# Max open files问题，修改supervisord配置

directory = /{path}/echo-web ; 程序的启动目录
command = /{path}/echo-web/echo-web -c /{path}/echo-web/conf/conf.toml ; 启动命令，与手动在命令行启动的命令是一样的
process_name=%(program_name)s ; process_name expr (default %(program_name)s)
numprocs=1 ; number of processes copies to start (def 1)
autostart = true ; 在 supervisord 启动的时候也自动启动
startsecs = 5 ; 启动 5 秒后没有异常退出，就当作已经正常启动了
autorestart = true ; 程序异常退出后自动重启
startretries = 3 ; 启动失败自动重试次数，默认是 3
user = root ; 用哪个用户启动
redirect_stderr = true ; 把 stderr 重定向到 stdout，默认 false
stdout_logfile_maxbytes = 20MB ; stdout 日志文件大小，默认 50MB
stdout_logfile_backups = 7 ; stdout 日志文件备份数
; stdout 日志文件，需要注意当指定目录不存在时无法正常启动，所以需要手动创建目录（supervisord 会自动创建日志文件）
stdout_logfile = /var/log/echo-web/stdout.log
; 这一配置项的作用是：如果supervisord管理的进程px又产生了若干子进程，使用supervisorctl停止px进程，停止信号会传播给px产生的所有子进程，确保子进程也一起停止。这一配置项对希望停止所有进程的需求是非常有用的。
