Please run mysql_upgrade to create it.

mysql_upgrade 好像是只有数据库启动后才能执行吧，把 plugin，host 表从别的库拷过来扔到数据目录，权限改正确，启动一下试试。

再不行就把 mysql 这个库的所有表都拷过来。记得好像是个 bug，数据目录本身是存在这个表的，但就是读不到。。。。启动成功后 drop 掉，再执行建表语句创建（ mysql 安装文件中有这几个语句）

服务器内存够不够。以前碰到这种，用的 docker

monkeydev

2020-09-08 08:39:08 +08:00

root@ubuntu:~# mysql_upgrade

Command 'mysql_upgrade' not found, but can be installed with:

apt install mysql-server-core-5.7
apt install mariadb-server-core-10.1
apt install percona-server-server-5.6
apt install percona-xtradb-cluster-server-5.7

--pid-file 制定的文件的路径中的位置是所有操作系统用户都可以访问的。考虑选择一个不同的目录

文件权限问题方向看看

@monkeydev 从错误的路径看看样子你根本不是用 apt-get 安装的数据库你很可能用的一键包啥的

不是 apt-get 安装的 mysql 的命令很可能不在默认 PATH 里你可以试试 /www/server/mysql/bin/mysql_upgrade

加一个 skip-grant-tables 重启一下，先把 mysql 启动起来，再把数据备份了，再重新初始化一下 mysql
