Apache+mod_jk+Tomcat（5）-----Apache 基于端口的virtual host

虚拟主机（Virtual Host）

 

概念：同一台机器上搭建属于不同域名或者基于不同IP的多个网站服务技术，可以为运行在同一台物理机器上的各个网站指配不同的IP和端口，也可以让多个网站拥有不同的域名。

根据需求创建虚拟主机

 

1.需求

同一台主机上运行两套应用程序，通过端口区分（基于端口的虚拟主机）（一套程序是通过50001端口，另外一套是通过50002端口），基于之前搭建的环境上。

 

2.实施内容

1）因为虚拟主机是基于端口的，所以修改配置文件/etc/httpd/conf/httpd.conf

Listen 80

⇒

Listen 50001

Listen 50002

 

2)定义虚拟主机的配置文件

 

第一个虚拟主机的配置文件

/etc/httpd/conf.d/virtual.d/virtual1.conf

<VirtualHost *:50001>
   ServerName 192.168.100.29
   DocumentRoot "/var/www/html_virtual1"
   <Directory /var/www/html_virtual1>
     Options  FollowSymLinks
     AllowOverride None
     Require all granted
   </Directory>
   CustomLog logs/access_virtual1_log combined env=!nolog
   ErrorLog logs/error_virtual1.log
   ErrorDocument 400 /error/40X.json
   ErrorDocument 401 /error/40X.json
   ErrorDocument 403 /error/40X.json
   ErrorDocument 404 /error/40X.json
   ErrorDocument 405 /error/40X.json
   ErrorDocument 408 /error/40X.json
   ErrorDocument 410 /error/40X.json
   ErrorDocument 411 /error/40X.json
   ErrorDocument 412 /error/40X.json
   ErrorDocument 413 /error/40X.json
   ErrorDocument 414 /error/40X.json
   ErrorDocument 415 /error/40X.json
   ErrorDocument 500 /error/50X.json
   ErrorDocument 501 /error/50X.json
   ErrorDocument 502 /error/50X.json
   ErrorDocument 503 /error/50X.json
   ErrorDocument 506 /error/50X.json
   Alias /error/ "/var/www/error_virtual1/"
   IncludeOptional conf.d/mod_jk_virual1.conf
 </VirtualHost>

第二个虚拟主机的配置文件

 

/etc/httpd/conf.d/virtual.d/virtual2.conf

<VirtualHost *:50002>
   ServerName 192.168.100.29
   DocumentRoot "/var/www/html_virtual2"
   <Directory /var/www/html_virtual2>
     Options  FollowSymLinks
     AllowOverride None
     Require all granted
   </Directory>
   CustomLog logs/access_virtual2_log combined env=!nolog
   ErrorLog logs/error_virtual2.log
   ErrorDocument 400 /error/40X.json
   ErrorDocument 401 /error/40X.json
   ErrorDocument 403 /error/40X.json
   ErrorDocument 404 /error/40X.json
   ErrorDocument 405 /error/40X.json
   ErrorDocument 408 /error/40X.json
   ErrorDocument 410 /error/40X.json
   ErrorDocument 411 /error/40X.json
   ErrorDocument 412 /error/40X.json
   ErrorDocument 413 /error/40X.json
   ErrorDocument 414 /error/40X.json
   ErrorDocument 415 /error/40X.json
   ErrorDocument 500 /error/50X.json
   ErrorDocument 501 /error/50X.json
   ErrorDocument 502 /error/50X.json
   ErrorDocument 503 /error/50X.json
   ErrorDocument 506 /error/50X.json
   Alias /error/ "/var/www/error_virtual2/"
   IncludeOptional conf.d/mod_jk_virual2.conf
 </VirtualHost>

 

3）为了让apache启动时，加载这两个配置文件，在/etc/httpd/conf/httpd.conf中追加下面的配置

IncludeOptional conf.d/virtual.d/*.conf

 

4）分别创建两条虚拟主机的文档目录,并在里面放上需要访问的html资源

mkdir /var/www/html_virtual1

virutal1test.html

mkdir /var/www/html_virtual2

 virutal2test.html

 

5）从上面各自虚拟主机的配置文件来看，都定义了各自的mod_jk文件，所以创建mod_jk文件,worker还是使用以前定义好的tomat1.

 

/etc/httpd/conf.d/mod_jk_virtual1.conf

<IfModule mod_jk.c>

JkMount /virtual1/* tomcat1

</IfModule>

 

/etc/httpd/conf.d/mod_jk_virtual2.conf

<IfModule mod_jk.c>

JkMount /virtual2/* tomcat1

</IfModule>

 

6）在tomcat里放上两个war包，一个名叫virutal1,virtual2

 

7）重启apache,重启tomcat

systemctl restart httpd

 

/opt/tomcat/bin/shutdown.sh

/opt/tomcat/bin/startup.sh

 

8）测试apache的静态资源是否能正常访问

http://192.168.100.29:50001/virtual1test.html

结果：正常显示

 

http://192.168.100.29:50002/virtual2test.html

结果：正常显示

 

9）确认log

/var/log/httpd/access_virtual1_log

10.0.210.135 - - [03/Aug/2017:15:34:59 +0900] "GET /virtual1test.html HTTP/1.1" 200 53 "-" "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; InfoPath.3)"

 

/var/log/httpd/access_virtual2_log

10.0.210.135 - - [03/Aug/2017:15:45:54 +0900] "GET /virtual2test.html HTTP/1.1" 200 53 "-" "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; InfoPath.3)"

 

10)通过apache&mod_jk&tomcat访问tomcat的资源

http://192.168.100.29:50001/virtual1/index.jsp

结果：正常显示

 

http://192.168.100.29.50002/virtual2/index.jsp

结果：正常显示

 

11)确认log

/var/log/httpd/access_virtual1_log

10.0.210.135 - - [03/Aug/2017:15:52:15 +0900] "GET /virtual1/index.jsp HTTP/1.1" 200 290 "-" "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; InfoPath.3)"

 

/var/log/httpd/access_virtual2_log

10.0.210.135 - - [03/Aug/2017:15:52:55 +0900] "GET /virtual2/index.jsp HTTP/1.1" 200 286 "-" "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; InfoPath.3)"

 

总结：总体来说，配的很顺利，但是对于一些概念，还需要学习，比如对于ServerName的概念，我就不是特别理解。看到httpd.conf里的解释是这样的解释的

#
# ServerName gives the name and port that the server uses to identify itself.
# This can often be determined automatically, but we recommend you specify
# it explicitly to prevent problems during startup.
#
# If your host doesn't have a registered DNS name, enter its IP address here.
#

If your host doesn't have a registered DNS name, enter its IP address here.
