【bug】Linux系统设置Nginx开机自动启动失败

启动失败，查看状态（systemctl status nginx.service）如下：

查看状态

看出来了，/usr/lib/systemd/system/nginx.service 配置不对：

贴下/usr/lib/systemd/system/nginx.service 的正确配置：

[Unit]
Description=The nginx HTTP and reverse proxy server
After=network.target remote-fs.target nss-lookup.target

 

[Service]
Type=forking
PIDFile=/server/nginx/logs/nginx.pid
# Nginx will fail to start if /run/nginx.pid already exists but has the wrong
# SELinux context. This might happen when running `nginx -t` from the cmdline.
# https://bugzilla.redhat.com/show_bug.cgi?id=1268621
# ExecStartPre=/usr/bin/rm -f /server/nginx/logs/nginx.pid
ExecStartPre=/server/nginx/sbin/nginx -t
ExecStart=/server/nginx/sbin/nginx -c /server/nginx/conf/nginx.conf
ExecReload=/bin/kill -s HUP $MAINPID
KillSignal=SIGQUIT
TimeoutStopSec=5
KillMode=mixed
PrivateTmp=true

[Install]
WantedBy=multi-user.target
 

相关的命令：

打开目录查看相关的配置：

vim /usr/lib/systemd/system/nginx.service

修改了配置后让该文件生效

systemctl enable nginx.service

相关的命令

systemctl start nginx.service    启动nginx
systemctl stop nginx.service    结束nginx
systemctl restart nginx.service    重启nginx

上面的启动失败的的话查看一下原因：

systemctl status nginx.service

主要看nginx.service 是否正确

能正常启动的话说明OK了。可以点击重启试试
