前言

環(huán)境：centos 7.9 keepalived-2.2.7

keepalived默認(rèn)日志路徑

默認(rèn)情況下，不管yum安裝的keepalived還是源碼編譯安裝的keepalived，其都是受systemd管理的，所以日志可以這樣看：

 systemctl  status keepalived.service -l
 journalctl  -u keepalived.service  -f
 tail -22f /var/log/messages | grep Keepalived

修改keepalived日志路徑

默認(rèn)的日志路徑太不友好，可以讓keepalived單獨(dú)輸出日志到指定文件，如下配置：

keepalived的環(huán)境變量配置默認(rèn)在 yum 安裝的在 /etc/sysconfig/keepalived ，源碼編譯安裝的在/usr/local/keepalived/etc/sysconfig/keepalived文章來源地址http://www.zghlxwxcb.cn/news/detail-671710.html

[root@node2 ~]# vim /usr/local/keepalived/etc/sysconfig/keepalived 
# Options for keepalived. See `keepalived --help' output and keepalived(8) and
# keepalived.conf(5) man pages for a list of all options. Here are the most
# common ones :
#
# --vrrp               -P    Only run with VRRP subsystem.
# --check              -C    Only run with Health-checker subsystem.
# --dont-release-vrrp  -V    Dont remove VRRP VIPs & VROUTEs on daemon stop.
# --dont-release-ipvs  -I    Dont remove IPVS topology on daemon stop.
# --dump-conf          -d    Dump the configuration data.
# --log-detail         -D    Detailed log messages.
# --log-facility       -S    0-7 Set local syslog facility (default=LOG_DAEMON)

 KEEPALIVED_OPTIONS="-D -S 0"		#改這一句，添加-S 0

[root@node2 ~]#  vim /etc/rsyslog.conf 
#在下面這一行后面添加
# Save boot messages also to boot.log
local7.*                                                /var/log/boot.log
