一.查看默认配置

[root@node101.yinzhengjie.org.cn ~]# egrep -v "^ *#|^$" /etc/httpd/conf/httpd.conf  
ServerRoot "/etc/httpd"
Listen 80
Include conf.modules.d/*.conf
User apache
Group apache
ServerAdmin root@localhost
<Directory />
    AllowOverride none
    Require all denied
</Directory>
DocumentRoot "/var/www/html"
<Directory "/var/www">
    AllowOverride None
    Require all granted
</Directory>
<Directory "/var/www/html">
    Options Indexes FollowSymLinks
    AllowOverride None
    Require all granted
</Directory>
<IfModule dir_module>
    DirectoryIndex index.html
</IfModule>
<Files ".ht*">
    Require all denied
</Files>
ErrorLog "logs/error_log"
LogLevel warn
<IfModule log_config_module>
    LogFormat "%h %l %u %t "%r" %>s %b "%{Referer}i" "%{User-Agent}i"" combined
    LogFormat "%h %l %u %t "%r" %>s %b" common
    <IfModule logio_module>
      LogFormat "%h %l %u %t "%r" %>s %b "%{Referer}i" "%{User-Agent}i" %I %O" combinedio
    </IfModule>
    CustomLog "logs/access_log" combined
</IfModule>
<IfModule alias_module>
    ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
</IfModule>
<Directory "/var/www/cgi-bin">
    AllowOverride None
    Options None
    Require all granted
</Directory>
<IfModule mime_module>
    TypesConfig /etc/mime.types
    AddType application/x-compress .Z
    AddType application/x-gzip .gz .tgz
    AddType text/html .shtml
    AddOutputFilter INCLUDES .shtml
</IfModule>
AddDefaultCharset UTF-8
<IfModule mime_magic_module>
    MIMEMagicFile conf/magic
</IfModule>
EnableSendfile on
IncludeOptional conf.d/*.conf
[root@node101.yinzhengjie.org.cn ~]# 

二.修改监听的IP和Port语法

Listen [IP:]PORT
　　(1)省略IP表示为本机所有IP
　　(2)Listen指令至少一个，可重复出现多次

三.修改监听的IP地址和Port实战案例

[root@node101.yinzhengjie.org.cn ~]# ss -ntl 　　　　　　　　#默认监听本机的所有IP地址的80端口
State       Recv-Q Send-Q        Local Address:Port                       Peer Address:Port              
LISTEN      0      128                       *:80                                    *:*                  
LISTEN      0      128                       *:22                                    *:*                  
LISTEN      0      128                      :::22                                   :::*                  
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# vim /etc/httpd/conf.d/listen.conf
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# cat /etc/httpd/conf.d/listen.conf　　　　　　#我们可以配置多条listen指令，它们并不会相互影响哟~
listen 8080
listen 172.30.1.101:8090
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# httpd -t
Syntax OK
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# systemctl reload httpd
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# ss -ntl 
State       Recv-Q Send-Q        Local Address:Port                       Peer Address:Port              
LISTEN      0      128                       *:8080                                  *:*                  
LISTEN      0      128                       *:80                                    *:*                  
LISTEN      0      128                       *:22                                    *:*                  
LISTEN      0      128            172.30.1.101:8090                                  *:*                  
LISTEN      0      128                      :::22                                   :::*
