前言
对于一个网站来说,访问日志,即access_log,对网站来说是一项很重要的功能。利用它,我们可以统计出很多有用的信息,从而给网站的运维带来方便,所以基本上每个网站都会开启这件功能。
JBoss As 7配置
在默认的情况下,JBoss7.1是没有开启access_log的,如果要开启这项功能,就需要修改$JBOSS_HOME\standalone\configuration\standalone.xml(domain.xml)这个文件,相关的修改内容如下所示:
当完成上面的配置并重启服务器后,你就可以访问一下你的网站,然后你就会在$JBOSS_HOME\standalone\log\default-host目录下看到一个名为access_log.2012-02-24的文件,它就是你所需要的访问日志了。
WildFly 8 配置
WildFly开启access_log的方法和JBoss 7 类似,也是找到相对应的web容器添加上配置就可以了,只不过二者使用的容器不相同,而且WildFly中必须指定log的存放目录。
如上,添加红色标记一行,即可开启WildFly 8的access_log功能,重启服务器,访问ip:8080即可在JBOSS_HOME/standalone/log目录下生成access.log。
其中
prefix指定log文件的前缀名即文件名
pattern指定日志的格式
pattern可以设置成两种方式,第一种是pattern="common",第二种是pattern="combined"
以下是笔者测试的两种格式的日志输出,访问localhost:8080
common格式的日志输出如下:
combined格式的日志输出如下:
可以看出,第二种格式的日志输出相对具体,而实际开发过程中开启哪种格式的access_log要根据需求来确定就可以了。
结束语
开启access_log的配置到此结束,若有问题,请参考以下资料,谢谢!

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
