  <p>I tried to download and install MySQL 5.7.10, but it shows me errors regarding to InnoDB setup as below:</p>
  
  <pre><code>[hoge@blackett mysql]$ ./bin/mysqld --initialize --basedir=/home/hoge/mysql --character-set-server=utf8

  </code></pre>
  
  <p>I also did the following:</p>
  
  <pre><code>cp ./support-files/my-default.cnf ~/my.cnf
  </code></pre>
  
  <p>I tried the following command, but it gives me the same errors:</p>
  
  <pre><code>[hoge@blackett mysql]$ ./bin/mysqld --initialize --character-set-server=utf8 --basedir=/home/hoge/mysql --defaults-file=/home/hoge/my.cnf
  </code></pre>
  
  <p>I wrote the following in my.cnf, but doesn't solve the error:</p>
  
  <pre><code>innodb_use_native_aio = 0
  </code></pre>
  
  <p>I have no ideas to solve them.
  Could you please help me?</p>
