【问题描述】：

我尝试在supervisor 上启动 CloudSQL 代理，但我不知道它有什么问题。 The documentation 没有显示此问题的任何线索。任何想法将不胜感激。

我在干净的 Ubuntu 16 上尝试了设置，然后安装了主管并下载了 cloud_sql_proxy。我将文件放在/root 下并以root 身份执行以进行调试。

这是我目前的设置：

/etc/supervisord.conf

[unix_http_server]
file=/tmp/supervisor.sock   ; the path to the socket file
chmod=0766                  ; socket file mode (default 0700)

[supervisord]
logfile=/tmp/supervisord.log ; main log file; default $CWD/supervisord.log
logfile_maxbytes=50MB        ; max main logfile bytes b4 rotation; default 50MB
logfile_backups=10           ; # of main logfile backups; 0 means none, default 10
loglevel=info                ; log level; default info; others: debug,warn,trace
pidfile=/tmp/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:///tmp/supervisor.sock ; use a unix:// URL  for a unix socket

[include]
files = /etc/supervisor/conf.d/*.conf

/etc/supervisor/conf.d/cloud_sql_proxy.conf

[program:cloud_sql_proxy]
command=/root/cloud_sql_proxy -dir=/cloudsql -instances="project_id:us-central1:instance-name" -credential_file="/root/service-account.json"
autostart=true
autorestart=true
startretries=1
startsecs=8
stdout_logfile=/var/log/cloud_sql_proxy-stdout.log
stderr_logfile=/var/log/cloud_sql_proxy-stderr.log

检查/tmp/supervisord.log后出现以下错误：

【解决方案1】：

我终于想出了一个可行的解决方案，就是这样：

创建一个新文件/root/start_cloud_sql_proxy.sh：

#!/bin/bash
/root/cloud_sql_proxy -dir=/cloudsql -instances="project_id:us-central1:instance-name" -credential_file="/root/service-account.json"

在 /etc/supervisor/conf.d/cloud_sql_proxy.conf 下，更改执行 bash 文件的命令：

command=/root/start_cloud_sql_proxy.sh
