nginx负载均衡解决图片css等静态资源无法加载问题

ngnix做负载均衡，首先修改ngnix.conf如下

upstream server_lb{
server localhost:8080;
server localhost:8081;
}

#注释原有的配置
#location / {
#    root   /usr/share/nginx/html;
#    index  index.html index.htm;
#}

添加

location / {
proxy_pass        http://server_lb; proxy_set_he
4000
ader Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header REMOTE-HOST $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

}

到此，我的项目可以打开了，也显示了部分图片，但是还是有一些图片因为路径的问题不显示，各种尝试后，发现tomcat去掉项目名后运行 就可以正常显示了

具体步骤如下

打开tomcat/conf/server.xml

找到下面代码

<Host appBase="webapps" autoDeploy="true" name="localhost" unpackWARs="true">

然后在下面加一句

<Context docBase="F:\tomcat2\webapps\WebRoot" path="" reloadable="false"/>

docBase里的是你项目所在的路径

重启后，开启tomcat，开启nginx就可以实现负载均衡了
