keepalived+nginx双机热备无法执行脚本，踩坑含泪总结！（centos7）

1、关闭selinux（最坑之一）

setenforce 0

永久关闭selinux

sed -i "s/^SELINUX=.*/SELINUX=disabled/g" /etc/selinux/config

重启keepalived

systemctl restart keepalived

2、关闭防火墙

systemctl stop firewalled

禁止开机启动:systemctl disable firewalled

3、修改keepalived打印日志路径

vim /etc/sysconfig/keepalived,将KEEPALIVED_OPTION = "-D"改为"-D -d -S 0"

vim /etc/rsyslog.conf

添加：local0.* /var/log/keepalived.log

systemctl restart rsyslog

systemctl restart keepalived

4、执行脚本授权 chmod 765 xx.sh
