Nginx 虚拟主机配置的三种方式(三)(基于域名)

3、Nginx基于域名的虚拟主机配置

使用基于域名的虚拟主机配置是比较流行的方式,可以在同一个IP上配置多个域名并且都通过80端口访问。

3.1 假设服务器有个IP地址为192.168.2.155

[root@localhost ~]# ifconfig ens33:5 192.168.2.155/24 up
[root@localhost ~]# ifconfig
ens33:5: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.2.155  netmask 255.255.255.0  broadcast 192.168.2.255
        ether 00:0c:29:16:90:ae  txqueuelen 1000  (Ethernet)

3.2 192.168.2.155对应的域名如下,配置主机的host文件便于测试

[root@localhost ~]# vim /etc/hosts
[root@localhost ~]# cat /etc/hosts|grep 192.168.2.155
192.168.2.155 www.oa.com
192.168.2.155 www.bbs.com
192.168.2.155 www.test.com

3.3 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 ~]# cd /data/www/
[root@localhost www]# mkdir www.oa.com
[root@localhost www]# mkdir www.bbs.com
[root@localhost www]# mkdir www.test.com
[root@localhost www]# echo www.oa.com > www.oa.com/index.html
[root@localhost www]# echo www.bbs.com > www.bbs.com/index.html
[root@localhost www]# echo www.test.com > www.test.com/index.html

3.4 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

3.5 编辑每个域名的配置文件(每个虚拟主机的配置文件)

[root@localhost conf]# cd vhost/
[root@localhost vhost]# cat www.oa.com.conf
    server {
        listen       192.168.2.155:80;
        server_name  www.oa.com;

        access_log   /data/logs/www.oa.com.log main;
        error_log    /data/logs/www.oa.com.error.log;

        location / {
            root   /data/www/www.oa.com;
            index  index.html index.htm;
        }
    }

[root@localhost vhost]# cat www.bbs.com.conf
    server {
        listen       192.168.2.155:80;
        server_name  www.bbs.com;

        access_log   /data/logs/www.bbs.com.log main;
        error_log    /data/logs/www.bbs.com.error.log;

        location / {
            root   /data/www/www.bbs.com;
            index  index.html index.htm;
        }
    }

[root@localhost vhost]# cat www.test.com.conf
    server {
        listen       192.168.2.155:80;
        server_name  www.test.com;

        access_log   /data/logs/www.test.com.log main;
        error_log    /data/logs/www.test.com.error.log;

        location / {
            root   /data/www/www.test.com;
            index  index.html index.htm;
        }
    }

[root@localhost vhost]# cat /data/www/www.oa.com/index.html
www.oa.com
[root@localhost vhost]# cat /data/www/www.bbs.com/index.html
www.bbs.com
[root@localhost vhost]# cat /data/www/www.test.com/index.html
www.test.com

3.6 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.oa.com.log
[root@localhost /]# touch /data/logs/www.oa.com.error.log
[root@localhost /]# touch /data/logs/www.bbs.com.log
[root@localhost /]# touch /data/logs/www.bbs.com.error.log
[root@localhost /]# touch /data/logs/www.test.com.log
[root@localhost /]# touch /data/logs/www.test.com.error.log
[root@localhost /]# ls /data/logs/
www.oa.com.error.log  www.bbs.com.error.log  www.test.com.error.log
www.oa.com.log        www.bbs.com.log        www.test.com.log

3.7 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

3.8 测试文件

[root@localhost vhost]# curl http://www.oa.com
www.oa.com
[root@localhost vhost]# curl http://www.bbs.com
www.bbs.com
[root@localhost vhost]# curl http://www.test.com
www.test.com

附:配置过程中的问题

1、最后测试时发生的问题

[root@localhost ~]# curl http://www.oa.com
curl: (7) Failed connect to www.oa.com:80; 拒绝连接

决解方法:
查看Nginx是否在监听相应的端口。

[root@localhost ~]# 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      0 192.168.2.155:80        0.0.0.0:*               LISTEN

tcp        0      0 127.0.0.1:25            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、配置虚拟主机文件时要加上监听的IP地址,每个虚拟主机配置文件都一样。

 listen       192.168.2.155:80;

2、配置完成后要重启服务器
