haproxy后端为nginx时原ip地址透传

nginx操作

1.首先对nginx的主配置中的日志做修改

[root@nginx ~]# vim /apps/nginx/conf/nginx.conf

    log_format access_json '{"@timestamp":"$time_iso8601",'
        '"host":"$server_addr",'
        '"clientip":"$remote_addr",'
        '"size":$body_bytes_sent,'
        '"responsetime":$request_time,'
        '"upstreamtime":"$upstream_response_time",'
        '"upstreamhost":"$upstream_addr",'
        '"http_host":"$host",'
        '"uri":"$uri",'
        '"domain":"$host",'
        '"xff":"$http_x_forwarded_for",'        
        '"referer":"$http_referer",'
        '"tcp_xff":"$proxy_protocol_addr",'     
        '"http_user_agent":"$http_user_agent",'
        '"status":"$status"}';

2.在server段配置文件中调用此日志格式

[root@nginx ~]# vim /apps/nginx/conf/servers/mylinuxops.conf server {
        server_name www.mylinuxops.com;
        listen 80;
        access_log  /apps/nginx/logs/mylinuxops.log  access_json;
        location / {
                root /data/www;
                index index.html;
        }
}

配置HAProxy(http透传)

未使用http透传前

[root@nginx ~]# tail /apps/nginx/logs/mylinuxops.log 
{"@timestamp":"2019-06-04T16:30:47+08:00",   "host":"192.168.27.21",   "clientip":"172.20.27.10",   "size":19,   "responsetime":0.000,   "upstreamtime":"-",   "upstreamhost":"-",   "http_host":"www.mylinuxops.com",   "uri":"/index.html",   "domain":"www.mylinuxops.com",   "xff":"-",   "referer":"-",   "tcp_xff":"",   "http_user_agent":"curl/7.29.0",   "status":"200"}#xff显示为"-"

修改HAProxy配置文件，使用http模式下的ip透传

[root@haproxy ~]# vim /etc/haproxy/haproxy.cfg 
listen web bind 172.20.27.20:80
 mode http              #模式改为http
 option forwardfor      #开启forwardfor选项
 server web1 www.mylinuxops.com:80 check inter 3000 fall3 rise 5

测试
使用客户端访问

[root@client ~]# curl www.mylinuxops.comwww.mylinuxops.com

查看nginx上的日志

[root@nginx ~]# tail -f /apps/nginx/logs/mylinuxops.log 
{"@timestamp":"2019-06-04T17:29:22+08:00",   "host":"192.168.27.21",   "clientip":"192.168.27.10",   "size":19,   "responsetime":0.000,   "upstreamtime":"-",   "upstreamhost":"-",   "http_host":"www.mylinuxops.com",   "uri":"/index.html",   "domain":"www.mylinuxops.com",   "xff":"172.20.27.10",   "referer":"-",   "tcp_xff":"",   "http_user_agent":"curl/7.29.0",   "status":"200"}#"xff":"172.20.27.10" 客户端的地址被透传过来了

配置HAProxy(tcp透传)

1.修改HAProxy配置文件

[root@haproxy ~]# vim /etc/haproxy/haproxy.cfg listen web bind 172.20.27.20:80
 mode tcp               #将mode改为tcp
 option forwardfor      #开启forwardfor选项
 server web1 www.mylinuxops.com:80 send-proxy check inter 3000 fall 3 rise 5                    #在定义后端服务时加上 send-proxy参数。

2.修改nginx的配置文件

[root@nginx ~]# vim /apps/nginx/conf/servers/mylinuxops.conf 
server {
        server_name www.mylinuxops.com;
        listen 80 proxy_protocol;       #在listen选项后添加proxy_protocol选项
        access_log  /apps/nginx/logs/mylinuxops.log  access_json;
        location / {
                root /data/www;
                index index.html;
        }
}

测试
使用客户端访问

[root@client ~]# curl www.mylinuxops.comwww.mylinuxops.com

在nginx上查看日志

[root@nginx ~]# tail -f /apps/nginx/logs/mylinuxops.log 
{"@timestamp":"2019-06-04T17:43:57+08:00",   "host":"192.168.27.21",   "clientip":"192.168.27.10",   "size":19,   "responsetime":0.000,   "upstreamtime":"-",   "upstreamhost":"-",   "http_host":"www.mylinuxops.com",   "uri":"/index.html",   "domain":"www.mylinuxops.com",   "xff":"-",   "referer":"-",   "tcp_xff":"172.20.27.10",   "http_user_agent":"curl/7.29.0",   "status":"200"}#"tcp_xff":"172.20.27.10"  客户端的地址在tcp的模式下被
