Ubuntu

今天搭建了一个ubuntu 64位的tomcat + java + mysql的环境，现在总结一下：

1.下载jdk

地址:

http://download.oracle.com/otn-pub/java/jdk/7u51-b13/jdk-7u51-linux-x64.tar.gz?AuthParam=1394967394_1531ce17d13be0962e25ec8fe3e45f1d

安装:

tar xvf 解压刚下载的jdk压缩包。

然后到/etc/profile（注释：使用vi命令）文件中，配置环境变量（注释:假设jdk解压后目录为/softsetupdir/jdk1.7.0_51)

将下面三行内容放到profile文件的尾部，并保存

export JAVA_HOME=/softsetupdir/jdk1.7.0_51

export PATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/bin

export CLASSPATH=$JAVA_HONE/lib;$JAVA_HONE/jre/lib:.

要这些配置马上生效，需要执行:

source /etc/profile

测试：

此时，你在命令行中输入java,javac命令应该就可以了，也说明你的jdk已经配置好了

2.下载tomcat

地址:

http://mirrors.cnnic.cn/apache/tomcat/tomcat-8/v8.0.3/bin/apache-tomcat-8.0.3.tar.gz

安装:

放心，tomcat下载下来后，解压缩就可以了，然后在解压的bin目录中执行脚本startup.sh就启动tomcat服务了

测试:

http://ip地址:8080

看浏览器能否出现tomcat的docs文档，如果能，则说明tomcat好了。

3.按照mysql

sudo apt-get install mysql-server

安装完毕后，mysql环境变量自己也即配置完了。

测试:

输入:

mysql -p

输入密码

如果能连接上mysql，则说明mysql好了

扩展：mysql服务的启动与停止

service mysql stop

service mysql start

service mysql restart

4.配置域名

在域名中心将域名帮定到该机器的Ip地址

例子：只需要修改xxx.xxx.xxx.xxx为自己的ip地址就行了，随便给我自己的域名打个广告

主机名 (A)(最多允许20条) IP 地址 TTL 操作帮助

www.uhdesk.com

xxx.xxx.xxx.xxx 3600 修改 - 删除

5.此时发现需要输入域名的同时，还要加上端口才能访问该机tomcat的webapps/root下的index.htm

为了解决这个问题，需要将tomcat提供Http的服务端口改为80.

原因：浏览器发出http请求的时候，默认端口是80.

What are stored procedures in MySQL?May 01, 2025 am 12:27 AM

Stored procedures are precompiled SQL statements in MySQL for improving performance and simplifying complex operations. 1. Improve performance: After the first compilation, subsequent calls do not need to be recompiled. 2. Improve security: Restrict data table access through permission control. 3. Simplify complex operations: combine multiple SQL statements to simplify application layer logic.

How does query caching work in MySQL?May 01, 2025 am 12:26 AM

The working principle of MySQL query cache is to store the results of SELECT query, and when the same query is executed again, the cached results are directly returned. 1) Query cache improves database reading performance and finds cached results through hash values. 2) Simple configuration, set query_cache_type and query_cache_size in MySQL configuration file. 3) Use the SQL_NO_CACHE keyword to disable the cache of specific queries. 4) In high-frequency update environments, query cache may cause performance bottlenecks and needs to be optimized for use through monitoring and adjustment of parameters.

What are the advantages of using MySQL over other relational databases?May 01, 2025 am 12:18 AM

The reasons why MySQL is widely used in various projects include: 1. High performance and scalability, supporting multiple storage engines; 2. Easy to use and maintain, simple configuration and rich tools; 3. Rich ecosystem, attracting a large number of community and third-party tool support; 4. Cross-platform support, suitable for multiple operating systems.

How do you handle database upgrades in MySQL?Apr 30, 2025 am 12:28 AM

The steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.

What are the different backup strategies you can use for MySQL?Apr 30, 2025 am 12:28 AM

MySQL backup policies include logical backup, physical backup, incremental backup, replication-based backup, and cloud backup. 1. Logical backup uses mysqldump to export database structure and data, which is suitable for small databases and version migrations. 2. Physical backups are fast and comprehensive by copying data files, but require database consistency. 3. Incremental backup uses binary logging to record changes, which is suitable for large databases. 4. Replication-based backup reduces the impact on the production system by backing up from the server. 5. Cloud backups such as AmazonRDS provide automation solutions, but costs and control need to be considered. When selecting a policy, database size, downtime tolerance, recovery time, and recovery point goals should be considered.

How do you optimize database schema design for performance in MySQL?Apr 30, 2025 am 12:27 AM

Optimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance efficiency.
