vim itchat.ini

新增itchat进程

[program:itchat]
directory = /var/www/itchat/application              ;启动目录
command =  python3 scwechat.py                     ;启动命令
autostart = true                                               ;在supervisord启动的时候也启动
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                                                      ;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 = 20                           ;stdout日志文件备份数
stdout_logfile = /tmp/supervisord/itchat.log 
;stdout日志文件，需要手动创建/tmp/supervisord目录

supervisorctl start itchat
