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

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：
|
1 2 3 |
SYSLOGD_OPTIONS="" 改成 SYSLOGD_OPTIONS="-r" |
2.编辑“/etc/rsyslog.conf”取消红框部分内容的注释
并在“local7.*”前面插入一行：
|
1 |
local2.* /var/log/haproxy/haproxy.log |
3.重启服务
重启 rsyslog
|
1 |
systemctl restart rsyslog |
