Executing scripts after Linux is fully booted?

Question

linux

The task is to automatically mount the ftp folder at system startup
There is a script that mounts the ftp folder
#!/bin/bash
#HOST=
#FOLDER=
curlftpfs $HOST/$FOLDER /mnt/ftp -o allow_other,codepage=windows-1251[,iocharset= utf8] 2>>/adminfolder/log/error.log
exit 0
Script added to crontab
@reboot root /adminfolder/scripts/ftp_conn.sh #Execute after restart
Question: How can I force the script to be executed only after the network is fully loaded? Or maybe there is another option to mount ftp after a system restart. (There is an option with adding a line to /etc/fstab)
With these parameters in crontab, network-related errors in the log:
Error connecting to ftp: Could not resolve host: @[email protected]; Unknown error
Error connecting to ftp: Failed to connect to @[email protected]: Network is unreachable
CentOS 7.3 system
PS
There is an option to add a line to /etc/fstab
curlftpfs# ftp://ftp.host.ru/folder/ /mnt/ftp fuse rw,nosuid,nodev,allow_other,codepage=windows-1251[,iocharset=utf8] 0 0
This option does not suit and it did not work, although the mount -a command is executed normally, but after restarting the system swears at fstab
Thanks in advance for the advice !

Answer 1

Write a systemd script in which to prescribe the necessary requirements in After ??

Answer 2

well, in general, the line for fstab is something like this
curlftpfs# ftp://{user}:{password}@{ server address}/{folder}/ {path to the mount point} fuse rw,allow_other,noauto,user 0 0,
respectively, should be fuse
modprobe fuse
This is the correct way to mount after boot.
Otherwise, write a script and add it to the init part as a service.

Answer 3

I'll answer my own question!
All the proposed options above are not suitable for a more or less correct implementation of the task.
I had to read about systemd again, after that a unit was created and a script for connecting and mounting ftp was written.
Parameters were specified in the unit
In the [Unit] section we specify that the script should be launched only after the network is started After=network.target
In the [Service] section we specify the oneshot type and add the path to our script ExecStart=/usr/bin/sh /adminfolder/scripts /conn_ftp1.sh), I also specified a parameter so that systemd would not consider that the service is down RemainAfterExit=yes
And in the [Install] section, specify multi-user.target
After that, we add it to auto start and start, check that our unit is working and started without errors systemctl status nameservice.service
