有没有办法解决 CENTOS 中 nginx 状态 Active: inactive (dead) 的问题

Question

这是检查 nginx 状态时带来的结果

\n\n

[root@ttproxyapp conf.d]# service nginx status\nRedirecting to /bin/systemctl status nginx.service\n\xe2\x97\x8f nginx.service - nginx - high performance web server\n   Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; vendor preset: disabled)\n   Active: inactive (dead)\n

\n

Answer 1

sudo systemctl stop apache2
sudo systemctl start nginx

应该可以工作，因为看起来端口正在使用中（可能与 apache 一起使用）

Answer 2

看起来你的 NGINX 确实没有运行。nginx -s reload如果有一个正在运行的实例并且因此有一个 PID 文件，那么它就可以工作。

请检查以下命令的结果。

\n\n

[root@localhost conf.d]# sudo ps -elf | grep nginx\n

\n\n

应该是这样的

\n\n

1 S root      88262      1  0  80   0 - 13143 sigsus 23:47 ?        00:00:00 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf\n5 S nginx     88263  88262  0  80   0 - 13257 ep_pol 23:47 ?        00:00:00 nginx: worker process\n0 R root      88265  69227  0  80   0 - 28178 -      23:47 pts/1    00:00:00 grep --color=auto nginx\n

\n\n

你至少需要！主进程和工作进程！如果没有进程，请输入以下命令启动您的实例

\n\n

sudo /bin/systemctl start nginx.service或者sudo service nginx start

\n\n

运行命令后检查您的进程列表。

\n\n

启动 NGINX 服务后，应该有位于 \n 的 PID 文件/var/run/nginx.pid，并且sudo systemctl status nginx.service应该打印出类似的内容

我正在运行 NGINX Plus，但在这种情况下并不重要。
