一、虚机主机的三种方式

1、基于IP

2、基于IP+端口

3、基于域名

官网文档:http://httpd.apache.org/docs/2.4/

二、安装Apache

1、系统环境

[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)
[root@localhost ~]# ip ad
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eno16777736: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:0c:29:5c:ff:91 brd ff:ff:ff:ff:ff:ff
inet 192.168.253.128/24 brd 192.168.253.255 scope global dynamic eno16777736
valid_lft 1388sec preferred_lft 1388sec
inet6 fe80::20c:29ff:fe5c:ff91/64 scope link
valid_lft forever preferred_lft forever

2、yum安装

[root@localhost ~]# yum install -y httpd
*****
======================================================================================================================================================
Package 架构 版本 源 大小
======================================================================================================================================================
正在安装:
httpd x86_64 2.4.6-80.el7.centos base 2.7 M
为依赖而安装:
apr x86_64 1.4.8-3.el7_4.1 base 103 k
apr-util x86_64 1.5.2-6.el7 base 92 k
httpd-tools x86_64 2.4.6-80.el7.centos base 89 k
mailcap noarch 2.1.41-2.el7 base 31 k
***
已安装:
httpd.x86_64 0:2.4.6-80.el7.centos 作为依赖被安装:
apr.x86_64 0:1.4.8-3.el7_4.1 apr-util.x86_64 0:1.5.2-6.el7 httpd-tools.x86_64 0:2.4.6-80.el7.centos mailcap.noarch 0:2.1.41-2.el7 完毕!

可以查看安装了内容

[root@localhost ~]# rpm -ql httpd | less

3、配置Selinux文件,SELINUX=disabled。

[root@localhost ~]# vim /etc/selinux/config

SELINUX=disabled

SELINUXTYPE=targeted

或者临时关闭

[root@localhost ~]# setenforce 0

4、关闭防火墙

[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.

5、启动httpd服务,访问测试

[root@localhost ~]# systemctl start httpd

三、修改主配置文件

1、查看apache主配置文件,确保存在以下配置,因为等下需要在conf.d/创建虚机主机配置。

[root@localhost ~]# vim  /etc/httpd/conf/httpd.conf

IncludeOptional conf.d/*.conf

2、另外,把 Require all denied默认拒绝访问设置为允许访问: Require all granted,方便测试。

<Directory />
AllowOverride none
# Require all denied
Require all granted
</Directory>

四、新增虚拟主机配置文件

1、添加基于多个IP的虚拟主机

1)创建配置文件

    [root@localhost ~]# cd /etc/httpd/conf.d/
[root@localhost conf.d]# vim virtual.conf
<VirtualHost 192.168.253.128:80>
ServerName a.com
DocumentRoot "/www/a.com/" #网页路径
</VirtualHost> <VirtualHost 192.168.253.129:80>
ServerName b.com
DocumentRoot "/www/b.com/" #网页路径
</VirtualHost>

2)网卡绑定多个IP(我的网卡名是eno16777736,不是eth0)

[root@localhost conf.d]# ip addr add 192.168.253.129 dev eno16777736
[root@localhost conf.d]# ip add
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eno16777736: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:0c:29:5c:ff:91 brd ff:ff:ff:ff:ff:ff
inet 192.168.253.128/24 brd 192.168.253.255 scope global dynamic eno16777736
valid_lft 1542sec preferred_lft 1542sec
inet 192.168.253.129/32 scope global eno16777736
valid_lft forever preferred_lft forever
inet6 fe80::20c:29ff:fe5c:ff91/64 scope link
valid_lft forever preferred_lft forever

3)创建虚机主机a.com和b.com的主页面

[root@localhost conf.d]# mkdir -pv /www/{a.com,b.com}
mkdir: 已创建目录 "/www"
mkdir: 已创建目录 "/www/a.com"
mkdir: 已创建目录 "/www/b.com"
[root@localhost conf.d]# vim /www/a.com/index.html

<h1>Hello,a.com</h1>

[root@localhost conf.d]# vim /www/b.com/index.html

<h1>Hello,b.com</h1>

4)检查配置文件是否正常

    [root@localhost conf.d]# httpd -t
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
Syntax OK

5)重启httpd服务

[root@localhost conf.d]# systemctl restart httpd

6)打开浏览器,查看结果

2、配置基于IP+端口的虚拟主机

1)创建配置文件

    [root@localhost ~]# cd /etc/httpd/conf.d/
[root@localhost conf.d]# vim virtual.conf
<VirtualHost 192.168.253.128:80>
ServerName a.com
DocumentRoot "/www/a.com/"
</VirtualHost> <VirtualHost 192.168.253.128:8080>
ServerName b.com
DocumentRoot "/www/b.com/"
</VirtualHost>

2)修改httpd主配置文件,在Listen 80下面添加一行监控8080端口

[root@localhost conf.d]# vim /etc/httpd/conf/httpd.conf

Listen 8080

3)创建虚机主机a.com和b.com的主页面(如果前面已经创建就不用重复)

    [root@localhost conf.d]# mkdir -pv /www/{a.com,b.com}
mkdir: 已创建目录 "/www"
mkdir: 已创建目录 "/www/a.com"
mkdir: 已创建目录 "/www/b.com" [root@localhost conf.d]# vim /www/a.com/index.html

<h1>Hello,a.com</h1>

[root@localhost conf.d]# vim /www/b.com/index.html

<h1>Hello,b.com</h1>

4)检查配置文件

    [root@localhost conf.d]# httpd -t
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
Syntax OK

5)重启httpd服务

[root@localhost conf.d]# systemctl restart httpd

6)打开浏览器,查看结果

3、基于域名的虚拟主机

1)创建配置文件

    [root@localhost ~]# cd /etc/httpd/conf.d/
[root@localhost conf.d]# vim virtual.conf
<VirtualHost *:80>
ServerName a.com
DocumentRoot "/www/a.com/"
</VirtualHost> <VirtualHost *:80>
ServerName b.com
DocumentRoot "/www/b.com/"
</VirtualHost>

2)修改物理主机hosts文件(C:\Windows\System32\drivers\etc),因为这里是因为物理机去访问Apache服务器

添加:

192.168.253.128 a.com

192.168.253.128 b.com

3)物理主机ping域名测试

4)创建虚机主机a.com和b.com的主页面(如果前面已经创建就不用重复)

    [root@localhost conf.d]# mkdir -pv /www/{a.com,b.com}
mkdir: 已创建目录 "/www"
mkdir: 已创建目录 "/www/a.com"
mkdir: 已创建目录 "/www/b.com"
[root@localhost conf.d]# vim /www/a.com/index.html

<h1>Hello,a.com</h1>

[root@localhost conf.d]# vim /www/b.com/index.html

<h1>Hello,b.com</h1>

5)检查配置文件

    [root@localhost conf.d]# httpd -t
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
Syntax OK

6)重启httpd服务

[root@localhost conf.d]# systemctl restart httpd

7)打开浏览器,查看结果

五、扩展虚机主机配置文件

1、先修改回apache主配置文件,设置 Require all denied默认拒绝访问

<Directory />
AllowOverride none
Require all denied </Directory>

这时候再去访问以上的三种配置虚机主机,会全部访问不了。因此需要针对虚机目录设置访问权限。

2、修改虚拟主机配置文件

    [root@localhost ~]# cd /etc/httpd/conf.d/
[root@localhost conf.d]# vim virtual.conf

<VirtualHost *:80>
        #绑定的主域
        ServerName a.com
        #绑定的子域名
        ServerAlias www.test.com
        #网站主目录
        DocumentRoot "/www/a.com/"
        #错误日志目录
        ErrorLog  "/var/log/httpd/a.com/error.log"
        #访问日志目录
       CustomLog "/va/log/httpd/a.com.access.log"
<Directory "www/a.com/">
        Options FollowSymLinks
        AllowOverride All
        #允许任意访问
        Require all granted
</Directory>
</VirtualHost>

3、创建日志目录

  1. [root@localhost b.com]# cd /var/log/httpd/
  2. [root@localhost httpd]# mkdir a.com
  3. [root@localhost httpd]# ll
  4. 总用量 60
  5. -rw-r--r--. 1 root root 37976 1月 23 22:26 access_log
  6. drwxr-xr-x. 2 root root 6 1月 23 22:41 a.com
  7. -rw-r--r--. 1 root root 17795 1月 23 22:38 error_log
  8. [root@localhost httpd]# cd a.com/
  9. [root@localhost a.com]# touch error.log
  10. [root@localhost a.com]# touch access.log

日志目录记得更改属主和属组为Apache,否则httpd启动失败

[root@localhost httpd]# chown -R apache:apache a.com/

4、配置指定IP可以访问虚拟主机(可以单个IP,也可以是一个网段)

[root@localhost conf.d]# vim /etc/httpd/conf.d/virtual.conf
  1. <VirtualHost *:80>
  2. #绑定的主域
  3. ServerName a.com
  4. #绑定的子域名
  5. ServerAlias www.test.com
  6. #网站主目录
  7. DocumentRoot "/www/a.com/"
  8. #错误日志目录
  9. ErrorLog "/var/log/httpd/a.com/error.log"
  10. #访问日志目录
  11. CustomLog "/va/log/httpd/a.com.access.log"
  12. <Directory "www/a.com/">
  13. Options FollowSymLinks
  14. AllowOverride All
  15. #允许任意访问
  16. Require ip 192.168.253.0/24
  17. </Directory>

5、配置指定用户可以访问虚拟主机

[root@localhost conf.d]# vim /etc/httpd/conf.d/virtual.conf
 
    <VirtualHost *:80>
#绑定的主域
ServerName a.com
#绑定的子域名
ServerAlias www.test.com
#网站主目录
DocumentRoot "/www/a.com/"
#错误日志目录
ErrorLog "/var/log/httpd/a.com/error.log"
#访问日志目录
CustomLog "/va/log/httpd/a.com.access.log"
<Directory "www/a.com/">
Options FollowSymLinks
AllowOverride authconfig
AuthType basic
AuthName "Restrict area"
AuthUserFile "etc/httpd/.htpasswd"
Require valid-user
</Directory>

创建用户文件,第一次创建的时候要加-c,以后创建都不用加-c,否则会覆盖原数据

    [root@localhost conf.d]# pwd
/etc/httpd/conf.d
[root@localhost conf.d]# htpasswd -h
htpasswd: illegal option -- h
Usage:
htpasswd [-cimBdpsDv] [-C cost] passwordfile username
htpasswd -b[cmBdpsDv] [-C cost] passwordfile username password htpasswd -n[imBdps] [-C cost] username
htpasswd -nb[mBdps] [-C cost] username password
-c Create a new file.
-n Don't update file; display results on stdout.
-b Use the password from the command line rather than prompting for it.
-i Read password from stdin without verification (for script usage).
-m Force MD5 encryption of the password (default).
-B Force bcrypt encryption of the password (very secure).
-C Set the computing time used for the bcrypt algorithm
(higher is more secure but slower, default: 5, valid: 4 to 31).
-d Force CRYPT encryption of the password (8 chars max, insecure).
-s Force SHA encryption of the password (insecure).
-p Do not encrypt the password (plaintext, insecure).
-D Delete the specified user.
-v Verify password for the specified user.
On other systems than Windows and NetWare the '-p' flag will probably not work.
The SHA algorithm does not use a salt and is less secure than the MD5 algorithm.
[root@localhost conf.d]# htpasswd -c -m /etc/httpd/.htpasswd tom
New password:
Re-type new password:
Adding password for user tom

重启httpd服务

    [root@localhost conf.d]# httpd -t
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
Syntax OK
[root@localhost conf.d]# systemctl restart httpd
