如何使用主管启动 Cloud SQL 代理
How to start Cloud SQL proxy with supervisor
我试图在 supervisor 上启动 CloudSQL 代理，但我不知道它出了什么问题。 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 supervisor 并下载了 cloud_sql_proxy。我把文件放在 /root 下并以 root 身份执行以进行调试。
这是我当前的设置：
/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：
2018-10-14 15:49:49,984 INFO spawned: 'cloud_sql_proxy' with pid 3569
2018-10-14 15:49:49,989 INFO exited: cloud_sql_proxy (exit status 0; not expected)

2018-10-14 15:51:47,999 INFO gave up: cloud_sql_proxy entered FATAL state, too many start retries too quickly
最后我想出了一个可行的解决方案，就是这样：
新建文件/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，更改命令以执行 bash 文件：
command=/root/start_cloud_sql_proxy.sh
