至于为什么开启日志记录,即使我不说,你们这群老司机也懂。
开启日志分割,主要涉及到两个知识点:
①HAproxy关于日志记录的配置
②Rsyslog的配置
环境:
CentOS6.5
haproxy-1.6.11
配置日志记录的前提是HAproxy可以正常使用,操作者熟悉Haproxy的配置文件
配置HAproxy的日志记录选项
[root@node1 haproxy]# vim /etc/haproxy/haproxy.cfg defaults log global ##开启全局日志,对所有池子生效 log 127.0.0.1:514 local3 ##将3级别日志信息发送到本机514端口的rsyslog程序 :wq!
创建Haproxy日志存储的文件
[root@node1 haproxy]# mkdir -p /var/log/haproxy/ [root@node1 haproxy]# touch /var/log/haproxy/haproxy.log
配置Rsyslog配置,开启514端口的侦听
[root@node1 haproxy]# vim /etc/rsyslog.conf $ModLoad imudp #默认是注释,将注释去掉 $UDPServerRun 514 #默认是注释,将注释去掉 local3.* /var/log/haproxy/haproxy.log ##添加一行该信息,该信息的local3要和ha里面的相对应 ##后面的便是你希望haproxy的日志存储到哪里,指定文件
检查rsyslog是否开启监听
[root@node1 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
重启两个服务服务
[root@node1 haproxy]# service rsyslog restart Shutting down system logger: [ OK ] Starting system logger: [ OK ] [root@node1 haproxy]# service haproxy restart Shutting down haproxy: [ OK ] Starting haproxy: [ OK ]
测试日志是否开始记录
[root@node1 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)
技巧根据不同的需求来打印不同的日志级别
日志级别有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 */
