Linux freeradius server
远程认证拨号用户服务（Remote Authentication Dial In User Service, RADIUS）是在网络访问服务器（Network Access Server, NAS）和集中存放认证信息的Radius服务器之间传输认证，授权和配置的协议，其client端多为通过拨号方式实现的NAS，主要用来将用户信息传递给服务器，RADIUS服务器则对用户进行认证，返回配置信息，在两端之间通信包括接入认证和计费请求

[root@Alicia ~]# service mysqld restart
Stopping mysqld: [ OK ]
Initializing MySQL database: 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 Alicia 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 &
You can test the MySQL daemon with mysql-test-run.pl
cd mysql-test ; perl mysql-test-run.pl
Please report any problems with the /usr/bin/mysqlbug script!
