无法绑定到地址，没有可用的监听套接字

RockyLinux 9. 重启时 Apache 无法启动，并显示以下消息

Jul 21 10:53:13 cl httpd[877]: (99)Cannot assign requested address: AH00072: make_sock: could not bind to address 1.2.3.4:80
Jul 21 10:53:13 cl httpd[877]: no listening sockets available, shutting down
Jul 21 10:53:13 cl httpd[877]: AH00015: Unable to open logs
Jul 21 10:53:13 cl systemd[1]: httpd.service: Main process exited, code=exited, status=1/FAILURE
Jul 21 10:53:13 cl systemd[1]: httpd.service: Failed with result 'exit-code'.
Jul 21 10:53:13 cl systemd[1]: Failed to start The Apache HTTP Server.

主配置文件将其设置为监听该地址和 80 端口。但该地址的 80 和 443 端口上都有虚拟主机

如果我手动启动它，它会开始使用该地址，但 443 端口

# systemctl start httpd
Jul 21 10:55:44 cl systemd[1]: Starting The Apache HTTP Server...
Jul 21 10:55:44 cl httpd[2135]: [Fri Jul 21 10:55:44.803045 2023] [so:warn] [pid 2135:tid 2135] AH01574: module wsgi_module is already loaded, skipping

Jul 21 10:55:44 cl systemd[1]: Started The Apache HTTP Server.

有任何想法吗？

我的解决方案是覆盖/usr/lib/systemd/system/httpd.service：

# systemctl edit httpd

添加network-online.target到After：

### Editing /etc/systemd/system/httpd.service.d/override.conf
### Anything between here and the comment below will become the new contents of the file

[Unit]
After=network.target network-online.target remote-fs.target nss-lookup.target httpd-init.service

### Lines below this comment will be discarded
