Nginx多域名代理以及Dnsmasq服务器部署
1、 ubuntu16.04下安装Nginx（通过ubuntu安装源进行安装）
$:sudo apt-get update
$:sudo apt-get install nginx
安装完成之后，通过:
$:nginx -v 可查看nginx软件版本
到此安装成功。说明：如果安装网络环境无法FQ，则可通过修改ubuntu安装源，再执行update和install操作。修改安装源具体步骤如下：
a、安装源原文件备份：
$:sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
b、编辑源列表文件：
$:sudo vim /etc/apt/sources.list
c、将该文件内容删除，然后添加如下内容（三者选其一）：

2、Nginx配置文件修改
a、编辑nginx.conf配置文件：
$:vim /etc/nginx/nginx.conf
文件内容如下：
user www www;
#user nobody nobody;
worker_processes 4;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
#log_format main '$remote_addr - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
client_max_body_size 100M;
#gzip on;
#server {
# listen 80;
# server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
# location / {
# root html;
# index index.html index.htm;
# }
# location ~ \.php {
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index /index.php;
# include /usr/local/nginx/conf/fastcgi_params;
# fastcgi_split_path_info ^(.+\.php)(/.+)$;
# fastcgi_param PATH_INFO $fastcgi_path_info;
# fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
# fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
# }
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
# error_page 500 502 503 504 /50x.html;
# location = /50x.html {
# root html;
# }
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
#}
include ./vhosts/*.conf;
# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;
# location / {
# root html;
# index index.html index.htm;
# }
#}
# HTTPS server
#
#server {
# listen 443 ssl;
# server_name localhost;
# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;
# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
}
b、在nginx文件目录下添加vhost文件目录：
/etc/nginx$:mkdir vhosts
c、在vhosts文件下添加serverA.conf、serverB.conf（根据实际需要，配置多少个域名就配置多少个.conf文件）
示例1：
/etc/nginx/vhosts$:vim serverA.conf
编辑内容如下：
server {
listen 80;
server_name www.A.com; #绑定域名
index index.htm index.html index.php; #默认文件
root /opt/www/Aserver/dist/; #网站根目录路径
#include location.conf; #调用其他规则，也可去除
location / {
add_header 'Access-Control-Allow-Origin' "*";
add_header 'Access-Control-Allow-Credentials' "true";
try_files $uri $uri/ /index.php?$query_string;
}
location /api {
proxy_set_header Host $proxy_host;
proxy_pass http://api.D.com; #配置的接口域名
proxy_buffer_size 128k;
proxy_buffers 32 32k;
proxy_busy_buffers_size 128k;
}
location ~ \.php {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index /index.html; #网站根目录路径下的index.htm index.html index.php，根据实际已有文件去填
include /etc/nginx/fastcgi_params; #根据实际nginx安装路径去填写
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
示例2：
/etc/nginx/vhosts$:vim serverB.conf
编辑内容如下：
server {
listen 80;
server_name www.B.com api.D.com; #绑定域名(绑定2个域名，中间空格间隔开，api开头的可作为接口域名：见示例1)
index index.htm index.html index.php; #默认文件
root /opt/www/Bserver/public/; #网站根目录
location / {
add_header 'Access-Control-Allow-Origin' "*";
add_header 'Access-Control-Allow-Credentials' "true";
try_files $uri $uri/ /index.php?$query_string;
}
location ~ \.php {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index /index.php; #网站根目录路径下的index.htm index.html index.php，根据实际已有文件去填
include /etc/nginx/fastcgi_params; #根据实际nginx安装路径去填写
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
示例3：
/etc/nginx/vhosts$:vim serverC.conf
编辑内容如下：
server {
listen 80;
server_name www.C.com; #绑定域名
index index.htm index.html index.php; #默认文件
root /opt/www/Cserver/dist/; #网站根目录
#include location.conf; #调用其他规则，也可去除
location / {
add_header 'Access-Control-Allow-Origin' "*";
add_header 'Access-Control-Allow-Credentials' "true";
try_files $uri $uri/ /index.php?$query_string;
}
location ~ \.php {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index /index.html; #网站根目录路径下的index.htm index.html index.php，根据实际已有文件去填
include /etc/nginx/fastcgi_params; #根据实际nginx安装路径去填写
fastcgi_split_path_info ^(.+\.php)(/.+)$;
fastcgi_param PATH_INFO $fastcgi_path_info;
fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
}
说明：示例1、2、3中，其中3最为简单，配置单任意域名网站；示例1示例2中，示例2的其中一个域名作为示例1的接口域名，方便示例1调用示例2的接口。【在配置时根据实际需要需配置自己所需的域名】
d、配置好nginx代理服务器后，在nginx/sbin目录下使用如下命令：
nginx/sbin$:./nginx -t #测试是否成功
nginx/sbin$:./nginx -s reload #重启nginx服务
e、在/etc/hosts文件中，编辑添加配置的域名：
IP www.A.com
IP www.B.com
IP www.C.com
IP api.D.com
说明：IP指部署网站所在的服务器的IP地址，如网站部署在192.168.5.10上，则IP就设为该IP地址
3、Dnsmasq服务器配置
a、安装Dnsmasq：
$:sudo apt-get install dnsmasq
b、编辑dnsmasq的配置文件：
$:sudo vi /etc/dnsmasq.conf
# or if you want it to read another file, as well as /etc/hosts, use
# this.
#addn-hosts=/etc/banner_add_hosts
addn-hosts=/etc/hosts #将此行取消注释
b、重启Dnsmasq服务：
$:systemctl restart dnsmasq
4、测试局域网是否能正常访问（两种方法）
方法a、将所有局域网内的客户端网络DNS均设为Dnsmasq服务器IP地址 打开网络和共享中心->本地连接->属性->IPV4->使用下面的DNS服务器地址，将Dnsmasq服务器IP地址填入 浏览器分别打开
www.A.com
www.B.com
www.C.com
api.D.com
观察能否正常访问。
方法b、所有局域网客户端电脑配置host文件 计算机->C盘（系统盘锁在位置）->windows->System32->drivers->etc，编辑添加hosts文件，内容同2中的e，完成后保存。
IP www.A.com
IP www.B.com
IP www.C.com
IP api.D.com
说明：IP指部署网站所在的服务器的IP地址，如网站部署在192.168.5.10上，则IP就设为该IP地址 浏览器分别打开www.A.com;www.B.com;www.C.com;api.D.com，观察能否正常访问
