mysql安装无法创建mysqld_MySQL 5.7安装错误`mysqld：无法创建/写入文件’/ var / lib / mysql / is_writable’...

我想在Ubuntu 14.04上安装

MySQL 5.7.

以下是我遵循的步骤：

rm -rf /var/lib/mysql

mkdir -p /var/lib/mysql

cd

wget http://dev.mysql.com/get/mysql-apt-config_0.7.2-1_all.deb

dpkg -i mysql-apt-config_0.7.2-1_all.deb

apt-get update

apt-get -y install mysql-server

除最后一步外,所有步骤都完美无缺.它给了我以下错误：

mysqld: Can't create/write to file '/var/lib/mysql/is_writable' (Errcode: 13 - Permission denied)

2016-05-10T02:10:24.219279Z 0 [ERROR] --initialize specified but the data directory exists and is not writable. Aborting.

2016-05-10T02:10:24.219530Z 0 [ERROR] Aborting
