Nginx 虚拟主机配置的三种方式（二）（基于端口）

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 0.0.0.0:8080            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
