使用nginx后让tomcat的localhost_access_log获得真实IP

配置nginx

在location节点下面加入如下代码

proxy_set_header 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;

修改tomcat的server.xml配置文件

找到如下配置

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

修改成如下即可

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="%{X-Real-IP}i %l %u %t &quot;%r&quot; %s %b" />
