Back-end tomcat logs get the real IP, not the nginx server's IP

First 1, modify the Nginx configuration file

Add in nginx.conf

Proxy_set_header x-forwarded-for $proxy _add_x_forwarded_for;
Proxy_set_header X-real-ip $remote _addr;

2. Modify the Tomcat configuration file

Modify in Server.xml

<valve classname= "Org.apache.catalina.valves.AccessLogValve" directory= "Logs"
prefix= "Localhost_access_log" suffix= ". txt"
pattern= "%{x-forwarded-for}i%l%u%t%r%s%b%d%q%{user-agent}i%t"

Resolvehosts= "false"/>
