Going to do

This article is about deploying a Java Web project (mine is a Maven project for SSM) on a cloud server.

Preparation:

  • A war file packaged as a project that can be run locally
  • The balance of alipay is 10 yuan

Environment:

  • Ali Cloud Server ECS System Linux (centOS 7.2)
  • JDK 1.8
  • Tomcat 9.0
  • Mysql 5.7.27

buy

Ali cloud cloud wing students plan ($9.5) a month: promotion.aliyun.com/ntms/act/ca…

There are two models :(the second one I bought seems to have the same performance)

  • Lightweight application server: Suitable for beginners

  • Cloud server ECS

    Get an instance after successful purchase: Login – console – Cloud server ECS- instance (buy without password to reset the password)

Remote connection use

  • The instance page has a remote connection, click and then follow the operation to enter, account password is root and you set the secret

  • Use XShell (jailbroken blog.csdn.net/qq_31362105…

  1. The new session

    • Name: Name yourself

    • Protocol: indicates the default SSH

    • Host: public IP address of Ali Cloud service (see the ECS instance list page)

    • Port: the default is 22

  2. When you click connect, you will be asked to enter your password (root and your secret).

    Success will be displayed as follows

File transfer tool

The file transfer tool is a tool for the interaction between the local machine and the server files. Just now, the JDK download was directly downloaded from the Linux server by command, and the tomcat installation will use the file transfer method, that is, after downloading on the local machine (I am Windows 10), it will be transferred to the server through this tool. Later our project (WAR package, SQL file, etc.) will also need to be used when it is passed to the server.

I have used XFTP (after the trial charge, cracked version did not find), and then changed to FileZilla(open source free, Baidu official website download)

FileZilla is used here. After installation, open it to connect

Install the JDK

I have installed all these environments in /home/money/. Money is my own folder. Therefore, it is best to enter all commands in this directory

  1. Download:

    The cloud: pan.baidu.com/s/1_Slgq1Jx… Extraction code: H57L

    Download the.tar.gz suffix JDK and pass it in using the file transfer tool

  2. Unzip: I am all put in home/money

    tar xzf jdk-8u212-linux-x64.tar.gz -C /home/money
Copy the code

  3. Configure Java environment variables:

    vim /etc/profile
Copy the code

  4. At the bottom of the configuration file add:

    Export JAVA_HOME = / home/money/jdk1.8.0 _144 export CLASSPATH = $JAVA_HOME/lib/tools. The jar: $JAVA_HOME/lib/dt. The jar: $JAVA_HOME/lib  export PATH=$JAVA_HOME/bin:$PATHCopy the code

  5. The configuration environment takes effect

    source /etc/profile
Copy the code

Install Tomcat9.0

  1. Download tomcat.apache.org/download-90… Select the.tar.gz download

  2. Upload the downloaded file to /home/money/

  3. Install apache-tomcat-9.0.26.tar.gz is the file name downloaded

    Tar xf apache-tomcat-9.0.26.tar.gz -c /home/moneyCopy the code

  4. After the installation is successful, modify the environment variables of Tomcat (this step can be used even if it is not configured during the second installation, it seems not necessary)

    [root@Tomcat ~]# vim /home/money/apache-tomcat-9.0.26/bin/startup
[root@Tomcat ~]# vim /home/money/apache-tomcat-9.0.26/bin/shutdown
Copy the code

    Sh/startup.sh/shutdown.sh/startup.sh/shutdown.sh

     exportJAVA_HOME = / home/money/jdk1.8.0 _212exportTOMCAT_HOME = / home/money/apache tomcat -- 9.0.26exportThe CATALINA_HOME = / home/money/apache tomcat -- 9.0.26export CLASS_PATH=$JAVA_HOME/bin/lib:$JAVA_HOME/jre/lib:$JAVA_HOME/lib/tool.jar
 export PATH=$PATH: / home/money/jdk1.8.0 _212 / bin: / home/money/apache tomcat - 9.0.26 / binCopy the code

  5. Change the host localhost in server. XML to your server’S IP address

  6. On the ECS page of the cloud server, choose Network and Security > Security Groups > Configuration Rules > Add security Rules

  7. open

Sh # Enable /home/money/apache-tomcat-9.0.26/bin/startup.sh # Enable /home/money/apache-tomcat-9.0.26/bin/shutdownCopy the code

  1. access

    Http://your exet IP :8080 Showing apache’s home page represents success

Mysql installation

Run the following command in the directory you want to install. This is where I go to /home/money/ and run the following command

  1. download

    wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
Copy the code

  2. Yum install

    yum -y install mysql57-community-release-el7-10.noarch.rpm
Copy the code

  3. Installing the mysql Server

    yum -y install mysql-community-server
Copy the code

  4. Start the service

    service mysqld start
Copy the code

  5. Change the password

    For the first installation, root is given a random password. Run the grep “password” /var/log/mysqld.log command

    Enter the password of the database mysql -uroot -p

    Default password tape'('Deng did not enter the solution: https://blog.csdn.net/qq_42910468/article/details/99692105Copy the code

    ALTER USER ‘root’@’localhost’ IDENTIFIED BY ‘; (To include case and symbol, difficult to set)

  6. Mysql > modify mysql

    First log in to mysql again and type status:

    The language is not UTF8, so we need to change it by exiting (type exit)

    vi /etc/my.cnf
Copy the code

    Add four lines of code

    Mysql > restart the mysql server, log in to the mysql server, and change the status to UTf8

    service mysqld restart
Copy the code

Operation command:

Start the mysql service service service mysqld restart Check the mysql service status service mysqld statusCopy the code

Deploying a JAVA Web project (WAR package)

First shut down Tomcat, I need to package the local Java Web project into WAR, and export the database to SQL file and upload it to the server. Put the project’s WAR package into tomcat’s webapps directory and start Tomcat. After tomcat runs, it will automatically unpack it and you can use the path to access it.

(For database import, you need to create a database with the same name under mysql command, and then run source data.sql.)

Matters needing attention

  1. Mysql/mysql.mysql/mysql.mysql/mysql.mysql/mysql.mysql/mysql.mysql/mysql.mysql/mysql.mysql
  2. About a file upload, Linux without \ operator and drive, such as Windows, path directly is/on behalf of the root directory, file upload is like me in/home/money/tonynews/uploads, The file upload path is writing/home/money/tonynews/uploads/filename

I set the base path

Second context: map file path

Tomcat virtual path mapping do not know to baidu, here is to provide some ideas.
