- 這是第一個問題
1.問題過程
ab 測試的時候出現的問題
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.
解決方法:
[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

看上邊信息Nginx算是啟動了 但是有個Failed,嘗試訪問服務也沒問題，不過還是的解決這個Failed
網上查資料 又是一頓操作：
[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 是沒有什么問題，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進行測試 OK 沒問題
