

    ; the below section must remain in the config file for RPC ; (supervisorctl/web interface) to work, additional interfaces may be ; added by defining them in separate rpcinterface: sections [rpcinterface:supervisor] supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

    [supervisorctl] serverurl=unix:///var/run/supervisor.sock ; use a unix:// URL for a unix socket ;serverurl=http://127.0.0.1:9001 ; The [include] section can just contain the "files" setting. This ; setting can list multiple files (separated by whitespace or ; newlines). It can also contain wildcards. The filenames are ; interpreted as relative to this file. Included files cannot ; include files themselves.

    [inet_http_server] ;cpu等资源占用高，可注释掉web功能 port=9001 username=
    password=

    [include] files = /etc/supervisor/conf.d/*.conf

    - 添加服务参考配置（/etc/supervisor/conf.d/**.conf）

; stdout 日志文件，需要注意当指定目录不存在时无法正常启动，所以需要手动创建目录（supervisord 会自动创建日志文件）

superisor集群管理ceshi工具安装

准备工作

  1. 安装yarn 
    sudo apt remove cmdtest
sudo apt remove yarn
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudo apt-key add -
echo "deb https://dl.yarnpkg.com/debian/ stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt-get update
sudo apt-get install yarn
  2. 依赖安装 
    sudo apt install -y git python3 python3-pip python3-venv
  3. 服务下载
    • 方式一：下载压缩包 
      wget https://github.com/gamegos/cesi/releases/download/v2.7.1/cesi-extended.tar.gz -O cesi.tar.gz
tar -xvf cesi.tar.gz
    • 方式二：git拉取 
      git clone https://github.com/gamegos/cesi.git
git checkout v2.7.1

      开始安装

    • 创建venv虚拟环境
      python3 -m venv venv
  • 激活venv虚拟环境
    source venv/bin/activate
  • 在venv虚拟环境中，使用pip3管道安装依赖
    pip3 install -r requirements.txt
  • 失效venv虚拟环境
    deactivate
  • 编译 
    cd cesi/ui
yarn install
yarn build

  • 复制配置文件到/etc目录
    cp defaults/cesi.conf.toml /etc/cesi.conf

  • 复制服务配置文件到/etc/systemd/system目录，并注册为服务 
    cp defaults/cesi.service /etc/systemd/system/cesi.service
systemctl daemon-reload #服务生效

    管理界面

  • 地址：http://127.0.0.1:5000
  • 默认账户：admin/admin
