如何在MySQL中重置我的root密碼？

Question

我在連接到MySQL從Ubuntu的16.04麻煩：

mysql -u root -p 

返回錯誤：

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) 

當我試圖啓動與服務器：

sudo service mysql start 
mysqld_safe --skip-grant-tables & 

的輸出是：

# 2017-01-26T20:11:45.329764Z mysqld_safe Logging to syslog. 
2017-01-26T20:11:45.333031Z mysqld_safe Logging to '/var/log/mysql/error.log'. 
2017-01-26T20:11:45.336684Z mysqld_safe Logging to '/var/log/mysql/error.log'. 
2017-01-26T20:11:45.358956Z mysqld_safe A mysqld process already exists 

如果我殺死的過程：

ps aux | grep "msyql" 
kill -9 pid 

，然後運行：

mysqld_safe --skip-grant-tables & 

我得到：

2017-01-26T20:10:07.979813Z mysqld_safe Logging to '/var/log/mysql/error.log'. 
2017-01-26T20:10:07.984114Z mysqld_safe Logging to '/var/log/mysql/error.log'. 
2017-01-26T20:10:07.987546Z mysqld_safe Directory '/var/run/mysqld' for UNIX socket file don't exists. 

這是一個死循環。那麼如果我從頭開始重新安裝呢？

首先拆下的MySQL：

sudo apt-get remove --purge mysql-server mysql-client mysql-common 
sudo apt-get autoremove 
sudo apt-get autoclean 

然後重新安裝：

sudo apt-get update 
sudo apt-get install mysql-server 
sudo mysql_install_db // (deprecated command) 
sudo /usr/bin/mysql_secure_installation 

就在這裏：

sudo /usr/bin/mysql_secure_installation 

Securing the MySQL server deployment. 

Enter password for user root: 
Error: Access denied for user 'root'@'localhost' (using password: YES) 

或：

mysqladmin -u root password [newpass] 
mysqladmin: connect to server at 'localhost' failed 
error: 'Access denied for user 'root'@'localhost' (using password: NO)' 

然後它倒下。

我已試過這裏所有的答案 - ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

有時一個臨時密碼是根據他人存儲，但建議

任何人這不是存儲在/var/log/mysqld.log能夠幫助嗎？
