Question

如何在没有root权限/写入工具区访问权限的情况下启动mysql？我收到了以下错误

host13:~/JS> mysqld start

Answer 1

您可以将MySQL数据目录移动到您能够写入的位置，然后在/etc/my.cnf（或可能是其他位置，具体取决于您的系统默认值）中指定它，参数为datadir。

如果您的数据目录尚未初始化（在这种情况下mysqld会抱怨缺少权限表），您可以像这样创建它们：

mysql_install_db --datadir=$path_to_new_datadir

Answer 2

总结答案：

# Setup DB
mysql_install_db --datadir=<FULL PATH TO STORE DB FILES> 

# Start server
mysqld --datadir=<FULL PATH TO STORE DB FILES> 

# Shutdown server
mysqladmin -u root shutdown

注意：
1. =之后的datadir - 没有命令将失败
2.应使用完整路径

没有root权限的Mysql
