无法在 Onion Omega IoT 板上安装 mysql

问题描述

我正在我的 Onion Omega2+ IoT 板上安装 MysqL。命令'opkg update && opkg install mariadb-client mariadb-server'安装MysqL，然后我通过shell运行命令MysqL，出现如下错误： 'MysqLd: datadir '/mnt/data/MysqL/' in '/etc/MysqL/my.cnf' 不存在'。 没有像 /mnt/data/MysqL/ 这样的目录，我改变了它。然后我通过终端运行命令 MysqL，它给出错误：ERROR 2002 (HY000): Can't connect to local MysqL server through socket '/var/run/MysqLd/MysqLd.sock' (2 "No such file or directory" ）。我检查了目录 /var/run/MysqLd/MysqLd.sock 不存在，所以我也按照 error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)' -- Missing /var/run/mysqld/mysqld.sock 创建了它 我检查了 /etc/MysqL/my.conf 文件并重新运行 'MysqL'，最后出现这个错误 ERROR 2002 (HY000)：无法通过套接字'/var/run/MysqLd/MysqLd.sock'连接到本地MysqL服务器（146“锁定超时；重试事务”） 我只在MysqL错误页面上发现这个错误，找不到原因，请帮忙 （也许有用：/var 目录实际上是 /tmp 的链接，还有另一个套接字文件 /var/run/ubus.sock，所以我也尝试在该目录中创建套接字文件，结果相同）

我的 my.cnf 文件看起来像：

[client]
port        = 3306
socket      = /var/run/MysqLd/MysqLd.sock

[MysqLd]
user        = mariadb

port        = 3306

# figure out where you are going to put the databases
# And run MysqL_install_db --force

######### This should also not go on the NAND #######
