上次的错误依照各位的帮助，安装了libaio-dev_0.3.106，libaio1_0.3.106两个包（libaio-dev依赖libaio1，无网真是麻烦）。执行service mysql start错误依旧，但是查看err。各位再帮得看看

还有一个问题，就是在配置的时候sudo /usr/local/mysql/scripts/mysql_install_db --user=mysql --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data

这个user=mysql,mysql是自己创建的用户？？我改为别的用户名可以么？

装mysql直接
sudo apt-get install -y mysql-server
