未能找到有效的数据目录.MySQL通用二进制安装 [英] Failed to find valid data directory. MySQL generic binary installion
问题描述
我要安装 mysql 到 linux 服务器.但我没有该服务器的 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.
Im going to install mysql to linux server. But I dont have root access to that server. So I created two folders called mysql and mysqldata. mysql folder holds binary files. mysqldata folder holds data and the logs.
[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
I did all the other configurations. when I run following command
mysql-8.0]$ bin/mysqld --defaults-file=~/mysqldata/instA/my.cnf --initialize-insercure
我在 error_log 中有以下日志
I have following logs in the error_log
cat ~/mysqldata/instA/logs/instA-errorlog.err

推荐答案
尽管帖子很旧,但发布我的解决方案,因为我花了大约 2 个小时才弄明白,这可以帮助某人节省时间.
Even though the post is very old, but posting my solution as it took me around 2 hours to figure it out and this can help someone save that time.
你可以试试:
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.
This shall initialse the data directory in the path where you have installed MySql server. Generally placed at C:\Program Files\MySQL\MySQL Server 8.0.
希望对某人有所帮助.
