需要先參考我的博客《Linux學(xué)習(xí)之Ubuntu 20.04在https://openresty.org下載源碼安裝Openresty 1.19.3.1，使用systemd管理OpenResty服務(wù)》安裝好Openresty。
虛擬域名可以使用讓不同的域名訪問到同一臺主機(jī)。
cd /usr/local/openresty切換當(dāng)前訪問目錄到/usr/local/openresty。

在/usr/local/openresty/nginx/conf/nginx.conf文件的http配置塊末尾添加上以下的內(nèi)容：

server {
        # 監(jiān)聽8000
        listen       8000;
        # 域名設(shè)為 www.sea.com
        server_name  www.sea.com;

        location / {
            # 訪問根目錄是html/sea
            root   html/sea;
            index  index.html index.htm;
        }
    }
server {
        # 監(jiān)聽8800
        listen       8800;
        # 域名設(shè)為 www.sea.com
        server_name  www.side.com;

        location / {
            # 訪問根目錄是html/side
            root   html/side;
            index  index.html index.htm;
        }
    }

/usr/local/openresty/nginx/conf/nginx.conf文件整體內(nèi)容如下：

worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  localhost;
        location / {
            root   html;
            index  index.html index.htm;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
    server {
        # 監(jiān)聽8000
        listen       8000;
        # 域名設(shè)為 www.sea.com
        server_name  www.sea.com;

        location / {
            # 訪問根目錄是html/sea
            root   html/sea;
            index  index.html index.htm;
        }
    }
    server {
        # 監(jiān)聽8800
        listen       8800;
        # 域名設(shè)為 www.sea.com
        server_name  www.side.com;

        location / {
            # 訪問根目錄是html/side
            root   html/side;
            index  index.html index.htm;
        }
    }
}

我使用的是vim編輯器，要是不知道vim編輯怎么使用，可以看一下我的博客。

/usr/local/openresty/nginx/sbin/nginx -t可以檢查一下格式和測試都是正常的。

/usr/local/openresty/nginx/sbin/nginx進(jìn)行啟動。

lsof -i:8000可以看到8000端口已經(jīng)被監(jiān)聽，lsof -i:8800可以看到8800端口也已經(jīng)被監(jiān)聽，lsof -i:7800沒有被監(jiān)聽，因?yàn)闆]有任何輸出，注意：7800端口只是測試一下，說明什么叫沒有被監(jiān)聽。

/usr/local/openresty/nginx/sbin/nginx再次進(jìn)行啟動，發(fā)現(xiàn)報(bào)錯(cuò)如下：

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8000 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8800 failed (98: Address already in use)

/usr/local/openresty/nginx/sbin/nginx -s stop可以停止nginx，/usr/local/openresty/nginx/sbin/nginx再次啟動。

netstat -ntpl | grep nginx查看一下nginx的監(jiān)聽端口。

接下來把下邊的內(nèi)容也添加到/usr/local/openresty/nginx/conf/nginx.confhttp配置塊里：

   server {
        # 監(jiān)聽9800
        listen       9800;
        # 域名設(shè)為 www.work.com
        server_name  www.work.com;

        location / {
            # 訪問根目錄是html/work
            root   html/work;
            index  index.html index.htm;
        }
    }

/usr/local/openresty/nginx/conf/nginx.conf文件整體內(nèi)容如下：

worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  localhost;
        location / {
            root   html;
            index  index.html index.htm;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }


    server {
        # 監(jiān)聽8000
        listen       8000;
        # 域名設(shè)為 www.sea.com
        server_name  www.sea.com;

        location / {
            # 訪問根目錄是html/sea
            root   html/sea;
            index  index.html index.htm;
        }
    }


    server {
        # 監(jiān)聽8800
        listen       8800;
        # 域名設(shè)為 www.sea.com
        server_name  www.side.com;

        location / {
            # 訪問根目錄是html/side
            root   html/side;
            index  index.html index.htm;
        }
    }
    
   server {
        # 監(jiān)聽9800
        listen       9800;
        # 域名設(shè)為 www.work.com
        server_name  www.work.com;

        location / {
            # 訪問根目錄是html/work
            root   html/work;
            index  index.html index.htm;
        }
    }
}

/usr/local/openresty/nginx/sbin/nginx -s reload可以在不斷開已有連接的基礎(chǔ)上重新加載/usr/local/openresty/nginx/conf/nginx.conf。

echo "127.0.0.1 www.sea.com www.side.com www.work.com" >> /etc/hosts將127.0.0.1 www.sea.com www.side.com www.work.com寫入/etc/hosts里邊。

mkdir /usr/local/openresty/nginx/html/sea /usr/local/openresty/nginx/html/side /usr/local/openresty/nginx/html/work在/usr/local/openresty/nginx/html創(chuàng)建三個(gè)目錄sea、side和work。

執(zhí)行下邊命令：

echo "hello sea" > /usr/local/openresty/nginx/html/sea/index.html # 在/usr/local/openresty/nginx/html/sea/index.html寫入 hello sea
echo "hello side" > /usr/local/openresty/nginx/html/side/index.html # 在/usr/local/openresty/nginx/html/side/index.html寫入 hello side
echo "hello work" > /usr/local/openresty/nginx/html/work/index.html # 在/usr/local/openresty/nginx/html/work/index.html 寫入 hello work

curl http://www.sea.com:8000可以訪問虛擬域名www.sea.com的8000端口。
curl http://www.side.com:8800可以訪問虛擬域名www.side.com的8800端口。
curl http://www.work.com:9800可以訪問虛擬域名www.work.com的9800端口。
