我尝试在没有root权限的情况下在redhat服务器上安装MySQL 5.7。我下载了源代码，并且编译和安装顺利。但是当我运行mysqld时，它总是会弹出错误。
我按照说明进行操作 http://www.martijn-onderwater.nl/2010/11/23/installing-mysql-on-linux-without-root-privileges/
我创建了一个my.cnf文件
[mysqld]
port=3306
socket=/afs/crc.nd.edu/user/j/jlai1/MySQL/thesock
basedir=/afs/crc.nd.edu/user/j/jlai1/MySQL
datadir=data
pid-file=$HOME/MySQL/mysql.pid
user=root
[client]
port=3306
socket=$MySQL_HOME/thesock
user=root
[mysqladmin]
socket=$MySQL_HOME/thesock
user=root
当我运行./bin/mysqld --defaults-file = my.cnf --initialize时，它运行正常。但是我遇到了以下问题
./bin/mysqld --defaults-file=my.cnf

问题似乎是您的用户没有绑定端口的权限，3306专门用于Mysql。
