注意:Tomcat有两种安装方式,一种是直接解压就可以使用的二进制文件,第二种是编译安装,我们这里采用了第一种方法,下载的tomcat软件直接解压就可以执行的二进制文件,因为在官方默认下载的便是使用第一种方法安装,那么下载解压后的目录如下:
tomcat
|---bin Tomcat:存放启动和关闭tomcat脚本;
|---conf Tomcat:存放不同的配置文件(server.xml和web.xml);
|---lib:包含Tomcat使用的jar文件.unix平台此目录下的任何文件都被加到Tomcat的classpath中;
|---logs:存放Tomcat执行时的LOG文件;
|---webapps:Tomcat的主要Web发布目录(包括应用程序示例);
|--- ROOT:tomcat的家目录
|--- index.jsp:Tomcat的默认首页文件
|---work:存放jsp编译后产生的class文件或servlet文件存放
|---temp:存放Tomcat运行时所产生的临时文件

#######################################################################
JAVA_OPTS=‘-server -Xms64m -Xmx128m‘是用来设置JAVA相关运行参数的变量
-server 一定要作为第一个参数,在多个CPU时性能佳
-Xms 初始heap(堆)大小,使用最小内存大小,cpu性能高时此值应该设大一些
-Xmx Java heap最大值,使用内存的最大值
上面两个值分配的是JVM的最小和最大值,取决于硬件的物理内存大小,建议为物理内存的一般,不超过80%
JAVA_HOME=/usr/local/jdk1.8.0_60 指定Tomcat目录
$CATALINA_HOME=/usr/local/tomcat $* 指定运行tomcat的脚本
//赋予权限
[root@duwers21 ~]# chmod +x/etc/init.d/tomcat
//启动

点击manager App,需要一个用户名和密码:
[root@duwers21 ~]# cp/server/tomcat/conf/tomcat-users.xml /server/tomcat/conf/tomcat-users.xml.back
然后修改tomcat-users.xml,在最后面改成下面的样子:【红色为自定义】
<role rolename="tomcat"/>
<role rolename="role1"/>
<role rolename="manager-gui"/>
<userusername="redhat" password="123456"roles="manager-gui"/>
<user username="tomcat" password="tomcat"roles="tomcat"/>
<user username="both" password="tomcat"roles="tomcat,role1"/>
<user username="role1" password="tomcat"roles="role1"/>
################################################################################
几种角色
1:“manager-gui”:Allowsaccess to the html interface(允许通过web的方式登录查看服务器信息)。
2:“manager-script”: Allowsaccess to the plain text interface(允许以纯文本的方式访问)。
3:“manager-jmx”: Allowsaccess to the JMX proxy interface(允许jmx的代理访问)。
4:“manager-status”: Allowsaccess to the read-only status pages(允许以只读状态访问)。

server.xml是Tomcat的主配置文件(全局),服务器设置的,例如端口设置,路径设置。
context里设置tomcat数据源,用来连接数据库。
tomcat_user主要是用户名和密码的设置。
web是默认首页等等之类的设置
[root@duwers21 ~]# vim/server/tomcat/conf/server.xml [root@duwers21 ~]# tail -10/server/tomcat/conf/server.xml <Hostname="duwers21.com" appBase="/var/www/html"> <Context path=""docBase="/var/www/html/web1"/> </Host> <Host name="duwers21.space"appBase="/var/www/html"> <Context path=""docBase="/var/www/html/web2"/> </Host> </Engine> </Service> </Server> [root@duwers21 ~]#
####################################################################################################
appBase指定应用程序(网站)的基本路径,这里可以存放多个程序(网站),一般是相对路径,相对于tomcat的安装目录。
Context path=""为虚拟目录,如果是空,表示直接就是/,如果是如path="aa",那么访问的时候就是site:8080/aa
docBase="……" 为实际目录,就是可以是绝对路径,如果是相对路径就是基于appBase
[root@duwers21 ~]# mkdir -p/var/www/html/{web1,web2} [root@duwers21 ~]# echo duwers21.com >/var/www/html/web1/index.html [root@duwers21 ~]# echo duwers21.space >/var/www/html/web2/index.html [root@duwers21 ~]# service tomcat stop ;service tomcat start Using CATALINA_BASE: /server/tomcat Using CATALINA_HOME: /server/tomcat Using CATALINA_TMPDIR: /server/tomcat/temp Using JRE_HOME: /usr Using CLASSPATH: /server/tomcat/bin/bootstrap.jar:/server/tomcat/bin/tomcat-juli.jar Using CATALINA_BASE: /server/tomcat Using CATALINA_HOME: /server/tomcat Using CATALINA_TMPDIR: /server/tomcat/temp Using JRE_HOME: /usr Using CLASSPATH: /server/tomcat/bin/bootstrap.jar:/server/tomcat/bin/tomcat-juli.jar Tomcat started.

omcat 可以使用 apr 来提供更好的伸缩性、性能和集成到本地服务器技术。用来提高 tomcat 的性能。 tomcat native 在具体的运行平台上,提供了一种优化技术,它本身是基于 ARP(Apache Portable(轻便) Runtime)技术
我们应用了 tomcat native 技术之后,tomcat 在跟操作系统级别的交互方面可以做得更好,并且它更像apache 一样,可以更好地作为一台 web server。 tomcat 可以利用 apache 的 apr 接口,使用操作系统的部分本地操作,从而提升性能APR 提升的是静态页面处理能力
关于tomcat-native的相关介绍及下载: http://tomcat.apache.org/download-native.cgi
