server - 数百个 /usr/sbin/apache2 -k start 进程是否会从端口 80 到 3000 杀死我的站点代理？
问题描述
抱歉，我是服务器管理新手。每当我“systemctl restart apache2”时，/usr/sbin/apache2 -k start 进程会立即填满数百个。似乎发生这种情况后，我的网络应用程序（端口 3000）的原始 ipaddress（端口 80）代理不再起作用。但是，我始终可以毫无问题地直接连接到我的 ipaddress:3000。想知道这些进程是否在干扰代理，因为它们达到 :80。还是我在 /etc/apache2/sites-available/000-default.conf 文件中错误地设置了代理？
<VirtualHost *:80>
# The ServerName directive sets the request scheme, hostname and port that
# the server uses to identify itself. This is used when creating
# redirection URLs. In the context of virtual hosts, the ServerName
# specifies what hostname must appear in the request's Host: header to
# match this virtual host. For the default virtual host (this file) this
# value is not decisive as it is used as a last resort host regardless.
# However, you must set it for any further virtual host explicitly.

# Available loglevels: trace8, ..., trace1, debug, info, notice, warn,

# It is also possible to configure the loglevel for particular

#LogLevel info ssl:warn

# For most configuration files from conf-available/, which are
# enabled or disabled at a global level, it is possible to
# include a line for only one particular virtual host. For example the
# following line enables the CGI configuration for this host only
# after it has been globally disabled with "a2disconf".
#Include conf-available/serve-cgi-bin.conf
