使用rpm -ql mysql-community-server發現並無安裝過mysqld_safe這個文件，解決方法是換一種重置密碼的方式：在my.cnf文件的[mysqld]下面添加skip-grant-tables選項，重啓mysqld服務便可本機無密碼登陸。mysql

[root@localhost ~]# mysql -u root

my.cnf的路徑通常是/etc/my.cnf，不過也有人說是在/usr/my.cnfsql

[mysqld]
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.

datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
skip-grant-tables   # 添加這一行
