本来初始化配置是这样的：
scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql
出现了
[root@localhost mysql-5.6.14]# service mysql restart
error! mysql server pid file could not be found!
starting mysql. error! the server quit without updating pid file (/var/lib/mysql/localhost.localdomain.pid).
在日志中出现了如下错误：
can't open and lock privilege tables: table 'mysql.user' doesn't exist
后来采用了下面的语句就可以了：
scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql --ldata=/var/lib/mysql
