haproxy软件日志输出到指定文件

默认haproxy的日志是输出到系统syslog中，查看起来不是非常方便，为了更好的管理haproxy的日志，我们在生产环境中一般单独定义出来。需要将haproxy的info及notice日志分别记录到不同的日志文件中。

需要修改rsyslog配置，为了便于管理。

将haproxy相关的配置独立定义到haproxy.conf，并放到/etc/rsyslog.d/下，rsyslog启动时会自动加载此目录下的所有配置文件。

默认的haproxy的配置文件

如下

#---------------------------------------------------------------------
# Example configuration for a possible web application.  See the
# full configuration options online.

# Global settings
#---------------------------------------------------------------------
global
    # to have these messages end up in /var/log/haproxy.log you will
    # need to:
    #
    # 1) configure syslog to accept network log events.  This is done
    #    by adding the '-r' option to the SYSLOGD_OPTIONS in
    #    /etc/sysconfig/syslog
    #
    # 2) configure local2 events to go to the /var/log/haproxy.log
    #   file. A line like the following can be added to
    #   /etc/sysconfig/syslog
    #
    #    local2.*                       /var/log/haproxy.log
    #
    log         127.0.0.1 local2 info

    chroot      /var/lib/haproxy
    pidfile     /var/run/haproxy.pid
    maxconn     40000
    user        haproxy
    group       haproxy
    daemon

    # turn on stats Unix socket
    stats socket /var/lib/haproxy/stats

#    server  app4 127.0.0.1:5004 check

其中日志的配置文件有关日志的配置是 log 127.0.0.1 local2 info

为了便于管理将haproxy相关的配置独立定义到haproxy.conf

配置方式

1.编辑“/etc/sysconfig/rsyslog”文件

将如下配置增加 -r 参数：

SYSLOGD_OPTIONS=""
改成
SYSLOGD_OPTIONS="-r"

2.编辑“/etc/rsyslog.c编程onf”取消红框部分内容的注释

并在“local7.*”前面插入一行：

local2.*                /var/log/haproxy/haproxy.log

3.重启服务

重启 rsyslog

systemctl restart rsyslog
