# 解决方式1
# 重启

# mysql -uroot -p
Enter password:
ERROR 2002 (HY000): Cant connect to local MySQL server through socket ‘/tmp/mysql.sock’ (2)
# 解决方式1
#将配置文件/etc/my.cnf 做如下变更:
socket=/var/lib/mysql/mysql.sock –> socket=/tmp/mysql.sock
#未解决问题
# 解决方式2
在解决方式1的基础上:
停止mysql: kill -9
运行mysqld_safe –skip-grant-tables &
如果此时不想被远程连接:mysqld_safe –skip-grant-tables –skip-networking &
使用mysql连接server:mysql -uroot -p
更改密码: update mysql.user set authentication_string=password(‘123qwe’) where user=’root’ and Host = ‘localhost’;
*特别提醒注意的一点是,新版的mysql数据库下的user表中已经没有Password字段了
而是将加密后的用户密码存储于authentication_string字段
mysql> flush privileges;
mysql> quit;
修改完毕。重启
killall -TERM mysqld。
mysqld_safe &
#解决问题
