Nginx 碰到的问题

• 这是第一个问题

1.问题过程

ab 测试的时候出现的问题

Benchmarking 39.105.12.8 (be patient)...apr_socket_recv: Connection refused (111)

然后

[root@smoker-linux conf.d]# systemctl reload nginx.service
Job for nginx.service invalid.

解决方法:

[root@smoker-linux conf.d]# sudo systemctl enable nginx.service
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.
[root@smoker-linux conf.d]# sudo systemctl start nginx.service
[root@smoker-linux conf.d]# systemctl status nginx.service

看上边信息Nginx算是启动了 但是有个Failed,尝试访问服务也没问题，不过还是的解决这个Failed
网上查资料 又是一顿操作：
[root@smoker-linux conf.d]# mkdir -p /etc/systemd/system/nginx.service.d 
[root@smoker-linux conf.d]# printf "[Service]\nExecStartPost=/bin/sleep 0.1\n" > /etc/systemd/system/nginx.service.d/override.conf 
[root@smoker-linux conf.d]# systemctl daemon-reload 
[root@smoker-linux conf.d]# systemctl restart nginx.service
[root@smoker-linux conf.d]#  systemctl status nginx.service

如上查看 是没有什么问题，查看Nginx PID
[root@smoker-linux conf.d]# ps -ef|grep nginx
root      2210     1  0 11:57 ?        00:00:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
nginx     2212  2210  0 11:57 ?        00:00:00 nginx: worker process
root      2237  2043  0 12:02 pts/0    00:00:00 grep --color=auto nginx

在使用ab进行测试 OK 没问题
