Nginx高级使用

1.用户认证

客户端访问限制
deny 客户端地址； 拒绝访问
allow 客户端地址； 允许访问

rpm -q  httpd-tools

yum -y install  httpd-tools

user

htpasswd -h
[root@lk_Cloud ~]#  htpasswd -c /usr/local/nginx/conf/user.txt admin
New password:
Re-type new password:
Adding password for user admin

cat /usr/local/nginx/conf/user.txt
admin:ytAJoGw8jjbJI

vim nginx.conf

location / {
 root /admindir;
 index index.html;
 #allow 1.1.1.1;
 #deny all;
 auth_basic "please in put user and password";
 auth_basic_user_file "/usr/local/nginx/conf/user.txt";
 }

2.源码包平滑升级

查看现在版本

/usr/local/nginx/sbin/nginx -V

下载最新源码包

编译选项务必保持一致

./configure --prefix=/usr/local/nginx --user=www --group=www --with-http_ssl_module

make

先备份老版本启动文件

mv /usr/local/nginx/sbin/nginx    /usr/local/nginx/sbin/nginxold

make之后产生的objs目录

cp objs/nginx      /usr/local/nginx/sbin/

在新版本解压目录下执行 make upgrade

3.防盗链

server {
.......
location ~* \.(png|jpeg|jpg|gif)$ {
valid_referers none blocked www.kamilliu.com .kamilliu.com ;
 if ($invalid_referer){
 #rewrite ^/ http://1.1.1.254/err.html;
 return 404;
 }
}
.....
}
