v2ray-core: v2ray does not read config.json from a custom path and not from a symlink either

What version of V2Ray are you using?

5.1.0

What’s your scenario of using V2Ray?

I’ve installed v2ray by using the fhs script. Initially I tried to create a symlink to /custom/path/to/config.json from /usr/local/etc/v2ray/config.json, but that didn’t work. Then I’ve created a override.conf inside the v2ray.service.d directory with below content:

[Service]
User=v2ray_user
ExecStart=
ExecStart=/usr/local/bin/v2ray run -config /custom/path/to/config.json

At first, tried without User=v2ray_user directive but didn’t work. So I created a new linux user, ran chown v2ray_user:v2ray_user config.json. But still I get permission denied:

Failed to start: main/commands: failed to load config: [/custom/path/to/config.json] > fail to load /custom/path/to/config.json: open /custom/path/to/config.json: permission denied

Had the same error with symlinks too. But interestingly, it works if I run v2ray run -config /custom/path/to/config.json in terminal or when I use User=my_own_username directive inside the override.conf

What problems have you encountered?

See above.

What’s your expectation?

I expect to be able to change to a custom path to config.json using symlinks or a .conf drop-in file.

How can one customize the path for config.json file?

If you don’t want to compromise the permissions of your home directory, you can use file ACL. No workaround is needed.

setfacl -m u:v2ray_user:rx <path to file or directory>

Apply this command to all parent directory of config.json. It is safe and does not affect the permissions of other users.

Works fine here. You might have wrong permission for your config file.

You must create a new problem. May you should write a golang program to have a test?

Change your original file to 777

I did, it didn’t solve the issue. I even previously tried to create a new user and set ownership of the file to that user but that didn’t work either.

also needs to change the permission of the directory where the file is located to 755.

All the parent directories of my custom config.json file are set to 755 up to the user home directory.
