详解Nginx 虚拟主机配置的三种方式(基于端口)

Nginx配置虚拟主机支持3种方式:基于IP的虚拟主机配置,基于端口的虚拟主机配置,基于域名的虚拟主机配置。

2、Nginx基于端口的虚拟主机配置

如一台服务器只有一个IP或需要通过不同的端口访问不同的虚拟主机,可以使用基于端口的虚拟主机配置。

2.1 假设服务器有个IP地址为192.168.2.154

  [root@localhost conf]# ifconfig ens33:4 192.168.2.154/24 up  [root@localhost conf]# ifconfig  ens33:4: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500   inet 192.168.2.154 netmask 255.255.255.0 broadcast 192.168.2.255   ether 00:0c:29:16:90:ae txqueuelen 1000 (Ethernet)  

2.2 需要配置的虚拟主机分别为7081、8081和9081,配置主机的host文件便于测试。

  [root@localhost conf]# vim /etc/hosts  [root@localhost conf]# cat /etc/hosts|grep 192.168.2.154  192.168.2.154 www.test154.com

2.3 建立虚拟主机存放网页的根目录,并创建首页文件index.html

  [root@localhost conf]# cd /data/www/  [root@localhost www]# mkdir port  [root@localhost www]# cd port/  [root@localhost port]# mkdir 7081 8081 9081  [root@localhost port]# ls  7081 8081 9081  [root@localhost port]# echo "port 7081" > 7081/index.html  [root@localhost port]# echo "port 8081" > 8081/index.html  [root@localhost port]# echo "port 9081" > 9081/index.html

2.4 修改nginx.conf,将虚拟主机配置文件包含进主文件

  [root@localhost /]# cd /usr/local/nginx/conf/  [root@localhost conf]# ls  fastcgi.conf  fastcgi_params  koi-utf mime.types  nginx.conf  scgi_params  uwsgi_params  win-utf  fastcgi.conf.default fastcgi_params.default koi-win mime.types.default nginx.conf.default scgi_params.default uwsgi_params.default  [root@localhost conf]# vim nginx.conf

在nginx.conf文件末尾加入以下配置

  # 在http段中找到以下内容并删除每行前面的“#”   log_format main '$remote_addr - $remote_user [$time_local] "$request" '     '$status $body_bytes_sent "$http_referer" '     '"$http_user_agent" "$http_x_forwarded_for"';    # 配置文件结尾的最后一个“}”之前加入以下语句,如下所示  include vhost/*.conf  

2.5 编辑每个端口的配置文件

  [root@localhost vhost]# vim www.test154.7081.conf  [root@localhost vhost]# cat www.test154.7081.conf   server {   listen 192.168.2.154:7081;   # 配置成实际的域名,每个虚拟主机的配置文件域名都相同   #server_name www.test.com;     access_log /data/logs/www.test154.7081.log main;   error_log /data/logs/www.test154.7081.error.log;     location / {    root /data/www/port/7081;    index index.html index.htm;   }   }    [root@localhost vhost]# vim www.test154.8081.conf  [root@localhost vhost]# cat www.test154.8081.conf   server {   listen 192.168.2.154:8081;   # 配置成实际的域名,每个虚拟主机的配置文件域名都相同   #server_name www.test.com;     access_log /data/logs/www.test154.8081.log main;   error_log /data/logs/www.test154.8081.error.log;     location / {    root /data/www/port/8081;    index index.html index.htm;   }   }    [root@localhost vhost]# vim www.test154.9081.conf  [root@localhost vhost]# cat www.test154.9081.conf   server {   listen 192.168.2.154:9081;   # 配置成实际的域名,每个虚拟主机的配置文件域名都相同   #server_name www.test.com;     access_log /data/logs/www.test154.9081.log main;   error_log /data/logs/www.test154.9081.error.log;     location / {    root /data/www/port/9081;    index index.html index.htm;   }   }

2.6 创建日志文件,否则无法启动nginx

  [root@localhost /]# mkdir -p /data/logs  [root@localhost /]# touch /data/logs/www.test154.7081.log  [root@localhost /]# touch /data/logs/www.test154.7081.error.log  [root@localhost /]# touch /data/logs/www.test154.8081.log  [root@localhost /]# touch /data/logs/www.test154.8081.error.log  [root@localhost /]# touch /data/logs/www.test154.9081.log  [root@localhost /]# touch /data/logs/www.test154.9081.error.log  [root@localhost /]# ls /data/logs/  www.test154.7081.error.log www.test154.8081.error.log www.test154.9081.error.log  www.test154.7081.log www.test154.8081.log www.test154.9081.log

2.7 先测试配置文件然后再启动nginx

  [root@localhost /]# cd /usr/local/nginx/sbin/  [root@localhost sbin]# ./nginx -t  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  # 启动nginx  [root@localhost sbin]# ./nginx

2.8 测试文件

  [root@localhost ~]# curl http://www.test154.com:7081  port 7081  [root@localhost ~]# curl http://www.test154.com:8081  port 8081  [root@localhost ~]# curl http://www.test154.com:9081  port 9081

附:配置过程中的问题

1、最后测试时发生的问题

  [root@localhost sbin]# curl http://www.test154.com:7081  curl: (7) Failed connect to www.test154.com:7081; 拒绝连接  [root@localhost sbin]# curl 192.168.2.154:7081  curl: (7) Failed connect to 192.168.2.154:7081; 拒绝连接  

解决方法:

1.1 使用以下命令查看Nginx是否在监听相应的端口

  [root@localhost conf]# netstat -lnt  Active Internet connections (only servers)  Proto Recv-Q Send-Q Local Address  Foreign Address  State  tcp 0 0 0.0.0.0:111  0.0.0.0:*  LISTEN  tcp 0 0 192.168.2.153:80 0.0.0.0:*  LISTEN  tcp 0 0 192.168.2.152:80 0.0.0.0:*  LISTEN  tcp 0 0 192.168.2.151:80 0.0.0.0:*  LISTEN  tcp 0 0 0.0.0.0:8080  0.0.0.0:*  LISTEN  tcp 0 0 192.168.2.154:8081 0.0.0.0:*  LISTEN  tcp 0 0 0.0.0.0:22  0.0.0.0:*  LISTEN  tcp 0 0 192.168.2.154:9081 0.0.0.0:*  LISTEN  tcp 0 0 127.0.0.1:25  0.0.0.0:*  LISTEN  tcp 0 0 192.168.2.154:7081 0.0.0.0:*  LISTEN  tcp6 0 0 :::111   :::*   LISTEN  tcp6 0 0 :::22   :::*   LISTEN  tcp6 0 0 :::23   :::*   LISTEN  tcp6 0 0 ::1:25   :::*   LISTEN  

1.2 若Nginx未监听相应端口则重启Nginx服务,再不行重启服务器
