/var/log/keepalived/*.log { #切分的兩個文件名
daily #按天切分
rotate 7 #保留7份
create 0644 haproxy haproxy #創建新文件的權限、用戶、用戶組
compress #壓縮舊日志
delaycompress #延遲一天壓縮
missingok #忽略文件不存在的錯誤
dateext #舊日志加上日志后綴
sharedscripts #切分后的重啟腳本只運行一次
postrotate #切分后運行腳本重載rsyslog，讓rsyslog向新的日志文件中輸出日志
/bin/kill -HUP $(/bin/cat /var/run/syslogd.pid 2>/dev/null) &>/dev/null
