【Haproxy】開啟日誌記錄

至於為什麽開啟日誌記錄，即使我不說，你們這群老司機也懂。
開啟日誌分割，主要涉及到兩個知識點：
①HAproxy關於日誌記錄的配置
②Rsyslog的配置
環境：
CentOS6.5
haproxy-1.6.11
配置日誌記錄的前提是HAproxy可以正常使用，操作者熟悉Haproxy的配置文件
配置HAproxy的日誌記錄選項
[[email protected] haproxy]# vim /etc/haproxy/haproxy.cfg
defaults
log global ##開啟全局日誌，對所有池子生效
log 127.0.0.1:514 local3 ##將3級別日誌信息發送到本機514端口的rsyslog程序
:wq!創建Haproxy日誌存儲的文件
[[email protected] haproxy]# mkdir -p /var/log/haproxy/ [[email protected] haproxy]# touch /var/log/haproxy/haproxy.log
配置Rsyslog配置，開啟514端口的偵聽
[[email protected] haproxy]# vim /etc/rsyslog.conf
$ModLoad imudp #默認是註釋，將註釋去掉
$UDPServerRun 514 #默認是註釋，將註釋去掉
local3.* /var/log/haproxy/haproxy.log ##添加一行該信息，該信息的local3要和ha裏面的相對應
##後面的便是你希望haproxy的日誌存儲到哪裏，指定文件檢查rsyslog是否開啟監聽
[[email protected] haproxy]# netstat -tunlp|grep 514 udp 0 0 0.0.0.0:514 0.0.0.0:* 2615/rsyslogd udp 0 0 :::514 :::* 2615/rsyslogd
重啟兩個服務服務
[[email protected] haproxy]# service rsyslog restart Shutting down system logger: [ OK ] Starting system logger: [ OK ] [[email protected] haproxy]# service haproxy restart Shutting down haproxy: [ OK ] Starting haproxy: [ OK ]
測試日誌是否開始記錄
[[email protected] haproxy]# tail -f /var/log/haproxy/haproxy.log Sep 26 10:56:40 localhost haproxy[2561]: Stopping proxy stats in 0 ms. Sep 26 10:56:40 localhost haproxy[2561]: Stopping frontend dev_posp in 0 ms. Sep 26 10:56:40 localhost haproxy[2561]: Stopping backend dev_posp in 0 ms. Sep 26 10:56:40 localhost haproxy[2561]: Proxy stats stopped (FE: 0 conns, BE: 0 conns). Sep 26 10:56:40 localhost haproxy[2561]: Proxy dev_posp stopped (FE: 6 conns, BE: 0 conns). Sep 26 10:56:40 localhost haproxy[2561]: Proxy dev_posp stopped (FE: 0 conns, BE: 6 conns). Sep 26 10:56:40 localhost haproxy[2635]: Proxy stats started. Sep 26 10:56:40 localhost haproxy[2635]: Proxy dev_posp started. Sep 26 10:56:40 localhost haproxy[2635]: Proxy dev_posp started. Sep 26 10:57:01 localhost haproxy[2636]: Connect from 192.168.222.1:57057 to 192.168.222.130:80 (dev_posp/TCP) Sep 26 10:57:01 localhost haproxy[2636]: Connect from 192.168.222.1:57058 to 192.168.222.130:80 (dev_posp/TCP)
技巧根據不同的需求來打印不同的日誌級別
日誌級別有local0~local7
#define KERN_EMERG "<0>" /* system is unusable */
#define KERN_ALERT "<1>" /* action must be taken immediately */
#define KERN_CRIT "<2>" /* critical conditions */
#define KERN_ERR "<3>" /* error conditions */
#define KERN_WARNING "<4>" /* warning conditions */
#define KERN_NOTICE "<5>" /* normal but significant condition */
#define KERN_INFO "<6>" /* informational */
#define KERN_DEBUG "<7>" /* debug-level messages */本文出自 “小小小平凡” 博客，謝絕轉載！
