Having a pretty tough time getting WordPress to recognize my SSH keys. I know that the keys themselves work, because I use them to SSH into the server myself. Despite going over this tutorial repeatedly, as well as some other ServerFault answers that I'll reference below, I can't seem to figure it out.
I'm using Ubuntu 16.04 and Apache. I have a non-root user with sudo permissions, named 'jake'.
The permissions over /home/jake/.ssh are as follows:
drwx------ 2 jake jake 4096 Aug 12 23:42 ./ drwxr-xr-x 5 jake jake 4096 Aug 10 13:20 ../ -rw-r--r-- 1 jake jake 743 Aug 12 16:21 authorized_keys -rw------- 1 jake jake 3247 Aug 10 13:58 id_rsa -rw------- 1 jake jake 743 Aug 10 13:58 id_rsa.pub -rw-r--r-- 1 jake jake 222 Aug 12 23:42 known_hosts
Which I believe matches the guide, which says to use chmod 700 on the .ssh directory, and 0644 on authorized_keys. I skipped the step of restricting the key to only be used by 127.0.0.1, because I am using that key to SSH into the server.
At the end of /var/www/html/wp-config.php, I have the lines specified by the tutorial:
define('FS_METHOD', 'ssh2'); define('FTP_PUBKEY','/home/jake/.ssh/id_rsa.pub'); define('FTP_PRIKEY','/home/jake/.ssh/id_rsa'); define('FTP_USER','jake'); define('FTP_PASS',''); define('FTP_HOST','127.0.0.1:22');
The tutorial does have some advice at the bottom, with things such as checking the permissions - but I did, and I don't personally see anything wrong, although I'm certainly no Linux expert. In addition, I tried researching other answers - this user is on CentOS with Nginx, so I'm not sure how relevant it is, but the accepted answer is to have the web server own the id_rsa and id_rsa.pub files - when I tried doing
chown www-data:www-data id_rsa (and id_rsa.pub), it didn't make a difference. This other question doesn't have an accepted answer, but the only answer with an upvote says to run
chmod g-r wp_rsa, but that also didn't make a difference.
