简介

Tomcat是Apache 软件基金会（Apache Software Foundation）的Jakarta 项目中的一个核心项目，由Apache、Sun 和其他一些公司及个人共同开发而成。由于有了Sun 的参与和支持，最新的Servlet 和JSP 规范总是能在Tomcat 中得到体现，Tomcat 5支持最新的Servlet 2.4 和JSP 2.0 规范。因为Tomcat 技术先进、性能稳定，而且免费，因而深受Java 爱好者的喜爱并得到了部分软件开发商的认可，成为目前比较流行的Web 应用服务器。

Tomcat 服务器是一个免费的开放源代码的Web 应用服务器，属于轻量级应用服务器，在中小型系统和并发访问用户不是很多的场合下被普遍使用，是开发和调试JSP 程序的首选。对于一个初学者来说，可以这样认为，当在一台机器上配置好Apache 服务器，可利用它响应HTML（标准通用标记语言下的一个应用）页面的访问请求。实际上Tomcat是Apache 服务器的扩展，但运行时它是独立运行的，所以当你运行tomcat 时，它实际上作为一个与Apache 独立的进程单独运行的。

诀窍是，当配置正确时，Apache 为HTML页面服务，而Tomcat 实际上运行JSP 页面和Servlet。另外，Tomcat和IIS等Web服务器一样，具有处理HTML页面的功能，另外它还是一个Servlet和JSP容器，独立的Servlet容器是Tomcat的默认模式。不过，Tomcat处理静态HTML的能力不如Apache服务器。目前Tomcat最新版本为9.0。

类似于Apache，Nginx等web服务器

nginx和httpd只能处理html等静态文件（jpg），配合PHP就能够处理动态的网页（以.php结尾）、

但Tomcat处理静态HTML的能力不如Nginx、Apache

软件版本选择

JDK下载：http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html、

Tomcat下载：http://tomcat.apache.org/

说明：在生产环境下，使用Tomcat安装版本需要同开发协商，Tomcat和JDK版本必须并行（tomcat8<=>jdk8）

Tomcat安装

安装JDK（以后所有涉及到java应用的都需要安装）

JDK->JAVA虚拟机（jvm）>一处编译，处处使用

[root@cairui software]# tar xf jdk-8u161-linux-x64.tar.gz
[root@cairui software]# ls

[root@cairui software]# ls

drwxr-xr-x 9 root root 4096 Mar 23 12:40 tomcat-8.0.50
[root@cairui opt]# echo 'export TOMCAT_HOME=/opt/tomcat'>>/etc/profile
[root@cairui opt]# source /etc/profile
[root@cairui opt]# useradd tomcat -s /sbin/nologin -M
[root@cairui opt]# chown -R tomcat.tomcat /opt/jdk /opt/tomcat
[root@cairui opt]# ll
total 8
lrwxrwxrwx 1 tomcat tomcat    7 Mar 23 12:14 jdk -> jdk1.8/
drwxr-xr-x 8 uucp      143 4096 Dec 20 08:24 jdk1.8
lrwxrwxrwx 1 tomcat tomcat   14 Mar 23 12:41 tomcat -> tomcat-8.0.50/
drwxr-xr-x 9 root   root   4096 Mar 23 12:40 tomcat-8.0.50

方法二：即用开发工具将程序打包成war包。然后上传到webapps下

搭建Jpress->java版本的wordpress

安装配置数据库

[root@cairui opt]# rpm -qa | grep mysql*
[root@cairui opt]# yum install mysql -y    
[root@cairui opt]# yum install mysql-server -y
[root@cairui opt]# yum install mysql-devel -y
[root@cairui opt]# /etc/init.d/mysqld start
Initializing MySQL database:  Installing MySQL system tables...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h cairui password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/bin/mysqlbug script!

                                                           [  OK  ]
Starting mysqld:                                           [  OK  ]
[root@cairui opt]# /usr/bin/mysqladmin -u root password '123456'
[root@cairui opt]# source /etc/profile
[root@cairui opt]# mysql -uroot -p123456
