nginx虚拟主机
使用yum安装nginx，使用如果命令查看nginx文件。
[root@centos1 ~]# rpm -qc nginx
/etc/logrotate.d/nginx
/etc/nginx/conf.d/default.conf
/etc/nginx/conf.d/ssl.conf
/etc/nginx/conf.d/virtual.conf
/etc/nginx/fastcgi.conf
/etc/nginx/fastcgi.conf.default
/etc/nginx/fastcgi_params
/etc/nginx/fastcgi_params.default
/etc/nginx/koi-utf
/etc/nginx/koi-win
/etc/nginx/mime.types
/etc/nginx/mime.types.default
/etc/nginx/nginx.conf
/etc/nginx/nginx.conf.default
/etc/nginx/scgi_params
/etc/nginx/scgi_params.default
/etc/nginx/uwsgi_params
/etc/nginx/uwsgi_params.default
/etc/nginx/win-utf
/etc/sysconfig/nginx
[root@centos1 conf.d]# cd /etc/nginx/conf.d/
[root@centos1 conf.d]# ls
default.conf ssl.conf virtual.conf
default.conf中定义中心主机
server {
listen (IP1:)80;
server_name www.a.com;
access_log logs/a.access.log main;
root /var/www/a.com/htdocs;
index index.html index.htm;
}
配置virtual.conf，添加虚拟主机。
基于端口的虚拟主机：
server {
listen 8080;
server_name www.b.com;
access_log logs/b.accesss.log main;
index index.html;
root /var/www/b.com/htdocs;
}
基于主机名的虚拟主机：
server {
listen 80;
server_name www.b.com;
access_log logs/b.accesss.log main;
index index.html;
root /var/www/b.com/htdocs;
}
基于IP地址的虚拟主机：
server {
listen (IP2:)80;
server_name www.b.com;
access_log logs/b.accesss.log main;
index index.html;
root /var/www/b.com/htdocs;
}
进行nginx语法检查：
[root@centos1 conf.d]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
然后重启nginx服务：
[root@centos1]#service nginx restart
设置默认虚拟主机：
如果访问的是IP地址，或者是一个未定义的主机名，则默认是返回第一个虚拟主机。我们可以定义默认虚拟机，当发生如上两种情况时，都返回默认虚拟主机所定义的网页。
语法如下：
server {
listen 80 default;
server_name _;
root /www/default;
index index.html;
}
