Copy the file whose path is /usr/local/keepalived-1.3.4/etc/sysconfig/keepalived to /etc/sysconfig/keepalived
cp /usr/local/keepavlied-1.3.4/etc/sysconfig/keepalived /etc/sysconfig/

Warning: ExecStart=/usr/sbin/keepalived $KEEPALIVED_OPTIONS (code=exited, status=203/EXEC)
Check that the ll /usr/sbin/keepalived file does not exist, there are two ways to solve it at this time
1. Copy a keepalived to /usr/sbin/
2. Modify the /lib/systemd/system/keepalived.service file, and change the /usr/sbin/ path to the path where we store the keepalived file
