1、安装
安装比较简单执行一下命令即可
sudo apt-get install supervisor
2、修改配置文件
/etc/supervisor/supervisord.conf
修改配置，通过web页面可查看进程工作状态。内容如下
; supervisor config file
[unix_http_server]
file=/var/run//supervisor.sock ; (the path to the socket file)
;chmod=0700 ; sockef file mode (default 0700)
[inet_http_server] ; inet (TCP) server disabled by default
port=0.0.0.0:9001 ; (ip_address:port specifier, *:port for all iface)
username=user ; (default is no username (open server))
password=123 ; (default is no password (open server))
[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)
;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
; 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.
[include]
files = /etc/supervisor/conf.d/*.conf
3、添加进程配置文件
安装轻型http服务器
pip3 install gunicorn
gunicorn -w 4 -b 0.0.0.0:8080 flaskgunicorn:app #flaskguicorn文件名 app应用名。
在/etc/supervisor/conf.d下添加 xxx.conf即可内容如下
[program:cameraService]
directory =/home/project/CameraServer/
command =gunicorn -w 4 -b 0.0.0.0:5000 index:app
autostart = true
startsecs = 5
autorestart = true
startretries = 10
user = root
redirect_stderr = true
stdout_logfile_maxbytes = 20MB
stdout_logfile_backups = 20
stdout_logfile = /home/project/CameraServer/CameraServer.log
视频推流hls配置如下
[program:ffmpegvideo1]
directory =/home/project/CameraServer/static/video1/
command = bash -c 'sleep 20s && ffmpeg -rtsp_transport tcp -v info -i "rtsp://192.168.1.207:554/user=admin&password=&channel=1&stream=1.sdp?real_stream" -c:v copy -c:a copy -bufsize 1835k -pix_fmt yuv420p -flags -global_header -hls_time 1 -hls_list_size 6 -hls_wrap 10 -start_number 1 /home/project/CameraServer/static/video1/index.m3u8'
autostart = true
startsecs = 5
autorestart = true
startretries = 10
user = root
redirect_stderr = true
stdout_logfile_maxbytes = 20MB
stdout_logfile_backups = 20
