(一)第一部分:最基本的jar包运行(无需配置tomcat)

[http://60.205.183.114:8081/]

a)安装jdk。
b)寻找jdk路径配置环境变量。
c)简单的Java hello world测试确保安装成功。

a)安装mysql、mariadb server。
b)systemctl 开启服务。
c) 打开端口。(阿里云要在控制台打开,参考https://yq.aliyun.com/articles/701181)
d) 更改mysql 的root密码,对应于项目配置文件中的密码。

a)传输spring maven 的快照版本用于测试。
b)传输数据库sql文件。

  • 5、导入数据库

a)创建sql文件对应的数据库。
b)利用文件重定向运行sql文件。
c)检查数据库是否导入成功

  • 6、运行jar文件,控制台获取公网IP,本机输入IP:8081测试。
  • 7、设置后台运行(已设置:http://60.205.183.114:8081/)

a)contrl+c中止。
b)然后通过nohup 和 & 来后台运行。
c)ps通过pid来停止后台运行进程。

运行结果
整体过程:

   39  ps
   40  history
[root@iZ2ze4r3b4xcztbcsey08cZ ~]# 

控制台开端口

利用scp传文件

运行mysql 文件

访问http://60.205.183.114:8081/

(二)第二部分:利用Tomcat容器对war包进行处理(需要Tomcat)

[http://60.205.183.114:8080/myJPetStore_war/index.jsp]

a)本地下载tomcat,然后利用scp文件传输
b)设置访问权限
c)设置服务配置
d)输入IP:8080测试是否已经开启服务

  • 2、数据库/端口配置

a)数据库root 密码 和服务器对应
b)端口配置,在上面已经开启了8080端口

  • 3、利用scp传输war包,放到webapp里边(直接会解析出文件)
  • 4、重启tomcat服务

a)bin下的shutdown.sh
b)bin下的startup.sh

  • 5、本机测试访问

a)注意要添加访问的资源的路径/myJPetStore_war/index.jsp,然后tomcat容器会自动到webapp下去寻找
b) 已设置tomcat容器:http://60.205.183.114:8080/myJPetStore_war/index.jsp

运行结果
整体过程

   52  ls
   53  sudo mkdir /opt/tomcat
   54  sudo tar xvf apache-tomcat-8*tar.gz -C /opt/tomcat --strip-components=1
   55  cd /opt/tomcat
   56  sudo chgrp -R tomcat /opt/tomcat
   57  sudo chmod -R g+r conf
   58  sudo chmod g+x conf
   59  sudo chown -R tomcat webapps/ work/ temp/ logs/
   60  sudo vi /etc/systemd/system/tomcat.service
   61  sudo systemctl daemon-reload
   62  sudo systemctl start tomcat
   63  sudo systemctl status tomcat
   64  sudo systemctl enable tomcat
   65  ls
   66  cd webapps/
   67  pwd
   68  ls
   69  sudo systemctl restart tomcat
   70  cd ../bin/
   71  ls
   72  sh shutdown.sh 
   73  sh startup.sh 
   74  history
[root@iZ2ze4r3b4xcztbcsey08cZ bin]# 

利用systemctl查看tomcat的状态
image

验证是否开启tomcat服务
image

将war包直接传入webapp中
image

然后webapp会自动解析war包(即myJPetStore_war)

[root@iZ2ze4r3b4xcztbcsey08cZ webapps]# pwd
/opt/tomcat/webapps
[root@iZ2ze4r3b4xcztbcsey08cZ webapps]# ls
docs  examples  host-manager  manager  myJPetStore_war  myJPetStore_war.war  ROOT

访问http://60.205.183.114:8080/myJPetStore_war/index.jsp

(三)第三部分:指定域名进行访问

[http://crf.codes/]

  • 1、配置virmach vps,达到可以通过IP进行访问

a)过程同第一步,最后设置为后台运行。
b) 已配置:http://198.12.120.212:8081/

a)Web server 设定域名
b)Location 配置index界面
c)开放Linux系统防火墙
d)访问crf.code http://crf.codes/

运行结果
域名提供商(name)配置dns

image

验证dns是否配置成功
ping crf.codes,可以看到
image

修改nginx配置文件

server {
    listen       80;
    server_name   crf.codes;

    #charset koi8-r;
    access_log  /var/log/nginx/host.access.log  main;

    location / {
        # root   /usr/share/nginx/html;
        index  index.html index.htm;
        proxy_pass http://127.0.0.1:8081/;
        # proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # proxy the PHP scripts to Apache listening on 127.0.0.1:80
    #
    #location ~ \.php$ {
    #    proxy_pass   http://127.0.0.1;
    #}

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    #location ~ \.php$ {
    #    root           html;
    #    fastcgi_pass   127.0.0.1:9000;
    #    fastcgi_index  index.php;
    #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
    #    include        fastcgi_params;
    #}

    # deny access to .htaccess files, if Apache's document root
    # concurs with nginx's one
    #
    #location ~ /\.ht {
    #    deny  all;
    #}
}

访问crf.codes
