nginx啓用stream日誌配置文件

 

主配置文件/etc/nginx/nginx.conf增長內容：

stream {


    log_format proxy '$remote_addr [$time_local] '
                 '$protocol $status $bytes_sent $bytes_received '
                 '$session_time "$upstream_addr" '
                 '"$upstream_bytes_sent" "$upstream_bytes_received" "$upstream_connect_time"';

    access_log /var/log/nginx/tcp-access.log proxy ;
    open_log_file_cache off;
    include /etc/nginx/conf.d/*.stream;
}

具體的tcp.stream配置文件

 upstream TCP59001 {
        hash $remote_addr consistent;
        server 192.168.1.176:59001;
    }
        server {
        listen 59001;
        proxy_connect_timeout 5s;
        proxy_timeout 30s;
        proxy_pass TCP59001;
    }

nginx重讀配置並檢查tcp session日誌的生成

nginx重讀配置

nginx -s reload

檢查日誌

tail /var/log/nginx/tcp-access.log

192.168.3.218 [25/Apr/2017:17:55:57 +0800] TCP 200 103 122 10.671 "192.168.1.176:59001" "122" "103" "0.000"

192.168.9.1 [25/Apr/2017:18:54:55 +0800] TCP 200 359 374 334.827 "192.168.1.176:59001" "374" "359" "0.001"

至此配置已經完成，upstream的日誌已經順利記錄到文件。

配置經驗

• 測試發現nginx會等待session結束纔會記錄到日誌文件；
• session日誌只是tcp層面的記錄，包括session時間，發送接收字節數等等；
• session內部發送日誌(好比一個socket鏈接創建起來之後，屢次發送心跳數據）須要在應用層面才能記錄；
