vagrant /多個實例mysqld

Question

所以我試圖設置一個vagrant precise64盒子，其中包含多個mysqld實例，這些實例都在不同的端口上監聽並使用不同的套接字文件。

我的CNF文件是在這裏與我相信這是正確的所有權和權限

vagrant@mysqld:~$ sudo ls -la /home/mysql/user.cnf 
-rw-r--r-- 1 mysql mysql 3562 Oct 30 13:26 /home/mysql/user.cnf 

但是當我嘗試啓動我的mysqld的情況下，我得到

vagrant@mysqld:~$ sudo mysqld_safe --defaults-file=/home/mysql/user.cnf --user=mysql & 
[1] 11624 
vagrant@mysqld:~$ 151030 16:07:33 mysqld_safe Can't log to error log and syslog at the same time. Remove all --log-error configuration options for --syslog to take effect. 
151030 16:07:33 mysqld_safe Logging to '/var/log/mysql/error.log'. 
151030 16:07:33 mysqld_safe Starting mysqld daemon with databases from /var/lib/dbs/user/mysql/data 
151030 16:07:33 mysqld_safe mysqld from pid file /var/lib/dbs/user/mysql/mysqld_user.pid ended 

，如果我看error.log我看到它抱怨它無法打開文件。

151030 16:07:33 mysqld_safe Starting mysqld daemon with databases from /var/lib/dbs/user/mysql/data 
Could not open required defaults file: /home/mysql/user.cnf 
Fatal error in defaults handling. Program aborted 
151030 16:07:33 mysqld_safe mysqld from pid file /var/lib/dbs/user/mysql/mysqld_user.pid ended 

有沒有人有什麼想法？我已經燒了太多時間了。

這裏是我的CNF文件

# 
# The MySQL database server configuration file.

# You can copy this to one of: 
# - "/etc/mysql/my.cnf" to set global options, 
# - "~/.my.cnf" to set user-specific options.

# One can use all long options that the program supports. 
# Run program with --help to get a list of available options and with 
# --print-defaults to see which it would actually understand and use.

也許遠投中的內容，但如何試圖打開的/ home/mysql目錄世界閱讀？ chmod o+x /home/mysql進行測試？
