安装
yum install -y gcc openssl-devel popt-devel ipvsadm libnl3-devel net-snmp-devel libnl libnl-devel libnfnetlink-devel
tar -zxvf keepalived-2.2.4.tar.gz
cd keepalived-2.2.4
./configure --prefix=/usr/local/keepalived-2.2.4
mkdir /etc/keepalived/
cp /usr/local/keepalived-2.2.4/etc/keepalived/keepalived.conf /etc/keepalived/

剥离日志出来
mkdir /var/log/keepalived/
vim /etc/sysconfig/keepalived
KEEPALIVED_OPTIONS="-D -d -S 0"
vim /etc/rsyslog.conf
local0.* /var/log/keepalived/keepalived.log
systemctl restart rsyslog
vim /etc/systemd/system/keepalived.service
EnvironmentFile=/etc/sysconfig/keepalived
systemctl daemon-reload
systemctl start keepalived.service
配置日志轮转
vim /etc/logrotate.d/keepalived
/var/log/keepalived/*.log {
su root root
daily
rotate 7
create 0600 root root
compress
delaycompress
missingok
dateext
sharedscripts
postrotate
/bin/kill -HUP $(/bin/cat /var/run/syslogd.pid 2>/dev/null) &>/dev/null
endscript
}
测试强制轮询
/usr/sbin/logrotate -vf /etc/logrotate.d/keepalived
crontab -e #添加以下代码
0 0 * * * /usr/sbin/logrotate -vf /etc/logrotate.d/keepalived #每天凌晨定时执行脚本
