yum install httpd-tools -y
2.生成用户名密码文件
htpasswd -c /etc/nginx/conf.d/.ngpasswd foms
回车输入密码

3.安装nginx(略)
server {
listen 80;
server_name localhost;
?
#access_log /var/log/nginx/host.access.log main;
?
location / {
auth_basic "input you user name and password";
auth_basic_user_file /etc/nginx/conf.d/.ngpasswd;
proxy_pass http://192.168.205.106:8081;
}
}
重启nginx后访问

也可以配置一个虚拟访问路径(访问时加上虚拟路径)
server {
listen 80;
server_name localhost;
location /login/ {
auth_basic "input you user name and password";
auth_basic_user_file /etc/nginx/conf.d/.ngpasswd;
proxy_pass http://192.168.205.106:8081/;
}
http://192.168.205.106/login
