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 "$1" instart)$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 1esac
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
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      25954/nginx: master 
tcp        0      0 192.168.136.10:22       192.168.136.2:59246     ESTABLISHED 8049/sshd: root@pts 
tcp        0      0 192.168.136.10:48214    59.111.0.251:80         TIME_WAIT   -
[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.confserver_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mainlocation / {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.confserver {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

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

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）
