linux – WordPress无法找到ssh公钥和私钥对

我正在使用Wordpress的插件安装程序的SSH2功能.

我已经安装了lib2ssh并且它正在工作(WordPress承认它存在).

我提供给wordpress的用户(称为playwithbits)是chrooted,其主目录为/ home / nginx / domains / playwithbits /

公钥和私钥位于/ home / nginx / domains / playwithbits / keys /目录中,分别命名为id_rsa.pub和id_rsa.

我已将id_rsa.pub的内容复制到位于/home/nginx/domains/playwithbits/.ssh/中的authorized_keys文件中

我没有为密钥文件设置密码.但是Wordpress不断返回错误：

Public and Private keys incorrect for playwithbits

我已向Wordpress提供以下信息

Hostname: localhost
Username: playwithbits
Password: Blank
Public key: /keys/id_rsa.pub //I have also tried the paths from server root
Private key: /keys/id_rsa

以下是我在相关文件夹和文件上设置的权限：

drwx------ 2 playwithbits playwithbits 4096 Jun  8 11:25 .ssh
drwx------ 2 playwithbits playwithbits 4096 Jun  8 13:27 keys
-rw------- 1 playwithbits playwithbits  414 Jun  8 11:21 authorized_keys
-rw------- 1 playwithbits playwithbits 1.7K Jun  6 02:17 id_rsa
-rw-r--r-- 1 playwithbits playwithbits  414 Jun  6 02:17 id_rsa.pub

我也试图在调试模式下连接,我得到以下输出：

有谁知道为什么我不能使用公钥和私钥访问？如果我使用帐户的密码,则wordpress可以登录并执行更新.

编辑：在我的sshd_config文件中,我有以下规则：

Match group web-root-locked
         ChrootDirectory /home/nginx/domains/%u
         X11Forwarding no
         AllowTcpForwarding no
         ForceCommand internal-sftp
         AuthorizedKeysFile /home/nginx/domains/%u/.ssh/authorized_keys

playwithbits是web-root-locked的成员
