解决方法:
在MySQL中,需要使用socket方式连接localhost;而当使用-h选项登陆数据库时,后面接的应该是IP地址或主机名。

查询socket

[root@localhost Percona-Server-5.6.34-rel79.1-Linux.x86_64.ssl101]# ps -ef|grep mysql

root      2940  2917  0 15:31 pts/0    00:00:00 /bin/sh bin/mysqld_safe --defaults-file=/u01/mysql_data/my.cnf
mysql     3837  2940  0 15:31 pts/0    00:00:07 /mysql5.6/Percona-Server-5.6.34-rel79.1-Linux.x86_64.ssl101/bin/mysqld --defaults-file=/u01/mysql_data/my.cnf --basedir=/database/percona --datadir=/u01/mysql_data --plugin-dir=/database/percona/lib/mysql/plugin --user=mysql --log-error=/u01/mysql_data/mysqld_error.log --open-files-limit=8192 --pid-file=/u01/mysql_data/localhost.localdomain.pid --socket=/u01/mysql_data/mysql.sock --port=3306
root      5346  2917  0 17:05 pts/0    00:00:00 grep mysql

使用-S连接socket的方式登录数据库

[root@localhost Percona-Server-5.6.34-rel79.1-Linux.x86_64.ssl101]# bin/mysql -S /u01/mysql_data/mysql.sock -uroot -p
Enter password:

使用-h接主机名的方式连接到数据库
[root@localhost Percona-Server-5.6.34-rel79.1-Linux.x86_64.ssl101]# bin/mysql -h localhost.localdomain -P 3306 -uroot -p
