环境：centos7+php+mysql+openresty，目前测试 systemctl status openresty ,systemctl status php-fpm,systemctl status mysql 都 active，正常的状态。
目前：
ps -ef | grep php-fpm

access_by_lua_file "/usr/local/openresty/nginx/conf/waf/access.lua"; 放在 http 底下会不会有问题？你的 waf 看着像 httpguard
建议把 nginx 杀掉再启动看看 |

kmdd33 OP @0312birdzhang systemctl status openresty 正常啊现在

@kmdd33 listen 127.0.0.1:80? 你是在这台服务器上 curl http://127.0.0.1 出现 502 ？

kmdd33 OP 同意谢谢各位。在 stackoverflow 上面找到了答案：
解决步骤： 1.在 nginx.conf 中把 error_log and pid 前面的注释去掉。 就像这样，方便得出正确的 error.log user root; worker_processes 1; #error_log logs/error.log; error_log logs/error.log debug; #error_log logs/error.log info; pid logs/nginx.pid; 2.http{}里面的 80 端口正确配置方式是： listen 80; listen [::]:80 default_server; 3.检查哪个 pid 占用了 80 端口：809 这个进程占用了 80 端口 # sudo netstat -tulpn | grep --color :80 tcp 0 0 127.0.0.1:80 0.0.0.0:* LISTEN 809/nginx: master p [root@li1382-238 ~]# sudo kill -2 809 （这个命令很重要） [root@li1382-238 ~]# sudo netstat -tulpn | grep --color :80 [root@li1382-238 ~]# openresty [root@li1382-238 ~]# openresty -t # netstat -antp 这个命令也可以查出来哪个端口占用了 80 端口。 然后重启：openresty |
