Initializing MysqL database: WARNING: The host 'kiven-centos' could not be looked up with resolveip.
This probably means that your libc libraries are not 100 % compatible
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/bin/MysqLadmin -u root password 'new-password'
/usr/bin/MysqLadmin -u root -h kiven-centos password 'new-password'
------
Alternatively you can run:
/usr/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 ; /usr/bin/MysqLd_safe &
------
-------
Please report any problems with the /usr/bin/MysqLbug script!

这可能意味着您的libc库并不是100%兼容的
通常情况下，主机名解析不会起作用。
这意味着你应该使用IP地址而不是主机名
在指定MysqL特权时！
安装MysqL系统表……
------
要在启动时启动MysqLd，必须复制
-------
为此，启动服务器，然后发出以下命令:
/usr/bin/MysqLadmin -u root password 'new-password'
/usr/bin/MysqLadmin -u root -h kiven-centos password 'new-password'
或者您可以运行:
/usr/bin/MysqL_secure_installation
这也可以让你选择取消测试
强烈推荐生产服务器。
---------
更多的说明请参阅手册。
您可以启动MysqL守护进程:
cd /usr ; /usr/bin/MysqLd_safe &
-----------
请报告/usr/bin/MysqLbug脚本的任何问题！
这段话的重点：
1、在安装MysqL后，会创建一个 msyqld进程
2、设置root密码 ：MysqLadmin -u root password 'new-password'
重启MysqL服务器
# service MysqLd restart
Stopping MysqLd: [ OK ]
Starting MysqLd:
