nginx虚拟主机

nginx的虚拟主机配置跟apache的配置类似也有IP与域名配置两种，下面我们就实践一下；

一、基于域名的虚拟主机的配置；

1、我们在此复习一下DNS的配置；

[root@mgmserver /]# hostname

mgmserver.com

[root@/]#yum install bind*

[root@mgmserver /]#rpm -ivh /var/cdiso/Server/caching-nameserver-9.3.6-4.P1.el5.i386.rpm

[root@mgmserver /]# cd /var/named/chroot/etc/

[root@mgmserver etc]# cp -p named.caching-nameserver.conf named.conf

[root@mgmserver etc]#vi named.conf

其他的不用修改只在视图里面添加zone就可以了；

view localhost_resolver {

match-clients { any; };

match-destinations { any; };

recursion yes;

include "/etc/named.rfc1912.zones";

zone "mgmserver.com" {

type master;

file "mgmserver.com.zone";

allow-update { any;};

};

zone "0.168.192.in-addr.arpa" {

type master;

file "192.168.0.rev";

allow-update { any;};

};

[root@mgmserver etc]# cd ../var/named/

下面有很多模板文件。Named.ca就是根区域的数据库文件，localhost.zone这个是正向解析的数据库文件，named.local这个是反向解析的数据库文件。

[root@mgmserver named]# cp localhost.zone mgmserver.com.zone

[root@mgmserver named]# cp named.local 192.168.0.rev

编辑 这两个文件

[root@mgmserver named]#vi mgmserver.com.zone

$TTL 86400

@ IN SOA mgmserver.com. root.mgmserver.com. (

1997022700 ; Serial

28800 ; Refresh

14400 ; Retry

3600000 ; Expire

86400 ) ; Minimum

IN NS mgmserver.com.

IN MX 10 mail.mgmserver.com.

mail IN A 192.168.0.28

server IN A 192.168.0.33

www IN A 192.168.0.28

web IN CNAME www.mgmserver.com.

[root@mgmserver named]#vi 192.168.0.rev

$TTL 86400

@ IN SOA mgmserver.com. root.mgmserver.com. (

42 ; serial (d. adams)

3H ; refresh我

15M ; retry

1W ; expiry

1D ) ; minimum

IN NS mgmserver.com.

28 IN PTR mgmserver.com.

33 IN PTR server.mgmserver.com.

简单的配置一下，我们要使用的www.mgmserver.com 与web.mgmserver.com这两个域名来测试；

[root@mgmserver named]# named-checkconf /var/named/chroot/etc/named.conf

[root@mgmserver named]# service named restart

停止 named： [确定]

启动 named： [确定]

我们到另外一台机器测试





到这里我们的为nginx的配置www.mgmserver.com 与web.mgmserver.com这两个域名都可以使用过了；

2、配置nginx配置文件，添加两个虚拟主机

[root@mgmserver conf]# vi nginx.conf





[root@mgmserver www.mgmserver.com_web]# /usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf

[emerg]: "server" directive is not allowed here in /usr/local/nginx/conf/nginx.conf:45

configuration file /usr/local/nginx/conf/nginx.conf test failed

第一次出现错误提示，查找原来是少了一个大括号，添加上就可以了；在检测就OK了；

[root@mgmserver www.mgmserver.com_web]# /usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf

the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

configuration file /usr/local/nginx/conf/nginx.conf test is successful

[root@mgmserver www.mgmserver.com_web]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

启动nginx

[root@mgmserver conf]# cd /var/web/

[root@mgmserver web]# ls

web.mgmserver.com_web www.mgmserver.com_web

在这两个目录里面分别建立一个index.html文件保存

到另外一个server2003上面测试









两个静态页面已基本OK;

二、基于IP的虚拟之际的配置；

[root@mgmserver conf]# ifconfig

[root@mgmserver ~]# ifconfig eth0:2 192.168.0.38 broadcast 192.168.0.255 netmask 255.255.255.0 up

[root@mgmserver ~]# route add -host 192.168.0.38 dev eth0:2

[root@mgmserver ~]# ifconfig

从另外一台win2003上测试





结果都是通的;通过使用ifconfig与route添加的ip地址别名在服务器重启后就会消失了,可以将这两条语句添加到/etc/rc.local 文件中,让系统开机时自动运行;

#vi /etc/rc.local

ifconfig eth0:1 192.168.0.37 broadcast 192.168.0.255 netmask 255.255.255.0 up

route add -host 192.168.0.37 dev eth0:1

ifconfig eth0:2 192.168.0.38 broadcast 192.168.0.255 netmask 255.255.255.0 up

route add -host 192.168.0.38 dev eth0:2

保存就可以了;

下面我们在nginx的配置文件中nginx.conf分别对192.168.0.28 ,192.168.0.37,192.168.0.38三个IP配置虚拟主机，

server {

listen 192.168.0.28:80;

server_name 192.168.0.28;

access_log logs/192.168.0.28.access.log main;

location / {

root /var/web/192.168.0.28;

index index.html index.htm;

}

}

server {

listen 192.168.0.37:80;

server_name 192.168.0.37;

access_log logs/192.168.0.37.access.log main;

location / {

root /var/web/192.168.0.37;

index index.html index.htm;

}

}

server {

listen 192.168.0.38:80;

server_name 192.168.0.38;

access_log logs/192.168.0.38.access.log main;

location / {

root /var/web/192.168.0.38;

index index.html index.htm;

}

}

[root@mgmserver ~]# kill -QUIT `cat /usr/local/nginx/logs/nginx.pid`

[root@mgmserver ~]# ps -ef |grep nginx

root 5284 4213 0 13:39 pts/2 00:00:00 vi nginx.conf

root 5356 4053 0 13:49 pts/1 00:00:00 grep nginx

[root@mgmserver ~]# /usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf

the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

configuration file /usr/local/nginx/conf/nginx.conf test is successful

[root@mgmserver ~]# /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

在/var/web下面分别建立三个目录

192.168.0.28 192.168.0.37 192.168.0.38

分别在三个目录中放一个index.html 文件 分别写上自己的IP地址；

从win2003上面访问；













上面就是nginx基于域名、ip访问的配置，掌握住格式，就很好配置了。

结合apache配置：

1.httpd.conf

Listen 8801

Listen 8802

nginx.conf

include /usr/local/nginx/conf/vhost.conf

2.httpd-vhosts.conf

<VirtualHost *:8801>

ServerAdmin webmaster@dummy-host.example.com

DocumentRoot "/var/www/a"

<Directory "/var/www/a">

Options FollowSymLinks

AllowOverride None

Order allow,deny

Allow from all

</Directory>

ServerName www.a.com:8801

ServerAlias www.a.com:8801

ErrorLog "logs/a.com-error_log"

DirectoryIndex index.html index.html.var index.php

CustomLog "logs/a.com-access_log" common

</VirtualHost>

NameVirtualHost *:8802

<VirtualHost *:8802>

ServerAdmin webmaster@dummy-host.example.com

DocumentRoot "/var/www/b"

<Directory "/var/www/b">

Options FollowSymLinks

AllowOverride None

Order allow,deny

Allow from all

</Directory>

ServerName www.b.com:8802

ServerAlias www.b.com:8802

ErrorLog "logs/b.com-error_log"

DirectoryIndex index.html index.html.var index.php

CustomLog "logs/b.com-access_log" common

</VirtualHost>

3.nginx vhost.conf 配置

server {

listen 81;

server_name www.a.com;

access_log logs/a.access.log main;

location / {

root /var/www/a;

index index.html index.htm index.php;

}

location ~ .*\.(php?|cgi|pl|py)$ {

proxy_pass http://127.0.0.1:8801;
}

}

server {

listen 81;

server_name www.b.com;

access_log logs/b.access.log main;

location / {

root /var/www/b;

index index.html index.htm index.php;

}

location ~ .*\.(php?|cgi|pl|py)$ {

proxy_pass http://127.0.0.1:8802;
}

}
