前言
环境:centos 7.9 keepalived-2.2.7
keepalived默认日志路径
默认情况下,不管yum
安装的keepalived
还是源码编译安装的keepalived
,其都是受systemd
管理的,所以日志可以这样看:
systemctl status keepalived.service -l
journalctl -u keepalived.service -f
tail -22f /var/log/messages | grep Keepalived
修改keepalived日志路径
默认的日志路径太不友好,可以让keepalived单独输出日志到指定文件,如下配置:文章来源:https://www.toymoban.com/news/detail-671710.html
keepalived的环境变量配置默认在 yum 安装的在 /etc/sysconfig/keepalived ,源码编译安装的在/usr/local/keepalived/etc/sysconfig/keepalived

[root@node2 ~]# vim /usr/local/keepalived/etc/sysconfig/keepalived
# Options for keepalived. See `keepalived --help' output and keepalived(8) and

#
KEEPALIVED_OPTIONS="-D -S 0" #改这一句,添加-S 0
[root@node2 ~]# vim /etc/rsyslog.conf
#在下面这一行后面添加
# Save boot messages also to boot.log
local7.* /var/log/boot.log
#添加这一行
# save keepalived log to keepalived.log
local0.* /var/log/keepalived.log
[root@node1 sysconfig]# systemctl restart rsyslog #重启rsyslog
[root@node1 sysconfig]# systemctl restart keepalived #重启keepalived
[root@node1 sysconfig]# tail -222f /var/log/keepalived.log #keepalived的日志已经成功指定到我们定义的文件了
