ubuntu中supervisor的报错child process was not spawned

一、问题描述

ubuntu18.04安装supervisor。按照步骤装完，能看的到管理网页。但是一直启动不起来。

查看日志显示：

supervisor: couldn‘t chdir to /.../: ENOENT

supervisor：child process was not spawned

二、解决办法

从新写了一下 进程配置文件。进程配置文件中的 ‘‘ ; ‘ 前必须有空格号。最终的两个配置文件如下

1、supervisor配置文件

存储路径：/etc/supervisor/supervisord.conf

; Sample supervisor config file.
;
; For more information on the config file, please see:
; http://supervisord.org/configuration.html
;
; Notes:
;  - Shell expansion ("~" or "$HOME") is not supported.  Environment
;    variables can be expanded using this syntax: "%(ENV_HOME)s".
;  - Comments must have a leading space: "a=b ;comment" not "a=b;comment".

[unix_http_server]
file=/var/run/supervisor.sock   ; (the path to the socket file)
chmod=0700                 ; socket file mode (default 0700)
;chown=nobody:nogroup       ; socket file uid:gid owner
;username=user              ; (default is no username (open server))
;password=123               ; (default is no password (open server))

[inet_http_server]         ; inet (TCP) server disabled by default
port=127.0.0.1:9001        ; (ip_address:port specifier, *:port for all iface)
;username=admin              ; (default is no username (open server))
;password=123456               ; (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)
;umask=022                   ; (process file creation umask;default 022)
user=root                 ; (default is current user, required if root)
;identifier=supervisor       ; (supervisord identifier, default is ‘supervisor‘)
;directory=/tmp              ; (default is not to cd during start)
;nocleanup=true              ; (don‘t clean up tempfiles at start;default false)
childlogdir=/var/log/supervisor            ; (‘AUTO‘ child log dir, default $TEMP)
;environment=KEY="value"     ; (key value pairs to add to environment)
;strip_ansi=false            ; (strip ansi escape codes in logs; def. false)

; 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:///tmp/supervisor.sock ; use a unix:// URL  for a unix socket
serverurl=http://127.0.0.1:9001 ; use an http:// url to specify an inet socket
username=root              ; should be same as http_username if set
password=ebo123456                ; should be same as http_password if set
;prompt=mysupervisor         ; cmd line prompt (default "supervisor")
;history_file=~/.sc_history  ; use readline history if available

; The below sample eventlistener section shows all possible
; eventlistener subsection values, create one or more ‘real‘
; eventlistener: sections to be able to handle event notifications
; sent by supervisor.

; The below sample group section shows all possible group values,
; create one or more ‘real‘ group: sections to create "heterogeneous"
; process groups.

;[group:thegroupname]
;programs=progname1,progname2  ; each refers to ‘x‘ in [program:x] definitions
;priority=999                  ; the relative start priority (default 999)

; 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

2、进程配置文件

路径：/etc/supervisor/conf.d/test.conf

[program:Lpn.Park.Service.Core]
command=  dotnet  Lpn.Park.Service.Core.dll
directory=/home/ebo/lpn/lpn6
environment=ASPNETCORE__ENVIRONMENT=Production
user=root
stopsignal=INT
autostart=true
autorestart=true
startsecs=1
startretries=3
stderr_logfile=/var/log/test.err.log
stdout_logfile=/var/log/test.out.log
