mysql - 未能找到有效的数据目录。MySQL 通用二进制安装

问题描述

我打算将mysql安装到linux服务器。但是我没有对该服务器的root访问权限。所以我创建了两个文件夹，分别是 mysql 和 mysqldata。mysql 文件夹包含二进制文件。mysqldata 文件夹保存数据和日志。

我的.cnf

[mysqld]
user                    = mysql
port                    = 3306
bind-address            = localhost
basedir                 = /home/nwn/mysql/mysql-8.0
socket                  = /home/nwn/mysqldata/instA/socket/mysql.sock
datadir                 = /home/nwn/mysqldata/instA/data
tmpdir                  = /home/nwn/mysqldata/instA/tmp
secure_file_priv        = /home/nwn/mysqldata/instA/mysql-files
max_connections         = 150

# Logging
log-bin                 = /home/nwn/mysqldata/instA/logs/instA-binlog
log-error               = /home/nwn/mysqldata/instA/logs/instA-errorlog.err
slow_query_log          = 1
slow_query_log_file     = /home/nwn/mysqldata/instA/logs/instA-slowquery.log
long_query_time         = 0.5

# InnoDB
innodb_data_home_dir    = /home/nwn/mysqldata/instA/innodb/data
innodb_data_file_path   = ibdata1:50M;ibdata2:12M:autoextend:max:500M
innodb_log_group_home_dir = /home/nwn/mysqldata/instA/innodb/log
innodb_buffer_pool_size = 32M

# MyISAM
key_buffer_size         = 16M

server_id                = 1

我做了所有其他配置。当我运行以下命令时

mysql-8.0]$ bin/mysqld --defaults-file=~/mysqldata/instA/my.cnf --initialize-insercure

我在 error_log 中有以下日志

 cat ~/mysqldata/instA/logs/instA-errorlog.err

解决方案

尽管帖子很旧，但发布我的解决方案，因为我花了大约 2 个小时才弄清楚，这可以帮助别人节省时间。

您可以尝试这样做：

shell> mysqld --initialize

这将初始化您安装 MySql 服务器的路径中的数据目录。一般放在C:\Program Files\MySQL\MySQL Server 8.0。

希望它可以帮助某人。
