【云服务器】ubuntu18.04系统的TOMCAT项目部署

安装JAVA JDK1.8

环境信息：
OS：Ubuntu18.04
JDK：1.8

1、查看ubuntu版本

root@VM-0-12-ubuntu:/usr# uname -a
Linux VM-0-12-ubuntu 4.15.0-88-generic #88-Ubuntu SMP Tue Feb 11 20:11:34 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

2、下载对应的jdk8

https://pan.baidu.com/s/1EphlSzhD9uyq5XmMu34h6A 提取码: 554m

3、建立一个目录，把文件传输过去，解压缩

tar -zxvf jdk-8u221-linux-x64.tar.gz

4、移动到/usr/local/jdk1.8目录

sudo mv jdk1.8.0_221 /usr/local/jdk1.8

5、设置环境变量

nano /etc/profile

6、在文件末尾加入

export JAVA_HOME=/usr/local/jdk1.8
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=.:${JAVA_HOME}/bin:$PATH

7、使配置生效

source /etc/profile

8、检查是否安装正常

root@VM-0-12-ubuntu:/usr# java -version
java version "1.8.0_221"
Java(TM) SE Runtime Environment (build 1.8.0_221-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.221-b11, mixed mode)

9、输入javac出现有提示

root@VM-0-12-ubuntu:/usr#

安装Tomcat

环境信息：
OS：Ubuntu18.04
JDK：1.8
Tomcat: 9.0.35

1、下载Tomcat

根据自己系统，下载相应版本Tomcat，这儿下载tar.gz

https://tomcat.apache.org/download-90.cgi

2、安装配置

把tomcat传到服务器上

tar -zxvf apache-tomcat-9.0.35.tar.gz

移动到/usr/local/目录下

sudo mv apache-tomcat-9.0.35 /usr/local/apache-tomcat-9.0.35

进入apache目录，修改tomcat服务器的启动端口，修改为自己想要的端口，改为80的话，访问网页的时候就不需要加端口号，这儿建议大家使用80端口

root@VM-0-12-ubuntu:/usr/local/apache-tomcat-9.0.35# nano conf/server.xml

3、cat服务器的启动和关闭

启动tomcat

进入tomcat服务器目录，然后执行"./bin/startup.sh"命令启动Tomcat服务器

关闭tomcat

进入tomcat服务器的bin目录，然后执行"./bin/shutdown.sh"命令启动Tomcat服务器

4、华为云耀云服务器配置

配置完毕后，对于华为云耀云，可以通过本地访问，安装w3m，使用

w3m http://localhost

但是远程访问仍旧无法访问

此时我们需要更改安全组配置，装系统时的默认只开放了3389和22端口。

我们在更改安全组里面，选择Sys-webserver，即可以通过远程正常访问。

通过IP访问后即能够正常打开。

安装w3m

 sudo apt install w3m

打开网页

w3m www.baidu.com
w3m localhost:80
