目前脚本运行完可能无法正常启动，那就手动初始化一下mysql

# /usr/local/mysql/bin/mysql_install_db --user=mysql --datadir=/mydata
WARNING: The host '158LDAP' could not be looked up with resolveip.
This probably means that your libc libraries are not 100 % compatible
with this binary MySQL version. The MySQL daemon, mysqld, should work
normally with the exception that host name resolving will not work.
This means that you should use IP addresses instead of hostnames
when specifying MySQL privileges !
Installing MySQL system tables...
OK
Filling help tables...
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:

/usr/local/mysql/bin/mysqladmin -u root password 'new-password'
/usr/local/mysql/bin/mysqladmin -u root -h 158LDAP password 'new-password'

Alternatively you can run:
/usr/local/mysql/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 /usr/local/mysql ; /usr/local/mysql/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /usr/local/mysql/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/local/mysql/scripts/mysqlbug script!

The latest information about MySQL is available at http://www.mysql.com/Support MySQL by buying support/licenses from http://shop.mysql.com/

出现以上提示即初始化成功

# service mysqld start
Starting MySQL.                                            [  OK  ]

最后为了方便mysql命令的调用，可以将mysql/bin的路径加入到环境变量中

在/etc/profile文件的 unset  i 上一行加入如下内容

pathmunge /usr/local/mysql/bin

并运行下面的命令即可

# source  /etc/profile
