Starting MySQL.The server quit without updating PID file (datamysqllinux.pid).

问题现象：
启动mysql的时候报如下错误：

Starting MySQL.The server quit without updating PID file (datamysqllinux.pid).

分析过程：

查看启动日志：

InnoDB: 127 rollback segment(s) active.

InnoDB: Creating foreign key constraint system tables

InnoDB: Foreign key constraint system tables created

130827 10:46:47  InnoDB: Waiting for the background threads to start

130827 10:46:48 InnoDB: 5.5.32 started; log sequence number 0

130827 10:46:48 [Note] Server hostname (bind-address): '0.0.0.0'; port: 3306

130827 10:46:48 [Note]   - '0.0.0.0' resolves to '0.0.0.0';

130827 10:46:48 mysqld_safe mysqld from pid file /data/mysql/linux.pid ended

从日志可以看出系统表没有创建，但mysql_install_db这个脚本是运行过的；

运行时的界面如下：

linux:/usr/bin # perl  mysql_install_db

Installing all prepared tables

130827 10:51:13  /usr/sbin/mysqld: Shutdown Complete

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'

/usr/bin/mysqladmin -u root -h linux.site password 'new-password'

See the manual for more instructions.

NOTE:  If you are upgrading from a MySQL <= 3.22.10 you should run

the /usr/bin/mysql_fix_privilege_tables. Otherwise you will not be

able to use the new GRANT command!

You can test the MySQL daemon with the benchmarks in the 'sql-bench' directory:

cd sql-bench ; perl run-all-tests

Please report any problems with the /usr/bin/mysqlbug script!

但是执行过mysql_install_db后，数据目录下仍旧为空；系统表未创建成功；

问题原因和解决方法：
 mysql_install_db没加特定参数，系统表没有创建成功；

重新加参数执行mysql_install_db之后可以成功创建系统表，mysql启动成功；

mysql_install_db  --basedir=/usr/local/mysql
--datadir=/data/mysql/
