JAVA/JSP学习系列之四(Orion App Server的安装)_MySQL
一、前言
Orion这个东西,小巧,但是功能却非常多,废话不讲,看它目前的支持就知道了:
(1)Servlets/JSP
(2)EJB
(3)HTTP (注:说明不再需要Apache或者IIS等Web Server)
二、下载,安装
下载地址为Orion Application Server官方站点:http://www.orionserver.com/,我下载的是Orion1.4版本。
下载完,解压到一个目录,我这里用E:\Orion作为例子。
三、配置
(1)根据Orion官方站点的安装说明,如果要支持JSP等技术的话,要将JDK的tools.jar复制到e:\orion目录下,tools.jar文件在你安装的JDK目录的lib子目录下。
到现在,其实已经成功了缺省的配置了,如果你的80端口没有被占用,而且你也想用80作为端口的话,你到这里已经完成了,否则,请继续下面的配置。
(2)配置端口
在E:\orion\config目录下有个default-web-site.xml文件,找到文件中下面行:
将这行改为:
注意,我这里使用的是8008端口。
四、测试
(1)启动Orion:
在Orion目录下,command方式运行:
java -jar orion.jar
将出现Orion/x.x.x initialized,我这里版本是1.4所以显示:
Orion/1.4.0 initialized
到此,说明你已经成功了。
(2)执行jsp文件
在浏览器中输入:
http://localhost:8008/
出现:Orion Application Server 1.4.0 - Up and running,下面有JSP examples你可以试着运行。

MySQL processes data replication through three modes: asynchronous, semi-synchronous and group replication. 1) Asynchronous replication performance is high but data may be lost. 2) Semi-synchronous replication improves data security but increases latency. 3) Group replication supports multi-master replication and failover, suitable for high availability requirements.

The EXPLAIN statement can be used to analyze and improve SQL query performance. 1. Execute the EXPLAIN statement to view the query plan. 2. Analyze the output results, pay attention to access type, index usage and JOIN order. 3. Create or adjust indexes based on the analysis results, optimize JOIN operations, and avoid full table scanning to improve query efficiency.

Using mysqldump for logical backup and MySQLEnterpriseBackup for hot backup are effective ways to back up MySQL databases. 1. Use mysqldump to back up the database: mysqldump-uroot-pmydatabase>mydatabase_backup.sql. 2. Use MySQLEnterpriseBackup for hot backup: mysqlbackup--user=root-password=password--backup-dir=/path/to/backupbackup. When recovering, use the corresponding life

The main reasons for slow MySQL query include missing or improper use of indexes, query complexity, excessive data volume and insufficient hardware resources. Optimization suggestions include: 1. Create appropriate indexes; 2. Optimize query statements; 3. Use table partitioning technology; 4. Appropriately upgrade hardware.

MySQL view is a virtual table based on SQL query results and does not store data. 1) Views simplify complex queries, 2) Enhance data security, and 3) Maintain data consistency. Views are stored queries in databases that can be used like tables, but data is generated dynamically.

MySQL partitioning improves performance and simplifies maintenance. 1) Divide large tables into small pieces by specific criteria (such as date ranges), 2) physically divide data into independent files, 3) MySQL can focus on related partitions when querying, 4) Query optimizer can skip unrelated partitions, 5) Choosing the right partition strategy and maintaining it regularly is key.

How to grant and revoke permissions in MySQL? 1. Use the GRANT statement to grant permissions, such as GRANTALLPRIVILEGESONdatabase_name.TO'username'@'host'; 2. Use the REVOKE statement to revoke permissions, such as REVOKEALLPRIVILEGESONdatabase_name.FROM'username'@'host' to ensure timely communication of permission changes.
