報錯總結如下
更新apt
sudo apt update && sudo apt upgrade
pip3 install supervisor
<!--生成配置文件-->
echo_supervisord_conf > /etc/supervisord.conf
常用命令
supervisorctl status 查看狀態(tài)
supervisorctl reload 重新載入配置文件
supervisorctl start all/ftp 啟動所有/指定的程序進程
supervisorctl stop all/frp 關閉所有/指定的程序進程
簡化后的supervisord.conf配置文件內容：
[unix_http_server]
file=/run/supervisor/supervisor.sock ; (the path to the socket file)
[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=/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:///run/supervisor/supervisor.sock ; use a unix:// URL for a unix socket
[include]
files = supervisor.d/*.conf
注意 所有需要用supervisor管理的服務放在/etc/supervisor.d/目錄下；
supervisor開機自啟
1、首先執(zhí)行命令：systemctl is-enabled supervisord ，結果如下圖：提示尚未為supervisor配置開機啟動
2、在shell里執(zhí)行 vim /lib/systemd/system/supervisord.service 編輯開機啟動時執(zhí)行的腳本如下
[Unit]
Description=Process Monitoring and Control Daemon
After=rc-local.service
[Service]
Type=forking
ExecStart=/usr/bin/supervisord -c /etc/supervisord.conf
RuntimeDirectory=supervisor
RuntimeDirectoryMode=755
[Install]
WantedBy=multi-user.target
注意：ExecStart=/usr/bin/supervisord -c /etc/supervisord.conf 一定要這樣寫，supervisor安裝完默認會在/etc/supervisord.conf 產生
啟動程序
systemctl enable supervisord
驗證一下是否為開機啟動：
systemctl is-enabled supervisord
二. “supervisor.sock no such file”的解決方法
1：去/run/supervisor中touch一個supervisor.sock文件 并chmod 777 supervisor.sock
2：kill 掉所有之前的supervisor進程
3：啟動supervisor
<!--啟動-->
systemctl start supervisor
supervisord -c /etc/supervisord.conf
<!--關閉-->
systemctl stop supervisor
重新啟動supervisor
三：Error: Cannot open an HTTP server: socket.error reported errno.ENOENT (2)
supervisord -c /etc/supervisord.conf 啟動時報錯
Error: Cannot open an HTTP server: socket.error reported errno.ENOENT (2)
For help, use /usr/bin/supervisord -h
原因，默認配置的目錄不存在， 手動創(chuàng)建一個就好了mkdir /run/supervisor
