内外网映射需要注意的问题（session和ip地址有hash关系）

session和ip地址有hash关系，尤其在内外网替换不完全的时候,比如退出使用192.168.13.99/hb_phonebank_web/logout,

登录使用http://116.236.184.238:8006/hb_phonebank_web/，这时session对不上，明显的就是退出没有清掉，重新登录没有

换用户名

外网前端请求的要是外网地址（使用端能访问的地址），之后nginx再转为内网，upstream是nginx内部用的，nginx的装机地址才是外网要映射的地址

外网开映射：

116.236.184.238:8006 ---》 192.168.13.99:80

116.236.184.238:8007 ---》 192.168.13.99:8126

nginx实现：

外网内网

服务端：http://116.236.184.238:8006/hb_phonebank_web/ ----》 http://192.168.13.99/hb_phonebank_web/

静态页面：http://116.236.184.238:8007/dashboard ----》 http://192.168.13.99:8126/dashboard

外网这种用端口映射的时候，可能会出现退出的时候丢失了端(http://116.236.184.238/hb_phonebank_web/ )，内网80可以省略所以没有问题，nginx 需配置proxy_set_header Host $http_host;

$host不能再用

nginx 配置:

user nginx;

worker_processes 1;

error_log /var/log/nginx/error.log warn;

pid /var/run/nginx.pid;

events {

worker_connections 1024;

}

http {

include /etc/nginx/mime.types;

default_type application/octet-stream;

log_format main '$remote_addr - $remote_user [$time_local] "$request" '

'$status $body_bytes_sent "$http_referer" '

'"$http_user_agent" "$http_x_forwarded_for"';

access_log /var/log/nginx/access.log main;

sendfile on;

#tcp_nopush on;

keepalive_timeout 65;

#gzip on;

proxy_buffer_size 128k;

proxy_buffers 32 32k;

proxy_busy_buffers_size 128k;

proxy_temp_file_write_size 128k;

client_header_buffer_size 64k;

large_client_header_buffers 4 64k;

# include /etc/nginx/conf.d/*.conf;

upstream 116.236.184.238 {

ip_hash;

server 192.168.13.97:8080;

server 192.168.13.99:8080;

}

server {

listen 80;//本机地址的80，192.168.13.99:80

server_name localhost;

#charset koi8-r;

#access_log /var/log/nginx/host.access.log main;

location / {

proxy_read_timeout 300;

proxy_pass http://116.236.184.238;

# proxy_set_header Host $host;

proxy_set_header Host $http_host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

#error_page 404 /404.html;

# redirect server error pages to the static page /50x.html

error_page 500 502 503 504 /50x.html;

location = /50x.html {

root /usr/share/nginx/html;

}

# proxy the PHP scripts to Apache listening on 127.0.0.1:80

#location ~ \.php$ {

# proxy_pass http://127.0.0.1;

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

# include fastcgi_params;

# deny access to .htaccess files, if Apache's document root

#location ~ /\.ht {

# deny all;

}

server {

listen 8126;

server_name localhost;

location / {

root /home/distph;

try_files $uri $uri/ /index.html;

index index.html index.htm;

}

error_page 500 502 503 504 /50x.html;

location = /50x.html {

root html;

}

location /hb_phonebank_web {

client_max_body_size 10M;

proxy_pass http://116.236.184.238;

proxy_redirect off;

#proxy_set_header Host $host;

proxy_set_header Host $http_host;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

proxy_set_header X-Real-IP $remote_addr;

}

shrio配置：

<map>

</map>

</property>

</bean>

退出的时候，也换成http://116.236.184.238:8006/hb_phonebank_web/logout
