Ubuntu下快速安装jdk、tomcat、mysql和Redis安装之前,先执行系统更新
apt-get update
一、安装Java
1、在线安装JDK
a、apt-get install openjdk-6-jdk
b、apt-get install openjdk-6-jre
备注:通常只需要安装jdk即可,因为jdk下面包括jre,jdk是开发工具包,jre是java运行环境
2、手动安装JDK
./jdk-6u38-linux-x64.bin
完成安装之后,将解压的jdk1.6.0_38移至/usr/lib/jvm/jdk1.6.0_38
配置环境变量:
>> vi /root/.bashrc
JAVA_HOME=/usr/lib/jvm/jdk1.6.0_38
CLASSPATH=.:$JAVA_HOME/lib
PATH=$PATH:$JAVA_HOME/bin
export JAVA_HOME
export CLASSPATH
export PATH
然后
>> source /root/.bashrc
备注:解决Java new Date()与系统时间不一致的问题
在Server上边写一段Java程序,通过Java new Date()来获取时间,用于测试是否与当前系统时间是否一致,如果不一致,就通过如果方案来解决时区不一致的问题
在命令行设置TimeZone 如下:
export TZ="Asia/Shanghai" //或者直接将此命令嵌入到配置Java的环境变量中
再运行Java new Date()程序来测试获取的时区是否与当前Server一致
二、安装tomcat
apt-get install tomcat6
备注:安装完之后,Ubuntu自动将tomcat6加入到系统Service下
?
三、安装mysql
1、apt-get install mysql-server-5.5
2、安装过程中,会跳出字符界面,提示设置root密码
3、安装完之后,可以通过service mysql status查看mysql是否正确启动
4、修改my.cnf配置文件,将bind-address = 127.0.0.1前面加“#”注释掉,这样就可以允许其他机器远程访问本机mysql了
5、修改完my.cnf配置之后,重启mysql服务(service mysql restart)
6、进入mysql数据库,mysql -u root -p然后输入安装时设置的密码进入mysql控制台
7、在mysql控制台可以添加和修改用户以及用户密码,这里我修改root密码,命令如下:
mysql> grant all privileges on *.* to root@localhost identified by "123456" //这里只允许本地可以通过root用户访问
mysql> grant all privileges on *.* to test@localhost identified by "123456" //这里新建一个test用户
mysql> grant all privileges on *.* to test@"%" identified by "123456" //这里允许通过test用户远程访问
mysql> flush privileges ;
8、在远程桌面上,test用户就可以通过mysql GUI连接工具进行远程操作
备注:解决MySQL出现大量unauthenticated user的问题,导致线程卡死,服务器不能连接mysql,在my.cnf中的【mysqld】下加入配置skip-name-resolve,然后重?
启即可
四、安装redis-server
1、apt-get install redis-server
2、安装完之后,可以通过service redis-server status查看mysql是否正确启动
3、进入到/etc/redis/redis.conf将bind-address = 127.0.0.1前面加“#”注释掉,这样就可以允许其他机器远程访问本机redis-server了

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.

InnoDB is suitable for applications that require transaction support and high concurrency, while MyISAM is suitable for applications that require more reads and less writes. 1.InnoDB supports transaction and bank-level locks, suitable for e-commerce and banking systems. 2.MyISAM provides fast read and indexing, suitable for blogging and content management systems.

There are four main JOIN types in MySQL: INNERJOIN, LEFTJOIN, RIGHTJOIN and FULLOUTERJOIN. 1.INNERJOIN returns all rows in the two tables that meet the JOIN conditions. 2.LEFTJOIN returns all rows in the left table, even if there are no matching rows in the right table. 3. RIGHTJOIN is contrary to LEFTJOIN and returns all rows in the right table. 4.FULLOUTERJOIN returns all rows in the two tables that meet or do not meet JOIN conditions.

Common security vulnerabilities in MySQL include SQL injection, weak passwords, improper permission configuration, and unupdated software. 1. SQL injection can be prevented by using preprocessing statements. 2. Weak passwords can be avoided by forcibly using strong password strategies. 3. Improper permission configuration can be resolved through regular review and adjustment of user permissions. 4. Unupdated software can be patched by regularly checking and updating the MySQL version.

Identifying slow queries in MySQL can be achieved by enabling slow query logs and setting thresholds. 1. Enable slow query logs and set thresholds. 2. View and analyze slow query log files, and use tools such as mysqldumpslow or pt-query-digest for in-depth analysis. 3. Optimizing slow queries can be achieved through index optimization, query rewriting and avoiding the use of SELECT*.

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),

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.
