Apache 配置虚拟主机之2
[*]基于 name-based
[*]基于 IP
[*]基于 port
[*]结合
二、基于IP
配置hosts，httpd.conf，eno
1、假设服务器已有IP为192.168.136.140，使用ifconfig在同一个网络接口eno16777736（或者eth0）绑定另外2个IP，或者同 nmtui 配置。可以进行ping探测。
# ifconfig eno16777736:192.168.136.143
# ifconfig eno16777736:192.168.136.144
2、修改/etc/hosts文件，添加一一对应的域名
# IP-Based
192.168.136.143 www3.example.com
1921.68.136.144 www4.example.com
3、建立虚拟主机存放网页的根目录
# /var/www 目录结构
# tree
.
├── cgi-bin
├── html
├── logs
│ ├── www1
│ │ ├── access_log
│ │ └── error_log
│ ├── www2
│ │ ├── access_log
│ │ └── error_log
│ ├── www3
│ │ ├── access_log
│ │ └── error_log
│ └── www4
│ ├── access_log
│ └── error_log
└── vhosts
├── www1
│ └── index.html
├── www2
│ └── index.html
├── www3
│ └── index.html
└── www4
└── index.html
index.html内容分别如下
# cat index.html ../www4/index.html
Holle world!
Welcom to www3.example.com site with IP-Based.
Holle world!
Welcom to www4.example.com site with IP-Based.
4、在httpd.conf中将附加配置文件httpd-vhosts.conf包含进来，接着修改httpd-vhosts.conf配置
# IP-Based
ServerAdmin webmaster@www1.example.com
ServerName www3.example.com
DocumentRoot "/var/www/vhosts/www3"
ErrorLog "/var/www/logs/www1/error_log"
CustomLog "/var/www/logs/www1/access_log" combined
ServerAdmin webmaster@www4.example.com
ServerName www4.example.com
DocumentRoot "/var/www/vhosts/www4"
ErrorLog "/var/www/logs/www4/error_log"
CustomLog "/var/www/logs/www4/access_log" combined
5、配置语法检查 httpd -S，可看到Name-Based和IP-Based共存。
# httpd -S
VirtualHost configuration:
192.168.136.143:80 www3.example.com (/etc/httpd/conf/httpd.conf:98)
192.168.136.144:80 www4.example.com (/etc/httpd/conf/httpd.conf:106)
*:80 is a NameVirtualHost
default server www1.example.com (/etc/httpd/conf/httpd.conf:82)
port 80 namevhost www1.example.com (/etc/httpd/conf/httpd.conf:82)
alias example1.com
port 80 namevhost www2.example.com (/etc/httpd/conf/httpd.conf:89)
ServerRoot: "/etc/httpd"
Main DocumentRoot: "/var/www/html"
Main ErrorLog: "/etc/httpd/logs/error_log"
Mutex authn-socache: using_defaults
Mutex default: dir="/run/httpd/" mechanism=default
Mutex mpm-accept: using_defaults
Mutex authdigest-opaque: using_defaults
Mutex proxy-balancer-shm: using_defaults
Mutex rewrite-map: using_defaults
Mutex authdigest-client: using_defaults
Mutex proxy: using_defaults
PidFile: "/run/httpd/httpd.pid"
Define: DUMP_VHOSTS
Define: DUMP_RUN_CFG
User: name="apache" id=48
Group: name="apache" id=48
6、重启服务 systemctl restart httpd.service，然后访问4个站点。
# curl www1.example.comwww2.example.com www3.example.com www4.example.com
Holle world!
welcome to www1.example.com site with Name-Based.
Holle world!
welcome to www2.example.com site with Name-Based.
Holle world!
Welcom to www3.example.com site with IP-Based.
Holle world!
Welcom to www4.example.com site with IP-Based.
# 通过IP或者域名访问3，4
# curl www3.example.com192.168.136.143:80www4.example.com 192.168.136.144:80
Holle world!
Welcom to www3.example.com site with IP-Based.
Holle world!
Welcom to www3.example.com site with IP-Based.
Holle world!
Welcom to www4.example.com site with IP-Based.
Holle world!
Welcom to www4.example.com site with IP-Based.
至此已完成了IP-Based的配置。

问题：用户如何配置和管理。
