作为大型的web应用一般需要开源的Linux操作系统作为底层支撑，一方面是为了考虑软件性能，另一方面是为了保证系统的灵活稳定性。
所以根据工作需要，这次分享Linux下利用apache tomcat来搭建一套Web应用系统的方法。
环境：CentOS Linux release 7.3.1611（ 下载地址） apache tomcat版本：7.0.90（ 下载地址）
Linux部署后关闭防火墙以备tomcat的正常运行。
配置好网络等基础设置后，开始部署apache tomcat。
可以使用xshell登陆Linux使用xftp把已经下载好的apache-tomcat-7.0.90.tar.gz安装包放到Linux /tmp目录下。
Linux中解压： tar -zxvf apache-tomcat-7.0.90.tar.gz 解压完毕后会在当前目录下生成一个文件夹：apache-tomcat-7.0.90
好，其实到这里就已经成功了一半了，剩下的就是把自己的Web项目打包war包拖到指定的目录下即可。
拖放war包到目录：/tmp/apache-tomcat-7.0.90/webapps下，配置/tmp/apache-tomcat-7.0.90/conf/server.xml文件。

默认的server.xml文件中缺少配置，我们需要加入上述代码中的红色部分，来指明自己的web项目文件所在目录（也就是war包解压后的所在目录，如：/tmp/apache-tomcat-7.0.90/webapps/war）
然后到/tmp/apache-tomcat-7.0.90/bin下开启tomcat。 - [root@localhost bin]# sh startup.sh
- Using CATALINA_BASE: /tmp/apache-tomcat-7.0.90
- Using CATALINA_HOME: /tmp/apache-tomcat-7.0.90
- Using CATALINA_TMPDIR: /tmp/apache-tomcat-7.0.90/temp
- Using JRE_HOME: /usr/local/jdk
- Using CLASSPATH: /tmp/apache-tomcat-7.0.90/bin/bootstrap.jar:/tmp/apache-tomcat-7.0.90/bin/tomcat-juli.jar
- Tomcat started.
然后ss -ant查看端口是否开启。
- [root@localhost logs]# ss -ant
- State Recv-Q Send-Q Local Address:Port Peer Address:Port
- LISTEN 0 128 *:111 *:*
- LISTEN 0 128 *:22 *:*
- LISTEN 0 100 127.0.0.1:25 *:*

- ESTAB 0 0 192.168.1.139:22 192.168.1.102:4344
- ESTAB 0 52 192.168.1.139:22 192.168.1.102:3858
- LISTEN 0 128 :::111 :::*
- LISTEN 0 100 :::8080 :::*
- LISTEN 0 128 :::22 :::*
- LISTEN 0 100 ::1:25 :::*
- LISTEN 0 1 ::ffff:127.0.0.1:8005 :::*
- LISTEN 0 100 :::8009 :::*
- TIME-WAIT 0 0 ::ffff:127.0.0.1:41914 ::ffff:127.0.0.1:8005
看到8080端口已经开启，就可以浏览器访问测试下：
大功告成！ |
