Tomcat部署步骤

2.1、下载并安装JDK

1、JDK是Java语言的软件开发工具包

2、JDK是Tomcat运行的必要环境 3、根据计算机硬件配置，选择安装包

[root@server1 opt]# tar zxf jdk-8u91-linux-x64.tar.gz[root@server1 opt]# mv jdk1.8.0_91/ /usr/local/java[root@server1 opt]# cd /etc/profile.d/[root@server1 profile.d]# vim java.shexport JAVA_HOME=/usr/local/java ###设置java根目录export PATH=$PATH:$JAVA_HOME/bin ###在PATH环境变量中添加JAVA根目录下的bin子目录[root@server1 profile.d]# source java.sh ###java.sh脚本导入到环境变量中，使其生效[root@server1 ~]# java -version ###查看版本openjdk version "1.8.0_131"OpenJDK Runtime Environment (build 1.8.0_131-b12)OpenJDK 64-Bit Server VM (build 25.131-b12, mixed mode)

2.2、安装并启动Tomcat

[root@server1 opt]# tar zxf apache-tomcat-8.5.16.tar.gz[root@server1 opt]# mv apache-tomcat-8.5.16 /usr/local/tomcat8[root@server1 opt]# /usr/local/tomcat8/bin/startup.sh ###启动tomcatUsing CATALINA_BASE:   /usr/local/tomcat8Using CATALINA_HOME:   /usr/local/tomcat8Using CATALINA_TMPDIR: /usr/local/tomcat8/tempUsing JRE_HOME:        /usr/local/javaUsing CLASSPATH:       /usr/local/tomcat8/bin/bootstrap.jar:/usr/local/tomcat8/bin/tomcat-juli.jarTomcat started.[root@server1 opt]# /usr/local/tomcat8/bin/shutdown.sh ###关闭tomcatUsing CATALINA_BASE:   /usr/local/tomcat8Using CATALINA_HOME:   /usr/local/tomcat8Using CATALINA_TMPDIR: /usr/local/tomcat8/tempUsing JRE_HOME:        /usr/local/javaUsing CLASSPATH:       /usr/local/tomcat8/bin/bootstrap.jar:/usr/local/tomcat8/bin/tomcat-juli.jar[root@server1 ~]# ln -s /usr/local/tomcat8/bin/startup.sh /usr/bin/tomcatup ##优化执行路径[root@server1 ~]# ln -s /usr/local/tomcat8/bin/shutdown.sh /usr/bin/tomcatdown[root@server1 ~]# tomcatupUsing CATALINA_BASE:   /usr/local/tomcat8Using CATALINA_HOME:   /usr/local/tomcat8Using CATALINA_TMPDIR: /usr/local/tomcat8/tempUsing JRE_HOME:        /usr/local/javaUsing CLASSPATH:       /usr/local/tomcat8/bin/bootstrap.jar:/usr/local/tomcat8/bin/tomcat-juli.jarTomcat started.[root@server1 ~]# netstat -anpt | grep 8080tcp6       0      0 :::8080                 :::*                    LISTEN      48759/java[root@server1 ~]# systemctl stop firewalld[root@server1 ~]# setenforce 0

在浏览器中输入 http://192.168.158.10:8080 即可访问tomcat主页

2.3、Tomcat常用文件

●bin

存放启动和关闭Tomcat扽脚本文件，比较常用的是catalina.sh、startup.sh、shutdown.sh三个文件 ●conf 存放Tomcat服务器的各种配置文件，比较常用的是server.xml、context.xml、tomcat-users.xml、web.xml四个文件 ●lib 存放Tomcat服务器的jar包，一般不作任何改动，除非连接第三方服务，比如redis，那就需要添加相对应的jar包 ●logs 存放tomcat日志 ●temp 存放Tomcat运行时产生的文件 ●webapps 存放项目资源的目录 ●work Tomcat工作目录，一般清除Tomcat缓存的时候会使用到

三、配置虚拟主机

3.1、基于域名

1、创建主页并修改主页内容

[root@server1 ~]#  mkdir -p /var/www/html[root@server1 ~]#  mkdir -p /var/www/tom[root@server1 ~]#  mkdir -p /var/www/jerry[root@server1 ~]# vi /var/www/tom/index.jsp
tom

2、修改Tomcat主配置文件[root@server1 ~]# vi /var/www/jerry/index.jsp
jerry
#末行合适位置添加[root@server1 ~]# vi /web/webapp1/test1/index.jsp  
           
          
          
           
          
         

3、本地增加映射

[root@server1 ~]# vi /etc/hosts192.168.158.10 www.tom.com www.jerry.com
