My problem started off with me not being able to log in as root any more on my mysql install.
(我的问题开始于我无法以root用户身份登录mysql安装。)
I was attempting to run mysql without passwords turned on... but whenever I ran the command (我试图在不打开密码的情况下运行mysql ...但是每当我运行命令时)
# mysqld_safe --skip-grant-tables &
I would never get the prompt back.
(我永远也回不了提示。)
I was trying to follow these instructions to recover the password . (我试图按照以下说明恢复密码 。)
The screen just looks like this:
(屏幕如下所示：)
root@jj-SFF-PC:/usr/bin# mysqld_safe --skip-grant-tables
120816 11:40:53 mysqld_safe Logging to syslog.
120816 11:40:53 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
and I don't get a prompt to start typing the SQL commands to reset the password.
(并且没有提示您开始输入SQL命令来重置密码。)
When I kill it by pressing CTRL + C , I get the following message:
(当我按CTRL + C杀死它时，我收到以下消息：)
error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)'
Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!
If I retry the command and leave it long enough, I do get the following series of messages:
(如果重试该命令并将其保留足够长的时间，则会收到以下一系列消息：)
root@jj-SFF-PC:/run/mysqld# 120816 13:15:02 mysqld_safe Logging to syslog.
120816 13:15:02 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql
120816 13:16:42 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended
[1]+ Done mysqld_safe --skip-grant-tables
root@jj-SFF-PC:/run/mysqld#
But then if I try to log in as root by doing:
(但是，如果我尝试通过以下方式以root用户身份登录：)
# mysql -u root
I get the following error message:
(我收到以下错误消息：)
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
I checked and /var/run/mysqld/mysqld.sock file doesn't not exist.
(我检查了/var/run/mysqld/mysqld.sock文件不存在。)
The folder does, but not the file. (文件夹可以，但文件不能。)
Also, I dunno if this helps or not, but I ran find / -name mysqld and it came up with:
(另外，我不知道这是否有帮助，但是我find / -name mysqld ，结果是：)
/var/run/mysqld - folder
/usr/sbin/mysqld - file
/run/mysqld - folder
I'm new to Linux and MySQL, so I don't know if this is normal or not.
(我是Linux和MySQL的新手，所以我不知道这是否正常。)
But I'm including this info just in case it helps. (但我会包含此信息，以防万一。)
I finally decided to uninstall and reinstall mysql.
(我终于决定卸载并重新安装mysql。)
apt-get remove mysql-server
apt-get remove mysql-client
apt-get remove mysql-common
apt-get remove phpmyadmin
After reinstalling all packages again in the same order as above, during the phpmyadmin install, I got the same error:
(按照上述相同的顺序重新安装所有软件包后，在phpmyadmin安装过程中，出现了相同的错误：)
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
So I tried again to uninstall/reinstall.
(所以我再次尝试卸载/重新安装。)
This time, after I uninstalled the packages, I also manually renamed all mysql files and directories to mysql.bad in their respective locations. (这次，在卸载软件包之后，我还手动将所有mysql文件和目录在各自的位置重命名为mysql.bad 。)
/var/lib/mysql
/var/lib/mysql/mysql
/var/log/mysql
/usr/lib/perl5/DBD/mysql
/usr/lib/perl5/auto/DBD/mysql
/usr/lib/mysql
/usr/bin/mysql
/usr/share/mysql
/usr/share/dbconfig-common/internal/mysql
/etc/init.d/mysql
/etc/apparmor.d/abstractions/mysql
/etc/mysql
Then I tried to reinstall mysql-server and mysql-client again.
(然后，我尝试再次重新安装mysql-server和mysql-client 。)
But I've noticed that it doesn't prompt me for a password. (但是我注意到它不会提示我输入密码。)
Isn't it supposed to ask for an admin password? (它不是应该要求管理员密码吗？)
