};
[root@localhost etc]# cp /var/named/named.localhost /var/named/vm1.com.zone //拷贝模板到解析文件中

编译安装nginx
[root@localhost ~]# yum -y install \ //安装环境
gcc \
gcc-c++ \
make \
pcre-devel \

……省略部分
一、配置web虚拟主机
1、配置基于域名的虚拟web主机
[root@localhost conf]# vim /usr/local/nginx/conf/nginx.conf
server {
listen 80;
server_name www.vm1.com;
charset utf-8;
access_log logs/www.vm1.access.log;
location / {
root /var/www/html/vm1/;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
server {
listen 80;
server_name www.vm2.com;
charset utf-8;
access_log logs/www.vm2.access.log;
location / {
root /var/www/html/vm2/;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
[root@localhost conf]# mkdir -p /var/www/html/vm1/
[root@localhost conf]# mkdir -p /var/www/html/vm2/
[root@localhost html]# cd vm1
[root@localhost vm1]# vim index.html
[root@localhost vm1]# systemctl restart nginx
[root@localhost vm1]# vim index.html
[root@localhost vm1]# cd ..
[root@localhost html]# cd vm2
[root@localhost vm2]# vi index.html
[root@localhost vm2]# systemctl restart nginx
去另一台机器测试
[root@localhost ~]# vi /etc/hosts
20.0.0.12 www.vm1.com
20.0.0.12 www.vm2.com
登录网页测试
2、配置基于ip的虚拟web主机（添加双网卡IP1:20.0.0.12；IP2:192.168.30.10）
[root@localhost conf]# vim /usr/local/nginx/conf/nginx.conf
server {
listen 20.0.0.12:80;
# server_name www.vm1.com;
charset utf-8;
access_log logs/www.vm1.access.log;
location / {
root /var/www/html/vm1/;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
server {
listen 192.168.30.10:80;
# server_name www.vm2.com
charset utf-8;
access_log logs/www.vm2.access.log;
location / {
root /var/www/html/vm2/;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
去另一台虚拟机测试
3、基于端口的虚拟web主机
[root@localhost conf]# vim /usr/local/nginx/conf/nginx.conf
server {
listen 20.0.0.12:800;
# server_name www.vm1.com;
charset utf-8;
access_log logs/www.vm1.access.log;
location / {
root /var/www/html/vm1/;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
server {
listen 20.0.0.12:8080;
# server_name www.vm2.com
charset utf-8;
access_log logs/www.vm2.access.log;
location / {
root /var/www/html/vm2/;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
测试
二、Nginx访问状态统计
启用HTTP_STUB_STATUS状态统计模块
配置编译参数时添加–with-http_stub_status_module
nginx -V查看已安装的Nginx是否包含HTTP_STUB_STATUS模块
[root@localhost conf]# nginx -V //可以看到已经安装了统计模块
nginx version: nginx/1.15.9
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC)
configure arguments: --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module
[root@localhost conf]# vi nginx.conf
location / {
root html;
index index.html index.htm;
}
location /status {
stub_status on;
access_log off;
}
[root@localhost conf]# systemctl restart nginx
访问20.0.0.12/status测试
三、用户访问控制
1、基于授权的访问控制
[root@localhost conf]# yum -y install httpd-tools //安装httpd工具软件包
[root@localhost conf]# htpasswd -c /usr/local/nginx/passwd.db user /创建访问用户，第一次创建需要-c创建用户数据文件，生成用户密码认证文件
[root@localhost conf]# cat /usr/local/nginx/passwd.db //查看用户数据文件
user:3p9ocItYYOa6U
[root@localhost conf]# vim /usr/local/nginx/conf/nginx.conf
location / {
root html;
index index.html index.htm;
auth_basic "secret";
auth_basic_user_file /usr/local/nginx/passwd.db;
}
[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]# systemctl restart nginx
登入网站测试
2、基于客户端的访问控制
通过客户端lP地址，决定是否允许对页面访问
配置规则:
deny P/IP段:拒绝某个IP或IP段的客户端访问
allow IP/IP段:允许某个IP或IP段的客户端访问
规则从上往下执行，如匹配则停止，不再往下匹配
