[SOLVED] Composer for build PHP version

Hi guys!
I wonder if you have being able to use composer along with a PHP additional version build from source.
I did tried to add it to the jail but seems like /opt is not an allowed directory for jails in ispconfig.

Code:

Traceback (most recent call last):
  File "/usr/sbin/jk_init", line 247, in <module>
    main()
  File "/usr/sbin/jk_init", line 244, in main
    activateConfig(config, jail, args)
  File "/usr/sbin/jk_init", line 162, in activateConfig
    ji.handle_cfg_section(config,jail,cfg,section)
  File "/usr/sbin/jk_init", line 108, in handle_cfg_section
    self.didfiles = jk_lib.copy_binaries_and_libs(chroot, paths2, config['force'], config['verbose'], 1, try_hardlink=config['hardlink'],try_glob_matching=1,handledfiles=self.didfiles)
  File "/usr/share/jailkit/jk_lib.py", line 642, in copy_binaries_and_libs
    create_parent_path(chroot,os.path.dirname(file), be_verbose, copy_permissions=1, allow_suid=allow_suid, copy_ownership=retain_owner)
  File "/usr/share/jailkit/jk_lib.py", line 464, in create_parent_path
    os.mkdir(jailpath, 0755)
OSError: [Errno 13] Permission denied: '/var/www/clients/clientX/webY/opt'

Maybe build additional php versions on another directory like usr?
Ideas?

Best regards.

 

TBH, I was aware that web root is protected, but not sure how.
Is this on the manual or somewhere more detailed?

Update: Found it around page 230, thanks.

 

Thanks!
That worked, now I have some other issues related to symfony and composer, but linking a php build to jails worked!
