supervisor 管理进程 基本用法

1. 我们使用brew管理,先搜索一下确认是否有我们需要的软件包

# davis @ XiaoWeis-MacBook-Pro in ~ [16:48:42]
$ brew search supervisor
==> Formulae
supervisor ✔                homebrew/linuxbrew-core/supervisor

　　

2. 执行安装

brew install supervisor

　　

3. 启动程序

brew services start supervisor

　　

4. ps 查看进程是否启动成功

# davis @ XiaoWeis-MacBook-Pro in ~ [16:56:33]
$ ps aux|grep supervisor
davis            12015   0.0  0.1  4309560   7560   ??  S     3:19PM   0:02.06 /usr/local/Cellar/supervisor/3.3.4/libexec/bin/python2.7 /usr/local/opt/supervisor/bin/supervisord -c /usr/local/etc/supervisord.ini --nodaemon
davis            16638   0.0  0.0  4268020    780 s000  S+    4:57PM   0:00.00 grep --color=auto --exclude-dir=.bzr --exclude-dir=CVS --exclude-dir=.git --exclude-dir=.hg --exclude-dir=.svn supervisor

　　

5. supervisord.ini 配置

/usr/local/etc/supervisord.ini

　　配置文件末尾有一个载入配置的路径

[include]
files = /usr/local/etc/supervisor.d/*.ini

　　然后我们新建一个supervisor.d目录

mkdir supervisor.d

　　然后我们进入到这个目录中,新建一个xxx.ini文件,就可以写我们自己的配置了,就像nginx server目录下一样的道理

6.配置项,参数详情:https://blog.51cto.com/lixcto/1539136

[program:weatherApi]
directory = /Users/davis/python_prduction/weather
command = /usr/local/bin/python3.7 /Users/davis/python_prduction/weather/index.py
autostart = true
startsecs = 3
autorestart = true
startretries = 3
user = davis
redirect_stderr = true
stdout_logfile_backups = 20
stdout_logfile=/Users/davis/logs/weather_api_success.log
stdout_logfile_maxbytes=10MB

　　然后保存退出,/usr/local/etc,退到这个路径

# davis @ XiaoWeis-MacBook-Pro in /usr/local/etc [17:22:45]
$ supervisorctl -c supervisord.ini
