Percona Server is distributed with several useful UDF (User Defined Function) from Percona Toolkit.
Run the following commands to create these functions:
mysql -e "CREATE FUNCTION fnv1a_64 RETURNS INTEGER SONAME 'libfnv1a_udf.so'"
mysql -e "CREATE FUNCTION fnv_64 RETURNS INTEGER SONAME 'libfnv_udf.so'"
mysql -e "CREATE FUNCTION murmur_hash RETURNS INTEGER SONAME 'libmurmur_udf.so'"
See http://www.percona.com/doc/percona-server/5.7/management/udf_percona_toolkit.html for more details

启动MySQL

service mysql start
#centos 7
systemctl start mysql.service
grep password /var/log/mysqld.log

安装完成后，会生成一个随机的root密码：

[root@bogon ~]# grep password /var/log/mysqld.log
