配置DNS域名
nginx认识
Nginx是一款高性能的Web服务器软件,主要用于提供网上信息浏览服务,为高并发网站的应用场景而设计,可以在Linux、macOS和Windows等操作系统中运行,它的优点包括性能高、稳定性好、结构模块化、配置简单以及资源消耗非常低等。拥有HTTPS访问、gzip压缩、虚拟主机和URL重写等功能,不但可以搭配FastCGI程序处理动态请求,还可以用于代理、反向代理、负载均衡和缓存服务器等功能。

基于域名虚拟主机
配置DNS
root@localhost ~]# yum -y install bind
[root@localhost ~]# vim /etc/named.conf
options {
listen-on port 53 { any; };
listen-on-v6 port 53 { ::1; };
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
memstatistics-file "/var/named/data/named_mem_stats.txt";
recursing-file "/var/named/data/named.recursing";
secroots-file "/var/named/data/named.secroots";
allow-query { any; };
[root@localhost ~]# vim /etc/named.rfc1912.zones
zone "benet.com" IN {
type master;
file "benet.com.zone";
allow-update { none; };
};
zone "accp.com" IN {
type master;
file "accp.com.zone";
allow-update { none; };
};
[root@localhost ~]# cd /var/named/
[root@localhost named]# cp -p named.localhost benet.com.zone
[root@localhost named]# vim benet.com.zone
www IN A 192.168.136.10
[root@localhost named]# setenforce 0
[root@localhost named]# iptables -F
[root@localhost named]# systemctl stop firewalld
[root@localhost named]# systemctl start named
安装环境
[root@localhost named]# yum -y install gcc gcc-c++ pcre-devel zlib-devel
安装nginx
[root@localhost named]# tar zxvf nginx-1.12.2.tar.gz -C /opt/
[root@localhost opt]# cd nginx-1.12.2/
[root@localhost opt]#useradd -M -s /sbin/nologin nginx
[root@localhost nginx-1.12.2]# ./configure \
> --prefix=/usr/local/nginx \
> --user=nginx \
> --group=nginx \
> --with-http_stub_status_module
[root@localhost nginx-1.12.2]#make && make install
[root@localhost nginx-1.12.2]# cd /usr/local/nginx/
[root@localhost nginx]# ls
conf配置文件 html 默认站点 logs日志 sbin
制作管理脚本
[root@localhost nginx]# ln -s /usr/local/nginx/sbin/* /usr/local/sbin/ 便于系统可以识别
[root@localhost nginx]# cd /etc/init.d/ 重建服务
[root@localhost init.d]# vim nginx 创建管理脚本
#!/bin/bash
# chkconfig: - 99 20
#description: nginx service Control Script
PROG="/usr/local/nginx/sbin/nginx"
PIDF="/usr/local/nginx/logs/nginx.pid"
case "$1" in
start)
$PROG
;;
stop)
kill -s QUIT $(cat $PIDF)
;;
restart)
$0 stop
$0 start
;;
reload)
kill -s HUP $(cat $PIDF)
;;
*)
echo "Usage: $0 {start|stop|restart|reload}"
exit 1
esac
exit 0
[root@localhost init.d]# chmod +x nginx
[root@localhost init.d]# chkconfig --add nginx 便于servers管理
[root@localhost init.d]# yum -y install net-tools
[root@localhost init.d]# netstat -ntap | grep 80

[root@localhost init.d]#service nginx star
不同的域名访问不同得到网站
[root@localhost named]# cd /usr/local/nginx/conf/
[root@localhost conf]# vim nginx.conf
server_name www.benet.com;
charset utf-8; 开启字符级
access_log logs/www.kgc.com.access.log; 去掉#开启日志 加入www.kgc.com 去掉main
location / {
root /var/www/html/kgc; 开启站点
index index.html index.htm;
删除21到24 行
删除44到47
删除49到56 行
删除49到54 行
删除49到56行
创建虚拟主机
46 server {
47 listen 80; 监听地址
48 server_name www.benet.com; 域名
49 charset utf-8; 对应字符级
50 access_log logs/www.benet.com.access.log; 访问日志
51 location / {
52 root /var/www/html/benet; 站点目录
53 index index.html index.htm; 支持文件类型
54 }
55 error_page 500 502 503 504 /50x.html; 错误故障
56 location = /50x.html {
57 root html;
58 }
59 }
开启服务
[root@localhost conf]# 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
写入网页
[root@localhost ~]# mkdir -p /var/www/html/kgc
[root@localhost ~]# mkdir -p /var/www/html/benet
[root@localhost html]# echo "this is accp web" > kgc/index.html
[root@localhost html]# echo "this is benet web" > benet/index.html
[root@localhost conf]# service nginx restart
基于不同端口不同配置
[root@localhost html]# cd /usr/local/nginx/conf/
[root@localhost conf]# vim nginx.conf
server {
listen 192.168.136.10:80;
server_name www.benet.com;
charset utf-8;
access_log logs/www.benet.com.access.log;
location / {
root /var/www/html/benet;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
server {
listen 192.168.136.10:8080;
server_name www.benet.com;
charset utf-8;
access_log logs/www.benet8080.com.access.log;
location / {
root /var/www/html/benet8080;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
写入网页
[root@localhost conf]# cd /var/www//html/
[root@localhost html]# mkdir benet8080
[root@localhost html]# echo "this is benet8080 web" > benet8080/index.html
[root@localhost conf]# 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
访问不同地址的域名
添加一个网卡ens36并查看一下ens36网卡信息,修改一下区域配置文件
配置DNS区域配置文件
[root@localhost named]# vim kgc.com.zone
www IN A 192.168.136.136
[root@localhost named]# systemctl restart named
在win10中查看一下解析地址
注释掉8080端口的内容,保证不影响
修改一下kgc的ip地址
[root@localhost named]# cd /usr/local/nginx/conf/
[root@localhost conf]# vim nginx.conf
验证一下是否成功并开启
[root@localhost conf]# 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
[root@localhost conf]# service nginx restart
访问不同域名的IP地址
[root@localhost conf]# vim nginx.conf
开启服务
[root@localhost conf]# service nginx restart
开一台win7的服务器
解析一下地址
网页查看一下

结论:当我们配置没有问题时候可以找别的方法去解决,比如换一台客户终端测试(可能是客户端的问题)
