centos supervisor 安装及常见的问题

supervisor安装
方法一、使用yum命令安装（推荐）
$ sudo su - #切换为root用户

# yum install epel-release

# yum install -y supervisor

# systemctl enable supervisord 
systemctl enable supervisord.service

# 开机自启动
# 

systemctl start supervisord 
systemctl start supervisord.service

# 查看启动supervisord服务

# systemctl status supervisord
 ps -aux|grep supervisord

 # 查看supervisord服务状态

# ps -ef|grep supervisord # 查看是否存在supervisord进程

方法一、源码安装（省事的不推荐）
https://pypi.org/project/supervisor/#files

supervisor 修改加载配置路径
vi /etc/supervisord.conf 

[include]
files = /data/supervisord.d/*.conf

/etc/supervisord.d/*.conf

spawn 在expect里面

安装expect：
yum -y install expect

centos查看防火墙:

查看防火墙状态

firewall-cmd --state

停止firewall

systemctl stop firewalld.service

开启firewall
systemctl start firewalld

禁止firewall开机启动

systemctl disable firewalld.service 

开机启动防火墙

systemctl enable firewalld

supervisor 进程配置cesi 文件例子 

[program:cesi] #程序名字不能重复

directory =/root/cesi

command=/root/cesi/venv/bin/python3 ./cesi/run.py --config-file /etc/cesi.conf 

autostart=true

autorestart=true

startsecs=3
user=root
numprocs=1
redirect_stderr=true

stdout_logfile_backups = 7 
stdout_logfile_maxbytes = 50MB  
stdout_logfile=/root/cesi/cesi_stdout.log

supervisor进程 web 管理界面cesi
---第一种安装---

参考官方REAME.md

https://github.com/gamegos/cesi

使用yarn install安装的时候，提示错误

yarn config set ignore-engines true

---第二种安装---

pip install flask

脚本安装配置cesi

vi /home/cesi.sh

cesi配置文件例子

vi /etc/cesi.conf

# This is the CeSI's own configuration.
[cesi]
# Database Uri
database = "sqlite:///users.db"                         # Relative path
# Etc
#database = "sqlite:opt/cesi/< version >/users.db"  # Absolute path
#database = "postgres://:@localhost:5432/"
#database = "mysql+pymysql://:@localhost:3306/"
activity_log = "activity.log"   # File path for CeSI logs
admin_username = "admin"        # Username of admin user
admin_password = "admin"        # Password of admin user

# This is the definition section for new supervisord node.
# [[nodes]]
# name = "api"          # (String) Unique name for supervisord node.
# environment = ""      # (String) The environment name provides logical grouping of supervisord nodes. It can be used as filtering option in the UI.
# username = ""         # (String) Username of the XML-RPC interface of supervisord Set nothing if no username is configured
# password = ""         # (String) Password of the XML-RPC interface of supervisord. Set nothing if no username is configured
# host = "127.0.0.1"    # (String) Host of the XML-RPC interface of supervisord
# port = "9001"         # (String) Port of the XML-RPC interface of supervisord

# Default supervisord nodes

[[nodes]]
name = "ecs-soms"
environment = "soms"
username = "admin"  #supervisord web 的用户名
password = "admin" #密码
host = "127.0.0.1"
port = "9001"

常用指令：
supervisord --nodaemon 前台启动Supervisor服务
supervisorctl -i 进入交互式Shell
supervisorctl status 查看任务列表
supervisorctl status helloworld 查看指定任务的状态
supervisorctl stop/start/restart all 结束/启动/重启所有任务
supervisorctl stop/start/restart helloworld 结束/启动/重启指定任务
supervisorctl reroad 重新加载配置文件，不增减任务
supervisorctl update all 重新加载配置文件，并进行必要的增减任务
supervisorctl remove/add 移除/添加任务(配置文件中已经存在的任务)
supervisorctl tail -f helloworld 实时查看任务的控制台输出
supervisorctl tail -f helloworld stderr 实时查看任务的控制台错误输出
supervisorctl reload 重启Supervisor服务
supervisorctl fg helloworld 将任务拉到前台，此时Ctrl+C不会结束任务，而是将任务放回后台
supervisorctl shutdown 终止Supervisor服务
supervisorctl clear all 清楚所有进程的日志文件
supervisorctl maintail -f 实时查看Supervisor服务的日志文件
supervisorctl signal SIGTERM all 结束所有进程
supervisorctl signal SIGKILL all 杀死所有进程
supervisorctl --serverurl http://localhost:9001 status 管理远程Supervisor服务
