thinkphp Swoole 8686 Operation not permitted

在使用supervisord服务时，如果是把thinkphp swoole先添加启动配置文件/etc/supervisord.d/mySwoole.ini：

[program:sw_mi]
command=php think swoole restart
directory=/var/www/mi/
autorestart=true
startsecs=3
startretries=3
stdout_logfile=/var/log/wwwSwoole/sw_mi.out.log
stderr_logfile=/var/log/wwwSwoole/sw_mi.err.log
stdout_logfile_maxbytes=2MB
stderr_logfile_maxbytes=2MB
user=mi
priority=999
numprocs=1
process_name=%(program_name)s_%(process_num)02d

[program:th_mi]
command=php think queue:listen --tries=2
directory=/var/www/mi/
autorestart=true
startsecs=3
startretries=3
stdout_logfile=/var/log/wwwSwoole/th_mi.out.log
stderr_logfile=/var/log/wwwSwoole/th_mi.err.log
stdout_logfile_maxbytes=2MB
stderr_logfile_maxbytes=2MB
user=mi
priority=999
numprocs=1
process_name=%(program_name)s_%(process_num)02d

然后手动启动程序时，会出现：

Swoole 8686 Operation not permitted

这样的奇怪错误，解决办法是停止supervisord服务

systemctl stop supervisord

然后就可以手动启动swoole了，测试好之后，就可以重启服务了

systemctl start supervisord
