[root@iZ94ax97oadZ data]# /etc/init.d/mysql start
Starting MySQL...The server quit without updating PID file (/db/mysql/data/iZ94ax97oadZ.pid).                                                      [FAILED]
[root@iZ94ax97oadZ data]# /etc/init.d/mysql stop
MySQL server PID file could not be found!                  [FAILED]

没有初始化权限表

3、解决办法

#cd /usr/local/mysql（进入mysql安装目录）
#chown -R mysql.mysql .
#su - mysql
$cd server
$scripts/mysql_install_db

4、解决问题详细步骤:

[root@iZ94ax97oadZ /]# cd /usr/local/mysql
[root@iZ94ax97oadZ mysql]# chown -R mysql.mysql .
[root@iZ94ax97oadZ mysql]# su - mysql
[mysql@iZ94ax97oadZ ~]$ cd /usr/local/mysql

OK
To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system
PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
  ./bin/mysqladmin -u root password 'new-password'
  ./bin/mysqladmin -u root -h iZ94ax97oadZ password 'new-password'
Alternatively you can run:
  ./bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.
See the manual for more instructions.
You can start the MySQL daemon with:
  cd . ; ./bin/mysqld_safe &
You can test the MySQL daemon with mysql-test-run.pl
  cd mysql-test ; perl mysql-test-run.pl

WARNING: Found existing config file ./my.cnf on the system.
Because this file might be in use, it was not replaced,
but was used in bootstrap (unless you used --defaults-file)
and when you later start the server.
The new default config file was created as ./my-new.cnf,
please compare it with your file and take the changes you need.
WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server
