nginx负载均衡&文件服务器配置&虚拟目录&代理&refer防盗链

1、负载均衡，/usr/local/nginx/nginx.conf添加stream即可

http{
....
}

stream {
server {
listen          8080 reuseport;
proxy_pass      netty;
}
upstream netty {
server  192.168.180.68:8080;
server  192.168.180.69:8080;
}
}

2、添加文件服务器，在http中(如果性能不行，可参考http://blog.csdn.net/b_h_l/article/details/17508499)

server {
listen       80;
server_name  192.168.180.67;

location / {
root   /opt/test;
index  index.php index.html index.htm;
autoindex on;
autoindex_exact_size off;
autoindex_localtime on;
}
}

3、虚拟目录()

server {
listen       80;
server_name  localhost;
location / {
root /404.html;
index  index.php index.html index.htm;
}
location /recfile {
alias /home/netrec/;
index  index.php index.html index.htm;
autoindex on;
autoindex_exact_size off;
autoindex_localtime on;
}
location /test {
proxy_pass http://ip:port; }
}

nginx的root和alias指令的区别

nginx配置下有两个指定目录的执行，root和alias

location /img//var/www/image/

location /img//var/www/image

alias是一个目录别名的定义，root则是最上层目录的定义。还有一个重要的区别是alias后面必须要用“/”结束，否则会找不到文件的。。。而root则可有可无~~
4、refer防盗链https://help.aliyun.com/knowledge_detail/6708458.html?pos=2
5、重定向到某个地址

server {
listen 9000;
server_name www.abc.com;
rewrite ^/(.*)$ http://180.133.180.198:9002/$1 permanent;
}
