nginx代理WebService配置
write by donaldhan, 2017-12-15 21:00在使用ngnix做WebService服务器的负载均衡器的时候出现出现如下错误：

我很是疑问，命名ngnix监听端口是8080，为什么，调用WebService的时候，会跑到80端口，我们ngnix代理声明如下：
upstream www.donald.com {
least_conn;
server www.donald.com:8380;
server www.donald.com:8180;
server www.donald.com:8280;
}
server {
listen 8080;
server_name www.donald.com;
charset UTF-8;
access_log logs/host.access.log;
location / {
root /ws;
index index.jsp index.php index.html index.htm
proxy_connect_timeout 10;
proxy_send_timeout 30;
proxy_read_timeout 30;
proxy_pass http://www.donald.com; #upstream www.donald.com 代理
}
访问WebService服务的wsdl，发现 soap:address location 地址确实80，而不是8080，很是疑问：
<xsd:schema><xsd:import namespace="http://www.cxf.service/service/" schemaLocation="http://www.donald.com:80/ws/service?xsd=1"/>
</xsd:schema>
...
<service name="serviceService"><port name="servicePort" binding="tns:servicePortBinding"><soap:address location="http://www.donald.com:80/ws/service"/></port></service>
搜索相关资料发现，Nginx默认反向后的端口为80，因此存在被代理后的端口为80的问题，这就导致访问出错。主要原因在Nginx的配置文件的host配置时没有设置响应的端口。Host配置只有host，没有对应的port,这就导致在被代理的地方取得错误的端口。所以修改配置如下：
upstream www.donald.com {
least_conn;
server www.donald.com:8380;
server www.donald.com:8180;
server www.donald.com:8280;
}
server {
listen 8080;
server_name www.donald.com;
charset UTF-8;
access_log logs/host.access.log;
location / {
root /ws;
index index.jsp index.php index.html index.htm
proxy_connect_timeout 10;
proxy_send_timeout 30;
proxy_read_timeout 30;
proxy_pass http://www.donald.com; #upstream www.donald.com 代理
proxy_set_header Host $host:$server_port;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
主要是代理头部配置proxy_set_header：
proxy_set_header Host $host:$server_port;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
再次访问WebService的服务wsdl，这是 soap:address location 端口为8080，可以正常访问。
