查找 mysql的data文件安装在哪里:
进入 mysql 然后模糊搜索:
mysql> show variables like '%data%'; // 模糊搜索
mysql> show variables like 'datadir'; // 精确查找
.bash_history .mysql_history 一般是在 home 目录下的。
$HOME意思home目录般/home/xxx/xxx登陆用户名。
而如果你是root 用户登录的话,就直接在 /root 目录里面,因为root 的home 就是 root
删除文件,同时在进行登陆或备份数据库等与密码相关操作时,应该使用-p参数加入提示输入密码后,隐式输入密码。
# rm .bash_history .mysql_history //删除历史记录
# ln -s /dev/null .bash_history //将shell记录文件置空
# ln -s /dev/null .mysql_history //将mysql记录文件置空
找到mysql 的历史记录文件 例如 .mysql_history 这个文件
可以直接 rm .mysql_history 删除mysql 的历史记录
