haproxy在默认情况下不会记录日志(:(), 除了在haproxy.cfg里面的global段指定日志输出之外,还要配置系统的日志配置(rsyslog), 以Ubuntu14.4LTS为例:
1. vim /etc/haproxy/haproxy.conf
global log 127.0.0.1 local0 chroot /var/lib/haproxy
2. 在/etc/rsyslog.conf有以下的默认配置:
# # Where to place spool and state files # $WorkDirectory /var/spool/rsyslog # # Include all config files in /etc/rsyslog.d/ # $IncludeConfig /etc/rsyslog.d/*.conf
意思是会读取/etc/rsyslog.d下面的配置文件,现在为haproxy创建一个:/etc/rsyslog.d/haproxy.conf
vim /etc/rsyslog.d/haproxy.conf $ModLoad imudp $UDPServerRun 514 local0.* /var/log/haproxy.log
3. 重启rsyslog和haproxy
