一、Supervisor简介

supervisor是一个Linux/Unix系统上的进程监控工具，supervisor是一个Python开发的通用的进程管理程序，可以管理和监控Linux上面的进程，能将一个普通的命令行进程变为后台daemon，并监控进程状态，异常退出时能自动重启。不过同daemontools一样，它不能监控daemon进程
    
    1. yum安装supervisor
    
        yum install -y epel-release supervisor 
    
    2. 生成配置文件
    
        echo_supervisord_conf > /etc/supervisord.conf
    
    3. 编辑配置文件
    ```
        [unix_http_server]
    file=/var/run/supervisor/supervisor.sock   ; (the path to the socket file)
    [inet_http_server]         ; inet (TCP) server disabled by default
    port=*:9001        ; (ip_address:port specifier, *:port for all iface)
    [supervisord]
    logfile=/var/log/supervisor/supervisord.log  ; (main log file;default $CWD/supervisord.log)
    logfile_maxbytes=50MB       ; (max main logfile bytes b4 rotation;default 50MB)
    logfile_backups=10          ; (num of main logfile rotation backups;default 10)
    loglevel=info               ; (log level;default info; others: debug,warn,trace)
    pidfile=/var/run/supervisord.pid ; (supervisord pidfile;default supervisord.pid)
    nodaemon=false              ; (start in foreground if true;default false)
    minfds=1024                 ; (min. avail startup file descriptors;default 1024)
    minprocs=200                ; (min. avail process descriptors;default 200)
    [rpcinterface:supervisor]
    supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
    [supervisorctl]
    serverurl=unix:///var/run/supervisor/supervisor.sock ; use a unix:// URL  for a unix socket
    [include]
    files = /etc/supervisord.d/*.conf                    ; 注意写绝对路径
    ```
    4. 启动supervisord，设置开机启动
    
        supervisord -c /etc/supervisord.conf
    
        echo "supervisord -c /etc/supervisord.conf" >> /etc/rc.local
        chmod +x /etc/rc.d/rc.local
    
    5. 访问supervisor的web界面
    
        http://ip:9001
    
    6. 添加管理进程的配置文件，存放在/etc/supervisord.d/ 
    ```
        [program:elasticsearch]
    command = /usr/local/elasticsearch/bin/elasticsearch            ; 程序的启动目录
    user=elk                               ; 使用什么用户启动
    priority=10                            ; 优先级,默认999 数字越小优先级越高
    numprocs=1                             ; 启动几个进程
    autostart=true                         ; 随着supervisord的启动而启动
    autorestart=true                       ; 异常退出后,自动重启
    startrestries=3                        ; 启动失败时的最多重试次数
    redirect_stderr=true                   ; 重定向stderr到stdout
    stdout_logfile_maxbytes = 20MB         ; stdout 日志文件大小，默认 50MB
    stdout_logfile_backups = 10            ; stdout 日志文件备份数
    stdout_logfile = /home/logs/supervisor/elasticsearch_stdout.log   ; 日志文件
    ```

二、Cesi 简介
    
    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，很方便使用。
    
    1. 安装依赖
    
        yum install -y git wget epel-release python34 python34-pip npm bzip2
    
        npm install -g n (升级node到最新版)
        n latest
        curl --silent --location https://dl.yarnpkg.com/rpm/yarn.repo | sudo tee /etc/yum.repos.d/yarn.repo
        yum install -y yarn (安装yarn)
    
    2. 安装cesi （参考官网教程）
    ```
        export CESI_SETUP_PATH=/opt/cesi

mkdir $\{CESI\_SETUP\_PATH\}  
cd $\{CESI\_SETUP\_PATH\}  
wget [https://github.com/gamegos/cesi/releases/download/v2.6.7/cesi-extended.tar.gz][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  
deactivate  
cd $\{CESI\_SETUP\_PATH\}/cesi/ui  
yarn install  
yarn build

# 注意修改/etc/cesi.conf.toml 和 /etc/systemd/system/cesi.service #
