FreeRadius
本文献给广大linux的爱好者
有人居然说设置radius要卖钱,本人花了几天的功夫,看了些资料,终于成功设置radius服务器,现在贴出来和大家分享。
笔者用的平台是RedHat Linux 7.2
一、安装mysql
本人用的是光盘上的RPM包
rpm –ivh mysql-3.23.41.1.i386.rpm
rpm –ivh mysql-devel-3.23.41.1.i386.rpm
rpm –ivh mysql-server-3.23.41.1.i386.rpm
rpm –ivh mysqlclient9-3.23.22-6.i386.rpm
启动mysql服务
service mysqld start
更改mysql的root密码(注意:mysql的root 和系统的root是2个不用的概念)
mysql –uroot –p
创建radius数据库
creat database radius;
use mysql;
update user set password=password(‘你的密码’) where user=’root’;
允许远程机器连接
update user set host=’%’ where user=’root’;
退出及重新启动mysql
quit
service mysqld restart
二、安装openSSL
本人也是用的光盘上的RPM包
rpm –ivh openssl095a-0.9.5a-11.i386.rpm
rpm –ivh openssl096-0.9.6-6.i386.rpm
三、安装freeradius
从www.freeradius.org上下载freeraidus,本文版本是0.8.1
编译和安装
tar xvfz freeradius.tar.gz
cd xvfz freeradius-0.8.1
./configure
make
make install
建立mysql的数据库raius的表
cd src/modules/rlm_sql/drivers/rlm_sql_mysql
mysql –uroot –p密码 radius 更改freeradius的设置
cd /usr/local/etc/raddb
更改radiusd.conf,让其支持sql (如下面所说)
authorize {
preprocess
chap
mschap
suffix
sql
}
accouting {
….
sql
…
}
更改sql.conf
server=”localhost”
login=”root”
password=”mysql的root的密码”
radius_db=”radius”
更改 client.conf支持所用的NAS具体可以看该文档,要注意的是secret是NAS和radius服务器的共享密码
数据库加入测试账号
加入组
mysql –uroot –p密码 radius
insert into radgroupreply (groupname,attribute,op,values) values (‘user’,‘Auth-Type’,’:=’,’Local’);
insert into radgroupreply (groupname,attribute,op,values) values (‘user’,‘Service-Type’,’:=’,’Framed-User’);
insert into radgroupreply (groupname,attribute,op,values) values (‘user’,‘Framed-IP-Address’,’:=’,’255.255.255.254’);
insert into radgroupreply (groupname,attribute,op,values) values (‘user’,‘Framed-IP-Netmask’,’:=’,’255.255.255.0’);
加入测试账号
insert into radcheck (username,attribute,op,value) values (‘test’,’User-Password’,’:=’,’test’)
测试账号加入组
insert into usergroup (username,groupname) values (‘test’,’user’);
四、启动radius服务、测试账号
启动到debug模式
radiusd –X
有时候会报找不到文件rlm_sql_mysql这个时候只要把库文件加入系统搜索的目录里
比如:
cp /usr/local/lib/* /usr/lib
测试账号
radtest test teset localhost 0 testing123
如果能看到radius的应答,恭喜服务器设置成功了。
本人才疏,如果本文有错误,请大家指正,并欢迎一起讨论。

In database optimization, indexing strategies should be selected according to query requirements: 1. When the query involves multiple columns and the order of conditions is fixed, use composite indexes; 2. When the query involves multiple columns but the order of conditions is not fixed, use multiple single-column indexes. Composite indexes are suitable for optimizing multi-column queries, while single-column indexes are suitable for single-column queries.

To optimize MySQL slow query, slowquerylog and performance_schema need to be used: 1. Enable slowquerylog and set thresholds to record slow query; 2. Use performance_schema to analyze query execution details, find out performance bottlenecks and optimize.

MySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.

MySQL asynchronous master-slave replication enables data synchronization through binlog, improving read performance and high availability. 1) The master server record changes to binlog; 2) The slave server reads binlog through I/O threads; 3) The server SQL thread applies binlog to synchronize data.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

The installation and basic operations of MySQL include: 1. Download and install MySQL, set the root user password; 2. Use SQL commands to create databases and tables, such as CREATEDATABASE and CREATETABLE; 3. Execute CRUD operations, use INSERT, SELECT, UPDATE, DELETE commands; 4. Create indexes and stored procedures to optimize performance and implement complex logic. With these steps, you can build and manage MySQL databases from scratch.

InnoDBBufferPool improves the performance of MySQL databases by loading data and index pages into memory. 1) The data page is loaded into the BufferPool to reduce disk I/O. 2) Dirty pages are marked and refreshed to disk regularly. 3) LRU algorithm management data page elimination. 4) The read-out mechanism loads the possible data pages in advance.

MySQL is suitable for beginners because it is simple to install, powerful and easy to manage data. 1. Simple installation and configuration, suitable for a variety of operating systems. 2. Support basic operations such as creating databases and tables, inserting, querying, updating and deleting data. 3. Provide advanced functions such as JOIN operations and subqueries. 4. Performance can be improved through indexing, query optimization and table partitioning. 5. Support backup, recovery and security measures to ensure data security and consistency.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
