映射不同端口
server
{
listen 80;
server_name xxx123.tk;
location / {
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://192.168.10.38:3000;
}
access_log logs/xxx123.tk_access.log;
}
server
{
listen 80;
server_name xxx456.tk;
location / {
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://192.168.10.40:80;
}
access_log logs/xxx456.tk_access.log;
}
负载均衡
upstream monitor_server {
server 192.168.0.131:80;
server 192.168.0.132:80;
}
server
{
listen 80;
server_name nagios.xxx123.tk;
location / {
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://monitor_server;
}
access_log logs/nagios.xxx123.tk_access.log;
}
真实ip地址
log_format access '$HTTP_X_REAL_IP - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $HTTP_X_Forwarded_For';
access_log logs/access.log access;
