centos7使用tomcat部署javaweb项目

1.下载二进制安装包

tomcat下载地址

 

2.下载jdk和配置环境变量

这里就不再多描述不清楚,可以       参考 我的yum安装的jdk

3.在centos7下安装 tomcat

#切换到/usr/local 目录下解压安装

[root@localhost local]# cd /usr/local/
[root@localhost local]# tar xf apache-tomcat-8.0.50.tar.gz 

#启动tomcat 脚本为startup.sh

[root@localhost local]# cd apache-tomcat-8.0.50/
[root@localhost apache-tomcat-8.0.50]# ./bin/startup.sh 
Using CATALINA_BASE:   /usr/local/apache-tomcat-8.0.50
Using CATALINA_HOME:   /usr/local/apache-tomcat-8.0.50
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-8.0.50/temp
Using JRE_HOME:        /usr/lib/jvm/java
Using CLASSPATH:       /usr/local/apache-tomcat-8.0.50/bin/bootstrap.jar:/usr/local/apache-tomcat-8.0.50/bin/tomcat-juli.jar
Tomcat started.

#登陆网页验证

如果不能显示,估计是防火墙,要么关闭防火墙或者防火墙设置开放8080端口的规则。

 

 #关闭tomcat脚本为shutdown.sh

[root@localhost apache-tomcat-8.0.50]# ./bin/shutdown.sh 
Using CATALINA_BASE:   /usr/local/apache-tomcat-8.0.50
Using CATALINA_HOME:   /usr/local/apache-tomcat-8.0.50
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-8.0.50/temp
Using JRE_HOME:        /usr/lib/jvm/java
Using CLASSPATH:       /usr/local/apache-tomcat-8.0.50/bin/bootstrap.jar:/usr/local/apache-tomcat-8.0.50/bin/tomcat-juli.jar

4.编写一个tomcat的启动脚本并加入service系统服务

[root@localhost apache-tomcat-8.0.50]# cat /etc/rc.d/init.d/tomcat 
#!/bin/bash
#chkconfig: 2345 10 90
#description: Starts and Stops the Tomcat daemon.
#by benjamin
##############################################
#Startup script for Tomcat on Linux


#filename tomcat.sh


#Make sure the Java and the tomcat installation path has been added to the PATH
JAVA_HOME=/usr/lib/jvm/java                  #JDK安装目录
CATALINA_HOME=/usr/local/apache-tomcat-8.0.50           #tomcat安装目录
export JAVA_HOME
export CATALINA_HOME


###############################################
start_tomcat=$CATALINA_HOME/bin/startup.sh              #tomcat启动文件
stop_tomcat=$CATALINA_HOME/bin/shutdown.sh                  #tomcat关闭文件
start() {                                                              
        echo -n "Starting tomcat: "
        ${start_tomcat}
        echo "tomcat start ok."
}
stop() {
        echo -n "Shutting down tomcat: "
        ${stop_tomcat}
        echo "tomcat stop ok."
}
# See how we were called
                                                   
case "$1" in
  start)
        start
        ;;
  stop)
        stop
        ;;
  restart)
        stop
        sleep 10
        start
        ;;
  *)
        echo "Usage: $0 {start|stop|restart}"
esac
exit 0

 

 

#给启动脚本授权

chmod 755 /etc/rc.d/init.d/tomcat

 

 

#将tomcat加入到系统服务中

chkconfig --add /etc/rc.d/init.d/tomcat

 

# 在tomcat中的catalina.sh文件中添加如下变量

vim /usr/local/apache-tomcat-8.0.50/bin/catalina.sh
#在配置文件中加入如下变量
export JAVA_HOME=/usr/lib/jvm/java #javajdk的安装路径,使用echo $JAVA_HOME命令可以读取 export CATALINA_HOME=/usr/local/apache-tomcat-8.0.50 export CATALINA_BASE=/usr/local/apache-tomcat-8.0.50 export CATALINA_TMPDIR=/usr/local/kencery/apache-tomcat-8.0.50/temp

# 验证是否已加入service

[root@localhost apache-tomcat-8.0.50]# service tomcat start
Starting tomcat: Using CATALINA_BASE:   /usr/local/apache-tomcat-8.0.50
Using CATALINA_HOME:   /usr/local/apache-tomcat-8.0.50
Using CATALINA_TMPDIR: /usr/local/kencery/apache-tomcat-8.0.50/temp
Using JRE_HOME:        /usr/lib/jvm/java
Using CLASSPATH:       /usr/local/apache-tomcat-8.0.50/bin/bootstrap.jar:/usr/local/apache-tomcat-8.0.50/bin/tomcat-juli.jar
Tomcat started.
tomcat start ok.

 

5.设置tomcat开机自启动

#在开机自启动文件中导入 tomcat的相关路径和所依赖的jdk相关路径

[root@localhost ~]# cat /etc/rc.d/rc.local 
#!/bin/bash
# THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES
#
# It is highly advisable to create own systemd services or udev rules
# to run scripts during boot instead of using this file.
#
# In contrast to previous versions due to parallel execution during boot
# this script will NOT be run after all other services.
#
# Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure
# that this script will be executed during boot.

touch /var/lock/subsys/local
export JAVA_HOME=/usr/lib/jvm/java  
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar  
export PATH=$PATH:$JAVA_HOME/bin  
export CATALINA_HOME=/usr/local/apache-tomcat-8.0.50/
#tomcat自启动  
$CATALINA_HOME/bin/startup.sh 

# reboot后检查8080端口是否还在,在的话证明开机启动设置ok

[root@localhost ~]# netstat -lntup|grep 8080
tcp6       0      0 :::8080                 :::*                    LISTEN      625/java  

6.给tomcat网页设置登陆帐号密码

a.   当tomcat安装完成之后,访问http://ip:8080即可以看到tomcat发布的网站,若要管理我们发布的网站,就需要登录tomcat,下面就进行用户名和密码的设置。

b.   在tomcat安装包下面的conf文件下含有一个tomcat-usrs.xml文件,修改此文件即可,命令如下:

vim tomcat-users.xml
<role rolename="admin-gui"/>     
<role rolename="manager-gui"/>  
<user username="tomcat" password="tomcat" roles="manager-gui,admin-gui"/>  
#如若我们现在想访问tomcat中图形化管理应用的功能,也就是Manager App,就需要指定manager-gui的权限,如果想访问host manager就必须指定admin-gui权限

c.重启tomcat

[root@localhost conf]# service tomcat restart

7.使用eclipse打包java web项目

以上所有工作完成之后,我们需要将自己要发布的项目打包,那么在MyEclipse中如何打包项目呢?

a.   随便创建一个JavaWeb项目,如图所示:

 

 

b.   在项目上单击右键选择【Export】-【MyEclipse JavaEE】文件夹-【WAR file】,单击【Next>】如图所示,选择存放打包程序的地址,单击【Finish】完成,即实现了打包,在完成之后可以去你打包的地方看一下是否打包成功。

 

 

d.   MyEclipse10.7打包程序的时候当选择【WAR file】,单击【Next>】的时候IDE崩溃的解决办法。

 

d.1   此错误可能是在破解的时候没有破解的很干净,所以需要执行下面的步骤;

d.2   下载文件com.genuitec.eclipse.export.wizard_9.0.0.me201211011550.jar ,下载地址为:

d.3   找到MyEclipse安装环境的地址,我的安装环境是:

D:\Program Files\MyEclipse\Common\plugins ,将下载下来的文件解析之后替换到plugins中的同名文件(替换后,最好将jar文件改成.txt文件结尾,然后重启MyEclipse10,然后关闭,再将jar改回.jar为扩展名的状态,重启后即可)。

    d.4   已测试,没任何问题,完美实现,如果大家遇到,则按照该方法解决即可。

 

 

8、将Java Web项目发布到tomcat8.0下面并且访问展示

 

a.   以上所有工作都完成之后,完美就可以将打包的JavaWeb程序发布到tomcat下即可。

b.   tomcat默认的发布web项目的目录是:webapps

c.   将导出的war包拷贝到webapps根目录下,随之tomcat的启动,war包可以自动被解析。

[root@localhost ROOT]# pwd
/usr/local/apache-tomcat-8.0.50/webapps/ROOT

 

d.   然后在浏览器中输入路径链接,查询是否安装成功,如下图所示,则表示安装成功:

 

 

大功告成,成功!!!
