supervisor

1，下载地址：https://pypi.org/project/supervisor/#files

一、安装

• 源码安装

先下载最新的supervisor安装包：https://pypi.python.org/pypi/supervisor ， 如：

（python3命令为 pip install git+https://github.com/Supervisor/supervisor@master）

1. cd /usr/local/src
2. wget https://pypi.python.org/packages/7b/17/88adf8cb25f80e2bc0d18e094fcd7ab300632ea00b601cbbbb84c2419eae/supervisor-3.3.2.tar.gz
3. tar -zxvf supervisor-3.3.2.tar.gz
4. cd supervisor-3.3.2
5. python setup.py install #本地python版本为python2.7
6. # python2.7 setup.py install #本地python版本为python3以上

二、配置

1.生成配置文件

1. echo_supervisord_conf > /etc/supervisord.conf

2.启动

supervisord -c /etc/supervisord.conf

查看 supervisord 是否在运行：

ps aux | grep supervisord

3.配置

打开配置文件

vim /etc/supervisord.conf

在最下边加入

[program:sougou]   #souogu 为程序的名称
command=scrapy crawl sougou #需要执行的命令
directory=/home/mzj/桌面/sougou/sougou/wechat_name/wechat_name/spiders  #命令执行的目录
environment=ASPNETCORE__ENVIRONMENT=Production #环境变量
user=root #用户
stopsignal=INT
autostart=true #是否自启动
autorestart=true #是否自动重启
startsecs=3 #自动重启时间间隔（s）
stderr_logfile=/home/mzj/桌面/sougou/sougou/wechat_name/wechat_name/spiders/ossoffical.err.log #错误日志文件
stdout_logfile=/home/mzj/桌面/sougou/sougou/wechat_name/wechat_name/spiders/ossoffical.out.log #输出日志文件

如报错：

Unlinking stale socket /tmp/supervisor.sock

unlink /tmp/supervisor.sock

在配置文件底部，配置include

1. [include]
2. files=/etc/supervisor/*.conf #若你本地无/etc/supervisor目录，请自建

用supervisor管理进程，配置如下：

1. cd /etc/supervisor
2. vim ossfs.conf # 这里的文件名称自定义

加入以下内容：

1. ; 设置进程的名称，使用 supervisorctl 来管理进程时需要使用该进程名
2. [program:your_program_name]
3. command=python server.py --port=9000
4. ;numprocs=1 ; 默认为1
5. ;process_name=%(program_name)s ; 默认为 %(program_name)s，即 [program:x] 中的 x
6. directory=/home/python/tornado_server ; 执行 command 之前，先切换到工作目录
7. user=oxygen ; 使用 oxygen 用户来启动该进程
8. ; 程序崩溃时自动重启，重启次数是有限制的，默认为3次
9. autorestart=true
10. redirect_stderr=true ; 重定向输出的日志
11. stdout_logfile = /var/log/supervisord/tornado_server.log
12. loglevel=info

这里是启动要配置的参数，请根据自己的项目自定义添加

更改了supervisor配置文件，需要重启,运行以下指令：

supervisorctl reload

4.supervisorctl的用法

1. supervisord : 启动supervisor
2. supervisorctl reload :修改完配置文件后重新启动supervisor
3. supervisorctl status :查看supervisor监管的进程状态
4. supervisorctl start 进程名 ：启动XXX进程
5. supervisorctl stop 进程名 ：停止XXX进程
6. supervisorctl stop all：停止全部进程，注：start、restart、stop都不会载入最新的配置文件。
7. supervisorctl update：根据最新的配置文件，启动新配置或有改动的进程，配置没有改动的进程不会受影响而重启

5.若不使用控制台来管理进程，用浏览器来管理，该如何配置？

打开配置文件

vim /etc/supervisord.conf

配置 inet_http_server

1. [inet_http_server]
2. port=127.0.0.1:9001 ; 服务器ip
3. username=xxx ;自定义
4. password=xxx ;自定义

三、设置开机启动

vim /etc/init.d/supervisord

添加以下脚本

1. #! /bin/sh
2. ### BEGIN INIT INFO
3. # Provides: supervisord
4. # Required-Start: $remote_fs
5. # Required-Stop: $remote_fs
6. # Default-Start: 2 3 4 5
