我已经从 ubuntu 10.04 (64 位) 上的系统包安装了 Supervisord 3.0a8。Supervisor 服务似乎正在运行,但它没有启动配置的程序。有趣的是,这个确切的配置正在另一个系统上运行,并且按预期运行。
主配置文件如下所示:
; /etc/supervisor/supervisord.conf
[unix_http_server]
chmod=0700
file=/var/run/supervisor.sock
[supervisord]
logfile=/var/log/supervisor/supervisord.log
childlogdir=/var/log/supervisor
pidfile=/var/run/supervisord.pid
[rpcinterface:supervisor]
supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface
[supervisorctl]
serverurl=unix:///var/run/supervisor.sock
[include]
files = /etc/supervisor/conf.d/*.conf
示例程序配置如下所示:
; /etc/supervisor/conf.d/sample.conf
[program:sample]
directory=/opt/sample
command=/opt/sample/run.sh
其中,为/opt/sample/run.sh
:
#!/bin/bash
while true; do
T=`date`
echo "[$T] Running!" >> /var/log/sample.log
sleep 1
done
另外,这里还有一些有关 Supervisord 运行实例的附加信息:

任何帮助是极大的赞赏!
答案1
当我忘记时就会发生这种情况sudo supervisorctl update
。
另外,/opt/sample/run.sh 是否设置了可执行位?
答案2
我想补充一下
日志级别=调试
到 [supervisord] 部分。这可能会有所帮助。似乎 include 不起作用。supervisorctl status 应该显示你的脚本正在运行。
答案3
尝试使用 -n 选项运行,它会将调试命令直接发送到命令行。简化调试过程。
系统是否完全相同,即彼此的虚拟克隆?检查文件是否可执行,以确保万无一失,过去使用supervisord时,我曾因此受挫。
