Web project deployment

Our project , After all, it should be deployed to the server , Will have the sense of accomplishment of ending the flower scattering ;

How to deploy to Linux Server for , Realize the real browser website to visit you ？

1. To have a Cloud server

Alibaba cloud , Tencent, cloud, etc.

0. What is deployment

Involved in the work " Environmental Science "

• development environment : A machine used by programmers to write code .
• Test environment : The tester tests the machine used by the program . It is usually a retired deployment machine .
• Production environment ( The online environment ): The machine used when the final project is released . High requirements for stability .

Install the program copy to the production environment , This process is called " Deploy ". Also called " go online ".

This process requires copying the corresponding .class Files and dependent resource files ( Various configuration files , html etc. )

Once the program is successfully deployed , Then this program can be accessed by thousands of ordinary users in the Internet .

let me put it another way , If the program has BUG, This BUG It will be seen by millions of users .

The deployment process is critical , It is the most important part of program development . In case of deployment problems , It is very likely to lead to serious accidents ( The server Not available or something ).

To prevent deployment errors , Generally, there are some automatic deployment tools in the company ( Such as Jenkins etc. ). At present, we first use the manual deployment method To complete the deployment .

1. Database tables

Follow the previous database creation script , Run on the server , Create the same table structure

mysql -u[ Database user name ] -p[ Database password ] < [ Database script ].sql

Or create... Manually , Copy and paste

2. pack

Put the previously marked war Put the package in the specified directory （Tomcat webapps）

XShell You can directly drag and drop in （ Enter ahead of time webapps Catalog ）

If you can't drag and drop files , install

yum install lrsz

Be careful ：

Before war package Run locally , Access local database , Now on ECs , Access cloud server

Make sure the database , The connection is correct （URL,IP, user name , password , Cloud server , There is a corresponding database ）

3. Is to verify the access

Enter the correct... In the browser URL You can access your own projects
