Question

nginx如何配置域名

Answer 1

方法一：多个.conf方法（优点是灵活，缺点就是站点比较多配置起来麻烦）
这里以配置2个站点（2个域名）为例，n 个站点可以相应增加调整，假设：
IP地址: 192.168.1.100
域名1 example1.com 放在 /www/example1
域名2 example2.com 放在 /www/example2

配置 nginx virtual hosting 的基本思路和步骤如下：
把2个站点 example1.com, example2.com 放到 nginx 可以访问的目录 /www/
给每个站点分别创建一个 nginx 配置文件 example1.com.conf，example2.com.conf, 并把配置文件放到 /usr/local/nginx/vhosts/
然后在 /usr/local/nginx/nginx.conf 里面加一句 include 把步骤2创建的配置文件全部包含进来（用 * 号）
重启 nginx
1、打开 /usr/local/nginx/nginix.conf 文件，在相应位置加入 include 把以上2个文件包含进来
user www www;
worker_processes 1;

# main server error log
error_log /usr/local/nginx/log/nginx/error.log ;
pid /usr/local/nginx/nginx.pid;

events {
worker_connections 51200;
}
# main server config
http {
include mime.types;
default_type application/octet-stream;
log_format main ‘$remote_addr – $remote_user [$time_local] $request ‘
‘”$status” $body_bytes_sent “$http_referer” ‘
‘”$http_user_agent” “$http_x_forwarded_for”‘;

sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
gzip on;

server {
listen 80;
server_name _;
access_log /usr/local/nginx/log/nginx/access.log main;
server_name_in_redirect off;
location / {
root /usr/share/nginx/html;
index index.html;
}
}
# 包含所有的虚拟主机的配置文件
include /usr/local/nginx/vhosts/*;
}

2、在 /usr/local/nginx 下创建 vhosts 目录
mkdir /usr/local/nginx/vhosts

3、在 /usr/local/nginx/vhosts/ 里创建一个名字为 example1.com.conf 的文件，把以下内容拷进去
server {
listen 80;
server_name example1.com www. example1.com;

access_log /www/access_ example1.log main;

location / {
root /www/example1.com;
index index.php index.html index.htm;
}

error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
location ~ .php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /www/example1.com/$fastcgi_script_name;
include fastcgi_params;
}

location ~ /.ht {
deny all;
}
}

3、在 /usr/local/nginx/vhosts/ 里创建一个名字为 example2.com.conf 的文件，把以下内容拷进去
server {
listen 80;
server_name example2.com www. example2.com;

access_log /www/access_ example1.log main;

location / {
root /www/example2.com;
index index.php index.html index.htm;
}

error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
location ~ .php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /www/example2.com/$fastcgi_script_name;
include fastcgi_params;
}

location ~ /.ht {
deny all;
}
}

5、重启 Nginx

/etc/init.d/nginx restart

方法二：动态目录方法（优点是方便，每个域名对应一个文件夹，缺点是不灵活）

这个简单的方法比起为每一个域名建立一个 vhost.conf 配置文件来讲，只需要在现有的配置文件中增加如下内容：

# Replace this port with the right one for your requirements
# 根据你的需求改变此端口
listen 80; #could also be 1.2.3.4:80 也可以是1.2.3.4:80的形式
# Multiple hostnames seperated by spaces. Replace these as well.
# 多个主机名可以用空格隔开，当然这个信息也是需要按照你的需求而改变的。
server_name star.yourdomain.com *.yourdomain.com http://www.*.yourdomain.com/;
#Alternately: _ *
#或者可以使用：_ * (具体内容参见本维基其他页面)
root /PATH/TO/WEBROOT/$host;
error_page 404 http://yourdomain.com/errors/404.html;
access_log logs/star.yourdomain.com.access.log;
location / {
root /PATH/TO/WEBROOT/$host/;
index index.php;
}
# serve static files directly

# 直接支持静态文件 (从配置上看来不是直接支持啊)
location ~* ^.+.(jpg|jpeg|gif|css|png|js|ico|html)$ {
access_log off;
expires 30d;
}
location ~ .php$ {
# By all means use a different server for the fcgi processes if you need to
# 如果需要，你可以为不同的FCGI进程设置不同的服务信息
fastcgi_pass 127.0.0.1:YOURFCGIPORTHERE;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /PATH/TO/WEBROOT/$host/$fastcgi_script_name;
fastcgi_param QUERY_STRING $query_string;
fastcgi_param REQUEST_METHOD $request_method;
fastcgi_param CONTENT_TYPE $content_type;
fastcgi_param CONTENT_LENGTH $content_length;
fastcgi_intercept_errors on;
}
location ~ /.ht {
deny all;
}

最后附另外一个二级域名匹配的方法

绑定域名
server_name *.abcd.com;
获取主机名
if ( $host ~* (.*).(.*).(.*))
{
set $domain $1;
}
定义目录
root html/abc/$domain/;
location /
{
root html/abcd/$domain;
index index.html index.php;
