阿里云 Centos7 部署Java web [jar/war/virmach+vps+域名服务]
(一)第一部分：最基本的jar包运行(无需配置tomcat) [http://60.205.183.114:8081/] 1、配置阿里云(Esc学生服务器、镜像Centos7.7)，并远程连接进入终端。 2、安装并配置JDK(参考https://www.jianshu.com/p/093413f2a04f)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。 3、安装并配置mysql(mariadb)(参考https://blog.csdn.net/DaSo_CSDN/article/details/54754936)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。 4、利用scp进行文件传输(参考https://www.cnblogs.com/tugenhua0707/p/8278772.html)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: [root@iZ2ze4r3b4xcztbcsey08cZ ~]# history 1 MAKRER=SHOW_LOCALE;printf $MAKRER""; locale; MAKRER=SHOW_LOCALE;printf $MAKRER""; 2 yum install -y mysql 3 yum install -y mariadb-server mariadb 4 systemctl start mariadb 5 systemctl enable mariadb 6 yum install -y mysql-devel 7 firewall-cmd --zone=public --add-port=3306/tcp --permanent 8 CHECK_TYPE=SHELL; echo "INFO=${CHECK_TYPE} PID=$$ PPID=$PPID TTY=$(tty) SHELL=$0 HOME=$HOME PWD=$PWD| CHECK_SHELL_END" 9 ls 10 ifconfig 11 ls 12 yum list 13 java -version 14 ls 15 yum search java-1.8 16 yum -y install java-1.8.0-openjdk-devel.x86_64 17 java -version 18 cd /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.252.b09-2.el7_8.x86_64/ 19 pwd 20 vim /etc/profile 21 . /etc/profile 22 vim Demo.java 23 javac Demo.java 24 java Demo 25 su 26 MAKRER=SHOW_LOCALE;printf $MAKRER""; locale; MAKRER=SHOW_LOCALE;printf $MAKRER""; 27 CHECK_TYPE=SHELL; echo "INFO=${CHECK_TYPE} PID=$$ PPID=$PPID TTY=$(tty) SHELL=$0 HOME=$HOME PWD=$PWD| CHECK_SHELL_END" 28 mysql -u root 29 ls 30 pwd 31 ifconfig 32 ls 33 mysql 34 mysql -u root jpetstore < jpetstore.sql 35 mariadb 36 mysql 37 java -jar mypetstore-0.0.3-SNAPSHOT.jar 38 nohup java -jar mypetstore-0.0.3-SNAPSHOT.jar & 39 ps 40 history [root@iZ2ze4r3b4xcztbcsey08cZ ~]# 控制台开端口 利用scp传文件 运行mysql 文件 [root@iZ2ze4r3b4xcztbcsey08cZ ~]# mysql Welcome to the MariaDB monitor.
