实验一:使用 web 服务演示安全上下文值的设定
[root@localhost ~] # systemctl restart nginx
通过客户端测试,出现 403 状态码
修改自定义目录的安全上下文的值:
[root@localhost ~] # chcon -t httpd_sys_content_t /www/ -R
也可以将自定义目录的安全上下文的值按照 /var/www/html 文件修改:
[root@localhost ~] # chcon -R --reference=/usr/share/nginx/html/index.html
/www
修改之后即可成功访问。
实验二:使用 web 服务端口的改变来演示端口的设定
[root@localhost ~] # vim /etc/httpd/conf.d/host.conf
[root@master-dns ~] # cat /etc/nginx/conf.d/test_port.conf
server {
listen 192 .168.168.153:80;
root /www/port/80;
location / {}
}
server {
listen 192 .168.168.153:10000;
root /www/port/10000;
location / {}
}
[root@localhost ~] # mkdir -pv /www/port/{80,10000}
[root@localhost ~] # echo the port is 80 > /www/port/80/index.html
[root@localhost ~] # echo the port is 10000 > /www/port/10000/index.html
[root@master-dns ~] # systemctl restart nginx
服务重启失败,查看日志
[root@localhost ~] # tail -f /var/log/messages
添加 10000 端口为服务端口:
[root@localhost ~] # semanage port -a -t http_port_t -p tcp 10000
[root@master-dns ~] # systemctl restart nginx
[root@master-dns ~] # curl 192.168.168.153:10000
the port is 10000
