基于IP地址的虚拟主机配置

[root@localhost ~]# cd /usr/local/nginx/conf/

[root@localhost conf]# mkdir ../html/ipv1
[root@localhost conf]# touch ../html/ipv1/index.html
[root@localhost conf]# echo “IP based virtual host 1 OK”>../html/ipv1/index.html
[root@localhost conf]# mkdir ../html/ipv2
[root@localhost conf]# touch ../html/ipv2/index.html
[root@localhost conf]# echo “IP based virtual host 2 OK”>../html/ipv2/index.html

在nginx配置文件中添加基于IP的虚拟机主机配置
[root@localhost conf]# vi nginx.conf
server {
listen       192.168.244.136:80;
server_name  192.168.244.136;
access_log   logs/ipv1_access.log;

location / {
root   html/ipv1;
index  index.html index.htm;
}
}

server {
listen       192.168.244.138:80;
server_name  192.168.244.138;
access_log   logs/ipv2_access.log;

location / {
root   html/ipv2;
index  index.html index.htm;
}
}

确认修改后的配置文件语法正确性
[root@localhost conf]# nginx -t -c /usr/local/nginx/conf/nginx.conf
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
[root@localhost conf]#

基于主机名的虚拟机主机配置

建立测试目录及文件

[root@localhost conf]# mkdir ../html/nv1
[root@localhost conf]# touch ../html/nv1/index.html
[root@localhost conf]# echo “Name based virtual host 1 OK”>../html/nv1/index.html
[root@localhost conf]# mkdir ../html/nv2
[root@localhost conf]# touch ../html/nv2/index.html
[root@localhost conf]# echo “Name based virtual host 2 OK”>../html/nv2/index.html
[root@localhost conf]# mkdir ../html/nv3
[root@localhost conf]# touch ../html/nv3/index.html
[root@localhost conf]# echo “Name based virtual host 3 OK”>../html/nv3/index.html

在nginx配置文件中添加基于主机名的虚拟机主机配置
server {
listen       80;
server_name  nv1.linuxcache.net;
access_log   logs/nv1_access.log;

location / {
root   html/nv1;
index  index.html index.htm;
}
}

server {
listen       80;
server_name  nv2.linuxcache.net nv3.linuxcache.net;
access_log   logs/nv2_access.log;

location / {
root   html/nv2;
index  index.html index.htm;
}
}

server {
listen       80;
server_name  *.linuxcache.cn;
access_log   logs/nv3_access.log;

location / {
root   html/nv3;
index  index.html index.htm;
}
}

修改Windows客户机主机文件将测试域名指向虚拟机IP地址
