主域名多端口访问
在dns nameserver设置a记录
将 指向服务器ip
开放所需端口，修改nginx配置文件
比如我们有两个服务分别开放在80端口和8080端口
如果有iptable，先开放端口：
iptables -a input -ptcp --dport 80 -j accept iptables -a input -ptcp --dport 8080 -j accept
修改配置文件:
#path: /usr/local/nginx/conf/nginx.conf
server {
listen 80;
server_name www.xxx.com;
access_log /data/www/log/33.33.33.33_nginx.log combined;
index index.html index.htm index.php;
include /usr/local/nginx/conf/rewrite/none.conf;
root /data/www/website/33.33.33.33:80;
location ~ [^/]\.php(/|$) {
fastcgi_pass unix:/dev/shm/php-cgi.sock;
fastcgi_index index.php;
include fastcgi.conf;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|ico)$ {
expires 30d;
access_log off;
}
location ~ .*\.(js|css)?$ {
expires 7d;
access_log off;
}
}
server {
listen 8080;
server_name a.xxx.com;
access_log /data/www/log/33.33.33.33:8080_nginx.log combined;
index index.html index.htm index.php;
include /usr/local/nginx/conf/rewrite/none.conf;
root /data/www/website/33.33.33.33:8080;
location ~ [^/]\.php(/|$) {
fastcgi_pass unix:/dev/shm/php-cgi.sock;
fastcgi_index index.php;
include fastcgi.conf;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|ico)$ {
expires 30d;
access_log off;
}
location ~ .*\.(js|css)?$ {
expires 7d;
access_log off;
}
}关键就是两个 server 段配置，你也可以把这两段拆成两个配置文件，放到
/etc/nginx/conf.d/
目录下面；
子域名多端口访问
这种访问比较傻，因为你的8080端口的访问需要 http://xxx.com:8080 这样的格式；
而且如果有两个不同的cgi，比如80端口对应一个php web服务， 8080端口对应一个nodejs web服务；而我们的nodejs自带web服务，已经在8080端口监听了，这怎么办？
这个时候我们需要nginx的反向代理功能，并在dns server上面增加一条a记录，最终实现
www.xxx.com 访问80端口
a.xxx.com 通过nginx转发访问8080端口服务
增加一条a记录
将 a.xxx.com 指向服务器ip
nginx配置模板如下：
#path: /usr/local/nginx/conf/nginx.conf
server {
listen 80;
server_name www.xxx.com;
access_log /data/www/log/33.33.33.33_nginx.log combined;
index index.html index.htm index.php;
include /usr/local/nginx/conf/rewrite/none.conf;
root /data/www/website/33.33.33.33:80;
location ~ [^/]\.php(/|$) {
fastcgi_pass unix:/dev/shm/php-cgi.sock;
fastcgi_index index.php;
include fastcgi.conf;
}
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|ico)$ {
expires 30d;
access_log off;
}
location ~ .*\.(js|css)?$ {
expires 7d;
access_log off;
}
}
server {
listen 80;
listen [::]:80;
server_name a.xxx.com;
proxy_connect_timeout 300s;
proxy_send_timeout 300s;
proxy_read_timeout 300s;
fastcgi_send_timeout 300s;
fastcgi_read_timeout 300s;
location / {
proxy_pass http://127.0.0.1:3000;
proxy_http_version 1.1;
proxy_set_header upgrade $http_upgrade;
proxy_set_header connection 'upgrade';
proxy_set_header host $host;
proxy_cache_bypass $http_upgrade;
try_files $uri $uri/ =404;
}
}nginx重新载入配置文件
nginx -s reload
